CHANGING THE VEHICLE BATTERY
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.

GENERAL INFORMATION
Tyre markings
1.P indicates that the tyre is for passenger
vehicle use.
2. The width of the tyre fr om sidewall edge to
sidewall edge in millimetres.
3. The aspect ratio, also known as the profile,
gives the sidewall height as a percentage
of the tread width. So, if the tread width is
205 mm, and the aspect ratio is 50, the
sidewall height will be 102 mm.
4. R indicates that the ty re is of Radial ply
construction.
5. The diameter of the wheel rim given in
inches.
6. The load index for the tyre. This index is
not always shown.
7. The speed rating denotes the maximum
speed at which the tyre should be used for
extended periods. † 8.
Tyre manufacturing standard information,
which can be used for tyre recalls and
other checking processe s. Most of this
information relates to the manufacturer,
place of manufacture etc. The last four
numbers are the date of manufacture. For
example, if the number was 3106, the tyre
was made in the 31st week of 2006.
9. M+S or M/S indicates that the tyre has
been designed with some capability for
mud and snow.
10. The number of plies in both the tread area,
and the sidewall area, indicates how many
layers of rubber coat ed material make up
the structure of the tyre. Information is
also provided on the type of materials
used.

11.Wear rate indicator. A tyre rated at 400 for
example, will last twice as long as a tyre
rated at 200.
12. The traction rating grades a tyres
performance when stopping on a wet road
surface. The higher the grade the better the
braking performance. The grades from
highest to lowest are, AA, A, B, and C.
13. The maximum load which can be carried
by the tyre.
14. Heat resistance grading. The tyre's
resistance to heat is grade A, B, or C, with
A indicating the greatest resistance to heat.
This grading is provided for a correctly
inflated tyre, which is being used within its
speed and loading limits.
15. The maximum inflation pressure for the
tyre. This pressure should not be used for
normal driving.

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.

Tyre pressure compensation chart - high
ambient temperatures
Tyre pressures during long term vehicle
storage
To minimise the possibility and effects of flat
spots during storage, the tyres may be inflated
to the maximum pressure indicated on the tyre
wall.
Note: Before using the st ored vehicle on the
road again, ensure that correct tyre pressures
are restored.
Flat spots
If the vehicle is stati onary for a long period,
when the ambient temperature is high, the
tyres may form flat spots. When the vehicle is
driven, these flat spots will cause a vibration
which will steadily disappear as the tyres warm
up and regain their original shape. In order to minimise flat spotting, the tyre
pressures can be increa
sed. Tyre pressures
should be increased by 0.14 bar/14 kPa (2
lbf/in²) for each 10°C (20°F) temperature
increase above 20°C (68°F)
Long term storage
Flat spotting can be minimised during long
term storage, by increasing the tyre pressures
to the maximum indicated on the tyre sidewall.
Note: The tyre pressures s hould be reduced to
the correct pressure before the vehicle is
driven.
Tyre wear
Good driving practise will improve the mileage
you obtain from your tyres, and avoid
unnecessary damage.
• Always ensure that the tyre pressures are
correctly adjusted.
• Always observe the posted speed limits,
and advisory speeds for bends.
• Avoid pulling away quickly, or hard
acceleration.
• Avoid making fast turns or braking
sharply.
• Wherever possible, avoid potholes, or
obstacles on the road.
• Do not drive up kerbs, or rub the tyres
against them when parking.

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.

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.

CHANGING A ROAD WHEEL
If a wheel change is required, pull off the road
completely. Park on ground which is as level
and solid as possible. Ensure that the vehicle is
clear of any objects that will obstruct the safe
removal of the wheel. Switch on hazard
warning lamps and, where legally required,
display the warning triangle.
Regular maintenance of tyres contributes not
only to safety, but to the designed function of
the vehicle. Road-holdi ng, steering and braking
are especially vulnerable to incorrectly
pressurised, badly fitted or worn tyres.
Tyres of the correct size and type, but of
different make can have widely varying
characteristics. It is therefore recommended
that Jaguar approved tyres are fitted to all
wheels.
Temporary use spare wheel
Observe the following wa rnings before using
the wheel:
WARNINGS
Always ensure replacement tyres
have the correct rating and
specifications (e.g. load index, size,
speed rating) for your vehicle.
When using tyres other than those
recommended by Jaguar, do not
exceed the speed capacity
recommended by the manufacturer.
Wheels are extremely heavy. Take
care when lifting and particularly
when removing and replacing a wheel
in its storage position in the luggage
compartment.
CAUTION
Ultra high performance tyres. This
vehicle is equipped with an Ultra High
Performance (UHP) tyre and wheel
combination designed to give maximum dry
road performance with consideration for
aquaplaning resistan ce. UHP tyres have
performance enhancing soft rubber tread
compound. If driven aggressively they may
suffer rapid tread wear and a shorter life than
can be expected from other tyre types. This
wheel and tyre comb ination is more
susceptible to damage from road hazards.
Do not use this combination for driving on
snow or ice. High perf ormance tyres must be
replaced with winter tyres when weather
conditions dictate.
WARNINGS
Note the temporary use spare wheel
warning label. Adhere to instructions
on the label. Failure to comply can be
dangerous.
When a temporary use spare wheel is
fitted, drive with caution and replace
with the specified wheel and tyre as
soon as possible.
Do not fit more than one temporary
use spare wheel and tyre assembly at
one time.
The temporary use spare wheel must
be inflated to 4.2 bar (60 lbf/in²,
420 kPa) and cannot be repaired.
Temporary use spare wheel,
maximum speed is 80 km/h
(50 mph).
