4WD Low Indicator Light — If Equipped
Yellow TelltaleLight What It Means
4WD Low Indicator Light
This light alerts the driver that the vehicle is in the four-wheel drive LOW mode. The front and
rear driveshafts are mechanically locked together forcing the front and rear wheels to rotate at
the same speed. Low range provides a greater gear reduction ratio to provide increased torque at
the wheels.
Refer to “Four-Wheel Drive Operation — If Equipped” in “Starting And Operating” for further
information on four-wheel drive operation and proper use.

WARNING!(Continued)
•The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous manner
that could jeopardize the user ’s safety or the safety of
others.
ABS is designed to function with the OEM tires. Modifica-
tion may result in degraded ABS performance.
Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake Warning Light” will turn on
when the ignition is turned to the ON mode and may stay
on for as long as four seconds.
If the “Anti-Lock Brake Warning Light” remains on or
comes on while driving, it indicates that the anti-lock
portion of the brake system is not functioning and that
service is required. However, the conventional brake sys-
tem will continue to operate normally if the “Brake System
Warning Light” is not on.
If the “Anti-Lock Brake Warning Light” is on, the brake
system should be serviced as soon as possible to restore the
benefits of anti-lock brakes. If the “Anti-Lock Brake Warn-
ing Light” does not come on when the ignition is turned to
the ON mode, have the light repaired as soon as possible.
Electronic Brake Control System
Your vehicle is equipped with an advanced Electronic
Brake Control system (EBC). This system includes Elec-
tronic Brake Force Distribution (EBD), Anti-Lock Brake
System (ABS), Brake Assist System (BAS), Hill Start Assist
(HSA), Traction Control System (TCS), Electronic 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 prevent
the rear axle from entering ABS before the front axle.
Brake System Warning Light
The red “Brake System Warning Light” will turn on when
the ignition is turned to the ON mode and may stay on for
as long as four seconds.

3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more than one-halfturn to the left.
6. Push the “ESC Off” button located in the lower switch bank below the climate control 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 to the OFF mode and then back to ON. 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 driven axle is spinning faster than the other, the
system 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 oversteering or understeering of the vehicle by apply-
ing the brake of the appropriate wheel(s) to assist in
counteracting the oversteer or understeer condition. En-
gine power may also be reduced to help the vehicle
maintain the desired path.
ESC uses sensors in the vehicle to determine 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 oversteer or understeer
condition.
•
Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
134 SAFETY

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 maneu-
verability due to trail conditions. 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, theESC 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 section, 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 intended 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 ignition is turned to the ON mode. 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

SAFETY 137

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, third, and fourth
gears, direct fifth gear and overdrive sixth gear. The DRIVE
position provides optimum 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, traveling 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 information) 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 transmis-
sion shift schedule and expand the range of torque converter
clutch engagement. This is done to prevent transmission
damage due to overheating. If the transmission becomes
extremely hot, the “Transmission Temperature WarningLight” 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 temperature as well as vehicle
speed. Normal operation will resume once the transmis-
sion temperature has risen to a suitable level.
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 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 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.6

3. Turn the ignition switch to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is nolonger 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.
Overdrive Operation
The automatic transmission includes an electronically con-
trolled Overdrive (sixth gear). The transmission will auto-
matically shift into Overdrive if the following conditions
are present:
• The gear selector is in the DRIVE position.
• The transmission fluid has reached an adequate tem-
perature. •
The engine coolant has reached an adequate tempera-
ture.
• 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 transmission 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 automatically disengages.
NOTE: Engagement of the torque converter clutch is in-
hibited at very cold temperatures. Because 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 transmis-
sion is sufficiently warm.

DRIVE (D)
This range should be used for most city and highway
driving. It provides the best fuel economy. The DRIVE
position provides optimum 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, traveling into strong head winds, or while
towing a heavy trailer), use the AutoStick shift control
(refer to “AutoStick (CVT)” in this section for further
information) to select a lower gear ratio. Under these
conditions, using a lower gear ratio will improve perfor-
mance and extend transmission life by reducing excessive
shifting and heat buildup.During sustained high speed driving or trailer
towing up long grades on hot days, the auto-
matic transmission oil may become too hot. If
this happens, the transmission overheat indicator
light will come on, and the vehicle will slow slightly until
the transmission cools down enough to allow a return to
the requested speed. This is done to prevent transmission
damage due to overheating. If the high speed is main-
tained, the overheating may reoccur, as before, in a cyclic
fashion.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 allowing
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.

212 STARTING AND OPERATING

After Driving Off-Road
Off-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 problems taken 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 damage.
• Inspect the radiator for mud and debris and clean as
required.
• Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. 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, water, or similar
dirty conditions, have the radiator, fan, brake rotors,
wheels, brake linings, and axle yokes inspected and
cleaned as soon as possible.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a wheel
imbalance and freeing the wheels of it will correct the
situation.
