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 Dis-
abled Vehicle” in “What To Do In Emergen-
cies” for further information.
DRIVE (D)
This range should be used for most city and
highway driving. It provides the smoothest up-
shifts and downshifts, and the best fuel
economy. The transmission automatically up-
shifts through underdrive first, second, third,
and fourth gears, direct fifth gear and overdrive
sixth gear. The DRIVE position provides opti-
mum driving characteristics under all normal
operating conditions.
When frequent transmission shifting occurs
(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 shift control(refer to “AutoStick (Six-Speed Automatic
Transmission)” in this section for further infor-
mation) to select a lower gear. Under these
conditions, using a lower gear will improve
performance and extend transmission life by
reducing excessive shifting and heat buildup.
If the transmission temperature exceeds normal
operating limits, the transmission controller will
modify the transmission shift schedule and ex-
pand the range of torque converter clutch en-
gagement. This is done to prevent transmission
damage due to overheating. If the transmission
becomes extremely hot, the “Transmission
Temperature Warning Light” may illuminate and
the transmission may operate differently until
the transmission cools down.
During very cold temperatures (-4°F [-20°C] or
below), transmission operation may be modified
depending on engine and transmission tem-
perature as well as vehicle speed. Normal op-
eration will resume once the transmission tem-
perature has risen to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored electroni-
cally for abnormal conditions. If a condition isdetected that could result in transmission dam-
age, Transmission Limp Home Mode is acti-
vated. In this mode, the transmission remains in
fourth 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 transmission.
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 switch 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 transmis-
sion will return to normal operation.

NOTE:
Even if the transmission can be reset, we
recommend that you visit your authorized
dealer at your earliest possible conve-
nience. 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.
Overdrive Operation
The automatic transmission includes an elec-
tronically controlled Overdrive (sixth gear). The
transmission will automatically shift into Over-
drive if the following conditions are present:
•The gear selector is in the DRIVE position.
•The transmission fluid has reached an ad-
equate temperature.
•The engine coolant has reached an ad-
equate temperature.
•The vehicle speed is sufficiently high.
•The driver is not heavily pressing the
accelerator.Torque Converter Clutch
A feature designed to improve fuel economy
has been included in the automatic transmis-
sion on your vehicle. A clutch within the torque
converter engages automatically at calibrated
speeds. This may result in a slightly different
feeling or response during normal operation in
the upper gears. When the vehicle speed drops
or during some accelerations, the clutch auto-
matically disengages.
NOTE:
Engagement of the torque converter clutch
is inhibited at very cold temperatures. Be-
cause the engine speed is higher when the
torque converter clutch is not engaged, it
may seem as if the transmission is not
shifting into Overdrive when cold. This is
normal. The torque converter clutch will
function normally once the transmission is
sufficiently warm.
Continuously Variable Automatic
Transmission (CVT) — If Equipped
The transmission gear position display (located
in the instrument cluster) indicates the transmis-
sion gear range. You must press the brakepedal 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.
NOTE:
The Continuously Variable Automatic Trans-
mission (CVT) changes ratios in a continu-
ous manner. This may sometimesfeelas if
it is slipping, but this is normal and does not
harm anything.
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 posi-
tions. 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
manually select from a set of predefined trans-
mission gear ratios, and will display the current
gear in the instrument cluster as 1, 2, 3, etc.

selected gear until another upshift or downshift
is chosen, except as described below:
•The transmission will automatically upshift
when necessary to prevent engine over-
speed.
•The transmission will automatically downshift
as the vehicle slows (to prevent engine lug-
ging) 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.
•If a requested downshift would cause the
engine to overspeed, that shift will not occur.
•Transmission shifting will be more noticeable
when AutoStick is engaged.
•Heavy Anti-Lock Brake System (ABS) appli-
cation will disengage AutoStick mode.
•The system may revert to automatic shift
mode if a fault or overheat condition is
detected.To disengage AutoStick mode, hold the gear
selector to the right (+) until “D” is 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 brak-
ing 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 — IF EQUIPPED
This feature provides full time, on-demand,
four–wheel drive (4WD).Where one or more wheels have wheel spin or
if additional traction is needed in sand, deep
snow, or loose traction surfaces, activate the
“4WD LOCK” switch by pulling up once and
releasing. This locks the center coupling allow-
ing more torque to be sent to the rear wheels.
The “4WD Indicator Light” will come on in the
cluster. This can be done on the fly, at any
vehicle speed. To deactivate, simply pull on the
switch one more time. The “4WD Indicator
Light” will then go out.

CAUTION!(Continued)
water. Water can cause permanent damage
to engine, driveline or other vehicle compo-
nents and your brakes will be less effective
once wet and/or muddy.
Before You Cross Any Type Of Water
As you approach any type of water, you need to
determine if you can cross it safely and respon-
sibly. If necessary, get out and walk through the
water or probe it with a stick. You need to be
sure of its depth, approach angle, current and
bottom condition. Be careful of murky or muddy
waters; check for hidden obstacles. Make sure
you will not be intruding on any wildlife, and you
can recover the vehicle if necessary. The key to
a safe crossing is the water depth, current and
bottom conditions. On soft bottoms, the vehicle
will sink in, effectively increasing the water level
on the vehicle. Be sure to consider this when
determining the depth and the ability to safely
cross.Crossing Puddles, Pools, Flooded Areas
Or Other Standing Water
Puddles, pools, flooded or other standing water
areas normally contain murky or muddy waters.
These water types normally contain hidden
obstacles and make it difficult to determine an
accurate water depth, approach angle, and
bottom condition. Murky or muddy water holes
are where you want to hook up tow straps prior
to entering. This makes for a faster, cleaner and
easier vehicle recovery. If you are able to deter-
mine you can safely cross, than proceed using
the low and slow method.
CAUTION!
Muddy waters can reduce the cooling sys-
tem effectiveness by depositing debris onto
the radiator.
After Driving Off-RoadOff-road operation puts more stress on your
vehicle than does most on-road driving. After
going off-road, it is always a good idea to check
for damage. That way you can get any problemstaken care of right away and have your vehicle
ready when you need it.
•Completely inspect the underbody of your
vehicle. Check tires, body structure, steering,
suspension, and exhaust system for dam-
age.
•Inspect the radiator for mud and debris and
clean as required.
•Check threaded fasteners for looseness, par-
ticularly on the chassis, drivetrain compo-
nents, steering, and suspension. Retighten
them, if required, and torque to the values
specified in the Service Manual.
•Check for accumulations of plants or brush.
These things could be a fire hazard. They
might hide damage to fuel lines, brake hoses,
axle pinion seals, and propeller shafts.
•After extended operation in mud, sand, wa-
ter, or similar dirty conditions, have the radia-
tor, fan, brake rotors, wheels, brake linings,
and axle yokes inspected and cleaned as
soon as possible.

WARNING!(Continued)
your vehicle harder to control. You could
have a collision. Have the vehicle checked
immediately.
ELECTRONIC BRAKE
CONTROL SYSTEM
Your vehicle is equipped with an advanced
Electronic Brake Control system (EBC). This
system includes Electronic Brake Force Distri-
bution (EBD), Anti-Lock Brake System (ABS),
Brake Assist System (BAS), Hill Start Assist
(HSA), Traction Control System (TCS), Elec-
tronic Stability Control (ESC), and Electronic
Roll Mitigation (ERM). These systems work
together to enhance both vehicle stability and
control in various driving conditions.
Your vehicle may also be equipped with Hill
Descent Control (HDC).
Electronic Brake Force Distribution
(EBD)
This function manages the distribution of the
braking torque between the front and rear axles
by limiting braking pressure to the rear axle.
This is done to prevent overslip of the rear
wheels to avoid vehicle instability, and to pre-
vent the rear axle from entering ABS before the
front axle.
Brake System Warning LightThe red “Brake System Warning Light” will turn
on when the ignition switch is turned to the ON
position and may stay on for as long as four
seconds.
If the “Brake System Warning Light” remains on
or comes on while driving, it indicates that the
brake system is not functioning properly and
that immediate service is required. If the “Brake
System Warning Light” does not come on when
the ignition switch is turned to the ON position,
have the light repaired as soon as possible.
Anti-Lock Brake System (ABS)The Anti-Lock Brake System (ABS) provides
increased vehicle stability and brake perfor-
mance under most braking conditions. The sys-
tem automatically prevents wheel lock, and
enhances vehicle control during braking.
The ABS performs a self-check cycle to ensure
that the ABS is working properly each time the
vehicle is started and driven. During this self-
check, you may hear a slight clicking sound as
well as some related motor noises.
ABS is activated during braking when the sys-
tem detects one or more wheels begins to lock.
Road conditions such as ice, snow, gravel,
bumps, railroad tracks, loose debris, or panic
stops may increase the likelihood of ABS acti-
vation(s).
You also may experience the following when
ABS activates:
•The ABS motor noise (it may continue to run
for a short time after the stop).
•The clicking sound of solenoid valves.
•Brake pedal pulsations.

four times within twenty seconds. The “ESC
Off Indicator Light” should turn on and turn
off two times.
7. Rotate the steering wheel back to center and
then an additional slighty more than one-half
turn to the right.
8. Turn the ignition switch to the OFF position
and then back to the ON position. If the
sequence was completed properly, the “ESC
Off Indicator Light” will blink several times to
confirm HSA is disabled.
9. Repeat these steps if you want to return this
feature to its previous setting.
Traction Control System (TCS)This system monitors the amount of wheel spin
of each of the driven wheels. If wheel spin is
detected, the TCS may apply brake pressure to
the spinning wheel(s) and/or reduce engine
power to provide enhanced acceleration and
stability. A feature of the TCS, Brake Limited
Differential (BLD), functions similar to a limited
slip differential and controls the wheel spin
across a driven axle. If one wheel on a drivenaxle is spinning faster than the other, the sys-
tem will apply the brake of the spinning wheel.
This will allow more engine torque to be applied
to the wheel that is not spinning. BLD may
remain enabled even if TCS and ESC are in a
reduced mode.
Electronic Stability Control (ESC)This system enhances directional control and
stability of the vehicle under various driving
conditions. ESC corrects for over-steering or
under-steering of the vehicle by applying the
brake of the appropriate wheel to assist in
counteracting the over-steering or under-
steering condition. Engine power may also be
reduced to help the vehicle maintain the desired
path. ESC uses sensors in the vehicle to deter-
mine the vehicle path intended by the driver and
compares it to the actual path of the vehicle.
When the actual path does not match the
intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting the
over-steer or under-steer condition
•Oversteer - when the vehicle is turning more
than appropriate for the steering wheel posi-
tion.•Understeer - when the vehicle is turning less
than appropriate for the steering wheel
position.
WARNING!
•The Electronic Stability Control (ESC) can-
not prevent the natural laws of physics
from acting on the vehicle, nor can it
increase the traction afforded by prevailing
road conditions.
•ESC cannot prevent accidents, including
those resulting from excessive speed in
turns, driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent
collisions resulting from loss of vehicle
control due to inappropriate driver input for
the conditions. Only a safe, attentive, and
skillful driver can prevent collisions.

WARNING!(Continued)
Light” will be illuminated. When in “Partial
Off” mode, the engine power reduction of
TCS is disabled, and the enhanced vehicle
stability offered by the ESC system is re-
duced. Trailer Sway control (TSC) (if
equipped) is disabled when the ESC system
is in the"Partial Off"mode.
Full Off (Four-Wheel Drive Models Only)
This mode is intended for off-highway or off-
road use when ESC stability features could
inhibit vehicle maneuverability due to trail con-
ditions. This mode is entered by pushing and
holding the “ESC Off” switch for five seconds
when the vehicle is stopped and the engine is
running. After five seconds, the"ESC OFF
Indicator Light"will illuminate and the “ESC
OFF” message will appear in the odometer.
Push and release the Trip Odometer button
located on the instrument cluster to clear this
message.
In this mode, ESC and TCS, except for the
“limited slip” feature described in the TCS sec-tion, are turned off until the vehicle reaches a
speed of 35 mph (56 km/h). At 35 mph
(56 km/h), the system returns to “Partial Off”
mode, as described above. TCS remains off.
When the vehicle speed drops below 30 mph
(48 km/h), the ESC system shuts off. ESC is
deactivated at low vehicle speeds so that it will
not interfere with off-road driving however, ESC
function returns to provide the stability feature
at speeds above 35 mph (56 km/h). The"ESC
OFF Indicator Light"will always be illuminated
when ESC is off.
To turn ESC on again, momentarily push the
“ESC Off” switch. This will restore the “ESC On”
mode of operation.
NOTE:
The “ESC OFF” message will display and an
audible chime will sound when the gear
selector is placed into the PARK position
from any other position, and then moved out
of the PARK position. This will occur even if
the message was previously cleared.
WARNING!
In the"Full Off"mode, the engine torque
reduction and stability features are disabled.
In an emergency evasive maneuver, the
ESC system will not engage to assist in
maintaining stability. “ESC Off” mode is in-
tended for off-highway or off-road use only.
ESC Activation/Malfunction Indicator Light
And ESC OFF Indicator Light
The “ESC Activation/Malfunction
Indicator Light” in the instrument
cluster will come on when the igni-
tion switch is cycled to the ON/
RUN position. It should go out with
the engine running. If the “ESC
Activation/Malfunction Indicator Light” comes
on continuously with the engine running, a
malfunction has been detected in the ESC
system. If this light remains on after several
ignition cycles, and the vehicle has been driven
several miles (kilometers) at speeds greater
than 30 mph (48 km/h), see your authorized

Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.Tighten the lug nuts/bolts in a star pattern until
each nut/bolt has been tightened twice.After 25 miles (40 km) check the lug nut/bolt
torque to be sure that all the lug nuts/bolts are
properly seated against the wheel.
WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the lug nuts fully until the
vehicle has been lowered. Failure to follow
this warning may result in personal injury.
JACKING AND TIRE
CHANGING
WARNING!
•Do not attempt to change a tire on the side
of the vehicle close to moving traffic. Pull
far enough off the road to avoid the danger
of being hit when operating the jack or

wheel nuts. When reinstalling the original
wheel, properly align the wheel cover to the
valve stem, place the wheel cover onto the
wheel, then install the wheel nuts.
6. Lower the vehicle by turning the jack screw
to the left.
7. Finish tightening the lug nuts. Push down on
the wrench while at the end of the handle for
increased leverage. Tighten the lug nuts in a
star pattern until each nut has been tight-
ened twice. Refer to “Torque Specifications”
in this section for the correct lug nut torque.
If you doubt that you have tightened the nutscorrectly, have them checked with a torque
wrench by your authorized dealer or service
station.
8. Remove the wheel blocks and lower the jack
until it is free. Release the parking brake.
Reassemble the lug wrench to the jack as-
sembly and stow it in the spare tire area.
Secure the assembly using the means pro-
vided.
WARNING!
A loose tire or jack thrown forward in a
collision or hard stop could endanger the
occupants of the vehicle. Always stow the
jack parts and the spare tire in the places
provided.
9. Place the deflated (flat) tire in the cargo
area,have the tire repaired or replaced as
soon as possible.
WARNING!
A loose tire thrown forward in a collision or
hard stop could injure the occupants in the
