sound waves.
X See if PARKTRONIC functions in adifferent location. Active Parking Assist
General notes Active Parking Assist is an electronic parking aid
with ultrasound. It measures the road on both
sides of the vehicle. Aparking symbol indicates
as uitable parking space. Active steering inter-
vention and brake application can assist you
during parking and when exiting aparking
space. You may also use PARKTRONIC
(Y page 197).
Important safety notes Active Parking Assist is only an aid. It is not a
substitute for your attention to the immediate
surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that no persons, animals or objects
are in the manoeuvring range.
When PARKTRONIC is deactivated, Active Park-
ing Assist is also unavailable.
For vehicles with the trailer tow hitch folded out,
the minimum length for parking spaces is
slightly longer.
If you have attached atrailer to your vehicle, you
should not use Active Parking Assist. Once the
electrical connection is established between your vehicle and the trailer, Active Parking
Assist is no longer available. PARKTRONIC is
deactivated for the rear area. G
WARNING
While parking or pulling out of aparking
space, the vehicle swings out and can drive
onto areas of the oncomingl ane. This could
cause you to collide with other road users.
There is arisk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
! If unavoidable, you should drive over obsta-
cles such as kerbs slowly and not at asharp
angle. Otherwise, you may damage the
wheels or tyres.
Active Parking Assist may also display spaces
not suitable for parking, e.g.: R parking or stopping restrictions
R in front of driveways or entrances and exits
R unsuitable surfaces Driving systems
