The downhill assist control system helps to prevent excessive speed on steep downhill slopes.
The system will operate when the vehicle is traveling under 15 mph (25 km/h) with the accelerator and brake pedals released.

The downhill assist control system indicator will come on and the system will operate. When the system is in operation, the slip indicator light will flash, and the stop lights/high mounted stop lights will be lit. A sound may also occur during the operation. This does not indicate a malfunction.
