Supplementary restraint system precautions

SUPPLEMENTARY RESTRAINT SYSTEM PRECAUTIONS

General

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.

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 undertaken on the SRS system the appropriate information is read thoroughly.

WARNING: Some 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, 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 electrical welding on a vehicle fitted with an SRS system.

CAUTION: Do not expose an airbag module or seat belt pre-tensioner to heat 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 system - steering wheel airbag, rotary coupler
• Front fascia - passenger front airbag (where fitted)
• Centre console - SRS DCU and SRS harnesses.
• Electrical system - SRS harnesses, link leads and connectors

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.
