The KEYLESS-GO-card (1) does not have a removable
mechanical key.
The functions of the KEYLESS-GO-card (1) are identical
to those of the electronic main key. Carrying the card
with you permits the use of the vehicle.The validity of the KEYLESS-GO-card is checked every
time when grasping a door handle or pushing the trunk
lid release. Once the KEYLESS-GO-card is recognized
outside the vehicle, the doors, trunk lid and fuel filler
flap are unlocked, depending on the selected mode
(global or selective unlocking mode, see page 43).
Starter switch KEYLESS-GO, see page 228.
Starting and turning off the engine with KEYLESS-GO,
see page 231 and page 232.
Note:
In the case of a malfunction in the KEYLESS-GO-system,
we recommend that you carry the electronic key plus
mechanical key with you and keep them in a safe place
so that they are always handy. Never leave the electronic
key or a KEYLESS-GO-card in the vehicle.
Obtaining replacement keys
Your vehicle is equipped with a theft deterrent locking
system requiring a special key manufacturing process.
For security reasons, replacement keys can only be
obtained from your authorized Mercedes-Benz Center.

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

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.

KEYLESS-GO
Important!
For the KEYLESS-GO-system to function properly, the
operator should observe the following:
•The driver should carry the KEYLESS-GO-card with
him / her.
•To avoid radio transmission interference, never store
the KEYLESS-GO-card together with other electronic
items (e.g. cellular telephones, other KEYLESS-GO-
cards) or metallic objects (e.g. coins, metal foil).
•To lock or unlock the vehicle, the card must be
recognized by the system as being located outside
the vehicle. The card must be in close proximity to a
door or the trunk lid (approx. 3 ft. [1 m]). To activate
the start / stop button function, the KEYLESS-GO-
card must be recognized by the system as being
located inside the vehicle.
•If the KEYLESS-GO-card is positioned farther away
from the vehicle (e.g. inside clothing or a briefcase)
and can no longer be recognized by the system, the
vehicle cannot be locked or the engine started via
the KEYLESS-GO-system.•If the KEYLESS-GO-card is removed from the vehicle
while the engine is running, or by placing the card
in front of the center armrest (see page 195), the
message “CHIP-CARD – NOT RECOGNIZED!” will
appear repeatedly in the multifunction display,
seepage322.
Find the card or change its present location (e.g.
place it on the front passenger seat or insert it in
shirt pocket).
•If the message “CHIP - CARD – NOT RECOGNIZED”
is ignored for an extended of time (approx.
15 minutes), the engine could stop by itself during a
vehicle stop (e.g. traffic light). The vehicle can then
no longer be centrally locked or the engine
restarted. You must first find the card or change its
present location (e.g. place it on the front passenger
seat or insert it in shirt pocket). Start the engine
again. See page 228.
•Do not forget, the engine can be started by anyone
with a KEYLESS-GO-card that is left inside the
vehicle. Leaving the chip-card behind when exiting
and locking the vehicle, the message “CHIP-CARD –
STILL IN VEHICLE” appears in the multifunction
display, see page 322.

cluster displayPractical hints Car care Index •Opening the driver’s door with the engine shut off
and no electronic key in the starter switch, the
message “CHIP-CARD – DO NOT FORGET” appears
as a reminder, see page 322.
Important!
In the case of a malfunction in the KEYLESS-GO-system,
we recommend that you carry the electronic key plus
mechanical key with you and keep them in a safe place
so that they are always handy. Never leave the electronic
key in the vehicle.Notes:
The KEYLESS-GO-function also permits closing of
windows and sliding / pop-up roof (convenience feature),
see page 46.
With the KEYLESS-GO-card in close proximity (approx.
3 ft. [1 m]) of the vehicle, aiming a jet of water at a door
handle (e.g. when washing the vehicle) or cleaning
snow from a door could lock or unlock the vehicle
inadvertently.
To prevent a possible inadvertent lockout, the trunk lid
will open automatically if a KEYLESS-GO-card is
recognized in the area of the rear shelf or inside the
trunk.

Simultaneous use of electronic key and
KEYLESS-GO-card
When using the electronic key and the KEYLESS-GO-
card at the same time, the electronic key overrules the
KEYLESS-GO-card.
If the engine is started with the start- / stop button on
the gear selector lever, and afterwards the electronic
key is inserted in the starter switch, the engine
continues to run with the gear selector lever in positions
“R”, “N”, “D” plus ranges “4”, “3”, “2”, “1” until it is
stopped by using the start- / stop button on the gear
selector lever.If the electronic key is inserted in the starter switch
while the gear selector lever is in position “P”, the
electronic key takes over. The vehicle operates
according to the electronic key position in the starter
switch (see page 226), eventually even stopping the
engine.
Wa r n i n g !
When leaving the vehicle always remove the
electronic key from the starter switch, take the
KEYLESS-GO-card with you, and lock your vehicle.
Unsupervised use of vehicle equipment may cause
serious personal injury.

wheel tilts upwards to allow easier entry into and exit
from the vehicle when the driver’s door is opened.
However, the engine must be turned off.
When the electronic key is inserted in the starter switch
or, with a valid KEYLESS-GO-card, when pressing the
start- / stop button on the gear selector lever, and if the
driver’s door is closed, the steering wheel returns to the
last position set for it.
Wa r n i n g !
You must ensure that no one can become trapped
or injured by the moving steering wheel when the
easy-entry / exit feature is in operation and you
open the driver’s door or remove the electronic key
from the starter switch. Do not leave children
unattended in the vehicle, or with access to an
unlocked vehicle. Unsupervised use of vehicle
equipment may cause serious personal injury.
