USING BOOSTER CABLES
Note: Before connecti ng booster cables,
ensure that the battery connections on the
disabled vehicle are correct and that all
electrical equipment has been switched off.
1. Connect one end of the positive booster
cable to the positive terminal on the donor
vehicle's battery.
2. Connect the other end of the positive
booster cable to the positive terminal on
the disabled vehicle's battery. 3.
Connect one end of th e negative booster
cable to the earth point of the donor vehicle
that is recommended for jump starting by
the manufacturer.
4. Connect the other end of the negative
booster cable to a suitable earth point on
the disabled vehicle. The earth point
should be at least 0.5 metres (20 inches)
away from the battery and as far as
possible from any fu el or brake pipes.
• Check that all cables are clear of any
moving components and that all four
connections are secure.
5. Start the engine of the donor vehicle, and
allow it to idle for a few minutes.
6. Start the engine of the disabled vehicle.
7. Allow both vehicles to idle for two minutes.
8. Switch off the donor vehicle.
Disconnecting the cables
Note: Do not switch on any electrical
equipment until after th e cables have been
disconnected.
The engine should be running on the
previously disabled ve hicle and the engine
switched off on the donor vehicle. Disconnect
the booster cables in the exact reverse order of
that used for connection.
WARNINGS
Always wear appropriate eye
protection when working with
batteries.
During normal use, batteries emit
explosive hydrogen gas - ensure
sparks and naked lights are kept away
from the luggage compartment.
Do not attempt to start the vehicle if
the electrolyte in the battery is
suspected of being frozen.
Make sure both batt eries are of the 12
volt type and that the booster cables
have insulated clamps and are
approved for use with 12 volt batteries.
Do not disconnect the discharged
battery.
Do not connect posit ive (+) terminals
to negative (-) terminals and ensure
booster cables are kept away from
any moving parts in the engine compartment.
Do not connect a booster cable to the
negative (-) terminal of the battery.
Always connect to the recommended
earthing point.
WARNING
To avoid serious in jury use extreme
caution when removing the booster
cables as the engine will be running
on the previously disabl ed vehicle. This means
that you may be workin g close to components
which are moving at high speed, carry high
voltage, or may be hot.

Battery disposal
Used batteries must be disposed of
correctly as they contain a number of
harmful substances. Seek advice on
disposal from your Dealer/
Authorised Repairer, and/or your local
authority.
WARNING
Ensure that the correct type of battery
charger is used. Using an unsuitable
charger may damage the battery and
could cause the battery to explode.
Always charge the battery in a well
ventilated area, away from any naked
flames, sparks or other ignition
sources. During charging, the battery can
produce a highly explosiv e and flammable gas.
CAUTIONS
Battery disconnecti on, removal and
replacement, should only be carried out
by qualified personne l. Consult your
Dealer/Authorised Repairer.
If the battery has been removed from
the vehicle to be charged, the Battery
Monitoring System will automatically
recalibrate. During this time, Low Battery
warning messages may appear.
Always follow the instructions supplied
with the battery charger. Failure to do so
may result in damage to the battery.
WARNING
Use caution when lifting the battery
our of, or into, the vehicle. It is heavy
and may cause injury when lifting or if
dropped.
Do not tilt the battery more than 45°,
as it may cause damage and may
cause the electrolyte to leak out.
Battery electrolyte is highly corrosive and
toxic.
CAUTIONS
Battery disconnect ion, removal and
replacement, should only be carried out
by qualified personnel. Consult your Dealer/
Authorised Repairer.
If the vehicle battery is replaced by a
new battery, the vehicle electrical
system must be reset to the new battery by
qualified personnel. Fa ilure to reset the
electrical system, may result in Low Battery
warning messages. Consult your Dealer/
Authorised Repairer.
Only a replacement battery of the same
type and specification as the original
should be fitted. Other batteries may vary in
size or have different terminal positions, which
could cause a fire hazard when connected to
the vehicle's electrical system.
Do not rest the battery on any part of the
vehicle, as it may cause damage due to
its weight.
Do not run the engine with the battery
disconnected. Doing so may damage
the charging system.

WARNINGS
Defective tyres are dangerous. Do not
drive the vehicle if a tyre is damaged,
excessively worn, or incorrectly
inflated. Doing so may lead to premature tyre
failure.
Avoid contaminating the tyres with
vehicle fluids as they may cause
damage to the tyre.
Avoid spinning the wh eels. The forces
released can damage the structure of
the tyre and cause it to fail. Doing so
may lead to premature tyre failure.
If wheel spin is unavoidable due to a
loss of traction (i n deep snow, for
example), do not exceed the 50 km/h
(30 mph) point on the speedometer. Doing so
may lead to premature tyre failure.
Do not exceed the maximum pressure
stated on the sidewall of the tyre.
Over-inflation could cause the tyre to
fail suddenly.
WARNINGS
Never drive your vehicle if the tyre
pressures are incorrect.
Under-inflation causes excessive
flexing and uneven tyre we ar. This can lead to
sudden tyre failure. Ov er-inflation causes a
harsh ride, uneven tyre wear and poor
handling.
Pressure checks should only be
carried out when the tyres are cold,
and the vehicle has been stationary
for more than three hours. A hot tyre at or
below recommended cold inflation pressure is
dangerously under-inflated.

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

The following procedure should be used to
check and adjust the tyres pressures.
1.Remove the valve cap.
2. Firmly attach a tyre pressure gauge/inflator
to the valve.
3. Read the tyre pressure from the gauge,
and add air if required.
4. If air is added to the tyre, remove the gauge
and re-attach it be fore reading the
pressure. Failure to do so may result in an
inaccurate reading.
5. If the tyre pressure is too high, remove the
gauge and allow air out of the tyre by
pressing the centre of the valve. Refit the
gauge to the valve and check the pressure.
6. Repeat the process a dding or removing air
as required until the correct tyre pressure
is reached.
7. Refit the valve cap.
Note: It is an offence in certain countries to
drive a vehicle with incorrect tyre pressures.
Note: It is the driver's responsibility to ensure
that the tyre pressures are correct.
Tyre valves
Keep the valve caps screwed down firmly to
prevent water or dirt entering the valve. Check
the valves for leaks when checking the tyre
pressures.
Pressure compensation for ambient
temperature changes
If the intended journey will take the vehicle into
an area where the ambien t local temperature is
known to be lower than the journey start point,
tyre pressure under-i nflation could occur. A colder ambient local temperature will reduce
pressure within the tyre. An effect is to
decrease sidewall height
and to increase tyre
shoulder wear with the potential for tyre failure.
Vehicle dynamics could also be adversely
affected.
In order to minimise this effect, tyre pressures
can be adjusted to compensate before the start
of the journey. Alternatively, tyre pressures can
be adjusted when the area of lower ambient
temperature is reached.
In this situation, the vehicle must be left in the
ambient local temperature for a least one hour
before tyre pressu re is adjusted.
To compensate for colder ambient
temperatures, tyre pressures should be
increased by 0.14 bar (2lbf/in², 14 kPa) for
each 10°C (20°F) decrease.
Note: Ensure that correct tyre pressures are
maintained when moving to areas of differing
ambient temperature.
The Tyre Pressure M onitoring system (TPM
system) may issue a warning if the
under-inflation becomes significant. When
driving through variable climatic conditions the
TPM system warnings may be intermittent.

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).

Replacement tyres
Ideally, tyres should be replaced in sets of four.
If this is not possible, replace the tyres in pairs
(front and rear). When tyres are replaced, the
wheels should always be re-balanced and
alignment checked.
The correct tyre specification for your vehicle
can be found on the tyre information label.
Directional tyres
Directional tyres are designed to operate
correctly when rotating forwards (when the
vehicle is travelling forwards).
Typical direction indicators
WARNINGS
Do not fit cross-ply tyres.
Do not fit tubed tyres.
Do not swap tyres around the vehicle.
Tyres bed in to the specific
characteristics of each wheel
position. Swapping them around may affect
the vehicle's handling and traction.
Always fit replacement tyres of the
same type, and wher ever possible of
the same make and tread pattern.
Replacement wheels should be
genuine Jaguar pa rts. This will
maintain the designed driving
characteristics.
If the use of tyres not recommended
by Jaguar is unavoidable, ensure that
you read, and fully comply with, the
tyre manufacturers inst ructions. Failure to do
so, may lead to tyre failure due to incorrect
fitment or use.
E95182

Wheels and tyres

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.
