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.

The passenger sensing system is designed to turn
off the right front passenger’s frontal airbag and
seat-mounted side impact airbag (if equipped) 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 right front passenger’s frontal airbag
and seat-mounted side impact airbag (if equipped),
the off symbol near the clock will light and stay
lit to remind you that the airbag or airbags are off.
SeePassenger Airbag Status Indicator on
page 165.
If a child restraint has been installed and the off
symbol is not 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
on page 62.

If a person of adult-size is sitting in the right front
passenger’s seat, but the off symbol is lit, it
could be because that person is not sitting properly
in the seat. If this happens do one of the
following:
•Turn the vehicle off and ask the person to
place the seatback in the fully upright
position, then sit upright in the seat, centered
on the seat cushion, with the person’s legs
comfortably extended. Restart the vehicle and
have the person remain in this position for
about three minutes. This will allow the system
to detect that person and then enable the
passenger’s airbag or airbags.
•Take the right front passenger’s weight off of
the seat for more than three seconds, place the
seatback in the fully upright position, and then
sit upright in the seat, centered on the seat
cushion, with the person’s legs comfortably
extended. Have the person remain in this
position for about three minutes. This will allow
the system to detect that person and then
enable the passenger’s airbag or airbags.

Torque Lock (Automatic Transaxle)
If you are parking on a hill and you do not shift
your transaxle into PARK (P) properly, the
weight of the vehicle may put too much force on
the parking pawl in the transaxle. 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) (Automatic Transaxle) on page 117.
When you are ready to drive, move the shift
lever out of PARK (P)beforeyou 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 transaxle, so you can pull the shift lever
out of PARK (P).
Shifting Out of Park (P)
(Automatic Transaxle)
An automatic transaxle vehicle has an automatic
transaxle shift lock control system which locks
the shift lever in PARK (P) when the ignition is in
LOCK. You have to fully apply your regular
brakes before you can shift from PARK (P) when
the ignition is turned to ON. SeeAutomatic
Transaxle Operation on page 110.
If you cannot shift out of PARK (P) while holding
the brake pedal down, try this:
1. Set the parking brake.
2. Turn the ignition off and remove the key.
3. Pry off the cover over the shift-lock release
slot using a small, flat object. The shift-lock
release slot is located at the top of the
shift lever.

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
207

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
Modifications on page 249.
Braking
SeeBrake System Warning Light on page 168.
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.

Rocking Your Vehicle to Get It Out
First, turn the steering wheel left and right.
That will clear the area around the front wheels.
Then shift back and forth between REVERSE (R)
and a forward gear, or with a manual transaxle,
between FIRST (1) or SECOND (2) and
REVERSE (R), spinning the wheels as little as
possible. Release the accelerator pedal while you
shift, and press lightly on the accelerator pedal
when the transaxle is in gear. By slowly spinning
the wheels in the forward and reverse directions,
you will cause a rocking motion that may free your
vehicle. If that does not get your vehicle out
after a few tries, it may need to be towed out.
If your vehicle does need to be towed out,
seeTowing Your Vehicle on page 241.
Loading Your Vehicle
It is very important to know how much weight your
vehicle can carry. This weight is called the
Maximum Load weight and includes the weight of
all occupants, cargo, and all nonfactory-installed
options. Two labels on your vehicle show how
much weight it may properly carry; the Tire and
Loading Information label and the Certification
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.
