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, th\
ere
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.
Some Other Rainy Weather Tips
Turn on your low-beam headlights - not just your parking lights - to
help make you more visible to others.
Besides slowing down, allow some extra following distance. And be
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.)

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.
0 Try to use the freeways that rim and crisscross most large cities. You’ll
save time and energy. (See the next part, “Freeway Driving.”)
0 Treat a green light as a warning signal. A traffic light is there because
the corner is busy enough to need it. When a light turns green, and just
before you start to move, check both ways for vehicles that have not
cleared the intersection
or may be running the red light.

Mile for mile, freeways (also called thruways, parkways, expressways,
turnpikes, or superhighways)
are the safest of all roads. But they have their
own special rules.
The most important advice on freeway driving is: Keep up with traffic and
keep to the right. Drive at the same speed most of the other drivers are
driving. Too-fast or too-slow driving breaks a smooth traffic flow. Treat
the
left lane on a freeway as a passing lane.
At the entrance there is usually a ramp that leads to the freeway. If you have
a clear view of the freeway as you drive along the entrance ramp, you
should begin to check traffic. Try to determine where you expect to blend
with the
flow. Try to merge into the gap at close to the prevailing speed.
Switch on your turn signal, check your mirrors and glance over your
shoulder as often as necessary.
Try to blend smoothly with the traffic flow.
Once you are on the freeway, adjust your speed to the posted limit or to the
prevailing rate if it’s slower. Stay in the right lane unless you want to pass.
Before changing lanes, check your mirrors. Then use your turn signal.
Just before you leave the lane, glance quickly over your shoulder to make
sure there
isn’t another vehicle in your ‘.‘blind” spot.
Once you are moving on the freeway, make certain you allow a reasonable
following distance. Expect to move slightly slower at night.
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.
4-28

Downloaded from www.Manualslib.com manuals search engine 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 dealerships
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:
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?
Lights: Are they all working? Are the lenses clean?
0 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?
Weather Forecasts: What’s the weather outlook along your route?
Maps: Do you have up-to-date maps?
Should
you delay your trip a short time to avoid a major storm system?
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 than a
second,
and you could crash and be injured.
What can you
do about highway hypnosis? First, be aware that it can
happen.

Downloaded from www.Manualslib.com manuals search engine 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
may offer the least traction
of all. You can get “wet ice” when it’s about
freezing
(32 OF; 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.
4-32

Downloaded from www.Manualslib.com manuals search engine 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 awhile.
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.

Downloaded from www.Manualslib.com manuals search engine 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
If your trailer weighs more than 1,000 pounds (450 kg) loaded, then it needs
its own brakes
- and they must be adequate. Be sure to read and follow the
instructions for the trailer brakes
so you’ll be able to install, adjust and
maintain them properly.
Your trailer brakes system can tap into vehicle’s hydraulic brake system
except:
Don’t tap into your vehicle’s brake system if the trailer’s brake system will
use more than 0.02 cubic inch (0.3~~) of fluid from your vehicle’s master
cylinder. If it does, both braking systems won’t work well. You could even
lose your brakes.
Will the trailer parts take 3,000 psi (20 650 kPa)
of pressure? If not, the
trailer brake system must not be used with your vehicle.
If everything checks out this far, then make the brake fluid tap at
the port on
the master cylinder that sends fluid to the rear brakes. But don’t use copper
tubing for this. If you do, it will bend and finally break off. Use steel brake
tubing.
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, lights, 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 lights and any trailer brakes are still working.

1. Apply your regular brakes and hold the pedal down while you:
Start your engine;
Shift into a gear; and
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 fluid (don’t
overfill), engine oil, axle lubricant, belt, cooling system, and brake
adjustment. 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 these
sections before you start your trip.
Check periodically to
see that all hitch nuts and bolts are tight.
