The CHECK GAGES light
will come
on briefly when
you are starting the engine.
CHECK
GAGES
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:

Windshield Washer Fluid: Is the reservoir full? Are
all windows clean inside and outside?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
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?

Downloaded from www.Manualslib.com manuals search engine Run your engine only as long as you must. This saves
fuel. When
you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly.
This uses less fuel for the heat that you get and
it
keeps the battery (or batteries) charged. You will need
a well-charged battery (or batteries) to restart the
vehicle, and possibly for signaling later on with your
headlamps. Let the heater run for awhile.
If
you have a diesel engine, you may have to run it at a
higher speed to get enough heat. Then, shut the engine
off and close the window almost all the way to preserve
the heat. Start the engine again and repeat this
only
when you feel really uncomfortable from the cold. But
do it
as little as possible. Preserve the fuel as long as you
can. To help keep warm, you can get out of the vehicle
and do some fairly vigorous exercises every half hour or
so until help comes.
Loading Your Vehicle
The Certificationflire label is found on the rear edge
of the driver’s door. The label shows the size of your
original tires and the inflation pressures needed to obtain
the gross weight capacity your vehicle. This is called
GVWR (Gross Vehicle Weight Rating). The GVWR
includes
the weight of the vehicle, all occupants, fuel
and cargo.

this procedure
if coolant begins to flow out of the
filler neck, reinstall the pressure cap. Be sure the
arrows
on the pressure cap line up like this.
Engine Fan Noise
Your vehicle has a clutched engine cooling fan. When the
clutch is engaged,
the fan spins faster to provide more air
to cool the engine. In most every day driving conditions,
the fan
is spinning slower and clutch is not fully engaged.
This improves fuel economy and reduces fan noise.
Under heavy vehicle loading, trailer towing and/or high
outside temperatures, the fan speed increases
as the clutch
more
fully engages. So you may hear an increase in fan
noise. This
is normal and should not be mistaken as the
transmission slipping
or making extra shifts. It is merely
the cooling system functioning properly. The fan will
slow down when additional cooling is not required and
the clutch partially disengages.
You may also hear this Fan noise when you start
the engine. It will go away as the fan clutch
partially disengages.

Downloaded from www.Manualslib.com manuals search engine Inflation -- Tire Pressure
The Certificationflire label, which is on the rear edge of
the driver’s door, shows the correct inflation pressures
for your tires when they’re cold. “Cold” means your
vehicle has been sitting for at least three hours or driven
no more than 1 mile (1.6 km).
I NOTICE:
Don’t let anyone tell you that .underinflation or
overinflation is
all right. It’s not. If your tires
don’t have enough air junderinflation), you can
get the following:
Too much flexing
Too much heat
0 Tire overloading
Bad wear
Bad handling
Bad fuel economy.
NOTICE: (Continued)
I NOTICE: (Continued) I
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.
When to Check
Check your tires once a month or more. Also, check the
tire pressure of the spare tire.
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell
if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure
to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and moisture.

Downloaded from www.Manualslib.com manuals search engine At Least Once a Month
Tire Inflation Check
Make sure tires are inflated to the correct pressures. See
“Tires” in the Index for further details.
Cassette Deck Service
Clean cassette deck. Cleaning should be done every
50 hours of tape play. See “Audio Systems” in the
Index for further details.
At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages are
working properly. Look for any other loose or damaged
safety belt system parts. If you see anything that might
keep
a safety belt system from doing its job, have it
repaired. Have any torn or frayed safety belts replaced.
Also look for any opened or broken air bag covers,
and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)
Automatic Transmission Check
Check the transmission fluid level; add if needed. See
“Automatic Transmission”
in the Index. A fluid loss
may indicate
a problem. Check the system and repair
if needed.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
specified in Part
D.
Body Lubrication Service
Lubricate all hood hinges, hood prop rod pivot, fuel
filler door, rear compartment hinges, latches, locks and
any moving seat hardware. Door hinges are lubricated
for the life
of your vehicle; no additional lubrication is
required. Part
D tells you what to use. More frequent
lubrication may be required when exposed
to a
corrosive environment.
