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 41).
Starter switch KEYLESS-GO, see page 230.
Starting and turning off the engine with KEYLESS-GO,
see page 236 and page 236.
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.

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
key, see page 371, or synchronize the remote
control, see page 373.
•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 36. Check the batteries of the KEYLESS-
GO-card, see page 374. The trunk lid will open
automatically if a KEYLESS-GO card is detected in
the trunk, see page 36.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 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.

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 briefly – indicating that the batteries are
in order. See page 371 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 ‹, seepage43.
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

Opening the trunk
The trunk lid will swing open automatically. You should
always make sure there is sufficient clearance.
A minimum height clearance of 6 ft. (1.85 m) is
required to open the trunk lid.
Press transmit buttonŠ until trunk lid is open.
Important!
Do not place remote control in trunk since trunk is
locked when the lid is closed if the vehicle is centrally
locked.
Notes:
If the trunk was previously locked separately, it will
remain locked, see page 51.
Vehicles with optional remote trunk lid
opening / closing system, see page 56:
The switch operated opening/closing procedure can be
immediately halted by pressing buttonŠ on the
electronic key.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.

Te ch n i c a l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index •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 198), the
message “CHIP-CARD – NOT RECOGNIZED!” will
appear repeatedly for approx. 2 seconds in the
multifunction display, see page 328.
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. 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 328.
•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 328. 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 44.
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.
