engine is started, one of the engine's emission control systems may be
malfunctioning. The light may illuminate without a driveability concern
being noted. The vehicle will usually be drivable and will not require
towing.
What you should do if the check engine light illuminates
Light turns on solid:
This means that the OBD II system has detected a malfunction. Have
your vehicle serviced at your first opportunity.
Temporary malfunctions may also cause yourcheck enginelight to
illuminate. Examples follow:
²The vehicle has run out of fuel. (The engine may misfire or run
poorly.)
²Poor fuel quality or water in the fuel.
²The fuel cap may not have been securely tightened.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel and/or properly tightening the gas cap. After three
drive cycles without these or any other temporary malfunctions present,
thecheck enginelight should turn off.Novehicle service is required.
Light is blinking:
Engine misfire is occurring which could damage your catalytic converter.
You should drive in a moderate fashion (avoid heavy acceleration and
deceleration) and have your vehicle serviced at the first available
opportunity.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.
Air bag readiness
Briefly illuminates when the ignition
is turned on. If the light fails to
illuminate, continues to flash or
remains on, have the system
serviced immediately.

Automatic operation
Press AUTOMATIC and select the desired temperature. The selected
temperature and the word AUTO will appear in the display window. The
EATC system will either heat or cool to achieve the selected
temperature. The system will automatically determine fan speed, airflow
location and if fresh outside air or recirculated air is required. Fan speed
remains automatic unless the fan speed thumbwheel is turned.
When in AUTOMATIC and weather conditions require heat, air will be
sent to the floor. However, if the engine is not warm enough to provide
heat, the fan will be at a low speed and the air will be directed to the
windshield. In 3ó minutes or less, the fan speed will start to increase
and the airflow location will change to the floor area.
If unusual conditions exist (i.e.-window fogging, etc.), the manual
override controls allow you to select airflow locations and the fan control
allows you to adjust fan speed as necessary.
Temperature selection
The display window indicates the
selected temperature, function
(AUTO or one of the override
controls) and manual control of fan
speed (
) if automatic fan speed is
not desired.
To control the temperature, select
any temperature between 18ÉC
(65ÉF) and 29ÉC (85ÉF) by pressing
the blue (cooler) or red (warmer)
buttons.
For continuous maximum cooling, push the blue button until 16ÉC
(60ÉF) is shown in the display window. The EATC will continue
maximum cooling (disregarding the displayed temperature) until a
warmer temperature is selected by pressing the red button.

Manual override controls
The override controls are located at
the bottom of the EATC and allow
you to determine where airflow is
directed. To return to full automatic
control, press AUTOMATIC.
The air conditioning compressor will operate in all modes except FLOOR
and VENT. It will also operate only when required when AUTOMATIC
has been selected. However, the air conditioning will only function if the
outside temperature is about 10ÉC (50ÉF) or above.
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.
Under normal conditions, your vehicle's climate control system should be
left in any position other than MAX A/C or OFF when the vehicle is
parked. This allows the vehicle to ªbreatheº through the outside air inlet
duct.
²MAX A/C-Uses recirculated air to cool the vehicle. The temperature
will display 16ÉC (60ÉF). To exit, press AUTOMATIC or any other
override controls. MAX A/C is noisier than normal A/C but more
economical and will cool the inside of the vehicle faster. Airflow is
from the instrument panel registers. This mode can also be used to
prevent undesirable odors from entering the vehicle.
²VENT-Distributes outside air through the instrument panel registers.
However, the air cannot be cooled below the outside temperature
because the air conditioning does not operate in this mode.
²PNL²FLR-Distributes outside air through the instrument panel
registers and the floor ducts. Heating and air conditioning capabilities
are provided in this mode. The air will be heated or cooled based on
the temperature selection. For added customer comfort, the air
distributed through the floor ducts will be slightly warmer than the air
sent to the instrument panel registers.

²FLOOR-Allows for maximum heating by distributing outside air
through the floor ducts. However, the air cannot be cooled below the
outside temperature because the air conditioning does not operate in
this mode.
²FLR²DEF-Distributes outside air through the windshield defroster
ducts and the floor ducts. Heating and air conditioning capabilities are
provided in this mode. The air will be heated or cooled based on the
temperature selection. 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
10ÉC (50ÉF) or higher, the air conditioner will automatically
dehumidify the air to prevent fogging.
²DEF
-Distributes outside air through the windshield defroster
ducts. It can be used to clear ice or fog from the windshield. If the
outside air temperature is about 10ÉC (50ÉF) or higher, the air
conditioner will automatically dehumidify the air to prevent fogging.
²OFF-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.
Displaying outside temperature
Press OUTSIDE TEMP to display
the outside air temperature. It will
be displayed for four seconds.
If a manual override function is selected while the outside temperature is
displayed, the new function will be displayed for four seconds after it is
changed, then the outside temperature will return to the window along
with the override selection.
The outside temperature reading is most accurate when the vehicle is
moving. Higher readings may be obtained when the vehicle is not

moving. The readings that you get may not agree with temperatures
given on the radio due to differences in vehicle and station locations.
Operating tips
²In humid weather, select DEFbefore driving. This will prevent
your windshield from fogging. After a few minutes, select any desired
position.
²To prevent humidity buildup inside the vehicle, don't drive with the
climate control system in the OFF position.
²Don't put objects under the front seat that will interfere with the
airflow to the back seats.
²Remove any snow, ice or leaves
from the air intake area (at the
bottom of the windshield).
²If your vehicle has been parked with the windows closed during hot
weather, the air conditioner will do a much faster job of cooling if you
drive for two or three minutes with the windows open. This will force
most of the hot, stale air out of the vehicle. Then operate the air
conditioner as you would normally.
²When placing objects on top of your instrument panel, be careful to
not place them over the defroster outlets. These objects can block
airflow and reduce your ability to see through your windshield. Also,
avoid placing small objects on top of your instrument panel. These
objects can fall down into the defroster outlets and block airflow and
possibly damage your climate control system.

If the air bag is inflated,the air bag will not function again
and must be replaced immediately. If the air bag is not
replaced, the unrepaired area will increase the risk of injury in a
collision.
The SRS consists of:
²driver and passenger air bag modules (which include the inflators and
air bags),
²one or more impact and safing sensors,
²a readiness light and tone
²and the electrical wiring which connects the components.
The diagnostic module monitors its own internal circuits and the
supplemental air bag electrical system warning (including the impact
sensors), the system wiring, the air bag system readiness light, the air
bag back up power and the air bag ignitors.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer to theAir bag readiness
section in theInstrumentationchapter. Routine maintenance of the air
bag is not required.
A difficulty with the system is indicated by one or more of the following:
²The readiness light will either
flash or stay lit.
²The readiness light will not
illuminate immediately after
ignition is turned on.
²A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at your dealership or by a qualified technician immediately. Unless
serviced, the system may not function properly in the event of a
collision.

Guarding against exhaust fumes
Although odorless and colorless, carbon monoxide is present in exhaust
fumes. Take precautions to avoid its dangerous effects.
If you ever smell exhaust fumes of any kind inside your vehicle,
have your dealer inspect and fix your vehicle immediately. Do
not drive if you smell exhaust fumes. These fumes are harmful and
could kill you.
Have the exhaust and body ventilation systems checked whenever:
²the vehicle is raised for service.
²the sound of the exhaust system changes.
²the vehicle has been damaged in a collision.
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.

AIR SUSPENSION SYSTEM
The air suspension system is designed to improve ride, handling and
general vehicle performance during:
²certain road conditions
²steering maneuvers
²braking
²accelerations
This system maintains the vehicle height at a constant level by
automatically adding air or releasing air from the air springs to offset
changes in vehicle loads.
The air suspension shut-off switch is
located in the trunk. If this switch is
in the OFF position, the automatic
leveling system will not operate.
On vehicles equipped with
Air Suspension, turn OFF
the Air Suspension switch prior to
jacking, hoisting or towing your
vehicle.
Normal vehicle operation does not
require any action by the driver.
AUTOMATIC TRANSMISSION OPERATION
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift from being moved from P (Park) unless the brake pedal is
pressed.
If you cannot move the gearshift out of P (Park) with the brake pedal
depressed:

Driving while you tow
Do not drive faster than 88 km/h (55 mph) when towing a trailer.
Speed control may shut off if you are towing on long, steep grades.
When towing a trailer:
²Use a lower gear when towing up or down steep hills. This will
eliminate excessive downshifting and upshifting for optimum fuel
economy and transmission cooling.
²Anticipate stops and brake gradually.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to the Severe Duty Schedule in your
ªService Guideº for more information.
Trailer towing tips
²Practice turning, stopping and backing up in an area before starting on
a trip to get the feel of the vehicle trailer combination. When turning,
make wider turns so the trailer wheels will clear curbs and other
obstacles.
²Allow more distance for stopping with a trailer attached.
²The trailer tongue weight should be 10±15% of the loaded trailer
weight.
²After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
²When stopped in traffic for long periods of time in hot weather, place
the gearshift in P (Park) and increase idle speed. This aids engine
cooling and air conditioner efficiency.
²Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer's wheels.
FUEL CONSUMPTION
Fuel economy can be improved by avoiding:
²lack of regular, scheduled maintenance.
²excessive speed.
²rapid acceleration.
²extended idle.
