Layout and operation
A 4-channel parking aid is available as an option.
If the ignition lock is turned to the position "II" and reverse gear is engaged then the sensors at the rear of the vehicle are activated. A signal is then sounded to indicate readiness for operation.
After activation the system performs a self-test.
In the event of a fault a signal tone sounds for three seconds at a frequency of 1.5 kHz.
The middle sensors can detect obstacles to the rear of the vehicle at a distance of up to 150 cm. The corner sensors both detect obstacles to the side of the vehicle at a distance of up to 60 cm.
Ultrasonic sensors
The parking aid sensor emits an ultrasonic signal and then receives back the reflected sound waves. The time taken by the sound waves to return to the sensor corresponds to the distance to the obstacle. The faster the sound waves are reflected, the closer is the obstacle.
The sensors must be kept free of ice, snow, dirt, scratches and dust deposits to ensure reliable operation of the system.
When cleaning the vehicle with a high-pressure water jet, the sensors must only be sprayed for a short time, and never from a distance below 20 cm.
Never use rough or sharp objects to clean the sensors.
