Downloaded from www.Manualslib.com manuals search engine Passenger's Side Temperature Knob
The right front passenger can control the temperature of
air for that area. (The passenger and driver knobs adjust
60 " F ( 16" C) to 90" F (32 " C) independent of each
other. It is suggested, however, that the passenger's
setting stay no more than four degrees warmer or cooler
in temperature from the driver's setting.) To turn the
system on, press the passenger's side TEMP button.
Turn the passenger's side TEMP knob to the right to
increase the temperature and to the left to decrease the
temperature. Press the passenger's side TEMP knob
again to turn off the passenger's side system. If the
passenger's side is turned
off, the driver's side will
control the temperature of the entire vehicle.
Automatic Operation
When the system is set for automatic operation, sensors
will control the air delivery mode. Air will come from
the floor, the instrument panel or windshield outlets. The
fan speed will vary as the system maintains the selected
temperature setting.
Be careful not to put anything over the electronic solar sensors located near the ends
of the instrument panel
near the windshield. These sensors are used by the
automatic system to regulate temperature. To
find your comfort zone, start with the
75°F (24°C)
setting and allow about 30 minutes for the system to
regulate. Turn the TEMP knob to adjust the temperature
if necessary. If
you choose 60°F (16"C), the system
will remain at that maximum cooling setting and will
not regulate fan speed. If you choose
90°F (32"C), the
system will remain at that maximum heating setting
and will not regulate fan speed. Choosing either
maximum setting will not cause the system to heat
or cool any faster.
With the automatic setting, the air conditioning
compressor cycles when needed to cool the air. In cold
weather, when the system senses the need for heat, the
airflow will be directed out the floor outlets.
As the
interior temperature approaches a desired setting, the
blower speed will decrease.
To maintain interior
comfort, the airflow may move
to the instrument panel
air outlets and floor outlets (bi-level mode). On bright
sunny days
in cold weather, the aifflow may come out
of the air conditioning outlets
(AX mode) to maintain
comfort and prevent stuffiness.

Downloaded from www.Manualslib.com manuals search engine If your vehicle is sitting out on a hot day and you have it
set on
AUTO, the air will first flow out the floor outlets
for a few seconds. This is normal. This is to remove hot
air from the air outlets.
As the air is cooled, the airflow
will move through the air conditioning outlets.
To avoid blowing cold air in cold weather, the system
will start at reduced fan speeds until warm air is
available. The length of reduction depends on the
outside air temperature, engine coolant temperature
or the time since the engine was last started.
As the
coolant warms up, the blower fan speed will gradually
increase and air will flow from the heater outlets, with
some airflow to the windshield to prevent fogging under
most normal conditions. If you select defrost mode or a
manual fan speed, this function will be skipped.
If you leave your vehicle, the system will remember
the control setting the next time you start your engine,
except for recirculation and defrost. Each ignition
cycle cancels recirculation. Defrost will change to
automatic operation when the ignition is shut
off and
then turned back on.
Electronic Solar Sensor Electronic Solar Sensor
The sensor monitors the sun’s solar radiation and is
located near the end of the instrument panel near
the windshield.
The climate control panel uses this information to
automatically make
the necessary temperature and
airflow adjustments to maintain your comfort. The
climate control system may supply cooler air to one side
of your vehicle, if that side is facing the sun. Be careful
not to put anything over the sensor on top
of the dash.

The air cleaner is located next to the coolant surge tank
on the driver’s side of the engine. Be sure the engine has
cooled before following
these steps to replace the air
cleaner filter:
2. With a screwdriver,
loosen the air duct
clamp, which is located
at the mass airflow
sensor end of the
air duct.
1. Disconnect the Intake
Air Temperature
(IAT)
sensor from the clean
air duct
.
3. Disconnect the air duct from the mass airflow sensor.

Downloaded from www.Manualslib.com manuals search engine Follow these steps to reinstall the air cleaner assembly:
1.
2.
3.
4.
5.
Slide the air cleaner lid into the slots in the bottom of
the air cleaner base.
Close the cover and make sure that both latches are
secure and fully engaged.
Reinstall the clean air duct over the mass airflow
sensor. Make sure that the duct is secure around the
entire outer edge of the sensor.
Tighten the air duct clamp. Reconnect the
MI’ sensor.
Refer to the Maintenance Schedule
to determine when to
replace the air filter.
See “Scheduled Maintenance Services” in the
Maintenance Schedule booklet.
’ A ( JTION:
Operating the engine with the air cleaner off can
cause you or others to be burned, The
air cleaner
not only cleans the
air, it stops flame if the engine
backfires.
If it isn’t there, and the engine
backfires, you could be burned. Don’t drive with
it
off, and be careful working on the engine with
the air cleaner off.
I NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage it. Always
have the air cleaner in place when you’re driving.

Downloaded from www.Manualslib.com manuals search engine Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make
a high-pitched warning sound when the brake pads are
worn and new pads are needed. The sound may come
and
go or be heard all the time your vehicle is moving
(except when you are pushing on the brake
pedal firmly).
r
A CAUTION:
The brake wear warning sound means that soon
your brakes won’t work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
Your vehicle also has electronic wear sensors that let you
know when the brake pads are significantly worn and new
pads are needed. The
CHANGE BRAKE PADS message
will be displayed on the Driver
Information Center when
the brake pads are worn and need
to be replaced. (See
“Change Brake Pads Message” in the Index.)
-
I A CAUTION:
\-I
The CHANGE BRAKE PADS message or the
high-pitched warning sound means that soon
your brakes won’t work well. That could lead to
an accident. When the
CHANGE BRAKE PADS
message comes on and stays on, have your
vehicle serviced.
