the vehicle out of snow or slush), you
can shift back and forth between
drive position
D and reverse gear

Warning
G
Parktronic is only an aid and may not de-
tect all obstacles. This system does not
relieve you of the need to pay attention.
You are always responsible for safety and
must continue to pay attention to your im-
mediate surroundings when parking and
maneuvering. Otherwise, you could en-
danger yourself and others.
Warning
G
Make sure that no persons or animals are
in the maneuvering range of the vehicle.
They could otherwise be injured.

Parktronic is an electronic parking aid
and informs you visually and audibly of
the distance between the vehicle and an
obstacle.
Parktronic is automatically switched on
when you switch on the ignition and re-
lease the handbrake. You must also
move the selector lever to position
D, N
or R.
Parktronic switches off at speeds of over
11 mph (18 km/h). It switches on again
as soon as the vehicle’s speed falls be-
low this limit speed.
Parktronic is equipped with sensors in
the front and rear bumper to monitor the
area around your vehicle.
Range of the sensorsThe sensors must be free from dirt, ice
and slush, otherwise they may not func-
tion correctly. Clean the sensors regu-
larly, taking care not to scratch or
damage them (
\2
page 422).
