13.4 TRUNK
13.4.1 Trunk, Description
The trunk houses the spare wheel, the battery, an electrical carrier containing electrical fuses, relays and modules and
a compact disc auto-changer attached to body bracketry. The trunk is fitted with push-fit, velour finish, liners (1 Fig. 1) to the sides and front inner panel; the trunk floor is covered with carpet attached to a removable floor board (2 Fig. 1) and a battery cover (3 Fig. I), one covering the spare wheel and wheel changing equipment, the other covering the
battery and electrical carrier.
The floor board rests on the spare wheel, the front and rear edges
of the floor board locating in blocks on the fuel tank
backboard and on the rear of the body. The blocks accommodate the two possible height settings caused by the differ- ence in thickness between the space saver and full sized spare wheels.
A tread plate (4 Fig. 1) is attached to the trunk sill and a liner is fitted to the rear of the trunk below the sill. Interior trim finisher panels are fitted to the rear lamp units accessed from the trunk opening.
The trunk lid
(5 Fig. 1) is fitted with a removable moulded liner and two trunk illumination lights; the lid is supported by two gas struts, attached through press-on fittings between the inner wheel arch and trunk hinge (6 Fig. 1). A warning
triangle is attached by a bracket to the trunk lid and retained in the open position by a rubber block (Europe inc UK only).
Trunk locking is based on a central latch and striker, operated electrically through the central locking system
by an ad- jacent actuator or by key in a barrel lock located behind the trunk lid badge.
For details on renewal
of trunk front and side liners, trunk carpet, trunk seal retainer and battery cover, see relevant

Fig. 1 Control layout (see key listing below)
The following description of the various control panel functions is provided as a brief over
-view to assist in function
checking. Further information concerning the control panel to component interface may be found in the fault finding
procedures (this section) or the Electronic Diagnostic Manual (EDM).
Iynfe: The system may be activated by any one of four commands. a) AUTO button item 1 1; b) DEFROST button item 12; c) NC button item 10; d) OFF switch item 1.
1. Combined push for OFF and rotary FAN SPEED control. The speed of the two fans is changed by clockwise (to
increase) or anti-clockwise rotation of the knob. Operation of the control, (push) OFF or (rotate) FAN over-rides
the AUTO selection and cancels the 'AUTO' display.
2. RECIRCULATE AIR push-on / push-off button and state lamp, used to prevent outside air being drawn into the
cabin. There are two modes:
a) Press and immediate release; provides timed recirculation of five
(5) minutes. b) Press and hold for two (2) seconds; 'latches' the mode until operator over-ride.
3. Temperature scale SELECTOR for Celsius or Fahrenheit.
4. FANS SPEED display bar graph.
5. TEMPERATURE numeric display for demand and exterior.
6. Selected temperature SCALE temperature numeric display.
7. EXTERIOR temperature option display.

w: In ambient temperatures below Oo C, the system may log fault code 23 because the low ambient causes a tem-
porary low gas pressure. Where the ambient temperature rise above 40" C, and if the engine is close to over- heating, feed to the compressor clutch may be cut and code 23 registered.*

15.1.6 Fire Hazard Infonnath
Thermal decomposition or combustion may produce dense smoke and other dangerous fumes which in fire situations
form
a highly toxic explosive.
In the event of fire the surrounding area must be evacuated and
all personnel kept well upwind of the area.
Full fire fighting protective gear and
a self contained breathing apparatus operating in the positive pressure mode must
be worn for combating fire. Material near fires must be cooled with water spray to prevent ignition.
Fires should be allowed to burn themselves
out if not threatening to life or property. If fire is threatening to life or prop- erty use copious quantities of water to extinguish.
15.1.7 Ventilath
Local exhaust ventilation designed by a professional engineer should be provided if vapours, fumes, or dusts are gen- erated whilst working with airbag module.
The latest issue of the manual for recommended practices on 'Industrial Ventilation' is available from the
ACGIH Com- mittee on Industrial Ventilation, PO Box 16153, Lansing, MI 48910, USA.
The need for local exhaust ventilation should be evaluated by a professional industrial hygienist.
15.1.8 Respiratory Precauth
To prevent the inhalation of dangerous fumes and dusts, an approved mask should be worn.
15.1.9 Eye Protection
Chemical protective goggles are recommended where there is a possibility of eye contact with the propellant.
Safety glasses with side shields are recommended for
all other operations.
15.1. I0 Protective Clothing
Approved protective gloves, overalls and shoes / boots should be worn.
15.1.1 1 Handling and Storage Precautions
Do not store airbag module near live electrical equipment or circuitry. Store in a dry environment at ambient tempera-
tures.
Good housekeeping and engineering practices should be employed to prevent the generation and accumulation of
dusts. Store in compliance with
all local state and federal regulations.
15.1.12 Driver And Passenger Airbag Modules Assembly / Removal / Service Instructions
Before starting work, ensure ignition switch is in 'IocK position, key is removed and negative terminal cable
is disconnected from the battery.
As the airbag is equipped with a back up power source and due to the risk of airbag being inadvertently
deployed, wait one minute or longer before starting work.
0 Disconnecting the battery cancels the memory for clock, radio, seats, mirrors, steering column and any other
components using battery power. Reset memory after work is completed.
0 Never use airbags from other vehicles, always use new parts.
0 After work is completed, reconnect battery and perform warning light check see diagnostic manual.
0 Never use electrical probes to check voltage or electrical resistance.
0 Disconnect the airbag before carrying out any work on, or in the vicinity of module, or when using electric weld- ing equipment.
0 Always ensure that battery negative has been disconnected for one minute or longer before commencing any
removal procedure.
