R If the SmartKey with KEYLESS-GO is posi-
tioned farther away from the vehicle, the
system may no longer recognize the Smart-
Key with KEYLESS-GO. The vehicle cannot
be locked or the engine started via the KEY-
LESS-GO system.
R If the SmartKey with KEYLESS-GO is
removed from the vehicle while the engine
is running (e.g. if a passenger exits the
vehicle with the SmartKey with KEYLESS-
GO), the message
Key Not Detected
appears in the multifunction display while
driving off.
Find the SmartKey with KEYLESS-GO or
change its present location immediately
(e.g. place it on the passenger seat or insert
it in shirt pocket).
R If you have started the engine with the KEY-
LESS-GO start/stop button, you can only
turn it off again with this button, even if you
have put the SmartKey in the starter switch
in the meantime.
R This does not apply if, after starting, the
automatic transmission is still in park posi-
tion
P and the SmartKey is then inserted in
the starter switch. The SmartKey will then
have priority over the KEYLESS-GO func-
tion and the vehicle’s electrical system will
operate according to the position of the
SmartKey in the starter switch, even stop-
ping the engine.
R The vehicle could be inadvertently
unlocked if the SmartKey with KEYLESS-
GO is within 3 ft (1 m) of the vehicle and
- an outside door handle is splashed with
water
or
- you attempt to clean an outside door
handle
R Remember that the engine can be started
by anyone with a SmartKey with KEYLESS-
GO that is left inside the vehicle. If you leave
the SmartKey with KEYLESS-GO behind
when exiting and locking the vehicle, the
message Key Detected In Vehicle
appears in the multifunction display.
