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

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.)

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.

Try to have a GM dealer or a professional towing service tow your vehicle.
They can provide the right equipment and know how to tow it without
damage.
If your vehicle has been changed since
it was factory-new by adding things
like fog lamps, aero skirting, or special tires and wheels, these things\
could
be damaged during towing.
Before you do anything, turn on the hazard warning flashers.
When you call, tell the towing service:
That your vehicle has rear-wheel drive, or that it has the four-wheel

Downloaded from www.Manualslib.com manuals search engine When your vehicle is being towed, have the ignition key off. The steering
wheel should be clamped in a straight-ahead position
with a clamping
device designed for towing service.
Do not use the vehicle’s steering
column lock for this. The transmissi,on (either automatic or manual) should
be
in “N’ (Neutral) and the transfer case (either manual shift or electronic
shift),
if you have one, should be in 2 HI. The paking brake should be
released.

If you get the overheat warning but see or hear no steam, the problem may
not be too serious. Sometimes the engine can get a little too hot when you:
0 Climb a long hill on a hot day.
0 Stop after high speed driving.
0 Idle for long periods in traffic.
0 Tow a trailer.
If you get the overheat warning with no sign of steam, try this for a minute
or
so:
1. If you have an air conditioner, turn it off.
2. Turn on your heater to full hot at the highest fan speed and open the
window as necessary.
3.
If you’re in a traffic jam, shift to “N” (Neutral).
If you no longer have the overheat warning, you can drive. Just to be safe,
drive slower for about ten minutes. If the warning doesn’t come back on,
you can drive normally.
If the warning continues, pull over, stop, and park your vehicle \
right away.
If there’s still no sign
of steam, push the accelerator until the engine speed is
about twice as fast as normal idle speed. Bring the engine speed back to
normal idle speed after two or three minutes. Now see
if the warning stops.
But then,
if you still have the warning, TURN OFF THE ENGINE AND
GET EVERYONE
OUT OF THE VEHICLE until it cools down.
You may decide not to lift the hood but to get service help right away.
When you decide it’s safe to lift the hood,
here’s what you’ll see:
A. Coolant recovery tank
B. Radiator pressure
C. Engine fan
cap
If the coolant inside the coolant recovery tank is boiling, don’t do anything
else until it cools down.

Downloaded from www.Manualslib.com manuals search engine The coolant level should be at or above the ADD mark. If it isn’t, you may
have a leak in the radiator hoses, heater hoses, radiator, wat\
er pump or
somewhere else in the cooling system.
I NOTICE:
Engine damage from running your engine without coolant isn’t \
covered
by your warranty.
If there seems to be no leak, start the engine again. See if the fan speed
increases when idle speed is doubled by pushing the accelerator\
pedal down.
If it doesn’t, your vehicle needs service. Turn off the engine.
