The operational function of the Park
Assist system can be affected by dirty
sensors, especially at times of snow and
ice.
Make sure that the area on the bumpers
around the sensors is free of dirt, ice and/
or slush, otherwise the Park Assist may not
function properly.
For cleaning the driving systems sensors, see
(Y page 465).
!
High-frequency sources such as toll
stations, speed measuring systems, etc.
can cause the Park Assist system to
malfunction. You can switch off the Park
Assist using the Park Assist button or
switch off the radar sensors with the
instrument cluster control system to
prevent possible malfunction.
The Park Assist is an electronic parking aid
with radar sensors that helps you while
parking. It visually and audibly indicates the
relative distance between the vehicle and an
obstacle.
The Park Assist is automatically activated
when the engine is running and the automatic
transmission is in drive position D, reverse
gear R or neutral position N.
The Park Assist deactivates at speeds over
approximately 10 mph (16 km/h). At lower
speeds the Parktronic system turns on again.
The Park Assist is also switched off when you
set the automatic transmission into park
position P or switch off the engine.
While the automatic transmission is in neutral
position N, the Park Assist is switched off if
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 465).
