If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work
as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running.
If the light doesn’t come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
0 Light Flashing -- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis and service may be required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and service may be required.
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.
0 If you are towing a trailer, reduce the amount of
cargo being hauled
as soon as it is possible.
If the light stops flashing and remains on steady, see “If
the Light
Is On Steady’’ following.
If the light continues to flash, 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 flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.

Downloaded from www.Manualslib.com manuals search engine If the Light Is On Steady Have you recentIy changed brands of fuel?
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. 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.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly.
It
will take a few driving trips to turn the light off. If
so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). 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, misfiring, 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.
If you experience one or more of these conditions,
change the fuel brand you use.
It will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn
off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical
or electrical
problems that may have developed.

The red and blue temperature buttons adjust the air
temperature coming through the system. Press the
blue button for a cooler setting or the red button for a
warmer setting.
Passenger’s Side Temperature Knob
With this feature, the right front passenger can control
the temperature of air for hisher own zone. The
passenger can select a four degree warmer or cooler
temperature from the driver’s setting.
To turn the system on, press the knob on the passenger’s
side armrest. Rotate the knob to the right to increase
the temperature and turn to the left to decrease the
temperature. Press the knob again to turn the system
off.
Outside Temperature Display
The outside temperature is always displayed when your
vehicle is running. You can change it from Fahrenheit to
Celsius by pressing the ENG/MET (EnglisWmetric)
button on the Driver Information Center (DIC).
The outside temperature sensor is located near the
front grille. The sensor can be affected by road or
engine heat during idling, slow driving or when the engine
is first started after a
short trip. In order to ensure
proper automatic climate control operation, the outside
air temperature display may not update as quickly as
expected. This is to allow the air surrounding the outside
temperature sensor to be as close to the actual outside
conditions as possible. This is determined by how much
time has elapsed since the vehicle has been turned
off
and by vehicle speed.
Mode Controls
The AUTOECON button automatically controls the
direction
of air delivery for air conditioning and non-air
conditioning modes.
Automatic Operation
When the system is set for automatic operation, sensors
will control the air delivery mode. Air will come from
the floor, middle or windshield outlets. The fan speed
will
vary as the system maintains the selected
temperature setting.
Be careful not to put anything over the solar sensor
located in the middle of the instrument panel near the
windshield. This sensor is used by the automatic system
to regulate temperature.
Page 171 of 386
Downloaded from www.Manualslib.com manuals search engine To find your comfort zone, start with the 75 "F (24°C)
setting and allow about 30 minutes for the system to
regulate. Press the red or blue temperature buttons
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 the temperature of
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 automatically 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 airflow may come
out of the air conditioning outlets
(AC mode) to
maintain comfort and prevent stuffiness. 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 air
outlets for a few seconds. That is normal.
This is to
expel hot air from the air outlets.
As the air is cooled,
the airflow will move through the air conditioning
outlets. If you start your vehicle with the
fan setting on
HI, it will
skip the air conditioning purge.
To avoid blowing cold
air in cold weather, the system will
delay turning on the fan until warm air is available. The
length of delay depends on the outside air temperature,
engine coolant temperature or the time since the engine
was last started.
As the coolant warrns 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 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, whereas, DEFROST will change
to automatic operation when the ignition is shut off and
then turned back on.

0 RECIRCULATION: Press this button to limit the
amount of fresh
air entering your vehicle. This is helpful
when you
are trying to cool the air quickly or limit
odors entering your vehicle. In the AUTO mode, the
system will use recirculation as necessary to cool the
air. Pressing the recirculation button will change the
operation to a manual mode and the
air will recirculate
non-stop. Press this button again to turn off the
recirculation feature.
If you notice the windows fogging, press the
recirculation button to exit the recirculation mode.
OFF: Press this button to turn the system off. Fresh
air will continue to flow through the vehicle, and
the system will try to maintain the previously set
temperature. The outside temperature will show in
the display when the system
is off.
DEFOG: Press this button to divide the air between the
windshield and the heater outlets. This is useful when
fog appears on the windshield or side glass due to
sudden rain or snowy conditions.
AUTOECON: Press this button to switch between
AUTO and
ECON. The ECON setting attempts to keep
air at a selected temperature, however, it does not remove
humidity from the
air. Use this setting in cold or cool weather to save fuel. The AUTO setting is used when
it’s warm outside and you need
to cool the air in order to
maintain
a selected temperature and blower speed.
FAN SPEEDS: Press the button with the fan symbol
on it until AUTO is displayed on the screen. At this
setting, the fan speed is automatically controlled. If
it is
cold outside, the blower may not run in the maximum
high fan speed right away. The system checks the
temperature of the engine coolant to assure it is warm
enough to provide heat. When the engine coolant is
warm, the controller allows the fan to gradually increase
.
to a higher speed. This prevents cold air from blowing
into the passenger compartment.
If you want the blower
fan at a high speed, press the up arrow button until you
see HI on the display. If you want the fan speed to be
automatic, but you like the
fan speed to be higher than
the AUTO setting, press the fan symbol button until
HI
AUTO is shown on the display. If you want the blower
fan at a low speed, press the down arrow button until LO
is shown on the display. If you want the fan speed to run
lower than the AUTO setting, press the button until
AUTO
LO is shown on the display.
DEFROST Press this button to quickly remove
fog or frost from the windshield. This setting sends
most of the airflow to the windshield with only a
small amount to the floor outlets.
