2004 JAGUAR XJ Locking

On the Road 4 - 47
Anti-lock Braking
System (ABS)
This system helps to prevent the road
wheels from locking and skidding during
emergency braking, assisting the driver to
maintain full steering and directional
stability.
The factor controlling ultimate stopping
distance and cornering ability is tyre/road
adhesion.
!WARNING:
1. The fact that a vehicle is fitted with ABS must never allow the
driver to be tempted into taking
risks which could affect his/her
safety or that of other road users.
2. The addition of ABS cannot overcome the consequences of
trying to stop in too short a
distance, cornering at too high a
speed, or the risk of aquaplaning. 3. The driver should always take
road conditions into account.
A slippery road surface always
requires more braking distance
for a given speed, even with ABS.
A possible increase in stopping
distance compared to locked
wheels may occur during ABS
operation on slushy snow, gravel,
sand, or some heavily corrugated
or ridged warning sections of road
surfaces.
ABS optimises tyre/road adhesion under
maximum braking conditions though it
cannot provide increased cornering
ability. There is no need for special
braking techniques, such as ‘pumping’
the brakes, to achieve optimum braking
distances and control on poor or slippery
road surfaces. Tyres must be in good
condition to achieve maximum adhesion. During normal brakin
g the ABS will not
be activated. Howe ver, if the braking
force applied begins to exceed tyre/road
adhesion the ABS will automatically
activate, preventing the road wheels from
locking.
In these circumstances a pulsating effect
will be felt from the brake pedal
indicating that the sy stem is functioning.
The pulsating effect is due to small
fluctuations in pressure supplied to the
brakes by the system to maintain full
tyre/road adhesion.
Under severe braking on some road
surfaces tyre noise may be apparent even
though the wheels will at no time become
locked.

4-60 On the Road
Use of Headlamps In Daylight
When visibility is poor the headlamps
with dipped beam setting should be
switched on so that the vehicle may be
seen more easily by other road users.
The instrument illumination dimmer
control adjusts the brightness of the panel
lighting.
Engine Oil Consumption
A certain amount of oil consumption is
normal. The rate of consumption will
depend on the following:
• The quality and viscosity of the oil.
• The amount of oxidation and dilution of the oil.
• Climatic conditions.
• The speed at which the engine is being operated.
• Road conditions.
Drivers should expect above normal
consumption when the engine is new,
and after running-in if high speeds are
sustained.
Winter Driving
Freeing a frozen door lock
Caution: Do not ap ply a proprietary
lock de-icer through the keyhole.
Should the lock beco me frozen, warm the
end of the key before use.
Windscreen wiper blades
Before driving away, clear any ice from
the windscreen and check that the wiper
blades are free. Switching on the heated
screen will accelerate this process.
The heated wiper park, if fitted, will come
on automatically.
Frost precautions
The correct concentration of coolant
must be maintained at all times when
‘topping up’ or ‘refilling’ the cooling
system.
Parking the Vehicle
When leaving the vehicle, remember the
following:
• Whenever the vehicle is being parked, apply the parkbrake and move the
gear selector to Park ‘P’.
• Do not leave children or pets in the vehicle unattended.
• Do not leave luggage or valuables on view. Always take your valuables with
you or lock them in the luggage
compartment.
• Remove the ignition key and spare keys, even when the vehicle is in your
garage.
• When the vehicle is unoccupied, close
all windows and lock all doors
securely.
• Park the vehicle where it can be seen. At night, park in a well-lit area.
• Ensure that the keys and the key transmitters are removed from the
vehicle before locking the doors,
and that all doors, the luggage
compartment and the hood are
closed.

Roadside Emergency 6 - 7
Locking Wheel Nuts
Where Jaguar locking wheel nuts are
fitted (one on each wheel), they can only
be removed using the correct key socket.
The locking wheel nut comprises two
grooved parts, front and rear, which must
be turned together to allow the nut to be
fitted or removed.
To remove the nut, the front and rear
grooves must be aligned. Locate the key
socket in the grooves and push it fully
over both parts of the nut. Fit the wheel
nut wrench over the key socket and
loosen the locking wheel nut (turn anti-
clockwise). Attempting to remove the nut without the
correct key socket
(such as attempted
theft) or with the socket not located over
the rear part of the nut, will cause the
front part only ( A) to turn.
If this has happened, rotate the front part
with the key socket until the grooves are
re-aligned and then push the socket fully
over the nut.
Should a new key socket be required,
contact your Jaguar Retailer. Proof of
vehicle ownership will be required.

6 - 8 Roadside Emergency
Spare Wheel and Jack Removal
!WARNING:
Wheels are extremely heavy.
Take care when lifting and
particularly when removing and
replacing a wheel in its storage
position in the luggage compartment.
The spare wheel and jacking equipment
are stored under the trunk floor panel.
Seepage6-4.
To remove the spare wheel, fully unscrew
the locking ring ( A). Unscrew the wing
nut below the locking ring. This allows
wheel retainer ( B) to be lifted and
removed. The wheel can now be lifted
out.

6 - 10 Roadside Emergency
!WARNING:
1. Do not attempt to lift the vehicle unless the jack head is fully
engaged in the jacking point.
2. Ensure that the parkbrake is applied.
Place the jack squarely beneath the
appropriate jacking point. Ensure that the
jack head is fully engaged. Carefully raise
the vehicle by turning the handle.
Stop jacking the vehicle when the tyre
just clears the ground. Minimum tyre lift
gives maximum vehicle stability.
Remove the wheel nuts and the wheel.
Centre badge
When changing the alloy road wheels,
transfer the centre badge to the
replacement wheel. Using the plastic
tipped end of the wheel nut wrench
handle from the inside of the wheel, push
the centre badge from its housing.
Push the centre badge into the
replacement wheel. Fitting the spare wheel
Fit the spare wheel and loosely secure
with 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 ti ghten the wheel nuts
alternately, DO NOT OVER TIGHTEN.
At the earliest opportunity have the
wheel nuts tightened with a torque
wrench to 92 lb.ft (125 Nm).
This torque must not be exceeded. Stowing the equipment
Stow the replaced road wheel in the
trunk.
Check that the locking ring is unscrewed
fully so that it is as close as possible to the
handle of the wheel retainer. This is to
ensure that the wheel retainer can be
fitted correctly.
Locate the wheel retainer into its mating
thread in the trunk floor and tighten it
fully, then tighten the locking ring
clockwise to secure the wheel.
Seepage6-8.
Stow the jacking equipment.
Close the trunk floor panel.
!WARNING:
When a temporary spare wheel is
fitted, drive with caution and replace
with the specified wheel and tyre as
soon as possible.
