Hill Descent Control System

When driving down hills where engine braking is not enough to decelerate the vehicle, this system helps maintain a constant vehicle speed without needing to depress the brake pedal.

WARNING

Hill descent control cannot maintain a constant vehicle speed in every situation.

When driving down a very steep hill or on slippery road surfaces, the vehicle may not be able to maintain the vehicle speed and could cause a crash, resulting in serious injury or death.

Since Hill Descent Control is not designed to increase the limits of vehicle performance, the driver must always be aware of road surface conditions and drive safely.

Operating Conditions

The system operates under the following conditions.

  1. Driving at a speed between about 2-12 mph (3-20 km/h).
  2. Driving downhill.
  3. Accelerator pedal and brake pedal are not depressed.
    1. The brake lights automatically come on while the system is in operation.
    2. The system may not operate when driving down a gentle slope.
    3. The system may activate even when not driving downhill, such as when the vehicle leans while driving over uneven surfaces.

How to Activate the System

When the vehicle speed is less than about 12 mph (20 km/h), press thebutton () to turn the system on.
