2004 JAGUAR XJ roadside towing

4-58 On the Road
Vehicle Suspension
This vehicle is fitted with a fully
automatic air suspension system.
It ensures that the vehicle is always at the
correct ride height with varying load
conditions, including luggage
compartment load or when towing.
The system will automatically adjust the
amount of air in the springs to level the
vehicle. Air is supplied either from an air
reservoir or a compressor.
The compressor will run periodically to
refill the reservoir.
Changes in ambient temperature will also
have an effect on vehicle height when the
vehicle is parked.
Caution:
1. Do not overload the vehicle. Vehicle load weights are shown
on page 8 - 4.
2. A slight air loss is expected over time causing the vehicle to lower,
so do not store or place anything
under the vehicle if it is to be left
for an extended period. Speed lowering
When driving at motorway speeds,
the system will lower the vehicle to
improve aerodynamics and vehicle
stability. The suspension will
automatically return the vehicle to the
normal height when the vehicle slows.
Caution: Speed lowering is
undesirable when towing.
Only Jaguar approved towing
equipment will not allow this feature.
Warning messages
If the message ‘VEHICLE TOO LOW’ is
displayed when the ignition is switched
on, start the engine and wait for the
suspension to raise. The vehicle should
not be driven until the message is
cleared.
If the message ‘VEHICLE TOO LOW’ is
displayed when driv
ing, restrict the
vehicle speed and wait for the system to
regain the correct height and the message
will then clear. If the message is displayed
frequently, it is advisable to inform your
Retailer to have the system attended to.
If the message ‘AIR SUSPENSION FAULT’
is displayed at any time, drive with
caution. Have the vehicle checked by a
Retailer at the earliest opportunity.
Note: If your vehicle needs to be
recovered by a roadside emergency
service ensure that the vehicle is securely
lashed by the wheels and NOT the body.

Trunk Underfloor Access
The space under the trunk floor houses
the spare wheel, battery, jack and rear
fuse box.
To raise the floor panel, press down the
rear of handle (A) then, holding the
handle at the front, swing the floor panel
upwards ( B). Hook the handle securely
over the top edge of the trunk
opening ( C).
Emergency Starting
This vehicle is fitted with automatic
transmission. In the event of a discharged
battery preventing a normal engine start,
the vehicle cannot be started by pushing
or towing. Either use jump leads
connected to a booster battery (e.g. on
another vehicle) or fit a fully charged
battery (see page 7 - 15).
Emergency Starting Using
Jump Leads
Both the booster and discharged battery
should be treated with great care when
using jump leads. Al ways use high quality
leads capable of carrying the starter
current of the vehicle to be started.
Before commencing, the following
precautions must be taken:
• When the battery of another vehicle is being used, ensure that the vehicles
do not touch. Alternatively, remove
the charged battery and place near to,
not on, the vehicle with the
discharged battery.
• Ensure that both vehicles have all electrical services OFF,
the parkbrakes applied and the
transmission in the ‘P’ (park) position.
• Where the jump leads are of a different colour, e.g. red and black,
use red for positive (+). This aids
identification and helps to avoid
crossing positive (+) to negative (–).
Take extra care to avoid crossing the
polarity when using cables of the
same colour.

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.

6 - 12 Roadside Emergency
Transporter tie-down procedure
!WARNING:
Avoid body contact with a hot
exhaust pipe when securing the
vehicle to the transporter.
IMPORTANT – Use straps over the
wheels/tyres only, to secure the vehicle to
the transporter.
Caution: Do not use the tie-down
brackets on the vehicle rear
underbody; these are for Jaguar
factory use only. In time, with the
engine switched off, the vehicle body
will drop due to settling of the air
suspension system and cause the tie-
down chains/straps to become slack if
connected to these brackets.
The towing eye is not designed for
securing the vehicle during
transportation. Vehicle failure
The removable towing eye is primarily for
emergency use when towing for SHORT
DISTANCES, e.g. removing the vehicle if it
is causing an obstruct
ion or for winching
the vehicle onto a re covery transporter.
To prevent damage to the automatic
transmission whilst the vehicle is being
towed with the rear wheels on the
ground, towing distance must be
restricted to 0.5 miles (0.8 kilometres).
Towing speed must not exceed 30 mph
(48 km/h).
Always obey towing regulations.
In certain countries the registration
number of the towing vehicle and an
‘ON TOW’ sign or warning triangle must
be displayed in a prominent position at
the rear of the vehicle being towed. When being towed, the gear selector
lever must be in neutral (position ‘N’)
with the ignition key turned to
position ‘II’ to release the steering lock
and render the indicators, horn and
brake lights operational.
!WARNING:
When the engine is not running the
steering and brakes will no longer be
power-assisted.
Therefore, be prepared for relatively
heavy steering and the need for
greatly increased brake pedal
pressure.

Roadside Emergency 6 - 13
Towing Eye
A screw-in towing eye is provided in the
trunk with the jack and can be fitted to
the front or rear of the vehicle.
The towing eye has a left-hand thread
and must be turned in an anti-clockwise
direction when fitting.
Caution:
1. The towing eye is not suitable for ‘solid bar’ towing.
2. Care must be taken to avoid damaging the bumpers and front
apron. Front tow point
The front tow point is located behind a
plastic cover (shown
above) on the left-
hand side of the vehicle, as viewed from
the front.
To remove the cover, unclip the top edge,
pivot down and unclip the bottom edge.
Screw the towing ey e into the vehicle,
right up to the shoulder, turning anti-
clockwise.
To refit the cover (towing eye removed)
first clip the lower edge to the bumper
aperture, pivot up and press the top edge
into position. Rear tow point
!WARNING:
Avoid body contact with a hot
exhaust pipe when fitting the eye to
the rear towing point.
The rear tow point is alongside the left-
hand exhaust pipe.
Screw the towing eye into the vehicle,
right up to the shoulder, turning anti-
clockwise.
