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 always be carried out by an authorized Volvo workshop.
Is the car equipped with SRS (supplemental restraint system)?
Cars equipped with a driver's airbag have the letters "SRS" imprinted on the centre panel of the steering wheel. Cars equipped with driver's and passenger airbags are marked with "SRS" on both the steering wheel centre panel and also on the dashboard close to the airbag.
If the car is equipped with SIPS (side impact protection system ) a "SIPS" decal is marked on both the front seats.
Cars equipped with inflatable curtains have the marking "SRS" on one of the panels along the posts on the inside of the car.
Cars equipped with SRS (supplemental restraint system) also have an "SRS" decal on the front windscreen.
Warning! The air bag inflation areas must not be obstructed. Never place any objects, such as upholstery or accessories, within these areas. The panels must be able to open in the correct manner at the right time, otherwise there is an increased risk of personal injury in the event of a collision.
Do not damage the SRS wiring!
Do not trap, chafe, 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 (supplemental restraint system) for 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.
