Q:What are the different types of add-on
child restraints?
A:Add-on child restraints, which are purchased by
the vehicle’s owner, are available in four basic
types. Selection of a particular restraint should
take into consideration not only the child’s
weight, height, and age but also whether or not
the restraint will be compatible with the motor
vehicle in which it will be used.
For most basic types of child restraints, there
are many different models available. When
purchasing a child restraint, be sure it is
designed to be used in a motor vehicle. If it
is, the restraint will have a label saying that it
meets federal motor vehicle safety standards.
The restraint manufacturer’s instructions
that come with the restraint state the weight
and height limitations for a particular child
restraint. In addition, there are many kinds
of restraints available for children with
special needs.
{CAUTION:
Newborn infants need complete support,
including support for the head and neck.
This is necessary because a newborn
infant’s neck is weak and its head weighs
so much compared with the rest of its
body. In a crash, an infant in a rear-facing
seat settles into the restraint, so the crash
forces can be distributed across the
strongest part of an infant’s body, the
back and shoulders. Infants always
should be secured in appropriate infant
restraints.

In any particular crash, no one can say whether
an airbag should have inflated simply because
of the damage to a vehicle or because of what
the repair costs were. Inflation is determined
by what the vehicle hits, the angle of the impact,
and how quickly the vehicle slows down in front
or near-frontal impacts.
If the GVWR (Gross Vehicle Weight Rating) of
your vehicle is 8,500 lb (3 855 kg) or above, your
vehicle has single stage airbags. If the GVWR
is below 8,500 lb (3 855 kg), your vehicle has dual
stage airbags. You can find the GVWR on the
certification label on the rear edge of the driver’s
door. SeeLoading Your Vehicle on page 259
for more information.
Single Stage Airbags
If your vehicle has frontal airbags with single stage
deployment and your vehicle goes straight into
a wall that does not move or deform, the threshold
level is about 9 to 16 mph (14 to 26 km/h). The
threshold level can vary, however, with specific
vehicle design, so that it can be somewhat above
or below this range.
Dual Stage Airbags
If your vehicle has frontal airbags with dual stage
deployment, the restraint will adjust according
to the crash severity. Your vehicle has electronic
frontal sensors which helps the sensing system
distinguish between a moderate and a more
severe frontal impact. For moderate frontal
impacts, these airbags inflate at a level less
than full deployment. For more severe frontal
impacts, full deployment occurs. If the front of
your vehicle goes straight into a wall that does
not move or deform, the threshold level for
the reduced deployment is about 12 to 16 mph
(19 to 26 km/h), and the threshold level for
a full deployment is about 18 to 25 mph
(29 to 40 km/h). The threshold level can vary,
however, with specific vehicle design, so that it
can be somewhat above or below this range.
Vehicles with dual stage airbags also have sensors
which enable the sensing system to monitor the
position of both the driver and passenger front
seats. The seat position sensors provide
information which is used to determine if the
airbags should deploy at a reduced level or at
full deployment.
83

The passenger sensing system is designed to turn
off the right front passenger’s frontal airbag if:
•The right front passenger seat is unoccupied.
•The system determines that an infant is
present in a rear-facing infant seat.
•The system determines that a small child is
present in a forward-facing child restraint.
•The system determines that a small child is
present in a booster seat.
•A right front passenger takes his/her weight off
of the seat for a period of time.
•The right front passenger seat is occupied by
a smaller person, such as a child who has
outgrown child restraints.
•Or, if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned
off the passenger’s frontal airbag, the off indicator
on the instrument panel will light and stay lit to
remind you that the airbag is off.If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove
the child restraint from the vehicle and reinstall the
child restraint following the child restraint
manufacturer’s directions and refer toSecuring a
Child Restraint in the Right Front Seat Position
(With Passenger Sensing System)in the Index.
If, after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, check to
make sure that the vehicle’s seatback is not
pressing the child restraint into the seat cushion.
If this happens, slightly recline the vehicle’s
seatback and adjust the seat cushion if possible.
Also make sure the child restraint is not trapped
under the vehicle head restraint. If this happens,
adjust the head restraint.
If the on indicator is still lit, secure the child in
the child restraint in a rear seat position if one
is available and check with your dealer.

Torque Lock
If you are parking on a hill and you do not shift your
vehicle into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl
in the transmission. You may find it difficult to pull
the shift lever out of PARK (P). This is called torque
lock. To prevent torque lock, set the parking brake
and then shift into PARK (P) properly before you
leave the driver’s seat. To find out how, seeShifting
Into Park (P) on page 129.
When you are ready to drive, move the shift lever
out of PARK (P) before you release the parking
brake.
If torque lock does occur, you may need to have
another vehicle push yours a little uphill to
take some of the pressure from the parking pawl
in the transmission, so you can pull the shift
lever out of PARK (P).
Shifting Out of Park (P)
Your vehicle has an automatic transmission shift
lock control system. You have to fully apply
your regular brakes before you can shift from
PARK (P) when the ignition is in RUN. See
Automatic Transmission Operation on page 125.
If you cannot shift out of PARK (P), ease pressure
on the shift lever and push the shift lever all the
way up into PARK (P) as you maintain brake
application. Then, move the shift lever into
the gear you want.
If you ever hold the brake pedal down but still
cannot shift out of PARK (P), try this:
1. Turn the key to LOCK.
2. Apply and hold the brake until the end of
Step 4.
3. Shift to NEUTRAL (N).
4. Start the vehicle and then shift to the drive
gear you want.
5. Have the system fixed as soon as you can.

Drunken Driving
Death and injury associated with drinking and
driving is a national tragedy. It is the number
one contributor to the highway death toll,
claiming thousands of victims every year.
Alcohol affects four things that anyone needs to
drive a vehicle:
•Judgment
•Muscular Coordination
•Vision
•Attentiveness
Police records show that almost half of all motor
vehicle-related deaths involve alcohol. In most
cases, these deaths are the result of someone who
was drinking and driving. In recent years, more
than 16,000 annual motor vehicle-related deaths
have been associated with the use of alcohol, with
more than 300,000 people injured.Many adults — by some estimates, nearly half
the adult population — choose never to drink
alcohol, so they never drive after drinking.
For persons under 21, it is against the law in
every U.S. state to drink alcohol. There are good
medical, psychological, and developmental
reasons for these laws.
The obvious way to eliminate the leading highway
safety problem is for people never to drink
alcohol and then drive. But what if people do?
How much is “too much” if someone plans
to drive? It is a lot less than many might think.
Although it depends on each person and situation,
here is some general information on the problem.
The Blood Alcohol Concentration (BAC) of
someone who is drinking depends upon
four things:
•The amount of alcohol consumed
•The drinker’s body weight
•The amount of food that is consumed before
and during drinking
•The length of time it has taken the drinker to
consume the alcohol
229

According to the American Medical Association,
a 180 lb (82 kg) person who drinks three 12 ounce
(355 ml) bottles of beer in an hour will end up
with a BAC of about 0.06 percent. The person
would reach the same BAC by drinking three
4 ounce (120 ml) glasses of wine or three mixed
drinks if each had 1-1/2 ounces (45 ml) of
liquors like whiskey, gin, or vodka.It is the amount of alcohol that counts. For example,
if the same person drank three double martinis
(3 ounces or 90 ml of liquor each) within an hour,
the person’s BAC would be close to 0.12 percent.
A person who consumes food just before or during
drinking will have a somewhat lower BAC level.
There is a gender difference, too. Women
generally have a lower relative percentage of
body water than men. Since alcohol is carried in
body water, this means that a woman generally will
reach a higher BAC level than a man of her
same body weight will when each has the same
number of drinks.
The law in most U.S. states, and throughout
Canada, sets the legal limit at 0.08 percent.
In some other countries, the limit is even lower.
For example, it is 0.05 percent in both France
and Germany. The BAC limit for all commercial
drivers in the United States is 0.04 percent.
The BAC will be over 0.10 percent after three to
six drinks (in one hour). Of course, as we have
seen, it depends on how much alcohol is in the
drinks, and how quickly the person drinks them.

Control of a Vehicle
You have three systems that make your vehicle go
where you want it to go. They are the brakes, the
steering, and the accelerator. All three systems
have to do their work at the places where the tires
meet the road.
Sometimes, as when you are driving on snow or
ice, it is easy to ask more of those control systems
than the tires and road can provide. That means
you can lose control of your vehicle.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 286.
Braking
SeeBrake System Warning Light on page 175.
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake
pedal. That is perception time. Then you have to
bring up your foot and do it. That is reaction time.
Average reaction time is about three-fourths of a
second. But that is only an average. It might be less
with one driver and as long as two or three seconds
or more with another. Age, physical condition,
alertness, coordination, and eyesight all play a part.
So do alcohol, drugs, and frustration. But even in
three-fourths of a second, a vehicle moving at
60 mph (100 km/h) travels 66 feet (20 m). That
could be a lot of distance in an emergency, so
keeping enough space between your vehicle and
others is important.
And, of course, actual stopping distances vary
greatly with the surface of the road, whether it is
pavement or gravel; the condition of the road,
whether it is wet, dry, or icy; tire tread; the
condition of the brakes; the weight of the vehicle;
and the amount of brake force applied.
232

Loading Your Vehicle
It is very important to know how much weight
your vehicle can carry. This weight is called the
vehicle capacity weight and includes the weight of
all occupants, cargo, and all nonfactory-installed
options. Two labels on your vehicle show how
much weight it was designed to carry, the Tire
and Loading Information label and the
Certification/Tire label.
{CAUTION:
Do not load your vehicle any heavier than
the Gross Vehicle Weight Rating (GVWR),
or either the maximum front or rear Gross
Axle Weight Rating (GAWR). If you do,
parts on your vehicle can break, and it
can change the way your vehicle handles.
These could cause you to lose control
and crash. Also, overloading can shorten
the life of your vehicle.
Tire and Loading Information Label
A vehicle specific Tire and Loading Information
label is attached to the center pillar (B-pillar).
With the driver’s door open, you will find the label
attached below the door lock post (striker).
The tire and loading information label shows the
number of occupant seating positions (A), and the
maximum vehicle capacity weight (B) in kilograms
and pounds.
