Hill-start assist control
After the engine is stopped by the Stop & Start system when the vehi-
cle is on an incline, brake force is temporarily maintained to prevent
rolling backwards until the engine is restarted and drive force is gener-
ated. When drive force is generated, the maintained brake force is
automatically canceled.
● This system operates on flat surfaces as well as steep grades.
● Sound may be generated by the brakes, but this is not a malfunc-
tion.
● The brake pedal response may change and vibration may occur,
but these are not malfunctions.
■
