Hill Start Assist (HSA)

Non‐hybrid vehicles with StabiliTrak

have a Hill Start Assist (HSA)

feature, which may be useful when

the vehicle is stopped on a grade.

This feature is designed to prevent

the vehicle from rolling, either

forward or rearward, during vehicle

drive off. After the driver completely

stops and holds the vehicle in a

complete standstill on a grade, HSA

will be automatically activated.

During the transition period between

when the driver releases the brake

pedal and starts to accelerate to

drive off on a grade, HSA holds the

braking pressure for a maximum of

two seconds to ensure that there is

no rolling. The brakes will

automatically release when the

accelerator pedal is applied within

the two‐second window. If the

vehicle is equipped with the

Integrated Trailer Brake Control

(ITBC) system, HSA may also apply

the trailer brakes. It will not activate

if the vehicle is in a drive gear and

facing downhill or if the vehicle is

facing uphill and in R (Reverse).

There may be situations on minor

hills (less than 5% grade) with a

loaded vehicle or while pulling a

trailer where HSA will not activate.

Ride Control Systems

StabiliTrak

®

System

The vehicle has a vehicle stability

enhancement system called

StabiliTrak. It is an advanced

computer-controlled system that

assists the driver with directional

control of the vehicle in difficult

driving conditions.

StabiliTrak activates when the

computer senses a discrepancy

between the intended path and the

direction the vehicle is actually

traveling. StabiliTrak selectively

applies braking pressure at any one

of the vehicle's brakes to assist the

driver with keeping the vehicle on

the intended path.
