If the Steering icon is displayed and the “SERVICE
POWER STEERING” message is displayed the EVIC
screen, this indicates the vehicle needs to be taken to the
dealer for potential service. Refer to “Electronic Vehicle
Information (EVIC)” in “Understanding Your Instrument
Panel” for further information.
NOTE:
•Even if the power steering assistance is no longer
operational, it is still possible to steer the vehicle.
Under these conditions there will be a substantial
increase in steering effort, especially at low speeds and
during parking maneuvers.
•If the condition persists, see your authorized dealer for
service.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system. This system includes Anti-Lock
Brake System (ABS), Brake Assist System (BAS), TractionControl System (TCS), Electronic Roll Mitigation (ERM),
Trailer Sway Control (TCS), Hill Start Assist (HSA), Brake
Lock Differential (BLD), and Electronic Stability Control
(ESC). These systems work together to enhance both
vehicle stability and control in various driving condi-
tions.
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under most
braking conditions. The system automatically prevents
wheel lock, reduces stop distance, and enhances vehicle
control during stop.
When the vehicle is driven over 7 mph (11 km/h), you
may also hear a slight clicking sound as well as some
related motor noises. These noises are the system per-
forming its self-check cycle to ensure that the ABS is
working properly. This self-check occurs each time the
vehicle is started and accelerated past 7 mph (11 km/h).

STARTING AND OPERATING 415
WARNING! (Continued)
•The ABS cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that af-
forded by the condition of the vehicle brakes and
tires or the traction afforded.
•The ABS cannot prevent collisions, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro-
planing.
•The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous
manner, which could jeopardize the user’s safety
or the safety of others.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
Anti-Lock Brake Warning Light
The “Anti-Lock Brake Warning Light” moni-
tors the ABS. The 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 “ABS 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 system will
continue to operate normally if the “Brake System Warn-
ing Light” is not on.
If the “ABS Warning Light” is on, the brake system
should be serviced as soon as possible to restore the
benefits of anti-lock brakes. If the “ABS Warning Light”
does not come on when the ignition switch is turned to
the ON position, have the light repaired as soon as
possible.
5
STARTING AND OPERATING 417
If both the “Brake System Warning Light” and the “ABS
Warning Light” remain on, the ABS and Electronic Brake
Force Distribution (EBD) systems are not functioning.
Immediate repair to the ABS system is required.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
ABS. Applying the brakes very quickly results in the best
BAS assistance. To receive the benefit of the system, you
must apply continuous braking pressure during the
stopping sequence, (do not “pump” the brakes). Do not
reduce brake pedal pressure unless braking is no longer
desired. Once the brake pedal is released, the BAS is
deactivated.
WARNING!
The BAS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded by prevailing road conditions. BAS
cannot prevent collisions, including those resulting
from excessive speed in turns, driving on very slip-
pery surfaces, or hydroplaning. The capabilities of a
BAS-equipped vehicle must never be exploited in a
reckless or dangerous manner, which could jeopar-
dize the user’s safety or the safety of others.
Traction Control System (TCS)
The system monitors the amount of wheel spin at each
wheel by using individual wheel speed sensors. If wheel
spin is detected, brake pressure is applied to the slipping
wheel(s) and engine power is reduced to provide en-
hanced acceleration and stability. A feature of the TCS
functions similar to a limited slip differential and controls
418 STARTING AND OPERATING
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. This feature remains active even if TCS
and ESC are in the “Partial Off” mode. Refer to “Elec-
tronic Stability Control (ESC)” in this section for more
information.
Electronic Roll Mitigation (ERM)
This system anticipates the potential for wheel lift by
monitoring the driver ’s steering wheel input and the
speed of the vehicle. When ERM determines that the rate
of change of the steering wheel angle and vehicle’s speed
are sufficient to potentially cause wheel lift, it then
applies the appropriate brake and may also reduce
engine power to lessen the chance that wheel lift will
occur. ERM will only intervene during very severe or
evasive driving maneuvers. ERM can only reduce the
chance of wheel lift occurring during severe or evasivedriving maneuvers. It cannot prevent wheel lift due to
other factors, such as road conditions, leaving the road-
way, or striking objects or other vehicles.
WARNING!
Many factors, such as vehicle loading, road condi-
tions, and driving conditions, influence the chance
that wheel lift or rollover may occur. ERM cannot
prevent all wheel lift or rollovers, especially those
that involve leaving the roadway or striking objects
or other vehicles. The capabilities of an ERM-
equipped vehicle must never be exploited in a reck-
less or dangerous manner, which could jeopardize
the user’s safety or the safety of others.

STARTING AND OPERATING 419
WARNING! (Continued)
•HSA is not a parking brake. Always apply the
parking brake fully when leaving your vehicle.
Also, be certain to leave the transmission in PARK.
•Failure to follow these warnings may cause the
vehicle to roll down the incline and could collide
with another vehicle, object or person, and cause
serious or fatal injury. Always remember to use the
parking brake while parking on a hill and that the
driver is responsible for braking the vehicle.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for over-steering and under-steering the vehicle by
applying the brake of the appropriate wheel. Engine
power may also be reduced to help the vehicle maintain
the desired path.ESC reduces engine torque and applies brake pressure to
select individual wheels to mitigate vehicle under-steer
and vehicle over-steer. The system uses engine torque
reduction along with individual wheel brake pressure to
correct under-steer and over-steer conditions.
•Over-steer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Under-steer - when the vehicle is turning less than
appropriate for the steering wheel position.
ESC Off Indicator Light
The “ESC OFF Indicator Light” indicates the
Electronic Stability Control (ESC) is off.
In some cases, when accelerating from stop on steep
grades, it may be beneficial to turn off ESC. Once the
grade ascent is complete, ESC can be turned on again.
5
STARTING AND OPERATING 423
WARNING!
•The Electronic Stability Control (ESC) cannot pre-
vent the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions.
•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.
•The capabilities of an ESC-equipped vehicle must
never be exploited in a reckless or dangerous
manner, which could jeopardize the user’s safety
or the safety of others.
ESC Activation/Malfunction Indicator Light
The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is turned to the ONposition. It should go out with the engine running. The
“ESC Activation/Malfunction Indicator Light” will flash
to indicate the system is actively correcting an undesir-
able vehicle condition. This includes Yaw control, traction
control, and trailer sway control. If the lamp remains
solid under normal driving conditions, your vehicle
should be serviced at an authorized dealer.
The “ESC Activation/Malfunction Indicator Light” 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 the Traction Control System (TCS) or trailer
sway 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.
424 STARTING AND OPERATING
NOTE:
•The “ESC Off Indicator Light” and the “ESC
Activation/Malfunction Indicator Light” come on mo-
mentarily each time the ignition switch 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 may 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.
ESC Operating Modes
The ESC system has two available operating modes.Full On
This is the normal operating mode for ESC. Whenever
the vehicle is started the system will be in this mode. This
mode should be used for most driving situations. ESC
should only be turned to “Partial Off” for specific reasons
as noted. Refer to “Partial Off” for additional informa-
tion.
Partial Off
The “ESC Off” button is located in the switch bank above
the climate control. To enter the “Partial Off” mode,
momentarily press the “ESC Off” button and the “ESC
Off Indicator Light” will illuminate. To turn the ESC on
again, momentarily press the “ESC Off” button and the
“ESC Off Indicator Light” will turn off. This will restore
the normal “ESC On” mode of operation.

STARTING AND OPERATING 425
WARNING!
•When inPartial Off mode, the TCS functionality
of ESC, (except for the limited slip feature de-
scribed in the TCS section), has been disabled and
the ESC Off Indicator Light will be illuminated.
When in Partial Off mode, the engine power
reduction feature of TCS is disabled, and the
enhanced vehicle stability offered by the ESC
system is reduced.
•Trailer Sway control (TSC) is disabled when the
ESC system is in the Partial Offmode. NOTE:
When driving with snow chains, or when start-
ing off in deep snow, sand, or gravel, it may be desirable
to allow more wheel spin when starting off in snow, mud,
sand, gravel, or when using tire chains. This can be
accomplished by momentarily pressing the ESC off”
button to enter partial mode “Partial Off” mode. Once the
situation requiring “Partial Off” mode is overcome, turn
ESC back on by momentarily pressing the “ESC Off”
button. This may be done while the vehicle is in motion.
