Hill Descent Control
Hill Descent Control helps the driver
when traveling on slopes.
How it works
Hill descent control maintains the speed on all four wheels when driving forward or in reverse on steep inclines through
automatic braking interventions. The wheels will not lock up because the Anti-Lock Brake System (ABS) remains active.
When starting to drive downhill at speeds less than approx. 30 km/h (approx. 19 mph), the speed is limited to minimum
approx. 2 km/h (approx. 1 mph) and maximum approx. 30 km/h (approx. 19 mph). The driver can increase or decrease the
vehicle speed within these speed limits by accelerating or braking.
However, there must be enough traction. If the downhill slope is icy or the surface is greasy, for example, Hill Descent Control
cannot function properly.
Displays
Depending on the driving situation, one of the following indicator lights will light up in the instrument cluster:
Hill Descent Control is active.
Hill Descent Control is not active.
If hill descent control is not active, the indicator light turns gray. The system is activated, but it is not regulating.
When is it active?
Hill descent assist is automatically activated under the following conditions:
The vehicle engine must be running.
The speed must be less than approx. 30 km/h (approx. 19 mph), the
display.
indicator light appears in the instrument cluster
The gradient must be at least 10%.
The brake pedal or accelerator pedal must not be pressed.
Hill Descent Control is deactivated if the speed is higher than approx. 30 km/h (approx. 19 mph), when the brake pedal or
accelerator pedal is pressed, or the gradient is less than 5%.
WARNING
Hill Descent Control is not a replacement for the driver's attention and works only within the system limitations. Hill
Descent Control cannot detect all driving situations and may not react, or may react with a delay, or may react in a way
that is not desired. If you are careless, there is a risk of accidents due to unintentional vehicle movement. This can cause
serious or fatal injuries.
Always stay attentive and do not rely solely on the system. The driver is always responsible for control of the
vehicle.
Be aware that Hill Descent Control cannot hold the vehicle on the incline or brake sufficiently going downhill in
every situation, for example if the ground is slippery or icy.
Always be ready to brake, in particular if the ground is slippery or icy.
Manually brake the vehicle if the vehicle moves faster despite Hill Descent Control.
Always adapt your speed and driving style to the visibility, weather, road and traffic conditions.
