one of the doors is open, or there is a fault in
the circuit. After the initial 10 second period,
the LED will flash to indicate that the alarm is
switched on. On unlocking the driver's door
lock, the LED will illuminate for approximately
1 second, then go out, indicating that the
alarm has been switched off.
3 With the alarm set, if the tailgate is
unlocked, the tailgate switch sensing will
automatically be switched off, but the door
and bonnet switches will still be active. Once
the tailgate is shut and locked again, the
tailgate switch sensing will be switched back
on after approximately
10
seconds.
4 Should the alarm system develop a fault,
the vehicle should be taken to a Vauxhall/Opel
dealer for examination.
On models with heated seats, a heater
mat is fitted to both the seat back and seat
cushion. Renewal of either heater mat involves
peeling back the upholstery, removing the old
mat, sticking the new mat in position and then
refitting the upholstery. Note that upholstery
removal and refitting requires considerable
skill and experience if it is to be carried out
successfully, and is therefore best entrusted to
your Vauxhall/Opel dealer. In practice, it will be
very difficult for the home mechanic to carry
out the job without ruining the upholstery.

General information
A driver's airbag is fitted as standard
equipment on all models. The airbag is fitted
in the steering wheel centre pad. Additionally,
a passenger's airbag located in the facia, side
airbags located in the front seats, and curtain
airbags located in the headlining are optionally
available.
The system is armed only when the ignition
is switched on, however, a reserve power
source maintains a power supply to the system
in the event of a break in the main electrical
supply. The steering wheel and facia airbags
are activated by a 'g' sensor (deceleration
sensor), and controlled by an electronic
control unit located under the centre console.
The side airbags and curtain airbags are
activated by severe side impact and operate
independently of the main system. A separate
electrical supply, control unit and sensor is
provided for the side/curtain airbags on each
side of the car.
The airbags are inflated by a gas generator,
which forces the bag out from its location in
the steering wheel, facia, seat back frame, or
headlining.

must be observed when working
on vehicles equipped with an
airbag system, to prevent the possibility of
personal injury.
General precautions
The following precautions must be observed
when carrying out work on a vehicle equipped
with an airbag:
a) Do not disconnect the battery with the
engine running.
b) Before carrying out any work in the
vicinity of the airbag, removal of any of the
airbag components, or any welding work
on the vehicle, de-activate the system as
described in the following sub-Section.
c) Do not attempt to test any of the airbag
system circuits using test meters or any
other test equipment.
d) If the airbag warning light comes on,
or any fault in the system is suspected,
consult a Vauxhall/Opel dealer without
delay. Do not attempt to carry out fault
diagnosis, or any dismantling of the
components.
Precautions when handling an airbag
a) Transport the airbag by itself, bag upward.
b) Do not put your arms around the airbag.
c) Carry the airbag close to the body, bag
outward.
d) Do not drop the airbag or expose it to
impacts.
e) Do not attempt to dismantle the airbag unit.
f) Do not connect any form of electrical
equipment to any part of the airbag
circuit.
Precautions when storing an airbag
a) Store the unit in a cupboard with the
airbag upward.
b) Do not expose the airbag to temperatures
above 80°C.
c) Do not expose the airbag to flames.
d) Do not attempt to dispose of the airbag -
consult a Vauxhall!Ope/ dealer.
e) Never refit an airbag which is known to be
faulty or damaged.
De-activation of airbag system
The system must be de-activated
before carrying out any work on the airbag
components or surrounding area:
a) Switch on the ignition and check the
operation of the airbag warning light on
the instrument panel. The light should
illuminate when the ignition is switched
on, then extinguish.
b) Switch off the ignition.
c) Remove the ignition key.
d) Switch off all electrical equipment.
e) Disconnect the battery negative terminal
(refer to 'Disconnecting the battery' in the
Reference Chapter).
f) Insulate the battery negative terminal and
the end of the battery negative lead to
prevent any possibility of contact.

Activation of airbag system
To activate the system on completion of any
work, proceed as follows:
a) Ensure that there are no occupants in
the vehicle, and that there are no loose
objects around the vicinity of the steering
wheel. Close the vehicle doors and
windows.
b) Ensure that the ignition is switched off
then reconnect the battery negative
terminal.
c) Open the driver's door and switch on the
ignition, without reaching in front of the
steering wheel. Check that the airbag
warning light illuminates briefly then
extinguishes.
d) Switch off the ignition.
e) If the airbag warning light does not
operate as described in paragraph c),
consult a Vauxha/1/0pel dealer before
driving the vehicle.

Warning: Refer to the precautions
given in Section 22 before
attempting to carry out work on
any of the airbag components.
De-activate the airbag system as described
in the previous Section, then proceed as
described under the relevant heading.

2 Turn the steering wheel through 90° so that
the two holes at the rear of the steering wheel
spokes are accessible. Insert a screwdriver
into the holes, one at a time, to depress the
internal spring retainers, and at the same time
pull the airbag unit away from the steering
wheel to release it (see illustrations}.
3 Release the locking clips, then disconnect
the wiring connectors at the rear of the airbag
unit (see illustration}. Remove the airbag unit.
Note that the airbag must not be knocked or
