It takes a little more or less fuel to fill
up than the gage indicated. For
example, the gage may have indicated
the tank was half full, but it actually
took a little more or less than half the
tank’s capacity to fill the tank.
The gage moves a little when you turn
a corner or speed up.
The gage doesn’t go back to E when
you turn
off the ignition.
For your fuel tank capacity, see
Service

Information on the last page of
this manual.
Oil Pressure Gage (STANDARD
CLUSTER)
Your oil pressure gage shows the oil
pressure in psi (pounds per
square
inch) when the engine is running. Oil
pressure may vary with engine speed,
outside temperature and oil viscosity.
Driving your vehicle with low oil
pressure can cause extensive engine
damage. Have your vehicle serviced
immediately.
NOTICE:
Damage to your engine Gom
neglected
oil problems can be costly
and is not covered by your warranty.

Oil Pressure Gage (ELECTRONIC

CLUSTER)
Your oil pressure gage shows the oil
pressure in psi (pounds per square
inch) when the engine is running. Oil
pressure may vary with engine speed,
outside temperature and oil viscosity.
If you have a problem with your oil, the
box around the oil pressure symbol may
begin to flash
after you start your
engine, or when
you are driving. This
indicates that oil is not going through
your engine quickly enough to keep it
cool. The engine could be low on oil, or
could have
some other oil problem.
Have it
fixed right away.

What Kind of Oil to Use
Beginning midyear 1993, oils of the
proper quality for your vehicle will be
identified with this new “starburst”
symbol. The “starburst” symbol
indicates that the oil has been certified
by the American Petroleum Institute
(API), and is preferred for use in your
gasoline engine.
You should look for this on the front of
the oil container, and use only oils that
display this new symbol.
You should also use the proper viscositJ
oil for your vehicle, as shown in the
following chart:

LOOK FOR
ONE OF THESE
LABELS
SAE 5W-30 PREFERRED
IF NEITHER SAE 5W-30 NOR SAE 1OW-30 GRADE OILS ARE AVAILABLE, SAE 30 GRADE MAY BE USED AT TEMPERATURES WEATHER ABOVE 40 DEGREES F (4 DEGREES c).
DO NOT USE SAE 1OW-40, SAE 2OW-50 OR ANY OTHER GRADE OIL NOT RECOMMENDED.
Is shown in the chart, SAE 5W-30 is
lest for your vehicle. However, you can
Ise
SAE 1OW-30 if it’s going to be 0°F
:-lS.C)
or above. These numbers on an
)il container show its viscosity, or thickness.
Do not
use other viscosity oils,
such as SAE
IOW-40 or SAE 20W-50.
If you cannot find oils with the new
“starburst” symbol on the front of the
container, you should look for and use
oils containing the following three things:
SH or SG
“SH”
or “SG” must be on the oil
container, either by itself or combined
with other quality designations, such as “SH/CD,” “SH,SG,CD,” “SG/CD,” etc.
These letters show American Petroleum Institute (API) levels of quality.
SAE 5W-30
Energy Conserving I1
Oils with these words on the
container will help you save fuel.
These three things are usually included
in a doughnut shaped logo (symbol) on
most containers.
If you cannot find oils
with the “starburst” symbol, you should
look for oils with the doughnut shaped
symbol, containing the three things
noted above.

Explanation of Scheduled
Maintenance Services
Below are explanations of the services
listed in Schedule I and Schedule 11.
The proper fluids and lubricants to use
are listed in Section
D. Make sure
whoever services your vehicle uses
these. All parts should be replaced and
all necessary repairs done before you or
anyone else drives the vehicle.
ITEM SERVICE
NO.
1. Engine Oil and Filter Change* -
Always use SH or SG Energy
Conserving I1 oils of proper viscosity.
The
“SH” or “SG” designation may be
shown alone or in combination with
others, such as “SH/CD,”
“SH, SG,
CD,” “SG/CD,” etc. To determine the
preferred viscosity for your vehicle’s engine (e.g., SAE 5W-30 or SAE 1OW-
30), see the Index under Engine Oil.
2. Chassis Lubrication - Lubricate the
transmission shift linkage, parking
brake cable guides, underbody contact points and linkage. Lubricate the front
suspension and steering linkage.
3. Tire and Wheel Rotation and
Inspection
- For proper wear and
maximum tire life, rotate your tires
following the instructions
in this
manual. See
Tires, Inspection G.
Rotation in the Index. Check the
tires for uneven wear or damage. If
you see irregular or premature wear,
check the wheel alignment. Check for
damaged wheels also.
Inspection - Inspect the drive belt
for cracks, fraying, wear and proper
tension. Replace as needed.
5. Cooling System Service‘: - Drain,
flush and refill the system with new
or approved recycled coolant
conforming to
GM Specification
6038-M. Keep coolant at the proper
mixture as specified. See
CooZant in
the
Index. This provides proper
freeze and boil protection, corrosion
inhibitor level and maintains proper
engine operating temperature.
Inspect hoses and replace if they are
cracked, swollen or deteriorated.
Tighten screw-type hose clamps. Clean the outside of the radiator and
air conditioning condenser. Wash the
pressure cap and neck.
4. Engine Accessory Drive Belt
To help ensure proper operation, we
recommend
a pressure test of both the
cooling system and the pressure cap.
6. Transmission Service - Change
both the fluid and filter every 15,000
miles
(25 000 lun) if the vehicle is
mainly driven under one or more of
these conditions:
In heavy city traffic where the
outside temperature regularly
reaches
90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police
If you do not use your vehicle under
any of these conditions, change both
the fluid and filter every
100,000
miles (166 000 lun) .
Replace spark plugs with the proper
type. See
Replacement Parts in the
Index.
8. Spark Plug Wire Inspection‘%t -
Inspect for burns, cracks or other
damage. Check the boot
fit at the
coils and at the spark plugs. Replace
wires as needed.
