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 Alert1.
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. This feature uses the rear-facing cameras to detect traffic. When it detects a moving vehicle, you will see an alert in the parking view and hear an audible alert.

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

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 cars, 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, the cameras' 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 reverse out of a parking space, the cameras' fields of view gradually increase, 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 18 km/h (11 mph).
  • If the rear-facing cameras are obstructed, such as by an attached trailer or bike rack, these alerts become unavailable.
  • Detection of traffic behind the vehicle relies on the rear-facing cameras. Be sure to read the separate section about camera detection and limitations.
