Manual transmission
The Automatic Parking Assistant calculates
the ideal line for pulling out of the parking
space and takes over the steering during this
maneuver until the driver can drive out of the
parking space without further steering move-
ments without a problem.
Steptronic transmission
The Automatic Parking Assistant calculates an
optimal line for pulling out of a parking space
and takes control of the following functions
during the maneuver:
▷ Steering.
▷ Accelerating and braking.
▷ Changing gears.
The vehicle maneuvers automatically until the
vehicle reaches a position in which the driver
can drive out of the parking space without fur-
ther steering movements.
Safety information
Warning
The system cannot serve as a substitute for
the driver's personal judgment in assessing
the traffic situation. Based on the limits of
the system, it cannot independently react
to all traffic situations. There is a risk of
accident. Adjust driving style to traffic condi-
tions. Check surrounding traffic and vehicle's
surroundings closely and actively intervene
where appropriate.
In addition, the safety information for the Park
Distance Control and the Automatic Parking
