Plugging the cord into an ungrounded outlet could cause an electrical
shock.
Also, the wrong kind of extension cord could overheat and
cause a fire. You could be seriously injured. Plug the cord into a
properly grounded three-prong

Oil Pressure Gage
Standard Cluster Digital Cluster
The oil pressure gage shows the engine oil pressure in psi (\
pounds per square inch) when the engine is running. Canadian vehicles ind\
icate pressure
in kPa (kilopascals). Oil pressure may vary with engine speed\
, outside
temperature and oil viscosity, but readings above the low press\
ure zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a dangerous\
ly low oil
level or other problem causing oil pressure.
On the digital cluster, a box around the oil pressure symbol \
will begin to flash
when the
oil pressure is low.
CAUTION
Don't keep driving if the oil pressure is low. If you do, your engine
can become
so hot that it catches fire. You or others could be
burned. Check your oil as soon as possible and have your vehi\
cle
serviced.

soiled, dampen a clean,
soft cloth in a mild, neutral detergent solution and
clean
it, wiping from the center to the edge.

Downloaded from www.Manualslib.com manuals search engine Driving On a Long nip
Although most long trips today are made on freeways, there are still many
made on regular highways.
Long-distance driving on freeways and regular highways is the same in some
ways. The trip has to be planned and the vehicle prepared, you drive at
higher-than-city speeds, and there are longer turns behind the wheel. You’ll
enjoy your trip more
if you and your vehicle are in good shape. Here are
some tips for a successful long trip.
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
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?
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?
Should you delay your trip a short time to avoid a major storm system?
inside and outside?
Weather Forecasts: What’s the weather outlook along your route?
Maps: Do you have up-to-date maps?
On the Road
Unless you
are the only driver, it is good to share the driving task with
others. Limit turns behind the wheel to about
100 miles (160 km) or two
hours- at a sitting. Then, either change drivers or stop for some refres\
hment
like coffee, tea or soft drinks and some limbering up. But
do stop and move
around. Eat lightly along the way. Heavier meals tend to make some people
sleepy.

You really should not park your vehicle, with a trailer attached, \
on a hill. If
something goes wrong, your rig could start to move. People can be injured,
and both your vehicle and the trailer can be damaged.
But
if you ever have to park your rig on a hill, here’s how to do it:
1. Apply your regular brakes, but don’t shift into P (Park) yet.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the
chocks absorb
the load.
4. Reapply the regular brakes. Then apply your parking brake, and \
shift to
P (Park).
5. Release the regular brakes.
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 ove\
rfill),
engine oil, axle lubricant, belt, cooling system, and brake adj\
ustment. 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.

See “Trailer Wiring Harness” in the Index.

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.
PO424
When you decide it’s safe to lift the hood, here’s what \
you’ll see:
A. Coolant recovery tank
B. Radiator pressure cap
C. Engine fan
If the coolant inside the coolant recovery tank is boiling, don’t do anything
else until
it cools down.
