Locking and unlocking
Warning! G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. It is possible
for children to open a locked door from the
inside, which could result in an accident
and/or serious personal injury.
i
When you open a door, the side window on
that side lowers slightly. Once you close the
door, the window moves up again.
!
The side windows will not open or close if
the battery is discharged or the windows are cov-
ered with ice. As a result, you may no longer be
able to properly close the door. Do not attempt
to force the door shut. Doing so may damage the
door or the side window. Correct the condition
that prevents the windows from operating before
attempting to close the door.
