Collision warnings and mitigation

Updated 28/10/2024

Your car 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 an urgent enough collision risk is identified, the car can intervene to avoid or mitigate the collision without any preceding collision warnings. The warnings will then instead be shown simultaneously to the intervention.

Warning

Never rely on collision warnings or safety interventions by the car to be a replacement for safe driving practices. Drive the car with the same attention to safety as required by a car 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 car 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 head-up display, with sound and brake pulses.

Your car can also provide you with distance warnings in the head-up display to help you maintain a safe distance to vehicles ahead.

Warnings about vehicles cutting across your lane

Your car 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 car uses messages in the driver display to warn you in these situations.

Rear collision warnings

If your car 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 car detects a vehicle rapidly approaching from behind. In this case, you do not need to be slowing down for a warning to appear. They can appear both when you're driving and when stopped, but only if your car detects a high enough risk of collision.

When you are in situations that cause rear collision warnings, your car can pretension your belt as a safety measure. If your car 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 car 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.
