Jaguar fully supports all efforts to protect
and maintain ambient air quality and
encourages the use of reformulated
gasoline, where available.

CATALYTIC CONVERTERS

!

WARNING:

Exhaust system temperatures can be
extremely high - DO NOT park on
ground where combustible materials
such as dry grass or leaves could come
into contact eith the exhaust system -
in dry weather as a fire could result.

Caution: Catalytic converters can be
easily damaged through improper use,
particularly if the wrong fuel is used, or
ifan engine misfire occurs. For this
reason it is VERY IMPORTANT that you
heed the precautions which follow:
• In order to maintain the efficiency of

the emission control system it is
essential that the correct fuel is used.
If the vehicle is fitted with a gasoline
engine, never refuel with leaded fuel:
this will seriously damage the catalytic
converters.

• Heavy impact on the converter

casings must be avoided.

• A correctly tuned engine optimises

exhaust emissions, performance and
fuel economy. It is recommended that
the vehicle is regularly maintained.

• 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 Dealer.

• 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.

• Do not run a gasoline 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. tire pump, paint
spray attachment etc., as this could
also result in catalytic converter
damage.

• The vehicle is designed for normal

road use. Below are examples of
abuse which could damage the
catalytic converters and vehicle:

Competition or off-road use.

Excessive engine speed.

Overloading the vehicle.

Switching off the engine whilst in
gear.

These may lead to a dangerous
condition due to excessively high
catalytic converter temperatures.

WARNING:

Do not disconnect any pipes in the air
conditioning refrigeration system. A
refrigerant is used which can cause
blindness if allowed to contact the
eyes. If refrigerant should contact the
eyes or skin, wash the eyes or affected
area with cold water for several
minutes. Do not rub. As soon as
possible thereafter, obtain treatment
from a doctor or eye specialist.

INTRODUCTION

The cabin is supplied with filtered air from
a fully automatic electronic climate
control system, which also provides
individual selection of temperature (dual
zone) by the front occupants.

The system can be overridden by manual
controls.

The climate control panel is located in the
center console above the radio and audio
controls. There are two variants:
• A dedicated control panel with LCD

(Liquid Crystal Display) screen, refer
to page 152.

• A multi-function touch control and

display unit, shared with navigation
and other systems (see the
touch-screen display handbook).

RECOMMENDED OPERATION

Automatic climate control

Automatic climate control provides
efficient regulation of the vehicle
environment without constant
adjustments from the occupant.

Sensors inside the vehicle monitor
temperature, humidity and direct sunlight.
In response, the electronic control system
automatically adjusts the heat output,
blower speed, air intake and airflow
distribution, so as to maintain the
selected temperature(s) and reduce
misting.

Automatic operation provides optimum
comfort under most driving conditions.

It is recommended that automatic
control (AUTO) is selected as the
normal operating mode.

Use of air conditioning

Air conditioning is an integral part of the
climate control system, providing cooled
and dehumidified air for occupant
comfort; the dry airflow is also effective in
preventing misting of the windows.

While the air conditioner can be manually
switched off, it is recommended that it is
used in all climatic conditions throughout
the year, preferably in AUTO mode.

Close all windows and the sunroof when
the air conditioning is on to ensure
satisfactory operation.

Note: When air recirculation is selected,
the sound of the airflow will change: this is
normal.

Use of air recirculation

The air conditioner and heater system is
supplied with fresh air via an intake flap.

Closing the flap causes the air inside the
vehicle to be recirculated. This helps to
prevent unpleasant odours from being
drawn into the vehicle and also to improve
the performance of the air conditioner in
very hot conditions. However, the use of
recirculated air will cause screen misting
after a short period and should only be
used as necessary.

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.

!

WARNING:

To prevent humidity build up inside the
vehicle and possible screen misting,
avoid driving with the air conditioning
system off, or in manual air
recirculation, for prolonged periods.

GENERAL POINTS

To make sure of the satisfactory operation
of the climate control system, note the
following points:
• Make sure that the external grille at

the base of the windshield, which
provides fresh air for the climate
control system, is kept clear of leaves,
snow or obstructions.

• A solar sensor is mounted on the

center top of the facia, (as shown on
the next page) (1). Ensure that this
sensor is not covered.

• Temperature and humidity sensors

are located behind the small grille (2),
(as shown on the next page). Do not
cover or obstruct the opening.

• Air ducts under the front seats supply

the rear passenger footwells (as
shown on the next page). Objects or
materials placed under the seats may
block or obstruct the open ducts.

• The external air intake to the air

conditioner and heater system is fitted
with a filter. Make sure 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. This is
normal.

AIR DISTRIBUTION

The illustration above shows the location
of the air vents within the vehicle. The
airflow from the facia face level vents is
regulated using thumbwheel controls and
adjustable direction vanes.

Air distribution between the windshield,
facia and floor levels is selected
automatically when operating in AUTO
mode but can be selected manually.
