Locking and unlocking


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


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

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


All doors must be closed.


The brake pedal must be firmly de-
pressed. Do not depress the accel-
erator.


If you have started the engine with the
KEYLESS-GO start/stop button, you
can only turn it off again with this but-
ton, 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
the SmartKey is then 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 then cannot be locked or
the engine started via the KEYLESS-GO
system.


If the SmartKey with KEYLESS-GO is re-
moved from the vehicle while the en-
gine is running (e.g. if passenger exits
the vehicle with the SmartKey), the
message
Key not recognized!
will ap-
pear 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
recognized in vehicle!
will appear in
the multifunction display.
