If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
0 Avoiding hard accelerations.
0 Avoiding steep uphill grades.
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady, see “If
the Light
Is On Steady” following.
If the light continues to flash, when it is safe to do
so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart the
engine. If the light remains on steady, see “If the Light
Is On Steady” following. If the light
is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle? If
so, reinstall the fuel cap, making sure to fully install
the cap. The diagnostic system can determine
if the fuel
cap has been left off or improperly installed.
A loose or
missing
fuel cap will allow fuel to evaporate into the
atmosphere.
A few driving trips with the cap properly
installed should
turn the light off.
Did you just drive through a deep puddle of water?
If
so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition.
Make sure to install the fuel cap properly. It
will take a few driving trips to turn the light off.
Have you recently changed brands of fuel?
If
so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index).
Poor fuel quality will cause your
engine not to run as efficiently as designed.
You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
ProCarManuals.com

This will be detected by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It
will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to
fix any mechanical or electrical
problems that may have developed.
Oil Pressure Light
Your vehicle is equipped
with an oil pressure warning
light. Your oil pressure light
lets you know when you
may have a problem with
your engine
oil pressure.
When the engine is running and this light comes on, the
engine oil level may be too low. There may
also be
another problem causing low oil pressure. 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:
r
Damage to your engine from neglected oil
problems can be costly and
is not covered by
your warranty.

Fr. __ Gage
E
EQ
United States Canadian
Your fuel
gage tells you about how much fuel you have
left, when the ignition is on. When the gage first
indicates
EMPTY (E), you still have a little fuel left, but
you should get more soon.
After filling the fuel tank, the gage will not read
FULL
(F) until the ignition is turned on.
Here
are four things that some owners ask about. None
of these show a problem with your fuel gage:
0 At the service station, the gas pump shuts off before
the gage reads FULL
(F).
0 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 Eull, but it actually took a little more
or less than half the tank‘s capacity to fill the tank.
0 The gage moves a little when you turn a corner,
brake or speed up.
0 The gage doesn’t go back to EMPTY (E) when you
turn off the ignition.
Low Fuel Warning Light
If your fuel is low, the
warning light next to the
fuel gage will go on and stay on until you add fuel.
If the warning light is still on after adding fuel, you need
to reset the warning light.
To reset the warning light,
turn the ignition to OFF then to
ON. If the light stays on,
see your dealer for service.
This light will also come on when you turn on the
ignition, but the engine is not running, to show you
it is
working. If it doesn’t come on as you start your vehicle,
have it fixed right away.

Mode Buttons
e RECIRC: Press this button (the light will glow)
to limit the amount
of fresh air entering your vehicle by
recirculating much of the air inside your vehicle. You
may use this setting to limit odors entering your vehicle.
Press the OUTSIDE AIR button (the light on the RECIRC button will go
off) to let outside air circulate
into the vehicle.
OUTSIDE AIR: Press this button (the light will
glow) to send outside air into your vehicle. Using this
setting while trying to defrost or defog the windows will
help clear the vents of moisture. Press the RECIRC
button (the light on the
OUTSIDE AIR button will go
off) to limit outside air entering the vehicle. When the
DEFOG
or DEFROST setting is selected, the system
will automatically go to OUTSIDE AIR mode.
Air Conditioning
On very hot days, your vehicle will cool down more
quickly and economically if you open the windows long
enough to let hot, inside air escape. For all settings,
adjust the temperature control knob and fan speed
as desired.
To get maximum cooling or a quick cool-down on very
hot days, press the A/C and RECIRC buttons (the lights
will glow) and turn the temperature knob to the left
(toward the blue area). Adjust the mode
knob to direct
the air to the desired location. This setting should not be
used for long periods
of time because the air may
become too cold and dry. Push the A/C button again (the
light will go off) to turn
off the air conditioning.
When the air conditioner compressor is on, you may sometimes notice slight changes
in your vehicle’s engine
performance and power. This is normal. The system
is
designed to help fuel economy while it maintains the
desired cooling level.
The air conditioner removes moisture from the air,
so
you may sometimes notice water dripping from under
your vehicle’s engine compartment when it is idling or
after it has been turned off. This is normal.

Heating Defogging and Defrosting
Turn the temperature knob to the right (toward the red
area)
to warm the air.
In the LOWER mode, outside
air will be brought in and
sent through the floor outlets. The heater works best
if
you keep your windows closed while using it.
The BI-LEV setting is designed for use on sunny days
when the air is only moderately warm or cool. On days
like these, the sun may adequately warm your upper
body, but your lower body may not be warm enough.
For the best results,
turn the temperature control knob to
the middle position, and then adjust it for comfort.
If you have the optional engine coolant heater and use it
during cold weather,
0°F (- 18 O C) or lower, your heating
system will provide heat more quickly because the
engine coolant is already warmed. See “Engine Coolant
Heater” in the Index, To
rapidly defrost the windshield, turn the temperature
control knob all the way
to the right (to the red area) and
turn the mode knob
to DEFROST.
Adjust the fan to the highest speed.
To keep the windshield clear and bring in heated air
through the heater ducts, turn the mode knob
to
DEFOG.
When the temperature outside is above freezing, the air
conditioner compressor will
run in these settings to help
remove moisture from the air.
Your vehicle is equipped with side window defogger
vents located on the top of the instrument panel. For
additional side window defogging, turn the mode knob
to the
BI-LEVEL setting and adjust the fan to the
highest speed. Aim the side vents on the instrument
panel toward the side windows. For increased airflow to
the side vents, close the center vents.

Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). This will
allow the heater and defroster to work much better,
reducing the chance of fogging the inside of
your windows.
When you enter a vehicle in cold weather,
turn the
blower fan to
“5” for a few moments before driving
off. This helps clear the intake ducts of snow and
moisture, and reduces the chance of fogging the
inside of your windows.
Keep the area around the base
of the center
instrument panel console and the air path under the
front seats clear
of objects. This helps air to circulate
throughout your vehicle.
In cold weather, operating the system in the
OUTSIDE
AIR mode will improve the time it takes
to warm the vehicle.

Understanding Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise if you ever get
it.
FM Stereo
FM stereo will give you the best sound, but FM signals
will reach only about
10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with
FM signals, causing
the sound to come and go.
Tips About Your Audio System
Hearing damage from loud noise is almost undetectable
until it is
too late. Your hearing can adapt to higher
volumes
of sound. Sound that seems normal can be loud
and harmful to your hearing. Take precautions by
adjusting the volume control
on your radio to a safe
sound level before your hearing adapts to
it.
To help avoid hearing loss or damage:
0 Adjust the volume control to the lowest setting.
0 Increase volume slowly until you hear comfortably
and clearly.
NOTICE:
I
Before you add any sound equipment to your
vehicle
-- like a tape player, CB radio, mobile
telephone or two-way radio
-- be sure you can
add what you want.
If you can, it’s very
important to do it properly. Added sound
equipment may interfere with the operation
of
your vehicle’s engine, Delco Electronics radio or
other systems, and even damage them. Your
vehicle’s systems may interfere with the
operation of sound equipment that
has been
added improperly.
So, before adding sound equipment, check with
your dealer and be sure to check Federal rules
covering mobile radio and telephone units.
