Important notes on using KEYLESS-GO*
Always carry the KEYLESS-GO card
with you.
Never store the KEYLESS-GO card to-
gether with:
electronic items such as a cellular
phone or another KEYLESS-GO card
metallic objects such as coins or
metal foil
Doing so could impair the function of
the KEYLESS-GO system.
Always take a SmartKey with you in
case of a malfunction of the KEY-
LESS-GO system.
To lock or unlock the vehicle, the card
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
KEYLESS-GO card
the KEYLESS-GO card must be lo-
cated in the vehicle
all the doors must be closed
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 key in the
starter switch in the meantime.
This does not apply if, after starting, the
selector lever is still in position P. The
key will then have priority over the card
and the vehicle's electrical system will
operate according to the position of
the key in the starter switch, even stop-
ping the engine.
If the KEYLESS-GO card is positioned
farther away from the vehicle (e.g. in-
side clothing or briefcase) and can no
longer be recognized by the system,
the vehicle cannot be locked or the en-
gine started via the KEYLESS-GO sys-
tem.

card that is left inside the vehicle. If you
