Hill start assist system
WARNING
|
When the vehicle is stopped on a hill, the hill start assist system automatically keeps the brakes applied.
This helps prevent the vehicle from rolling backward in the time it takes the driver to release the brake pedal and apply the accelerator.
Hill start assist will operate automatically under the following conditions:
The maximum holding time is two seconds. After two seconds the vehicle will begin to roll back and hill start assist will stop operating completely.
Hill start assist will not operate when the shift lever is shifted into N (Neutral) or P (Park) or on a flat and level road.
