The front door windows are equipped with
automatic operation and the anti-entrapment
feature. If in automatic mode a front door
window encounters an obstruction that
blocks its path, the anti-entrapment feature
will stop the door window and open it slightly.
The door windows operate differently when

are riding in the back seats of the vehicle. The
children may otherwise injure themselves,
e.g. by becoming trapped in the door window
opening.GWARNING
Do not keep any part of your body up against
the window pane when opening a window. The
downward motion of the pane may pull that

Obstructions and stationary vehicles
DISTRONIC PLUS does not brake for
obstacles or stationary vehicles. If, for
example, the detected vehicle turns a corner
and reveals an obstacle or stationary vehicle,
DISTRONIC PLUS will not brake for these.
Crossing vehicles
DISTRONIC PLUS may mistakenly detect
vehicles that are crossing your lane.
Activating DISTRONIC PLUS at traffic lights
with crossing traffic, for example, could cause
your vehicle to pull away unintentionally.
HOLD function

following situations:
R when pulling away, especially on steep
slopes

R when waiting in traffic
The vehicle is kept stationary without the

R the vehicle is stationary.
R the driver's door is closed or your seat belt
is fastened.

HOLD function is activated. For this reason,
deactivate the HOLD function if the vehicle is
to be set in motion by other means (e.g. in a
car wash or by towing).
