Parking assistance front and rear
Park Assist System (PAS1) has different behaviour depending on which part of the car is approaching an obstacle.

The Parking Assistance System's front detectors are activated automatically when the engine is started. They are active at speeds below 10 km/h (6 mph).
The measuring range is approx. 80 cm (2.5 ft) in front of the car.
Note
Parking assistance is deactivated when the parking brake is used or P mode is selected in a car with an automatic gearbox.
Important
When auxiliary lamps are fitted: Remember that these must not obscure the sensors - the auxiliary lamps may then be perceived as an obstacle.

The sensors for reverse are activated if the car rolls backward without a gear engaged or when the gear lever is moved to reverse position.
The measuring range is approx. 1.5 metres (5 ft) behind the car.
