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.

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.

Locking and unlocking with KEYLESS-GO-card
Unlocking:
Grasp any door handle. All turn signal lamps blink once
to indicate that the vehicle is unlocked.
The KEYLESS-GO-card can be programmed for two
kinds of unlocking modes (see below):
Selective unlocking mode –
Grasp driver’s door handle to unlock driver’s door and
fuel filler flap.
Grasping the passenger door or a rear door, centrally
unlocks the vehicle.
Global unlocking mode –
Grasp any door handle to unlock both doors, fuel filler
flap, and trunk.
For choosing global or selective mode on KEYLESS-GO-
card, see page 43.Notes:
The door which was unlocked, can be opened
immediately after the audible click. The other door can
be opened after its lock button rises up.
If the trunk was previously locked separately, it will
remain locked, see page 53.
The presently active unlocking mode (selective or
global) can be determined by pressing the button on the
KEYLESS-GO-card (see page 43 for changing mode).
If within 40 seconds of unlocking with the
KEYLESS-GO-card, 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.
