vehicle checks whether the SmartKey with 
KEYLESS-GO is valid when you pull the

doors will unlock, and you can open them.

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!

SmartKey with KEYLESS-GO with you, and 
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an 
unlocked vehicle. Unsupervised use of vehi-
cle equipment may cause an accident 
and/or serious personal injury.
