2-2Windows
CAUTION:Leaving children in a vehicle with the windows
closed is dangerous. A child can be overcome by
the extreme heat and can suffer permanent
injuries or even death from heat stroke. Never
leave a child alone in a vehicle, especially with
the windows closed in warm or hot weather.

2-3Power Windows
The switches to operate all of the power windows are
located on the driver's door armrest. The front
passenger's door and the rear side doors also each
have an individual power window switch. Your power windows will work when the ignition has
been turned to ACCESSORY or RUN or when Retained
Accessory Power (RAP) is active. See ªRetained
Accessory Powerº in the Index.
Press the rear or front of the switch with the power
window symbol on it to lower or raise the window.
Driver's Express
- Down Window
The driver's window has an express down feature that
allows the window to be lowered without holding the
switch. Press and hold the rear of the power window
switch for one second to activate the express down
mode. The express down mode can be canceled at any
time by pressing the opposite side of the switch. To open
the window partway, lightly tap the power window
switch until the window is at the desired position.
Window Lockout Switch
The driver's door power window switch has a lockout
feature. This feature prevents the passenger's windows
from operating except from the driver's position when
the driver's door button labeled WINDOW LOCK
is engaged.

2-4Keys
CAUTION:Leaving children in a vehicle with the ignition
key is dangerous for many reasons. A child or
others could be badly injured or even killed.
They could operate the power windows or
other controls or even make the vehicle move.
Don't leave the keys in a vehicle with children.

2-5Your vehicle has one
double
- sided key for the
ignition and all door locks
as well as the spare tire
hoist lock. Your vehicle also has a key
that locks and unlocks the
console storage area only.
If you ever lose your keys, your dealer will be able to
assist you with obtaining replacements.
In an emergency contact roadside assistance.
See ªRoadside Assistanceº in the Index for
more information.
If you ever lock your keys in your vehicle, you may
be able to have your doors unlocked automatically with
the OnStar system if you have an active OnStar

subscription. For more information see ªOnStarº
in the Index.

2-6Door 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.
To unlock the door form the outside, use the keyless
entry system or the key.
To unlock the door from
the inside, slide the manual
lever forward. To lock the
door, slide the manual
lever rearward.

2-7Power Door Locks Press the raised side of the
switch, marked L on either
front door to lock all the
doors at once.
Press the recessed side of the switch marked U to unlock
all the doors at once.
On the passenger side of the
liftgate opening trim there is
a power lock switch which
can be used to lock or
unlock all of the doors. The power door locks will operate at any time without
the ignition being on.
Programmable Locks
The power door locks can be programmed to
automatically lock and unlock depending on the settings
you have chosen in the Secondary Information Center
(SIC). See ªSecondary Information Centerº in the Index
for more information.
Operating the power locks may interact with the
theft
- deterrent system. See ªContent Theft
- Deterrentº
in the Index.
Lockout Prevention 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.

2-8Child Security Locks
You will find a security lock lever on the inside edge of
each rear door. Your vehicle may be equipped with one
of the two labels shown. With this feature, you can lock the rear doors so they
cannot be opened from the inside by passengers. To use
the security locks do the following:
1. Open one of the rear doors.
2. Move the lever up to engage the security lock.
Move the lever down to disengage the security lock.
3. Close the door.
4. Do the same thing to the other rear door.
The rear doors on 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.
