191 Cruise Control R Suspending Cruise Control Cruise Control can be suspended by a single press of the Suspend switch (4). The warning indicator in the instrument pack extinguishes. Cruise Control will also suspend when the brake pedal is pressed, when the gear selector is moved into neutral or if HDC or DSC becomes active. To resume Cruise Control at the previously set speed, press the Resume switch (3). Note: The set speed will NOT be erased by pressing the Suspend switch (4). The set speed will only be erased when the starter switch is turned to position ’0’. To reduce the cruising speed: Press and hold the ’-’ switch (2); the vehicle will decelerate. Release the switch as soon as the desired speed is reached. The vehicle speed at the point of switch release becomes the new set speed. Alternatively, the set speed can be decreased incrementally by tapping the ’-’ switch. Each press of the switch will decrease the speed by 1 km/h. Note: Cruise Control will not operate at speeds below 30 km/h (18 mph).To increase the set cruising speed: Press and hold the ’+’ switch (1); the vehicle will accelerate. Release the switch as soon as the desired speed is reached. The vehicle speed at the point of switch release becomes the new set speed. Alternatively, the set speed can be increased incrementally by tapping the ’+’ switch. Each press of the switch will increase the speed by 1 km/h. A further alternative is to increase speed by normal use of the accelerator. When the desired speed is reached, press the ’+’ switch (1) to set the Cruise Control. Note: If the accelerator pedal is pressed to increase speed, but the ’+’ switch (1) is not pressed, cruise control will be cancelled after a set period. WARNING When setting the cruise control to the speed limit it is important to remember that it is possible for the vehicle speed to increase when travelling downhill. This may result in the vehicle exceeding the speed limit. The driver must always ensure that a safe speed is maintained below the speed limit, taking traffic and road conditions into account.
Brakes 192 L Brakes FOOT BRAKE For your safety, the hydraulic braking system operates through dual circuits. If one circuit should fail, the other will continue to function. However, in the event of brake failure where only one circuit is operational, the vehicle should only be driven at slow speed to the nearest qualified Land Rover Retailer. In these circumstances, exercise extreme caution and be aware that increased brake pedal travel, greater pedal pressure, and longer stopping distances will be experienced. Servo assistance The braking system is servo assisted, but ONLY when the engine is running. Without this assistance greater braking effort is necessary to safely control the vehicle, resulting in longer stopping distances. Always observe the following precautions: •ALWAYS take particular care when being towed with the engine turned off. •If the engine should stop for any reason while the vehicle is in motion, bring the vehicle to a halt as quickly as traffic conditions safely allow, and DO NOT pump the brake pedal as the braking system may lose any remaining assistance available. Brake pads Brake pads require a period of bedding in. For the first 800 km (500 miles), you should avoid situations where heavy braking is required. Remember! Regular servicing is vital to ensure that the brake pads are examined for wear and changed periodically to ensure long term safety and optimum performance. WARNING DO NOT rest your foot on the brake pedal while travelling as this may overheat the brakes, reduce their efficiency and cause excessive wear. NEVER allow the vehicle to freewheel with the engine turned off as braking assistance will not be available. The pedal brakes will still function, but more pressure will be required to operate them. If the RED brake warning indicator should illuminate while the vehicle is in motion, bring the vehicle to a halt as quickly as traffic conditions and safety allow and seek qualified assistance before continuing, see Warning Indicators, 108. NEVER place non-approved floor matting or any other obstructions under the brake pedal. This restricts pedal travel and braking efficiency. Wet conditions Driving through water or even very heavy rain may adversely affect braking efficiency. Always dry the braking surfaces by intermittent light application of the brakes, first ensuring that you are at a safe distance from other road users.
193 Brakes R ANTI-LOCK BRAKES The purpose of the anti-lock braking system (ABS) is to allow efficient braking without wheel locking - thereby allowing the driver to retain steering control of the vehicle. Under normal braking conditions, where sufficient road surface friction exists to slow the vehicle without the wheels locking, ABS will not be activated. However, if the wheels begin to lock under braking, then ABS will automatically come into operation. This will be recognisable by a rapid pulsation felt through the brake pedal. In an emergency situation, ABS functions most effectively when full braking effort is applied even when the road surface is slippery. The ABS system constantly monitors the speed of each wheel and varies the brake pressure to each, according to the available grip. No matter how hard you brake, you should be able to continue steering the vehicle as normal. •DO NOT pump the brake pedal at any time; this will interrupt operation of the system and may increase the stopping distance. •NEVER place additional floor matting or any other obstruction under the brake pedal. This restricts pedal travel and may impair brake efficiency. WARNING ABS cannot overcome the physical limitations of braking distance, or the danger of aquaplaning, i.e. where a layer of water prevents adequate contact between the tires and the road surface. The fact that a vehicle is fitted with ABS must never tempt the driver into taking risks that could affect safety. In all cases, it remains the drivers responsibility to drive within normal safety margins, having due consideration for prevailing weather and traffic conditions. The driver should always take account of the surface to be travelled over and the fact that brake pedal reactions will be different to those experienced on a non-ABS vehicle. Warning indicator A fault with the ABS system is indicated by illumination of the amber ABS warning indicator. If the indicator illuminates, drive with care, avoiding heavy brake applications and seek qualified assistance urgently. For further information on the functionality of the ABS warning indicator, see Anti-lock braking system - AMBER, 111.
Brakes 194 L Off-road driving While anti-lock braking will operate in ’off-road’ driving conditions, on certain surfaces total reliance on the system may be unwise. It cannot reliably compensate for driver error or inexperience on difficult off-road surfaces. Note the following: •On soft or deep surfaces such as powdery snow, sand or gravel, and on extremely rough ground, the braking distance required by the anti-lock braking system may be greater than for normal braking, even though improved steering would be experienced. This is because the natural action of locked wheels on soft surfaces is to build up a wedge of surface material in front which assists the wheels to stop. •If the vehicle is stopped on a very steep slope where little traction is available, it may slide with the wheels locked as there is no wheel rotation to provide a signal to the ABS. To counteract this, briefly release the brakes to permit some wheel movement, then re-apply the brakes to allow ABS to gain control. •Before driving off-road, read and thoroughly understand the ’Off-road driving’ section of this handbook. Cornering Brake Control (CBC) Cornering Brake Control (CBC) is an advanced form of ABS, which maintains vehicle stability and steering control during braking whilst cornering or changing lanes at speed.Emergency Brake Assist (EBA) If rapid full brake application is made, EBA automatically boosts the braking force to the maximum and helps to stop the vehicle. Also, if the driver brakes more slowly, but with sufficient brake pressure to activate ABS on both front wheels, the system automatically increases the braking force so that all four wheels are in ABS control, optimising the performance of the ABS system. Pressure should be maintained on the brake pedal during the entire brake application. If the brake pedal is released, EBA will cease operation. A fault with the EBA system is indicated by illumination of the amber brake warning indicator, see INDICATOR GROUPING, 108. In the event of a fault, the system should be checked by a Land Rover Retailer at the earliest opportunity. Electronic Brake Force Distribution (EBD) Your vehicle is equipped with Electronic Brake Force Distribution (EBD), which balances the distribution of braking forces between front and rear axles to maintain maximum braking efficiency under all vehicle loading conditions. For example; under light loads EBD applies less effort to the rear brakes to maintain vehicle stability; conversely allowing full braking effort to the rear wheels when the vehicle is towing or is heavily laden. A fault with the EBD system is indicated by illumination of the red brake warning indicator. If this illuminates while the vehicle is being driven, gently stop the vehicle as soon as safety permits and seek qualified assistance.
195 Brakes R PARKBRAKE Your vehicle is equipped with an electrically operated parkbrake (EPB). Applying the parkbrake manually With the vehicle stationary, pull up the lever (1) located alongside the gear selector, and release it. The lever will return to the neutral position and the red parkbrake warning indicator in the instrument pack will illuminate.It is important to confirm that the red indicator is continuously illuminated (not flashing). This indicates that the parkbrake has been correctly applied. If the lever is operated while the vehicle is travelling at less than 3 km/h, the vehicle will be brought to a stop abruptly. The stop lamps will not illuminate. If the system detects a fault with the parkbrake, the amber parkbrake warning indicator will illuminate and the message ’Parkbrake fault’ will appear on the instrument pack. If a fault is detected while EPB is operated, the red warning indicator will flash and the amber indicator will illuminate. Also the message ’Parkbrake fault. System not functional.’ will appear on the instrument pack. The red indicator will continue to be illuminated for at least ten seconds after the ignition has been switched off. WARNING DO NOT rely on the parkbrake system to hold the vehicle stationary if the amber parkbrake warning indicator is illuminated and/or the red warning indicator is flashing. Seek qualified assistance urgently. Note: Text messages described within this section are only available where a vehicle is fitted with a driver information module. Dynamic operation In an emergency, the parkbrake can be applied ’dynamically’, i.e. with the vehicle travelling at more than 3 km/h (2 mph). Pulling up on the lever and holding it up gives a gradual reduction in speed. The brake warning indicator will illuminate accompanied by a harsh sound and ’Caution! Parkbrake applied’ appears on the message screen. The stop lamps will illuminate. Releasing or depressing the lever will cancel the parkbrake application. H5601L 1 2
Brakes 196 L The parkbrake should not be used regularly to decelerate the vehicle or to bring it to a standstill; this facility is intended for emergency use only. Caution: Driving the vehicle with the parkbrake applied (other than in the emergency situation described above) or repeated use of the parkbrake to decelerate the vehicle may cause serious damage to the brake system. Releasing the parkbrake manually To disengage the parkbrake, the ignition must be on. Apply pressure to the footbrake or accelerator pedal while pressing down on the lever (2). It is not possible to manually release the parkbrake without pressing the footbrake or accelerator. WARNING The parkbrake operates on the rear wheels of the vehicle and hence secure parking of the vehicle is dependent on being on a hard and stable surface. DO NOT rely on the parkbrake to operate effectively if the vehicle has been subjected to immersion in mud and water. DO NOT rely on the parkbrake system to hold the vehicle stationary if the amber parkbrake warning indicator is illuminated and/or the red warning indicator is flashing. Seek qualified assistance urgently.Releasing the parkbrake automatically If the vehicle is stationary with the parkbrake applied, pressing the accelerator will release the parkbrake and allow the vehicle to move off. It is not possible to automatically release the parkbrake without pressing the accelerator. If you want to move the vehicle without pressing the accelerator, then manual release should be used. Automatic release is available in first, second and reverse gears in HIGH range, and first, second, third and reverse gears in LOW range. To delay the automatic release feature, hold the lever in the ’apply’ position, then at the desired point, release it. To assist in a smooth drive-away, the system anticipates the requirement and reduces the system load depending on the gradient. (It may be possible to hear this ’pre-arm’ operation). If the reduction in load causes the vehicle to move after a valid gear is engaged, the full system load will be re-applied to the parkbrake. This may cause a small reduction in the refinement of the subsequent drive-away. It is also possible to override this load reduction by lifting the parkbrake lever after gear engagement. In the event of a fault, ’Parkbrake Fault. Auto Release not functional’ will appear in the instrument pack. Under most conditions the EPB system will release seamlessly as the accelerator is applied, allowing the vehicle to move forward. However, release times may be extended for an initial time period at the start of a journey when changing into gear from ’P’ or ’N’. This is normal and is to allow for the extended gear engagement times that may occur under certain circumstances.
197 Brakes R Fault management If a fault is diagnosed by the system when the ignition is on but the parkbrake is not in use, the amber parkbrake warning indicator will flash and the message ’Parkbrake fault’ will be displayed. Note: Under some transmission fault conditions parkbrake release may not be automatic and/or automatic parkbrake function may be inoperable. Releasing the parkbrake in an emergency If the vehicle has the parkbrake applied and an electrical fault prevents the system operating normally, there is provision for mechanically releasing the parkbrake. Note: Whenever possible, this operation should be carried out by Roadside Assistance. WARNING As this operation removes the static braking on the vehicle, chocks must be placed on both sides of one of the wheels or the foot brake must be applied before releasing the cable. This procedure could take considerable physical effort. Using a suitable tool such as a screwdriver, lift out the coin tray situated on the opposite side of the gear shift lever from the parkbrake; this reveals a stirrup cable end. Attach the jack handle to the cable loop, insert the screwdriver shaft into the jack handle and pull to release the parkbrake cable.Once the failure conditions have been corrected, the parkbrake switch must be applied to reinstate normal function. If the vehicle is used in severe off-road conditions such as wading, deep mud, etc, additional maintenance and adjustment of the parkbrake will be required. Consult your Land Rover Retailer H5603L
Dynamic Stability & Traction Control 198 L Dynamic Stability & Traction Control DYNAMIC STABILITY CONTROL (DSC) DSC helps to optimise dynamic stability, even in critical driving situations. The system controls dynamic stability when accelerating. Additionally, it identifies unstable driving behaviour, such as understeering and oversteering and helps to keep the vehicle under control by manipulating the engine output and applying the brakes at individual wheels. Some noise may be generated when the brakes are applied. The system is ready to operate each time the engine is started. WARNING Dynamic Stability Control (DSC) is unable to compensate for driver misjudgement. It remains the driver’s responsibility to adopt a suitable driving style in every driving situation. Risks should never be taken on account of the additional security afforded by the DSC system. Warning indicator The indicator illuminates briefly as a bulb and system check when the starter switch is turned to position ’II’. If the warning indicator flashes, the system is active, regulating engine output and brake forces. If the indicator illuminates constantly, and does not extinguish when the DSC switch is pressed, a fault has been detected in the system. Any fault will deactivate DSC. Drive with care and seek qualified assistance as soon as possible. Deactivating DSC operation Land Rover recommend that DSC is operational in all normal driving conditions.In some driving conditions, to maximise traction, it may be beneficial to deactivate DSC. Such conditions include: •To ’rock’ the vehicle out of a hollow or out of a soft surface. •Starting in deep snow or on a loose surface. •Driving in deep sand. •Driving on tracks with deep longitudinal ruts. •Driving through deep mud. To deactivate DSC, press and briefly hold the DSC switch on the instrument panel (the DSC warning indicator will illuminate continuously). Deactivating DSC has no effect on traction control operation. Note: Driving with DSC deactivated, may add additional loads on the brakes - always drive with DSC switched on if possible. H5846N
199 Dynamic Stability & Traction Control R Reactivating DSC To reactivate DSC, press and briefly hold the DSC switch on the instrument panel. DSC will automatically reactivate when the engine is started. DSC is reactivated automatically when the program is changed on vehicles fitted with the Terrain Response * system. ELECTRONIC TRACTION CONTROL (ETC) ETC is continuously available to boost vehicle traction when one or more wheels has a tendency to spin, while others do not. It operates in conjunction with the DSC system. If a wheel is spinning, ETC automatically brakes that wheel until it regains grip. This braking activity allows the engine power to be transmitted to the remaining wheels. Some noise may be generated when the brakes are applied. Warning indicator A fault with the ETC system is indicated by illumination of the amber DSC warning indicator. This could also indicate that the DSC has been manually deactivated, see INDICATOR GROUPING, 108. If the indicator illuminates constantly, and does not extinguish when the DSC lever is pressed, a fault has been detected in the system. Any fault will deactivate ETC. Drive with care and seek qualified assistance as soon as possible.
Hill Descent Control 200 L Hill Descent Control HILL DESCENT CONTROL* Hill Descent Control (HDC) operates in conjunction with the anti-lock braking system to provide greater control in off-road situations particularly when descending severe gradients. HDC may be used in ’D’, ’R’ and CommandShift ’1’ in HIGH range and in ’D’, ’R’ and all CommandShift gears in LOW range. When in ’D’, the vehicle will automatically select the most appropriate gear. The vehicle should not be driven with the HDC active in ’N’ neutral. Note: If Terrain Response is fitted, some of its program/range combinations will activate HDC automatically. HDC can be selected at speeds below 80 km/h (50 mph). Once the vehicle speed reduces below 50 km/h (30 mph), the green lamp will illuminate continuously, and full HDC function will be active. If the vehicle speed exceeds 80 km/h (50 mph), HDC will deselect and the green HDC indicator will extinguish. If HDC is already selected and vehicle speed rises above 50 km/h (30 mph) in HIGH range, HDC function is suspended and the green HDC indicator will flash. A message will also appear in the message display center.To select HDC Press and release the switch (arrowed) to select HDC. Press and release again to deselect. The green information indicator will extinguish. If HDC is deselected when HDC is operating, the system ’fades out’, allowing the vehicle to gradually increase in speed. When used in LOW range, HDC controls the vehicle speed more aggressively. Use LOW range gears when steep descents are to be attempted. Note: HDC is automatically deselected if the vehicle ignition is switched off for more than 6 hours. H5606L
