Change Oil Soon Light
CHANGE OIL
SOON
Your CHANGE OIL SOON
light should come on as a
bulb check when you start
the engine. If this light stays
on for about 20 seconds
afte.r you turn
on the
ignition, have the oil
changed.
When to change your oil also depends
on driving habits
and conditions because they directly affect engine speed,
coolant temperature and vehicle speed. Because
of this,
the CHANGE OIL SOON light may come on as early as
2,000 miles (3,200 km) or less for harsh conditions. Remember,
after changing your engine
oil, the system
must be reset; with the ignition key in the
RUN position,
but the engine off,
fully push and release the accelerator
pedal three times within five seconds.
If the CHANGE
OIL SOON light flashes two times, the system is reset.
However if the light comes on and stays on for five
seconds, it did not reset. You’ll need to reset the system
again. (If you have a driver information center, the
system may be reset
by depressing the DIC RESET
button for five seconds while viewing the oil life display
on the DIC. See “Driver Information Center” later in
this section.)

Fuel Gage Low Fuel Light
1 12
Your fuel gage tells you
about how much fuel you
have left when the ignition
is on. When the indicator
nears
EMPTY (E), you still
have a little fuel
left, but
you should get more soon.
Here are some things owners ask about. All these
situations are normal and do not show a problem with
your fuel gage:
At the service station, the pump shuts off before the
gage reads
FULL (F).
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 it.
0 The gage moves a little when you turn a corner or
speed up. If
your fuel is low, a circular
light
on your instrument
panel cluster will come
on
and stay on and a chime will
sound periodically until you
add fuel. It will also come
on for a few seconds when
you first turn
on the ignition
as a check to show you it’s
working. If it doesn’t come
on then, have it fixed.

BI-LEV This setting brings in outside air and directs
it two ways. Half of the air is directed through the
instrument panel outlets. Most of the remaining air
is
directed through the floor ducts and a little to the defrost
and side window vents. The air conditioning compressor
will run automatically in this setting unless the outside
temperature is below
40°F (4°C).
VENT This setting brings in outside air and directs it
through the instrument panel outlets.
HTR: This setting sends most of the air through the
ducts near
the floor. The rest comes out of the defroster
and side window vents.
BLEND: This setting allows half of the air to go to the
floor ducts and half to the defroster and side window
vents. The air conditioning compressor will run
automatically in this setting unless the outside
temperature is below
40 OF (4 O C) .
FRONT This setting directs most of the air
through
the defroster and side window vents. Some of
the air also goes to the floor ducts. The air conditioning
compressor will run automatically
in this setting unless
the outside temperature is below
40°F (4°C).
Air Conditioning
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the time for the
vehicle to cool down.
For a quick cool-down on very hot days, use
MAX with
the temperature knob all the way in the blue area. If this
setting is used for long periods of time, the air
in your
vehicle may become too dry.
For normal cooling on hot days, use NORM with the
temperature knob in the blue area. The system will bring
in outside air and cool it.
On cool, but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use
BI-LEV and set the temperature knob to a
comfortable setting. The system will bring in outside air
and direct it
to your upper body, while sending slightly
warmed air to your lower body.
You may notice this
temperature difference more at some times than others.

Heating
On cold days, use HTR with the temperature knobs all
the way in the red area. The system will bring
in outside
air, heat it and send it to
the floor ducts.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it’s
cold outside
(0°F (-18°C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See “Engine Coolant
Heater” in
the Index.
Ventilation
For mild outside temperatures when little heating or
cooling is needed, use VENT to direct outside air through
your vehicle. Your vehicle also has the flow-through
ventilation system described later
in this section.
Defogging and Defrosting
Your system has two settings for clearing the front and side
windows.
To defrost the windows quickly, use FRONT.
For maximum defroster performance, set both
driver and passenger temperature controls to the
warmest setting.
To warm passengers while keeping the windows clear,
use
BLEND.
