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
clutch is not engaged, it may seem as if the transmis-
sion is not shifting into“Overdrive”when cold. This is
considered a normal condition. Pulling the shift lever
into the“3”position will show that the transmission is
able to shift into and out of“Overdrive.”
•If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
transmission fluid partially draining from the torqueconverter into the transmission. This is considered a
normal condition and will not cause damage to the
transmission. The torque converter will refill within 5
seconds of shifting from P (Park) into any other gear
position.
Transmission Limp Home Mode
The transmission is monitored for abnormal conditions.
If a condition is detected that could cause damage, the
transmission automatically shifts into second gear. The
transmission remains in second gear despite the forward
gear selected. Park (P), Reverse (R), and Neutral (N) will
continue to operate. This Reset feature allows the vehicle
to be driven to a dealer for service without damaging the
transmission.
If the problem has been momentary, the transmission can
be reset to regain all forward gears.
•Stop the vehicle and shift into PARK (P).
•Turn the key to LOCK then start the engine.
•Shift into“D”and resume driving.

NOTE:Even if the transmission can be reset, we
recommend that you visit a dealer at your earliest
possible convenience. Your dealer has diagnostic equip-
ment to determine if the problem could recur.
If the transmission cannot be reset, dealer service is
required.
5 Speed Automatic Transmission
WARNING!
Unintended movement of a vehicle could injure
those in and near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle you should shift
the transmission into Park, remove the key from the
ignition, and apply the park brake. Once the key is
removed from the ignition the transmission shift
lever is locked in the Park position, securing the
vehicle against unwanted movement. Furthermore,
you should never leave children unattended inside a
vehicle. The following indicators should be used to
ensure that you have engaged the transmission shift
lever into the“Park”position:
•When shifting into Park move the lever all the
way forward until it stops, and is fully seated.
•Look at the shift indicator window on the console
to ensure it is in the“P”position.

Neutral
No power is transmitted from the engine to the drive
axle. When the brakes are released, the vehicle can be
moved freely (pushed or towed). Do not engage in
NEUTRAL position while driving except to coast when
the vehicle is in danger of skidding (e.g., on icy roads).
The engine may be started in this range. Use this range
for starting your vehicle if it is moving or being towed.
CAUTION!
Coasting the vehicle, or driving for any other reason
with selector lever in NEUTRAL can result in trans-
mission damage.
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 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 AutoStick mode and select the“3”range.
AutoStickGear selection
The transmission gear can be selected by pressing the
selector lever to the right or the left with the selector lever
in the DRIVE position. The gear currently selected is
indicated in the instrument cluster display. Briefly press
selector lever in the“D-”direction. The transmission will
shift from the current gear to the next lower gear. Shifting
into another gear that allows for quicker acceleration or
to slow the vehicle down is possible. Downshifts can also
be performed.
Press and hold the selector lever in the“D-”direction.
The transmission will shift from the current gear directly
to the best gear for acceleration.

Automatic Transmission—General Information
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.
•Shift into or out of REVERSE only after the
vehicle has come to a complete stop and the
engine is at idle speed.
•Do not shift from REVERSE, PARK or NEUTRAL
into any forward gear when the engine is above
idle speed.
•Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
The automatic transmission selects individual gears au-
tomatically, dependent upon:
•Altitude
•Vehicle Loading
•Driving Style
•Selector lever position
•Accelerator position
•Vehicle speed
The gear shifting process is continuously adapted, de-
pendent on the driving style, the driving situation and
the road characteristics.
NOTE:
•
After selecting any driving position, wait a moment to
allow the gear to fully engage before accelerating,
especially when the engine is cold.
220 STARTING AND OPERATING
ProCarManuals.com

•If there is a need to restart your engine be sure to cycle
the key to the LOCK position before restarting. Trans-
mission engagement may be delayed up to 10 seconds
after restart if the key is not cycled to the LOCK
position first.
•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 or soft until after the
break-in period. This is a normal condition, and pre-
cision shifts will develop within a few shift cycles.
WARNING!
It is dangerous to shift the selector lever out of PARK
or 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.
The selector lever is automatically locked while in the
PARK position. To move the selector lever out of the
PARK position, the brake pedal must be firmly depressed
before the shift lock will release.
Shift the selector lever to the desired position only when
the engine is idling normally and the brake pedal is
applied. Do not release the brake until ready to drive. The
vehicle may otherwise accelerate quickly when the selec-
tor lever is in DRIVE or REVERSE position.
Stopping
For brief stops, leave the transmission in gear and hold
the vehicle with the brake pedal. For longer stops with
the engine idling, shift into the NEUTRAL or PARK
position and hold the vehicle with the parking brake.
When stopping the vehicle uphill, do not hold it with the
accelerator; use the brake. This avoids unnecessary trans-
mission heat build-up.
Maneuvering
To maneuver in tight areas, control the vehicle speed by
gradually releasing the brakes. Accelerate gently and
never abruptly step on the accelerator.

You can shift in or out of the autostick mode at any time
without taking your foot off the accelerator pedal. If you
choose the Overdrive mode, the transmission will oper-
ate automatically; shifting between the five available
gears. When you wish to engage autostick, simply move
the shift lever to the Right or Left (D+/D-) position while
in DRIVE. The transmission will remain in the current
gear until an upshift or downshift is chosen.
PARKING BRAKE
When the parking brake is applied with the ignition
switch on, the brake light in the instrument cluster will
turn on.
NOTE:This light only shows that the parking brake is
applied. It does not show the degree of brake application.Before leaving the vehicle, make sure that the parking
brake is fully applied and place the gear selector in the
Park position.

•Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle automatic transmission in
P for Park. Always, block orchockthe trailer wheels.
•GCWR must not be exceeded.
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch utilized
(This requirement may limit the ability to always
achieve the 10% to 15% range of tongue weight as a
percentage of total trailer weight).
Towing Requirements—Tires

Do not attempt to tow a trailer while using a compact
spare tire.
Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to the
Ti re s–General Information section of this manual on
Tire Pressures for proper tire inflation procedures.
Also, check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to the Tires–General
Information section of this manual on Tread Wear
Indicators for the proper inspection procedure.
When replacing tires refer to the Tires–General Infor-
mation section of this manual on Replacement Tires for
proper tire replacement procedures. Replacing tires
with a higher load carrying capacity will not increase
the vehicle’s GVWR and GAWR limits.
Towing Requirements—Trailer Brakes

Donotinterconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.
Towing Tips—Automatic Transmission
The“D”range can be selected when towing. However, if
frequent shifting occurs while in this range, the“3”range
should be selected.
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. This action will also
provide better engine braking.
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. See Schedule“B”in
section 8 of this manual for transmission fluid change
intervals.
NOTE:Check the automatic transmission fluid level
before towing.
Towing Tips—Electronic Speed Control (If
Equipped)

Don’t use in hilly terrain or with heavy loads.
When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Towing Tips—Autostick (If Equipped)

For vehicles equipped with Autostick. By using the
Autostick modes, and selecting a specific gear range,
frequent shifting can be avoided. The highest gear
range should be selected that allows for adequate
performance. For example, choose“4”if the desired
speed can be maintained. Choose“3”or“2”if needed
to maintain the desired speed.

WARNING!
•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 another vehicle. This type of
start can be dangerous if done improperly, so
follow this procedure carefully.
•Battery fluid is a corrosive acid solution; do not
allow battery fluid to contact eyes, skin or clothing.
Don’t lean over battery when attaching clamps or
allow the clamps to touch each other. If acid
splashes in eyes or on skin, flush contaminated area
immediately with large quantities of water.
•A battery generates hydrogen gas which is flam-
mable and explosive. Keep flame or spark away
from the vent holes. Do not use a booster battery
or any other booster source with an output that
exceeds 12 volts.
NOTE:The battery is stored under an access cover in
the trunk. Remote battery terminals are located in the
engine compartment for jump starting.
NOTE:The battery in this vehicle has a vent hose that
should not be disconnected and should only be replaced
with a battery of the same type (vented).
1. Wear eye protection and remove any metal jewelry
such as watch bands or bracelets that might make an
inadvertent electrical contact.
2. When boost is provided by a battery in another
vehicle, park that vehicle within booster cable reach and
without letting the vehicles touch. Set the parking brake,
place the automatic transmission in PARK and turn the
ignition switch to the OFF (or LOCK) position for both
vehicles.
3. Turn off the heater, radio and all unnecessary electrical
loads.
