Cruise control
INTRODUCTION
- NOTE! Read through the whole installation instruction before starting the work.
- The illustrations display the procedure in order of operation. The order of operation is repeated in the text section
Cars equipped with SRS/SIPS (Airbag)
Warning! Extra care must be taken when working on cars equipped with SRS/SIPS airbags. 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 authorised Volvo workshop.
Is the car equipped with SRS (supplemental restraint system)?
Cars equipped with a driver's airbag have the letters "SRS" embossed 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 has SIPS cushions, both front seats have "SIPS" stitched into the upholstery.
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 airbag 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 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.

- Insert a screwdriver in the hole (1) on the reverse of the steering wheel, at right angles to the rear surface of the steering wheel. Insert the screwdriver as far as possible to determine the position of the end of the spring clip (2).
- Position the end of the screwdriver on the top of the spring clip as illustrated
- Pry the screwdriver upwards towards the upper edge of the hole (1) so that the end of the screwdriver presses the spring clip down (2) until one side of the steering wheel module springs out and releases from the mounting.
