ABS Monitoring
The ABS control module monitors the
ABS electrical system from ignition switch
ON to ignition switch OFF.
Any malfunction will be indicated by the
anti-lock warning light coming on.
Should a fault develo p in the ABS system,
the brake system will still operate
conventionally and with the same
standard of performance as vehicles not
equipped with ABS.
Caution: Consult a Jaguar Retailer
immediately if the warning light
comes on while driving, a system
failure is indicated.
Advice on ABS Braking
Techniques
For optimum ABS performance the
instructions on braking techniques during
ABS operation should be followed:
1. Do not release brake pressure when the pulsating effect is felt. Maintain a
constant pressure until the manoeuvre
is completed. 2. To familiarise yourself with the feel of
the brake pedal duri ng ABS braking,
practise an emergency stop
procedure, always making sure it is
safe to do so. With the seat belts fitted
to all occupants, drive the vehicle at
20 mph (32 km/h) and brake sharply.
3. ABS enables the driver to steer around obstacles during emergency braking.
However, the consequ ences of turning
sharply at high speed cannot be
overcome by the ABS.
4. Do not attempt to ‘pump’ the brakes to avoid skidding as this can interfere
with the ABS operation. The ABS will
not allow the wheels to skid under
normal road conditions.
5. The ABS will tend to keep the vehicle straight during braking. Because
braking distances may increase under
certain road conditio ns, it is necessary
to plan and make turning manoeuvres
as early as possible.
Emergency Brake Assist (EBA)
The EBA system measures the rate at
which the brake pressure increases.
If the system detect s an emergency
braking situation, EBA automatically
initiates the full br aking effect. This can
reduce stopping distances in critical
situations, which can help an
inexperienced driver to stop in the same
distance as an experienced driver.
!WARNING:
The EBA system is an additional safety
system: it is not intended to relieve
the driver of his responsibility for
exercising due care and attention
when driving.

Forward alert
Limited detection and warning of objects
ahead is provided during ACC operation
by the ACC ‘DRIVER INTERVENE’
warning.
The forward alert feature additionally
provides warnings whilst ACC is not
engaged, if an object is detected close
ahead then a warning tone and message
will be issued. The brakes will not be
applied.
This additional feature may be switched
on or off using the forward alert switch in
the lower outboard knee bolster
switchpack. When the indicator lamp in
the switch is on, forward alert is active.The sensitivity of the warning may be
changed:
• Pressing the gap decrease button
when ACC is disengaged displays and
then decreases the sensitivity of the
alert.
• Pressing the gap increase button displays and then increases the
sensitivity of the alert.
Both of these are accompanied by the
FORWARD ALERT message on
the message centre.
ACC failure
If a fault occurs during operation of the
system in cruise or follow modes,
the ACC system will switch OFF and
cannot be used until the fault is cleared.
A red warning light and the message
‘DRIVER INTERVENE’ appear briefly, and
are then replaced by an amber warning
light and the message ‘CRUISE NOT
AVAILABLE’.
If failure of the ACC or any related system
occurs at any other time an amber
warning light will be displayed
accompanied by th e message ‘CRUISE
NOT AVAILABLE’. It will not be possible
to activate the ACC system in any mode. Accumulations of dirt, snow or ice on the
on the sensor or cover may inhibit ACC
operation. Fitting of a vehicle front
protector or metallis
ed badges may also
affect ACC operation.
If this occurs in ACC cruise/follow mode,
the red warning light is displayed,
the audible alarm sounds and the
message ‘DRIVER INTERVENE’ appears
briefly. These warnings are then replaced
by the amber warning light and the
message ‘ACC SENSOR BLOCKED’ is
displayed. The system is no longer active.
Clearing the obstruction allows the
system to return to normal operation.
If the obstruction is present when ACC is
inactive, e.g. on initial starting or with the
ACC system switched off, the amber
warning light will be displayed with the
message ‘ACC SENSOR BLOCKED’.
Tyres other than those recommended
may have different sizes. This can affect
the correct operation of the ACC.

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.

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.

5 - 4 Climate Control
In AUTO mode, the air intake flap is
controlled automatically. If required,
air recirculation may be manually
selected for either a short or indefinite
period.
Air Recirculation
Timed air recirculationPress the button briefly to select
timed air recirculation.
The fresh air intake is opened
and the button LED extinguished at the
end of the time out period.
Latched air re circulation
Press and hold the button for a
few seconds to select latched air
recirculation. Selection is
indicated by the scre en symbol and two
beeps.
Selecting latched air recirculation cancels
AUTO operation.
To deselect latched air recirculation,
press the recirculat ion button again,
or select AUTO.
!WARNING:
To prevent humidity build up inside
the vehicle and possible screen
misting, avoid driving with the air
conditioning system off or with
manual air recirculation selected for
prolonged periods.
General Points
To ensure the satisfactory operation of
the climate control system, note the
following points:
• Ensure that the external grille at the base of the windscreen, which
provides fresh air for the climate
control system, is kept clear of leaves,
snow or obstructions.
• A solar sensor is mounted on the centre top of the fascia, as shown
opposite ( A) . E n s u r e t h a t this sensor is
not covered.
• Temperature and humidity sensors are located behind the small grille ( B).
Do not cover or obstruct the opening.
• Air ducts under the front seats supply the rear passenger footwells (see
illustration opposite). Objects or
material placed under the seats may
block or obstruct the open ducts. • The external air intake to the air
conditioner/heater system is fitted
with a filter. Ensure that the filter is
changed at the specified service
intervals to maintain efficient
operation.
• If the air conditioning system is not used frequently, it should be run
briefly at least once each week, with a
cold setting, to prevent the seals from
drying out with subsequent
refrigerant leaks.
• Moisture removed from the air by the air conditioning unit is discharged
onto the road underneath the vehicle.
After stopping, puddles of water may
form underneath the vehicle.
Air Distribution
The illustration opposite shows the
location of the air vents within the
vehicle. The airflow from the fascia face
level vents is regulated using thumbwheel
controls and adjustable direction vanes.
Air distribution between the windscreen,
fascia and floor levels is selected
automatically when operating in AUTO
mode but can be selected manually.

Roadside Emergency 6 - 7
Locking Wheel Nuts
Where Jaguar locking wheel nuts are
fitted (one on each wheel), they can only
be removed using the correct key socket.
The locking wheel nut comprises two
grooved parts, front and rear, which must
be turned together to allow the nut to be
fitted or removed.
To remove the nut, the front and rear
grooves must be aligned. Locate the key
socket in the grooves and push it fully
over both parts of the nut. Fit the wheel
nut wrench over the key socket and
loosen the locking wheel nut (turn anti-
clockwise). Attempting to remove the nut without the
correct key socket
(such as attempted
theft) or with the socket not located over
the rear part of the nut, will cause the
front part only ( A) to turn.
If this has happened, rotate the front part
with the key socket until the grooves are
re-aligned and then push the socket fully
over the nut.
Should a new key socket be required,
contact your Jaguar Retailer. Proof of
vehicle ownership will be required.
