2004 Pontiac Grand Prix Owner ManualM

Q:If I'm a good driver, and I never drive far from
home, why should I wear safety belts?
A: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 1-29orInfants 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.
We'll start with the driver position.
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 ªSeatsº in the Index.
1-15

The side impact air bag for the right front passenger
and the person seated directly behind that passenger is
in the ceiling above the side windows.
{CAUTION:
If something is between an occupant and an
air bag, the bag might not in¯ate properly or it
might force the object into that person causing
severe injury or even death. The path of an
in¯ating air bag must be kept clear. Don't put
anything between an occupant and an air bag,
and don't attach or put anything on the
steering wheel hub or on or near any other air
bag covering. And, because your vehicle has
side impact air bags, never secure anything to
the roof of your vehicle by routing the rope or
tiedown through any door or window opening.
If you do, the path of an in¯ating side impact
air bag will be blocked. The path of an in¯ating
air bag must be kept clear.

your vehicle to get in. So be sure you have
spare keys.
If your vehicle is equipped with the OnStar
žsystem with

transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the

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
