The radio's/stereo's sound level is muted and a pulsating "buzzer tone" starts to sound in the car's rear speakers when approx. 150 cm (4.9 feet) remain to the obstruction and becomes a constant tone when the obstruction is approx. 30 cm (12 in) from the rear bumper. The kit consists of four sensors that are almost hidden in the rear bumper, a control module and a buzzer with adjustable volume. Sensors and holder painted in the color of the car. The system can be shut-off when reversing with a caravan for example.

The kit consists of four sensors that are installed in the rear bumper, a control module, as well as wiring. Holders and sensors are painted in the same color as the car. It is possible to turn the system off manually via the menu in the radio display. If Volvo genuine towbar cables are used, it is turned off automatically by the system when you are reversing with a trailer.

S40, V50,-05-07 30786 669 + Application1 S40, V50 30660 684 + Activator2 S40, V50 8637 076 + Hole punching tool3 S40, V50 9997 114 The system is activated when speed is less than 15 km/h (10 mph). A signal indicates the distance to objects in front of the car. When an object is indicated, the volume of the radio/stereo is lowered and a pulsating "buzzer tone" is heard from the car's front speakers. The tone starts when the obstruction is about 80 cm (30 in) away and increases to a continuous tone when the obstruction is approx. 30 cm (12 in) away from the front bumper. In order to differentiate between the front and rear systems, different tone frequencies are used and the sound comes from different speakers, front or rear. The kit consists of wiring and four sensors that are installed almost invisibly in the front bumper. The sensors are painted the same color as the car's bumper. This system can produce "false" signals as a reaction to external sound sources with the same frequency as the system's sensors. Typical sources are the horn, wet tires on asphalt, pneumatic brakes and motorcycle exhaust pipes. The system can be turned off manually via the radio menu.
