you secure the vehicle in place with the
electronic parking brake.
The Park Assist monitors the surroundings of
your vehicle with four sensors in the front
bumper and two sensors in the rear bumper.
Range of the sensors
The sensors of the Park Assist system are
integrated in the front and rear bumpers.
Make sure that the bumpers are clear of dirt,
ice and slush in the area of the sensors, as
otherwise, Park Assist may not function
properly, see (
Y page 486).
Due to the sensors’ broad detection range, it
is possible that the Park Assist also detects
and issues a warning for obstacles in the
ground, e.g. sewer canal covers, rails, bumps
in the road or gutters or obstacles moving
upward quickly, e.g. rolling garage doors.
Front sensors
Center approx. 40 in (100 cm)
Corners approx. 24 in (60 cm)
Rear sensors
Center approx. 50 in (125 cm)
Corners approx. 24 in (60 cm)
! While parking, pay particular attention to
objects over or underneath the sensors,
e.g. flower boxes, an elevated crossbar or
a trailer tow hitch. The Park Assist does not
detect such nearby objects. You could
otherwise damage the vehicle or the
objects.
Warning indicators
Visual signals indicate to the driver the
relative distance between the sensors and an
obstacle.
The warning indicator for the front area is in
the instrument cluster. The warning indicator
for the rear area is on the roof liner in the rear.
1 Left side of the vehicle
2 Right side of the vehicle
3 Readiness indicators
Each warning indicator is divided into five
yellow and two red distance segments for
either side of the vehicle.
