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.
WARNING
â– When using downhill assist control system
Do not rely overmuch on the downhill assist control system.
This function does not extend the vehicle's performance limitations.
Always thoroughly check the road conditions, and drive safely.
System operation
Press the "DAC" switch
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.

Turning off the system
Press the "DAC" switch while the system is in operation.
The downhill assist control system indicator will flash as the system gradually ceases operation, and will turn off when the system is fully off.
Press the "DAC" switch while the downhill assist control system indicator is flashing to start the system again.
