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.
0 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.
In any emergency, don’t give up. Keep trying to steer
and constantly seek an escape route or area of
less danger.
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 acceleratlon
skid, too much throttle causes the driving wheels
to spin.

Driving at Night
I
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to be
impaired
- by alcohol or drugs, with night vision
problems, or by fatigue.
Here are some tips on night driving.
e
e
e
e
Drive defensively.
Don’t drink and drive.
Adjust your inside rearview mirror
to reduce the
glare from headlamps behind you.
Since you can’t see as well, you may need to slow
down and keep more space between you and other vehicles.
Slow down, especially on higher speed roads. Your
headlamps can light up only
so much road ahead.
In remote areas, watch for animals.
If you’re tired, pull
off the road in a safe place
and rest.

Driving Through Flowing Water
Flowing or rushing water creates strong
forces.
If you try to drive through flowing
water, as you might at a low water crossing,
your vehicle can be carried away.
As little as
six inches of flowing water can carry away a
smaller vehicle. If this happens, you and other
vehicle occupants could drown. Don’t ignore police warning signs, and otherwise be very
cautious about trying to drive through flowing
water.

Some Other Rainy Weather Tips
0 Besides slowing down, allow some extra following
distance. And be especiaiiy careiui wnen
you
pass another vehicle. Allow yourself more clear
room ahead, and be prepared
to have your
view restricted by road spray.
0 Have good tires with proper tread depth. See Tires
on page 5-53.
City Driving
One of the biggest problems with city streets is the
amount of traffic on them. You’ll want to watch out
for
what the other drivers are doing and pay attention
to traffic signals.

You can run the engine to keep warm, but be careful.
Snow can trap exhaust gases under your
vehicle. This can cause deadly
CO (carbon
monoxide) gas to get inside.
CO could
overcome you and kill you. You can’t see
it or
smell
it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking your exhaust pipe. And check around
again from time to time to be sure snow
doesn’t collect there.
Open a window just a little on the side of the
vehicle that’s away from the wind. This will help keep
CO out. Run your engine only
as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That
is, push the accelerator
slightly. This uses less fuel for the heat that you get and
it keeps the battery charged. You will need a
well-charged battery
to restart the vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run for a while.
Then, shut the engine
off and close the window almost
all the way
to preserve the heat. Start the engine
again and repeat this only when you feel really
uncomfortable from the cold. But do it as little as
possible. Preserve the fuel as long as you can.
To help
keep warm, you can get out of the vehicle and do
some fairly vigorous exercises every half hour or
so until
help comes.

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 have anti-lock brakes,
do not
try to tap into your vehicle’s brake system. If
you do, both systems won’t work well, or at all.
Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the trailer.
And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand
to be
sure the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer
brakes are still working.

When You Are Ready to Leave After
Parking on
a Hill
1. Apply your regular brakes and hold the pedal down
while you:
0 start your engine,
0 shift into a gear, and
0 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 transaxle fluid (don’t overfill), engine
oil, drive belt, cooling system and brake system.
Each of these
is covered in this manual, and the
Index will help you find 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. See
Engine Overheating on
page 5-26.

Automatic Transaxle Fluid
It is not necessary to check the transaxle fluid level. A
transaxle fluid leak is the only reason for fluid loss.
If a leak occurs, take the vehicle to the dealership
service department and have it repaired as soon as
possible. You may also have your fluid level checked by
your dealer or service center when you have your oil
changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside temperature
In hilly or mountainous terrain.

service. If
you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
Notice: We recommend you use only fluid labeled
DEXRON@-Ill, because fluid with that label
is
made especially for your automatic transaxle.
Damage caused by fluid other than DEXRON@-Ill is
not covered
by your new vehicle warranty.
Manual Transaxle Fluid
It is not necessary to check the transaxle fluid level. A
transaxle fluid leak is the only reason for fluid loss.
If a leak occurs, take the vehicle to the dealership
service department and have it repaired as soon as
possible. You may also have your fluid level checked by
your dealer or service center when you have your oil
changed. See
Part D: Recommended Fluids and
Lubricants
on page 6-15 for the proper fluid to use.

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
wheel rim flanges could develop cracks after
I
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.

Uniform Tire Quality Grading
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
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
5-57
Page 281 of 354
Treadwear Temperature - A, B, C
The
treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course.
For example, a tire graded
150 would wear one and
a half
(1.5) times as well on the government course as
a tire graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart significantly from the norm
due
to variations in driving habits, service practices and
differences in road characteristics and climate.
Traction - AA, A, B, C
The traction grades, from highest to lowest, are AA, A,
B, and C. Those grades represent the tire’s ability
to stop on wet pavement as measured under controlled
conditions on specified government test surfaces of
asphalt and concrete.
A tire marked C may have poor
traction performance. Warning: The traction grade
assigned to this tire is based on straight-ahead braking
traction tests, and does not include acceleration,
cornering, hydroplaning, or peak traction characteristics. The
temperature grades are
A (the highest), B, and C,
representing the tire’s resistance to the generation
of heat and its ability
to dissipate heat when tested
under controlled conditions on a specified indoor
laboratory test wheel. Sustained high temperature can
cause the material of the tire
to degenerate and
reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade
C corresponds to a
level of performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels of
performance
on the laboratory test wheel than the
minimum required by law.
Warning: The temperature grade for this tire is
established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.

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
in a skid. In any rear blowout, remove your 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
jacking equipment
to change a flat tire safely.
