Temperature Control
The rotary knob in the center controls
air temperature. Rotate the control to
the left for cooler air temperature and
to the right for warmer air tempera-
ture. Rotating the control to the ex-
treme left provides the coldest setting.
Rotating the control to the extreme
right provides the warmest setting.
Mode Control
The rotary knob on the right controls
airflow distribution. Dots between
each of the mode selections identify
intermediate modes that allow the op-
erator to fine-tune airflow distribu-
tion. The mode settings are as follows:
•Defrost
Air is directed to the windshield through the
outlets at the base of the windshield. Air is
also directed to the front door windows through the
side window demister grilles.NOTE:
To improve fuel economy, leave in defrost only
when necessary.
•Defrost/Floor
Air flows through the front and rear floor
outlets and the outlets at the base of the
windshield. Air is also directed to the front
door windows through the side window demister
grilles.
•
Floor
Air flows through the floor outlets located
under the instrument panel and into the rear
seating area through vents under the front seats.
•
Bi-Level
Air flows through the outlets located in the
instrument panel and through the outlets lo-
cated on the floor. Air flows through the registers in
the back of the center console to the rear seat
passengers. These registers can be closed to par-
tially block airflow.

Automatic Transmission
The gear selector must be in the NEUTRAL or PARK
position before you can start the engine. Apply the brakes
before shifting into any driving gear.
Normal Starting
Normal Starting of either a cold or a warm engine is
obtained without pumping or depressing the accelerator
pedal. Turn the key to the “START” position and release
when the engine starts. If the engine has not started
within 3 seconds, slightly depress the accelerator pedal
while continuing to crank. If the engine fails to start
within 15 seconds, turn the key to the “LOCK” position,
wait 10 to 15 seconds, then repeat the normal starting
procedure.
Extremely Cold Weather (below
20°F or
29°C)
To insure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your dealer) is recommended.
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.
STARTING AND OPERATING 209

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.
•Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with an automatic
transmission cannot be started this way. Un-
burned fuel could enter the catalytic converter and
once the engine has started, ignite and damage the
converter and vehicle. If the vehicle has a dis-
charged 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 proce-
dures and follow them carefully.
If the engine is flooded, it may start to run, but not have
enough power to continue running when the key is
released. If this occurs, continue cranking up to 15
seconds with the accelerator pedal pushed all the way to
the floor. Release the accelerator pedal and the key once
the engine is running smoothly. Do not overspeed the
engine.
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 controlled automatically and it will
decrease as the engine warms up.
210 STARTING AND OPERATING

R (Reverse)
For moving the vehicle rearward. Always stop before
moving the lever to R (Reverse), except when rocking
the vehicle.
N (Neutral)
Engine may be started in this range.
CAUTION!
Coasting the vehicle, or driving for any other reason
with selector lever in NEUTRAL can result in trans-
mission damage.
WARNING!
Do not coast in N (Neutral) and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle and have an accident.
D (Overdrive)
This range should be used for most city and highway
driving. It provides the smoothest up shifts and down
shifts, and the best fuel economy. Select the “3” range
when frequent transmission shifting occurs when us-
ing the Overdrive range, such as when operating the
vehicle under heavy loading conditions (in hilly ter-
rain, traveling into strong head winds, or while tow-
ing heavy trailers.
NOTE:
•
If the vehicle is started in cold temperatures, shifts into
Overdrive may be delayed. Normal Overdrive and
shifting operation will resume when the temperature
of the transmission reaches the appropriate tempera-
ture. Refer to the “Note” under “Torque Converter
Clutch” later in this section.
•If the transmission temperature gets too hot, the
transmission may downshift out of Overdrive or en-
gage overdrive at higher vehicle speeds until the
transmission cools down. After cooldown, Overdrive
will resume normal operation.
216 STARTING AND OPERATING

3 (Third)
This range eliminates shifts into Overdrive. The trans-
mission will operate normally in First, Second and
Third while in this range. The “3” position should also
be used when descending steep grades to prevent
brake system distress.
NOTE:
Using the “3” range while operating the vehicle
under heavy operating conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat build up.
L (Low)
This range should be used for engine braking when
descending very steep grades. In this range, upshifts
will occur only to prevent engine overspeed while
downshifts occur earlier than other gear range selec-
tions.
CAUTION!
Never race the engine with the brakes on and the
vehicle in gear, and never hold the vehicle on an
incline without applying the brakes. These practices
can cause overheating and damage to the transmis-
sion.
Torque Converter Clutch
A feature designed to improve fuel economy has been
added to the automatic transmission of this vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly differ-
ent feeling or response during normal operation in high
gear. When the vehicle speed drops, or during accelera-
tion, the clutch automatically and smoothly disengages.
NOTE:
•
The torque converter clutch will not engage until the
transmission fluid and engine coolant is warm (usu-
ally after 1–3 miles (1.6–4.8 km) of driving). Because
engine speed is higher when the torque converter

D (Drive)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts and best fuel economy.
The transmission automatically upshifts through fifth
gear. The D (Drive) position provides optimum driving
characteristics under all normal operating conditions.
When frequent transmission shifting occurs when using
the Overdrive range, such as when operating the vehicle
under heavy loading conditions (in hilly terrain, travel-
ing into strong head winds, or while towing heavy
trailers, use the AutoStickmode and select the “3”
range.
AutoStickGear selection
The AutoStickfeature can be selected by pressing the
selector lever to the right or the left with the lever in the
D (Drive) position. The gear currently selected is indi-
cated in the instrument cluster display. Briefly, press the
selector lever in the “D -” direction and the transmission
will shift from the current gear to the next lower gear.Press and hold the selector lever in the “D-” direction and
the transmission will shift from the current gear directly
to the next lowest gear for best acceleration.
NOTE:To avoid overrevving the engine when the
selector lever is moved in “D -” direction, the transmis-
sion will not shift to a lower gear if the engine’s revolu-
tions per minute (RPM) limit would be exceeded.
Briefly, press the selector lever in the “D +” direction and
the transmission will shift from the current gear to the
next higher gear.
Press and hold the selector lever in the “D +” direction
and the transmission will shift from the current gear
directly to gear “D.”
WARNING!
On slippery road surfaces, never downshift in order to
obtain braking action. This could result in drive wheel
slip and reduced vehicle control. Your vehicle’s ABS
will not prevent this type of loss of control. You could
lose control of your vehicle and have an accident.

MULTI DISPLACEMENT SYSTEM (MDS) - 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.
TRACTION CONTROL SYSTEM (TCS) — IF
EQUIPPED
WARNING!
The Traction Control System (TCS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded. The
TCS cannot prevent accidents, including those re-
sulting from excessive speed in turns, or hydroplan-
ing. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of a TCS-
equipped vehicle must never be exploited in a reck-
less or dangerous manner, which could jeopardize
the user’s safety or the safety of others.
The Traction Control System (TCS) Indicator
Light, located in the instrument cluster, starts
to flash as soon as the tires lose traction and the
wheels begin to spin. This indicates that the
TCS is active. If the indicator light begins to flash during
