Start lock-out
Important!
Operating with electronic key:
Removing the electronic key from the starter switch
activates the start lock-out. The engine cannot be
started.
Inserting the electronic key in the starter switch
deactivates the start lock-out.
Operating with KEYLESS-GO:
Turning off the engine with the start- / stop button on
the gear selector lever activates the start lock-out. For
turning off the engine with KEYLESS-GO, see page 232.
Starting the engine with the start- / stop button
deactivates the start lock-out, if a valid KEYLESS-GO-
card is recognized inside the vehicle. For starting the
engine with KEYLESS-GO, see page 231. The engine
cannot be started with a KEYLESS-GO-card outside the
vehicle.Note:
In case the engine cannot be started (vehicle’s battery is
in order), 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).

Te ch n ica l
data Instruments

cluster displayPractical hints Car care Index General notes on the central locking system
If the electronic key is inserted in the starter switch, the
vehicle cannot be locked or unlocked with the remote
control.
If the vehicle cannot be locked or unlocked:
•Aim transmitter eye at a receiver on either front
door handle. Check the batteries of the electronic
main key, see page 363, or synchronize the remote
control, see page 365.
•Use the mechanical key to unlock the vehicle. To
start engine, insert the electronic key in the starter
switch. There could be a slight delay until the
electronic key can be turned in the starter switch.
•Vehicles with KEYLESS-GO only:
A KEYLESS-GO-card must be recognized by the
system as being outside the vehicle to enable the
vehicle to be locked or unlocked (maximum distance
between card and doors or trunk is approx. 3 ft.
(1 m). Check the location of the KEYLESS-GO-card,
see page 38. Check the batteries of the KEYLESS-
GO-card, see page 366. The trunk lid will open
automatically if a KEYLESS-GO card is detected in
the trunk, see page 38.Note:
If neither the remote control nor KEYLESS-GO system
functions, use the mechanical key to unlock or lock the
vehicle. To start engine, insert the electronic key in the
starter switch. There could be a slight delay until the
electronic key can be turned in the starter switch.
Important!
When unlocking the driver’s door with the mechanical
key, the exterior lamps will flash and the alarm will
sound.
To cancel the alarm, insert the electronic key in the
starter switch, or press buttonŒ or‹ on the
electronic main key; or with the optional KEYLESS-GO-
system, when carrying a KEYLESS-GO-card, by grasping
a door handle or pressing the start- / stop button on the
gear selector lever.

Central locking system
Radio frequency and infrared remote control
The electronic main key has an integrated radio
frequency and infrared remote control.
Due to the extended operational range of the remote
control, it could be possible to unintentionally lock or
unlock the vehicle by pressing the transmit button. If
one of the transmit buttons is pressed, the battery check
lamp lights up briefly – indicating that the batteries are
in order. See page 363 for checking batteries.
The vehicle doors, trunk and fuel filler flap can be
centrally locked and unlocked via remote control.
Opening and closing the windows and sliding/pop-up
roof and switching on the driver’s seat ventilation can
only be done with the infrared portion of the remote
control. Aim transmitter eye at a receiver (6 or 7), press
and hold transmit button Œor ‹, see page 45.
With vehicle centrally locked, the trunk can also be
opened by using the remote control.
If the electronic key is inserted in starter switch, the
vehicle cannot be locked or unlocked, and the trunk lid
cannot be opened with the remote control.1Transmit button

Locking and unlocking with remote control
Unlocking:
Press transmit button Œ. All turn signal lamps blink
once to indicate that the vehicle is unlocked.
The remote control can be programmed for two kinds of
unlocking modes (see below):
Selective unlocking mode –
Press transmit button Œ once to unlock driver’s door
and fuel filler flap.
Press transmit button Œ twice to unlock all doors,
fuel filler flap, and trunk.
Global unlocking mode –
Press transmit button Œ once to unlock all doors,
fuel filler flap, and trunk.
Notes:
If the trunk was previously locked separately, it will
remain locked, see page 53.
The presently active unlocking mode (selective or
global) can only be determined by unlocking the vehicle
with the remote control (see below for changing mode).If within 40 seconds of unlocking with the remote
control, neither door nor trunk is opened, the electronic
key is not inserted in the starter switch, or the central
locking switch is not activated, the vehicle will
automatically lock.
Locking:
Press transmit button ‹ once. All turn signal lamps
blink three times to indicate that the vehicle is locked. If
they do not blink three times, a door or trunk is not
properly closed.
Note:
If the vehicle cannot be locked or unlocked by pressing
the transmit button, then it may be necessary to change
the batteries in the electronic main key (if ok, battery
check lamp in electronic main key will light briefly
when pressing transmit button) or to synchronize the
remote control, see pages 363 and 365.
