road surfaces, even if the TRC/VSC sys-
tem is operating.
Drive the vehicle carefully in conditions
where stability and power may be lost.
■

ing Assist. Active Cornering Assist
may not operate effectively when
accelerating down slopes or driving on
slippery road surfaces.
●

to ensure proper operation of the
brakes, TRC and VSC.

inclines and roads covered with ice.
● Unlike the parking brake, hill-start
assist control is not intended to hold

period of time. Do not attempt to use
hill-start assist control to hold the vehi-
cle on an incline, as doing so may lead
to an accident.
