WARNING!(Continued)
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
30 mph (48 km/h), see an authorized dealer as soon as
possible to have the problem diagnosed and corrected.
The “ESC Activation/Malfunction Indicator Light” (lo-
cated in the instrument cluster) starts to flash as soon as the
tires lose traction and the ESC system becomes active. The
“ESC Activation/Malfunction Indicator Light” also flashes
when TCS is active. If the “ESC Activation/Malfunction Indicator Light” begins to flash during acceleration, ease
up on the accelerator and apply as little throttle as possible.
Be sure to adapt your speed and driving to the prevailing
road conditions.
NOTE:
•
The “ESC Activation/Malfunction Indicator Light” and
the “ESC OFF Indicator Light” come on momentarily
each time the ignition is turned ON.
• Each time the ignition is turned ON, the ESC system will
be on even if it was turned off previously.
• The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
The “ESC OFF Indicator Light” indicates the
customer has elected to have the Electronic Sta-
bility Control (ESC) in a reduced mode.

operating conditions), the transmission may use second
gear (rather than first gear) during launches, to mini-
mize wheel slippage.
• SAND: For off-road driving or use on surfaces with poor
traction, such as dry sand. The transmission is set to
provide maximum traction.
• MUD: For off-road driving or use on surfaces with poor
traction, such as roads covered by mud or wet grass.
• ROCK (Trailhawk only): This mode is only available in
4WD LOW range. The device sets the vehicle to maxi-
mize traction and allow the highest steering capacity for
off-road surfaces. This mode gives you the maximum
performance off-road. Use for low speed obstacles such
as large rocks, deep ruts, etc.
NOTE:
• Rock mode is only available on the vehicles equipped
with the Off-Road package.
• Activate the Hill Descent Control for steep downhill
control. See “Electronic Brake Control System” in this
section for further information.POWER STEERING
The electric power steering system will give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will vary its assist to provide light
efforts while parking and good feel while driving. If the
electric steering system experiences a fault that reduces
assist or prevents the vehicle from providing assist, you
will still have the ability to steer the vehicle manually.

TIRE QUALITY GRADES
The following tire grading categories were established
by the National Highway Traffic Safety Administration.
The specific grade rating assigned by the tire’s manu-
facturer in each category is shown on the sidewall of the
tires on your vehicle.
All passenger vehicle tires must conform to Federal
safety requirements in addition to these grades.
Treadwear
The Treadwear grade is a comparative rating, based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded 150 would wear one and one-half
times as well on the government course as a tire graded
100. The relative performance of tires depends upon the
actual conditions of their use, however, and may depart
significantly from the norm due to variations in driving
habits, service practices, and differences in road charac-
teristics and climate.
Traction Grades
The Traction grades, from highest to lowest, are AA, A,
B, and C. These grades represent the tire’s ability to stopon wet pavement, as measured under controlled condi-
tions on specified government test surfaces of asphalt
and concrete. A tire marked C may have poor traction
performance.
