Climate Control Functions
A/C (Air Conditioning)
The Air Conditioning (A/C) button allows the
operator to manually activate or deactivate
the air conditioning system. When the air
conditioning system is turned on, cool dehu-
midified air will flow through the outlets into
the cabin. For improved fuel economy, press
the A/C button to turn off the air conditioning
and manually adjust the blower and airflow
mode settings. Also, make sure to select only
Panel, Bi-Level, or Floor modes.
NOTE:
• If fog or mist appears on the windshield or
side glass, select Defrost mode and in-
crease blower speed if needed.
• If your air conditioning performance seems
lower than expected, check the front of the
A/C condenser (located in front of the ra-
diator), for an accumulation of dirt or in-
sects. Clean with a gentle water spray from
the front of the radiator and through the
condenser.MAX A/C
MAX A/C sets the control for maximum cool-
ing performance. Press and release to toggle
between MAX A/C and the prior settings. The
button illuminates when MAX A/C is ON.
Pressing blower speed, temperature, recircu-
lation, or mode settings, will cause the MAX
A/C operation to switch to the selected set-
ting and MAX A/C to exit.
Recirculation
When outside air contains smoke, odors, or
high humidity, or if rapid cooling is desired,
you may wish to recirculate interior air by
pressing the Recirculation control button.
The Recirculation indicator will illuminate
when this button is selected. Press the but-
ton a second time to turn off the Recircula-
tion mode and allow outside air into the
vehicle.NOTE:
In cold weather, use of Recirculation mode
may lead to excessive window fogging. The
Recirculation feature may be unavailable

matic transmission into PARK (manual
transmission in NEUTRAL) and turn the
ignition to OFF/LOCK.
2. Turn off the heater, radio, and all unnec-
essary electrical accessories.
3. If using another vehicle to jump start the
battery, park the vehicle within the
jumper cables reach, set the parking
brake and make sure the ignition is
OFF/LOCK.
WARNING!
Do not allow vehicles to touch each other
as this could establish a ground connec-
tion and personal injury could result.

IF YOUR ENGINE
OVERHEATS
In any of the following situations, you can
reduce the potential for overheating your en-
gine by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the
transmission in NEUTRAL, but do not in-
crease engine idle speed.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads “H,” pull over and stop the
vehicle. Idle the vehicle with the air con-
ditioner turned off until the pointer drops
back into the normal range. If the pointer
remains on the “H” and you hear continu-
ous chimes, turn the engine off immedi-
ately and call for service.NOTE:
There are steps that you can take to slow
down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off.
The A/C system adds heat to the engine
cooling system and turning the A/C off can
help remove this heat.
• You can also turn the temperature control
to maximum heat, the mode control to floor
and the blower control to high. This allows
the heater core to act as a supplement to
the radiator and aids in removing heat from
the engine cooling system.WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open
the hood until the radiator has had time to
cool. Never try to open a cooling system
pressure cap when the radiator or coolant
bottle is hot.
GEAR SELECTOR OVERRIDE
If a malfunction occurs, and the gear selector
cannot be moved out of the PARK position,
you can use the following procedure to tem-
porarily move the gear selector:
1. Turn the engine OFF.
2. Apply the park brake.
3. Grasp the boot material rearward of the
gear selector and pull up to carefully
separate the gear selector bezel and boot
assembly from the center console.

Checking Oil Level
To assure proper engine lubrication, the en-
gine oil must be maintained at the correct
level. Check the oil level at regular intervals,
such as once a month or before a long trip.
The best time to check the engine oil level is
approximately five minutes after a fully
warmed engine is shut off. Do not check oil
level before starting the engine after it has sat
overnight. Checking engine oil level when the
engine is cold will give you an incorrect read-
ing.
Checking the oil while the vehicle is on level
ground, and approximately five minutes after
a fully warmed engine is shut off, will improve
the accuracy of the oil level readings. Main-
tain the oil level between the range markings
on the dipstick. The safe range is indicated
by a crosshatch zone. Adding 1 quart (0.9 Li-
ters) of oil when the reading is at the low end
of the indicated range will result in the oil
level at the full end of the indicator range.
CAUTION!
• Overfilling or underfilling will cause oil
aeration, or loss of oil pressure. This
could damage your engine.
• Never use Non-Detergent Oil or Straight
Mineral Oil in the engine or damage may
result.
Adding Washer Fluid
The fluid reservoir is located in the front of
the engine compartment. Be sure to check
the fluid level in the reservoir at regular
intervals. Fill the reservoir with windshield
washer solvent (not radiator antifreeze) and
operate the system for a few seconds to flush
out the residual washer fluid.
When refilling the washer fluid reservoir, take
some washer fluid, apply it to a cloth or towel,
and wipe clean the wiper blades; this will
help blade performance.To prevent freeze-up of your windshield
washer system in cold weather, select a solu-
tion or mixture that meets or exceeds the
temperature range of your climate. This rat-
ing information can be found on most washer
fluid containers.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite
and burn you. Care must be exercised
when filling or working around the washer
solution.
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-
free battery. You will never have to add water,
nor is periodic maintenance required.
WARNING!
• Battery fluid is a corrosive acid solution
and can burn or even blind you. Do not
allow battery fluid to contact your eyes,
skin, or clothing. Do not lean over a
battery when attaching clamps. If acid

WARNING!
mable and can explode, injuring you.
Other unapproved refrigerants or lubri-
cants can cause the system to fail, re-
quiring costly repairs. Refer to Warranty
Information Book, located in your own-
er’s information kit, for further warranty
information.
• The air conditioning system contains re-
frigerant under high pressure. To avoid
risk of personal injury or damage to the
system, adding refrigerant or any repair
requiring lines to be disconnected
should be done by an experienced tech-
nician.
CAUTION!
Do not use chemical flushes in your air
conditioning system as the chemicals can
damage your air conditioning components.
Such damage is not covered by the New
Vehicle Limited Warranty.

See your authorized dealer for service.
Wiper Blades
Clean the rubber edges of the wiper blades
and the windshield and rear window periodi-
cally with a sponge or soft cloth and a mild
nonabrasive cleaner. This will remove accu-
mulations of salt, waxes, or road film, and
help reduce streaking and smearing.
Operation of the wipers on dry glass for long
periods may cause deterioration of the wiper
blades. Always use washer fluid when using
the wipers to remove salt or dirt from a dry
windshield or rear window.
Avoid using the wiper blades to remove frost
or ice from the windshield or rear window.
Make sure that they are not frozen to the glass
before turning them on to avoid damaging the
blade. Keep the wiper blade out of contact
with petroleum products such as engine oil,
gasoline, etc.NOTE:
Life expectancy of wiper blades varies de-
pending on geographical area and frequency
of use. Poor performance of blades may be
present with chattering, marks, water lines or
wet spots. If any of these conditions are
present, clean the wiper blades or replace as
necessary.
Cooling System
WARNING!
• You or others can be badly burned by hot
engine coolant (antifreeze) or steam
from your radiator. If you see or hear
steam coming from under the hood, do
not open the hood until the radiator has
had time to cool. Never open a cooling
system pressure cap when the radiator or
coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts auto-
matically and may start at any time,
whether the engine is running or not.
235

WARNING!
• When working near the radiator cooling
fan, disconnect the fan motor lead or
turn the ignition to the OFF mode. The
fan is temperature controlled and can
start at any time the ignition is in the ON
mode.
Coolant Checks
Check engine coolant (antifreeze) protection
every 12 months (before the onset of freezing
weather, where applicable). If the engine
coolant (antifreeze) is dirty or rusty in appear-
ance, the system should be drained, flushed
and refilled with fresh engine coolant (anti-
freeze). Check the front of the A/C condenser
for any accumulation of bugs, leaves, etc. If
dirty, clean by gently spraying water from a
garden hose vertically down the face of the
condenser.
Brake System
In order to assure brake system performance,
all brake system components should be in-
spected periodically. Refer to the “Mainte-
nance Plan” in this section for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your
foot resting or riding on the brake pedal
can result in abnormally high brake tem-
peratures, excessive lining wear, and pos-
sible brake damage. You would not have
your full braking capacity in an emergency.
Brake Master Cylinder
The fluid in the master cylinder should be
checked when performing under hood ser-
vices or immediately if the “Brake Warning
Light” is illuminated.
Be sure to clean the top of the master cylin-
der area before removing the cap. If neces-
sary, add fluid to bring the fluid level up to
the requirements described on the brakefluid reservoir. With disc brakes, fluid level
can be expected to fall as the brake pads
wear. Brake fluid level should be checked
when pads are replaced. However, low fluid
level may be caused by a leak and a checkup
may be needed.
Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubricants”
in “Technical Specifications” for further
information.
WARNING!
• Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubri-
cants” in “Technical Specifications” for
further information. Using the wrong
type of brake fluid can severely damage
your brake system and/or impair its per-
formance. The proper type of brake fluid
for your vehicle is also identified on the
original factory installed hydraulic mas-
ter cylinder reservoir.
• To avoid contamination from foreign
matter or moisture, use only new brake
fluid or fluid that has been in a tightly
