If you have power windows on a Crew Cab
, the
driver's door power window switch has a lockout
feature. This feature prevents all windows from
operating, except from the driver's position, when the

engaged. When the button is not engaged, the rear
power windows will operate.
Swing-Out Windows (Extended Cab)
To open a rear swing-out
window, flip the latch open
and swing the glass out.
The latch will catch when the window is fully open and
it will also hold it in the open position.

Your vehicle has one
double
-sided key for the
ignition and all door locks.
Your vehicle may also have
a key that locks and unlocks
only the center floor
console (if equipped).If you ever lose your keys, your dealer will be able to
assist you with obtaining replacements.
NOTICE:
Your vehicle has a number of new features that
can help prevent theft. But you can have a lot of
trouble getting into your vehicle if you ever lock
your key inside. You may even have to damage
your vehicle to get in. So be sure you have an
extra key.
If you ever do get locked out of your vehicle, call the
GM Roadside Assistance Center. See ªRoadside
Assistanceº in the Index. If your vehicle is equipped
with the OnStar system with an active subscription and
you lock your keys inside the vehicle, OnStar may be
able to send a command to unlock your vehicle. See
ªOnStarº in the Index for more information.

Door Locks
CAUTION:
Unlocked doors can be dangerous.
Passengers -- especially children -- can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle won't open it. You increase the
chance of being thrown out of the vehicle in
a crash if the doors aren't locked. So, wear
safety belts properly and lock the doors
whenever you drive.
Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
Outsiders can easily enter through an
unlocked door when you slow down or stop
your vehicle. Locking your doors can help
prevent this from happening.
There are several ways to lock and unlock your vehicle.
You can use the keyless entry system (if equipped).
You can also use your key.
To lock the door from
the inside, slide the
lever rearward. To unlock
the door, slide the
lever forward.
