Controls the direction of the airflow
to the inside of the vehicle.
The air conditioning compressor can operate in all modes exceptand
. However, the air conditioning will only function if the outside
temperature is about 6°C (43°F) or higher.
Since the air conditioner removes considerable moisture from the air
during operation, it is normal if clear water drips on the ground under
the air conditioner drain while the system is working and even after you
have stopped the vehicle.
•MAX A/C – Uses recirculated air to cool the vehicle. MAX A/C is
noisier than A/C but more economical and will cool the inside of the
vehicle faster. Airflow will be from the instrument panel registers. This
mode can also be used to prevent undesirable odors from entering the
vehicle.

(Panel) – Distributes outside air through the instrument panel
registers. However, the air will not be cooled below the outside
temperature because the air conditioning does not operate in this
mode.
•OFF – Outside air is shut out and the fan will not operate. For short
periods of time only, use this mode to prevent undesirable odors from
entering the vehicle.
•(Panel and floor) – Distributes outside air through the
instrument panel registers and the floor ducts. Heating and air
conditioning capabilities are provided in this mode. For added
customer comfort, when the temperature control knob is anywhere in
between the full hot and full cold positions, the air distributed through
the floor ducts will be slightly warmer than the air sent to the
instrument panel registers.
•(Floor) – Distributes outside air through the floor ducts.
However, the air will not be cooled below the outside temperature
because the air conditioning does not operate in this mode.
•(Floor and defrost) – Distributes outside air through the

conditioning capabilities are provided in this mode. For added
customer comfort, the air distributed through the floor ducts will be
slightly warmer than the air sent to the windshield defroster ducts. If
the temperature is about 6°C (43°F) or higher, the air conditioner will
automatically dehumidify the air to reduce fogging.
•(Defrost) – Distributes outside air through the windshield
defroster ducts. It can be used to clear ice or fog from the windshield.
If the temperature is about 6°C (43°F) or higher, the air conditioner
will automatically dehumidify the air to reduce fogging.
Operating tips
•In humid weather conditions, place the climate control system in
Defrost mode before driving. This will reduce fogging on your
windshield. Once the windshield has been cleared, operate the climate
control system as desired.
•To reduce humidity buildup inside the vehicle in cold weather
conditions, don’t drive with the climate control system in the OFF or
MAX A/C position.
•To reduce humidity buildup inside the vehicle in warm weather
conditions, don’t drive with the climate control system in the OFF

The compass reading may be affected when you drive near large
buildings, bridges, power lines and powerful broadcast antenna. Magnetic
or metallic objects placed in or on the vehicle may also affect compass
accuracy. Adjustments may need to be made to the zone and calibration
of the compass.
Compass zone adjustment
1. Determine which magnetic zone
you are in for your geographic
location by referring to the zone
map.
2. Locate the trip computer on the
overhead console.
3. Turn ignition to the ON position.
4. Press and hold both trip
computer controls. After
approximately four seconds, the trip
computer will enter zone setting
mode. Zone setting mode is
indicated when the display lights the
“ZONE” indicator.
5. Release both controls.
Subsequent pressing of either
control will increment the zone.
Press the control repeatedly until
the correct zone setting for your geographic location is displayed on the
trip computer.
6. To exit the zone setting mode and save the displayed zone in memory,
release both controls for greater than five seconds.
Compass calibration adjustment
Perform this adjustment in an open area free from steel structures and
high voltage lines.
For optimum calibration, turn off all electrical accessories (heater/air
conditioning, wipers, etc.) and make sure all vehicle doors are shut.

Have the exhaust and body ventilation systems checked whenever:
•the vehicle is raised for service.
•the sound of the exhaust system changes.
•the vehicle has been damaged in a collision.
WARNING:Engine exhaust, some of its constituents, and
certain vehicle components contain or emit chemicals known to
the State of California to cause cancer and birth defects or other
reproductive harm. In addition, certain fluids contained in vehicles and
certain products of component wear contain or emit chemicals known
to the State of California to cause cancer and birth defects or other
reproductive harm.
Important ventilating information
If the engine is idling while the vehicle is stopped in an open area for
long periods of time, open the windows at least 2.5 cm (one inch).
Adjust the heating or air conditioning (if equipped) to bring in fresh air.
Improve vehicle ventilation by keeping all air inlet vents clear of snow,
leaves and other debris.
BRAKES
Your service brakes are self-adjusting. Refer to the scheduled
maintenance guide for scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle’s brake system. In normal
operation, automotive brake systems may emit occasional or intermittent
squeal or groan noises when the brakes are applied. Such noises are
usually heard during the first few brake applications in the morning;
however, they may be heard at any time while braking and can be
aggravated by environmental conditions such as cold, heat, moisture,
road dust, salt or mud. If a “metal-to-metal,” “continuous grinding” or
“continuous squeal” sound is present while braking, the brake linings
may be worn-out and should be inspected by a qualified service
technician.If you are driving down a long or steep hill, shift to a lower gear.
Do not apply your brakes continuously, as they may overheat
and become less effective.

•Decreased engine coolant concentrations below 40% will
decrease the corrosion protection characteristics of the engine
coolant and may cause engine damage.
•Decreased engine coolant concentrations below 40% will
decrease the freeze protection characteristics of the engine
coolant and may cause engine damage.
•Refer to the chart on the coolant container to ensure the
coolant concentration in your vehicle will provide adequate
protection at the temperatures in which you drive.
Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.
What you should know about fail-safe cooling (if equipped)
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The “fail-safe” distance depends on ambient temperatures, vehicle load
and terrain.
How fail-safe cooling works
If the engine begins to overheat:
•The engine coolant temperature
gauge will move to the red (hot)
area.
•The
and
symbol will
illuminate.
•TheService Engine Soon
indicator light will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When this occurs the vehicle will still operate. However:
•The engine power will be limited.
•The air conditioning system will be disabled.
Continued operation will increase the engine temperature and the engine
will completely shut down, causing steering and braking effort to
increase.
Once the engine temperature cools, the engine can be re-started. Take
your vehicle to a service facility as soon as possible to minimize engine
damage.

How fail-safe cooling works
If the engine begins to overheat:
•The engine coolant temperature
gauge will move to the red (hot)
area.
•The
and
symbol will
illuminate.
•TheService Engine Soon
indicator light will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When this occurs the vehicle will still operate. However:
•The engine power will be limited.
•The air conditioning system will be disabled.
Continued operation will increase the engine temperature and the engine
will completely shut down, causing steering and braking effort to
increase.
Once the engine temperature cools, the engine can be re-started. Take
your vehicle to a service facility as soon as possible to minimize engine
damage.
