Brake Assist

If equipped, Brake Assist is
designed to assist in stopping or
decreasing vehicle speed in
emergency driving conditions. This
feature uses the stability system
hydraulic brake control module to
supplement the power brake system
under conditions where the driver
has quickly and forcefully applied
the brake pedal in an attempt to
quickly stop or slow down the
vehicle. The stability system
hydraulic brake control module
increases brake pressure at each
corner of the vehicle until the ABS
activates. Minor brake pedal
pulsation or pedal movement during
this time is normal and the driver
should continue to apply the brake
pedal as the driving situation
dictates. The brake assist feature
will automatically disengage when
Driving and Operating
the brake pedal is released or brake
pedal pressure is quickly
decreased.

Hill Start Assist (HSA)

If equipped, Hill Start Assist (HSA)
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 to ensure that there is no
rolling. The brakes will automatically
release when the accelerator pedal
is applied within the two-second
window. 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).
