PRINCIPLE OF OPERATION
Introduction
In the event of a collision, the airbag control
unit monitors the rate of deceleration caused
by the collision. This information is then used
to determine whether airbags should be
deployed.
Airbag deployment is de pendent on the rate at
which the passenger compartment changes
velocity following the collision. The
circumstances affecting different collisions
(vehicle speed, angle of impact, type and size
of object hit, etc.), vary considerably and will
affect the rate of de celeration accordingly.
The Supplementary Restraint System (SRS)
components include:-
• SRS warning indicator.
• Rotary coupler.
• Airbag modules.
• Seat belt pre-te nsioners (front seat belts).
• Restraints control module.
• Crash sensors.
• Airbag wiring harnesses. The SRS is not designed to
operate as a result
of:
• Rear impacts.
• Minor front impacts.
• Minor side impacts.
• Heavy braking.
• Driving over bumps and pot holes.
Therefore, it follows that considerable
superficial damage to the vehicle can occur,
without causing the airbags to deploy.

to trigger, or render the system inoperative,
either of which may result in death or serious
injuries.
Do not use any electrical test
equipment or devices in the vicinity of
SRS components or wiring. Doing so

DRIVING AFTER A COLLISION
Before starting or driving
If the vehicle has been involved in an accident
it should be checked thoroughly before
attempting to start the engine or drive the
vehicle.
Check for:-
• Fuel leaks.
• Fluid leaks.
• Battery damage.
• Damage to wiring.
• Damage to lights.
• Damage to steering, suspension, wheels
or tyres.
• Sharp or protruding bodywork.
• Operation of doors and locks.
• Condition and operation of seat belts and
SRS components.
• Activation of the pe destrian protection
system.
• Condition of chil d seats and their
mounting/attach ment points.
Note: This list is not exhaustive.
Resetting the fuel cut-off
The fuel system cut-off forms part of the Safety
and Restraint System (SRS) fitted to your
vehicle. Following an impact, and depending on
the severity, the fuel pump may be switched
off.
1.Switch the ignition off, and wait for 10
seconds.
2. Without pressing the brake pedal, press
the engine START/STOP button, to switch
the electrical circuits on. Wait for 30
seconds.
3. Check the vehicle thoroughly for fuel leaks.
If a leak is detected switch the ignition off
immediately.
•The vehicle must not be started if a leak
is present. Seek qualified advice, and
have the vehicle recovered.
4. If no leaks are detected, start the engine.
WARNING
