XBrake immediately to defuse the situation.
or
XTake evasive action provided it is safe to do
so.
Active Brake Assist with cross-traffic function
can also brake the vehicle automatically under
the following conditions:
Rthe driver and front-passenger have their seat
belts fastened
and
Rthe vehicle speed is between approximately
4 mph (7 km/h) and 124 mph (200 km/h)
Up to a speed of approximately 44 mph
(70 km/h), Active Brake Assist with cross-traffic
function may react to:
Rstationary objects in the path of your vehicle,
e.g. stopped or parked vehicles
Rpedestrians in the path of your vehicle
iIf there is an increased risk of a collision,
preventive passenger protection measures
(PRE-SAFE
®) are triggered (Ypage 55).
If the risk of collision with the vehicle in front
remains and you do not brake, take evasive
action or accelerate significantly, the vehicle
may perform automatic emergency braking, up
to the point of full brake application. Automatic emergency braking is not performed until imme-
diately prior to an imminent accident.
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
Ran obstacle is no longer 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
iObserve the "Important safety notes" sec-
tion (Ypage 60).
No steering support is provided from STEER
CONTROL, if:
RESP®is deactivated
RESP®is malfunctioning
Rthe steering is faulty
If ESP®is malfunctioning, you will be assisted
further by the electrical power steering.

Immobilizer
XTo activate with the SmartKey: remove the
SmartKey from the ignition lock.
XTo activate with KEYLESS-GO: switch the
ignition off and open the driver's door.
XTo deactivate: switch on the ignition.
The immobilizer prevents your vehicle from
being started without the correct SmartKey.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. The
engine can be started by anyone with a valid
SmartKey that is left inside the vehicle.
iThe immobilizer is always deactivated when
you start the engine.
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

Optimum use of dual-zone automatic
climate control
Climate control system
The following contains instructions and recom-
mendations to enable you to get the most out of
your 3-zone automatic climate control.
RActivate climate control using the Ãand
¿ buttons on the control panel of the cli-
mate control. The indicator lamps in the Ã
and ¿ buttons light up.
RIn automatic mode, the ñbutton on the
climate control panel may be used to addi-
tionally adjust the airflow (FOCUS/MEDIUM/ DIFFUSE). The MEDIUM level is recommen-
ded.
RSet the temperature to 72 ‡ (22 †).
ROnly use the "Windshield defrosting" function
briefly until the windshield is clear again.
ROnly use air-recirculation mode briefly, e.g. if
there are unpleasant outside odors or when in
a tunnel. The windows could otherwise fog up, since no fresh air is drawn into the vehicle in
air-recirculation mode.
RUse the ZONE function to adopt the temper-
ature settings on the driver's side for the
front-passenger side as well. The indicator
lamp in the ábutton goes out.

Setting climate control to automatic
General notes
In automatic mode, the set temperature is main-
tained automatically at a constant level. The
system automatically regulates the temperature
of the dispensed air, the airflow and the air dis-
tribution.
The automatic mode functions optimally when
the "Cooling with air dehumidification" function
is activated. If necessary, cooling with air dehu-
midification can be deactivated.
If you deactivate the "Cooling with air-dehumid- ification" function, the air inside the vehicle will
not be cooled. The air inside the vehicle will also
not be dehumidified. The windows can fog up
more quickly. Therefore, deactivate the cooling
with air-dehumidification function only briefly.
