door handle. If your SmartKey is valid, the
doors will unlock, and you can open them.
The function of the SmartKey overrules the

The turn signal lamps flash once. The
locking knobs on the doors move up.
The SBC brake system is activated.
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 approximately
3 feet (1 meter) away from the door.
