At speeds up to approximately 70 km/h,
PRE-SAFE ®
Brake may also detect stationary
obstacles, for example stoppe dorparked
vehicles. G
Ris
kofa ccident
If, in a critical driving situation, you do not
receive a visual and acoustic warning:
R PRE-SAFE ®
Brake did no tdetec tthe risk of
a collision
R PRE-SAFE ®
Brake is switched off
R PRE-SAFE ®
Brake has failed
You must then brake to avoid a collision.
X To activate/deactivate: activate or deac-
tivate PRE-SAFE ®
Brake in the on-board
computer (Y page 204).
After activation, the Äsymbol is dis-
played on the left in the instrumentc luster.
The radar sensor system is switched off auto-
matically in the vicinity of radio telescope
facilities ( Ypage 327).
Vehicles without COMAND and navigation,
and vehicles for Australia: near radio tele-
scope installations, the radar sensor system
must be switched off with the on-board com-
puter (Y page 210).
For PRE-SAFE ®
Brake to assist you when driv-
ing, the radar sensor system must be
switched on (Y page 210) and operational.
PRE-SAFE ®
Brake does not always detect
complex traffic situations properly. You can
terminate the braking action of PRE-SAFE ®
Brake in a non-critical driving situation at any
time if:
R an acoustic and visual warning occurs.
R the vehicle brakes.
To end this, you can either depress the accel-
erator pedal further, activate kickdown or
release the brake pedal. The braking action of PRE-SAFE
®
Brake is
ended automatically if:
R you manoeuvre to avoid the obstacle.
R you drive slower than approximately
15 km/h.
R there is no longer an obstacle detected in
front of your vehicle.
R there is no longer any dange rofacollision.
Following a collisio norcollision-related dam-
age to the front end of the vehicle, have the
configuration and operation of the radar sen-
sors checked. Choose a qualified specialist
workshop which has the necessary specialist
knowledge and tools for the work required.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. Anti-theft systems
Immobiliser
The immobiliser prevents your vehicle from
being started without the correc tkey.
X To activate with the key: remove the key

X To activate with KEYLESS-GO: switch the
ignition off and open the driver's door.
X To deactivate: switch on the ignition.
i The immobiliser is always deactivated
when you start the engine. ATA (Anti-Theft Alarm system)
Av isual and audible alarm is triggered if the

R a door
R the vehicle with the emergency key ele-
ment
R the boot lid
R the bonnet
The alarm is not switched off, even if you
close the open door that has triggered it, for
example. Anti-theft systems

R the vehicle is unlocked again.
R a door is opened and closed again.
R the vehicle is locked again.
i United Kingdom only: if the vehicle has
been locked with the key, the doors cannot
be opened from the inside (Y page 74).
Deactivate the interior motion sensor
before locking the vehicle with the key. The
doors can then be opened from the inside
after the vehicle has been locked from the
outside with the key. Observe the "Impor-
tant safety notes" (Y page 73). Anti-theft systems

Vehicle equipment
i This manual describes all the standard
and optional equipment of your vehicle
available at the time of publicatio nofthe
Owner's Manual. Country-specific differen-
ces are possible. Please note that your
vehicle may not be equipped with all fea-
tures described. This also applies to safety-
relevant systems and functions. Key
Key functions
Locking and unlocking centrally The key centrally locks/unlocks:
R
the doors
R the boot lid
R the fuel filler flap G
Risk of injury
Only for the United Kingdom: if the vehicle
has been locked with the key, the double lock
function is activated as standard. It is then not
possible to open the doors from inside the
vehicle.
Therefore, do not leave any people behind in
the vehicle, particularly children, elderly peo-
ple or people requiring special assistance, if
the vehicle has been locked with the key. As
a result, they may not be able to free them-
selves in the event of an emergency. They
could be seriously or even fatally injured by
prolonged exposure to extremely high or low
temperatures, for example. In this case, res-
cuing people from outside the vehicle is diffi-
cult.
Deactivate the interior motion sensor before
you lock the vehicle with the key. The doors
can then be opened from the inside after the
vehicle has been locked from the outside with
the key. If the vehicle has been locked with KEYLESS-
GO, the doors can be opened from inside the
vehicle. G
Risk of accident
If children are left unsupervised in the vehicle,
they could:
R open a door from inside the vehicle at any
time, even if it has been locked
R start the vehicle using akey which has been
left in the vehicle
R release the parking brake
They could thereby endanger themselves and
others. Never leave children unsupervised in
the vehicle. Always take the key with you
when leaving the vehicle, even if you are only
leaving it for a short time. :
& To lock the vehicle
; F To unlock the boot lid
= % To unlock the vehicle
When unlocking, the turn signals flash once.
When locking, they flash three times.
When it is dark, the surround lighting also
comes on if it is activated in the on-board
computer.
You can also set an audible signal to confirm
that the vehicle has been locked or unlocked.
The audible signal can be activated and deac-
tivated using the on-board computer
(Y page 209).

ton. 68
KeyOpening and closing

If you do not open
adoor or the boot lid within
approximately 40 seconds of unlocking the
vehicle:
R the vehicle is locked again.
R the anti-theft system is primed again.
X To lock centrally: press the&button. KEYLESS-GO
You can start, lock or unlock the vehicle using
KEYLESS-GO. To do this, you only need carry
the key with you. When you touch the surface
of the sensors on the vehicle's outside door
handles, KEYLESS-GO establishes a radio
connection between the vehicle and the key.
The distance from the door handle with which
you wish to lock or unlock the vehicle must
not be greater than 1 m.
When the engine is started and whilst you are
driving, KEYLESS-GO also checks whether a
valid key is in the vehicle by periodically
establishing radio contact. X
To unlock the vehicle: touch the inner
surface of the door handle.
X To lock the vehicle: touch sensor sur-
face :.
If you pull on the handle of the boot lid, only
the boot of the vehicle is unlocked. Changing the settings of the locking
system
You can change the setting of the locking
system in such a way that only the driver's
door and the fuel filler flap are unlocked. This
is useful if you frequently travel on your own.
X To change the setting: press and hold down
the % and& buttons simultaneously
for approximately six seconds until battery
check lamp (Y page 70) flashes twice.
The key now functions as follows:
X To unlock the driver's door: press the

driver's door.
X To unlock centrally: touch the inner sur-
face of the door handle on the front-
