After Off-Road Driving
Remove any biush or debris that has collected on the underbody, chassis or
under the hood. These accumulations
can be a fire hazard.
After operation
in mud or sand, have the brake linings cleaned and checked.
These substances
can cause glazing and uneven braking. Check the body
structure, steering, suspension, wheels, tires, and
exhaust system for
damage. Also, check the fuel lines and cooling system for any leakage.
Your vehicle will require more frequent service due to off-road use. Refer
to the Maintenance Schedule
for additional information.
Driving at Night
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.

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.

Night Vision
No one can see as well at night as in the daytime. But as we get older these
differences increase. A 50-year-old driver may require at least twice as
much light
to see the same thing at night as a 20-year-old.
What you do
in the daytime can also affect your night vision. For example,
if you spend the day
in bright sunshine you are wise to wear sunglasses.
Your eyes will have less trouble adjusting
to night. But if you’re driving,
don’t wear sunglasses at night. They may cut down
on glare from
headlamps, but
they also make a lot of things invisible.
You can be temporarily blinded by approaching lights. It can take a second
or two, or even several seconds, for your eyes to readjust to the dark. When
you are faced with severe glare (as from a driver who doesn’t lower the high
beams,
or a vehicle with misaimed headlamps), slow down a little. Avoid
staring directly into the approaching lights.
Keep your windshield and all the glass on your vehicle clean
- inside and
out. Glare at night is made much worse by dirt on the glass. Even the inside
of the glass can build up a film caused by dust. Dirty glass makes lights
dazzle and flash more than
clean glass would, making the pupils of your
eyes contract repeatedly.
Remember that your headlamps light
up far less of a roadway when you are
in
a turn or curve. Keep your eyes moving; that way, it’s easier to pick out
dimly lighted objects. Just as your headlamps should be checked regularly
for proper aim,
so should your eyes be examined regularly. Some drivers
suffer from night blindness
- the inability to see in dim light - and aren’t
even aware
of it.
Driving in the Rain
Rain and wet roads can mean driving trouble. On a wet road you can’t stop,
accelerate or turn as well because your tire-to-road traction isn’t as good as
on dry roads. And,
if your tires don’t have much tread left, you’ll get even

less traction. It's always wise to go slower and be cautious if rain starts to
fall while you are driving. The surface may get wet suddenly when your
reflexes are tuned for driving
on dry pavement.
The heavier the rain, the harder it is to see. Even if your windshield wiper
blades are in good shape, a heavy rain can make it harder to see road signs
and traffic signals, pavement markings, the edge of the road, and even
people walking.
It's wise to keep your wiping equipment in good shape and keep your
windshield washer tank filled. Replace your windshield wiper inserts when
they show signs of streaking or missing areas on the windshield, or when
strips of rubber start to separate from the inserts.
Driving too fast through large water puddles or even going through some
car washes can cause problems, too. The water may affect your brakes. Try
to avoid puddles. But if you can't, try to slow down before you hit them.
Hydroplaning
Hydroplaning is dangerous. So much water can build up under your tires
that they can actually ride on the water. This can happen if the road is wet
enough and you're going fast enough. When your vehicle is hydroplaning, it
has little or no contact with the road.

Hydroplaning doesn’t happen often. But it can if your tires haven’t much
tread or if the pressure in one or more is low. It can happen if a lot of water
is standing on the road. If you can see reflections from trees, telephone
poles, or other vehicles, and raindrops “dimple” the water’s surface, there
could be hydroplaning.
Hydroplaning usually happens at higher speeds. There just isn’t
a hard and
fast rule about hydroplaning. The best advice is
to slow down when it is
raining.

especially careful when
you pass another vehicle. Allow yourself more
clear room ahead, and be prepared to have your view restricted by road
spray.
Have good tires with proper tread depth. (See “Tires” in the Index.)
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.
Here are ways to increase your safety in city driving:
Know the best way to get to where you are going. Get a city map and
plan your trip into an unknown part
of the city just as you would for a
cross-country trip.

When you want to leave the freeway, move to the proper lane well in
advance. If you miss your exit do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp
can be curved, sometimes quite sharply.
The exit speed
is usually posted.
Reduce your speed according to your speedometer, not to your sense of
motion. After driving for any distance at higher speeds, you may tend
to
think you are going slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you must start when you’re
not fresh
- such as after a day’s work - don’t plan to make too many
miles that first part of the journey. Wear comfortable clothing and
shoes you
can easily drive in.
Is your vehicle ready for a long trip? If you keep it serviced and maintained,
it’s ready to go. If
it needs service, have it done before starting out. Of
course, you’ll find experienced and able service experts in
GM dealers all
across
North America. They’ll be ready and willing to help if you need it.
Here are some things you can check before
a trip:
0 Windshield Washer Fluid: Is the reservoir full? Are all windows clean
inside and outside?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked all levels?
Lamps: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe, trouble-free trip. Is the tread
good enough for long-distance driving? Are the tires all inflated to the
recommended pressure?
Should you delay your trip a short time to avoid a major
storm system?
Weather Forecasts: What’s the weather outlook along your route?
Maps: Do you have up-to-date maps?
Highway Hypnosis
Is there actually such a condition as “highway hypnosis”? Or is it just plain
falling asleep
at the wheel? Call it highway hypnosis, lack of awareness, or
whatever.
ProCarManuals.com

There is something about an easy stretch of road with the same scenery,
along with the hum
of the tires on the road, the drone of the engine, and the
rush of the wind against the vehicle that can make you sleepy. Don’t let it
happen to
you! If it does, your vehicle can leave the road in less than a
second,
and you could crash and be injured.
What can you do about highway hypnosis? First, be aware that it can
happen.
Then here are some tips:
0 Make sure your vehicle is well ventilated, with a comfortably cool
interior.
Keep your eyes moving. Scan the road ahead and to the sides. Check
your mirrors and your instruments frequently.
and take a nap, get some exercise, or both. For safety, treat drowsiness
If you get sleepy, pull off the road into a rest, service, or parking area
on the highway
as an emergency.
Hill and Mountain Roads
Driving on steep hills or mountains is different from driving in flat or
rolling terrain.
If you drive regularly in steep country, or if you’re planning to visit there,
here are some tips that can make your trips safer and more enjoyable. (See
“Off-Road Driving”
in the Index for information about driving off-road.)

Keep your vehicle in good shape. Check all fluid levels and also the
brakes, tires, cooling system and transmission. These parts can work
hard on mountain roads.
Know
how to go down hills. The most important thing to know is this:
let your engine
do some of the slowing down. Shift to a lower gear
when
you go down a steep or long hill.

Winter Driving
Here are some tips for winter driving:
0 Have your vehicle in good shape for winter. Be sure your engine
coolant
mix is correct.
0 You may want to put winter emergency supplies in your vehicle.
Include an ice scraper, a small brush
or broom, a supply of windshield
washer fluid, a rag, some winter outer clothing, a small shovel, a flashlight,
a red cloth, and a couple of reflective warning triangles. And,
if you will be
driving under severe conditions, include a small bag of sand, a piece of old
carpet or a couple
of burlap bags to help provide traction. Be sure you
properly secure these items
in your vehicle.
Driving on Snow or Ice
Most of the time, those places where your tires meet the road probably have
good traction.
However,
if there is snow or ice between your tires and the road, you can
have a very slippery situation. You’ll have a lot less traction or “grip” and
will need to be very careful.
4-31
ProCarManuals.com

What’s the worst time for this? “Wet ice.” Very cold snow or ice can be
slick and hard to drive on. But wet ice can be even more trouble because it
may offer the least traction
of all. You can get “wet ice” when it’s about
freezing
(32 OF; 0” C) and freezing rain begins to fall. Try to avoid driving
on wet ice until salt and sand crews can get there.
Whatever the condition
- smooth ice, packed, blowing or loose snow -
drive with caution.
Accelerate gently. Try not to break the fragile traction.
If you accelerate too
fast, the drive wheels will spin and polish the surface under the tires
even
more.
Your anti-lock brakes improve your ability to make a hard stop
on a
slippery road. Even though you have an anti-lock braking system, you’ll
want to begin stopping sooner than
you would on dry pavement. See
“Anti-Lock” in the Index.
Allow greater following distance on any slippery road.
Watch for slippery spots. The road might be fine until you hit a spot
that’s covered with ice. On an otherwise clear road, ice patches may
appear in shaded areas where the sun can’t reach: around clumps of
trees, behind buildings, or under bridges. Sometimes
the surface of a
curve or
an overpass may remain icy when the surrounding roads are
clear.
If you see a patch of ice ahead of you, brake before you are on it.
Try not to brake while you’re actually on the ice, and avoid sudden
steering maneuvers.
