Tyre pressure warning with speed
If the vehicle is to be driven at speeds in excess
of 160 km/h (100 mph), the tyre pressures
should be increased as stated in this handbook
or on the placard label. Failure to increase the
tyre pressures and driving in excess of
160 km/h (100 mph), will illuminate the yellow
warning telltale and display a text message
TYRE PRESSURES LOW FOR SPEED . In the
event of this warning be ing displayed, vehicle
speed should be reduced
Temporary use spare wheel and tyre
change
If the temporary use spare wheel is fitted the
system will automatically recognise the change
in wheel positions. The n after approximately
ten minutes of driv ing above 25 km/h
(18 mph), a message TYRE NOT MONITORED
will be displayed accompanied by illumination
of the warning telltale and the corresponding
block in the vehicle graphic.
The warning telltale will initially flash and will
subsequently revert to continuous illumination.
Extended use of the temporary use spare wheel
will produce an additional text message TYRE
PRESSURE SYSTEM FAULT .
This TPM system display sequence will be
activated at every ignition cycle until the
temporary use spare wheel is replaced by a
fully operational full size wheel and tyre
assembly.
Always replace the temporary use wheel before
having TPM system faults investigated. The
fault may well be rectified with the fitment of a
fully operational full size running tyre in lieu of
the temporary use spare wheel assembly.
Tyre changing
Always have your tyres serviced or changed by
a qualified engineer.
Care must be taken to avoid contact between
the bead of the tyre and the sensor during
removal and refitting of the tyre, otherwise the
sensor may become damaged and or
inoperable.
Sensors can be removed from the wheel by the
unscrewing of the va lve retention nut.
Replacement sensor
Should the sensor require replacing, it should
be carried out by a Dealer/Authorised Repairer.
A replacement sensor must be fitted to a
running wheel in order to be recognised by the
system. The vehicle needs to be stationary for
15 minutes during the se nsor fitment before
the system is ready to detect the new sensor.
The vehicle must be driven for a minimum of
fifteen minutes after the sensor change, and
then remain stationary for fifteen minutes to
activate full TPM system operation.
If the TPM system warning for any wheel does
not clear, even after ensuring correct inflation
and driving for more than ten minutes above
25 km/h (18 mph), you should seek qualified
assistance as soon as possible.
CAUTION
Valve stem seal, washer, nut, valve core
and cap should be replaced at every tyre
change. Valve stem seal, washer and nut must
be replaced if valve re tention nut is loosened.
Sensor units and nuts must be refitted using
correct torque figures and associated profile.
Damage to the vehicle may result if these
precautions are not taken.

Fuses

CHANGING A FUSE
Note: Jaguar recommend that owners do not
remove or replace rela ys. It is recommended
that you seek qualified assistance in the event
of a rela y failure.
Always switch off the i gnition and the affected
electrical circuit, be fore replacing a fuse.
Fuse failure is identifi ed by an inoperative
circuit.
A special tool for remo ving and replacing Mini
fuses is provided in the engine compartment
fuse box, together with spare fuses. Two types of fuses are fitted in the fuse boxes:
1.
Mini-type
2. J-Case
If a spare fuse is used, renew it (or have it
renewed) with a fuse of the same amperage
rating.
Push the tool onto the suspect fuse and
withdraw it.
If the wire in the fuse is broken, the fuse has
blown.
Fit a new fuse using the tool.
Checking or renewing a blown fuse
J-Case fuses ( 2) and relays should only be
replaced by a qualified technician.
Fuses are colour coded according to the
amperage and the rating is also marked on
each fuse.
CAUTIONS
Always turn off the ignition system and
the affected electrical circuit, before
replacing a fuse.
Fit Jaguar approved replacement fuses
of the same rating and type, or fuses of
matching specification. Using an incorrect
fuse may result in damage to the vehicle's
electrical system, and can result in a fire.
No attempt should be made to repair a
fuse that has blown.
If the replacement fuse blows after
installation, the system should be
checked by your Dealer /Authorised Repairer.

Status after a collision

DRIVING AFTER A COLLISION
Before starting or driving
If the vehicle has been involved in an accident
it should be checked thoroughly before
attempting to start the engine or drive the
vehicle.
Check for:-
• Fuel leaks.
• Fluid leaks.
• Battery damage.
• Damage to wiring.
• Damage to lights.
• Damage to steering, suspension, wheels
or tyres.
• Sharp or protruding bodywork.
• Operation of doors and locks.
• Condition and operation of seat belts and
SRS components.
• Activation of the pe destrian protection
system.
• Condition of chil d seats and their
mounting/attach ment points.
Note: This list is not exhaustive.
Resetting the fuel cut-off
The fuel system cut-off forms part of the Safety
and Restraint System (SRS) fitted to your
vehicle. Following an impact, and depending on
the severity, the fuel pump may be switched
off.
1.Switch the ignition off, and wait for 10
seconds.
2. Without pressing the brake pedal, press
the engine START/STOP button, to switch
the electrical circuits on. Wait for 30
seconds.
3. Check the vehicle thoroughly for fuel leaks.
If a leak is detected switch the ignition off
immediately.
•The vehicle must not be started if a leak
is present. Seek qualified advice, and
have the vehicle recovered.
4. If no leaks are detected, start the engine.
WARNING
If the vehicle is involved in a collision
it should be checked by a Dealer/
Authorised repairer, or suitably
qualified personnel, before starting or driving.
WARNING
The fuel cut-off should never be reset
if you can smell fuel, or a leak can be
seen. Doing so can lead to a fire
which may cause personal injury or death.

Vehicle recovery
256

TOWING THE VEHICLE ON FOUR
WHEELS
Note: The recommended recovery method is
to raise all four wheels.
Towing procedure
1. The vehicle should be parked on firm level
ground, with the parking brake on, and the
gear selector in P (Park).
2. Secure the towing attachment from the
recovery vehicle to the front towing eye.
See TOWING POINTS (page 253).
3. Dock the Jaguar Smart Key and switch on
the ignition. See GENERAL INFORMATION
(page 132). 4.
Apply the foot brake and release the
parking brake.
5. With the foot brake st ill applied, activate
the Emergency Park Release (EPR).
See TRANSPORTING THE VEHICLE
(page 254).
6. The vehicle can now be towed a maximum
of 0.8 km (0.5 miles) at a maximum speed
of 48 kmh (30 mph).
7. Upon arrival at the destination, ensure
wherever possible that the vehicle is
parked on firm level ground.
8. Lower the Emergency Park Release (EPR)
lever, to cancel EP R and to re-engage P
(Park).
9. Apply the parking brake.
10. Switch off the ignition and remove the
Jaguar Smart Key.
11. Remove the towing attachment from the
towing eye.
WARNINGS
Ensure that the remote control
remains docked whilst the vehicle is
being towed. Removing the remote
control will engage the steering lock, which
will prevent the vehicle from steering
correctly.
If the engine cannot be run whilst the
vehicle is being towed, there will be
no power assistance for the steering
or brakes. This will result in greater effort
being required to steer or slow the vehicle, and
greatly increased stopping distances.
CAUTIONS
The vehicle should only be towed in a
forward direction with all four wheels on
the ground.
The vehicle should only be towed for a
maximum of 0.8 km (0.5 miles), at a
maximum speed of 48 km/h (30 mph). Towing
for a greater distance or at a higher speed, may
result in serious damage to the transmission.
CAUTION
Leaving the ignition switched on for
extended periods will cause the battery
to drain.
WARNING
Use extreme caution when detaching
towing equipment. Vehicle movement
is possible which can result in serious
injuries.
