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 in the
KEYLESS-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 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 SmartKey
in the starter switch in the meantime.


This does not apply if, after starting, the
selector lever is still in positionP. The
SmartKey will then have priority over
the card and the vehicle’s electrical
system will operate according to the
position of the SmartKey in the starter
switch, even stopping the engine.
Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take the
KEYLESS-GO card (if so equipped) with you
and lock the vehicle. Do not leave children
unattended in the vehicle, or with access to
an unlocked vehicle. Unsupervised use of
vehicle equipment may cause an accident
and/or serious personal injury.!To prevent possible malfunction, avoid
exposing the KEYLESS-GO card to high
levels of electromagnetic radiation.
