GENERAL PRECAUTIONS
The SRS system contains components which could
be potentially hazardous to the service engineer if not
serviced and handled correctly. The following
guidelines are intended to alert the service engineer to
potential sources of danger and emphasise the
importance of ensuring the integrity of SRS
components fitted to the vehicle.
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 the SRS components; these
include but are not limited to:
•
Steering system - (steering wheel airbag)
•
Body and trim components - (passenger airbag,
seatbelt pre-tensioners and SRS DCU).
•
Seats - (side airbags)
•
Electrical system components - (SRS harnesses
etc.)
WARNING: Do not use rear facing child
seats in the front passenger seat when a
vehicle is fitted with a front passenger
airbag.
WARNING: Always follow the Safety
Guidelines and correct procedures for
working on SRS components.
WARNING: The front airbag modules
contain Sodium Azide which is poisonous
and extremely flammable. Contact with
water, acid or heavy metals may produce harmful
or explosive compounds. Do not dismantle,
incinerate or bring into contact with electricity.
CAUTION: Do not expose an airbag
module or seatbelt pre-tensioner to heat
exceeding 85
°
C (185
°
F).
NOTE: Front airbag modules should be
replaced every ten years; side airbag
modules should be replaced every fifteen
years.
Making the system safe
Before working on, or in the vicinity of SRS
components, ensure the system is rendered safe by
performing the following procedures:
•
Remove the ignition key from the ignition
switch.
•
Disconnect both battery leads, earth lead
first.
•
Wait 10 minutes for the SRS DCU back-up
power circuit to discharge.
The SRS system 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 capacitor sufficient time to discharge (10
minutes) in order to avoid the risk of accidental
deployment.
WARNING: Always remove the ignition key
from the ignition switch, disconnect the
vehicle battery and wait 10 minutes before
commencing work on the SRS system.
