Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Turn the right knob clockwise or counterclockwise to
direct the airow inside of your vehicle.To change the current mode, select one of the following:
)(Bi-Level):This mode directs approximately half
of the air to the instrument panel outlets and directs
most of the remaining air to the oor outlets. Some air
may be directed toward the windshield.
H(Vent):This mode directs air to the instrument
panel outlets.
6(Floor):This mode directs most of the air to the
oor outlets with some air directed to the outboard
outlets (for the side windows) and some air directed to
the windshield.
A/C (Air Conditioning):This setting brings in outside
air, cools and dehumidies it.
MAX A/C (Maximum Air Conditioning):This setting
cools the air the fastest, by recirculating the inside air.
The right knob can also be used to select the defrost
mode. Information on defogging and defrosting can be
found later in this section.

Defogging and Defrosting
Turn the right knob to select the defog or defrost mode.
-(Blend):With this setting, the outside air comes
out of both the oor and defroster outlets. Adjust
the temperature knob for warmer or cooler air. The air
conditioning compressor may operate in this setting
to dehumidfy the air.
1(Defrost):This setting operates the defroster. Most
of the air comes out near the windshield, with some
going to the oor outlets and front side windows. The air
conditioning compressor may operate in this setting to
dehumidify the air.
The bi-level setting is useful for cold weather with a
large number of passengers or very humid conditions to
help keep the windshield clear. Use defrost to remove
fog or ice from the windshield quickly in extremely
cold conditions. The temperature knob should be in the
red area and the fan control toward high.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
ignition is in RUN.Press this button to turn
the rear window defogger
on or off. Be sure to
clear as much snow from
the window as possible.
The rear window defogger will turn off several minutes
after the button is pressed. If turned on again, the
defogger will run for several more minutes before turning
off. The defogger can also be turned off by pressing
the button again or by turning off the engine.
Notice:Using a razor blade or sharp object to clear
the inside rear window may damage the rear
window defogger. Repairs would not be covered by
your warranty. Do not clear the inside of the rear
window with sharp objects.

If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.
This light should come on
briey when you turn the
ignition key to RUN. If
it doesn’t come on then,
have it xed so it will
be ready to warn you if
there’s a problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the
oor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeTowing
Your Vehicle on page 4-29.
{CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you
have pulled off the road and stopped carefully,
have the vehicle towed for service.
Anti-Lock Brake System
Warning Light
With the anti-lock brake system, this light will come on
when you start your engine and may stay on for
several seconds. That’s normal.
If the light stays on, or comes on when you’re driving,
your vehicle needs service. If the regular brake system
warning light isn’t on, you still have brakes, but you don’t
have anti-lock brakes. If the regular brake system
warning light is also on, you don’t have anti-lock brakes
and there’s a problem with your regular brakes. See
“Brake System Warning Light” earlier in this section.
The anti-lock brake system warning light should come
on briey when you turn the ignition key to RUN. If
the light doesn’t come on then, have it xed so it will be
ready to warn you if there is a problem.

If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
Avoiding hard accelerations.
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 ashing and remains on steady, see “If
the Light Is On Steady” following.
If the light continues to ash, 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
ashing, follow the previous steps, and see your dealer
for service as soon as possible.
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. SeeFilling Your Tank on page 5-7. 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.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-4. 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, misring, hesitation
on acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the
light to turn on.

Tow/Haul Mode Light
This light should come on
when the tow/haul mode
has been selected.
For more information, see “Tow/Haul Mode” inTowing a
Trailer on page 4-35.
Check Gages Warning Light
The CHECK GAGES light
will come on briey 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.
Fuel Gage
The fuel gage tells you approximately how much fuel
you have remaining when the ignition is on.
When the gage rst indicates empty, you still have a
little fuel left, but you should get more fuel as soon
as possible.
