engine speed or power may be noticed when the com-
pressor cycles. This is a normal occurrence since the
compressor will cycle on and off to maintain comfort and
improve fuel economy.
Recirculate Button
Press this button to recirculate the air inside the
vehicle. Outside air is prevented from entering
the vehicle. Use this mode to temporarily block
out any outside odors, smoke, dust or when
rapid cooling of the interior is required.
Manual control of Recirculation is possible only in Panel,
Floor, and Bi-Level modes. It will not operate in Mix, or
Defrost modes. The recirculation symbol will flash three
times indicating recirculation is not available in these
modes.NOTE:If the interior of the windows begin to fog, press
the recirculate button to return to outside air. Some
conditions will cause captured interior air to fog win-
dows when in recirculate mode.
Panel
Air flows through the outlets located in the instru-
ment panel. These outlets can be adjusted to direct
the airflow.
Floor (Heat)
Air flows primarily through the floor outlets lo-
cated under the instrument panel. A small amount
of air is directed through the defrost and side window
demister outlets.
Mix
Outside air flows in equal proportions through the
floor and defroster outlets.

Tip Start Feature
Your vehicle has a ªTip Startº starting system. With ªTip
Startº the driver does not need to hold the key in the
'Start' position until the vehicle starts, but can release the
key (still in the ignition) and the vehicle will continue
through the start cycle.
²Turn the ignition key to the START position, until the
start motor engages.
²Release the key (still in the ignition) and the starter
will continue through the start cycle until the vehicle
starts or for 5 seconds (whichever comes first).
If Engine Fails To Start
If the engine fails to start after you have followed the
Normal Starting procedure, it may be flooded. Push the
accelerator pedal all the way to the floor and hold it there
while cranking the engine. This should clear any excess
fuel in case the engine is flooded.
CAUTION!
To prevent damage to the starter, do not crank the
engine for more than 15 seconds at a time. Wait 10 to
15 seconds before trying again.
WARNING!
Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
274 STARTING AND OPERATING

WARNING!
Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle. If the vehicle has a discharged battery,
booster cables may be used to obtain a start from a
booster battery or the battery in another vehicle. This
type of start can be dangerous if done improperly.
See section 6 of this manual for the proper jump
starting procedures and follow them carefully.If the engine has been flooded, it may start to run, but not
have enough power to continue running when the key is
released. If this occurs, continue cranking with the accel-
erator pedal pushed all the way to the floor. Release the
accelerator pedal and the key once the engine is running
smoothly.
If the engine shows no sign of starting after two 15
second periods of cranking with the accelerator pedal
held to the floor, the Normal Starting procedure should
be repeated.
After Starting
The idle speed is automatically controlled on fuel injected
engines and will decrease as the engine warms up.

The transmission will downshift from Overdrive to Drive
if the accelerator pedal is fully depressed at vehicle
speeds above approximately 35 mph (56 km/h).
When To Use ªTOW/HAULº Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the ªTOW/HAULº button. This will improveperformance and reduce the potential for transmission
overheating or failure due to excessive shifting. When
operating in ªTOW/HAULº mode, 5th gear (if
equipped) is disabled and 2-3 and 3-4 shift patterns are
modified. Shifts into Overdrive (4th gear) are allowed
during steady cruise (for improved fuel economy) and
automatic closed-throttle downshifts to 3rd gear (for
improved braking) will occur during steady braking.
The ªTOW/HAULº light will illuminate in the instru-
ment cluster to indicate when the switch has been
activated. Pressing the switch a second time restores
normal operation. If the ªTOW/HAULº mode is desired,
the button must be pressed each time the engine is
started.
Torque Converter Clutch
A feature designed to improve fuel economy is included
in all automatic transmissions. A clutch within the torque
converter engages automatically at a calibrated speed at
280 STARTING AND OPERATING

TSC (Trailer Sway Control)
TSC uses sensors in the vehicle to recognize a swaying
trailer and will take the appropriate actions to attempt to
stop the sway. The system will reduce engine power and
apply individual brakes that will counter act the sway of
the trailer. TSC will become active automatically once the
swaying trailer is recognized. No driver action is re-
quired. TSC can not stop all trailers from swaying.
Always use caution when towing a trailer and follow the
tongue weight recommendations. Refer to9Trailer Tow-
ing9in section 5 of this manual for other information on
towing a trailer with your vehicle.
MULTI DISPLACEMENT SYSTEM (MDS) Ð 5.7L
Engine Only
This feature offers improved fuel economy by shutting
off four of the engine's eight cylinders during light load
and cruise conditions. The system is automatic with no
driver inputs or additional driving skills required.
NOTE:The MDS system may take some time to return
to full functionality after a battery disconnect.
304 STARTING AND OPERATING

2. EconomyÐ
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Under inflation, also increases
tire rolling resistance and results in higher fuel consump-
tion.
3. Ride Comfort and Vehicle StabilityÐ
Proper tire inflation contributes to a comfortable ride.
Over inflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed either on
the face of the driver's door or on the driver's side ªBº
pillar.
Some vehicles may have Supplemental Tire Pressure
Information for vehicle loads that are less than themaximum loaded vehicle condition. These pressure con-
ditions will be found in the ªSupplemental Tire Pressure
Informationº section of this manual.
The pressure should be checked and adjusted as well as
inspecting for signs of tire wear or visible damage at least
once a month. Use a good quality pocket-type gauge to

314 STARTING AND OPERATING

NOTE:
²The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
²The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
²Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle's handling and
stopping ability.
²The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver 's responsibility to maintain
correct tire pressure using an accurate tire gauge, even
if under-inflation has not reached the level to trigger
illumination of the Tire Pressure Monitoring Telltale
lamp.
²Seasonal temperature changes will affect tire pressure,
and the TPM system will monitor the actual tire
pressure in the tire.
Base System ± If Equipped
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the Receiver Module.
NOTE:It is particularly important, for you to check the
tire pressure in all of your tires regularly and to maintain
the proper pressure.
The Tire Pressure Monitoring System (TPMS) consists of
the following components:
²Receiver Module
²4 Tire Pressure Monitoring Sensors
