•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.
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.

The parking brake will release automatically when the
ignition switch is ON, the transmission is in Drive or
Reverse, the driver seat belt is buckled, and an attempt is
made to drive away.
To release the park brake manually, the ignition switch
must be in the ON/RUN position. Put your foot on the
brake pedal, then push the parking brake switch down
momentarily. You may hear a slight whirring sound from
the back of the car while the parking brake disengages.
You may also notice a small amount of movement in the
brake pedal. Once the parking brake is fully disengaged,
The BRAKE warning lamp in the instrument cluster and
the LED indicator on the switch will extinguish.
NOTE:When parking on a hill, it is important to turn the
front wheels toward the curb on a downhill grade and
away from the curb on an uphill grade. Apply the
parking brake before placing the shift lever in PARK, otherwise the load on the transmission locking mecha-
nism may make it difficult to move the shift lever out of
PARK. The parking brake should always be applied
whenever the driver is not in the vehicle.

ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system commonly referred to as ESC. This
system includes Anti-Lock Brake System (ABS), Traction
Control System (TCS), Brake Assist System (BAS), Hill
Start Assist (HSA), Electronic Roll Mitigation (ERM), and
Electronic Stability Control (ESC). These systems work
together to enhance both vehicle stability and control in
various driving conditions.
Your vehicle is also equipped with Trailer Sway Control
(TSC), Ready Alert Braking (RAB) and Rain Brake Sup-
port (RBS). Further, all vehicles equipped with a two-
speed power transfer unit have Hill Descent Control
(HDC) and some vehicles may also be equipped with
Selec Speed Control (SSC).
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) is designed to aid the
driver in maintaining vehicle control under adverse
braking conditions. The system operates with a separate
computer to modulate hydraulic pressure, to prevent
wheel lock-up and help avoid skidding on slippery
surfaces.
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.

Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system, 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. This feature remains
active even if TCS and ESC are in the “Partial Off” mode
or the “Full Off” mode. Refer to “Electronic Stability
Control (ESC)” in this section for further information.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. Thesystem 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
Anti-Lock Brake System (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive the
benefit of the system, you must apply continuous brak-
ing 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!(Continued)
road conditions. BAS cannot prevent collisions, in-
cluding those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. The capabilities of a BAS-equipped vehicle
must never be exploited in a reckless or dangerous
manner, which could jeopardize the user’s safety or
the safety of others.
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 evasive
driving maneuvers. It cannot prevent wheel lift due to
other factors, such as road conditions, leaving the road-
way, or striking objects or other vehicles.
NOTE:
ERM is disabled anytime the ESC is in “Full Off”
mode. Refer to Electronic Stability Control (ESC) for a
complete explanation of the available ESC modes.

ESC On — Two-Wheel Drive Vehicles And Four-Wheel
Drive Vehicles In 2WD And 4WD High Range
This is the normal operating mode for ESC when oper-
ating a two-wheel drive vehicle. It is also the normal
mode for operating a four-wheel drive vehicle in 2WD or
4WD HIGH range. The ESC system will be in “ESC On”
mode whenever the vehicle is started or the power
transfer unit (if equipped) is shifted out of 4WD LOW
range. This mode should be used for most driving
situations. ESC should only be turned to “Partial Off” or
“Full Off” for specific reasons as noted. Refer to “Partial
Off” and to “Full Off” for additional information.
Partial Off — Two-Wheel Drive Vehicles And Four-
Wheel Drive Vehicles In 2WD And 4WD High Range
The “Partial Off” mode is intended for driving in deep
snow, sand, or gravel. This mode raises the threshold for
TCS and ESC activation, which allows for more wheel
spin than what ESC normally allows.The “ESC Off” button is located in the lower 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 OFFbutton and
the ESC Off indicator light will turn off. This will restore
the normal “ESC On” mode of operation.
Page 521 of 764

WARNING!(Continued)
•Trailer Sway Control (TSC) is disabled when the
ESC system is in the Partial Offmode.
NOTE: To improve the vehicle’s traction when driving
with snow chains, or when starting off in deep snow,
sand, or gravel, it may be desirable to switch to the
“Partial Off” mode by momentarily pressing the “ESC
Off” button. 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.
Full Off — Four-Wheel Drive Vehicles In 4WD High
And 4WD Low Range
The “Full Off” mode is intended for off-highway and
off-road use when ESC stability features could inhibit
vehicle maneuverability due to trail conditions. The “ESC Off” button is located in the lower switch bank
above the climate control panel. To enter “Full Off”
mode, press and hold the “ESC Off” button for five
seconds while the vehicle is stopped with the engine
running. After five seconds, the
ESC Offindicator light
will illuminate and an “ESC Off” message will appear in
the odometer.
In this mode, ESC and TCS are turned off (except for the
“limited slip” feature described in the TCS section) until
the vehicle reaches a speed of 40 mph (64 km/h). At
speeds over 40 mph (64 km/h), the system automatically
switches to “Partial Off” mode, described above. When
the vehicle speed returns to less than 35 mph (56 km/h),
the ESC system will return to “Full Off” mode. The ESC
OFF indicator light is always illuminated when ESC is
off. To turn ESC on again, momentarily press the “ESC
Off” button. This will restore the normal “ESC On” mode
of operation.

Light” will flash, the engine power may be reduced and
you may feel the brakes being applied to individual
wheels to attempt to stop the trailer from swaying. TSC is
only active in the default “ESC On” mode. TSC can be
disabled by pressing the “ESC Off” switch and entering
“ESC Partial Off” mode. It is not active in the “ESC
Partial Off” or “ESC Full Off” modes. Refer to the ESC
portion of this section for an explanation of the different
ESC operating modes.
NOTE:TSC cannot stop all trailers from swaying.
