Downloaded from www.Manualslib.com manuals search engine Here are things some owners ask about. None of these indicate a problem
with your fuel gage:
0 At the gas station, the gas pump shuts off before the gage r\
eads full.
The fuel tank will take either a little more or a little less fuel to fill up
than the gage shows.
The gage moves a little when you turn a corner or speed up.
The gage doesn’t go back to empty when you turn off the ignition.
For your fuel tank capacity, see the Index under “Fluid Capacities.”
Oil Pressure Gage
Standard Cluster Digital Cluster
The oil pressure gage shows the engine oil pressure in psi (pounds pe\
r
square inch) when the engine is running. Canadian vehicles indicate
pressure in
kPa (kilopascals). 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 dangerous\
ly low oil
level or other problems causing low oil pressure.
On the digital cluster, a box around the oil pressure symbol \
will begin to
flash when the oil pressure
is low.

Downloaded from www.Manualslib.com manuals search engine Just before you leave the lane, glance quickly over your shoulder to make
sure there isn’t another vehicle in your “blind” spot.
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 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
inside and outside?
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?
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 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.
The
coolant level should be at or above FULL. If it isn’t, you may have a
leak in the radiator hoses, heater hoses, radiator, water pump or somewhere
else in the cooling system.
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.

NOTICE:
Be careful with a hair dryer or heat lamp. You could scorch the
fabric.
0 Wipe with a clean cloth.
Using Solvent-Type Cleaner on Fabric
First, see if you have to use solvent-type cleaner at all. Some spots and
stains will clean off better
with just water and mild soap.
If
you need to use a solvent:
0 Gently scrape excess soil from the trim material with a clean, dull knife
or scraper. Use
very little cleaner, light pressure and clean cloths
(preferably cheesecloth). Cleaning should start
at the outside of the
stain, “feathering” toward the center. Keep changing to a clean section
of the cloth.
0 When you clean a stain from fabric, immediately dry the area with an
air hose, hair dryer,
or heat lamp to help prevent a cleaning ring. (See
the previous
NOTICE.)

temperature is
10°F (-1 2°C) or higher. When the weather is cold, let
them warm up before lubricating them or they could be damaged.\

Also, be sure to check all the vehicle fluid levels at this \
time.
COOLING SYSTEM SERVICE* - Drain, flush and refill the
system
with new or approved recycled coolant conforming to “GM
Specification 6038-M”. See “Engine Coolant”
in the Index for the
proper coolant and mixture to use
in your vehicle.
Also inspect the hoses and replace them
if they are cracked, swollen, or
deteriorated. Clean the outside of the radiator and air conditioning
condenser. Wash the radiator neck.
To ensure proper operation,
pressure test the radiator and cap.
AIR CLEANER FILTER REPLACEMENT* - Replace at
specified intervals. Ask your dealer for the proper replacement
intervals for your driving conditions.
