accessories. You can monitor battery voltage on the
DIC by pressing the SKIP INFO button. The normal
range is 11.5 to 15.5 volts.
CHANGE ENGINE OIL

the life of the engine oil has expired and it should be
changed within 200 miles (322 km). See ªEngine Oilº

will display if the ignition is in RUN to inform the
driver that the brake fluid level is low. Have the brake
system serviced by a technician as soon as possible.
See ªBrake System Warning Lightº in the Index.
CHECK COOLANT LEVEL

CHECK OIL LEVEL - 36: For correct operation
of the low oil sensing system, your vehicle should be on
a level surface. A false CHECK OIL LEVEL message
may appear if the vehicle is parked on grades. The oil
level sensing system does not check for actual oil level
if the engine has been off for a short period of time, and
the oil level is never sensed while the engine is running.
If the CHECK OIL LEVEL message appears and
your vehicle has been parked on level ground with the
engine off for at least 30 minutes, the oil level should
be checked by observing the oil dipstick. Prior to
checking the oil level, be sure the engine has been off
for five minutes and your vehicle is on a level surface.
Then check the dipstick and add oil if necessary.
See ªEngine Oilº in the Index.

just starting to spin, as it might if you hit a patch of ice
or other slippery spot on the road. When the system is
on, you may hear a noise or feel a vibration in the brake
pedal. This is normal.
When the STABILITY ENGAGED message is on,
you should continue to steer in the direction you want
to go. The system is designed to help you in bad
weather or other difficult driving situations by making

STABILITY ENGAGED message comes on, you'll
know that something has caused your vehicle to start to
spin, so you should consider slowing down.STARTING DISABLED REMOVE KEY

cluster will then run a timer and change the messages
to WAIT 2 MINUTES, WAIT 1 MINUTE and then
START CAR. When the START CAR message is
displayed, try again to start the engine.

take your vehicle to a proper service center before
turning off the engine.

!~(Fan): Press the switch with the fan symbol on it
until AUTO is displayed on the screen. This setting
automatically controls the fan speed. If it is cold outside,
the fan may not run in the maximum speed right away.
The system checks the temperature of the engine coolant
to assure it is warm enough to provide heat. When the
engine coolant is warm, the controller allows the fan to
gradually increase to a higher speed. This prevents cold
air from blowing into the passenger compartment. If you
want the fan at a higher speed, press the up arrow until
you see HI on the display. If you want the fan speed to
be automatic, but you want the fan speed to be higher
than the AUTO setting, press the fan symbol until
HI AUTO is shown on the display. If you want the
fan at a lower speed, press the down arrow until LO is
shown on the display. If you want the fan speed to run
lower than the AUTO setting, press the switch until
LO AUTO is shown on the display.OFF: Press this button to turn the system off.
Fresh air will continue to flow through the vehicle,
and the system will try to maintain the previously set
temperature. The outside temperature will show on the
display when the system is OFF.
AC (Air Conditioning): Press this button to turn the
air conditioning on and off. The system will cool and
dehumidify the air inside the vehicle. In the AUTO
mode, the display will show that AC is active, but the
air conditioning compressor only operates when the
system determines it is needed.
(Recirculation): Press this button to limit the
amount of outside air entering your vehicle. This is
helpful when you are trying to cool the air quickly or
limit odors entering your vehicle. In the AUTO mode,
the system will use recirculation as necessary to cool
the air. Pressing the recirculation button will change the
operation to a manual mode and the air will recirculate
non
-stop. Press this button again to turn off the
recirculation feature.
If you notice the windows fogging, press the
recirculation button to exit the recirculation mode.

3-33 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 do the following:
1. Adjust the volume control to the lowest setting.
2. Increase volume slowly until you hear comfortably
and clearly.NOTICE:
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, radio or other systems,
and even damage them. Your vehicle's systems
may also 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.

4-7
Avoid needless heavy braking. Some people drive
in spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic.
This is a mistake. Your brakes may not have time to
cool between hard stops. Your brakes will wear out
much faster if you do a lot of heavy braking. If you
keep pace with the traffic and allow realistic following
distances, you will eliminate a lot of unnecessary
braking. That means better braking and longer
brake life.
If your engine ever stops while you're driving, brake
normally but don't pump your brakes. If you do,
the pedal may get harder to push down. If your
engine stops, you will still have some power brake
assist. But you will use it when you brake. Once the
power assist is used up, it may take longer to stop and
the brake pedal will be harder to push.
Anti-Lock Brake System (ABS)
Your vehicle has anti-lock brakes. ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine and begin to drive away,
your anti
-lock brake system will check itself. You may
hear a momentary motor or clicking noise while this test
is going on, and you may even notice that your brake
pedal moves a little. This is normal.
If there's a problem with
the anti
-lock brake system,
this warning light will stay
on. See ªAnti
-Lock Brake
System Warning Lightº in
the Index.
