Collision prevention assist

General notes

COLLISION PREVENTION ASSIST includes the distance alert function and the Adaptive Emergency Brake Assist function, described in the following sections.

Distance alert

The distance alert is not always able to detect objects or accurately analyze complex situations.

In this case, the distance alert may

• issue a warning in error
• fail to warn you

There is a risk of an accident. Always pay attention to traffic conditions and be ready to brake, especially when the distance alert warns you.

The distance alert does not take into account

• persons and animals
• vehicles travelling in the opposite direction
• vehicles crossing on cross traffic routes
• curves

As a result, the distance alert cannot always warn you in critical situations. There is a risk of an accident. Always pay attention to traffic conditions and be ready to brake.

• Activation and deactivation: activate and deactivate the distance alert via the on-board computer.

When the distance alert is activated, the symbolappears in the multifunction display, provided the HOLD function is not activated. On vehicles equipped with Active Parking Assist, the symbolappears if the transmission is in P or if you are driving faster than 35 km/h .

The distance alert helps you reduce the risk of colliding with the vehicle ahead or reduce the consequences of a possible collision. If the distance alert detects a risk of collision, you are warned by a visual and audible signal. Without your intervention, the distance alert cannot prevent a collision.

The distance alert warns you from approx. 30 km/h when

• for several seconds, the distance to the vehicle ahead is too short for your current speed. The distance alert warning lampin the instrument cluster then lights up.
• you are approaching the vehicle ahead very rapidly. In this case, an intermittent warning signal sounds and the distance alert warning lampin the instrument cluster lights up.

• Brake immediately to increase the distance to the vehicle ahead.
• Steer around the obstacle, if you can do so safely.

For the distance alert to work, the function must be activated in the on-board computer and be operational.

In complex traffic situations, the system may issue warnings in error due to its design.

The distance alert uses the radar sensor system to detect obstacles that have been in your path for a certain time.

The distance alert can also react to stationary obstacles (such as stopped or parked vehicles) up to a speed of approx. 70 km/h.

If you approach an obstacle and the distance alert detects a risk of collision, it warns you with a visual and audible signal.

Detection may be limited in particular

• when the sensors are dirty or covered
• in snowfall or heavy rain
• when interference is caused by other radar sources
• in the case of strong radar reflection, for example in underground car parks
• if the vehicle ahead is narrow, for example a motorcycle
• if the vehicle ahead is driving on a path offset from the center of your vehicle

If the front of the vehicle has been damaged, have the adjustment and function of the radar sensors checked by a qualified workshop.

This also applies to low-speed collisions that do not cause any visible damage to the front of the vehicle.
