Driving Your Vehicle
Defensive Driving
Defensive driving means “always
expect the unexpected.” The
rst step in driving defensively is to
wear your safety belt, seeSafety
Belts on page 1-5.
{CAUTION
Assume that other road users
(pedestrians, bicyclists, and other
drivers) are going to be careless
and make mistakes. Anticipate
what they might do and be ready.
In addition:
Allow enough following
distance between you and
the driver in front of you.
Focus on the task of driving.
Driver distraction can cause
collisions resulting in injury or
possible death. These simple
defensive driving techniques could
save your life.
Drunk Driving
{CAUTION
Drinking and then driving is very
dangerous. Your reexes,
perceptions, attentiveness, and
judgment can be affected by even
a small amount of alcohol. You
can have a serious — or even
fatal — collision if you drive after
drinking. Do not drink and drive or
ride with a driver who has been
drinking. Ride home in a cab; or if
you are with a group, designate a
driver who will not drink.
Death and injury associated with
drinking and driving is a global
tragedy.
8-16 Driving and Operating

Steering
Power Steering
If you lose power steering assist
because the engine stops or the
system is not functioning, you can
steer but it will take much more effort.
Steering Tips
It is important to take curves at a
reasonable speed.
Traction in a curve depends on the
condition of the tires and the
road surface, the angle at which the
curve is banked, and your speed.
While in a curve, speed is the
one factor you can control.
If you need to reduce speed, do it
before you enter the curve, while the
front wheels are straight ahead.
Try to adjust the speed so you can
drive through the curve. Maintain
a reasonable, steady speed. Wait to
accelerate until you are out of the
curve, and then accelerate
gently into the straightaway.
Steering in Emergencies
There are times when steering can
be more effective than braking.
For example, you come over a hill
and nd a truck stopped in your
lane, or a car suddenly pulls
out from nowhere, or a child darts
out from between parked cars
and stops right in front of you.
You can avoid these problems by
braking — if you can stop in
time. But sometimes you cannot;
there is not room. That is the
time for evasive action — steering
around the problem.
Your vehicle can perform very well
in emergencies like these. First
apply the brakes. SeeBraking on
page 8-17. It is better to remove as
much speed as you can from a
possible collision. Then steer around
the problem, to the left or right
depending on the space available.An emergency like this requires
close attention and a quick decision.
If you are holding the steering wheel
at the recommended 9 and 3 o’clock
positions, you can turn it a full
180 degrees very quickly without
removing either hand. But you have
to act fast, steer quickly, and just as
quickly straighten the wheel once
you have avoided the object.
The fact that such emergency
situations are always possible is a
good reason to practice defensive
driving at all times and wear
safety belts properly.

Tire Size
The following illustration shows
an example of a typical
passenger vehicle tire size.
(A) Passenger (P-Metric) Tire
:The United States version of
a metric tire sizing system.
The letter P as the rst character
in the tire size means a
passenger vehicle tire
engineered to standards set
by the U.S. Tire and Rim
Association.(B) Tire Width
:The three-digit
number indicates the tire
section width in millimeters
from sidewall to sidewall.
(C) Aspect Ratio
:A two-digit
number that indicates the tire
height-to-width measurements.
For example, if the tire size
aspect ratio is 60, as shown in
item C of the illustration, it would
mean that the tire’s sidewall is
60 percent as high as it is wide.
(D) Construction Code
:A letter code is used to indicate
the type of ply construction in
the tire. The letter R means
radial ply construction; the
letter D means diagonal or bias
ply construction; and the
letter B means belted-bias ply
construction.(E) Rim Diameter
:Diameter of
the wheel in inches.
(F) Service Description
:These characters represent the
load range and speed rating
of the tire. The load index
represents the load carry
capacity a tire is certied to
carry. The load index can range
from 1 to 279. The speed
rating is the maximum speed
a tire is certied to carry
a load. Speed ratings range
fromAtoZ.

Tire Terminology and
Denitions
Air Pressure:The amount of
air inside the tire pressing
outward on each square inch
of the tire. Air pressure is
expressed in pounds per square
inch (psi) or kilopascal (kPa).
Accessory Weight
:This
means the combined weight
of optional accessories.
Some examples of optional
accessories are, automatic
transmission, power steering,
power brakes, power windows,
power seats, and air
conditioning.
Aspect Ratio
:The relationship
of a tire’s height to its width.Belt
:A rubber coated layer of
cords that is located between the
plies and the tread. Cords may
be made from steel or other
reinforcing materials.
Bead
:The tire bead contains
steel wires wrapped by steel
cords that hold the tire onto
the rim.
Bias Ply Tire
:A pneumatic tire
in which the plies are laid at
alternate angles less than
90 degrees to the centerline of
the tread.
Cold Tire Pressure
:The
amount of air pressure in a tire,
measured in pounds per square
inch (psi) or kilopascals (kPa)
before a tire has built up heat
from driving. SeeInflation - Tire
Pressure on page 9-49.Curb Weight
:The weight of a
motor vehicle with standard
and optional equipment including
the maximum capacity of fuel,
oil, and coolant, but without
passengers and cargo.
DOT Markings
:A code molded
into the sidewall of a tire
signifying that the tire is in
compliance with the U.S.
Department of Transportation
(DOT) motor vehicle safety
standards. The DOT code
includes the Tire Identication
Number (TIN), an alphanumeric
designator which can also
identify the tire manufacturer,
production plant, brand, and date
of production.

9-46 Vehicle Service and Care

GM’s exclusive TPC Spec system
considers over a dozen critical
specications that impact the overall
performance of your vehicle,
including brake system performance,
ride and handling, traction control,
and tire pressure monitoring
performance. GM’s TPC Spec
number is molded onto the tire’s
sidewall near the tire size. If the tires
have an all-season tread design,
the TPC Spec number will be
followed by an MS for mud and
snow. SeeTire Sidewall Labeling on
page 9-42for additional information.
GM recommends replacing tires
in sets of four. This is because
uniform tread depth on all tires will
help keep your vehicle performing
most like it did when the tires
were new. Replacing less than a full
set of tires can affect the braking
and handling performance of
your vehicle. SeeTire Inspection
and Rotation on page 9-57for
information on proper tire rotation.{CAUTION
Mixing tires could cause you
to lose control while driving. If
you mix tires of different sizes,
brands, or types (radial and
bias-belted tires), the vehicle
may not handle properly, and
you could have a crash. Using
tires of different sizes, brands,
or types may also cause
damage to the vehicle. Be
sure to use the correct size,
brand, and type of tires on all
wheels. It is all right to drive
with the compact spare
temporarily, as it was
developed for use on the
vehicle. SeeCompact Spare
Tire on page 9-83.{CAUTION
If you use bias-ply tires on the
vehicle, the wheel rim anges
could develop cracks after
many miles of driving. A tire
and/or wheel could fail
suddenly, causing a crash.
Use only radial-ply tires with
the wheels on the vehicle.
If you must replace your vehicle’s
tires with those that do not have
a TPC Spec number, make
sure they are the same size, load
range, speed rating, and
construction type (radial and
bias-belted tires) as your vehicle’s
original tires.
9-60 Vehicle Service and Care

When You Are Ready to Leave
After Parking on a Hill
1. Apply your regular brakes and
hold the pedal down while you:
Start your engine.
Shift into a gear.
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is
clear of the chocks.
4. Stop and have someone pick up
and store the chocks.
Maintenance When Trailer
Towing
Your vehicle will need service more
often when you’re pulling a trailer.
See the Maintenance Schedule for
more on this. Things that are
especially important in trailer
operation are automatic transmission
uid (don’t overll), engine oil, drivebelt, cooling system and brake
system. Each of these is covered in
this manual, and the Index will help
you nd them quickly. If you’re
trailering, it’s a good idea to review
this information before you start
your trip.
Check periodically to see that all
hitch nuts and bolts are tight.
Engine Cooling When Trailer
Towing
Your cooling system may
temporarily overheat during severe
operating conditions. SeeEngine
Overheating on page 9-20.
Appearance Care
Interior Cleaning
Your vehicle’s interior will continue to
look its best if it is cleaned often.
Although not always visible, dust and
dirt can accumulate on your
upholstery. Dirt can damage carpet,
fabric, leather, and plastic surfaces.
Regular vacuuming is recommended
to remove particles from the
upholstery. It is important to keep
your upholstery from becoming and
remaining heavily soiled. Soils
should be removed as quickly as
possible. Your vehicle’s interior may
experience extremes of heat that
could cause stains to set rapidly.
Lighter colored interiors may require
more frequent cleaning. Use care
because newspapers and garments
that transfer color to your home
furnishings may also transfer color
to your vehicle’s interior.
