Radar detection and limitations
Your car has a forward facing radar collecting information about the car's surroundings. This information is primarily used by driver support features in the car. Radio waves are continuously sent out and bounce back if they encounter an object in their path. As the waves return, the car can calculate things such as position and motion of the object.
Radar detection is unaffected by the light conditions, working equally well on a sunny day as in complete darkness.
Important
Use responsibly
The radar and features that rely on it are supplements to safe driving practices. They do not reduce or replace the need for the driver to stay attentive and focused on driving safely.
Detection zone and field of view
The radar's detection zone is limited by the radar's field of view and range.
- If the radar is blocked, certain features may become less effective or respond incorrectly.
- If the car detects that the radar is blocked, it may disable certain features.
- Do not place or mount anything in front of or close to the car's radar. This includes stickers, car body foil and adhesive tape.
- Paintwork damage in front of the radar can affect its performance. Contact a service point for repairs if there is any damage close to the radar.1
- Make sure that any mounted accessories, extra equipment or externally-stowed cargo don't block the car's radar.
- The radar is sensitive to buildups of dirt, ice or snow in front of it. This affects the radio waves and can reduce the radar's ability to detect objects. Radar obstruction cannot always be identified by the car. In situations where it is detected, the car communicates this via notifications in the driver display. However, it is still recommended to regularly inspect the radar and make sure the area around it is clean and free of obstructions.
Warning
Clean regularly
Camera, sensor and radar locations on the car must be cleaned on a regular basis and kept free from labels, objects, dirt and other kinds of potential obstructions. Otherwise, car functions may respond incorrectly or become less responsive or deactivated.
Other conditions and limitations
Other radar sources can cause interference and reduce the effectiveness of your car's radar.
