Alerts about traffic crossing behind the vehicle

When you're reversing at low speed, the vehicle can warn you if it detects traffic about to pass behind you. This feature is called Cross Traffic Alert.
Warning about crossing traffic behind vehicle.
Your vehicle can detect a vehicle crossing behind you: for example, when reversing out of a parking spot. This allows it to warn you so that you can slow down or brake.

Alerts about traffic crossing behind the vehicle are only available when the vehicle is in reverse (R) or rolling backwards in neutral (N). This feature uses the rear radar to detect traffic. When it detects a moving vehicle, an alert appears in the center display, and you will hear a sound.

This feature is primarily designed to detect larger vehicles in motion, such as cars. In favorable conditions it may also be able to warn you of smaller moving objects, such as cyclists and pedestrians.

 Important

Driver responsibility

Alerts about traffic crossing behind are a supplement to safe driving practices. They do not reduce or replace the need for the driver to stay attentive and focused on driving safely.

 Note

Automatic braking for crossing traffic

If automatic braking1 is enabled, the vehicle may also intervene by braking to prevent or mitigate an imminent collision with traffic detected behind you.

Detection zones

Cross traffic alert detection zones
The situation in this image illustrates how surrounding objects such as parked vehicles can limit the vehicle's ability to detect other vehicles and traffic situations. In a situation without obstacles, the effective detection zones are the same on both sides.

 Note

Backing out of a parking space

When parked, your rear corner radars' side views might be obstructed, which affects detection of crossing traffic. This happens when you are parked with the back corners of your vehicle further forward in the space than adjacent vehicles or other objects. This effect is particularly noticeable in angled parking spaces. However, as you back out of a parking space, the radar units gradually increase their view, making detection possible. To minimize the risk of delayed or no detection when backing out of a parking space, go slowly.

Conditions and limitations

  • The alerts are only available when reversing at speeds below 15 km/h (9 mph).
  • If the vehicle deactivates the rear radar units, this feature is automatically disabled. This happens if a trailer is connected. Towbar-mounted accessories that are not connected electrically to the vehicle does not disable the rear radar units but can obstruct them.
  • Detection of traffic behind the vehicle relies on detection by the rear radar. Be sure to read the separate section about the limitations of radar detection.
