GENERAL INFORMATION
03-21
Supplementary Restraint System (SRS)
Precautions
The following precautions must be adhered to when
working on the SRS system.
WARNING: All components of the SRS must be
replaced every 15 years.
WARNING: Do not use rear facing child seats in
the front passenger seat if the vehicle is fitted
with a passenger airbag.
General Precautions
The SRS contains components which could be
potentially hazardous to service personnel if not
serviced and handled correctly. The following
guidelines are intended to alert personnel to potential
sources of danger and emphasise the importance of
ensuring the integrity of SRS components fitted to
the vehicle.
WARNING: Always follow the 'SRS Precautions'
and the correct procedures for working on SRS
components. Persons working on SRS systems
must be fully trained and have been issued with
copies of the safety guidelines.
WARNING: It is imperative that before any work
is carried out on the SRS system, the appropriate
information is read thoroughly.
WARNING: 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.
WARNING: Always replace a seat belt assembly
that has withstood the strain of a severe vehicle
impact or if the webbing shows signs of fraying.
WARNING: Always disconnect the vehicle
battery before carrying out any electric welding
on a vehicle fitted 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:
l
Steering system - Steering wheel airbag,
rotary coupler
l
Front fascia - Passenger front airbag
l
Interior trim - Head airbag modules - front and
rear
l
Seats - Front seat belt pre-tensioners
l
Electrical system - SRS harnesses, link leads
and connectors
l
Front doors - Side (thorax) air bags
Making the system safe
Before working on or in the vicinity of SRS
components, ensure the system is rendered safe by
performing the following operations.
l
Remove the ignition key
l
Disconnect battery, earth lead first
l
Wait 10 minutes for the SRS power circuit to
discharge before commencing work
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 (10 minutes)
in order to avoid the risk of accidental deployment.
