216 GETTING TO KNOW YOUR INSTRUMENT PANEL
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic
brake systems. If either of the two hydraulic
systems loses normal capability, the remaining
system will still function. However, there will
be some loss of overall braking effectiveness. This will be
evident by increased pedal travel during application and
greater pedal force required to slow or stop the vehicle. In
addition, if the malfunction is caused by a leak in the
hydraulic system, the “Brake Warning Light” will turn on
as the brake fluid level drops in the master cylinder.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine OFF) the
brakes will still function. However, the effort required to
brake the vehicle will be much greater than that required
with the power system operating.
WARNING!
•Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting
or riding on the brake pedal can result in abnor-
mally high brake temperatures, excessive lining
wear, and possible brake damage. You would not
have your full braking capacity in an emergency.
•Driving a vehicle with the “Brake Warning Light”
on is dangerous. A significant decrease in braking
performance or vehicle stability during braking
may occur. It will take you longer to stop the
vehicle or will make your vehicle harder to control.
You could have a collision. Have the vehicle
checked immediately.

SAFETY 223
WARNING!
•Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need to
slow down or stop.
•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 afforded
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 hydroplaning.
•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.
CAUTION!
The ABS is subject to possible detrimental effects of
electronic interference caused by improperly in-
stalled aftermarket radios or telephones.
NOTE:During severe braking conditions, a pulsing sen-
sation may occur and a clicking noise will be heard. This
is normal, indicating that the ABS is functioning.
•Do not “ride” the brakes by resting your foot on the
pedal. This could overheat the brakes and result in
unpredictable braking action, longer stopping dis-
tances, or brake damage.
•When descending mountains or hills, repeated braking
can cause brake fade with loss of braking control.
Avoid repeated heavy braking by downshifting the
transmission or locking out overdrive whenever pos-
sible.
226 SAFETY
•Engines may idle at higher speeds during warm-up,
which could cause rear wheels to spin and result in
loss of vehicle control. Be especially careful while
driving on slippery roads, in close-quarter maneuver-
ing, parking, or stopping.
•Do not drive too fast for road conditions, especially
when roads are wet or slushy. A wedge of water can
build up between the tire tread and the road. This
hydroplaning action can cause loss of traction, braking
ability, and control.
•After going through deep water or a car wash, brakes
may become wet, resulting in decreased performance
and unpredictable braking action. Dry the brakes by
gentle, intermittent pedal action while driving at very
slow speeds.
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. 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
6
SAFETY 227
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!
The Brake Assist System (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, 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

Hill Descent Control (HDC) — If Equipped
HDC is intended for low speed off road driving while in
4WD Low Range. HDC maintains vehicle speed while
descending hills during various driving situations. HDC
controls vehicle speed by actively controlling the brakes.
HDC has three states:
1. Off (feature is not enabled and will not activate).
2. Enabled (feature is enabled and ready but activation
conditions are not met, or driver is actively overriding
with brake or throttle application).
3. Active (feature is enabled and actively controlling
vehicle speed).
Enabling HDC
HDC is enabled by pushing the HDC switch, but the
following conditions must also be met to enable HDC:
•Driveline is in 4WD Low Range.
•Vehicle speed is below 7.5 mph (12 km/h).
•Electric Park Brake (EPB) is released.
•Driver door is closed.
Hill Descent Control (Trailhawk)

SAFETY 231
Feedback To The Driver:
The instrument cluster has an HDC icon and the HDC
switch has an LED which offer feedback to the driver
about the state HDC is in.
•The cluster icon and switch lamp will illuminate and
remain solid when HDC is enabled or activated. This is
the normal operating condition for HDC.
•The cluster icon and switch lamp will flash for several
seconds then extinguish when the driver pushes the
HDC switch when enable conditions have not been met.
•The cluster icon and switch lamp will flash for several
seconds then extinguish when HDC deactivates due to
excess speed.
•The cluster icon and switch lamp will flash when HDC
deactivates due to overheated brakes. The flashing will
stop and HDC will activate again once the brakes have
cooled sufficiently.
The Hill Descent Switch is located within the Selec-
Terrain™ knob in the upper right position.
WARNING!
HDC is only intended to assist the driver in control-
ling vehicle speed when descending hills. The driver
must remain attentive to the driving conditions and
is responsible for maintaining a safe vehicle speed.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for oversteering or understeering of the vehicle by
applying the brake of the appropriate wheel to assist in
counteracting the oversteer or understeer condition. En-
gine power may also be reduced to help the vehicle
maintain the desired path.

SAFETY 233
NOTE:TSC cannot stop all trailers from swaying. Al-
ways use caution when towing a trailer and follow the
trailer tongue weight recommendations. Refer to “Trailer
Towing” in this section for further information. When
TSC is functioning, the “ESC Activation/Malfunction
Indicator 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 disabled when the ESC system is in the
“Partial Off” mode.
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and adjust the
trailer load to eliminate trailer sway.
Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time required to
reach full braking during emergency braking situations.
It anticipates when an emergency braking situation may
occur by monitoring how fast the throttle is released by
the driver. When the throttle is released very quickly,
Ready Alert Braking applies a small amount of brake
pressure. This brake pressure will not be noticed by the
driver. The brake system uses this brake pressure to allow
a fast brake response if the driver applies the brakes.
Dynamic Steering Torque (DST)
The DST function uses the integration of the ESC system
with the electric power steering to increase the safety
level of the whole car. In critical situations (understeer-
ing, oversteering, braking with different grip conditions),
through the DST function the ESC system controls the
steering to implement an additional torque contribution
