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.
Then here are some tips:
0 Make sure your vehicle is well ventilated, with a comfortably cool
0 Keep your eyes moving. Scan the road ahead and to the sides. Check
interior.
your mirrors and your instruments frequently.
0 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 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.)

Downloaded from www.Manualslib.com manuals search engine 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.
Know how to go uphill. You may want to shift down to a lower gear.
The lower gears help cool your engine and transmission, and you ca\
n
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 you 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 alert to these and \
take
appropriate action.

Downloaded from www.Manualslib.com manuals search engine You can tow trailers to 2,000 pounds (900 kg) with a step bumper hitch, but
if your trailer tongue has a V-shaped foot, your bumper could be damaged
in sharp turns. Check the distance from the front edge of the foot to the
middle of the hitch ball socket.
If the distance is less than 12 inches, take the
foot
off the trailer tongue.
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. 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 bE---:s
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 Pa) 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. Acquai\
nt 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
so responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform, safety chains,
electrical connector, lights, tires and mirror adjustment. If th\
e trailer has
electric brakes, start your vehicle and trailer moving and then\
apply the
4-41

Downloaded from www.Manualslib.com manuals search engine trailer brake controller by hand to be sure the brakes are working. This lets
you check your electricql 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 apd sudden turns.
Passing
You’ll need more passing distance up ahead when you’re to\
wing a trailer.
And, because you’re a good deal longer, you’ll need to g\
o 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
When you’re turning with a trailer, make wider turns than n\
ormal. 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 a different \
turn signal
flasher and extra wiring. The green arrows on your instrument panel wi\
ll
flash whenever you signal a turn or lane change. Properly hooked up, the
trailer lights 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 pan\
el will flash
€or
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 importan\
t
to check occasionally to be sure the trailer bulbs are still \
working.

When You Are Ready to Leave After Parking on a Hill
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, an\
d 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.

To Jump Start Your Vehicle:
1. Check the other vehicle. It must have a 12-volt battery wlm a\
negauve
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 syst\
ems.
You could be injured if the vehicles roll, Set the parking brake
firmly
on each vehicle. Put an automatic transmission in “P” (Park)\
or a
manual transmission
in “N’ (Neutral). If you have a four-wheel drive
vehicle with
a manual transfer case shift lever, be sure the transfer case
is not in “N’ (Neutral).
3. Turn off the ignition on both vehicles. Turn off all lights t\
hat aren’t
needed, and radios. This will avoid sparks and help save both batteries.
And it could save your radio!
I NOTICE:
I
If you leave your radio on, it could be badly damaged. The
repairs wouldn’t be covered by your warranty.
4. Open the hoods and locate the batteries. Find the positive (+) and
negative
(-) terminals on each battery.

they do, you could get a shock. The vehicles could also be damaged.
Before you connect the cables, here are some basic things you should \
how. Positive (+) will go to positive (+) and negative (-) will go to
negative

get
a short that would damage the battery and maybe other parts too.

Your use of gasoline with deposit control additives will help prevent
deposits from forming in your engine and fuel system. That hel\
ps keep your
engine
in tune and your emission control system working properly. It’s \
good
for your vehicle, and you’ll be doing your part for cleaner air.
Many gasolines are now blended with oxygenates. General Motc
recommends that you use gasolines with these blending niaterials,
sucn as
MTBE and ethanol. By doing so, you can help clean the air, especially in
those parts of the country that have high carbon monoxide levels.
In addition, some gasoline suppliers are now producing reformulated
gasolines. These gasolines are specially designed to reduce vehi\
cle
emissions. General Motors recommends that you use reformulated g\
asoline.
By doing
so, you can help clean the air, especially in those parts of the
country that have high ozone levels.
You should ask your service station operators
if their gasolines contain
deposit control additives and oxygenates, and if they have been\

reformulated to reduce vehicle emissions.
Fuels in Foreign Countries
If you plan on driving in another country outside the U.S. or Canada,
unleaded fuel may be hard to find. Do not use leaded gasoline. If you use
even one tankful, your emission controls won’t work well or \
at all. With
continuous use, spark plugs can get fouled, the exhaust system \
can corrode, and your engine oil can deteriorate quickly. Your vehicle’s oxygen sensor
will be damaged. All of that means costly repairs that wouldn’t be covered
by your warranty.
To check on fuel availability, ask an auto club, or contact a ma\
jor oil
company that does business in the country where you’ll be d\
riving.
You can also write us at the following address for advice.
Just tell us where.
you’re going and give your Vehicle Identification Number (VI\
N).
