²When ªrockingº a stuck vehicle by shifting between a
forward gear and reverse, do not spin wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result.

CAUTION!
Failure to follow the recommended downshifting
speeds may cause the engine to over speed and/or
damage the clutch disc even if the clutch pedal is
depressed.
AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
²Shift into P (Park) only after the vehicle has come
to a complete stop.
²Shift into or out of R (Reverse) only after the
vehicle has come to a complete stop and the engine
is at idle speed.
²Do not shift from R (Reverse), P (Park), or N
(Neutral) into any forward gear when the engine is
above idle speed.
²Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
252 STARTING AND OPERATING

WARNING!
It is dangerous to shift the selector lever out of P
(Park) or N (Neutral) if the engine speed is higher
than idle speed. If your foot is not firmly on the
brake pedal, the vehicle could accelerate quickly
forward or in reverse. You could lose control of the
vehicle and hit someone or something. Only shift
into gear when the engine is idling normally and
when your foot is firmly on the brake pedal.
Shift Lock Manual Override Ð If Equipped
Your vehicle may be equipped with a shift lock manual
override. The manual override may be used in the event
that the shift lever should fail to move from Park with the
key in the ON position and the brake pedal depressed. To
operate the shift lock manual override, perform the
following steps:
1. Firmly set the parking brake.
2. Using a flat blade screwdriver, carefully remove the
shift lock manual override cover which is located on the
PRNDL bezel.
3. Depress and maintain firm pressure on the brake
pedal.

4. Using the screwdriver, reach into the manual override
opening. Press and hold the shift lock lever down.5. Move the shift lever into the N (Neutral) position.
6. The vehicle may then be started in N (Neutral).
Have your vehicle inspected by your local authorized
dealer, if the shift lock manual override has been used.
Brake/Transmission Interlock System
This system prevents you from moving the gear shift out
of P (Park) and into any gear unless the brake pedal is
pressed. Always depress thebrake pedal first,before
moving the gear selector out of P (Park).
254 STARTING AND OPERATING

4±Speed Automatic Transmission (3.7L Engine)
Shifting from D (Drive) to P (Park) or R (Reverse) (or
from P or R to D) 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 P (Park) or
N (Neutral) position into another gear range.
P (Park)
This gear position supplements the parking brake by
locking the transmission. The engine can be started in
this range. Never use P (Park) while the vehicle is in
motion. Apply the parking brake when leaving the
vehicle in this range. Always apply parking brake first,
then place the selector in P (Park) position.
WARNING!
Never use P (Park) position as a substitute for the
parking brake. Always apply parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.

WARNING!
It is dangerous to shift the selector lever out of P
(Park) or N (Neutral) if the engine speed is higher
than idle speed. If your foot is not firmly on the
brake pedal, the vehicle could accelerate quickly
forward or in reverse. You could lose control of the
vehicle and hit someone or something. Only shift
into gear when the engine is idling normally and
when your right foot is firmly on the brake pedal.
R (Reverse)
Use this range only after the vehicle has come to a
complete stop.N (Neutral)
Shift into N (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 selector lever in N (Neutral) can result
in severe transmission damage. Refer to ªRecreational
Towingº in Section 5 and ªTowing a Disabled Vehicleº in
Section 6 of this manual.
D (Drive)
For most city and highway driving.
2 (Second)
For moderate grades and to assist braking on dry pave-
ment or in mud and snow. Begins at a stop in low gear
with automatic upshift to 2nd gear. Will not shift to 3rd.
256 STARTING AND OPERATING

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 fourth and fifth speed (Overdrive).
The transmission will automatically shift from 3rd gear to
Overdrive if the following conditions are present:
²the transmission selector is in D (Drive);
²the engine coolant has reached normal operating tem-
perature;
²vehicle speed is above approximately 30 mph (48
km/h);
²the ªTOW/HAULº button has not been activated;
²transmission has reached normal operating tempera-
ture.
NOTE:If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into Overdrive
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 ªTransmission
Temperature Warning Lightº may illuminate and the
transmission may downshift out of Overdrive until the
transmission cools down. After cooldown, the transmis-
sion will resume normal operation.
STARTING AND OPERATING 257

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 improve
performance and reduce the potential for transmission
overheating or failure due to excessive shifting. When
operating in ªTOW/HAULº mode, the transmission will
shift to 3rd gear and 4th will be enabled under steady
cruise conditions.
The ªTOW/HAUL Indicator Lightº will illuminate in the
instrument 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 switch must be pressed each time the engine is
started.

258 STARTING AND OPERATING

Transmission Limp Home Mode
Transmission function is monitored for abnormal condi-
tions. If a condition is detected that could result in
transmission damage, the transmission limp home mode
will be engaged. In this mode, the transmission will
remain in the current gear until the vehicle is brought to
a stop.
To reset the transmission, use the following procedure:
1. Stop the vehicle.
2. Move the shift lever to the P (Park) position.
3. Turn off the engine, be sure to turn the key to the
LOCK position.
4. Wait approximately 10 seconds, then restart the en-
gine.
5. Move the shift lever to the desired gear range.If the problem is no longer detected, the transmission will
return to normal operation. If the problem persists, P
(Park), R (Reverse), and N (Neutral) will continue to
operate. Only Second gear range will operate in the D
(Drive) shifter position. Have the transmission checked at
your authorized 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 new
vehicle, may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
hundred miles.
Gear Ranges
NOTE:After selecting any gear range, wait a moment to
allow the selected gear to engage before accelerating.
This is especially important when the engine is cold. If
there is a need to restart the engine be sure to cycle the
key to the LOCK position before restarting. Transmission
