windows are covered with ice, the side
windows will not move up or down. In
this case, you will not be able to close
the door. Do not try to close the door
with force. The door or the window
could otherwise be damaged.!To prevent possible malfunction, avoid
exposing the SmartKey with

106 Controls in detailLocking and unlocking

Never store the SmartKey with
KEYLESS-GO together with:

electronic items such as a cellular
phone or another SmartKey with
KEYLESS-GO


metallic objects such as coins or
metal foil
Doing so could impair the function of
the KEYLESS-GO system.


To lock or unlock the vehicle, the
SmartKey with KEYLESS-GO must be
located outside the vehicle within
approximately 3 ft (1 m) of a door or
the trunk lid.


In order to start the engine with the
SmartKey with KEYLESS-GO:

The SmartKey with KEYLESS-GO
must be located in the vehicle.


All the doors must be closed.


The brake pedal must be firmly
depressed. Do not depress the
accelerator.


If you have started the engine with the
KEYLESS-GO start/stop button
(page 38), you can only turn it off
again with this button, even if you have
put the SmartKey in the starter switch
in the meantime.
This does not apply if, after starting, the
selector lever is still in positionP and
then the SmartKey is inserted in the
starter switch. The SmartKey will then
have priority over the KEYLESS-GO
function and the vehicle’s electrical
system will operate according to the
position of the SmartKey in the starter
switch, even stopping the engine.


If the SmartKey with KEYLESS-GO is
positioned farther away from the vehi-
cle, the system may no longer recog-
nize the SmartKey with KEYLESS-GO.
The vehicle cannot be locked or the
engine started via the KEYLESS-GO
system.


If the SmartKey with KEYLESS-GO is
removed from the vehicle while the
ignition is switched on (e.g. if passen-
ger exits the vehicle with the SmartKey
with KEYLESS-GO), the message Key not recognized
will appear in the
multifunction display while driving off.
Find the SmartKey or change its
present location immediately (e.g.
place it on the front passenger seat or
insert it in shirt pocket).


Remember that the engine can be
started by anyone with a SmartKey
with KEYLESS-GO that is left inside the
vehicle. If you leave the SmartKey with
KEYLESS-GO behind when exiting and
locking the vehicle, the message Key still in vehicle
will appear in
the multifunction display.
