The function of the electric parking brake is
dependent on the on-board voltage. If the on-
board voltage is low or if there is a malfunc-
tion in the system, it may not be possible to
apply the released parking brake.
X If this is the case, only park the vehicle on
level ground and secure it to prevent it from
rolling away.
X Vehicles with automatic transmission:
shift the automatic transmission to posi-
tion P.
X Vehicles with manual transmission:
engage first gear.
It may not be possible to release an applied
parking brake if the on-board voltage is low or
if there is a malfunction in the system. Con-
tact a qualified specialist workshop.

General notes The electronically controlled damping system
works continuously. This improves driving
safety and ride comfort.
The damping is tuned individually to each
wheel and depends on:
R your driving style, e.g. sporty
R the road surface condition, e.g. bumps
R your individual selection of "Sport" or
"Comfort"
The suspension setting is adjusted using the
corresponding button in the centre console.
i The mode can also be set using the AMG
DYNAMIC SELECT controller (Y page 175).
If the ignition is switched off for less than four
hours, the previously selected drive program
is activated when the engine is next started. If the ignition is switched off for more than fourhours, Comfort mode is activated when the
engine is next started. Sport mode The firmer setting of the suspension tuning in
Sport mode ensures even better contact with the road. Select this mode when employing a
sporty driving style, e.g. on winding country
roads.

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.
! Fold in the ball coupling if the trailer tow
hitch is not required. PARKTRONIC meas-
ures the minimum detection range to an
obstacle from the bumper, not the ball cou- pling.
PARKTRONIC is activated automatically when you:
R switch on the ignition
R shift to position D,Ror Non vehicles with
automatic transmission
R release the electric parking brake
PARKTRONIC is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
PARKTRONIC is deactivated for the rear area when you establish an electrical connection
between your vehicle and a trailer.
Range of the sensors General notes
PARKTRONIC does not take into account
obstacles located:
R below the detection range, e.g. persons,
animals or objects
R above the detection range, e.g. overhang-
ing loads, tail sections or loading ramps of
goods vehicles :
Example: sensors in the front bumper,
left-hand side
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
(Y page 344).
