The oil pressure gage
pressure
in psi (pounds
shows
the engine oil
per square inch) when the
engine is running. Canadian
vehicles indicate pressure
in kPa (kilopascals).
OIL 93
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a
dangerously low
oil level or other problem causing low
oil pressure. Check your oil as soon as possible.
A C -1TION:
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
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

Fuel Gage
UNLEADED
FUEL ONLY
The fuel gage, when the
ignition is on, tells you
about how much fuel you
have left
in your tank.
If the light comes on and stays on while you are driving,
check your coolant temperature
and engine oil pressure
gages to see
if they are in the warning zones. The
gage will first indicate EMPTY
(E) before you
are out of fuel, and you should get more fuel as soon
as possible.

Downloaded from www.Manualslib.com manuals search engine 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.
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
dealers 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:

Wiper Blades: Are they in good shape?

Lamps: 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?
Weather Forecasts: What’s the weather outlook
along your route? Should
you delay your trip a short
time to avoid
a major storm system‘?
Maps: Do you have up-to-date maps?

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.
Main ~ mr ~ ce 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 Wiring Harness
The eight-wire harness, if you have one, is stored under
your vehicle along the rear frame crossmember. It is
wrapped and bound with a plastic strap. The harness has
a 30-amp battery feed and no connector, and
you should
have a qualified electrical service person wire your
harness for
you. Attach the harness to the trailer, then
tape or strap
it to your vehicle’s frame rail. Be sure you
leave it loose enough so the wiring doesn’t bend or
break, but not
so loose that it drags on the ground.
Store the harness in its original place. Wrap the harness
together and tie it neatly
so it won’t be damaged.
The five-wire harness, if you have one, is stored inside
the vehicle at
the passenger side rear corner, behind the
jack. This should be wired by a qualified electrical
service person.
It must be routed out of your vehicle
between the rear door and the floor, with enough of the
harness left on both sides
so that the trailer or the body
won’t pull
it.
Store the harness in its original place. Wrap the harness
together and tie it neatly
so it won’t be damaged.

-- Gasoline Engines
If you plan on driving in another country outside the

or Canada, the proper fuel may be hard to
find. Never use leaded gasoline or any other
fuel not
recommended in
the previous text on fuel. Costly repairs
caused by use of improper fuel wouldn’t be covered by

~ To check on fuel availability, ask an auto club, or
1 contact a major oil company that does business in the
j country where you’ll be driving.

Filling Your Tank

Gasoline vapor is highly flammable. It burns
violently, and that can cause very bad injuries.
Don’t smoke if you’re near gasoline or refueling
your vehicle. Keep sparks, flames and smoking
materials away.from gasoline.

Downloaded from www.Manualslib.com manuals search engine Engine Oil (Gasoline Engine)
If your vehicle has a diesel engine, see “Engine Oil
(Diesel Engine)” in the Diesel Engine Supplement.
It’s
a good idea to check your engine oil every time you
get fuel.
In order to get an accurate reading, the oil must
be warm and the vehicle must be
on level ground.
Turn off the engine and give the
oil a few minutes to drain
back
into the oil pan. If you
don’t, the oil dipstick might
not show the actual level.
Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or
cloth, then push
it back in all the way. Remove it again,
keeping
the tip down, and check the level.
When to Add Oil
If the oil is at or below the ADD mark, then you’ll need to
add some
oil. But you must use the right kind. This part
explains what kind
of oil to use. For crankcase capacity,
see “Capacities and Specifications”
in the Index.
I NOTICE:
Don’t add too much oil. If’ your engine has so much
oil that the oil level gets above the upper mark that
shows the proper operating range,
your engine
could be damaged.

Downloaded from www.Manualslib.com manuals search engine Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83
000 km) if the vehicle’s GVWR is over 8,600 or
if
the vehicle is mainly driven under one or more of
these conditions:
0 In heavy city traffic where the outside temperature
0 In hilly or mountainous terrain.
regularly reaches
90°F (32°C) or
higher.
0 When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
If your vehicle’s
GVWR is not over 8,600 and you do
not use your vehicle under any
of these conditions, the
fluid and filter do
not require changing.
See “Scheduled Maintenance Services” in the Index.
How to Check
.Because this operation can be a little difficult, you
may choose to have this done at your GM dealer
Service Department.
If you do it yourself, be sure
to follow all the
instructions here, or you could get a false reading
on
the dipstick.
NOTICE:
Too much or too little fluid can damage your
transmission. Too much can mean that some of
the
fluid could come out and fall on hot engine
parts or exhaust system parts, starting a fire. Be
sure to get an accurate reading if you check your
transmission
fluid.
