Mode Buttons
VENT: The VENT button allows outside air to flow
through your vehicle without the air conditioning
compressor working. Selecting the VENT and AUTO
buttons at the same time allows the system to control the
air flow automatically without using the air conditioning
compressor or the recirculation mode. To turn off the
VENT selection, press the VENT button again.
RECIRC (Recirculation): When RECIRC is selected,
the system will limit the amount of outside air entering
your vehicle. This is helpful when you are trying to cool
the interior of the vehicle quickly or limit the amount of
outside air entering your vehicle for some other reason.
RECIRC and AUTO may be selected at the same time.
The system will remain in recirculation until the ignition
is turned off. The system will return to the previously
selected mode when the car is restarted. RECIRC can be
selected in all manual airflow modes except FRONT
defrost and VENT.
FRONT: This selection is used to defrost
the windshield by directing the airflow toward
the windshield.If FRONT is selected while in the AUTO mode, the fan
speed and the air temperature coming from the front
defroster will vary. If a manual fan speed is selected, it
will remain until another fan speed or the AUTO mode
are selected. To turn off FRONT, press the AUTO or
AIR FLOW button.
FRONT defrost will work better if ice or snow is cleared
from the hood and the air inlet area, located between the
base of the windshield and the hood.
OFF: If the passenger comfort control is turned on,
it can be turned off by pressing the OFF button once.
Pressing the OFF button a second time will turn off the
main system. Turning off the main system causes the fan
to turn off and the airflow to be directed to the floor. The
system will still try to keep the interior of the vehicle at
the previously chosen temperature setting. The outside
temperature will be shown on the display when the
system is off.
The ventilation system always allows outside air to flow
through your vehicle when the vehicle is moving, even
with the system in the OFF mode.

AUTO (Automatic Climate Control): Press the AUTO
button when you want the system to automatically
maintain a set temperature. When the system is set for
automatic operation, air will come from the floor ducts,
instrument panel outlets or windshield outlets depending
on the temperature inside the vehicle, the outside
temperature and the sun load. Sun and temperature
sensors automatically adjust the air temperature, the
airflow direction and the fan speed to maintain your
comfort setting. The system may supply cooler air to the
side of the vehicle toward the sun. Be careful not to put
anything over the sensors on top of the dash.
To find your preferred temperature setting, start with the
system in AUTO mode and the temperature set at 75
F
(24
C). Give the vehicle about 20 minutes to stabilize,
and adjust your the temperature setting, if necessary,
using the TEMP button. The display will show the
selected temperature, fan speed and airflow direction for
a few seconds, and then it will display the outside
temperature. If you choose a temperature setting of 60
F
(15
C), the system will remain at the maximum cooling
setting and fan speed. If you choose a temperature
setting of 90
F (33
C), the system will remain at the
maximum heat setting and fan speed. Choosing either
maximum setting will not cause the system to heat or
cool any faster.In cold weather, the system will delay turning the fan
on high, to avoid blowing cold air into the vehicle. The
length of the delay depends on the engine coolant
temperature and the outside temperature. Pressing the
FAN, AIR FLOW or FRONT buttons will override
this delay, turn off the AUTO setting and change the
fan speed.
Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
On very hot days, the automatic system will enter the
recirculation mode and the temperature door will be
positioned at the full cold position for maximum cooling
for as long as necessary to reach the set temperature.
You can choose the extreme temperature setting of
60
F (15
C), but the system will not cool any faster.

7-36 Fuel System Inspection
Inspect the complete fuel system for damage or leaks.
Engine Cooling System Inspection
Inspect the hoses and have them replaced if they are
cracked, swollen or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed. Clean the outside
of the radiator and air conditioning condenser. To help
ensure proper operation, a pressure test of the cooling
system and pressure cap is recommended at least once
a year.
Throttle System Inspection
Inspect the throttle system for interference or binding,
and for damaged or missing parts. Replace parts as
needed. Replace any components that have high effort
or excessive wear. Do not lubricate accelerator and
cruise control cables.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook
-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear and rotors
for surface condition. Inspect other brake parts,
including calipers, parking brake, etc. Check parking
brake adjustment. You may need to have your brakes
inspected more often if your driving habits or conditions
result in frequent braking.
