Power Door Locks (If Equipped)
If your vehicle has power door locks, the switch is
located on the armrest. Remove the ignition key and
press LOCK to lock all the doors at once.
To unlock the doors, press the raised area next to the
key symbol.
-
On four door models, the switch on each rear door
works only that door's lock.
Rear Door Security Lock (If Equipped)
Move the lever up to lock the doors and down to release
the door locks.
Lockout Prevention
This feature stops the power door locks from locking
when the keys are in the ignition and a door is open, to
protect you from locking your key in the vehicle.
If the power lock switch is pressed when a door is open
and the key is in the ignition, all the doors will lock and
the driver's door will unlock.
With this feature, you can
lock the rear doors so they
can't be opened from the
inside by passengers.
