The system will automatically control re-
circulation. However, pressing this but-
ton will temporarily put the system in
“Recirculation” mode. This can be used
when outside conditions such as smoke,
odors, dust, or high humidity are present. This will cause
the LED to illuminate.
NOTE:
•The surface of the climate control panel, and the top
center of the instrument panel should be kept free of
debris due to the climate control sensor’s location.
Mud on the windshield may also cause poor operation
of this system.
•To provide you with maximum comfort in the auto-
matic mode, during cold start-ups the blower fan will
remain off until the engine warms up. However, the
fan will engage immediately if the defrost mode is
selected or if you manually select a blower speed.
•Under certain conditions (after the vehicle is turned
off) the climate control system may recalibrate and a
noise may be heard for 20 seconds. This is part of
normal operation.
•Most of the time, when in Automatic operation, you
can temporarily put the system into Recirculation
mode by pressing the “Recirculation” button. How-
ever, under certain conditions in automatic the system
is blowing air out of the defrost vents. When these
conditions are present, and the “Recirculation” button
is pressed, the indicator will flash and remain off. This
tells you that you are unable to go into Recirculation
mode at this time. If you would like to go to Recircu-
lation mode, you must first move your mode knob to
Panel, Panel/Floor, or Floor, then press the “Recircu-
lation” button. This feature will reduce the possibility
of window fogging.

captured interior air to condense on windows and ham-
per visibility. For this reason, the system will not allow
“Recirculation” mode to be selected while in the defrost
or defrost/floor modes. Attempting to use Recirculation
while in these modes will cause the LED in the button to
blink and then turn off.
Operating Tips
Window Fogging
Windows will fog on the inside when the humidity inside
the vehicle is high. This often occurs in mild or cool
temperatures when it’s rainy or humid. In most cases,
turning the air conditioning (pressing the snowflake
button) on will clear the fog. Adjust the temperature
control, air direction, and blower speed to maintain
comfort.
As the temperature gets colder, it may be necessary to
direct air onto the windshield. Adjust the temperature
control and blower speed to maintain comfort. Higherblower speeds will reduce fogging. Interior fogging on
the windshield can be quickly removed by selecting the
defrost mode.
Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant, during the summer, to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended. Refer to Recommended
Fluids and Genuine Parts for the proper coolant type.
When using the air conditioner in extremely heavy
traffic, in hot weather, especially when towing a trailer,

Operation
By placing the shift lever in the DRIVE position, the shift
lever can be moved from side to side. This allows the
driver to engage the AutoStickmode. Moving the shift
lever to the right (+) or the left (-) will engage the
AutoStick mode. In normal driving mode (Boxed “D”
displayed in the PRNDL), moving the shift lever to the
right (+) will engage the AutoStick mode putting the
transmission in the currently engaged gear. Moving the
shift lever to the Left (-) will engage the AutoStick mode
and downshift the transmission one gear. For example, if
the transmission is in Drive mode (a boxed Dis
displayed in the cluster) and is operating in third gear,
tapping the shift lever to the right (+) will engage
AutoStick mode (while remaining in third gear) and a
boxed 3will be displayed in the cluster. Tapping the
shift lever to the left (-) would also engage AutoStick 
mode, but would force a downshift to second gear, and display a boxed
2in the cluster. Once AutoStick mode
is engaged, a move to the right (+) or left (-) will trigger
a upshift (+) or trigger a downshift (-).
NOTE: In the AutoStick mode, the transmission will
shift up and down when left or right (D-/D+) is manu-
ally selected by the driver.
The transmission will not allow a downshift if the
downshift would result in an engine overspeed condi-
tion. The transmission will always allow a upshift from
first to second gear, however 2nd - 3rd, 3rd - 4th, and 4th
– 5th upshifts will not be allowed if the vehicle speed is
too low to maintain operation in the selected gear. The
transmission will automatically downshift as the vehicle
slows to a stop (to prevent engine lugging) and will
display the current gear. After a stop, the driver should
manually upshift (D+) the transmission as the vehicle is
accelerated.
246 STARTING AND OPERATING

When in the AutoStickmode, as the engine RPM nears
the engine maximum speed, an “UPSHIFT” message will
appear in the Electronic Vehicle Information Center
(EVIC) portion of your instrument cluster. This message
appears in order to alert the driver that the engine speed
is approaching it’s maximum value and a upshift to the
next gear is required. In the event that the driver does not
upshift, the engine control system will automatically do it
for the driver. Refer to “Electronic Vehicle Information
Center (EVIC)” in “Understanding Your Instrument
Panel” for further information.
Shifting into or out of the AutoStick mode can be done
at any time without taking your foot off the accelerator
pedal. When the driver wishes to engage AutoStick ,
simply move the shift lever to the left or right (D-/D+)
position while in DRIVE. Hold the shift lever to the right for at least one second to
disengage AutoStick. The transmission will now oper-
ate automatically; shifting between the five available
gears.
General Information
•
You can start out in first or second gear. The system
will ignore attempts to upshift at too low of a vehicle
speed.
•The transmission will automatically downshift to first
gear when coming to a stop. Tapping the shift lever to
the D+ position (at a stop) will allow starting in second
gear. After starting, the driver should continue to
manually upshift (D+) as the vehicle is accelerated.
•Starting out in second gear is helpful in snowy or icy
conditions.
•Avoid using speed control when AutoStick
is en-
gaged.

Off” mode by pressing the “ESP OFF” switch. Once the
situation requiring ESP to be switched to the “ESP Partial
Off” mode is overcome, turn ESP back on by momen-
tarily pressing the “ESP OFF” switch. This may be done
while the vehicle is in motion.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an exces-
sively swaying trailer and will take the appropriate
actions to attempt to stop the sway. The system may
reduce engine power and apply the brake of the appro-
priate wheel(s) to counteract the sway of the trailer. TSC
will become active automatically once an excessively
swaying trailer is recognized. No driver action is re-
quired. Note that TSC cannot stop all trailers from
swaying. Always use caution when towing a trailer and
follow the tongue weight recommendations. Refer to
“Trailer Towing” in “Starting and Operating” for further
information. When TSC is functioning, the “ESP/TCS
Indicator Light” will flash, the engine power may bereduced and you may feel the brakes being applied to
individual wheels to attempt to stop the trailer from
swaying. TSC is disabled when the ESP system is in the
“Partial Off” mode.
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and adjust the
trailer load to eliminate trailer sway.
ESP/BAS Warning Light and ESP/TCS Indicator
Light
The malfunction indicator lamp for the ESP is
combined with the BAS indicator. The “ESP/
BAS Warning Light” and the “ESP/TCS Indi-
cator Light” in the instrument cluster both
come on when the ignition switch is turned to the ON
position. They should both go out with the engine
running.

E85 Usage In Non-Flex Fuel Vehicles
Non-FFV vehicles are compatible with gasoline contain-
ing 10% ethanol (E10). Gasoline with higher ethanol
content may void the vehicle’s warranty.
If a Non-FFV vehicle is inadvertently fueled with E85
fuel, the engine will have some or all of these symptoms:
•operate in a lean mode
•OBD II “Malfunction Indicator Light” on
•poor engine performance
•poor cold start and cold driveability
•increased risk for fuel system component corrosion
To fix a Non-FFV vehicle inadvertently fueled once with
E85 perform the following:
•drain the fuel tank (see your authorized dealer)
•change the engine oil and oil filter
•disconnect and reconnect the battery to reset the
engine controller memory
More extensive repairs will be required for prolonged
exposure to E85 fuel.
MMT In Gasoline
MMT is a manganese-containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emissions system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
of gasoline may not be indicated on the gasoline pump,
therefore, you should ask your gasoline retailer whether
the gasoline contains MMT. It is even more important to
look for gasoline without MMT in Canada, because MMT
