Hill Start Assist
Hill Start Assist (HSA) helps prevent the vehicle
from rolling backwards when starting up a hill. If
you are backing up a hill, HSA helps prevent the
vehicle from rolling forward.
HSA makes it easier to start or back up on a hill
by retaining pressure on the brake pedal for sev-
eral seconds after the pedal has been released in
order to keep the vehicle at a standstill.
The brakes will be released after several seconds
or when the driver presses the accelerator pedal.
HSA is available even if the Auto-hold braking
function is turned off.
