Air Distribution


Ou
tside air enters the plen
um via four inlets in the lower windshield panel.
If the air conditioning system is operating in FRESH mode (not recirculation mode), then air is drawn through the four
plenum apertures (and particle filters where fitted) and into the air conditioni ng unit via the blower interconnecting ducts in
the LH and RH blower assemblies. Air is c ooled and dehumidified as it passes through the evaporator and is then 'reheated'
to the required temperature as it passes through the heater matrix.
In RECIRCULATION mode, the air in the pass enger compartment is drawn into the air conditioning unit via the recirculation
air inlets on the blower assemblies.
In FRESH mode, air flows from the cabin into the trunk through a gap between the backlight and the parcel shelf. The air is
exhausted from the vehicle through extraction vent assemblies (incorporating one way flaps) whose outlets are above the
rear mufflers.

-level mode

The CD Autochanger and amplifier are mounte d on a bracket as a single assembly located at the left hand side of the trunk.
The complete assembly must be removed before the CD Autochanger and amplifier can be separated.
When the CD option is selected, the CD unit cycles through a self-check sequence and indicates the current status on the
message display. Refer to the Sound System Ha ndbook for complete operating instructions.

Antenna - Antenna
Description and Operation
The electrically operated antenna operates automatically when the Ignition switch is set to position 1 or 2, and the radio
cassette player is switched on , regardless of the status of the tape or CD mode switch.
The antenna motor is protected by a 10A fuse, F9, located in the trunk fuse-box.

License plate lamps
Each license plate bulb is accessible after removing the relevant lens. The license plate lamps can be accessed following
removal of the trunk lid liner and upper trim finisher.
Rear lamp assembly
Each rear lamp assembly incorporates a stop/tail lamp, a fog lamp, a reversing lamp and a direction indicator lamp. Access
for bulb replacement is from the trunk.
Side markers
Each side marker is retained in the bumper cover by a lug on one end of the unit and a spring clip at the other end. The unit is not electrically connected for all markets.
High mounted stop lamp
The high mounted stop lamp (HMSL) is secu red to studs on the center lower edge of the backlight and provides illumination
using five bulbs.
Operation
All lamps are controlled by the BPM which pr ovides an appropriate output in response to an input received when a selected
switch is operated.
The side marker lamps receive an input from the BPM via relay 3 and fuse F21. The license plate lamps receive an input
from the BPM via relay 3 and fuse F19. The rela y and fuses are located in the trunk fuse-box.
The tail lamps receive an input direct from the BPM.
The stop, reversing and rear fog lamps are controlled by the security and locking module (SLM) which receives inputs via
the SCP network from the BPM.
The HMSL is not controlled by the SLM; it receives input from the brake switch via relay 5 and fuse F8 in the trunk fuse-box.

The BPM and SLM monitor the stop lamps (n ot HMSL) and tail lamps for failure.
Fault analysis must be undertaken using the PDU, refer to Diagnosis and Testing.
Consult the relevant Electrical Guid e for details of circuit operation.

Rear courtesy/ reading lamps
Each rear quarter of the passenger compartment is fitted with combined lighting units comprising; a rear courtesy lamp and
reading lamp. The courtesy lamps operate automatically whenever a rear door is opened; the reading lamps function when
the integral switches are operated by occupants of the vehicle.
Trunk lamps
The trunk trim panel is fitted with lamps which operate auto matically whenever the trunk lid is opened; the switch is
incorporated within the latch mechanism.
Vanity mirror lamps
The vanity mirror lamps, two on each sun visor, operate auto matically when the mirror flap is opened, provided the sun
visor spindle is engage d in the stowage clip.
Operation
The BPM provides an enable signal for the glovebox, vanity mirror, trunk lid and map lamps. Actuation of the relevant
switch provides an earth path to the lamp.
The rear passenger reading lamps receive a supply di rect from fuse F10 in the RH heelboard fuse-box.
The front and rear courtesy lamps have separa te fade functions controlled by the BPM.
The door hazard / puddle lamps are controll ed locally by the relevant Door Module.
Fault analysis must be undertaken using the PDU, refer to Diagnosis and Testing.
Refer to the relevant Electrical Guid e for details of circuit operation.
