Check your mirrors, glance over your shoulder, and
start your left lane change signal before moving out
of the right lane to pass. When you are far
enough ahead of the passed vehicle to see its front
in your inside mirror, activate your right lane
change signal and move back into the right lane.
(Remember that your right outside mirror is convex.
The vehicle you just passed may seem to be
farther away from you than it really is.)
Try not to pass more than one vehicle at a time on
two-lane roads. Reconsider before passing the
next vehicle.
Don’t overtake a slowly moving vehicle too rapidly.
Even though the brake lamps are not flashing, it
may be slowing down or starting to turn.
If you’re being passed, make it easy for the
following driver to get ahead of you. Perhaps you
can ease a little to the right.
Loss of Control
Let’s review what driving experts say about what
happens when the three control systems (brakes,
steering and acceleration) don’t have enough friction
where the tires meet the road to do what the driver
has asked.
Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not
“overdriving” those conditions. But skids are always
possible.
The three types of skids correspond to your vehicle’s
three control systems. In the braking skid, your wheels
aren’t rolling. In the steering or cornering skid, too
much speed or steering in a curve causes tires to slip
and lose cornering force. And in the acceleration
skid, too much throttle causes the driving wheels
to spin.
A cornering skid is best handled by easing your foot off
the accelerator pedal.
If you have the Enhanced Traction System, remember:
It helps to avoid only the acceleration skid. If you do
not have the Enhanced Traction System, or
if the system
is
off, then an acceleration skid is also best handled
by easing your foot
off the accelerator pedal.
If your vehicle starts to slide, ease your foot
off the
accelerator pedal and quickly steer the way you want
the vehicle to go.
If you start steering quickly enough,
your vehicle may straighten out. Always be ready
for a second skid
if it occurs.
In any emergency, don’t give up. Keep trying to steer
and constantly seek an escape route
or area of
less danger.

Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inflated to the upper limit
for cold tires. You’ll find these numbers on the Tire
Loading Information label at the rear edge of the driver’s
door or see
Loading Your Vehicle on page 4-34. Then
be sure you don’t go over the
GVW limit for your vehicle,
including the weight of the trailer tongue.
Hitches
It’s important to have the correct hitch equipment.
Crosswinds, large trucks going by and rough roads are
a few reasons why you’ll need the right hitch. Here
are some rules to follow:
The rear bumper on your vehicle is not intended for
hitches. Do not attach rental hitches or other
bumper-type hitches to it. Use only a
frame-mounted hitch that does not attach to the
bumper.
Will yo11 have to make any holes in the body nf
your vehicle when you install a trailer hitch? If
you do, then be sure to seal the holes later when
you remove the hitch. If you don’t seal them, deadly
carbon monoxide (CO) from your exhaust can get
into your vehicle. See
Engine Exhaust on
page
2-30. Dirt ana water can, too.
Safety Chains
You should always attach chains between your vehicle
and your trailer. Cross the safety chains under the
tongue of the trailer
so that the tongue will not drop to
the road
if it becomes separated from the hitch.
Instructions about safety chains may be provided by the
hitch manufacturer or by the trailer manufacturer.
Follow the manufacturer’s recommendation for attaching
safety chains and do not attach them to the bumper.
Always leave just enough slack
so you can turn
with your rig. And, never allow safety chains to drag on
the ground.
Trailer Brakes
Does your trailer have its own brakes?
Be sure to read and
follow the instructions for the trailer
brakes
so you’ll be able to install, adjust and maintain
them properly. And because you may have anti-lock
brakes, do not try to tap into your vehicle’s brake
system.
If you do, both systems won’t work well,
e!- 2! 2!!.

Inflation -- Tire Pressure
The Tire-Loading Information label, which is on the rear
edge of the driver’s door, shows the correct inflation
pressures for your tires when they’re cold. “Cold’’ means
your vehicle has been sitting for at least three hours
or driven no more than 1 mile (1.6 km).
Notice: Don’t let anyone tell you that underinflation
or overinflation is all right.
It’s not. If your tires
don’t have enough air (underinflation), you can get
the following:
Too much flexing
Too much heat
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire.
It should be at
60 psi
(420 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell
if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and
moisture.
Tire overloading
Bad wear
Bad handling
Bad fuel economy
If your tires have too much air (overinflation), you
can get the following:
Unusual wear
Bad handling
0 Rough ride
Needless damage from road hazards

When It Is Time for New Tires
One way to tell when it’s
time for new tires is to
check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of tread
remaining.
You need a new tire
if any of the following statements
are true:
You can see the indicators at three or more places
around the tire.
You can see cord or fabric showing through the
tire’s rubber.
The tread or sidewall is cracked, cut or snagged
deep enough to show cord or fabric.
The tire has a bump, bulge or split.
The tire has a puncture, cut or other damage that
can’t be repaired well because of the size or
location of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at
the Tire-Loading Information label.
The tires installed on your vehicle when it was new had
a Tire Performance Criteria Specification (TPC Spec)
number on each tire’s sidewall. When you get new tires,
get ones with that same TPC Spec number. That way
your vehicle will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service on
your vehicle.
If your tires have an all-season tread
design, the TPC number will be followed by an
“MS” (for
mud and snow).
If you ever replace your tires with those not having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.

Uniform Tire Quality Grading
Mixing tires could cause you to lose control
while driving. If you mix tires of different sizes or types (radial and bias-belted tires), the
vehicle may not handle properly, and you could have a crash. Using tires
of different
sizes may also cause damage to your vehicle.
Be sure to use the same size and type tires on
all wheels.
It's all right to drive with your
compact spare, though.
It was developed for
use on your vehicle.
I If you use bias-ply tires on your vehicle. the I
wheel rim flanges 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 your vehicle. Quality grades can
be found where applicable on the
tire sidewall between tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance. (This
applies only to vehicles sold in the United States.)
The grades are molded on the sidewalls of most
passenger car tires. The Uniform Tire Quality Grading
system does not apply to deep tread, winter-type
snow tires, space-saver or temporary use spare tires,
tires with nominal rim diameters of 10 to 12 inches
(25 to
30 cm), or to some limited-production tires.
While the tires available
on General Motors passenger
cars and light trucks may vary with respect to these
grades, they must also conform to federal safety
Performance Criteria (TPC) standards.

Used Replacement Wheels

I
Tire Chains
Putting a used wheel on your vehicle is
dangerous. You can’t know how
it’s been used
or how far
it’s been driven. It could fail
suddenly and cause a crash. If you have to replace a wheel, use a new
GM original
equipment wheel.
I
If your ve :le s FLL ;OR16 re tires, ,,n’t
use tire chains, there’s not enough clearance.
Tire chains used on a vehicle without the
proper amount of clearance can cause damage
to the brakes, suspension or other vehicle
parts. The area damaged by the tire chains
could cause you to lose control of your vehicle
and you or others may
be injured in a crash.
Use another type of traction device only
if its
manufacturer recommends
it for use on your
vehicle and tire size combination and road
conditions. Follow that manufacturer’s
instructions. To help avoid damage to your
vehicle, drive slowly, readjust or remove the device if it’s contacting your vehicle, and don’t spin your wheels.
If you do find traction devices that will
fit,
install them on the front tires.
5-60
Page 276 of 354
Notice: If your vehicle has a tire size other than
P225/50R16 size tires, use tire chains only where
legal and only when you must. Use only
SAE Class
“S” type chains that are the proper size for your
tires. Install them on the front tires and tighten them
as tightly as possible with the ends securely
fastened. Drive slowly and follow the chain manufacturer’s instructions.
If you can hear the
chains contacting your vehicle, stop and retighten
them.
If the contact continues, slow down until
it stops. Driving too fast or spinning the wheels with
chains on will damage your vehicle.
If a Tire Goes Flat
It’s unusual for a tire to “blow out” while you’re driving,
especially
if you maintain your tires properly. If air
goes out of a tire, it’s much more likely to leak out
slowly. But
if you should ever have a “blowout”, here are
a few tips about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use
ir; a skid. In any rear blowoi:, rem0t.e yoi; foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop
- well off the road if possible.
If a tire goes flat, the next part shows how to use your
iackinq equipment to chanqe a flat tire safely.
