On the Road 4 - 5
Warning Lights
Warning lights are arranged within the
instrument cluster.
There are two warning lights, one red,
the other amber, located above the
message centre for primary and
secondary status of the warnings
displayed by the message centre.
‘RED’ warning lights are for primary
warnings. A primary warning must be
investigated immediately by the driver or
a Jaguar Retailer.
‘AMBER’ warning lights are for secondary
warnings when the driver must take
action and then report the fault to a
Retailer at the earliest opportunity.
Other lights within the instrument cluster
indicate system status, such as blue for
main beam and green for direction
indicators, when in operation. Lamp check
A lamp check is initiated when the
ignition is switched ON and lasts for
three seconds (excepting the air bag
warning light which will remain on for
6seconds). Ifany wa
rning light remains
on after this period, investigate the cause
before driving.
Note: Not all lamps are included in the
lamp check, for example main beam
headlights or direction indicators.
Low Oil Pressure (RED)
This lights up with the ignition
switched ON and should go
out once the engine is running.
If the light remains ON once the engine
has started or comes ON whilst driving,
loss of oil pressure is indicated.
STOP the engine immediately and
investigate the cause.
Caution: Do not restart the engine
until the cause of loss of oil pressure
has been identified and rectified.
First check the engine oil level,
seepage7-6.

Starting/Stopping the
Vehicle
When the vehicle is stationary the
automatic gear selector may be left in ‘D’,
‘ 2 ’, ‘ 3’, ‘ 4’ or ‘ 5’, unless the vehicle is to
be parked. When stopping for traffic
lights, junctions etc., either select ‘ P’ or
apply the parkbrake and select ‘ N’.
Before Starting
Before starting the engine, new owners/
drivers should familiarize themselves with
the layout and operation of the controls
and instruments.
!WARNING:
Before attempting to start the engine,
check parkbrake is ON and gear
selector lever is in position ‘P’ or ‘N’.
To Start the Engine
The engine cannot be started until the
gear selector is in ‘ N’ or ‘ P’.
Insert the key into the ignition switch and
turn clockwise to position ‘II’ to switch
on the ignition.
When the key is turned to position ‘III’
the starter motor will turn the engine
until:
• The key is released and automatically returns to position ‘II’.
• The ignition switch is turned to ‘0’ or ‘I’.
• The gear selector is moved out of ‘P’ or ‘N’.
• The engine starts.
If the engine fails to start, the key must be
turned to position ‘0’ before attempting
to restart.
Do not use the starter continuously for
longer than six seconds. Continued use of
the starter will disc harge the battery and
may damage the starter mechanism.
Wait until the engine stops turning before
re-using the starter.
When the engine starts, release the key. The red charge light and the oil pressure
light in the instrument cluster should go
out when the engine is running.
If the engine fails to start
If an ignition key is placed in the ignition
switch and turned to position ‘II’ and the
alarm security light is flashing, it is
possible that the engine will not start.
In any event, please contact a Jaguar
Retailer to investigate the cause of the
light flashing.
It is possible that the fuel system inertia
switch may have tripped, see page 6 - 3
for the resetting procedure.
If the engine persistent
ly fails to start and
flooding is suspected, depress the
accelerator pedal fully, hold it in this
position and turn the key to position ‘III’
for six seconds. Release the key, remove
your foot from the accelerator pedal and
then attempt to restart the engine.
Note: The engine cannot start whilst the
pedal is fully depressed, it must be
released to enable the engine to start.
If the engine still fail s to start, switch the
ignition OFF and contact a Jaguar
Retailer.

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.

4-60 On the Road
Use of Headlamps In Daylight
When visibility is poor the headlamps
with dipped beam setting should be
switched on so that the vehicle may be
seen more easily by other road users.
The instrument illumination dimmer
control adjusts the brightness of the panel
lighting.
Engine Oil Consumption
A certain amount of oil consumption is
normal. The rate of consumption will
depend on the following:
• The quality and viscosity of the oil.
• The amount of oxidation and dilution of the oil.
• Climatic conditions.
• The speed at which the engine is being operated.
• Road conditions.
Drivers should expect above normal
consumption when the engine is new,
and after running-in if high speeds are
sustained.
Winter Driving
Freeing a frozen door lock
Caution: Do not ap ply a proprietary
lock de-icer through the keyhole.
Should the lock beco me frozen, warm the
end of the key before use.
Windscreen wiper blades
Before driving away, clear any ice from
the windscreen and check that the wiper
blades are free. Switching on the heated
screen will accelerate this process.
The heated wiper park, if fitted, will come
on automatically.
Frost precautions
The correct concentration of coolant
must be maintained at all times when
‘topping up’ or ‘refilling’ the cooling
system.
Parking the Vehicle
When leaving the vehicle, remember the
following:
• Whenever the vehicle is being parked, apply the parkbrake and move the
gear selector to Park ‘P’.
• Do not leave children or pets in the vehicle unattended.
• Do not leave luggage or valuables on view. Always take your valuables with
you or lock them in the luggage
compartment.
• Remove the ignition key and spare keys, even when the vehicle is in your
garage.
• When the vehicle is unoccupied, close
all windows and lock all doors
securely.
• Park the vehicle where it can be seen. At night, park in a well-lit area.
• Ensure that the keys and the key transmitters are removed from the
vehicle before locking the doors,
and that all doors, the luggage
compartment and the hood are
closed.

On the Road 4 - 63
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.

4-66 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.

4-68 On the Road
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.
