Chapter
.
Before handling pyrotechnic components (e.g. plugging in the electrical connector) the mechanic must discharge any static electricity. This can be done by briefly touching the door striker plate, or similar.
Install in reverse order of removal; note the following:
Note
Make sure electrical connectors are fitted correctly (as far as stop) and engage audibly.
Make sure that wiring is not trapped.
WARNING
The battery must be connected with the ignition switched on. If pyrotechnic components (e.g. airbag or belt tensioner) are inexpertly repaired, this may result in unwanted triggering after connecting the battery. There must not be anyone in the vehicle while you are connecting the battery.
DANGER!
When working on a vehicle with the ignition switched on or while the drive system is active, the engine can start unexpectedly and exhaust fumes can cause a health hazard in closed rooms. Moving parts can trap or draw in parts of the body and/or clothing (safety hazard).
Before switching on the ignition, perform the following steps:
Move selector lever to position P
Activate parking brake
Switch off ignition.
Open bonnet
Connect battery charger (e.g.
VAS 5095A
) to jump-start connections of 12 V electrical system.
