ELECTRONIC BRAKE CONTROL SYSTEM

Your vehicle is equipped with a advanced electronic
brake control system that includes Anti-Lock Brake Sys-
tem (ABS), Brake Assist System (BAS), Traction Control
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.

Anti-Lock Brake System (ABS)

This system aids the driver in maintaining vehicle control
under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lockup and
help avoid skidding on slippery surfaces during braking.
Refer to “Anti-Lock Brake System” in “Starting and
Operating” 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
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 prevail-
ing road conditions.

WARNING! (Continued)

The BAS cannot prevent collisions, including

those resulting from excessive speed in turns,
driving on very slippery surfaces, or hydroplan-
ing.

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)

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 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. Refer to “Electronic Stability
Control (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 their foot off of the
brake pedal. If the driver does not apply the throttle
during this short period of time, the system will release
brake pressure and the vehicle will roll down the hill. The
system will release brake pressure in proportion to
amount of throttle applied as the vehicle starts to move in
the intended direction of travel.
