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.
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 flzan u secord, 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:
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.
If you get sleepy, pull off the road into a rest, service
or parking area and take a nap, get some exercise, or
both. For safety, treat drowsiness
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 re.gularly in steep country, or if you’re
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.

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.
A CAUTION:
If you don’t shift down, your brakes could get so
hot that they wouldn’t work well. You would then
have poor braking or even none going down a hill
You could crash. Shift down to let your engine
assist your brakes on
a steep downhill slope. Coasting
downhill in
NEUTRAL (N) or with the
ignition
off is dangerous. Your brakes will have to
do all the work
of slowing down. They could get so
hot that they wouldn’t work well. You would then
have poor braking or even none going down a hill.
You could crash. Always have your engine running
and your vehicle in gear when you go downhill.

Know how tb go uphill. You may want to shift down
to a lower gear. The lower gears help cool your engine
and transmission, and you can climb the
hill better.
Stay
in your own lane when driving on two-lane
roads
in hills or mountains. Don’t swing wide or
cut across the center of
the road. Drive at speeds
that let
YOLI stay in your own lane.
As you go over the top of a hill, be alert. There could be
something
in your lane, like a stalled car or an accident.
You may see highway signs on mountains that warn of
special problems. Examples are long grades, passing or
no-passing zones,
a falling rocks area or winding
roads. Be ale1-f to these and take appropriate action.

Winter Driving
Here are some tips for winter driving:
Have your vehicle in good shape for winter.
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. 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 rnay offer the
least traction
of all. You can get wet ice when it‘s about
freezing
(32°F; OOC) 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 vehicle’s stability
when you 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.
0 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.
If You’re Caught in .a Blizzard
If you are stopped by heavy snow, you could be in a
serious situation. You should probably stay with your
vehicle unless you know for sure that you
are near help
and you can hike through the snow. Here
are some
things to do to summon help and keep yourself and your
passengers safe:
0 Turn on your hazard flashers.
4-24
ProCarManuals.com

0 Tie a red cloth to your vehicle to alert police that
you’ve been stopped by the snow.
0 Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make body
insulators from newspapers, burlap bags, rags, floor
mats
-- anything you can wrap around yourself or
tuck under your clothing
to keep warm.
You can run the engine to keep warm, but be careful.
L
Snow can trap exhaust gases under your vehicle.
This can cause deadly
CO (carbon monoxide) gas
$0 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 fdster
than just idle. That
is, push the accelerator slightly.
This uses
less fuel for the heat that you get and it
keeps the battery (or batteries) charged. You will need
a well-charged battery (or batteries) to restart the
vehicle, and possibly for signaling later on with your
headlamps. Let the heater
run for awhile.
If you have a diesel engine, you may have to run it at a
higher speed to get enough heat. 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.

RIM COLD TIRE PRI
EE ~ENERS MANUAL FOR ADDITIONAL INFORMATION. -1
The CertificationRire label is found on the rear edge
of the driver’s door. The label shows the size
of your
original tires and the inflation pressures needed to obtain the gross weight capacity your vehicle. This is called
GVWR (Gross Vehicle Weight Rating). The GVWR
includes the weight of the vehicle, all occupants, fuel
and cargo.
4-26
ProCarManuals.com

The CertificatiodTire label also tells you the maximum
weights for the front and rear axles, called Gross Axle
Weight Rating (GAWR).
To fine out the actual loads
on your front and rear axles, you need
to go to a weigh
station and weigh your vehicle. Your dealer can help
you with this.
Be sure to spread out your load equally
on both sides of the centerline.
Never exceed the GVWR for your vehicle,
or the
GAWR for either the front or rear axle.
And, if
you do have a heavy load, you should spread
it
out.
Do not load your vehicle any heavier than
the
GVWR, or either the maximum front or
rear
GAWR. If you do, parts on your vehicle
can break, or it can change the way your
vehicle handles. These could cause you to lose
control. Also, overloading can shorten the life Things
you put inside your vehicle can strike
and injure people in a sudden stop or turn,
or
in a crash.
0 Put things in the cargo area of your vehicle.
Try to spread the weight evenly.
Never stack heavier things, like suitcases,
inside the vehicle
so that some of them are
above the tops of the seats.
Don’t leave an unsecured child restraint in
your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Don’t leave a seat folded down unless you
need
to.

Towin; a Traile
A CAUTION:
If you don’t use the correct equipment and drive
properly, you can lose control when you pull
a
trailer. For example, if the trailer is too heavy, the
brakes may not work
well -- or even at all. You
and your passengers could be seriously injured.
Pull
a trailer only if you have followed all the
steps in this section.
Ask your GM dealer for
advice and information about towing
a trailer
with your vehicle.
NOTICE:
Pulling a trailer improperly can damage your
vehicle and result in costly repairs not covered by
your warranty.
To pull a trailer correctly, follow
the advice in this part, and see your
GM dealer
for important information about towing a trailer
with your vehicle.
Your vehicle can tow
a trailer. To identify what the
vehicle trailering capacity is for your vehicle, you
should read
the information in “Weight of the Trailer”
that appears later
in this section. But trailering is
different than just driving your vehicle by itself.
Trailering means changes
in handling, durability and
fuel economy. Successful, safe trailering takes correct
equipment, and
it has to be used properly.
That’s the reason for this section.
In it are many
time-tested, important trailering tips and safety rules.
Many of these are important for your safety and that of
your passengers. So please read this section carefully
before you pull
a trailer.
