Fuel Gage
Your fuel gage tells you about how
much fuel you have left, when the
ignition is on. When the indicator nears
E (Empty), you still have a little fuel left,
but yonshould get more soon.
Here arethree things that some owners
ask about. None of these show a
problem
with your fuel gage:
At the gas station, with your ignition
on, the gas pump shuts
off before the
gage reads
F (Full).
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.
For your fuel tank capacity, see
Service
Station Information
on the last page of
this manual.

Engine Coolant Temperafure
Gage
You have a gage that shows the engine
coolant temperature. If the gage pointer
moves into the red area, your engine is
too hot!
That reading means the same thing as
the warning light. It means that your
engine coolant has overheated. If you
have been operating your vehicle under
normal driving conditions you should
pull
off the road, stop your vehicle and
turn
off the engine as soon as possible.
HOT COOLANT CAN BURN YOU
BADLY!

Problems on the Road,. this manual
shows what to
do. See the Index under

NOTICE:
If you keep driving your vehicle
with this light on, after
a while the
emission controls won’t work as
well, your fuel economy won’t be as

When this light comes on it means one
of these four things:
You have approximately 3 gallons
(12 L) or less of fuel remaining in
your tank. Check your fuel gage.
Your oil pressure is low. Check your
oil pressure indicator.
Your engine is too hot. Check your
coolant temperature gage.
There is a problem with the charging
system.
Head-Up Displcly (OP~ONJ
If you have the optional Head-Up
Display (HUD), you can see the
speedometer reading, in English or
metric units, displayed “through” the

HUD also shows:
Turn signal indicator lights.
A high beam indicator symbol.
A CHECK GAUGES message. (For
low oil pressure, high coolant
temperature, high or low battery
voltage, and low fuel.)

should.
Use
a mixture of one-half dean-water
(preferably distilled) and one-half
antifreeze that meets
“GM Specificatkm
1825-M,” which won’t damage
aluminum parts.
You can also use a
recycled coolant conforming
to GM
Specification 1825-M with
a complete coolant
flush and refill.
If you use this
mixture, you don’t need to add
anything
else.

Service & Appearance Care
Radiator Pressure Cap
NOTICE:
Your radiator cap is a 15 psi
(105kPa) pressure-type cap and
must be tightly. installed

I Power Steering Fluid
How To Check Power Steering
When you replace your radiator premre
cap, an
AC@ cap is recommended.
Thermostat
Engine coolant temperature is
controlled by a thermostat in the engine
coolant system. The thermostat stops
the flow of coolant through the radiator
until the coolant reaches a preset
temperature.
When you replace your thermostat, an
AC@ thermostat is recommended.
Fluid
-
Unscrew the cap and wipe the dipstick
with a clean rag. Replace the cap and
completely tighten it. Then remove the
cap again and look at the fluid level on
the dipstick.
When the engine compartment is hot,
the level should be at the
H mark.
When the engine compartment is
cool, the level 'should be at the
C
mark.
What to Add
Refer to the Maintenance Schedule to
determine what kind of fluid to use. See

Mainfenance Services
Following 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 10W-30), see
Engine Oil
in the Index.
2. Chassis Lubrication - Lubricate
suspension and steering linkage.
Lubricate the transaxle shift linkage,
and parking brake cable guides,
underbody contact points and
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 6
Rotation in the hdex. 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 belt for
cracks, fraying, wear and proper
tension. Replace as needed.
5. Camshaft Timing Belt Inspection
(3.4L Code X engine only) * -
Inspect for cracks, wear or oiliness.
Check tensioner for proper operation.
See the service manual.
(To purchase
4. Engine Accessory Drive Belt
a service manual, see Service
Publications
in the Index.) Replace
parts as needed.
6. Cooling System Service* - Drain,
flush and refill the system with new
or approved recycled. coolant
conforming
to GM Specification
1825M. Keep coolant at the proper
mixture as specified. See
Coolant 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.
Clean the outside of the radiator and
air conditioning condenser. Wash the
pressure cap and neck.
To help ensure proper operation, we
recommend a pressure test of both
the cooling system and the pressure
cap.
