frequency and infrared remote control, plus removable
mechanical key.
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 main key.
The infrared receivers are located in the door handles.
Note:
Remove the mechanical key from the electronic main
key when using valet parking service. To prevent access
to trunk or storage compartments lock them separately
and retain the mechanical key.

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 buttonŒor‹, 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

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 190), the
message “CHIP-CARD – NOT RECOGNIZED!” will
appear repeatedly in the multifunction display,
seepage318.
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 224.
•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 318.
