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.

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.

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
See “Trailer Wiring Harness” in the Index.

on each vehicle. Put an automatic transmission in PARK (P) or a
manual transmission in NEUTRAL
(N). If you have a
four-wheel-drive vehicle with a manual transfer case shift lever, be
sure the transfer case
is not in NEUTRAL (N).
3. Turn off the ignition on both vehicles. Turn off all lights that aren’t
needed, and radios. This will avoid sparks and help save both batteries
And it could save your radio!
NOTICE:
If you leave your radio on, it could be badly damaged. The
repair wouldn’t be covered by your warranty.
~~
4. Open both hoods and locate the batteries. Find the positive (+) and
negative
(-) terminals on each battery.
5. Check that the jumper cables don’t have loose or missing insulation. If
they do, you could get a shock. The vehicles could be damaged too.
Before you connect the cables, here are some basic things you should
know. Positive (+) will go to positive (+) and negative (-) will go to
negative
(-) or a metal engine part. Don’t connect (+) to (-) or you’ll
get a
short that would damage the battery and maybe other parts too.

hole.
3. If the fluid level is good, install the plug and be sure it is fully seated. If
the fluid level is low, add more fluid as described in the next steps.
How to Add Fluid
Here’s how to add fluid. Refer to the Maintenance Schedule to determine
what kind
of fluid to use. See “Recommended Fluids and Lubricants’’ in the
Index.
1. Remove the filler plug.
2. Add fluid at the filler plug hole. Add only enough fluid to bring the
fluid level up to the bottom
of the filler plug hole.
3. Install the filler plug. Be sure the plug is fully seated.
Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is self-adjusting. A slight
amount
of play (1/4 inch to 1/2 inch) in the pedal is normal.

,:
If the level is below
the bottom
of the filler
plug hole, you’ll need
to add some lubricant.
If the differential
is at operating temperature (warm), add enough lubricant
to raise the level to the bottom of the filler plug hole.
If the differential is cold, add enough lubricant to raise the le\
vel to 1/2 inch
(12 mm) below the filler plug hole.
What to Use
Refer to the Maintenance Schedule to determine what kind of lubricant to
use. See “Recommended Fluids and Lubricants”
in the Index.
Engine Coolant
The following explains your cooling system and how to add coolant \
when it
is low. If you have a problem with engine overheating, see “Engine
Overheating”
in the Index.
The proper coolant
for your vehicle will:
0 Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 262°F (128°C).
0 Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they should.
What to Use
Use a mixture of one-half clean water (preferably distilled) and one-half
antifreeze that meets “GM Specification 6038-M,” which won’t damage
aluminum parts.
You can also use a recycled coolant conforming to “GM
Specification 6038-M.
Use GM Coolant Supplement (Sealer) with a
complete coolant flush and refill. If
you use this mixture, you don’t need to
add anything else.

The headlamp wiring is protected by a circuit breaker in the light switch. An
electrical overload will cause the lights to go on and off, or in some cases to
remain
off. If this happens, have your headlamp wiring checked right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit breaker and a fuse. If
the motor overheats due to heavy snow, etc., the wiper will stop until the
motor cools. If the overload is caused by some electrical problem and not
snow, etc., be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power windows and other
power accessories. When the current load is too heavy, the cir\
cuit breaker
opens and closes, protecting the circuit until the problem is fixed.
Trailer Wiring Harness
The optional seven-wire trailer wiring harness is protected by an in-line
fuse in the battery feed wire. This fuse is near the junction block in the
front, driver’s side fender. See “Trailer Wiring Harness” in the
Features &
Controls section.
Fuse B/ock
The fuse block is in
the instrument panel
on the driver’s side.
Remove the cover by
turning the fastener
counterclockwise.
Then you can remove
fuses with a fuse
extractor. Extra fuses
are provided in the
cover.
