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:
R stationary obstacles in the path of the vehicle,
e.g. stopped or parked vehicles
R stationary pedestrians in the path of the vehi-
cle
R obstacles crossing your path that move in the
detection range of the sensors and are detec- ted
X Keep 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:
R depressing the accelerator pedal further
R activating kickdown
R releasing the brake pedal
The braking application of Active Brake Assist
with cross-traffic function is ended automati-
cally if:
R you maneuver to avoid the obstacle
R there is no longer a risk of collision
R there 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:
R both right wheels or both left wheels are on a
wet or slippery road surface when you brake
R the vehicle starts to skid
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 66). No steering assistance is provided from STEER
CONTROL, if:
R ESP ®
is deactivated
R ESP ®
is malfunctioning
R the steering is malfunctioning
If ESP ®
is malfunctioning, you will be assisted
further by the electrical power steering. Protection against theft
Immobilizer
X To activate with the SmartKey: remove the
SmartKey from the ignition lock.
X To activate with KEYLESS-GO: switch the
ignition off and open the driver's door.
X To 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. Anyone
can start the engine if a valid SmartKey has been left inside the vehicle.
i The 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
1-800 FOR-MERCEDES (in the USA) or
1-800-387-0100 (in Canada). ATA (anti-theft alarm system) Protection against theft

X To open the tailgate automatically from
outside the vehicle:
press and hold the0054
button until the tailgate opens.
Vehicles with KEYLESS-GO: X To close the tailgate automatically from
outside the vehicle:
if the SmartKey is loca-
ted in the immediate vicinity of the vehicle,
press the 0054button on the SmartKey.
When the tailgate closes you can then release
the button. KEYLESS-GO
General notes Bear in mind that the engine can be started by
any of the vehicle occupants if there is a KEY-
LESS-GO key in the vehicle (Y page 137).
Locking/unlocking centrally You can start, lock or unlock the vehicle using
KEYLESS-GO. To do this, you only need carry the
SmartKey with you. You can combine the func-
tions of KEYLESS-GO with those of a conven-
tional SmartKey. Unlock the vehicle by using
KEYLESS-GO, for instance, and lock it using the 0037 button on the SmartKey.
The driver's door and the door at which the han- dle is used, must both be closed. The SmartKey
must be outside the vehicle. When locking or
unlocking with KEYLESS-GO, the distance
between the SmartKey and the corresponding
door handle must not be greater than 3 ft (1 m).
KEYLESS-GO checks whether a valid SmartKey
is in the vehicle by periodically establishing a
radio connection between the vehicle and the
SmartKey. This happens:
R when starting the engine
R while driving
R when the external door handles are touched
R during convenience closing X
To unlock the vehicle: touch the inner sur-
face of the door handle.
X To lock the vehicle: touch sensor surface 0043
or 0044.
Make sure that you do not touch the inner
surface of the door handle.
X Convenience closing feature: touch
recessed sensor surface 0044for an extended
period.
Further information on the convenience closing
feature (Y page 90).
If you pull on the handle of the tailgate, only the cargo compartment of the vehicle is unlocked.
Deactivating and activating If you do not intend to use a SmartKey for an
extended period of time, you can deactivate the
KEYLESS-GO function of the SmartKey. The
SmartKey will then use very little power, thereby conserving battery power. For the purposes of
activation/deactivation, the vehicle must not be
nearby.
X To deactivate: press the0037button on the
SmartKey twice in rapid succession.
The battery check lamp of the SmartKey
flashes twice briefly and lights up once, KEY-
LESS-GO is deactivated (Y page 80).
X To activate: press any button on the Smart-
Key.
or X Insert the SmartKey into the ignition lock.
KEYLESS-GO and all of its associated features are available again. 78

WARNING
If objects, luggage or loads are not secured or not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, particu-
larly in the event of sudden braking or a sud-
den change in direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
! The tailgate swings upwards and to the rear
when opened. Therefore, make sure that
there is sufficient clearance above and behind
the tailgate.
The opening dimensions of the tailgate can be
found in the "Vehicle data" section
(Y page 390).
You should preferably place luggage or loads in the cargo compartment. Observe the loading
guidelines (Y page 295).
Do not leave the SmartKey in the cargo com-
partment. You could otherwise lock yourself
out.
Vehicles without the EASY-PACK tailgate:
the tailgate can be:
R opened and closed manually from outside
R unlocked from inside with the emergency
release
For vehicles with the EASY-PACK tailgate:
you can:
R close the tailgate manually from outside
R open the tailgate automatically from outside
R open and close the tailgate automatically
from inside
R unlock the tailgate from inside with the emer-
gency release
R limit the opening angle of the tailgate Tailgate reversing feature
On vehicles with the tailgate remote closing fea- ture, the tailgate is equipped with automatic
obstacle recognition with a reversing feature. If a solid object blocks or restricts the tailgate
when automatically opening or closing, this pro-
cedure is stopped. If the tailgate is stopped dur- ing the closing procedure, it will open again automatically. The automatic obstacle recogni-
tion with reversing feature is only an aid. It is not
a substitute for your attentiveness when open-
ing and closing the tailgate. G
WARNING
The reversing feature does not respond:
R to soft, light and thin objects, e.g. fingers
R over the last 00C2in (8 mm) of the closing
movement
The reversing feature cannot prevent some-
one from becoming trapped in these situa-
tions in particular. There is a risk of injury.
Make sure that no body parts are in close
proximity during the closing procedure.
If somebody becomes trapped:
R press the 0054button on the SmartKey, or
R pull or press the remote operating switch
on the driver's door or
R press the closing or locking button on the
tailgate or
R pull the handle on the tailgate Opening and closing manually from

WARNING
If children operate the side windows they
could become trapped, particularly if they are left unsupervised. There is a risk of injury.
Activate the override feature for the rear side
windows. When leaving the vehicle, always
take the SmartKey with you and lock the vehi-
cle. Never leave children unsupervised in the
vehicle. Side window reversing feature
The side windows are equipped with an auto-
matic reversing feature. If a solid object blocks
or restricts a side window during the closing
process, the side window opens again automat-
ically. However, the automatic reversing feature is only an aid and does not relieve you of the
responsibility of paying attention when closing a side window. G
WARNING
The reversing feature does not react:
R to soft, light and thin objects, e.g. small fin-
gers
R over the last 1/6 in(4 mm) of the closing
movement
R during resetting
R when closing the side window again man-
ually immediately after automatic reversing
This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.

Important safety notes
Your vehicle may be equipped with a sliding
sunroof or a panorama roof with power tilt/slid- ing panel. In the following section, the term
"sliding sunroof" refers to both sliding sunroof
variants. G
