Q:
A:
If I’m a good driver, and I never drive far from
home, why should
I wear safety belts?
You may be an excellent driver, but
if you’re in an
accident
- even one that isn’t your fault - you and
your passengers can be hurt. Being a good
driver doesn’t protect you from things beyond your
control, such as bad drivers.
Most accidents occur within
25 miles (40 km) of
home. And the greatest number of serious injuries
and deaths occur at speeds of less than
40 mph
(65 km/h).
Safety belts are for everyone.
How to Wear Safety Belts Properly
This part is only for people of adult size.
Be aware that there are special things to know about
safety belts and children. And there are different
rules for smaller children and babies. If a child will be
riding in your vehicle, see
Older Children on page 1-30
or lnfants and Young Children on page 1-32. Follow
those rules for everyone’s protection.
First, you’ll want to know which restraint systems your
vehicle has.
Driver Position
This part describes the driver’s restraint system.
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here’s how to wear it
properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To see
how, see “Seats’’ in the Index.
We’ll start with the driver position.

Your vehicle has one
double-sided key for the
ignition and all door
locks as well as the spare
tire hoist lock,
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 features that
can help prevent theft. You can have a lot
of
trouble getting into your vehicle if you ever lock
your keys inside. You may even have to damage
your vehicle to get in.
So be sure you have
spare keys.
If you ever do get locked out of your vehicle, call the
GM Roadside Assistance Center. See Roadside
Assistance Program
on page 7-5. 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
OnStap System on page 2-33
for more information.

At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or
if you have to stand closer
to your vehicle for the transmitter to work, try this:
Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
Check the location. Other vehicles or objects may be
blocking the signal. Take a few steps to the left or
right, hold the transmitter higher, and try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page
2-4.

Operation
You can lock and unlock your doors from about 3 feet
(1 m) up to 100 feet (30 m) away using the remote
keyless entry transmitter supplied with your vehicle. UNLOCK:
Pressing this button once will unlock the
driver’s door. The interior lamps will come on. Pressing

doors. You can choose different feedback options
for each press of the LOCK button. See
DlC Operation
and Displays on page
3-43 for more information.
Operating the keyless entry transmitter may interact with
the theft-deterrent system. See
Content Theft-Deterrent

page
3-43 for more information.
Remote Alarm
When the horn symbol on the keyless entry transmitter
is pressed, the horn will sound and the headlamps

Door Locks

To lock and unlock your vehicle, do one of the following:
You can use the keyless entry system,
use your key, or
Unlocked doors can be dangerous.
e
e
e 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.
e lock the door from the
inside by sliding the
manual lock lever
rearward.
To unlock the
door, slide the manual
lock lever forward.

Power Door Locks
If your vehicle is equipped
with power door locks,
press the raised side of the
switch, with the lock
symbol, on either front
door to lock all the doors
at once. Press the recessed side
of the switch with the unlock
symbol, to unlock all the doors at once.
The power door locks will operate at any time even
when the ignition is
off.
Operating the power locks may interact with the
theft-deterrent system (if equipped). See
Content
Theft-Deterrent on page

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make
it
impossible to steal. However, there are ways you
can help.
Content Theft-Deterrent
Your vehicle is equipped with a content theft-deterrent
alarm system.
With this system, the
security light on the cluster
will flash
as you open
the door
(if your ignition is
off), to let you know
that you are activating the
system. This
message reminds you to activate the theft-deterrent
system. Here’s how to do it:
1. Open the door.
2. Lock the door with the power door lock switch or
the remote keyless entry transmitter. The security light should come on and flash.
If you are using the
remote keyless entry transmitter, the door does
not need to be open.
3. Close all of the doors. The light will stop flashing and
stay solid.The security light should go
off after
approximately
30 seconds. The alarm is not armed
until the security light goes
off. If the delayed locking
feature is active, the alarm will not activate until all
doors are closed and the security light goes
off.
Once the system is armed, if a door is opened without
the key or the remote keyless entry transmitter, the
alarm will go
off. Depending on how you have
programmed the alarm in the secondary information
center, the horn may sound, the headlamps may flash
or both the headlamps and the horn will activate.
Remember, the theft-deterrent system won’t activate
if
you lock the doors with a key or use the manual
door lock. It activates only
if you use a power door lock
switch with the door open, or with the remote keyless
entry transmitter. You should also remember that
you can start your vehicle with the correct ignition key
if
the alarm has been set off.

Here’s how to avoid setting off the alarm by accident:
If you don’t want to activate the theft-deterrent
system, the vehicle should be locked with the door
key after the doors are closed.
Always unlock a door with a key, or use the remote
keyless entry transmitter. Unlocking a door any
other way will set
off the alarm if the system
has been armed.
If you set off the alarm by accident, unlock any door
with the key. You can also turn
off the alarm by pressing
UNLOCK on the remote keyless entry transmitter or
by placing the key in the ignition and turning it to
START.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver’s window
and open the driver’s door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3. Get out of the vehicle, close the door and wait for
the security message
to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set
off the alarm. If the
alarm does not sound and the headlamps do not
flash, you may have the feature turned
off. See DIC
Operation and Displays on page 3-43 for more
information.
Passlock@
Your vehicle is equipped with the
Passlock@ theft-deterrent system.
Passlock@ is a passive theft-deterrent system.
Passlock@ enables fuel
if the ignition lock cylinder is
turned with a valid key.
If a correct key is not used or the
ignition lock cylinder is tampered with, fuel is disabled.
If the engine stalls and the security light flashes,
wait until the light stops flashing before trying to restart
the engine. Remember
to release the key from
START as soon as the engine starts.
If the engine is running and the security light comes on,
you will be able
to restart the engine if you turn the
engine
off. However, your Passlock@ system is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock@ at this
time. You may also want to check the fuse (see
Fuses and Circuit Breakers on page 5-95.) See your
dealer for service.
In an emergency, call the GM Roadside Assistance
Center. See
Roadside Assistance Program on page 7-5
under Customer Assistance Information.
