Driving and Operating

taking off on a hill. When no
roll back is desired, an applied
EPB will allow both feet to be
used for the clutch and
accelerator pedals in
preparation for starting the
vehicle moving in the intended
direction. In this case, there is
no need to press the switch to
release the EPB.
Brake Assist
Brake Assist detects rapid
brake pedal applications due
to emergency braking
situations and provides
additional braking to activate
the Antilock Brake System
(ABS) if the brake pedal is not
pushed hard enough to
activate ABS normally. Minor
noise, brake pedal pulsation,
and/or pedal movement during
this time may occur. Continue
to apply the brake pedal as
the driving situation dictates.
Brake Assist disengages when
the brake pedal is released.
Hill Start Assist (HSA)
{
Warning
Do not rely on the HSA
feature. HSA does not
replace the need to pay
attention and drive safely.
You may not hear or feel
alerts or warnings provided
by this system. Failure to
use proper care when
driving may result in injury,
death, or vehicle damage.
See Defensive Driving
When the vehicle is stopped
on a grade, Hill Start Assist
(HSA) temporarily prevents
the vehicle from rolling in an
unintended direction during
the transition from brake
pedal release to accelerator
pedal apply. The brakes
release when the accelerator
pedal is applied or
automatically release after a
few seconds. The brakes may
also release under other
conditions. Do not rely on HSA
to hold the vehicle.
HSA is available when the
vehicle is facing uphill in a
forward gear, or when facing
downhill in R (Reverse). The
vehicle must come to a
complete stop on a grade for
HSA to activate.
