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.
The function for assisting when starting the vehicle on inclines (HSA1)
helps prevent the vehicle from rolling backward when starting on an uphill gradient...
The vehicle recovers kinetic energy during braking in order to reduce fuel
consumption and emissions.

Other information:
All-wheel drive (AWD1), also called fourwheel drive, means that power
is distributed to all four wheels, which improves traction.
To achieve the best traction, power is automatically directed to the wheels that
have the best grip. The system continuously calculates the need for torque to the
rear wheels, and can immediately redistribute up to half of the engine's torque
to the rear wheels...
