Starting & Driving 110 Breaking-in Proper breaking-in will have a direct bearing on the reliability and smooth running of your vehicle throughout its life. In particular, the engine, gearbox, brakes and tires need time to ‘bed-in’ and adjust to the demands of everyday motoring. During the first 500 miles (800 km), it is essential to drive with consideration for the running-in process and heed the following advice: •LIMIT maximum road speed to 70 mph (110 km/h) or 3,000 rev/min. Initially, drive the vehicle on a light throttle and only increase engine speeds gradually once the breaking-in distance has been completed. •DO NOT operate at full throttle or allow the engine to labor in any gear. •AVOID fast acceleration and heavy braking except in emergencies. Power assisted steering The hydraulic power-assisted is progressively geared; when steering straight ahead gearing is relatively low, but becomes progressively higher as the steering wheel is turned. NOTE: Power assistance is dependent on the engine running. If the engine is not running, greater effort will be required to steer the vehicle.FUEL ECONOMY Fuel consumption is influenced by two major factors: •How your vehicle is maintained. •How you drive your vehicle. To obtain optimum fuel economy, it is essential that your vehicle is maintained in accordance with the manufacturers service schedule. Items such as the condition of the air cleaner element, tire pressures and wheel alignment will have a significant effect on fuel consumption. But, above all, the way in which you drive is most important. The following hints may help you to obtain better value from your motoring: •Avoid unnecessary, short, start-stop journeys. •Avoid fast starts by accelerating gently and smoothly from rest. •Do not drive in the lower gears for longer than necessary. •Decelerate gently and avoid sudden and heavy braking. •Anticipate obstructions and adjust your speed accordingly well in advance. •When stationary in traffic, select neutral to improve fuel economy and air conditioning performance.
Starting & Driving 111 AUXILIARY EQUIPMENT CAUTION: DO NOT use auxiliary equipment, such as roller generators that are driven by one wheel of the vehicle, as they could cause failure of the gearbox differential. The vehicle will also drive itself forward through ETC action. Some local jurisdictions require emission testing using a two wheel roller dynamometer. Your vehicle is equipped with permanent 4-wheel drive and cannot be safely operated on these machines. For more information regarding safe emission testing of your vehicle consult your local Land Rover retailer. EMISSION CONTROL SYSTEM WARNING Exhaust fumes contain poisonous substances which can cause unconsciousness and may even be fatal. •DO NOT inhale exhaust gases. •DO NOT start or leave the engine running in an enclosed unventilated area, or drive with the taildoor open. •DO NOT modify the exhaust system from the original design. •ALWAYS repair exhaust system leaks immediately. •If you think exhaust fumes are entering the vehicle, have the cause determined and corrected immediately. Land Rover vehicles are fitted with emission and evaporative control equipment necessary to meet a number of territorial requirements. In some juridictions, it is against the law for vehicle owners to modify or tamper with emission control equipment, or to sanction the unauthorised replacement or modification of this equipment. In such cases, the vehicle owner and the repairer may both be liable for legal penalties. It is important to remember that all Land Rover retailers are properly equipped to perform repairs and to maintain the emission control system on your Discovery.
Catalytic Converter 112 Catalytic Con verterCATALYTIC CONVERTER The exhaust system incorporates a catalytic converter, which converts poisonous exhaust emissions from the engine into environmentally less harmful gases. CAUTION: Catalytic converters can be easily damaged through improper use, particularly if the wrong fuel is used, or if an engine misfire occurs. For this reason it is VERY IMPORTANT that you heed the precautions which follow. Fuel ONLY use fuel recommended for your vehicle. Misfire A misfire can cause an engine to run rough or skip for more than just a few seconds. If a misfire is suspected, there is a risk of catalyst damage; consult a Land Rover retailer for assistance. Starting the engine •DO NOT continue to operate the starter after a few failed attempts (unburnt fuel may be drawn into the exhaust system, thereby poisoning the catalyst) - seek qualified assistance. •Do not attempt to push or tow-start the vehicle.Driving •If a misfire is suspected, the ‘SERVICE ENGINE SOON’ warning light is flashing, or the vehicle lacks power while driving, avoid high speeds and seek immediate assistance from your Land Rover retailer. •NEVER allow the vehicle to run out of fuel (the resultant misfire could damage the catalyst). •Engines burning excessive oil (e.g. 1 quart every 750 miles) will progressively reduce catalyst efficiency. In extreme cases, blue smoke may be emitted from the exhaust. •On rough terrain, do not allow the underside of the vehicle to be subjected to heavy impacts which could damage the catalytic converter. •DO NOT overload or excessively ‘rev’ the engine. •DO NOT switch off the engine when the vehicle is in motion with a drive gear selected. WARNING Exhaust system temperatures can be extremely high - DO NOT park on ground where combustible materials such as dry grass or leaves could come into contact with the exhaust system - in dry weather a fire could result.
Catalytic Converter 113 Vehicle maintenance •Any engine misfire which causes the ‘Service engine soon’ warning light to flash (see ‘WARNING LIGHTS’, page 64), loss of engine performance or engine run-on, could seriously damage the catalytic converter. For this reason, it is vital that unqualified persons do not tamper with the engine, and that regular systematic maintenance is carried out by a Land Rover retailer. •DO NOT run the engine with a spark plug or HT lead removed, or use any device that requires an insert into a spark plug.
Fuel Filling 114 Fuel FillingLOCKING AND UNLOCKING THE FUEL FILLER FLAP WARNING To reduce the risk of any sudden discharge of fuel caused by excessive air pressure, the cap is designed to allow the fuel tank to vent during the first half turn. DO NOT fully remove the cap until any pressure has been released. Take careful note of warning labels located around the filler flap. The fuel filler is located in the rear right-hand wing. With the starter switch turned off, press the binnacle mounted switch (shown in illustration) to release the filler flap. The filler cap is designed to allow the fuel tank to vent during the first half turn. Carefully loosen the cap one half turn until resistance is felt, and allow fuel tank pressure to be released. Once the pressure is released (hissing has stopped), it is safe to fully remove the filler cap.When replacing, tighten the cap clockwise until you hear the fuel cap ratchet click at least three times. If the cap is not fitted correctly, the ‘Service engine soon’ warning light may illuminate.

Fuel Filling 115 TYPE OF FUEL Octane requirements Premium unleaded gasoline with a CLC or AKI octane rating of 90 or 92 should be used. NOTE: Federal law requires that gasoline octane ratings be posted on the pumps. The Cost of Living Council (CLC) octane rating or Anti Knock Index (AKI) octane rating shown is an average of Research Octane Number (RON) and Motor Octane Number (MON). Using unleaded fuel with an octane rating lower than that recommended, can cause persistent, heavy ‘engine knock’ (a metallic rapping noise). If severe, this can lead to engine damage. If heavy engine knock is detected when using the recommended octane rated fuel, or if steady engine knocking is present while maintaining a steady speed on level roads, contact your retailer for advice.NOTE: An occasional, light, engine knock while accelerating or climbing hills is acceptable. Octane enhancers The use of octane enhancers is not recommended, and may invalidate the vehicle warranty. NOTE: Reformulated gasolines and gasolines that contain detergents, anti-corrosion and stability additives are recommended - they will help your vehicle maintain the correct level of emissions and engine performance. Driveability If you encounter driveability, starting and stalling problems, especially in high ambient temperatures or at high altitude when the engine is cold, it may be caused by poor quality fuel. Try an alternative brand, and if the problem persists, seek advice from your retailer. Gasoline/oxygenated fuel blends To avoid invalidating the vehicle warranty, use ONLY fuels blended within the following limits: •Up to 15% of Methyl Tertiary Butyl Ether (MTBE) and unleaded fuel mix. •Up to 15% of Ethyl Tertiary Butyl Ether (ETBE) and unleaded fuel mix. •Up to 10% of Ethanol (Ethyl or grain alcohol) and unleaded fuel mix. Methanol/unleaded fuel blends In some areas, it is possible to buy unleaded fuel that is blended with up to 5% Methanol (Methyl or wood alcohol) and cosolvents and corrosion preventatives. Using these blends can cause driveability problems and damage to the fuel system components. Their use may also invalidate the vehicle warranty. WHEREVER POSSIBLE, AVOID USING FUEL CONTAINING METHANOL! IMPORTANT INFORMATION ONLY USE UNLEADED FUEL •Unleaded fuel is essential for proper operation of the emission control system. DO NOT use leaded fuel! Your engine is designed to use unleaded fuel ONLY. •Even a very small quantity of leaded fuel will damage your vehicles emission control system and could invalidate the emissions warranty. In addition, leaded fuel will damage the oxygen sensors in the fuel injection system and also seriously damage the catalyst in the catalytic converter. Fuel system cleaning agents should be avoided, as many of these products can be harmful to gaskets and other materials used in fuel system components.
Fuel Filling 116 WARNING Automotive fuels can cause serious injury, and even death if misused. Methanol/unleaded fuel blends, even in small amounts, can cause blindness and possible death if swallowed. Additionally, take precautions to prevent methanol from coming into contact with the skin. GAS STATION SAFETY WARNING Petroleum gases are highly inflammable and, in confined spaces, are also extremely explosive. Always place portable gasoline containers on the ground while filling. A fire may result if gasoline is pumped into a container that is inside a vehicle or on a truck bed. You could be burned! Always take sensible precautions when refuelling: •Switch off the engine. •Do not smoke or introduce other ignition sources. •Switch off mobile phones. •Take care not to spill fuel. •Do not overfill the tank. •Do not fill gas cans in the vehicle. •Do not get back into your vehicle during refuelling. •Use only the hold-open latch provided on the gasoline pump. Never jam the latch open with some other object. FUEL FILLING Gas station pumps are equipped with automatic cut-off sensing to avoid fuel spillage. Fill the tank SLOWLY until the filler nozzle automatically cuts-off the supply. DO NOT attempt to fill the tank beyond this point or spillage could result due to expansion of the fuel. The reduced diameter filler neck, accepts ONLY a narrow filler nozzle of the type found on pumps that supply UNLEADED fuel. NOTE: Ensure the filler cap is fitted correctly after refuelling, otherwise the ‘Service engine soon’ warning light may illuminate. EMPTY FUEL TANK IMPORTANT INFORMATION DO NOT run the fuel tank dry! •Running the fuel tank dry could create an engine misfire capable of damaging the catalytic converter. It will also cause the ‘Service engine soon’ warning light to illuminate.
Fuel Filling 117 FUEL CUT-OFF SWITCH The fuel cut-off switch is a safety device which, in the event of a collision or sudden impact, automatically cuts off the fuel supply to the engine. The switch is located on the engine compartment bulkhead. After an impact, the switch must be reset by pressing the rubber top (arrowed in illustration) before the engine can be restarted. WARNING ALWAYS check for fuel leaks before resetting the switch! Activating the switch when the fuel system has been damaged (evidenced by fuel leakage or odor) will cause additional fuel leakage increasing the risk of fire. H4406
Automatic Transmission 118 Au to matic Tran smissionGEAR SELECTOR The Automatic transmission features a four speed main gearbox with a torque converter and a two speed transfer box. Using the main gearbox in conjunction with the transfer gearing produces eight forward and two reverse speeds. Main gearbox selector lever A spring loaded catch restricts movement of the lever, thereby preventing inadvertent gear selection. Press and hold the trigger mounted in the handle of the selector lever (arrowed in illustration) to release the catch whilst moving the lever to the required position. NOTE: Gear selection between ‘D’ and ‘3’ in high and low range may be made without operating the trigger.Selector lever positions •‘P’ Park In this position, the transmission is locked to prevent the vehicle from rolling away. Select ONLY when the vehicle is stationary and with the handbrake applied. •‘R’ Reverse Select ONLY when the vehicle is stationary. •‘N’ Neutral Use this position when the vehicle is stationary and the engine is to idle for a short period (at traffic lights, for example). •‘D’ Drive In high range, select for all normal driving on good road surfaces; fully automatic gear changing occurs on all four forward gears according to vehicle speed and accelerator position. •‘3’ (1st, 2nd and 3rd gears) Automatic gear changing is limited to first, second and third gears only. In high range, use this position in congested traffic conditions and for town driving. •‘2’ (1st and 2nd gears) Automatic gear changing is limited to first and second ratios only. In high range, use when driving up steep gradients and for negotiating very narrow, twisting, roads. This position also provides moderate engine braking for descending slopes. •‘1’ (1st gear only) Use on very severe gradients, particularly when towing, and when maximum engine braking is required. WARNING To reduce the risk of inadvertent vehicle movement when parked, always leave the vehicle with the gear selector in ‘P’ (Park) position, as well as applying the handbrake. H2640 MODE
Automatic Transmission 119 Starting and driving Drivers unfamiliar with the performance characteristics of an automatic gearbox should thoroughly familiarize themselves with the following instructions before driving. •Before starting the engine, ensure that both foot and parking brakes are applied. •After starting the engine, KEEP BOTH BRAKES APPLIED before and whilst moving the selector lever to the required drive position. •Keep the brakes applied until you are ready to move - remember, once a drive position is selected, an ‘automatic’ will tend to creep forward (or backward) without throttle application, as soon as the brakes are released. •Never ‘rev’ the engine while selecting a forward or reverse drive gear, or while the vehicle is stationary with a drive gear selected - remember, an ‘automatic’ will move immediately once the accelerator pedal is pressed. NOTE: The starter key cannot be removed unless the gear selector is in ‘P’ (Park), and it is impossible to move the selector lever from ‘P’ (Park) unless the foot brake is pressed. Gear change speeds With ‘D’ selected, the road speeds at which gear changes take place will vary according to the position of the accelerator: minimum acceleration will result in gear changes at low road speed, while larger throttle openings will cause the gearbox to delay gear changes until faster road speeds have been reached (thereby increasing acceleration). With practice, gear changes can be made to occur at a wide range of road speeds depending on accelerator pedal pressure.On long inclines the gearbox will sometimes change back and forth between gears. This occurs because the transmission does not include a ratio that is precisely right for the particular incline and vehicle loading circumstances. However, excessive gear changing results in a loss of momentum and is wasteful of fuel. It can be prevented by selecting the ‘3’ or ‘2’ positions which limit the gearbox to lower ratios. ‘Kick-down’ To provide rapid acceleration for overtaking, push the accelerator pedal to the full extent of its travel in a single quick movement (this is known as ‘kick-down’). Up to a certain speed, this will cause an immediate downshift into the lowest appropriate gear, followed by rapid acceleration. Once the pedal is relaxed, normal gear change speeds will resume (dependent upon road speed and accelerator pedal position).
