2004 JAGUAR XJ brakes

On the Road 4 - 59
General Driving
Information
!WARNING:
Ensure the parkbrake is on and the
automatic gear selector is in
position ‘P’ or ‘N’ before attempting
to start the engine.
Before driving off, check the gauges and
warning lights and messages. Take special
note of any warning light that is on.
Seat belts are provided for your safety
and it is unwise, and in certain countries
illegal, to commence any journey,
however short, without wearing them.
Warming Up
Do not operate the en gine at high speed
when first started but allow time for the
engine to warm up and the oil to
circulate.
Engine Braking On Downhill
Gradients
When driving on mountain roads with
long downhill gradients it is advisable to
select a low gear.
Running-in
Apart from a few precautionary
recommendations, there are no strict
‘running-in’ procedures for this vehicle.
By observing the following advisory notes
you will ensure maximum engine,
transmission and brake life for your
vehicle:
1. Allow the engine to warm up thoroughly before operating at engine
speeds over 3500 rev/min.
2. Vary the speed frequently.
3. From 940 miles (1500 kilometres) onwards, gradually increase
performance of the vehicle up to the
permitted maximum speed, where
road conditions permit. Running-in for brakes
To ensure that the brake pads can
‘bed-in’ evenly and reach their optimum
wear and performance condition, usually
within 300 miles (480 kilometres),
the following points are recommended.
1. Where possible, avoid heavy braking
or rough usage of the brakes as this
can result in damage being caused to
the brake pads and discs.
2. Avoid prolonged use of the brakes, for example, when descending severe
gradients.
3. Frequent light application of the brakes is desirable. This helps to fully
‘bed-in’ the brake pads before the
normal running-in period is
completed and the vehicle is operated
at high speeds, when maximum brake
efficiency will be required.
The above equally applies when new
discs or pads have been fitted.

4-62 On the Road
Towing a Trailer
Your Jaguar Retailer, and the main
motoring organisations can advise you on
towing, towing weight capacities and
about regulations that apply in other
countries.
The following are important points of
safety, stability and comfort upon which
further advice should be sought:
• Maximum braked towing weight is permissible, provided long periods of
uphill driving on gradients over 8%
are not undertaken.
• In high altitude mountainous regions, the thinner atmosphere can reduce
engine performance. Above 3280 feet
(1000 metres) the stipulated
maximum permitted gross train
weight must be reduced by 10% for
every 3280 feet (1000 metres) in
altitude.
• The kerbside weight of the vehicle can be found on page 8 - 4.
• When towing at the maximum permissible rear axle load keep within
legal towing speeds but in any case do
not exceed 62 mph (100 km/h). • Tyres must be inflated to the normal
(higher) pressures shown on the tyre
pressure label on the fuel filler flap.
• The recommended maximum tow-ball nose weight is shown
on page 8 - 5. Having a lower nose
weight or exceeding the maximum
nose weight limit may impair the
vehicle’s handling.
• When towing, the nose weight of the trailer and the tow-bar assembly must
be deducted from the permissible
maximum load, see page 8 - 5.
• Avoid heavy braking. As the overrun brake on the traile r is not connected
to the ABS, heavy trailer braking
could critically affect the stability of
the outfit as a whole.
• Ensure that the towing vehicle’s engine, transmission, suspension,
brakes and tyres are fully efficient and
regularly serviced. Similarly check the
wheels, tyres, brakes and wheel
bearings of the trailer. Caution:
1. When not in use, it is
recommended that the removable
tow-ball is either securely stowed
in the luggage compartment or,
preferably, not in the vehicle.
Do not leave it loose in the
vehicle.
2. It is essential that only a Jaguar tow-bar and Jaguar electrical tow-
bar kit are supplied and fitted by a
Jaguar Retailer. Contact your
Jaguar Retailer for details of
additional parts that are advised
to be fitted before towing. This is
particularly important with this
vehicle having air suspension.
If unapproved towing equipment
is used whilst towing, the air
suspension speed lowering
function will not be inhibited.
This may result in a change in
trailer weight distribution and
attitude.

6 - 4 Roadside Emergency
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 - 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.
