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 (below20°F or29°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.

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.
236 STARTING AND OPERATING

The following indicators should be used to ensure that
you have engaged the selector lever into the P (Park)
position:
•When shifting into P (Park) move the lever all the way
forward until it stops, and is fully seated.
•Look at the shift indicator display on the instrument
panel to ensure it is in the P (Park) position.
CAUTION!
Damage to the shifter could result if the selector
lever is moved out of P (Park) before the ignition is
turned from the LOCK to ON position.
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.
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 selections.
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 transmission.
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

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 (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!
Continued operation with reduced power steering
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
CAUTION!
Prolonged operation of the steering system at the
end of the steering wheel travel will increase the
steering fluid temperature and it should be avoided
when possible. Damage to the power steering pump
may occur.
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.

2. Economy—
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 Stability—
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 “B”
pillar.
Some vehicles may have Supplemental Tire Pressure
Information for vehicle loads that are less than the
maximum loaded vehicle condition. These pressure con-
ditions will be found in the “Supplemental Tire Pressure
Information” 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
check tire pressure. Do not make a visual judgement
when determining proper inflation. Radial tires may look
properly inflated even when they are under inflated.Tire Placard Location

CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when
using replacement equipment that is not of the
same size, type, and/or style. After-market wheels
can cause sensor damage. Do not use tire sealant
from a can, or balance beads if your vehicle is
equipped with a TPMS, as damage to the sensors
may result.
•After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure
Monitoring Sensor.
NOTE:
•
The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
•The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
•Driving 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.
•The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the Tire
Pressure Monitoring Telltale light.

FUEL REQUIREMENTS
2.7L Engine
Your vehicle is designed to meet all emis-
sions regulations and provide satisfactory
fuel economy and performance when us-
ing high quality unleaded gasoline having
an octane of 87.
3.5L and 5.7L Engines
The 3.5L and 5.7L engines are designed to
meet all emissions regulations and provide
satisfactory fuel economy and perfor-
mance when using high-quality unleaded
gasoline with an octane rating of 87 to 89.
The manufacturer recommends the use of
89-octane for optimum performance. The routine use of
premium gasoline is not recommended. The use of
premium gasoline will provide no benefit over high
quality regular gasoline or mid-grade gasoline and in
some circumstances may result in poorer performance.Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required.
Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of “regular” gasoline be-
fore considering service for the vehicle.
Over 40 automobile manufacturers around the world
have issued and endorsed consistent gasoline specifica-
tions (the World Wide Fuel Charter, WWFC) which
define fuel properties necessary to deliver enhanced
emissions, engine performance, and durability for your
vehicle. The manufacturer recommends the use of gaso-
lines that meet the WWFC specifications if they are
available.
