Rear Door Security Locks (Crew Cab); Lockout Protection - GMC Sierra Classic 2007 Owner's Manual

Rear Door Security Locks
(Crew Cab)
With this feature, you can lock the rear side doors
so that they cannot be opened from the inside
by passengers.
To use one of the locks do the following:
1. Open one of the rear doors.
2. To engage the rear door security lock, move
the lever forward.
This feature is located
on the inside edge of
the rear doors.
3. To disengage the lock, move the
lever rearward.
4. Close the door.
5. Do the same thing to the other rear door.
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 while the security
lock is engaged, unlock the door and open the
door from the outside.

Lockout Protection

This feature protects you from locking your key in
the vehicle when the key is in the ignition and
a door is open.
If the power lock switch is pressed when a door is
open and the key is in the ignition, all of the doors
will lock and then the driver's door will unlock.
