OWNER MAINTENANCE
In addition to the routine services and 
inspections referred to previously, a number of 
simple checks must be carried out more 
frequently. You can carry out these checks 
yourself and advice is given on the pages that 
follow.
Any significant or sudden drop in fluid levels, 
or uneven tyre wear, should be reported to a 
dealer without delay.
Daily checks
•Operation of lights, horn, direction 
indicators, wipers, washers and warning 
lights.
•Operation of seat belts and brakes.
•Look for fluid deposits underneath the 
vehicle that might indicate a leak 
(condensation drips from the air 
conditioning are normal).
Weekly checks
•Engine oil level.
NOTE: The engine oil level should be 
checked more frequently if the vehicle is 
driven for prolonged periods at high speeds.
•Coolant level.
•Brake fluid level.
•Power steering fluid level.
•Screen washer fluid level.
•Active cornering enhancement fluid level
•Tyre pressures and condition.
•Operate air conditioning.
All fluid specifications and capacities are shown 
in ‘LUBRICANTS AND FLUIDS’, page 221.
WARNING
If brake pedal travel is unusually long or if 
there is any significant loss of brake fluid, 
contact your dealer immediately. Driving 
under such conditions could result in 
extended stopping distances or complete 
brake failure.
IMPORTANT INFORMATION
Special operation conditions
When a vehicle is operated in extremely 
arduous conditions or a dusty, wet or 
muddy terrain, more frequent attention 
must be paid to servicing requirements.
For example: if your vehicle experiences 
deep wading conditions, even DAILY 
servicing could be necessary to ensure the 
continued safe and reliable operation of the 
vehicle.
Contact a Land Rover dealer for advice.

SAFETY IN THE GARAGE
WARNING
Cooling fans may continue to operate after the 
engine is switched off. When the engine is 
hot, the cooling fans may also COMMENCE 
operating after the engine is switched off and 
continue operating for up to 10 minutes. To 
avoid injury, keep clear of all fans and 
remove any loose clothing while working in 
the engine compartment.
Whenever you need to carry out maintenance 
on your vehicle, observe the following safety 
precautions at all times:
•Keep your hands, hair, tools and clothing 
away from drive belts and pulleys.
•If the vehicle has been driven recently, DO 
NOT TOUCH exhaust and cooling system 
components until the engine has cooled.
•DO NOT TOUCH electrical leads or 
components while the engine is running, 
or with the starter switch turned on.
•NEVER leave the engine running in an 
unventilated area - exhaust gases are 
poisonous and extremely dangerous.
•DO NOT work beneath the vehicle with the 
wheel changing jack as the only means of 
support.
•Ensure sparks and naked lights are kept 
away from the engine compartment.
•Wear protective clothing, including, 
where practicable, gloves made from an 
impervious material.
•Remove metal wrist bands and jewellery 
before working in the engine 
compartment.
•DO NOT allow tools or metal parts of the 
vehicle to make contact with the battery 
leads or terminals.
WARNING
Under no circumstances should any part of 
the fuel system be dismantled or replaced by 
anyone other than a suitably qualified motor 
vehicle technician. Failure to comply with this 
instruction may result in fuel spillage with a 
consequent serious risk of fire.
Poisonous fluids
Fluids used in motor vehicles are poisonous 
and should not be consumed or brought into 
contact with open wounds. These include 
battery acid, anti-freeze, brake and power 
steering fluid, petrol, engine oil and windscreen 
washer additives. 
For your own safety, ALWAYS read and obey all 
instructions printed on labels and containers.
Used engine oil
Prolonged contact with engine oil may cause 
serious skin disorders, including dermatitis and 
cancer of the skin. ALWAYS wash thoroughly 
after contact.
It is illegal to pollute drains, water courses 
or soil with toxic chemicals such as used 
engine oil. Use authorised waste disposal sites 
to dispose of used oil and toxic chemicals.

EMISSION CONTROL
Your vehicle is fitted with various items of 
emission and evaporative control equipment 
designed to meet specific territorial 
requirements. You should be aware that 
unauthorised replacement, modification or 
tampering with this equipment by an owner or 
repair shop may be unlawful and subject to 
legal penalties.
In addition, engine settings must not be 
tampered with. These have been established to 
ensure that your vehicle complies with 
stringent exhaust emission regulations. 
Incorrect engine settings may adversely affect 
exhaust emissions, engine performance and 
fuel consumption, as well as causing high 
temperatures, which will result in damage to 
the catalytic converter and the vehicle.
NOTE: While Land Rover North America Inc. 
maintains that an authorised Land Rover dealer 
is best equipped to carry out repairs and 
maintenance on the emission control system, 
such work may be carried out by any competent 
automotive repair shop or individual using 
certified parts.
ROAD TESTING ON DYNAMOMETERS 
(‘rolling roads’)
Because your vehicle is equipped with anti-lock 
brakes and permanent four-wheel drive, it is 
essential that any dynamometer testing is 
carried out ONLY by a qualified person familiar 
with the dynamometer testing and safety 
procedures practiced by Land Rover dealers. 
Contact your Land Rover dealer for further         
information.

E ngine  OilCHECK & TOP-UP
Check the oil level at least every 250 miles 
(400 km) when the engine is COLD and with the 
vehicle resting on level ground.
NOTE: If it is necessary to check the oil level 
when the engine is hot, switch off the engine 
and let the vehicle stand for five minutes to 
allow the oil to drain back into the sump. DO 
NOT start the engine.
As a general guide, if the level on the dipstick:
•is nearer to the upper mark than the lower, 
add no oil.
•is nearer to the lower mark than the upper, 
add half a US quart (0.5 litre) of oil. 
•is below the lower mark, add one US quart 
(1 litre) of oil and re-check the level after a 
further five minutes.
1.Withdraw the dipstick and wipe the blade 
clean.
2.Fully re-insert the dipstick and withdraw 
again to check the level, which should 
NEVER be allowed to fall below the lower 
mark on the dipstick.
3.To top-up, unscrew the oil filler cap and 
add oil to maintain the level between the 
UPPER and LOWER marks on the dipstick.
DO NOT OVERFILL!
Oil specification
It is essential to use an oil suitable for the 
climatic conditions in which the vehicle is to be 
operated. Precise specifications are shown in 
‘LUBRICANTS AND FLUIDS’, page 221. If in 
doubt, contact your Land Rover dealer.

DRAIN & REFILL
Ensure the engine oil is changed at the 
recommended service intervals as specified in 
the Passport to Service book.
NOTE: Under severe operating conditions (i.e. 
regular use in muddy terrain or dusty 
conditions), the engine oil must be changed 
more frequently, even to the extent of a daily 
change. Consult your Land Rover dealer for 
guidance.
Used engine oil
WARNING
Prolonged contact with used engine oil can 
cause serious skin disorders, including 
dermatitis and cancer of the skin. Wear 
protective clothing if possible and ALWAYS 
wash thoroughly after contact.
It is illegal to pollute drains, water courses 
or soil with toxic chemicals such as used 
engine oil. Use authorised waste disposal sites 
to dispose of used oil and toxic chemicals.Drain
With the engine warm (to assist oil drainage) 
and the vehicle parked on firm, level ground, 
remove the filler cap and position a container of 
suitable size (at least 6.90 US quarts or 6.60 
litres) under the drain plug, in the bottom of the 
sump. 
Remove the drain plug and copper washer and 
allow the engine oil to drain into the container.
WARNING
Oil from the engine can be very hot, to avoid 
harmful burns, take care when removing the 
drain plug.

Refill
Clean the oil drain plug and its mating surface 
on the engine sump. Fit the drain plug, 
complete with a new copper washer and tighten 
to 24 lbf.ft (33 Nm).
Refill the engine with fresh oil, suitable for the 
climatic conditions in which the vehicle is to be 
operated (see ‘LUBRICANTS AND FLUIDS’, 
page 221).
DO NOT overfill the engine! Remember that a 
little oil will always remain in the engine after 
draining and that, therefore, the quantity of oil 
required to refill the engine will be slightly less 
than the full capacity quoted in ‘CAPACITIES’, 
page 223.
After filling, allow a few minutes to elapse 
before checking the level on the dipstick (this 
will allow all the oil to drain into the sump and 
enable a true reading to be obtained). Once the 
correct level of oil is shown on the dipstick, 
replace the filler cap.
Start and run the engine. Do not rev the engine 
until the oil pressure warning light 
extinguishes. Check for oil leaks around the 
drain plug.
Stop the engine, wait a few minutes, then check 
the oil level and top up if necessary.Oil filter renewal
NOTE: To avoid draining the oil pump, it is 
essential that the engine is filled with oil to the 
correct level, before the filter is removed. It is 
therefore recommended that the engine oil is 
renewed before work on the filter commences.
1.Clean the area around the filter head and 
place a suitable container beneath the 
engine.
2.Using a strap spanner, or similar tool, 
unscrew the filter anti-clockwise and 
discard it. 
3.Smear the seal of the new filter with clean 
engine oil, partially fill the filter with oil and 
then screw the filter on clockwise, until it 
is securely is position. Use hand force 
only, DO NOT overtighten.
4.Start and run the engine. Do not rev the 
engine until the oil pressure warning light 
extinguishes. Check for oil leaks around 
the filter and drain plug.
5.Stop the engine, wait a few minutes, then 
check the oil level and top up if necessary.

Air CleanerELEMENT RENEWAL
Renewing the air cleaner element at the 
recommended service intervals (see your 
‘Passport to Service book’), is extremely 
important. However, to maintain optimum 
engine performance under dusty operating 
conditions, more frequent renewal will be 
necessary. Consult your dealer for guidance.
Release the two catches securing the hose to 
the rear of the air cleaner, then detach the hose. 
Release the catches securing the cover to the 
air cleaner body, disengage the two clips at the 
front of the air cleaner and remove the cover to 
gain access to the element.
Remove and discard the air cleaner element. 
Before fitting a new element, clean the inside of 
the air cleaner body and cover.Fit the new air cleaner element and cover and 
secure catches. Ensure the two clips at the front 
of the air cleaner are properly engaged.
Connect the hose to the rear of the air cleaner 
and secure catches.
H2658A
IMPORTANT INFORMATION
Always fit a NEW element; under no 
circumstances should a contaminated 
element be cleaned and used again. 
						

							Spark Plugs
169
S park PlugsSPARK PLUG REMOVE & REFIT
Spark plug removal
Remove the plug leads, ensuring that you hold 
the rubber shroud and NOT the high tension 
leads (this will ensure no damage occurring to 
the connectors during removal).
Ensure that the recesses around the plugs are 
free from debris (to avoid foreign matter 
accidentally entering the cylinder head) and use 
a suitable spark plug wrench to remove the 
plugs and washers.
Refitting the plugs
When refitting, take care not to cross-thread the 
spark plugs, otherwise costly damage to the 
cylinder head will result.
Only fit plugs of a type recommended by the 
vehicle manufacturer (see ‘ENGINES’, 
page 224) and tighten to a torque of 15 lbf.ft 
(20 Nm). Please note that incorrect grades of 
plug may lead to engine failure and serious 
damage.Refitting the high tension (H.T.) leads
To ensure the correct firing order (1, 8, 4, 3, 6, 
5, 7, 2), the high tension leads must be replaced 
in the correct relationship to each other (as 
illustrated). Failure to maintain the correct plug 
lead connections, will result in a misfire and 
possible damage to the catalytic converter.
When pushing the leads onto the plugs, ensure 
that the shrouds are firmly seated on the plugs.
