Important notes on using KEYLESS-GO

You can also use the SmartKey with
KEYLESS-GO like a normal SmartKey
(page 98).


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.


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 de-
pressed. Do not depress the accel-
erator.


If you have started the engine with the
KEYLESS-GO start/stop button
(page 36), 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
iYou can also open and close the power
windows (
page 218) and tilt/sliding
sunroof* (page 223) or tilt/sliding
panel* (
page 229) using the Smart-
Key.
