EBD (electronic brake force distribu-
tion)
General information
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking.
Important safety notes
iObserve the "Important safety notes" sec-
tion for driving safety systems (
Ypage 61).
GWARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the
risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (
Ypage 243) as well as dis-
play messages (
Ypage 214).
ADAPTIVE BRAKE
i
Observe the "Important safety notes" sec-
tion (
Ypage 61).
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In addi- tion to the braking function, ADAPTIVE BRAKE
also has the HOLD function (
Ypage 179) and
hill start assist (
Ypage 142).

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 star-
ted (yet the vehicle's battery is charged),
the system 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).

The SmartKey centrally locks/unlocks:
Rthe doors
Rthe trunk lid
Rthe stowage compartment in the center
console
Rthe fuel filler flap
The turn signals flash once when unlocking
and three times when locking.
You can also set an audible signal to confirm
that the vehicle has been locked. The audible
signal can be activated and deactivated using the on-board computer (
Ypage 206).
When it is dark, the surround lighting also
comes on if it is activated in the on-board
computer (
Ypage 205).
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.
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 functions of KEYLESS-GO with those of a con-
ventional SmartKey. Unlock the vehicle by
using KEYLESS-GO, for instance, and lock it
using the &button on the SmartKey.
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).
A check which periodically establishes a radio
connection between the vehicle and the
SmartKey determines whether a valid Smart-
Key is in the vehicle. This occurs, for example:
Rwhen the external door handles are
touched
Rwhen starting the engine
Rwhile the vehicle is in motion
XTo unlock the vehicle: touch the inner
surface of the door handle.
XTo lock the vehicle: touch sensor sur-
face :.
XConvenience closing feature: touch
recessed sensor surface ;for an exten-
ded period.
Further information on the convenience
closing feature (
Ypage 85).
XTo unlock the trunk lid: pull the handle on
the trunk lid.
The vehicle only unlocks the trunk lid.
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.
XTo deactivate: press the&button on
the SmartKey twice in rapid succession.
The battery check lamp (
Ypage 75) of the
SmartKey flashes twice briefly and lights up
once, then KEYLESS-GO is deactivated.
XTo activate: press any button on the
SmartKey or insert the SmartKey into the
ignition lock.
KEYLESS-GO and all of its associated fea-
tures are available again.

Side windows
Important safety notes
GWARNING
While opening the side windows, body parts
could become trapped between the side win-
dow and the door frame as the side window
moves. There is a risk of injury.
Make sure that nobody touches the side win-
dow during the opening procedure. If some-
body becomes trapped, release the switch or
pull the switch to close the side window again.
GWARNING
While closing the side windows, body parts in
the closing area could become trapped. There is a risk of injury.
When closing make sure that no parts of the
body are in the closing area. If somebody
becomes trapped, release the switch or press
the switch to open the side window again.
GWARNING
If children operate the side windows they
could become trapped, particularly if they are left unsupervised. There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
Side window reversing feature
The front side windows are equipped with an
automatic reversing feature. If a solid object
blocks or restricts one of the front side win-
dows from traveling upwards during the auto-
matic closing process, the side window opens
again automatically. During the manual clos-
ing process, the side window only opens
again automatically after the corresponding
switch is released. 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.
GWARNING
The reversing feature does not react:
Rto soft, light and thin objects, e.g. small fin-
gers
Rwhile resetting
This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.
Make sure that no body parts are in close
proximity during the closing procedure. If
someone becomes trapped, press the switch
to open the side window again.
Opening and closing the side win-
dows in the front
The switches for the front side windows are
located on the driver's door. There is also a
switch for the front-passenger side window
on the front-passenger door.

Problems with the side windows
GWARNING
If you close a side window again immediately after it has been blocked or reset, the side window
closes with increased or maximum force. The reversing feature is then not active. Parts of the
body could be trapped in the closing area in the process. This poses an increased risk of injury or
even fatal injury.
Make sure that no parts of the body are in the closing area. To stop the closing process, release
the switch or push the switch again to reopen the side window.
ProblemPossible causes/consequences and MSolutions
A side window cannot
be closed because it is
blocked by objects, e.g.
leaves in the window
guide.XRemove the objects.
XClose the side window.
A side window cannot
be closed and you can-
not see the cause.If a side window is obstructed during closing and reopens again
slightly:
XImmediately after the window blocks, pull the corresponding
switch again until the side window has closed.
The side window is closed with increased force.
If a side window is obstructed again during closing and reopens
again slightly:
XImmediately after the window blocks, pull the corresponding
switch again until the side window has closed.
The side window is closed without the anti-entrapment feature.
Roof
Important safety notes
GWARNING
If you do not fully open/close the soft top, the
soft-top hydraulics depressurize after a short
time. This causes the soft top to lower unex-
pectedly and may cause you or others to be
trapped. There is a risk of injury.
Always open or close the soft top completely.
GWARNING
Closing the roof manually is a complicated
and technically demanding procedure, which
requires a lot of strength. You or others can
become trapped. There is a risk of injury.
Only have the soft top closed manually at a
qualified specialist workshop.
!Never sit on the rear shelf or store heavy
objects there. You will otherwise damage
the roof and the rear shelf of your vehicle.
!Do not forget that the weather can
change abruptly. Make certain that the roof
is closed when you leave the vehicle. The
vehicle electronics can be damaged if
water enters the vehicle interior.
!When opening and closing the roof, make
sure that:
