Hill-start assist system
On uphill grades, the hill-start assist system
maintains the pressure in the brake system
for approximately 1 second after you have
released the brake pedal. Therefore, you can
start off smoothly without the vehicle moving
immediately after releasing the brake pedal.
GWarning!
The hill-start assist system is not designed to
function as a parking brake. It does not
prevent the vehicle from moving when parked
on an incline.
Always engage the parking brake in addition
to shifting the automatic transmission into
park position P.
