Petrol engines (page 197).
• Engine coolant check. See ENGINE
COOLANT CHECK (page 204).
• Brake fluid level. See BRAKE FLUID
CHECK (page 206).
• Power steering fluid level. See POWER
STEERING FLUID CHECK (page 208).
• Screen washer fluid level. See WASHER
FLUID CHECK (page 209).
• Tyre pressures and condition. See TYRE
CARE (page 217).
• Operate air conditioning. See AUTOMATIC
CLIMATE CONTROL (page 116).
Note: The engine oil level on V6 petrol engines,
should be checked more frequently if the
vehicle is driven for prolonged periods at high
speeds. The engine oil level on diesel and V8
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).

BRAKE FLUID CHECK
If the quantity of fluid in the brake
reservoir drops below the
recommended level, a red warning
indicator in the instrume nt pack will illuminate
and the message BRAKE FLUID LOW will be
displayed in the message centre.
Note: If the warning indicator illuminates or the
message is displayed, while the vehicle is being
driven, stop the vehicle as soon as safety
permits by gently applying the brakes. Check
and top-up the fluid level if necessary.
Checking the fluid level
With the vehicle on level ground, check the
fluid level at least every week (more frequently
in high mileage or arduous operating
conditions).
The brake fluid reservoi r is located beneath a
cover on the raised platform to the rear of the
main underbonnet area. See ENGINE
COMPARTMENT OVERVIEW (page 196).
1. Release the catch.
2. Lift the cover forwards, then pull
rearwards, to release the hinges.
3. Clean the filler cap with a clean, dry cloth
before removing, to prevent dirt or
moisture from entering the reservoir.
WARNING
Seek qualified assistance immediately
if brake pedal travel is unusually long,
unusually short or if there is any
significant loss of br ake fluid. Driving under
such conditions could result in extended
stopping distances or co mplete brake failure.
WARNINGS
Brake fluid is highly toxic - keep
containers sealed a nd out of reach of
children. If accidental consumption is
suspected, seek medical attention
immediately.
If the fluid comes into contact with
the skin or eyes, rinse immediately
with plenty of water.
Brake fluid is highl y inflammable. Do
not allow brake fluid to come into
contact with naked flames or other
sources of ignition (e.g. a hot engine) - a fire
may result.
Do not drive the vehicle with the fluid
level below the MIN mark.

Wheels and tyres
218

All of the vehicle's tyres (including the spare)
should be checked regularly for damage, wear
and distortion. If you are in any doubt about the
condition of a tyre, have it checked immediately
by a tyre repair centre or your
Dealer/Authorised repairer.
Checking the tyre pressures
The recommended tyre pressures are listed on
a placard label fixed to the end of the left-hand
side door. These pressures provide optimum
ride and handling charac teristics for all normal
operating conditions.
If winter tyres are fitted, please refer to the
winter tyre pressure information. SeeUSING
WINTER TYRES (page 223).
In the interest of safe ty, reliability and fuel
efficiency, check the tyres, including the spare,
for condition and pressu re on a weekly basis
and before long journeys.
Do not check tyre pressures immediately after
the vehicle has travelled in excess of 1.6 km
(1.0 mile). Tyre temperatures and pressures
increase when running. Deflating a warm tyre
to the recommended pressure will result in
under-inflation.
If tyre pressures are checked while the vehicle
is inside a protected covered area, e.g. a
garage, and subsequent ly driven in lower
outdoor temperatures, tyre under-inflation
could occur.
A slight pressure loss occurs naturally with
time. If this exceeds 0.14 bar (2 lbf/in², 14 kPa,)
per week, have the cause investigated and
rectified by qualified assistance.
Tyre pressures (including the spare) should be
checked at least once a week with normal
on-road use, but should be checked daily if the
vehicle is used off-road. Always check the tyre
pressures before setti ng off on a long journey.
If it is necessary to check tyre pressures when
the tyres are warm, you should expect the
pressures to have increased by up to
0.3-0.4 bar (4-6 lbf/in², 30-40 kpa). Do not
reduce the tyre pressures to the cold inflation
pressure under these circumstances. Allow the
tyres to cool fully before adjusting the
pressures.
If the vehicle has been parked in
strong sunlight, or used in high
ambient temperatures do not reduce
the tyre pressures. move the vehicle into the
shade and allow the tyres to cool before
re-checking the pressures.
WARNING
Tyre pressures should be checked
regularly using an accurate pressure
gauge, when the tyres are cold.
Failure to properly maintain your tyre
pressures could increase the risk of tyre failure
resulting in loss of vehicle control and
personal injury.

Wheels and tyres

Wear indicators
When the tread has worn down to
approximately 2 mm, wear indicators start to
appear at the surface of the tread pattern. This
produces a continuous band of rubber across
the tread as a visual indicator.
To maintain performance and grip the tyre
must be replaced as soon as the wear indicator
becomes visible. Sooner, if legislation requires
replacement at a greater tread depth.
Note: Tread depth should be checked
regularly, in some case more frequently than
the service intervals. For advice on checking
tyres contact your Dealer/Authorised repairer
or a tyre dealer.
Age degradation
Tyres degrade over time due to the effects of
ultraviolet light, extreme temperatures, high
loads, and environmen tal conditions. It is
recommended that tyres are replaced at least
every six years, but they may require
replacement more frequently.
Jaguar recommends that even if unused, the
spare tyre be replaced at the same time as the
four road tyres.
Punctured tyres
Tyre checks
Not all punctures result in the tyre deflating
immediately. Therefore, it is important to check
the tyres for damage and foreign objects,
regularly.
When driving, if a sudden vibration, or change
to the vehicle's hand ling is noticed, reduce
speed immediately. Do not brake hard, or make
any sudden manoeuvres or direction changes.
Drive slowly to an area off the main highway
and stop the vehicle.
Note: Driving the vehicle to a safe area may
cause damage to th e punctured tyre, but
occupant safety is far more important.
Inspect the tyres for signs of punctures,
damage or under inflati on. If any damage or
deformity is detected, the tyre should be
replaced. If a spare tyre is not available, then
the vehicle should be reco vered to a tyre repair
centre, or Dealer/Approved repairer.
WARNING
Wear indicators show the minimum
tread depth recommended by the
manufacturers. Tyres which have
worn to this point will have reduced grip and
poor water displacement characteristics.
CAUTION
If tread wear is uneve n across a tyre, or
the tyre wears excessively, the vehicle
should be checked by your Dealer/Authorised
Repairer as soon as possible.
E91698
WARNING
Do not drive the vehicle with a
punctured tyre. Even if the punctured
tyre has not deflated, it is unsafe to
use, as the tyre may deflate suddenly at any
time. See TYRE REPAIR KIT (page 229).

RUN FLAT TYRES
Run-flat tyres can be identified by the lettering
RSC on the sidewall. The tyre construction
utilises a specially reinforced sidewall, which
allows the vehicle to be driven at restricted
speeds, even when the tyre is depressurised.
Run-flat tyres can only be fitted to special rims,
constructed for ru n-flat tyre use.
A tyre pressure monitoring system is
mandatory when the vehicle is fitted with
run-flat tyres. See TYRE PRESSURE
MONITORING SYSTEM (page 234).
If the tyre has deflated, the vehicle should be
driven with caution, as handling characteristics
will be different compared to a fully inflated
tyre.
If the vehicle is fully la den with passengers and
luggage, the maximum di stance that can be
completed on a fully deflated tyre, is
approximately 80 kilo metres (50 miles).
Stop immediately if the tyre construction
begins to break down or if the tyre dislodges
from the wheel rim. Typi cally, this will be
accompanied by excessive vibration.
A tyre driven in a defl ated condition must be
replaced as s oon as possible. Vehicles fitted with run-flat tyres are not fitted
with a spare wheel or jacking equipment.
Therefore, run-flat tyre
s should be replaced
with the same type of tyre.

Locking wheel nuts
Vehicles may be equipped with a locking wheel
nut on each wheel. These are similar to
standard wheel nuts, and can only be removed
using the special adaptor provided with the
jacking equipment.
1. Insert the adaptor firmly onto the locking
wheel nut.
2. Using the wheel brace, unscrew the wheel
nut and adaptor.
3. Return the locking wheel nut adaptor to the
correct storage position.
