102 Controls in detailLocking and unlockingImportant notes on using KEYLESS-GO*
You can also use the SmartKey with
KEYLESS-GO like a normal SmartKey
(page 96).
You can combine KEYLESS-GO func-
tions with normal SmartKey functions
(e.g. unlocking with KEYLESS-GO and
locking with the ‹button).
Always carry the SmartKey with
KEYLESS-GO with you.
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 ap-
proximately 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 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
(page 35), 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
gear 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 accord-
ing 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.
