Keys and Locks
LOCK TAB
Each front door has a lock tab on the
top. When you push down the lock
tab on the driver's door, all the doors
and the tailgate lock. Pulling up the
lock tab on the driver's door unlocks
only that door. The lock tab on the
front passenger's door locks and
unlocks only that door.
To lock the front passenger's door
when getting out of the vehicle, push
the lock tab down and close the door.
Instruments and Controls
To lock the driver's door, along with
the remaining doors and the tailgate,
push the lock tab down or push the
master switch down, then close the
door.
All doors and the tailgate can be
locked from the outside by using the
key in either front door. To unlock
only the driver's door from the
outside, turn the key and release it.
If you turn the key and hold it, all
doors and the tailgate will unlock. All
four doors and the tailgate will
unlock when you unlock the
passenger's door with the key.
Lockout Prevention
If you forget and leave the key in the
ignition switch, Lockout Prevention
will not allow you to lock the driver's
door. With the driver's door open
and the key in the ignition, both
master door lock switches are
disabled. However, if the driver's
door is not open, the master door
lock switches are not disabled.
Pushing the switch down on the
open passenger's door will lock all
doors. If you try to lock an open
driver's door by pushing in the lock
tab, the tabs on both front doors pop
out and the lock knobs on the rear
sliding doors slide out. Pushing in
the lock tab on the passenger's door
only locks that door.
