DRIVER SUPPORT
Park Assist front, rear and sides*
Park Assist behaves differently depending on
which part of the vehicle is approaching an
obstacle.
Front camera
The warning signal has a continuous tone when the
obstacle is less than approx. 30 cm (1 ft) from the
vehicle.
The Park Assist system's front sensors are
automatically activated when the engine is
started. They are active at speeds
below 10 km/h (6 mph).
The distance monitored extends
approx. 80 cm (2.5 ft) in front of the vehicle.

NOTE
The Park Assist system is deactivated
when the parking brake is used or when P
is selected on vehicles with automatic
transmission.
CAUTION
When installing auxiliary lights: Make sure
these do not obscure the sensors – the
auxiliary lights could be perceived as an
obstacle.
Back
The warning signal has a continuous tone when the
obstacle is less than approx. 30 cm (1 ft) from the
vehicle.
The rear sensors will be activated if the vehicle
begins rolling backward or if reverse gear is
engaged.
The distance monitored extends
approx. 1.5 meters (5 ft) behind the vehicle.
Side sensors
The warning signal will begin pulsating rapidly when
the obstacle is less than approx. 25 cm (0.8 ft) from
the vehicle.
Park Assist's side sensors are automatically
activated when the engine is started. They are
active at speeds below 10 km/h (6 mph).
The distance monitored is approx. 25 cm
(0.8 ft) out from the sides.
The detection area of the side sensors increa-
ses significantly, however, when the steering
angle of the front wheel increases and
depending on the position of the steering
wheel, obstacles up to approx. 90 cm (3 ft)
