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 position P 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.
