Fluid top-up
WARNING
Fluid is highly toxic and can be fatal if 
swallowed - keep containers sealed and out 
of reach of children. If accidental 
consumption of fluid is suspected, seek 
medical attention immediately.
If fluid should come into contact with the skin 
or eyes, rinse immediately with plenty of 
water.
Do not spill fluid onto a hot engine - a fire may 
result.
NOTE: Fluid will damage painted surfaces; soak 
up any spillage with an absorbent cloth 
immediately and wash the area with a mixture 
of car shampoo and water.Check and Top-up
Check the fluid level against the level marks on 
the side of the reservoir. If more fluid is needed, 
first wipe the filler cap clean to prevent dirt from 
entering the reservoir, then twist the cap a 
quarter turn anti-clockwise and pull to remove. 
Top up the reservoir until the fluid reaches the 
upper level mark. DO NOT OVERFILL!
Any large or sudden drop in the fluid level 
must be investigated by a qualified dealer.
NOTE: While the power steering and active 
cornering enhancement systems share the 
same fluid specification and reservoir, both 
systems are entirely independent of each other. 
The reservoir is divided into two compartments 
and each system has its own filler cap.

WashersWINDSCREEN WASHER TOP-UP
The windscreen washer reservoir supplies both 
front and rear screen washer jets and headlight 
washer jets.
Check the reservoir level at least every week 
and top-up with a mixture of water and 
screenwash solvent. Preferably mix the 
recommended quantities of water and 
screenwash in a separate container before 
topping-up, and always follow the instructions 
on the container. 
Operate the washer switches periodically to 
check that the nozzles are clear and properly 
directed.
WARNING
If you operate your vehicle in temperatures 
below 40 degrees F, use washer fluid with 
anti-freeze protection. In cold weather, 
failure to use washer fluid with anti-freeze 
protection could result in impaired 
windshield vision and increase the risk of a 
vehicle crash.
WARNING
Some screenwash products are inflammable, 
particularly if high or undiluted 
concentrations are exposed to sparking. DO 
NOT allow screenwash to come into contact 
with naked flames or sources of ignition. 
NOTE: DO NOT use an anti-freeze or 
vinegar/water solution in the washer reservoir - 
anti-freeze will damage painted surfaces, whilst 
vinegar can damage the windscreen washer 
pump.
NOTE: Body panels may suffer discolorization 
as a result of screenwash spillage. Take care to 
avoid spillage, particularly if an undiluted high 
concentration is being used. If spillage occurs, 
wash the affected area immediately with water.
WARNING
Do not put engine coolant in the windscreen 
washer fluid reservoir. If engine coolant is 
sprayed onto the windscreen, it could make it 
difficult to see through the windscreen.
WASHER JETS
The windscreen washer jets are set during 
manufacture and should not need adjusting. 
However, if adjustment is ever necessary, 
insert a needle into the jet orifice and lever 
gently to position each jet so that the spray is 
directed towards the center of the windscreen.
The rear screen jets located in the wiper arm are 
not adjustable.
Should any jet become obstructed, insert a 
needle or thin strand of wire into the orifice to 
clear the blockage.
HEADLIGHT WASHERS
The spray jets are set during manufacture and 
should not need to be adjusted.

Wiper BladesWIPER BLADE REPLACEMENT
Front wiper blades
Lift the wiper arm away from the windscreen. 
Disconnect the blade by pushing the locking tab 
(see inset in illustration) to the unlock position 
and slide upward.
Fitting a replacement blade is a reversal of this 
process. Check that the blade is securely locked 
before returning the wiper assembly to the 
windscreen.
Only fit replacement wiper blades that are 
identical to the original specification.
Grease, silicone and petrol based products 
impair the blades wiping capability. Wash the 
wiper blades in warm soapy water and 
periodically check their condition.
If signs of hardness or cracking in the rubber 
are found, or if the wipers leave streaks or 
unwiped areas on the windscreen during use, 
then the wiper blades should be replaced.
Clean the windscreen regularly with an 
approved glass cleaner and ensure the screen is 
thoroughly cleaned before fitting replacement 
wiper blades.Rear wiper blades
With the spare wheel removed from the 
taildoor, lift the wiper arm away from the rear 
screen. Pivot the blade assembly away from the 
arm (as arrowed), levering against resistance, 
until the two retaining lugs detach from their 
slots at the end of the arm. Carefully replace the 
arm to its stowed position.
To replace, position the wiper arm into the 
aperture in the middle of the blade assembly, 
line up the retaining lugs with the 
corresponding slots in the wiper arm and push 
firmly into position until the blade clips into 
place.

BatteryBATTERY SAFETY
WARNING
ALWAYS wear appropriate eye protection 
when working around batteries.
Batteries contain acid, which is both 
corrosive and poisonous. If spillage occurs:
•On clothing or the skin - remove any 
contaminated clothing immediately, flush 
the skin with large amounts of water, and 
seek medical attention urgently.
•In the eyes - flush with clean water 
immediately for at least 15 minutes. Seek 
medical attention urgently.
•Swallowing battery acid can be fatal 
unless IMMEDIATE action is taken - seek 
medical attention urgently.
During normal operation batteries emit 
explosive hydrogen gas - to avoid fire, ensure 
sparks and naked lights are kept away from 
the engine compartment.
For your safety remove all metal wrist bands 
and jewellery before working in the engine 
compartment and NEVER allow the battery 
terminals or vehicle leads to make contact 
with tools or metal parts of the vehicle.
WARNING
Battery posts, terminals, and related 
accessories contain lead and lead 
compounds. Wash hands after handling.
BATTERY MAINTENANCE
The battery is designed to be maintenance free, 
so topping-up is unnecessary. On the top of the 
battery there is a battery condition indicator 
(arrowed in illustration). Examine the indicator 
periodically to check the batterys condition. 
When the indicator shows:
•GREEN - the battery is in a good state of 
charge.
•DARK (turning to black) - the battery needs 
charging.
•CLEAR (or light yellow) - the battery must 
be replaced. Do not charge the battery or 
jump start the vehicle in this condition.
NOTE: When checking the battery condition 
indicator, if necessary, clean the battery top to 
ensure a clear view.
If the indicator shows clear or yellow, tap the 
indicator with the handle of a screwdriver to 
disperse any air bubbles. If the colour is 
unchanged, the battery must be replaced.

Battery removal and replacement
WARNING
ALWAYS remove the starter key before 
disconnecting the battery. Failure to do this 
could cause a failure of the airbag SRS.
To prevent a short circuit, ALWAYS 
disconnect the negative (‘-’) cable first and 
NEVER allow the battery terminals or vehicle 
leads to make contact with tools or metal 
parts of the vehicle.
Before disconnecting the battery, disarm the 
alarm, and ensure that the starter switch and all 
electrical equipment is turned off.
To remove: disconnect the negative (‘-’) cable 
first and then the positive (‘+’) cable. When 
reconnecting, connect the positive cable first 
and then the negative cable. 
To release the battery from the vehicle, undo 
the nuts securing the battery clamping plate 
and remove the clamping plate.
When replacing, ensure the battery is fitted the 
right way round (terminal posts towards the 
rear of the vehicle) and that the clamping plate 
is secure. Tighten the clamping plate nuts until 
the clamping plate is free from movement, but 
do not over tighten.Replacement batteries
Only fit a replacement battery of the same type 
and specification as the original - other 
batteries may vary in size or have different 
terminal positions which could cause a fire 
hazard when connected to the vehicles 
electrical system.
CAUTION: DO NOT reverse the polarity of the 
battery - the electrical system may be damaged 
if the battery leads are connected to the wrong 
terminals.
CAUTION: Keep the battery upright at all times 
- damage will be caused if the battery is tilted 
more than 45 degrees.
CAUTION: DO NOT run the engine with the 
battery disconnected, or disconnect the battery 
whilst the engine is running.
Battery disposal
Used batteries should be recycled. 
However, batteries are hazardous - you 
should seek advice about disposal from a Land 
Rover retailer or your local authority.

Battery charging
WARNING
Batteries generate explosive gases, contain 
corrosive acid and produce levels of electric 
current sufficient to cause serious injury. 
While charging always heed the following 
precautions:
•Before charging, disconnect and remove 
the battery from the vehicle - charging the 
battery with the cables connected may 
damage the vehicles electrical system. 
•Make sure the battery charger leads are 
securely clamped to the battery terminals 
BEFORE switching on the battery charger. 
Do not move the leads once the charger is 
switched on.
•While charging, shield your eyes or avoid 
leaning over the battery and keep the area 
around the top of the battery well 
ventilated.
•Do not allow open flame and/or 
incandescent lamps near the battery 
(batteries generate inflammable hydrogen 
during and after charging).
•If the battery is fitted with a condition 
indicator, the indicator shows GREEN 
when the battery is charged sufficiently. 
When charging is finished, switch off the 
battery charger BEFORE disconnecting the 
leads from the battery terminals. 
After charging, leave the battery for an hour 
BEFORE reconnection to the vehicle - this will 
allow time for explosive gases to disperse, 
thereby minimising the risk of fire or 
explosion.
NOTE: Be aware that a battery will take longer to 
charge in a cold environment.CAUTION: DO NOT charge the battery if it is 
connected to the vehicle - this may seriously 
damage the electrical system.
IMPORTANT INFORMATION
DO NOT attempt to charge the battery if the 
battery condition indicator is clear or light 
yellow.
DO NOT charge the battery if it is 
suspected of being frozen.

TiresCARING FOR YOUR TIRES
WARNING
DEFECTIVE TIRES ARE DANGEROUS! Do not 
drive if any tire is damaged, is excessively 
worn, or is inflated to an incorrect pressure.
ALWAYS replace worn or defective tires with 
the factory recommended specification (see 
‘WHEELS & TIRES’, page 235). Failure to do 
so may affect the safe handling of the vehicle.
Always drive with consideration for the 
condition of the tires, and regularly inspect the 
tread and side walls for any sign of distortion 
(bulges), cuts or wear.
The most common causes of tire failure are:
•Bumping against curbs
•Driving over deep potholes in the road
•Driving with under or over-inflated tires
NOTE: If possible, protect tires from 
contamination by oil, grease, fuel and other 
automotive fluids.Tire pressures
Correctly inflated tires will ensure that you 
enjoy the best combination of tire life, ride 
comfort, fuel economy and road handling.
Under-inflated tires wear more rapidly, can 
seriously affect the vehicles road handling 
characteristics and fuel consumption, as well 
as increasing the risk of tire failure. 
Over-inflated tires give a harsher ride, wear 
unevenly and are more prone to damage.
Tire pressures should be checked at least once 
a week with normal road use, but should be 
checked DAILY if the vehicle is used off-road.
Check the pressures (including the spare 
wheel) when the tires are cold - be aware that it 
only takes a mile (1.6 km) of driving to warm up 
the tires sufficiently to affect the tire pressures.
Air pressure naturally increases in warm tires; if 
it is necessary to check the tires when they are 
warm (after the vehicle has been driven for a 
while), you should expect the pressures to have 
increased between 4 and 6 lbf/in
2
(0.3 to 0.4 kgf/cm2). In this circumstance, 
NEVER let air out of the tires in order to match 
the recommended pressures.
NOTE: If the vehicle has been parked in strong 
sunlight or used in high ambient temperatures, 
DO NOT reduce tire pressures; instead, move 
the vehicle into the shade and allow the tires to 
cool before checking.
The recommended pressures for cold tires are 
shown in ‘WHEELS & TIRES’, page 235. 
						

							Tires
187
Tire wear 
Some tires fitted as original equipment have 
wear indicators moulded into the tread pattern. 
When the tread has worn down to 1.6 mm 
(1/16 inch) the indicators start appearing at the 
surface of the tread pattern, producing the 
effect of a continuous band of rubber across the 
width of the tire.
A tire MUST be replaced as soon as an indicator 
band becomes visible or the tread depth 
reaches the minimum permitted by legislation.Tread depth must be checked regularly (at 
every maintenance service, or more 
frequently). Always replace a tire before the 
tread reaches a remaining depth of 1.6 mm 
(1/16 inch). DO NOT drive with tires worn to 
this limit, the safety of the vehicle and 
occupants will be adversely affected.
NOTE: After off-road use, check to make sure 
there are no lumps or bulges in the tires or 
exposure of the ply or cord structure.
Valves
Keep the valve caps screwed down firmly - they 
prevent dirt from entering the valve. Check the 
valve for leaks (listen for a tell-tale hissing) 
when you check the tire pressure.
Punctured tires
Your vehicle is fitted with tubeless tires, which 
may not leak if penetrated by a sharp object, 
provided the object remains in the tire. If you 
are aware of this occurring, reduce speed 
immediately and drive with caution until the 
spare wheel can be fitted. 
A puncture of this kind will eventually cause the 
tire to lose pressure, which is why regular (and 
frequent) checking of tire pressures is 
important. 
WARNING
Punctured or damaged tires must be 
permanently repaired or replaced as soon as 
possible, if in doubt, see expert advice. DO 
NOT DRIVE WITH A PUNCTURED TIRE!
H2571 
						

							Tires
188
Replacement tires
Wheel rims and tires are matched to suit the 
handling characteristics of the vehicle. For 
safety, ALWAYS check that replacement tires 
comply with the original specification (see 
‘WHEELS & TIRES’, page 235) and that the load 
and speed ratings shown on the side wall are 
the same as that of the original equipment. 
Contact your Land Rover retailer for further 
information or assistance.
WARNING
ALWAYS use the same type of radial-ply tires 
front and rear. DO NOT use cross-ply tires, or 
interchange tires from front to rear.
Your vehicle is fitted with road wheels that 
will NOT accept inner tubes. DO NOT fit a 
tubed tire.
DO NOT replace wheels with any type other 
than genuine Land Rover parts. Wheels and 
tires are designed for both off-road and 
on-road use and have a very important 
influence on vehicle handling. Alternative 
wheels which do not meet original equipment 
specifications should not be fitted as they 
could affect vehicle handling.
Always have replacement wheels and tires 
balanced before use.
UNIFORM TIRE QUALITY GRADING
Quality Grades can be found where applicable 
on the tire sidewall between tread shoulder and 
maximum section width. For example:
Tires that are deep tread, winter-type snow tires 
are exempt from the marking requirements as 
described above. Consequently, the tires fitted 
to your vehicle may not carry these markings.
All passenger car tires must conform to Federal 
Safety Requirements in addition to these 
grades.
Treadwear
The treadwear grade is a comparative rating 
based on the wear rate of the tire when tested 
under controlled conditions on a specified 
government test course. For example; a tire 
graded 150 would wear one and one-half (1½)
times as well on the government course as a 
tire graded 100. The relative performance of 
tires depends upon the actual conditions of 
their use however, and may depart significantly 
from the norm due to variations in driving 
habits, service practices and differences in road 
characteristics and climate. 
Treadwear 200 Traction AA Temperature A 
						

							Tires
189
Traction
The traction grades, from highest to lowest, are 
AA, A, B and C. The grades represent a tires 
ability to stop on wet pavement as measured 
under controlled conditions on specified 
government test surfaces of asphalt and 
concrete. A tire marked C may have poor 
traction performance. 
WARNING
The traction grade assigned to this tire is 
based on straight-ahead braking traction 
tests, and does not include acceleration, 
cornering, hydroplaning, or peak traction 
characteristics.
Temperature
The temperature grades A (the highest), B, and 
C, represent a tires resistance to the generation 
of heat and its ability to dissipate heat when 
tested under controlled conditions on a 
specified indoor laboratory test wheel. 
Sustained high temperatures can cause the 
material of a tire to degenerate and reduce tire 
life, and excessive temperature can lead to 
sudden tire failure.
The grade C corresponds to a level of 
performance which all passenger car tires must 
meet under the Federal Motor Safety Standard 
No 109.
Grades B and A represent higher levels of 
performance on the laboratory test wheel than 
the minimum required by law. 
WARNING
The temperature grade for this tire is 
established for a tire that is properly inflated 
and not overloaded. Excessive speed, 
underinflation, or excessive loading, either 
separately or in combination can cause heat 
buildup and possible tire failure.
SNOW CHAINS
Snow chains are designed for use on roads in 
extreme conditions only, and are not 
recommended for off-road use. If it is 
necessary to fit snow chains to your vehicle, 
ALWAYS observe the following:
•Snow chains must ONLY be fitted to the rear 
wheels of the vehicle, provided the wheels 
and tires conform to one of the original 
equipment specifications listed in the 
handbook (see ‘WHEELS & TIRES’, 
page 235).
•ONLY Land Rover approved chains should 
be used - these are designed for your 
vehicle and will eliminate any risk of damage 
to the vehicle.
•Always adhere to the snow chain fitting and 
retensioning instructions and the speed 
limitations recommended for varying road 
conditions. NEVER exceed 30 mph 
(50 km/h).
•Avoid tire damage by removing the chains a 
soon as the road is free from snow.
For further information about approved snow 
chains, consult your Land Rover retailer.
WARNING
DO NOT fit unapproved snow chains to the 
rear wheels - this could damage brake 
components, and seriously affect the 
vehicles ability to stop, potentially resulting 
in occupant or third party injury.
DO NOT fit snow chains to the front wheels; 
this could damage brake components.
