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 injury
2. 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 authorised 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 a
"SRS" decal on the front 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 (supplemental restraint system) Service Manual or service
instructions in VIDA 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 authorised Volvo workshop.

in the centre console, in front of the parking brake.
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 deploy in the correct manner
at the right time otherwise there is a risk of personal injury in
the event of a collision.
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 one minute. Then disconnect
the battery negative lead before disassembling any of the
connectors. When work is completed the ignition key must be
turned to position "II" before reconnecting the battery negative
lead.
