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.

Detail
The brake lights automatically come on while the system is in operation.

The system may not operate when driving down a gentle slope. Check the Hill Descent Control System indicator to see if the system is in operation.

The system may activate even when not driving downhill, such as when the vehicle leans while driving over uneven surfaces.

Hill Descent Control Operating Conditions

The system operates under the following conditions.

  • Driving at a speed between about 2-12 mph (3-20 km/h).
  • Driving downhill.
  • Accelerator pedal and brake pedal are not depressed.

How to Operate Hill Descent Control

To turn the system on

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

  • The system goes into standby mode, and the Hill Descent Control System indicator (white) comes on.

When all the working conditions are met, the system activates, and the vehicle begins to maintain the vehicle speed when driving downhill.

  • The Hill Descent Control System indicator (green) comes on when operating.

To adjust the set speed

Depress the accelerator pedal or brake pedal to adjust the vehicle speed within the operating range. The vehicle speed at which you release the accelerator pedal or brake pedal will be the set speed.

To turn the system off

Press the button to turn the system off.

Detail
When the vehicle speed is 37 mph (60 km/h) or more, the system turns off automatically.
Detail
Using the system repeatedly for a long time may cause the brakes to heat up and make the system go into standby mode temporarily.

Hill Descent Control is turned off every time you turn the engine off, even if it was turned on the last time you drove the vehicle.

The pedals may vibrate or you may hear the system working when in operation.
