When the parking brake is applied with the ignition
switch in the ON position, the “Brake Warning Light” in
the instrument cluster will illuminate.NOTE:
•
When the parking brake is applied and the automatic
transmission is placed in gear, the “Brake Warning
Light” will flash. If vehicle speed is detected, a chime
will sound to alert the driver. Fully release the parking
brake before attempting to move the vehicle.
• This light only shows that the parking brake is ap-
plied. It does not show the degree of brake application.
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. For vehicles equipped
with an automatic transmission, apply the parking brake
before placing the shift lever in PARK, otherwise the load
on the transmission locking mechanism 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.
Parking Brake
242 STARTING AND OPERATING

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 func-
tion. However, there will be some loss of overall braking
effectiveness. You may notice increased pedal travel
during application, greater pedal force required to slow
or stop, and potential activation of the “Brake System
Warning Light”.
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.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with a advanced electronic
brake control system that includes the Anti-Lock Brake
System (ABS), Brake Assist System (BAS), Traction Con-
trol System (TCS), Hill Start Assist (HSA), and Electronic
Stability Control (ESC). All systems work together to
enhance vehicle stability and control in various driving
conditions and are commonly referred to as ESC.
Four-Wheel Anti-Lock Brake System (ABS)
The Four-Wheel ABS is designed to aid the driver in
maintaining vehicle control under adverse braking con-
ditions. The system operates with a separate computer to
modulate hydraulic pressure, to prevent wheel lock-up
and to help avoid skidding on slippery surfaces.
The system’s pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation, which is
normal.
244 STARTING AND OPERATING

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
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 applycontinuousbrak-
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 prevail-
ing road conditions.
• The BAS cannot prevent collisions, including those
resulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning.
• 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.
Traction Control System (TCS)
The Traction Control System (TCS) monitors the amount
of wheel spin of each of the driven wheels. If wheel spin
is detected, brake pressure is applied to the slipping
246 STARTING AND OPERATING

wheel(s) and engine power is reduced to provide en-
hanced acceleration and stability. A feature of the TCS
system, Brake Limited Differential (BLD), functions simi-
lar 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. Refer to “Electronic Stability Con-
trol (ESC)” in this section for further information.
Hill Start Assist (HSA)
The HSA system is designed to assist the driver when
starting a vehicle from a stop on a hill. HSA will maintain
the level of brake pressure the driver applied for a short
period of time after the driver takes his foot off the brake
pedal. If the driver does not apply the throttle during this
short period of time, the system will release brakepressure and the vehicle will roll down the hill. The
system will release brake pressure in proportion to the
amount of throttle applied as the vehicle starts to move in
the intended direction of travel.
HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
•
Vehicle must be stopped.
• Vehicle must be on a 5% grade or greater hill.
• Gear selection matches vehicle uphill direction (i.e.,
vehicle in NEUTRAL (manual transmission), vehicle
facing uphill is in forward gear; vehicle backing uphill
is in REVERSE gear).

STARTING AND OPERATING 247

WARNING!
There may be situations on minor hills with a loaded
vehicle, or while pulling a trailer, when the system
will not activate and slight rolling may occur. This
could cause a collision with another vehicle or object.
Always remember the driver is responsible for brak-
ing the vehicle.
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 oversteering or understeering condi-
tion. Engine power may also be reduced to help the
vehicle maintain the desired path. ESC uses sensors in
the vehicle to determine the vehicle path intended by the
driver and compares it to the actual path of the vehicle.When the actual path does not match the intended path,
ESC applies the brake of the appropriate wheel to assist
in counteracting the oversteer or understeer condition.
•
Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
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 cannot prevent all
accidents, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent collisions

WARNING!(Continued)
resulting from loss of vehicle control due to inap-
propriate driver input for the conditions. Only a
safe, attentive, and skillful driver can prevent acci-
dents. 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.
• Vehicle modifications, or failure to properly main-
tain your vehicle, may change the handling charac-
teristics of your vehicle, and may negatively affect
the performance of the ESC system. Changes to the
steering system, suspension, braking system, tire
type and size or wheel size may adversely affect
ESC performance. Improperly inflated and un-
evenly worn tires may also degrade ESC perfor-
mance. Any vehicle modification or poor vehicle

WARNING! (Continued)
maintenance that reduces the effectiveness of the
ESC system can increase the risk of loss of vehicle
control, vehicle rollover, personal injury and death.
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 switch is turned to the MAR
(ON/RUN) position for four seconds. 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
5
STARTING AND OPERATING 249

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 pushing the “ESC
OFF” button. Once the situation requiring “Partial Off”
mode is overcome, turn ESC back on by momentarily
pushing the “ESC OFF” button. This may be done while
the vehicle is in motion.
WARNING!
When in “Partial Off” mode, the TCS functionality of
ESC (except for the limited slip feature described in
the TCS section) has been disabled and the “ESC Off
Indicator Light” will be illuminated. When in “Par-
tial Off” mode, the engine power reduction of TCS is
disabled, and the enhanced vehicle stability offered
by the ESC system is reduced.
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 roadway, or striking objects or
other vehicles.
252 STARTING AND OPERATING

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.
