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

ESC system is in the “Partial Off” mode. Refer to “Elec-

tronic 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

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 BAS cannot prevent the natural laws of phys-

ics from acting on the vehicle, nor can it increase
the traction afforded by prevailing 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.
