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.

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.

Climate Control 5 - 7
To Switch the System On
The climate control system operates in
position ‘II’ (run) of the ignition switch.
With the ignition key turned to the run
position, the system will switch on in the
operating mode last set.
For normal usage select AUTO mode.
AUTO Mode
Automatic operation provides a
controlled environment over a
temperature range of 61°F to 89°F (17°C
to 31°C) and should be regarded as the
normal operating mode.To select automatic climate
control press the AUTO
button; the word AUTO
appears on the LCD screen to confirm
selection.
Select the required temperature.
Front and rear screen heating and timed
air recirculation may be selected in AUTO
mode. Selecting any other control will
cancel AUTO operation.
Automatic operation cannot be
deselected using the AUTO button.
To exit AUTO mode, select another mode
or press the blower control knob to
switch the system off.
Temperature Selection
Separate controls allow
the driver and front
passenger zone
temperatures to be independently
adjusted. Press the red buttons to
increase temperature and the blue
buttons to decrease temperature.
Both driver and front passenger selected
temperatures are always displayed.
Pressing the driver’s buttons to select the
maximum or minimum temperature
settings causes the display to change
to HI or LO respectively and cancel
AUTO mode.
To quickly jump from HI or LO to a
convenient midrange temperature of 73°F
(23°C), press and hold AUTO for a few
seconds.
Dual Temperature Zones
With the DUAL button LED
illuminated, the system provides
separate temperature control of
the driver and front passenger zones.
Press DUAL to deselect dual temperature
control (LED off); the front passenger
temperature will change to that of the
driver side. Using the driver side
temperature control buttons will now
change both zone temperatures together.
To select dual temperature control, press
either the DUAL button or one of the
front passenger side red/blue
temperature control buttons. The DUAL
LED is illuminated.
External Temperature
The external (EXT) temperature is
displayed at the top of the screen.
Fahrenheit/Celsius Selection
Press the button to change the
scale between degrees
Fahrenheit (°F) and degrees
Celsius (°C) for the displayed
internal and external (EXT)

switching off front climate control (above)
will also cause the rear climate control
system to be switched off. Switching the
front system on again will not switch the
rear system on.
Ram Air
With the climate control system switched
off, air recirculation is automatically
selected (intake flap closed). To select
fresh air with the system off, press the
MODE button to select one of the air
distribution modes.
With the blower switched off, the fresh
airflow results from the forward motion
of the vehicle (ram air effect).
Smog sensing
Where fitted, the smog sensor detects
road traffic pollutants and automatically
selects air recirculation when the level of
pollution outside the vehicle reaches a
certain level. The level of pollution at
which the smog sensor will respond can
be adjusted.
Once the level of pollutants decreases,
air recirculation will switch off (subject to
the normal operation of the automatic
climate control system).
To adjust smog sensitivity: Press the
air recirculation and AUTO buttons
simultaneously. The display will show a
number between 0 and 5: 0 indicates
that the smog sensor is switched off, and
5 shows that the sensor is set to its most
sensitive setting. Use the driver’s
temperature control bu ttons to increase
or decrease the smog sensitivity.
Caution: Don’t set the smog sensor to
a needlessly high level in cold and
damp conditions: This could result in
interior condensation.

Roadside Emergency 6 - 3
6 Roadside Emergency
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.

6 - 12 Roadside Emergency
Transporter tie-down procedure
!WARNING:
Avoid body contact with a hot
exhaust pipe when securing the
vehicle to the transporter.
IMPORTANT – Use straps over the
wheels/tyres only, to secure the vehicle to
the transporter.
Caution: Do not use the tie-down
brackets on the vehicle rear
underbody; these are for Jaguar
factory use only. In time, with the
engine switched off, the vehicle body
will drop due to settling of the air
suspension system and cause the tie-
down chains/straps to become slack if
connected to these brackets.
The towing eye is not designed for
securing the vehicle during
transportation. Vehicle failure
The removable towing eye is primarily for
emergency use when towing for SHORT
DISTANCES, e.g. removing the vehicle if it
is causing an obstruct
ion or for winching
the vehicle onto a re covery transporter.
To prevent damage to the automatic
transmission whilst the vehicle is being
towed with the rear wheels on the
ground, towing distance must be
restricted to 0.5 miles (0.8 kilometres).
Towing speed must not exceed 30 mph
(48 km/h).
Always obey towing regulations.
In certain countries the registration
number of the towing vehicle and an
‘ON TOW’ sign or warning triangle must
be displayed in a prominent position at
the rear of the vehicle being towed. When being towed, the gear selector
lever must be in neutral (position ‘N’)
with the ignition key turned to
position ‘II’ to release the steering lock
and render the indicators, horn and
brake lights operational.
!WARNING:
When the engine is not running the
steering and brakes will no longer be
power-assisted.
Therefore, be prepared for relatively
heavy steering and the need for
greatly increased brake pedal
pressure.

7-22 Maintenance
Vehicle Care
Valet kit
A valet kit containing a selection of Car
Care products is available from the Jaguar
accessory range.
Interior Care
Brush and clean the interior regularly.
Use a vacuum cleaner where possible to
remove all dust from the interior and
trim.
Carpets
Marks or stains can be removed by gentle
scrubbing with a weak solution of soap
and warm water.
For more stubborn stains a commercially
available carpet cleaner should be used.
See your Jaguar Retailer for advice.
Headlining
Remove dust in the headlining with a
vacuum cleaner. To remove stains,
dab gently without pressing, using a
fluff-free white cloth, moistened with
Jaguar Upholstery Cleaner.
Do not use methylated spirit or solvents
as this may cause damage or
discoloration to the headlining.Leather upholstery
Dust and dirt can penetrate the pores and
creases of leather, causing surface wear
and brittleness. To prevent ingrained dirt,
inspect the seat upholstery regularly and
clean every one to two months as follows:
• Wipe the seat surfaces with a clean,
damp, non-coloured cloth, changing
frequently to a clean area of cloth.
Avoid over-wetting.
• If this is not sufficient, use a cloth which has been dampened with warm
soapy water and then wrung out;
avoid over-wetting. Use only mild
non-caustic soap.
• Use Jaguar Leather Cleaner for heavily soiled areas.
• Dry off and rub with a clean soft cloth, changing su rfaces regularly.
When staining (e.g. from clothing) or
spillages occur, clean the affected area
immediately as described above. Note:
Do not use solvents such as petrol
(gasoline), white spirit or alcohol. Do not
use detergents, furniture polish or
household cleaners. Although such
treatments may give, initially,
an impressive appearance, their use will
lead to rapid damage or deterioration of
the leather, and will not be covered by the
Manufacturer’s Warranty. Unless spillages
such as tea, coffee or ink are washed away
immediately, permanent staining may
have to be accepted.
If a valeting service is used, ensure that
the specialist firm concerned is aware of
these instructions, and they follow them
precisely.
