Downloaded from www.Manualslib.com manuals search engine Freeway Driving
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.
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.

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?
0 Fuel, Engine Oil, Other Fluids: Have you checked all levels?
0 Lights: 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?
0 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.

0 Make sure your vehicle is well ventilated, with a comfortably cool
interior.
0 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 regularly in steep country, or if you’re plann\
ing 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.
0 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.

Downloaded from www.Manualslib.com manuals search engine Safety Chains
You should always attach chains between your vehicle and your trail\
er.
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.

Downloaded from www.Manualslib.com manuals search engine Driving with a Trailer
lowing 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.
Following Distance
Stay at least twice as far behind the vehicle ahead as you would when
driving your vehicle without
a trailer. This can help you avoid situations that
require heavy braking and sudden turns.
4-44

Downloaded from www.Manualslib.com manuals search engine Passing
You’ll need more passing distance up ahead when you’re towing a trailer.
And, because you’re a good deal longer, you’ll need to go much farther
beyond the passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand. Then, to move the
trailer to the left, just move that hand to the left. To move the trailer to the
right, move your hand to the right. Always back up slowly and, if possible,
have someone guide you.
Making Turns
NOTICE:
Making very sharp turns while trailering could cause the traile\
r
to come in contact with the vehicle. Your vehicle could be
damaged. Avoid making very sharp turns while trailering.
When you’re turning with a trailer, make wider turns than normal. Do this
so your trailer won’t strike soft shoulders, curbs, road signs, trees, or other
objects. Avoid jerky or sudden maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have extra wiring and a
heavy-duty
turn signal flasher (included in the optional trailering package).
The green arrows on your instrument panel will flash whenever you signal a
turn or lane change. Properly hooked up, the trailer lamps will also flash,
telling other drivers you’re about to turn, change lanes or stop.
When towing a trailer, the green arrows on your instrument panel will flash
for turns even if the bulbs on the trailer are burned out. Thus, you may think
drivers behind you are seeing your signal when they are not. It’s important
to check occasionally to be sure the trailer bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start down a long or steep
downgrade. If you don’t shift down, you might have to use your brakes
so
much that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your speed to around 45 mph
(70 Wh) to reduce the possibility of engine and transmission overheating.

1. Apply your regular brakes and hold the pedal down while you:
Start your engine;
0 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.
Trailer Lighting Systems Wiring

Downloaded from www.Manualslib.com manuals search engine Jump Starting
If your battery has run down, you may want to use another vehicle and some
jumper cables
to start your vehicle. But please follow the steps below to do
it safely.
NOTICE:
Ignoring these steps could result in costly damage to your
vehicle that wouldn’t be covered by your warranty.
Trying to
start your vehicle by pushing or pulling it could
damage your vehicle, even
if you have a manual transmission.
And if you have an automatic transmission, it won’t start that
way.
To Jump Start Your Vehicle:
1. Check the other vehicle. It must have a 12-volt battery with a negative
ground system.
NOTICE:
If the other system isn’t a 12-volt system with a negative
ground, both vehicles can be damaged.
2. Get the vehicles close enough so the jumper cables can reach, but be
sure the vehicles aren’t touching each other. If they are, it could cause
a
ground connection you don’t want. You wouldn’t be able to start your
vehicle, and
the bad grounding could damage the electrical systems.
