Brake Assist

This vehicle has a brake assist feature
designed to assist the driver 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

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 the
brake pedal is released or brake pedal
pressure is quickly decreased.

Hill Start Assist (HSA)

Hill Start Assist (HSA) may
automatically activate when the

enabled. This feature is designed to
prevent the vehicle from rolling, either
forward or rearward, during vehicle
drive off. During the transition from
releasing the brake pedal to
accelerating to drive off on a hill, HSA
holds the braking pressure to prevent
rolling. HSA will not activate if the
DRIVING AND OPERATING
vehicle is in a drive gear and facing
downhill or if the vehicle is facing
uphill and in R (Reverse).
