2004 JAGUAR XJ Filler cap

7 - 8 Maintenance
Check Power Steering Fluid
Level
Caution: It is imperative that the
power steering system does not
become contaminated in any way.
Always dispense fluid from a fresh
sealed container and clean the area
around the reservoir neck both
before and after topping up.
Never return drained fluid to the
system.Refer to page 7 - 5 for power steering fluid
reservoir location.
Check the fluid level when the engine is
‘COLD’ and the vehicle is on a flat, level
surface.
The fluid is visible through the
translucent casing of the reservoir.
Check that the fluid level is between the
MIN and MAX marks on the side of the
reservoir.
If necessary, top up with power steering
fluid as specified by your Jaguar Retailer.
Wipe clean and remove the filler cap
from the reservoir;
take great care to
prevent any foreign matter from entering.
DO NOT OVERFILL.
Refit the filler cap.
Should the level be ve ry low, report the
loss of fluid to the nearest Jaguar Retailer.
!WARNING:
1. Do not allow power steering fluid to make contact with skin or eyes.
If this happens, rinse the affected
area immediately with plenty of
water.
2. Power steering fluid is toxic and flammable. Be sure to observe all
warnings indicated on the power
steering fluid container.

Maintenance 7 - 9
Check Brake Fluid Reservoir
Refer to page 7 - 5 for brake fluid reservoir
location. The brake fluid reservoir is
concealed by a lift-out cover.
To remove the lift-out cover, pull the two
clips on the rear edge of the cover
towards the front of the car, and lift the
cover out.
Caution:
1. While handling brake fluid, take extreme care; brake fluid must not
contact the vehicle paintwork.
2. Always use fresh, clean fluid from a new container. Never introduce
used brake fluid into the system. The fluid is visible through the
translucent casing of the reservoir and
must be maintained at the ‘MAX’ mark.
!WARNING:
The fluid level will drop as the brake
pads wear. If the le vel is very low
report the loss of fluid to the nearest
Jaguar Retailer. Do not drive the
vehicle until the cause is rectified.
If necessary, top up as follows:
Before removing the cap, clean the
reservoir and cap thoroughly with a non-
fluffy cloth to ensure that no foreign
matter enters the reservoir.
Unscrew the filler cap and top up to the
‘MAX’ level using brake fluid to
specification Jaguar Super DOT 4
(ESA-M6C25-A) .
Refit the filler cap securely.
To avoid contamination should any brake
fluid be spilt, replace the cap on the
reservoir before cleaning the spilt fluid
from the vehicle. Hydraulic fluid
The brake hydraulic fluid in the master
cylinder and brake operating system uses
non-mineral polyglycol based brake fluid
with a minimum standard of JAGUAR
SUPER DOT 4. ONLY FLUID OF THIS
TYPE AND STANDARD MAY BE USED.
!WARNING:
1. Contamination of the brake system fluid by as little as
1 per cent will cause rapid
deterioration of t he system seals.
Ensure that the brake fluid
reservoir cap is securely fitted.
2. Do not allow brake fluid to make contact with skin or eyes. If this
happens, rinse the affected area
immediately with plenty of water.
3. Brake fluid is toxic and flammable. Be sure to observe all warnings
indicated on the brake fluid
container.

Maintenance 7 - 11
Check Coolant Level
Refer to page 7 - 5 for coolant header tank
location.
The coolant level MAX and MIN
indicators are located inside the reservoir
and are only visible when looking into the
filler neck with the cap removed. Check
the level only when the engine is cold.
The coolant level shou ld be between the
MAX and MIN indicators. If persistent
coolant loss is noticed, have a Jaguar
Retailer investigate the cause
immediately.
!WARNING:
Do not remove the coolant header
tank filler/pressure cap while the
engine is hot. If the cap must be
removed, protect the hands against
escaping steam and slowly turn the
cap anti-clockwise until the steam
starts to escape. Leave the cap in this
position until the pressure is
released, and then remove the cap.
Topping up
!WARNING:
Do not allow anti-freeze to make
contact with skin or eyes. If this
happens, rinse the affected area
immediately with plenty of water.
Caution: Anti-freeze will damage
paintwork. Avoid spillage.
Top up with a mixture of 50% water and
50% anti-freeze until the coolant is
between the MAX and MIN indicators
inside the header tank. Use anti-freeze to
specification WSS M97B44, coloured
orange, Extended Life Coolant.
Refit the filler cap and hand-tighten
securely until the ratchet operates. Engine anti-freeze
When used at the correct concentration,
anti-freeze not only protects the engine
from frost damage in winter, it also
provides all year round protection against
internal corrosion.
The cooling system should always be
topped up or refilled with the specified
anti-freeze at the correct concentration.
This 50/50% mixture gives frost
protection for temperatures down to
–40°F (–40°C).
Do not mix any other anti-freeze with
that specified; inferior quality anti-freeze
may be ineffective in maintaining
adequate frost and corrosion protection
to the cooling system.
The coolant solution
may remain in the
cooling system for five years or
156,000 miles (250,000 km) after which
the system should be drained, flushed
and refilled.
Engine block heater
For further information consult your
Jaguar Retailer.
Caution: The fitting of an engine
block heater does not eliminate the
need for anti-freeze under freezing
conditions.

7-18 Maintenance
Tyres
Tyres of the correct type, manufacturer
and dimensions, with correct cold
inflation pressures are an integral part of
every vehicle’s design. Regular
maintenance of tyres contributes not only
to safety, but to the de signed function of
the vehicle. Road-holding, 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 have widely varying
characteristics. It is therefore
recommended that Jaguar approved tyres
are fitted to all wheels.
A tyre recommendation placard is placed
on the inside of the fuel filler flap, giving
information specific to the vehicle’s
wheel and tyre equipment.
Always ensure that the wheel nuts are
fully seated before finally tightening the
nuts in alternate sequence.
W, Y and Z-rated performance tyres are
optimised for driving dynamics and have
limited winter traction ability. Compared
with H-rated all-season tyres, they may
incur increased tread wear, reduced ride
comfort, and increased road noise.
Tyre Renewal
When renewing tyres, it is preferable to
fit a complete vehicle set. If either front
or rear tyres only need to be renewed,
new tyres must be fitted, as axle sets,
to replace worn ones. After new tyres
have been fitted the wheels need to be
dynamically balanced. The radial ply
tyres specified are designed to meet the
high-speed performance capability of this
vehicle (see page 8 - 7) . Do not fit tyres
with a different tread pattern, size or
speed rating.
Tyre Pressures
The recommended tyre pressures are
written on a label, inside the fuel filler
flap. These tyre pressures provide
optimum ride and handling
characteristics for all normal operating
conditions. The pressures should be
checked, and correctly set each week
with the tyres cold. Tyre temperatures
and pressures increase when running.
Deflating a warm tyre to the
recommended pressure will result in
under inflation whic h may be dangerous.
A slight natural pressure loss occurs with
time. If this exceeds 2 lbf/in² (0.14 bar,
14 kPa, 0.14 kg/cm²) per week, the cause
should be investigated and rectified.
Note: It is an offence in certain countries
to drive a vehicle with tyres that are not
inflated in accordance with the vehicle’s
proper use.

Tyre Pressures
The tyre pressures recommended by Jaguar Cars to maintain optimum ride and handling characteristics for all normal operating
conditions are shown on a label affixed to the inside of the fuel filler flap.
For your convenience you may wish to record the tyre pressures in the boxes provided below. If you are unsure of the correct
pressures please contact your Jaguar Retailer.
