Risk of accident
Parktronic is only an aid and may not detect
all obstacles. It is not a substitute for attentive
driving.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. You could, otherwise, endanger
yourself and others. G
Risk of injury
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured. Parktronic is an electronic parking aid with
ultrasound. It indicates visually and audibly
the distance between your vehicle and an
object.
Parktronic is automatically activated when
you switch on the ignition and release the
handbrake.
Parktronic is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
Parktronic monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper.
:
Example: sensors in the front bumper,
left-hand side
Range of the sensors The sensors must be free of dirt, ice and
slush; otherwise, they may not function cor-
rectly. Clean the sensors regularly, taking
care not to scratch or damage them.

Centre Approximately 100 cm
Corners Approximately 60 cm
Rear sensors
Centre Approximately 120 cm
Corners Approximately 80 cm
!
When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer towbars. Parktronic
does not detect such objects when they are
in the immediate vicinity of the vehicle. You
could damage the vehicle or the objects.
Ultrasonic sources such as an automatic
car wash, a lorry's compressed-air brake
system or a pneumatic drill could cause
Parktronic to malfunction.
Minimum distance Centre Approximately 20 cm
Corners Approximately 15 cm
If there is an obstacle within this range, all
warning displays light up and a tone sounds.
If the distance falls below the minimum clear-
ance, it may no longer be shown.
Warning displays The warning displays show the distance
between the sensors and the obstacle. The
warning display for the front area is located on the dashboard above the centre air vents.
The warning display for the rear area is loca-
ted on the roof lining in the rear compart-
ment.

; Right-hand side of the vehicle
= Indicator segments
The warning display for each side of the vehi-
cle is divided into five yellow and two red seg-
ments. Parktronic is operational if yellow indi-
cator segments =light up.
