The suction hose and liquid line are a one-piece
assembly. A single screw connects them to the air
conditioning unit manifold at the bulkhead. A
further screw fixing and push-in clip secures them
at the side of the engine bay. The liquid line fixed
to the cooling module then joins with a block
fitting and the suction hose connects with a quick
connect fitting and routes across the underneath
of the cooling module to the compressor. The
compressor suction and discharge hoses are also a
one piece assembly.
A pressure transducer is fitted to the discharge
hose as it connects to the rear of the condenser.
The high side charge port is situated on the
manifold connecting to the receiver drier whilst
the low side is adjacent to the compressor behind
the LH front wheel.
The compressor is a 9Occ scroll, which is variable
from 100% to 30%. Compressor is standard
specification to all vehicles although package
makes them unique to V6 and V8.
Air Distribution
Air distribution is as follows:
¥ Defrost duct integral with the fascia.
¥ Face vents, plenum, manifold, centre face
duct, side face duct, side window demist duct
are all sub-assembled into the fascia.
¥ Driver and front seat passenger foot ducts are
installed in the fascia after it has been fitted
to the vehicle.
¥ Rear foot ducts are fitted to the underframe.
¥ Rear face duct fitted to transmission tunnel.
¥ Rear face vent fitted to console.
¥ Extractor boxes fitted in rear quarter panels.
All flaps are electric servo controlled and
comprise:
¥ Fresh/recirculation - heater/evaporator unit.
¥ Cold air bypass - heater/evaporator unit.
¥ Foot flap - mounted on plenum.
¥ Defrost flap - mounted on plenum.
¥ Face flap - mounted on plenum.
Sensors, for operation of the system, are:
¥ Ambient temperature sensor - located behind
the lower front grille.
¥ Solar sensor - fitted to the top centre of the
fascia at the defrost grille
¥ In-car sensor - aspirated from the plenum
venturi sensor mounted inboard of the
steering column.¥ Two heater air outlet sensors
¥ One evaporator air outlet sensor
Servicing
Routine servicing consists of particle filter
replacement.
Replaceable items on the climate control system
are:
¥ Servo complete with linkages
¥ Sensors
¥ Evaporator and seals
¥ Heater core and seals
¥ Blower motor
¥ Impeller/blower motor wheel
¥ Hoses
¥ Registers/vents
¥ Ducts, except the defrost
¥ Defrost and side window demist grilles
¥ Control unit
¥ Compressor
¥ Water pump
¥ Water valve
¥ Receiver/drier
¥ Condenser
There are no panel diagnostics but PDU facility is
available with extensive capability, similar to
current XJ and XK Series.
System refrigerant is R134a. Vehicle charge weight
is 800 gms and charging is through the high side
charge port only.
Oil type is WSH-MIC231-B and refill quantity is
180 cc -220 cc.
Special tools are hose clamp pliers and air-
conditioning hoses spring lock de-coupler.
General information
Ensure that the grille at the base of the windshield
is kept clear of leaves, snow or other obstructions.
A solar sensor is mounted on top of the fascia, in
the centre of the defrost grille, and this should not
be covered.
The air conditioning system should be run briefly
at least once each week with a cold setting to
prevent the seals from drying out with subsequent
refrigerant leaks.
When the engine and vehicle interior are cold the
fan speed may be low until the engine has warmed
up, this avoids excessively cold air being blown
into the cabin.

68Heated wiper park or (where optionally fitted)
heated front screen.
With the engine running, due to the high current
draw, press to switch on the heated wiper park to
defrost the wiper park area, or where fitted, press
to switch on the heated front screen for rapid
defrost/demist.
Heated wiper park automatically operates in cold
weather, and may stay on continuously. It is
automatically switched on when ÔDEFROSTÕ is
selected. If manually selected, the heated wiper
park will automatically switch off after 10
minutes.
Heated front screen is automatically switched on
when ÔDEFROSTÕ is selected. It will automatically
switch off after 4 minutes. The heaters will switch
off, or not operate, if low battery voltage is
detected.
Heated Rear Screen
With the engine running due to the high current
draw, press to switch on the heated rear screen
for rapid defrost/demist. The rear screen heater
will be automatically switched off after 10
minutes.
In cold conditions, the heated rear screen
operates automatically. Selecting ÔDEFROSTÕ will
also turn the heated rear screen ON. The heaters
will switch off, or not operate, if low battery
voltage is detected.
Air Distribution
Air distribution is automatically controlled when
ÔAUTOÕ is selected. Manual control can be
achieved using the air distribution buttons.
Heat at Rest Feature (V8 engine vehicles
only)
Interior heating may be continued after the
engine has been switched off by turning the
ignition to position ÔIIÕ. The climate control system
will continue to provide heat to the vehicle
interior until the engine cools down. Excessive use
will cause a low battery voltage, which may
prevent the vehicle from being started.
Voice Activated Control
Some functions of the climate control system can
be operated with the Voice Activation System
(when fitted).
A full operating description is given in the Voice
Activation Handbook included with the vehicle
literature pack.

The VECM is connected to the SCP
communication network. The module allows a
user to request emergency assistance (police,
ambulance, fire, wrecker) or directions to a
desired location at the touch of a button. Also, if
any of the vehicleÕs airbags are deployed while the
VEMS system is powered ON, the system
automatically issues a call for emergency
assistance.

Front Seat Heater Switches
The driver and front passenger have a heater. The
seat heater switches (when fitted) are located on
the center console directly below the climate
control unit. The heaters are in the seat squab
and the seat cushion. The heater will
automatically switch OFF after it has been on for
10 minutes. The heater will maintain a pre-set
temperature while it is switched on. Storage of
the vehicle in a heated garage, body heat, or
warm ambient temperatures may prevent
operation of the seat heater.

Voice Activation
JOL.275
General
Voice Activation, currently available in a limited
number of markets, provides a convenient way of
controlling the following vehicle systems (where
fitted):
¥ Sound System (radio, cassette tape player and
CD player)
¥ In-car Telephone
¥ Climate Control System.
The system is controlled by the Voice button on
the left-hand side of the steering wheel. Voice
commands are picked up by a directional
microphone mounted on the headlining between
the overhead console and the sunvisor. The
microphone is also used for the in-car telephone.
When giving a command, audible feedback will be
heard through the sound system speakers and
messages will be shown on the message center
display. Audible feedback can be turned off if
required. The system is capable of storing unique
nametags for 20 radio stations and 40 phone
numbers. Verbal playback of nametag directories
is provided by issuing the proper voice command
(RADIO DIRECTORY or PHONE DIRECTORY).Personal directories of nametags for phone dialing
and radio station presets can be created and
spoken command help is provided.
Language and Accent
Commands are given in English in a natural
speaking voice, without having to pause between
words. Most United kingdom accents (for vehicles
equipped with a UK Voice Module) or North
American accents (for vehicles equipped with a US
Voice Module) are understood without difficulty
but the system also provides for voice training, if
required. Voice feedback is given in UK English
(for vehicles equipped with a UK Voice Module) or
US English (for vehicles equipped with a US Voice
Module).
Voice Commands
Voice commands are generally in the form of:
¥ System, e.g. Radio
¥ Function, e.g. Tune
¥ Action Required, e.g. 99.7 (to select the
frequency).
Note:
1. Voice commands cannot be given while a
phone call is in progress.
2. While a voice command is being processed,
the command can be canceled by pressing the
Voice button again.
3. Audible feedback can be interrupted by
pressing the Voice button during the verbal
playback. In this case the command is not
canceled.
Command Help
There are commands available which give
spoken/visual help for the voice commands. This
provides a useful reminder of the commands
available while driving.
The commands are:
VOICE HELP; RADIO HELP; TAPE HELP; CD HELP;
PHONE HELP AND CLIMATE CONTROL HELP.
