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.
•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 isapplied. 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.
To rock a vehicle out of soft ground (mud or snow),
alternately shift from forward to reverse, while applying
only slight acceleration. Rocking a vehicle free in this
manner may cause the ABS or traction system malfunc-
tion indicator light to come on. Turn off the engine and
restart the engine to clear the malfunction indication.

An UPSHIFT message will appear in the Electronic
Vehicle Information Center (EVIC) portion of your instru-
ment cluster when using Autostick. This message ap-
pears in order to alert the driver to upshift to the next
gear. The UPSHIFT message will display while operating
the vehicle at higher engine revolutions–per–minute
(RPM).
Shifting into or out of the autostick mode can be done at
any time without taking your foot off the accelerator
pedal. When the driver wishes to engage autostick,
simply move the shift lever to the Left or Right (D-/D+)
position while in DRIVE.
Hold the shift lever to the right for at least one second to
disengage autostick. The transmission will now operate
automatically; shifting between the five available gears.Autostick General Information
•
You can start out in first or second gear. The system
will ignore attempts to upshift at too low of a vehicle
speed.
•The transmission will automatically downshift to first
gear when coming to a stop.
•Starting out in second gear is helpful in snowy or icy
conditions.
•Avoid using speed control when autostick is engaged.
•The transmission will not automatically shift up when
maximum engine speed is reached while autostick is
engaged.
•Transmission shifting will be more noticeable when
autostick is engaged.

•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
Tires–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.

The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
Refer to the following illustrations.
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.

Page 246 of 344

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.
Extended driving at high RPM should be avoided to
prevent excess heat generation. A reduction in vehicle
speed may be required to avoid extended driving at
high RPM. Return to a higher gear range or vehicle
speed when road conditions and RPM level allows.
