If Engine Fails to Start
WARNING!
•Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.
(Continued)
WARNING! (Continued)
•Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with an automatic
transmission 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 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 dan-
gerous if done improperly. Refer to Section 6 of
this manual for proper jump starting procedures
and follow them carefully.
260 STARTING AND OPERATING

After Starting
The idle speed will automatically decrease as the engine
warms up.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat buildup may
cause serious injury or death.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a
grounded three-wire extension cord.
•The engine block heater cord is found under the hood
clipped to the heater line on the left side of the engine.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 Volt AC electrical cord could
cause electrocution.
Use the heater when temperatures below 0 °F (-18 °C) are
expected to last for several days.
AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.

262 STARTING AND OPERATING

4–Speed Automatic Transmission (3.7L Engine)
NOTE:Under extreme cold temperatures (-6°F (-21°C)
and when in DRIVE, transmission operation may be
briefly limited to only 2nd gear operation. Normal op-
eration will resume once the transmission temperature
has risen to a suitable level.
Shifting from DRIVE to PARK or REVERSE should be
done only after the accelerator pedal is released and the
vehicle is stopped. Be sure to keep your foot on the brake
when moving the shift lever between these gears.
Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL position into another gear range.
Shift Lever
STARTING AND OPERATING 265
5

NEUTRAL
Move the shift lever into this gear only after the vehicle
has come to a complete stop. Always depress and main-
tain firm pressure on the brake pedal while in this range.
Apply the parking brake when leaving the vehicle in this
range for extended periods of time. The engine may be
started in this range.
NOTE:Towing the vehicle, coasting, or driving for any
other reason with shift lever in NEUTRAL can result in
severe transmission damage. Refer to “Recreational Tow-
ing” in Section 5 and “Towing a Disabled Vehicle” in
Section 6 of this manual.
DRIVE
For most city and highway driving.
2 (Second)
For moderate grades and to assist braking on dry pavement
or in mud and snow. Begins at a stop in low gear with
automatic upshift to 2nd gear. Will not shift to 3rd gear.
1 (First)
For hard pulling at low speeds in mud, sand, snow, or on
steep grades. Begins and stays in low gear with no upshift.
Provides engine compression braking at low speeds.
Overdrive Operation
The overdrive automatic transmission contains an elec-
tronically controlled 4th speed (OVERDRIVE). The trans-
mission will automatically shift from 3rd gear to OVER-
DRIVE if the following conditions are present:
•the shift lever is in DRIVE
•the engine coolant has reached normal operating tem-
perature
•vehicle speed is above approximately 30 mph
(48 km/h)
•the TOW/HAUL button has not been activated
•the transmission has reached normal operating
temperature
STARTING AND OPERATING 267
5

NOTE:If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into OVER-
DRIVE and will automatically select the most desirable
gear for operation at this temperature. Normal operation
will resume when the transmission fluid temperature has
risen to a suitable level. Refer also to the note under
torque converter clutch, later in this section.
If the transmission temperature gets extremely hot, the
transmission will automatically select the most desirable
gear for operation at this temperature. If the transmission
temperature becomes hot enough, the “Transmission
Temperature Warning Light” may illuminate and the
transmission may downshift out of OVERDRIVE until
the transmission cools down. After the transmission cools
down, the transmission will resume normal operation.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 TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the TOW/HAUL button. This will improve
performance and reduce the potential for transmission
overheating or failure due to excessive shifting. When
operating in TOW/HAUL mode, the transmission will
shift to 3rd gear.
268 STARTING AND OPERATING

If the problem is no longer detected, the transmission will
return to normal operation. If the problem persists,
PARK, REVERSE, and NEUTRAL will continue to oper-
ate. Only 2nd gear range will operate in the DRIVE
position. Have the transmission checked at your autho-
rized dealer as soon as possible.
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.
5–Speed Automatic Transmission (4.0L Engine)
The electronically controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating; therefore, the first few shifts on a newvehicle may be somewhat abrupt. This is a normal
condition and precision shifts will develop within a few
hundred miles/kilometers.
Shift Lever
270 STARTING AND OPERATING

NEUTRAL
Shift into NEUTRAL when the vehicle is standing for
prolonged periods with the engine running. The engine
may be started in this range. Set the parking brake if you
must leave the vehicle.
NOTE:Towing the vehicle, coasting, or driving for any
other reason with the shift lever in NEUTRAL can result
in severe transmission damage. Refer to “Recreational
Towing” in Section 5 and “Towing a Disabled Vehicle” in
Section 6 of this manual.
DRIVE
The transmission automatically upshifts through 5th
gear. The DRIVE position provides optimum driving
characteristics under all normal operating conditions.
Electronic Range Select (ERS)Operation
The Electronic Range Select (ERS) shift control allows
you to move the shift lever left (-) or right (+) when the
shift lever is in the DRIVE position, allowing the selectionof the desired top gear. For example, if the driver shifts
the transmission into 3rd gear, the transmission will
never shift above 3rd gear, but can shift down to 2nd gear
or 1st gear, when needed.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid.

NOTE:To select the proper gear position for maximum
deceleration (engine braking), move the shift lever to the
left “D (-)” and hold it there. The transmission will shift
to the range from which the vehicle can best be slowed
down.
