Important safety notes PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It monitors the area around
your vehicle using six sensors in the front
bumper and six sensors in the rear bumper.
PARKTRONIC indicates visually and audibly the
distance between your vehicle and an object.
PARKTRONIC is only an aid. It is not a substitute for your attention to the immediate surround-
ings. The responsibility for safe manoeuvring
and parking remains with you. Make sure that
there are no persons, animals or objects in
range while manoeuvring and parking.
! When parking, pay particular attention to
objects above or below the sensors, such as
flower pots or trailer drawbars. PARKTRONIC does not detect such objects when they are in
the immediate vicinity of the vehicle. You
could damage the vehicle or the objects.
The sensors may not detect snow and objects which absorb ultrasonic sources.
Ultrasonic sources, such as an automatic car
wash, a lorry's compressed-air brakes or a
pneumatic drill, could cause PARKTRONIC to
malfunction.
PARKTRONIC may not function correctly on
uneven terrain. Driving systems
