2-61 Oil Pressure Gage
The oil pressure gage shows
the engine oil pressure in psi
(pounds per 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
dangerously low oil level or other problem causing low
oil pressure. Check your oil as soon as possible.CAUTION:
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.

2-62 Security Light
This light will come on
briefly when you turn the
ignition key to START.
The light will stay on until the engine starts. If the light
flashes, the Passlock

System has entered a tamper
mode. If the vehicle fails to start, see ªPasslockº in
the Index.
If the light comes on continuously while driving and
stays on, there may be a problem with the Passlock
System. Your vehicle will not be protected by Passlock,
and you should see your GM dealer.
Daytime Running Lamps Indicator Light
You have this light on the
instrument panel. It will
light whenever the DRL are
on. It is also a reminder to
turn on your headlamps
when driving at night.
Check Gages Light
The CHECK GAGES light
will come on briefly when
you are starting the engine.
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.

2-63 Fuel Gage
The fuel gage, when the
ignition is on, tells you
about how much fuel you
have left in your tank.
(United States version,
Canada similar.)
The gage will first indicate E (Empty) before you are
out of fuel, and you should get more fuel as soon
as possible.Listed are four situations you may experience with your
fuel gage:

At the gas station, the fuel pump shuts off before the
gage reads F (Full).

It takes a little more or less fuel to fill up than the
fuel 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 (Empty) when you
turn off the ignition.
None of these indicate a problem with the fuel gage.

heater controls will look like this.Fan Knob
The knob on the left side of the heating system control
panel controls the fan speed. The knob has four speed
positions. To increase airflow, turn the knob toward HI.
To decrease airflow, turn it toward LO. To turn the fan
off, turn the mode knob on the far right to OFF.
Temperature Knob
The middle knob on the control panel controls the
temperature of the air flowing into your vehicle. Turn
the knob toward the red area for warmer air. Turn the
knob toward the blue area for cooler air.
Mode Knob
The right knob changes the heater setting.
VENT: This setting directs air through the
instrument panel vents.
BI-LEVEL: Use this setting to divide airflow
between the heater floor vents and instrument
panel vents.
HEAT: This setting directs air through the heater
floor vents. This setting is useful for cold weather.

economy. This setting also cools the air the fastest.
After the vehicle's interior reaches a comfortable
temperature, turn the knob clockwise to place the
air conditioning system in the A/C mode.

A/C: Use for normal cooling on hot days. This setting
cools outside air and directs it through the instrument
panel outlets.
BI-LEVEL A/C: Use this setting to divide airflow
between the heater floor vents and instrument panel
vents. The air conditioning compressor may operate in
this setting to cool the air.
VENT: This setting directs air through the
instrument panel vents.
HEAT: This setting directs air through the heater
floor vents. This setting is useful for cold weather.
HEAT/DEFROST: Use this setting to divide
airflow between the heater floor vents and windshield.
DEFROST: This setting directs air through the
windshield defroster vents. This setting is useful when
you have fog or ice on the windshield.
Rear Heater (Without Air Conditioning)
If you have a rear heater (without rear air conditioning),
the control switch is located on the instrument panel.
To increase and decrease the flow of heated air to the
rear floor vents, turn the thumbwheel marked REAR

The knob has three speed positions. To increase the flow
of heated air, turn the thumbwheel toward HIGH. To
turn the fan off, turn the switch to OFF.
