Vehicle care

CLEANING THE ALLOY WHEELS
Wash the wheels with soap and water, this
should be done more frequently when the
wheels are exposed to heavy dirt deposits, salt,
clay etc. If you are unsure how often to clean
the wheels in particular conditions, seek advice
from your Dealer/A uthorised Repairer.
Jaguar approved wheel cleaner should be used
to remove heavy soiling.
CLEANING THE EXTERIOR
Washing the vehicle paintwork
Remove heavy deposits of mud and dirt with a
hose before washing the vehicle.
When salt is used on the roads, wash the
vehicle immediately after encountering such
conditions. Clean undersid es and wheel arches
using a high pressure jet.
Wash the vehicle frequently using a sponge
and generous quantities of cold or luke warm
water containing a suitable car shampoo. Rinse
thoroughly and dry with a chamois leather or
synthetic substitute.
For best results, do not wash the vehicle under
strong sunlight. Always allow the vehicle to
cool down before washing.
Do not use a dry cloth to wipe dirty paintwork.
Dust and gritty substances are abrasive and
will scratch the paintwork. Remove dirt using a
cellulose sponge and plen ty of warm (never
hot) water. Rinse off with clean water and dry
using a clean, damp cham ois leather. Wash the
vehicle frequently.
CAUTION
Do not use non-approved, or acid based
wheel cleaners. These can damage the
wheel coating which may lead to corrosion of
the wheel rims.
CAUTIONS
Some high pressure cleaning systems
are sufficiently powe rful to penetrate
door and window seals, and damage trim and
door locks. Never aim the water jet directly at
the engine air intake, he ater air intakes, body
seals (doors, sunroof, windows etc.) or at any
components which may be damaged (lamps,
mirrors, exterior trim etc.).
Ensure that you read and comply with all
warnings and instruct ions supplied with
any cleaning products.
Never use cleaning products which are
not approved for use on vehicles.
CAUTION
Substances which are corrosive, such
as bird droppings, tree resin, dead
insects, tar spots, road salt and industrial fall
out, can damage the vehic le's paintwork. Any
such deposits should be removed as soon as
possible to prevent damage.

Do not use household soaps or detergents. The
use of Jaguar Vehicle Shampoo is
recommended.
Note: The vehicle's brightwork should be
cleaned using a sponge and generous
quantities of cold or lukewarm water only.
Rinse thoroughly and dry with a chamois
leather or synthetic substitute.
Using an automatic wash
Note: Regular use of automatic car washes
tends to dull the lustre of the paintwork.
1. Drive up to the entry of the car wash and
onto the conveyor.
2. Select N (Neutral) using the JaguarDrive
selector.
3. Press and release the engine START/STOP
button to stop the engine. The JaguarDrive
selector should remain raised and the
selector and message centre should
indicate that N is selected. 4.
The vehicle should rema in in this condition
while it is conveyed through the car wash.
5. At the end of the wash cycle, when directed
to start the engine by the car wash
instructions, press the brake pedal and
press and release the engine START/STOP
button to start the engine.
6. Select D (Drive) using the JaguarDrive
selector and drive away.
Do not start the engine or change the
JaguarDrive selector position during the car
wash.
After leaving the car wash, switch on the
windscreen wiper immediately to remove water
and prevent a build up of wax.
Underbonnet cleaning
CAUTIONS
Commercially operated automatic car
washes, jet washes and power-operated
mops, are not recommen ded. The detergents
used can contain certain chemicals which
may, over time, be detrimental to some
exterior parts of the vehicle. Prolonged usage
of automatic car wash es and power-operated
mops will also cause fine scratches in the paint
surface.
Ensure that Auto wipe is not selected
when entering a car wash, or damage to
the wiper blades and arms can occur if they
operate during the wash cycle.
Ensure that when using an automatic
drive through car wash, N (Neutral) is
selected and that the ignition is left in
convenience mode for the duration of the
wash.
CAUTIONS
Do not use a high pr essure washer or
steam cleaner in the engine
compartment. Damage to components could
occur.
Ensure that the brake fluid reservoir is
kept dry at all times. Only use a clean,
dry cloth to clean the brake fluid cap and
reservoir.

petrol engines is checked automatically at all
times by the electronic dipstick.
Severe driving conditions
When a vehicle is operated in severe
conditions, more frequent attention must be
paid to servicing requirements.
Severe driving conditions include:
• Driving in dusty and/or sandy conditions.
• Driving on rough and/or muddy roads
and/or wading. •
Driving in extremely hot or cold
conditions.
• Driving in areas using road salt or other
corrosive materials.
• Towing a trailer or driving in mountainous
conditions.
Contact your Dealer/Authorised Repairer for
advice.
Emission control
Your vehicle is fitted with various items of
emission and evaporati ve control equipment,
designed to meet specific territorial
requirements. You should be aware that
unauthorised replacemen t, modification or
tampering with this equipment by an owner or
repair shop, may be unlawful and subject to
legal penalties.
In addition, engine se ttings must not be
tampered with. These have been established to
ensure that your vehicle complies with
stringent exhaust em ission regulations.
Incorrect engine settings may adversely affect
exhaust emissi ons, engine performance and
fuel consumption. The y may also cause high
temperatures, which will result in damage to
the catalytic converter and the vehicle.
Road testing dynamometers (rolling
roads)
Because your vehicle is equipped with anti-lock
brakes, it is essential that any dynamometer
testing is carried out only by a qualified person,
familiar with the dynamometer testing and
safety procedures practised by
Dealers/Authorised Repairers.
CAUTION
Ensure that you take notice of any
message centre information and
warnings relating to engi ne oil level (V8 petrol
and diesel engines only). Top-up the level
when advised to do so. See ENGINE OIL
CHECK - V8 Petrol engines (page 199).

The oil consumption of an engine is influenced
by many factors. Unde r high loads an engine
will consume more oil than usual. Diesel
engines consume slightly more oil than petrol
engines.
Above normal oil consumption should be
expected when the engine is new.
Check the oil level weekly , when the engine is
cold and with the vehicle resting on level
ground.

CAUTIONS
If the message ENGINE OIL PRESSURE
LOW is displayed, st op the engine as
soon as it is safe to do so and seek qualified
assistance. Do not start the engine until the
cause has been identified and rectified.
Your vehicle’s warranty may be
invalidated if damage is caused by the
use of improper engine oil. Low quality or
obsolete oils do not pr ovide the protection
required by modern, high performance
engines. Failure to use an oil that meets the
required specification could cause excessive
engine wear, a build up of sludge and deposits
and increased pollution. It could also lead to
engine failure.
Do not use oil additi ves of any type as
engine damage coul d occur. Use only
specified lubricants.

Checking the oil level
Note: If it is necessary to check the oil level
when the engine is hot, switch off the engine
and let stand for five minutes to allow the oil to
drain into the sump. Do not start the engine.
1. Withdraw the dipstick ( 1) and wipe the
blade clean with a lint free cloth.
2. Fully re-insert the di pstick and withdraw
again to check the oil level. Never allow the
oil level to fall below the lower mark or
notch on the dipstick.
As a general guide, if the level on the dipstick:
• Is nearer to the upper mark or notch than
the lower, add no oil.
• Is nearer to the lower mark or notch than
the upper, add half a litre (one pint) of oil.
• Is below the lower mark or notch, add one
litre (two pints) of oi l and re-check the level
after a further five minutes.
Topping up the oil
1. Unscrew the oil filler cap ( 2).
2. Add oil to maintain the level between the
MIN and MAX marks or notches on the
dipstick. Clean up any oil spilled during
topping-up.
3. Check the oil level again after 5 minutes.
It is essential to use the correct specification
oil, and to ensure it is suitable for the climatic
conditions in which the vehicle is to be
operated.
Note: The approximate quant ity of oil required
to raise the level from MIN to MAX on the
dipstick is 1.0 litre (1.76 pints).

ENGINE OIL CHECK - V8 Petrol
engines
Engine oil consumption
A certain amount of oil consumption is normal.
The rate of consumpt ion will depend on the
following:
• The quality and viscosity of the oil.
• Climatic conditions.
• The speed at which th e engine is being
operated.
• Road conditions.
Drivers should expe ct above normal
consumption when th e engine is new.
Checking the oil level
For an accurate oil level reading to be taken, the
following conditions must be met:
•The vehicle needs to be parked on level
ground. •
The oil level should be checked when the
oil is hot. It is therefore recommended that
a reading is taken after a journey.
• The vehicle needs to stand for
approximately 10 minutes after the engine
is switched off, to allow the oil to drain
back into the sump.
Note: The system will not gi ve a reading until
the oil level has stabilised.
Once the above conditions are met, check the
oil level as follows:
1. Switch on the ignition - do not start the
engine.
2. Set the transmission to Park ( P).
3. Press the TRIP butt on on the end of the
left-hand column stalk repeatedly, until the
oil can icon is displa yed at the bottom of
the message centre.
4. The oil level and topping- up advice will be
shown in the message centre. Top-up as
instructed.
CAUTIONS
It is recommended that the oil level is
checked weekly. If any significant or
sudden drop in oil level is noted you should
seek qualified assistance immediately.
Your vehicle’s warranty may be
invalidated if damage is caused by the
use of improper engine oil. Low quality or
obsolete oils do not provide the protection
required by modern, high performance
engines. Failure to use an oil that meets the
required specification could cause excessive
engine wear, a build up of sludge and deposits
and increased pollution. It could also lead to
