locks

3. Close the door
2. Move the lever down
to engage the safety
lock. Move the lever
up to disengage
the safety lock.
The rear doors of your vehicle cannot be opened from
the inside when this feature is in use. If you want to
open the rear door when the security lock is on, unlock
the door and open the door from the outside.
Lockout Protection
This feature stops the power door locks from locking
when the key is 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 then the driver's door will unlock.
Leaving Your Vehicle
If you are leaving the vehicle, take your key, open your
door and set the lock from inside. Then get out and
close the door.
4. Do the same thing to the other rear door.
