Parking and maneuvering


— Park assist plus is an assist system. The driv-
er is still responsible for monitoring the ve-
hicle's surroundings and preventing colli-
sions when using the system.
— When using park assist plus to drive into or
out of a parking space, the steering wheel
turns quickly on its own. Reaching into the
steering wheel spokes while this is happen-
ing can result in injury.
— Sensors and cameras have spots in which
the surrounding area cannot be detected.
Objects, animals, and people may only be
detected with limitations may not be detect-
ed at all. Always monitor the traffic and the
vehicle's surroundings directly and do not
become distracted.

@) Tips
— You can reduce the speed specified by the
system at any time by pressing the brake
pedal.
— The system can incorrectly interpret parking
space barriers (such as parking curbs). Take
over the parking process = page 173 if the
vehicle is not completely inside the parking
space or if the vehicle tries to drive over the
parking space barrier.
— The image in the display is an enlarged and
distorted image. Under certain circumstan-
ces, objects may appear different and un-
clear on the display. This is especially true if
there are objects that do not touch the
ground, such as the bumper of a parked ve-
hicle or the rear of a truck. Drive with spe-
cial care and do not use the image if neces-
sary.
