Interventions and warnings when reversing

Your vehicle has specialized features that can intervene and help prevent collisions when you are reversing at low speeds, such as when parking.

Forms of detection

The vehicle has several ways to identify objects that are in or approaching your reversing path. If it detects an object, the vehicle can provide warnings or intervene by braking.

Ultrasonic parking sensorsThese sensors can identify certain obstacles immediately behind the vehicle when reversing at low speeds.
Rear-facing radarThe vehicle's rear radar can detect traffic approaching your reversing path from the sides.
CameraCertain features may use camera detection to help identify obstacles when reversing.

 Important

These types of detection have limitations and cannot detect all obstacles in every situation. Be sure to read the separate manual sections about their conditions and limitations.

When you are reversing, some information from the detection systems can be communicated in the parking view.

Warning and intervention features

Warning about crossing traffic behind vehicle.
The following features are designed to react when the vehicle identifies a risk of collision when reversing.
Alerts about traffic crossing behind the vehicle1Your vehicle can provide visual and audible alerts if it detects traffic about to cross your reversing path.
Automatic braking when reversing2The vehicle can automatically brake to prevent a collision when reversing. This can happen if it detects an obstacle or crossing traffic behind the vehicle.

 Tip

Temporary deactivation

The rear auto brake can be temporarily turned off if the interventions are too frequent or distracting. For example, reversing in tall grass or maneuvering in very tight spaces can cause unwanted braking interventions.

 Important

Use responsibly

Warnings and interventions when reversing 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.

Pay attention to surroundings

The driver is always responsible for paying attention to the vehicle's surroundings and ensuring that it is safe to maneuver the vehicle.

Detection conditions

If the vehicle deactivates the rear radars, the cross traffic alert and rear auto brake features are 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 or obstacles behind the vehicle relies on detection by the rear radars. Be sure to read the separate section about the limitations of radar detection.

Conditions for automatic braking

When and how your vehicle performs braking interventions during low-speed reversing depends on whether the detected obstacle is stationary or not.
  • If the detected obstacle is moving, such as traffic about to cross your reversing path, automatic braking is available and may intervene when you are reversing at speeds below 15 km/h (9 mph).
  • If the detected obstacle is stationary, automatic braking interventions only occur when you are reversing at speeds between 2 km/h (1 mph) and 15 km/h (9 mph). This is to avoid unwanted braking interventions during low-speed maneuvering in tight spaces.
