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.

Locking and unlocking with remote control
Unlocking:
Press transmit button Œ. All turn signal lamps blink
once to indicate that the vehicle is unlocked.
The remote control can be programmed for two kinds of
unlocking modes (see below):
Selective unlocking mode –
Press transmit button Œ once to unlock driver’s door
and fuel filler flap.
Press transmit button Πtwice to unlock all doors,
fuel filler flap, and trunk.
Global unlocking mode –
Press transmit button Πonce to unlock all doors,
fuel filler flap, and trunk.
Notes:
If the trunk was previously locked separately, it will
remain locked, see page 53.
The presently active unlocking mode (selective or
global) can only be determined by unlocking the vehicle
with the remote control (see below for changing mode).If within 40 seconds of unlocking with the remote
control, 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.
Locking:
Press transmit button ‹ once. All turn signal lamps
blink three times to indicate that the vehicle is locked. If
they do not blink three times, a door or trunk is not
properly closed.
Note:
If the vehicle cannot be locked or unlocked by pressing
the transmit button, then it may be necessary to change
the batteries in the electronic main key (if ok, battery
check lamp in electronic main key will light briefly
when pressing transmit button) or to synchronize the
remote control, see pages 363 and 365.

Press and hold transmit buttons‹ andŒ
simultaneously for five seconds to reprogram the
remote control. Battery check lamp will blink two times

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:

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.

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).
