again, momentarily depress the ESP OFF switch. This
will restore the normal “ESP On” mode of operation.
NOTE:The ESP system will change to “Partial Off”
mode if the vehicle speed exceeds 40 mph (64 km/h).
After the vehicle speed is reduced below 35 mph (56
km/h), the ESP system will return to “Full Off” mode.
NOTE: The “ESP OFF” message will display and the
audible chime will sound when the shift lever is placed in
the PARK position from any position other than PARK,
and then moved out of the PARK position. This will
occur even if the message was previously cleared.WARNING!
With the ESP switched off, the enhanced vehicle
stability offered by ESP and ERM are unavailable. In
an emergency evasive maneuver, the ESP and ERM
systems will not engage to assist in maintaining
stability. The “Full Off” ESP mode is intended for
off-road use only.
4L Range (4WD Models)
ESP Off
This is the normal operating mode for ESP in 4L range.
Whenever the vehicle is started in 4L range, or the
transfer case (if equipped) is shifted from 4H range or
NEUTRAL to 4L range, the ESP system will be in this
mode. In 4L range, ESP and TCS, except for the “limited
slip” feature described in the TCS section, are turned off
until the vehicle reaches a speed of 40 mph (48 km/h). At
112 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

40 mph (48 km/h), the normal ESP stability function
returns but TCS remains off. When the vehicle speed
drops below 35 mph (40 km/h), the ESP system shuts off.
ESP is off at low vehicle speeds in 4L range so that it will
not interfere with off-road driving, but the ESP function
returns to provide the stability feature at speeds above 40
mph (48 km/h). The ESP/TCS Indicator Light will al-
ways be illuminated in 4L range when ESP is off.
NOTE:The “ESP OFF” message will display and the
audible chime will sound when the shift lever is placed in
the PARK position from any position other than PARK,
and then moved out of the PARK position. This will
occur even if the message was previously cleared.WARNING!
With the ESP switched off, the enhanced vehicle
stability offered by ESP and ERM are unavailable. In
an emergency evasive maneuver, the ESP and ERM
systems will not engage to assist in maintaining
stability. The “Full Off” mode is intended for off-
road use only.
Disabling ESP for Modified Vehicles (4WD Models
Only)
Vehicles modified with larger tires and/or suspension
lifts may experience early ESP activations as compared to
a non-modified production vehicle depending on lift
size, tire size, suspension changes and/or driving habits.
If early ESP activations are experienced while driving a
modified vehicle, the additional ability to permanently
turn off ESP is available. A steering wheel/ESP button

will flash anytime the ESP or TCS is active and helping to
improve vehicle stability. If the ESP/TCS Indicator Light
is on solid, the ESP system has been turned off by the
driver or a temporary condition exists that will not allow
full ESP function.
27. O/D (Overdrive) Off Indicator LightThis light will illuminate when the O/D OFF
button has been selected. The O/D OFF button is
located on the center console.
28. Sway Bar Indicator Light — If Equipped This light will illuminate when the front sway
bar is disconnected.
29. Electronic Stability Program (ESP)/Brake Assist
System (BAS) Warning Light The ESP/BAS Warning Light in the instrument
cluster comes on when the ignition switch is
turned to the ON position. The light should go out with the engine running. If the ESP/BAS Warning
Light comes on continuously with the engine running, a
malfunction has been detected in either the ESP or the
BAS system. If this light stays illuminated, have the ESP
and BAS checked at your authorized dealer as soon as
possible. Refer to “Electronic Brake Control System” in
Section 3 for more information.
30. Electronic Throttle Control (ETC) Warning Light —
If Equipped
This light informs you of a problem with the
Electronic Throttle Control System. If a prob-
lem is detected while the engine is running, the
light will either stay on or flash depending on
the nature of the problem. Cycle the ignition key when
the vehicle is safely and completely stopped and the shift
lever is placed in the PARK position. The light should
turn off. If the light remains on with the engine running,
your vehicle will usually be drivable, however, see your
authorized dealer for service as soon as possible.

Overdrive can be locked out by pressing the O/D OFF
switch located on the center console. The O/D OFF
indicator light (on the switch) will illuminate to show
that the switch has been activated. When the indicator
light is on, Overdrive is locked out. Pressing the switch a
second time restores the Overdrive function. The lockout
feature is useful when towing a trailer or carrying a
heavy load.
2 (Second)
For moderate grades and to assist braking on dry pave-
ment or in mud and snow. Begins from a stop in low gear
with automatic upshift to 2nd gear. Will not shift to 3rd.
1 (First)
For hard pulling at low speeds in mud, sand, snow, or on
steep grades. Begins and stays in low gear with no
upshift. Provides engine compression braking at low
speeds.CAUTION!
•Before moving the shift lever out of PARK, you
must turn the ignition from LOCK so the steering
wheel and shift lever are released. Otherwise,
damage to steering column or shift lever could
result.
•Never race the engine with the brakes on and the
vehicle in gear, and never hold the vehicle on an
incline without applying the brakes. These prac-
tices can overheat and damage the transmission.
•When “rocking” a stuck vehicle by moving be-
tween DRIVE and REVERSE, do not spin the
wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.
284 STARTING AND OPERATING

If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:Increased noise levels at the end of the steering
wheel travel are considered normal and do not indicate
that there is a problem with the power steering system.
Upon initial start-up in cold weather, the power steering
pump may make noise for a short amount of time. This is
due to the cold, thick fluid in the steering system. This
noise should be considered normal, and it does not in any
way damage the steering system.WARNING!
Continued operation with reduced power steering
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
CAUTION!
Prolonged operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and it should be avoided when
possible. Damage to the power steering pump may
occur.
