Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the transmission gear
selector in PARK unless the brakes are applied. To shift the
transmission out of PARK, the ignition must be turned to
the ON/RUN position (engine running or not) and the
brake pedal must be pressed.
Five-Speed Automatic Transmission — If Equipped
The transmission gear position display (located in the
instrument cluster) indicates the transmission gear range.
You must press the brake pedal to move the gear selector
out of PARK (refer to “Brake/Transmission Shift Interlock
System” in this section). To drive, move the gear selector
from PARK or NEUTRAL to the DRIVE position.
The electronically-controlled transmission adapts its shift
schedule based on driver inputs, along with environmental
and road conditions. 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
(kilometers).Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped. Be
sure to keep your foot on the brake pedal when shifting
between these gears.
The transmission gear selector has only PARK, REVERSE,
NEUTRAL, and DRIVE shift positions. Manual shifts can
be made using the Autostick shift control (refer to
AutoStick
in this section). Moving the gear selector to the
left or right (-/+) while in the DRIVE position will manu-
ally select the transmission gear and will display the
current gear in the instrument cluster as 1, 2, 3, etc.
Gear Selector
6
STARTING AND OPERATING 295

The following indicators should be used to ensure that you
have engaged the transmission into the PARK position (P):
•When shifting into PARK, firmly move the gear selector
all the way forward and to the left until it stops and is
fully seated.
• Look at the transmission gear position display and
verify that it indicates the PARK position (P).
• With brake pedal released, verify that the gear selector
will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.
NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. The engine may be
started in this range. Apply the parking brake and shift the
transmission into PARK if you must leave the vehicle.
WARNING!
Do not coast in 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 a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage. Refer to “Recreational
Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “In Case Of Emergency” for
further information.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission automatically
upshifts through underdrive first, second, and third gears,
direct fourth gear and overdrive fifth gear. The DRIVE
position provides optimum driving characteristics under
all normal operating conditions.
298 STARTING AND OPERATING

When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, traveling into strong head winds, or while
towing a heavy trailer), use the AutoStick shift control
(refer to “AutoStick” in this section for further information)
to select a lower gear. Under these conditions, using a
lower gear will improve performance and extend transmis-
sion life by reducing excessive shifting and heat buildup.
Transmission Limp Home Mode
Transmission function is monitored electronically for ab-
normal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission remains
in the current gear until the vehicle is brought to a stop.
After the vehicle has stopped, the transmission will remain
in second gear regardless of which forward gear is selected.
PARK, REVERSE, and NEUTRAL will continue to operate.
The Malfunction Indicator Light (MIL) may be illuminated.
Limp Home Mode allows the vehicle to be driven to an
authorized dealer for service without damaging the trans-
mission.In the event of a momentary problem, the transmission can
be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition to the LOCK/OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.
NOTE: Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your earliest
possible convenience. Your authorized dealer has diagnos-
tic equipment to determine if the problem could recur. If
the transmission cannot be reset, authorized dealer service
is required.6
STARTING AND OPERATING 299

Overdrive Operation
The automatic transmission includes an electronically con-
trolled Overdrive (fifth gear). The transmission will auto-
matically shift into Overdrive if the following conditions
are present:
•The gear selector is in the DRIVE position.
• Vehicle speed is sufficiently high.
• The driver is not heavily pressing the accelerator.
Autostick
AutoStick is a driver-interactive transmission feature pro-
viding manual shift control, giving you more control of the
vehicle. AutoStick allows you to maximize engine braking,
eliminate undesirable upshifts and downshifts, and im-
prove overall vehicle performance.
This system can also provide you with more control during
passing, city driving, cold slippery conditions, mountain
driving, trailer towing, and many other situations.
Operation
When the gear selector is in the DRIVE position, the
transmission will operate automatically, shifting between
the five available gears. To engage AutoStick, simply tap
the gear selector to the right or left (+/-) while in the DRIVE position. Tapping (-) to enter AutoStick mode will
downshift the transmission to the next lower gear, while
using (+) to enter AutoStick mode will retain the current
gear. When AutoStick is active, the current transmission
gear is displayed in the instrument cluster.
In AutoStick mode, the transmission will shift up or down
when (+/-) is manually selected by the driver, unless an
engine lugging or overspeed condition would result. It will
remain in the selected gear until another upshift or down-
shift is chosen, except as described below.
•
The transmission will automatically upshift when nec-
essary to prevent engine over-speed.
• Heavily pressing the accelerator pedal will generate an
automatic downshift (for improved acceleration) when
reasonable.
• The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear.
• The transmission will automatically downshift to first
gear when coming to a stop. After a stop, the driver
should manually upshift (+) the transmission as the
vehicle is accelerated.
300 STARTING AND OPERATING

•You can start out, from a stop, in first or second gear.
Tapping (+) (at a stop) will allow starting in second gear.
Starting out in second gear can be helpful in snowy or
icy conditions.
• The system will ignore attempts to upshift at too low of
a vehicle speed.
• Avoid using speed control when AutoStick is engaged.
• Transmission shifting will be more noticeable when
AutoStick is enabled.
NOTE: When the transfer case is in the 4L (Low) range, the
transmission will shift automatically (but no higher than
the displayed gear).
To disengage AutoStick mode, hold the gear selector to the
right (+) until Dis once again displayed in the instrument
cluster. You can shift in or out of the AutoStick mode at any
time without taking your foot off the accelerator pedal.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their grip
and the vehicle could skid, causing a collision or
personal injury.
FOUR–WHEEL DRIVE OPERATION (COMMAND-
TRAC I OR ROCK-TRAC)
WARNING!
Failure to engage a transfer case position completely
can cause transfer case damage or loss of power and
vehicle control. You could have a collision. Do not
drive the vehicle unless the transfer case is fully
engaged.
Operating Instructions/Precautions
The transfer case provides four mode positions:
• 2H (Two-Wheel Drive High Range)
• 4H (Four-Wheel Drive High Range)
• N (Neutral)
• 4L (Four-Wheel Drive Low Range)
6
STARTING AND OPERATING 301

Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
WARNING!
You or others could be injured or killed if you leave the
vehicle unattended with the transfer case in the NEU-
TRAL (N) position without first fully engaging the
parking brake. The transfer case NEUTRAL (N) posi-
tion disengages both the front and rear drive shaft
from the powertrain, and will allow the vehicle to roll,
even if the automatic transmission is in PARK (or
manual transmission is in gear). The parking brake
should always be applied when the driver is not in the
vehicle.
Shift Positions
For additional information on the appropriate use of each
4WD system mode position, see the information below:
2H Position
This range is used for normal street and highway driving
on hard-surfaced roads.
4H Position
This range locks the front and rear driveshafts together,
forcing the front and rear wheels to rotate at the same
speed. This range (4H) provides additional traction for
loose, slippery road surfaces and should not be used on dry
pavement.
The “4WD Indicator Light” (located in the instrument
cluster) will illuminate when the transfer case is shifted
into the 4H position.
N (Neutral) Position
This range disengages the front and rear driveshafts from
the powertrain. It is to be used for flat towing behind
another vehicle. Refer to “Recreational Towing” in “Start-
ing And Operating” for further information.
4L Position
This range locks the front and rear driveshafts together,
forcing the front and rear wheels to rotate at the same
speed. This range (4L) provides additional traction and
maximum pulling power for loose, slippery road surfaces
only. Do not exceed 25 mph (40 km/h).
6
STARTING AND OPERATING 303

CAUTION!
Exceeding 25 mph (40 km/h) while the transfer case is
engaged in 4L may result in an engine overspeed
condition and engine damage.
The “4WD Indicator Light” (located in the instrument
cluster) will illuminate when the transfer case is shifted
into the 4L position.
NOTE: When in 4L, the “ESC Off Indicator Light” will
display in the instrument cluster.
Shifting Procedure
2H to 4H or 4H to 2H
Shifting between 2H and 4H can be made with the vehicle
stopped or in motion. With the vehicle in motion, the
transfer case will engage/disengage faster if you momen-
tarily release the accelerator pedal after completing the
shift. Apply a constant force when shifting the transfer case
lever.
4H to 4L or 4L to 4H
With the vehicle rolling at 2 to 3 mph (3 to 5 km/h), shift an
automatic transmission into NEUTRAL (N), or press the
clutch pedal on a manual transmission. While the vehicle is coasting at 2 to 3 mph (3 to 5 km/h), shift the transfer case
lever firmly to the desired position. Do not pause with the
transfer case in N (Neutral). Once the shift is completed,
place the automatic transmission into DRIVE or release the
clutch pedal on a manual transmission.
NOTE:
Shifting into or out of 4L is possible with the
vehicle completely stopped; however, difficulty may occur
due to the mating teeth not being properly aligned. Several
attempts may be required for clutch teeth alignment and
shift completion to occur. The preferred method is with the
vehicle rolling at 2 to 3 mph (3 to 5 km/h). Avoid
attempting to engage or disengage 4L with the vehicle
moving faster than 2 to 3 mph (3 to 5 km/h).
WARNING!
Failure to engage a transfer case position completely
can cause transfer case damage or loss of power and
vehicle control. You could have a collision. Do not
drive the vehicle unless the transfer case is fully
engaged.
304 STARTING AND OPERATING

Towing Requirements — Trailer Brakes
•Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible per-
sonal injury.
• An electronically actuated trailer brake controller is
required when towing a trailer with electronically actu-
ated brakes. When towing a trailer equipped with a
hydraulic surge actuated brake system, an electronic
brake controller is not required.
• Trailer brakes are recommended for trailers over
1,000 lbs (453 kg) and required for trailers in excess of
2,000 lbs (907 kg).
WARNING!
• Do not connect trailer brakes to your vehicle’s hy-
draulic brake lines. It can overload your brake sys-
tem and cause it to fail. You might not have brakes
when you need them and could have a collision.
• Towing any trailer will increase your stopping dis-
tance. When towing you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in a collision.
CAUTION!
If the trailer weighs more than 1,000 lbs (453 kg)
loaded, it should have its own brakes and they should
be of adequate capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake pedal
effort, and longer stopping distances.
Towing Requirements — Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stop lights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package will include a four–pin wiring
harness. Use a factory-approved trailer harness and con-
nector.
NOTE: Do not cut or splice wiring into the vehicles wiring
harness.
324 STARTING AND OPERATING

The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector. Refer
to the following illustration.
Towing Tips
Before setting out on a trip, practice turning, stopping and
backing the trailer in an area away from heavy traffic.If using a manual transmission vehicle for trailer towing,
all starts must be in first gear to avoid excessive clutch
slippage.
Automatic Transmission — If Equipped
Select the DRIVE range when towing. The transmission
controls include a drive strategy to avoid frequent shifting
when towing. However, if frequent shifting does occur
while in DRIVE, you can use the AutoStick shift control to
manually select a lower gear.
NOTE:
Using a lower gear while operating the vehicle
under heavy loading conditions will improve performance
and extend transmission life by reducing excessive shifting
and heat buildup. This action will also provide better
engine braking.
If you REGULARLY tow a trailer for more than 45 minutes
of continuous operation, then change the transmission
fluid and filter as specified for police, taxi, fleet, or frequent
trailer towing. Refer to the “Maintenance Plan” for the
proper maintenance intervals.
NOTE: Check the automatic transmission fluid level before
towing.

STARTING AND OPERATING 325

AutoStick — If Equipped
•When using the AutoStick shift control, select the high-
est gear that allows for adequate performance and
avoids frequent downshifts. For example, choose “4” if
the desired speed can be maintained. Choose “3” or “2”
if needed to maintain the desired speed.
• To prevent excess heat generation, avoid continuous
driving at high RPM. Reduce vehicle speed as necessary
to avoid extended driving at high RPM. Return to a
higher gear or vehicle speed when grade and road
conditions allow.
Electronic Speed Control — If Equipped
• Do not 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.
Cooling System
To reduce potential for engine and transmission overheat-
ing, take the following actions:
City Driving
When stopped for short periods of time, shift the transmis-
sion into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
