event that does not. The RCM governs the operation of the
whole system and performs continual system diagnostics.
Information on the severity of an impact is received from the
impact sensors.
Variations in the deployment of the front airbag modules are
dependent on the status of the front safety belt buckles.
Dual Inflation Technology
When activated, the airbags will deploy at either a normal or
reduced level of inflation, depending on crash severity.
Various sensors determine the direction and severity of an
impact. The system analyses this information then deploys
the appropriate airbags.
Impact Sensors
Side Impact - Side impact sensors are mounted to the base
of each B-pillar and within each door. In the event of a side
impact, the RCM processes the impact data sent by the side
impact sensor against stored data. The RCM will deploy the
side airbag on the side the deployment request was initiated
and the seat belt pretensioner.
Front Impact - Front impact sensors (x2) are located under
the grill opening panel.
The SRS module processes the impact data sent by the front
impact sensor against stored data, and deploys the front
airbags, and the seat belt pretensioners.
Passenger Airbag Deactivation
The passenger airbag can be deactivated using the PAD
(Passenger Airbag Deactivation) switch. Switching the
passenger airbag off allows children under the age of 12 to
be carried safely in the passenger seat. The PAD switch is
located at the passenger end of the instrument panel and is
accessible when the pa ssenger door is open.
Maintenance
Driver’s Airbag Module - Renew
Removal
1. Disconnect vehicle battery.
2. Allow a two minute power down period to de-activate
airbag system.
3. Rotate steering wheel to access and remove bolts (x2) from driver's airbag module to steering wheel (see
Figure 1).
4. Release driver's airbag mo dule, disconnect multiplugs
(x2) and remove airbag module (see Figure 2).
Installation
1. Position driver's airbag mo dule and connect multiplugs
(x2).
2. Install bolts (x2) and tighten.
3. Connect vehicle battery.
LH Front Seat Belt - Renew
Removal
1. Remove front seat (see Workshop Manual procedure 01.10.AB Seat Assembly - Front - LH - Remove for
Access and Refit).
Note
Please see the Owner’s Guid e for the full deactivation
procedure.
Warning
Unnecessary deactivation of the passenger airbag is
dangerous. The passenger will not receive the added
protection from the airbag and serious injuries or even
death could occur. With the exception of installing a child seat on the passenge r seat, do not turn the
passenger airbag deactiva tion switch to the off
position.
Warning
Never place a child in a child seat or on a booster
cushion in the passenger seat if the airbag is active.

Description
Suspension Arms
The upper suspension arm is attached to the body structure.
The lower suspension arm is attached to the front subframe.
Each upper suspension arm has a press-fit ball-joint, and two
interleaved rubber bushes. Two bolts attach the upper
suspension arm to the body structure.
Each lower suspension arm has a press fit ball-joint and
metal-to-rubber bonded bushes which are attached to the
front subframe by two eccentric cam bolts (Camber and
castor settings).
Anti-roll Bar
The anti-roll bar, is attached to the subframe in two positions
by rubber bushes and clamps. The outer ends of the anti-roll
bar are attached to the lower suspension arms by drop links.
The anti-roll bar provides the required stiffness to control
body roll.
Vertical link
The Vertical link (Knuckle Joint) swivels on the upper and
lower suspension arms via ball-joints, and carries the hub, a
unit 3 wheel bearing (including the ABS encoder ring), the
wheel speed sensor, the brake caliper, and the brake disc
and shield. The position of the Vertical link is determined by
the movement of the steering rack, which is connected to
the Vertical link by the steering track rod.
