The remote control (1) operates all locks on the vehicle.
The mechanical key (2) works only in the driver’s door,
trunk, and storage compartment locks.When using the mechanical key (2) for lock operations,
it can be removed by sliding it out of the remote control.
To do so, move locking tab (3) to the right and slide the
mechanical key (2) in direction of arrow (4).
The remote control transmitter is located in the
electronic key.

KEYLESS-GO-card
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 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 42).
Starter switch KEYLESS-GO, see page 230.
Starting and turning off the engine with KEYLESS-GO,
see page 234 and page 234.
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 t hat t hey are always han d y. Never leave t he electro nic
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 or the KEYLESS-
GO-card can only be obtained from your authorized
Mercedes-Benz Center.

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 or a KEYLESS-GO-card.
If the vehicle cannot be locked or unlocked:
•Aim transmitter eye at a receiver on either door
handle. Check the batteries of the electronic key, see
page 369, or synchronize the remote control,
seepage371.
•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 approximately
3 ft. (1 m). Check the location of the KEYLESS-GO-
card, see page 37. Check the batteries of the
KEYLESS-GO-card, see page 372. The trunk lid will
ope n automatically if a KEYLESS -GO c ar d 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.

Radio frequency and infrared remote control
The electronic 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 brief ly – indicating that the batteries are
in order. See page 369 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 buttonŒ or‹, seepage44.
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

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
t he start/stop button function, t he KEYLE SS-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,
seepage324.
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 period 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 230.
•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 324.

•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 324.
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
s o t hat t hey ar e always han dy. Never leave t he e le ctron ic
key in the vehicle.Notes:
The KEYLESS-GO-function also permits closing of
windows and sliding/pop-up roof (convenience feature),
see page 45.
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.
