Instruments
None of the instruments will show
correct indications until the ignition is
switched ON (position ‘II’).
If the exterior light switch is ON and the
ignition is ON, the display brightness can
be varied using the dimmer switch
(page 4 - 25).
Tachometer (A)
The tachometer indicates engine speed in
revolutions per minute and is calibrated
in increments of 250 rev/min extending
to 8000 rev/min (to 7000 rev/min for
supercharged vehicles).
Caution: Do not allow the needle to
enter the red sector.
Speedometer (B)
Speed indication is in either:
USA– Miles per hour, the outer figures,
and kilometres per hour on the inner
ring.
Canada and Mexico – Kilometres per
hour, the outer figures, and miles per
hour on the inner ring,
Odometer (C)
Records the total distance covered by the
vehicle.
The odometer reading is displayed below
the speedometer, al ong with the trip
distance since it was last reset. To reset
the trip distance, press the reset button
on the trip computer switchpack. The trip
distance will roll-over at 9999.9 miles
(or 16,090 kilometres).
The odometer is displayed in the message
centre unless a message has priority or a
trip computer function has been selected.
Fuel Level Gauge (D)
Indicates the amount of fuel in the tank.
A warning light is displayed in the gauge
when the fuel in the tank is at a low level.
The tank should be refilled at the earliest
opportunity.
The small arrow, shown beside the fuel
pump symbol, identifies on which side of
the vehicle the filler cap is located.

4-64 On the Road
When filling, the dispenser nozzle must
be inserted into the filler neck sufficiently
to open the trap door for fuel to flow into
the fuel tank. For quickness and to
completely fill the ta nk, ensure that the
fuel nozzle rests on the filler neck as
shown. Fill the tank until the filler nozzle
automatically shuts off. Filling beyond
this point could result in fuel spillage.
After refuelling, refit the fuel filler cap in
to the filler neck, twist the filler cap
clockwise until it clicks and close the flap,
which automatically locks shut. The continuous use of high quality fuel
makes the need for a
dditional additives
unnecessary.
This will help to protect the engine
components against corrosion, carbon
deposit formation and prevent the fuel
injection system from clogging.
If in doubt your local Jaguar Retailer will
advise on which fuel must be used in
your vehicle.
Fuel requirements
The filler neck of the fuel tank is a small
diameter to suit the unleaded fuel pump
nozzle and will prevent the larger
diameter leaded fuel nozzle from entering
the filler neck.
Note: Not all countries have a small
diameter nozzle, for example, Japan,
so care must be taken to only fill the tank
with unleaded fuel.

Catalytic Converters
A few precautions on the use of vehicles
fitted with catalytic converters are
necessary. These are:
1. In order to maintain the efficiency of the emission control system it is
essential that unleaded fuel is used.
Use of leaded fuel will seriously
damage the catalytic converters.
2. Heavy impact on the converter casings must be avoided.
3. The engine settings must not be altered; they have been established to
ensure that the vehicle will comply
with stringent exhaust emission
regulations. Incorrect engine settings
could cause unusually high catalytic
converter temperatures and thus
result in damage to the converter and
vehicle. If adjustment to the settings is
considered necessary, this should be
performed by a Jaguar Retailer. 4. A correctly tuned engine optimises
exhaust emissions, performance and
fuel economy and it is recommended
that the vehicle is regularly
maintained.
5. Do not continue to operate the vehicle if any engine malfunction is evident;
malfunctions should be rectified
immediately. For instance, misfire,
loss of engine performance, excessive
oil consumption or engine run-on may
lead to unusually high catalytic
converter temperatures and may
result in damage to the converters and
vehicle.
6. The use of catalytic converters increases exhaust system
temperatures, therefore, do not
operate or park the vehicle in areas
where combustible materials such as
dry grass or leaves may come into
contact with the exhaust system. 7. Do not run the engine with either a
spark plug lead disconnected or a
spark plug removed. Do not use any
device that requires an insert into a
spark plug hole in order to generate air
pressure e.g. tyre pump, paint spray
attachment etc., as this could also
result in catalyti c converter damage.
8. The vehicle is designed for normal road use. Below are examples of abuse
which could damage the catalytic
converters and vehicle. These may
lead to a dangerous condition due to
excessively high catalytic converter
temperatures.
• Competition or off-road use.
• Excessive engine speed.
• Overloading the vehicle.
• Switching off the engine whilst in gear.

Inertia Switch
In the event of an accident, the inertia switch may trip
(depending on the severity an d type of impact), isolating
operation of the fuel pump. Once the switch has tripped it must
be reset before attempting to restart the engine.
The inertia switch is located behind the trim on the left-hand
side of the vehicle, forward of the front door post, below the
fascia. A finger access hole in the trim allows the driver to reset
the switch.
Resetting the Switch
!WARNING:
To avoid the possibility of fire or personal injury, do not
reset the inertia switch if you see or smell fuel.
If no fuel leak is apparent, reset the inertia switch as follows:
1. Turn the ignition switch to position ‘0’.
2. Press down the red reset butt on on the top of the inertia
switch.
3. Turn the ignition switch to position ‘II’, pause for a few seconds, then return the key to position ‘0’.
4. Make a further check for fuel leaks.
