door is open and the key is in the
ignition, all of the doors will lock and
then the driver door will unlock.
If the passenger side power door
lock switch is pressed when the

doors will lock and then the front
passenger door will unlock.

Safety Locks

Liftgate

Warning
Exhaust gases can enter the
vehicle if it is driven with the
liftgate or trunk/hatch open,
or with any objects that pass
through the seal between the
body and the trunk/hatch or
liftgate. Engine exhaust contains
carbon monoxide (CO) which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle must be driven with
the liftgate or trunk/hatch open:
Close all of the windows.
Fully open the air outlets on
or under the instrument
panel.
