Collision Avoidance and Parking Assist Systems: Service and Repair
Reverse warning system
Cars equipped with SRS/SIPS (Airbag)
Warning! Extra care must be taken when working on cars equipped with SRS/SIPS air bags. This is important to prevent:1. Personal injury2. Damage to or malfunction of the SRS/SIPS system.Work on the SRS/SIPS systems or related components must be carried out by an authorized Volvo workshop.
Is the car equipped with SRS/SIPS?
Cars with SRS are most easily recognized by the letters SRS on the steering wheel pad. If the car also has an airbag on the passenger side, the letters SRS are embossed on the dashboard above the glove compartment. SIPS decals are located on the seat panels and the windscreen.
Do not damage the SRS wiring!
Do not trap, fray, pierce or damage the SRS wiring. SRS wiring has orange casing and/or is plaited.
Steering and front suspension
The contact reel in the SRS system can easily be damaged when working on the steering wheel, steering shaft or steering gear. Refer to the SRS information on carrying out such work. This is to prevent damage.
SRS warning lamp
If the SRS warning lamp lights after repairs have been carried out, take the car to an authorized Volvo workshop.

WARNING!
The ignition must be in position "0" and the key removed from the ignition if any connector in the SRS system is to be disassembled. Then wait at least five minutes. Then disconnect the battery negative lead before disassembling any of the connectors.
