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
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 or Full Off mode. Refer to “Elec-
tronic 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 his foot off 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 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.
