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

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).

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).

Wheel changing safety
Before raising the vehicle, or changing a wheel
ensure that you read, and comply with the
following warnings.
WARNINGS
Always find a safe place to stop, off
the highway and away from traffic.
Ensure that the vehicle is on firm level
ground.
Disconnect traile r/caravan from
vehicle.
Switch on the hazard warning lamps.
Ensure that all passengers, and
animals, are out of the vehicle and in
a safe place away from the highway.
Place a warning triangle at a suitable
distance behind th e vehicle, facing
towards oncoming traffic.
Ensure that the front wheels are in the
straight ahead position, and engage
the steering lock.
Apply the parking br ake, and engage
Park (P).
Ensure that the jack is on firm level
ground.
Never place anything between the
jack and the ground, or the jack and
the vehicle.
When one rear wheel is lifted off the
ground the selection P (Park) position
will not prevent the vehicle from
moving and possibly slipping off the jack as
the park brake only operates on the rear
wheels.
Do not start or run the engine while
the vehicle is supported only by a
jack.
The jack is designed for use when
changing a wheel only. Never work
beneath the vehicle with the jack as
the only means of s upport - use vehicle
support stands.
Always chock the wheel diagonally
opposite the wheel to be changed,
using the wheel chock supplied in the
tool kit. Chock the front of a front wheel, or the
rear of a rear wheel.
If jacking the vehicle on a slight slope
is unavoidable, place chocks on the
downhill side of the two opposite
wheels. An additional chock will be
needed.
Take care when lifting the spare
wheel, and removing the punctured
wheel. The wheels are heavy, and can
cause injuries if not handled
correctly.
Remove the spare wheel prior to
jacking the vehicle. To avoid
destabilising the vehicle when raised.
Take care when loosening the wheel
nuts. The wheel brace may slip off if
not properly attached, and the wheel
nuts may give way suddenly. Either
unexpected movement ma y cause an injury.
WARNINGS

Wheels and tyres

Tightening the wheel nuts
Using the wheel nut wrench, lightly tighten the
wheel nuts alternately using the sequence
shown in the illustration.
Lower the jack and tighten the wheel nuts
alternately. Do not over tighten by using foot
pressure or extension bars on the wheel nut
wrench.
At the earliest opportuni ty have the wheel nuts
tightened with a torque wrench to 125 Nm
(92 lb.ft).
This torque must not be exceeded.
TYRE REPAIR KIT
Your vehicle may not be equipped with a spare
tyre. If this is the case, in its place in the rear
underfloor storage compartment, you will find
a Jaguar tyre repair kit (except where run-flat
tyres are fitted). The Jaguar tyre repair kit can
be used to repair one tyre and it is essential
that you read the following guide before
attempting to repair a tyre.
The Jaguar tyre repair kit seals most punctures
caused by nails, or si milar items, with a
maximum diameter of 6 mm (1/4 inch).
Note: The sealant used in the tyre repair kit has
a shelf life and the expiry date is shown on the
tyre sealant bottle. Ensure that the container is
replaced before the expiry date.
