chains if necessary.

When testing the parking brake, operate
the vehicle only briefly (for a maximum of
ten seconds) on a brake dynamometer.
When doing this, turn the key to position
0 or 1 in the ignition. Failure to do this can
cause damage to the drive train or the
brake system.
!
A function or performance test should
only be carried out on a twin-axle dyna-
mometer. If you wish to operate the vehicle
on such a dynamometer, please consult a
Mercedes-Benz Service Centre in advance.
You could otherwise damage the drive train
or the brake system.
Parktronic*
G
Risk of accident
Parktronic is only an aid and may not detect
all obstacles. It is not a substitute for atten-
tive driving.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
manoeuvring. You could otherwise endan-
ger 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. It indi-
cates visually and audibly the distance
between your vehicle and an object.
Parktronic is activated automatically when
you:
R
switch on the ignition
R
release the parking brake
R
shift the automatic transmission to D, R or
N
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
