WARNING
•
Collision Warning will not provide a
warning or brake the vehicle for
pedestrians in darkness or in tunnels,
even if there is street lighting in the
area.
•
The auto-brake function can help pre-
vent a collision or reduce the speed at
impact but the driver should always
apply the brakes for the best possible
braking effect, even if auto-brake is
actively applying the brakes.
•
Never wait for a collision warning. This
system is designed to be a supple-
mentary driving aid. It is not, however,
intended to replace the driver's atten-
tion and judgement. The driver is
responsible for maintaining a safe dis-
tance and speed, even when the colli-
sion warning system is in use.
•
Maintenance of the Collision Warning
system's components must only be
performed by a trained and qualified
Volvo technician.

Collision Warning
The radar sensor and the camera work
together to detect a pedestrian, stationary
vehicles and vehicles that are moving in the
same direction as your vehicle. If there is a
risk of collision with a vehicle or a pedestrian,
the driver is alerted by a flashing red warning
light and an audible warning signal. Collision
warning is active at speeds above 3 mph
(4 km/h).
Brake Support
If the risk of collision continues to increase
after the collision warning has been given,
Brake Support is activated. Brake Support
prepares the brake system to react quickly,
and the brakes are applied slightly. This may
be experienced as a light tug.
If the brakes are applied quickly, full braking
effect will be provided. Brake Support also
increases brake force if the system deter-
mines that the driver has not applied ade-
quate pressure on the brake pedal.
Auto-brake
If a collision is imminent and the driver has
not applied the brakes or begun to steer
around the vehicle or pedestrian, the auto-
brake function is activated without the driver
pressing the brake pedal. Full brake force is
applied to help reduce the vehicle’s speed
when the collision occurs or limited brake
force is applied if this is sufficient to avoid the
collision.
NOTE
The auto-brake and brake support func-
tions are always on and cannot be turned
off.
