Collision warnings and mitigation

Your vehicle has warning features designed to reduce the risk of a collision. If a collision cannot be avoided, early warning and response can help reduce its effects.
Collision warning features include:
  • Forward collision warnings
  • Warnings about vehicles cutting across your lane
  • Rear collision warnings

 Note

Safety interventions

If a sufficiently urgent risk of collision is identified, the vehicle can intervene to avoid or mitigate the collision without any preceding collision warnings. In this case, the warnings will be shown at the same time as the intervention.

 Warning

Never rely on collision warnings or safety interventions by the vehicle as a replacement for safe driving practices. Drive the vehicle with the same attention to safety as you would need to in a vehicle without these features.

Forward collision warnings

Forward collision warnings can occur if you are getting too close to a vehicle in front of you. The vehicle warns you if it identifies a collision risk that requires your immediate attention.

The situation and level of urgency affect how forward collision warnings are communicated. Warnings can be communicated visually in the instrument panel, with sound and with seat belt and brake pulses.

Warnings about vehicles cutting across your lane

Your vehicle can warn you if you are about to be cut off, such as when a vehicle changes lanes just in front of you. Vehicles that swerve or move unpredictably in adjacent lanes can trigger these warnings as well. Your vehicle uses messages in the instrument panel to warn you in these situations.

Rear collision warnings

If your vehicle identifies a situation with a high risk of a rear collision, it can flash its rear lights to warn drivers behind you. Rear collision warnings appear automatically if you slow down suddenly1, such as during very hard braking. Warnings can also be provided if your vehicle detects a vehicle rapidly approaching from behind. In this case, you do not need to be slowing down for a warning to appear. Warnings can appear both when you're driving and when stopped, but only if your vehicle detects a sufficiently high risk of collision.

When you are in situations that cause rear collision warnings, your vehicle can pretension your seat belt as a safety measure. If your vehicle is at a standstill, it also applies hard braking as a precaution in case there is an unavoidable rear collision.

 Note

Collision response

If a collision cannot be avoided, the vehicle can respond in other ways to protect occupants and reduce the danger to surrounding traffic. Read more about these features in the safety section of this manual.
