Alerts about traffic crossing behind the car

When you're reversing at low speed, the car can warn you if it detects traffic about to pass behind you. The name of this feature is Cross Traffic Alert1.
Your car can detect a car 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 car are only available when the car is in reverse. This feature uses the rear-facing cameras to detect traffic. When it detects a moving vehicle, an alert appears in the parking view along with a sound.

This feature is primarily designed for detecting larger vehicles in motion, such as cars. In favourable 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

The car 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 shown in this image illustrates how surrounding objects, such as parked cars can limit the car'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

Reversing out of a parking space

When parked, your cameras' side views might be obstructed, which affects detection of crossing traffic. This happens when you are parked with the rear corners of your car further in than adjacent cars or other objects. This effect is particularly noticeable in angled parking spaces. However, as you reverse out of a parking space, the cameras' views gradually increase, making detection possible. To minimise the risk of late or no detection when reversing 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 car relies on the rear-facing cameras. Be sure to read the separate section about camera detection and limitations.
