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.

Engine Temperature (E)
Drive at moderate road and engine
speeds until normal operating
temperature is reached. This is indicated
when the pointer is between the
blue (cold) segment and the red (hot)
segment.
The engine operating temperature will
vary with changes in weather and engine
load. The engine temperature may rise in
some circumstances, such as:
• Idling for long periods in slow moving traffic.
• Driving up a long hill in hot weather.
• Driving slowly or stopping after driving at high speed.
• Towing a trailer or caravan.!WARNING:
1. The radiator cooling fans may continue to run after the ignition
has been switched off but will
automatically switch off when the
engine has cooled sufficiently.
2. It is unsafe to run the engine in an overheated condition.
3. Do not remove the coolant reservoir filler cap while the
engine is hot. If it is essential, then
protect your hands against
escaping steam. SLOWLY turn the
cap anti-clockwise to allow the
steam pressure to escape
completely before removing the
cap. Should the pointer move into the red
segment (
H) of the coolant gauge, stop
the vehicle as soon as it is safely possible,
turn off the engine and open the hood to
allow the engine to cool.

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.

Fuel and Refuelling
Before refuelling, switch off the ignition
and remove the key.
Note:Do not leave the ignition key in the
vehicle; vehicles have been stolen from
garage service/filling stations whilst the
driver is absent from the vehicle. It is
recommended that the vehicle is locked,
if left unattended.
Caution: No additives of any kind
(fuel or oil) must be put into the fuel
tank. Additives could reduce engine
life or affect exhaust emissions.
!WARNING:
1. Fuel vapour is highly flammable and in confined spaces is
explosive and toxic. In the event
of inadvertent spillage, and before
refuelling, always switch OFF the
engine. Do not use exposed flame
or light. Do not smoke. Do not
inhale fumes.
2. Do not fill the tank so that fuel is visible in the fuel filler intake
tube. This could cause spillage
and danger from exposed fuel.
Fuel Tank Filling
Caution: Your vehicle is fitted with
catalytic converters and must only be
filled with ‘Unleaded Fuel’.
The fuel filler flap release switch is
located in the knee bolster switchpack
below the fascia. The fi ller flap is on the
right-hand side of the vehicle.
A small arrow is shown on the fuel gauge
as a reminder on which side of the
vehicle the fuel filler flap is located. Open the fuel filler flap and turn the filler
cap anti-clockwise, a ¼ turn until
resistance is felt. Continue turning to
release the cap from the filler neck.
The cap is held by a retaining strap and
can be stowed over the hook on the flap
to allow easy access to fill the tank.
A warning label on the inside of the fuel
filler flap advises type/grade of fuel.

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.

4-66 On the Road
Fuel filler flap manual release
If the fuel filler flap fails to release it can
be manually unlocked as follows:
1. In the luggage compartment, remove
the carpet from the right-hand side,
behind the rear light. To do this, turn
the carpet securing screws a ¼ turn
and then firmly pull the top corner of
the carpet down.
2. Locate the fuel flap release mechanism and pull the knob rearwards. This will
release the flap to gain access to the
filler cap and enable the vehicle to be
refuelled.
3. Report the fault to a Jaguar Retailer. Unleaded fuel
All vehicles are fitted with a catalytic
system and can only use unleaded fuel.
Unleaded fuel must be used for the
emission control system to operate
properly. Its use will also reduce spark
plug fouling, exhaust system corrosion
and engine oil deterioration.
The preferred fuel should have an octane
rating of at least 95 RON (Research
Octane Number).
‘Super Green’ Plus 98 RON unleaded fuel
(where available) may be used as an
alternative to the standard 95 RON
unleaded fuel. Some countries have only 91 RON fuel
available. The vehicles in these countries
are specially calibrated to use this fuel.
Using unleaded fuel with an octane rating
lower than recomm
ended can cause
persistent, heavy ‘spark knock’ (a metallic
rapping noise). If severe, this can lead to
engine damage.
If a heavy ‘spark knock’ is detected even
when using fuel of the recommended
octane rating, or if you hear steady ‘spark
knock’ while holding a steady speed on
level roads consult a Jaguar Retailer to
have the problem corrected. Failure to do
so is misuse of the vehicle, for which
Jaguar Cars Limited, is not responsible.
However, occasional light ‘spark knock’
for a short time while accelerating or
driving up hill, may occur.
Emission control components
Owing to the legislative requirements or
options available in some countries,
a Jaguar Retailer should be consulted
where any doubt exists as to the precise
emission control system specification of
this vehicle.

7 - 6 Maintenance
Checking and Top Up
Check Engine Oil Level
Check the oil level regularly with the vehicle on flat, level
ground.
Refer to page 7 - 5 for dipstick and oil filler locations.
It is preferable to check the oil level after the vehicle has been
standing, that is, with th e engine completely cold.
If the engine has been started do not check the oil level until the
engine has reached normal operating temperature. Stop the
engine and wait for a minimum of 5 minutes to allow the oil to
drain back into the sump.
Remove the dipstick ( A) and wipe clean with a non-fluffy cloth.
Replace fully, then wi thdraw the dipstick. If the oil level is above
the lower of the two dots on the dipstick then no additional oil
is required.
If the oil level reaches the lower of the two dots, remove the oil
filler cap ( B) and add oil, to the quantity and specification
shown on the next page.
Refit the filler cap and hand tighten securely.
Caution: Do not use oil additives of any type. Use only
specified lubricants.
