armrest on each of the side doors. With power windows,
the switches operate the windows when the ignition is

-down feature. Lightly tap the switch
to open the window slightly. The express
-down feature
can be interrupted at any time by pressing the top of
the switch.

This vehicle has one
double
-sided key for the
ignition and door locks. It
will fit with either side up.
When a new vehicle is delivered, the dealer provides
the owner with a pair of identical keys and a key
code number.
The key code number tells your dealer or a qualified
locksmith how to make extra keys. Keep this number in
a safe place. If you lose your keys, you'll be able to have
new ones made easily using this number. Your selling
dealer should also have this number.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.

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 remote keyless entry system.
You can use your key to unlock your door from
the outside.
You can lock or unlock the door from the inside by
sliding the manual lever forward or rearward. When the
door is unlocked, you can see a red area on the lever.
The manual lever on each rear door works only that
door's lock.
