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 positionP. 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.


If the KEYLESS-GO card is removed
from the vehicle while the ignition is
switched on (e.g. if passenger exits the
vehicle with the card), the message Chip card not recognized!
will ap-
pear in the multifunction display.
Find the card or change its present lo-
cation 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 KEYLESS-GO
card that is left inside the vehicle. If you
leave the card behind when exiting and
locking the vehicle, the message
Chip
card still in vehicle!
will appear in
the multifunction display.
