Volvo XC90: Starting and driving / Braking assist after a collision

In a collision in which the activation level is reached for the pyrotechnic seat belt tensioners or airbags, or if a collision with a large animal is detected, the vehicle's brakes will be automatically activated. This function is intended to help prevent or reduce the effects of any subsequent collision.

After a serious collision, it may no longer be possible to control and steer the vehicle. In order to avoid or mitigate a possible further collision with a vehicle or an object in the vehicle's path, the brake assist system is activated automatically to help stop the vehicle safely.

If braking is not appropriate, e.g. if there is a risk of being hit by passing traffic, the driver can override the system by depressing the accelerator pedal.

This function assumes that the brake system is intact after a collision.
