Warning Levels and Braking Intervention
Speed ranges
Front Assist provides maximum assistance in the following speed ranges:
Reaction to vehicles: around 5\mathrm{km / h} to around 160\mathrm{km / h} Reaction to bicycles and motorcycles: around 5\mathrm{km / h} to around 160\mathrm{km / h} Reaction to pedestrians: around 5\mathrm{km / h} to around 85~\mathrm{km / h}
The assistance may include an advance warning, an urgent warning and automatic braking or a braking intervention. A distance warning may also be displayed.
Influencing factors
Whether and in what speed range Front Assist reacts to the specified objects depends on the following factors:
Type of object. Direction of travel of the object. Speed of the object. Speed of the vehicle.
The operating range may therefore be restricted if the vehicle approaches an object very quickly and there is therefore little time for a reaction.
In addition, not all warning levels are used in all situations. Depending on speed, there may not be an advance warning or an urgent warning, for example. Instead, automatic braking may take place immediately in order to ensure optimum protection for the object.
Distance warning
Front Assist detects when safety is endangered by driving too close to the vehicle in front.
The indicator lamp lights up. Increase the distance.
Advance warning
Front Assist detects a possible collision and prepares the vehicle for possible emergency braking.
An acoustic warning sounds and the red warning lamp lights up. Brake or take avoiding action.
Urgent warning
If you do not react to the advance warning, the system may initiate a short braking jolt in order to draw attention to the increasing collision risk. Brake or take avoiding action.
Automatic braking
Front Assist can brake the vehicle automatically in several stages with increasing braking force. The reduced speed means that it is possible to minimize the consequences of an accident.
Braking intervention
If the system detects that you are braking insufficiently when there is a risk of collision, Front Assist can increase the braking force and help prevent a collision. The braking intervention takes place only for as long as you press the brake pedal hard.
