Hill descent assist brakes all four wheels automatically in order to limit speed when driving either forward or reverse on hills with a grade up to approximately 50%.
When the hill descent assist is on, the current driving speed, when your vehicle entered the incline is maintained. It is only possible to switch on the assist when driving slower than 37 mph (60 km/h). The assist works between approximately 2 and 19 mph (4 and 30 km/h). The driver can increase or decrease the vehicle speed within these limits by depressing the accelerator or brake pedal In addition, vehicle steerability is increased due to the braking distribution when driving in reverse.
There must be however sufficient ground adhesion.
The hill descent assist can not do its job if the incline is icy or if the incline ground is loose.
The system does not work at speeds between 19 and 37 mph (30 and 60 km/h). The system is then in the ready-mode. The diode in the button will come on. The system automatically switched off when you drive faster than 37 mph (60 km/h). The diode will go out in this case.
Active control at a specific speed up to approximately 19 mph (30 km/h) will appear in the instrument cluster display > fig. 188. Two dashes "--" will appear in the ready mode.
Hill descent assist is automatically activated under the following conditions:
- the diode in the button illuminates,
- vehicle speed is below approximately 19 mph (30 km/h)
- the incline is 10%.
WARNING
- Always adapt your speed to the weather, road and traffic conditions. Do not let the increased safety provided tempt you into taking risks.
- The hill descent assist system cannot overcome the laws of physics. Your driving style must always be adapted to the current road and traffic conditions.
- The hill descent assist may not be able to hold your vehicle at a constant speed under all conditions while driving on an incline (for example if ground under the vehicle is loose).
