Supplementary Restraint System (SRS) Precautions
WARNING: Do not install rear facing child seats in the front passenger seat.
The SRS contains components which are potentially hazardous to service personnel if not handled correctly. The following
guidelines and precautions are intended to alert personnel to potential sources of danger and emphasise the importance of
ensuring the integrity of the SRS components installed to the vehicle.
WARNING: The following precautions MUST be adhered to when working on the SRS system:
The correct procedures must always be used when working on SRS components.
Persons working on the SRS system must be fully trained and have been issued with the safety guidelines.
The airbag modules contain extremely flammable and hazardous compounds. Contact with water, acids or heavy
metals may produce harmful or explosive results. Do not dismantle, incinerate or bring into contact with electricity
before the unit has been deployed.
Always replace a seat belt assembly that has withstood the strain of a severe vehicle impact or if the webbing
shows signs of fraying.
Always disconnect the vehicle battery before carrying out any electric welding on a vehicle installed with an SRS
system.
CAUTION: Do not expose airbag modules or seat belt pre-tensioners to temperatures exceeding 85° C (185° F).
It should be noted that these precautions are not restricted to operations performed when servicing the SRS system. The same
care should be exercised when working on ancillary systems and components located in the vicinity of SRS components; these
include but are not limited to:
Steering wheel airbag, rotary coupler.
Passenger front airbag.
Head airbag modules - front and rear.
Seat belt pre-tensioners.
SRS harnesses, link leads and connectors.
Side (thorax) air bags.
Making the system safe
Before working on or in the vicinity of SRS components, make sure the system is rendered safe by performing the following
operations:
Remove the ignition key.
Disconnect battery, earth lead first.
Wait 2 minutes for the SRS power circuit to discharge before commencing work.
NOTE: The SRS uses energy reserve capacitors to keep the system active in the event of electrical supply failure under
crash conditions. It is necessary to allow the capacitors sufficient time to discharge (2 minutes) in order to avoid the risk of
accidental deployment.
Installation
In order to make sure system integrity, it is essential that the SRS system is regularly checked and maintained so that it is
ready for effective operation in the event of a collision. Carefully inspect SRS components before installation. Do not install a
part that shows signs of being dropped or improperly handled, such as dents, cracks or deformation.
WARNING: The integrity of the SRS systems is critical for safety reasons. Make sure the following precautions are always
adhered to:
Do not install accessories or other objects to trim panels which cover ITS airbags.
Never install used SRS components from another vehicle or attempt to repair an SRS component.
When repairing an SRS system, only use genuine new parts.
Never apply electrical power to an SRS component unless instructed to do so as part of an approved test
procedure.
Special fixings are necessary for installing an airbag module – do not use other fixings and make sure that all
fixings are tightened to the correct torque.
Always use new fixings when replacing an SRS component.
CAUTIONS:
Take care not to trap airbag modules when installing interior trim components.
Make sure SRS components are not contaminated by oil or grease.
NOTES:
Following seat belt pre-tensioner deployment, the seat belts can still be used as conventional seat belts but will need to

General Information - Road/Roller Testing
Description and Operation Published: 11-May-2011
Road or roller testing may be carried out for various reasons and a procedure detailing pre-test checks, through engine starting
and stopping, pre-driving checks, on-test checks to final checks on completion of the test is given in this section.
Unless complete vehicle performance is being checked, the full road test procedure need not be carried out. Instead, those
items particularly relevant to the system/s being checked can be extracted.
Pre - Test Checks
WARNING: If the brake system hydraulic fluid level is low, pedal travel is excessive or a hydraulic leak is found, do not
attempt to road test the vehicle until the reason for the low fluid level, excessive pedal travel or hydraulic leak is found and
rectified.
It is suggested that pre-test checks, and functional tests of those systems/circuits which affect the safe and legal operations
of the vehicle, such as brakes, lights and steering, should always be carried out before the road or roller test.
Engine oil level
Engine coolant level
Tires, for correct pressure, compatible types and tread patterns, and wear within limits
There is sufficient fuel in the tank to complete the test
All around the engine, transmission and under the vehicle for oil, coolant, hydraulic and fuel leaks. Make a note of any
apparent leaks and wipe off the surrounding areas to make it easier to identify the extent of the leak on completion of
the test
Starting the Engine
CAUTION: On initial drive away from cold and within the first 1.5 km (1 mile), do not depress accelerator pedal beyond
half travel until the vehicle has attained a minimum speed of 25 km/h (15 miles/h). Never operate at high engine speed or
with the accelerator pedal at full travel whilst the engine is cold.
With the ignition switched off, check:
The parking brake is applied
The transmission selector lever is in Park
All instrument gauges (except fuel gauge) read zero
With the ignition switched on, check:
Ignition controlled warning lamps come on
Engine coolant temperature gauge registers a reading compatible with the engine coolant temperature
Fuel gauge registers a reading appropriate to the fuel level in the tank
The operation of the parking brake and brake fluid level warning lamps
On Road or Roller Test Check:
CAUTION: If road testing, check the brake operation while still travelling at low speed before continuing with the test. If
the brakes pull to one side, or appear to be otherwise faulty, do not continue with the road test until the fault has been found
and rectified.
Initial gear engagement is smooth
Parking brake control operates smoothly and the parking brake releases quickly and completely
Transmission takes up the drive smoothly, without judder
The engine power output is satisfactory, full power is achieved, acceleration is smooth and pedal operation not stiff or
heavy, and engine speed returns to idle correctly
There is no excessive or abnormally colored smoke from the engine under normal driving, heavy load or overrun
conditions
Steering operation, including power steering, is smooth, accurate, not excessively heavy or with excessive free play or
vibration. Does not pull to one side and self centres smoothly after cornering
Speedometer, oil pressure warning lamp, coolant temperature gauge and tachometer register the correct readings or
operate correctly
Switches and controls operate smoothly and positively, warning lamps operate correctly and the direction indicator
control self cancels when the steering is returned to the straight ahead position
Heating and ventilation systems work correctly and effectively
Brake operation and efficiency
Brake Testing
WARNING: When brake testing, avoid breathing the smoke or fumes from hot brakes, this may contain asbestos dust
which is hazardous to health, see Health and Safety Precautions.
