Up to a speed of approximately 44 mph
(70 km/h) the Active Brake Assist with cross-
traffic function assists you with braking in haz-
ardous situations with:
Rstationary obstacles in the path of the vehicle,
e.g. stopped or parked vehicles
Rstationary pedestrians in the path of the vehi-
cle
Robstacles crossing your path that move in the
detection range of the sensors and are detec-
ted
XKeep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
You can prevent the intervention of Active Brake
Assist with cross-traffic function at any time by:
Rdepressing the accelerator pedal further
Ractivating kickdown
Rreleasing the brake pedal
The braking application of Active Brake Assist
with cross-traffic function is ended automati-
cally if:
Ryou maneuver to avoid the obstacle
Rthere is no longer a risk of collision
Rthere is no longer an obstacle detected in
front of your vehicle
STEER CONTROL
General information
STEER CONTROL helps you by transmitting a
noticeable steering force to the steering wheel
in the direction required for vehicle stabilization.
This steering assistance is provided in particular
if:
Rboth right wheels or both left wheels are on a wet or slippery road surface when you brake
Rthe vehicle starts to skid
Important safety notes

tion (Ypage 63). No steering assistance is provided from STEER
CONTROL, if:
RESP®is deactivated

Rthe steering is malfunctioning
If ESP®is malfunctioning, you will be assisted
further by the electrical power steering.

In the event that the engine cannot be started
(yet the vehicle's battery is charged), the sys-
tem is not operational. Contact an authorized
Mercedes-Benz Center or call

General notes
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking position P.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
The function of the electric parking brake is
dependent on the on-board voltage. If the on-
board voltage is low or there is a malfunction in
the system, it may not be possible to apply the
released parking brake.
XIf this is the case, only park the vehicle on
level ground and secure it to prevent it rolling
away.
XShift the automatic transmission to position
P.
It may not be possible to release an applied
parking brake if the on-board voltage is low or
there is a malfunction in the system. Contact a
qualified specialist workshop.
iThe electric parking brake performs a func-
tion test at regular intervals while the engine
is switched off. The sounds that can be heard
while this is occurring are normal.
