● Do not overly rely on hill-start assist control. Hill-start assist control may not oper-
ate effectively on steep inclines and roads covered with ice.
● Unlike the parking brake, hill-start assist control is not intended to hold the vehi-

assist control to hold the vehicle on an incline, as doing so may lead to an acci-
dent.
