32 Getting startedUnlockingUnlocking with KEYLESS-GO*
If you have the KEYLESS-GO function, your
vehicle checks whether the SmartKey with
KEYLESS-GO is valid when you pull the
door handle. If your SmartKey is valid, the
doors will unlock, and you can open them.
The function of the SmartKey overrules the
KEYLESS-GO function.
Pull the door handle.
The turn signal lamps flash once. The
locking knobs on the doors move up.
If the SmartKey is inside the vehicle, press-
ing the KEYLESS-GO start/stop button on
the gear selector lever corresponds to
turning the SmartKey to the various starter
switch positions.iTo unlock the vehicle, the SmartKey
with KEYLESS-GO must be outside the
vehicle, no further than approx. 3 feet
(1 meter) away from the door.
Warning!
