GENERAL INFORMATION
Regular systematic maintenance is the key to
ensuring the continued reliability and efficiency
of your vehicle.
Maintenance is the owner's responsibility and
you must ensure that owner maintenance
operations, oil services, inspections and brake
fluid and coolant changes are carried out when
required and according to the manufacturer's
recommendations.
The routine maintenance requirements for your
vehicle are shown in th e Service Portfolio book.
Most of this necessar y workshop maintenance
requires specialised knowledge and
equipment, and should preferably be entrusted
to a Dealer/Authorised Repairer.
Service Portfolio
The Service Portfolio book includes a Service
Record section, which enables a record to be
kept of all the servicing and inspections that are
carried out on the vehicle. This section of the
book also has an area for brake fluid changes
to be recorded.
Ensure your service provider signs and stamps
the book after each se rvice and inspection.
Owner maintenance
In addition to the routine services and
inspections, a number of simple checks must
be carried out more frequently. These checks
can be carried out by th e owner and advice is
given on the pages that follow.
Daily checks
• Operation of lamps, horn, direction
indicators, wipers, washers and warning
indicators.
• Operation of seat belts and brakes.
• Look for fluid deposits underneath the
vehicle that might indicate a leak.
Condensation drips from the air
conditioning is normal.
CAUTION
Severe damage to the electrical system
and electronic components can occur, if
any attempt is made to diagnose faults in the
electrical system using conventional
diagnostic equipment (e .g. the use of test
lamps or low impedanc e voltmeters). The
fitting of any electric al accessory should only
be entrusted to a Deal er/Authorised Repairer.CAUTION
Any significant or sudden drop in fluid
levels, or uneven tyre wear, should be
reported to a qualifie d technician without
delay.

Maintenance

Weekly checks
•Engine oil level (non- electronic dipstick
vehicles). See ENGINE OIL CHECK - V6
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).

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

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).

USING WINTER TYRES
Winter tyres are more suitable during extremes
of low temperatures, snow and ice and will
considerably improve the vehicle’s handling
during these conditions.
Do not exceed 240 km/h (150 mph) when
using Jaguar approved winter tyres.
Winter tyres must be fitted to all four wheels.
Approved winter tyre sizes
Front :
• Dunlop Wintersport M3 - 235/55R17 99H,

USING SNOW CHAINS
Snow chains, of the recommended type, can
only be fitted to rear wheels. They should not
be used on temporary use spare wheels.
You should contact your Dealer/Authorised
Repairer for details and availability of approved
snow chains.
The maximum speed when using snow chains
is 50 km/h (30 mph).
Remove the snow chains immediately the
roads are clear of snow.
Ensure the fitting instructions supplied with the
snow chains are kept in a safe place, for
example, with this literature pack.
Note: When using snow chains, select
JaguarDrive Control Winter mode with DSC
switched on.
CAUTION
Tyres with an all season icon or M+S
have a level of winter performance and
need not be replaced.
Up to 240 km/h (150 mph)
Front 2.0 bar (30 lbf/in², 207 kPa)
Rear 2.3 bar (33 lbf/in², 230 kPa)
CAUTION
It is essential that only snow chains of
the recommended type are fitted, other
snow chains may cause damage to the vehicle.

Wheels and tyres

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).

Using the Jaguar tyre repair kit
Note: All vehicle drivers and occupants should
be made aware that a temporary repair has
been made to a tyre fitted to the vehicle. They
should also be made aware of the special
driving conditions im posed when using a
repaired tyre.
Repair procedure
1. Open the tyre repair kit and peel off the
maximum speed label. Attach the label to
the fascia in the driver's field of vision.
Take care not to obstruct any of the
instruments or warning lights.
2. Uncoil the compressor power cable and
the inflation hose.
3. Unscrew the orange cap from the sealant
bottle receiver and the sealant bottle cap.
4. Screw the sealant bottle into the receiver
(clockwise) until tight.
•Screwing the bottle onto the receiver will
pierce the bottle's se al. Do not unscrew
a full, or partly us ed bottle from the
receiver. Doing so will result in sealant
leaking from the bottle.
5. Remove the valve cap from the damaged
tyre.
6. Remove the protective cap from the
inflation hose and connect the inflation
hose to the tyre valve. Ensure that the hose
is screwed on firmly.
7. Ensure that the compressor switch is in
the off (0) position.
8. Insert the power cable connector into the
auxiliary power socket. See AUXILIARY
POWER SOCKETS (page 125).
WARNINGS
Avoid skin contact with the sealant
which contains natu ral rubber latex.
If the tyre inflati on pressure does not
reach 1.8 bar (26 lbf/in², 180 kPa)
within seven minutes, the tyre may
have suffered excessive damage. A temporary
repair will not be poss ible, and the vehicle
should not be driven until the tyre has been
replaced.
CAUTIONS
Before attempting a ty re repair, ensure
that the vehicle is parked safely, as far
away from passing traffic as possible.
Ensure that the parki ng brake is applied
and P (Park) is selected.
Do not attempt to remove foreign
objects such as nails, screws, etc. from
the tyre.
Always run the engine when using the
compressor, unless the vehicle is in an
enclosed or poorly ventil ated space, as this
may cause asphyxiation.
To prevent overheating, do not operate
the compressor continuously for longer
than ten minutes.
WARNING
Check the tyre sidewall prior to
inflation. If there are any cracks,
bumps or similar damage, do not
attempt to inflate the tyre. Do not stand
directly beside the tyre while the compressor
is pumping. Watch the ty re sidewall. If any
cracks, bumps or simila r damage appear, turn
off the compressor and let the air out by
means of the pressure relief valve. Do not
continue to use the tyre.
