Collision Warning
The radar sensor and the camera work
together to detect a pedestrian, a cyclist, sta-
tionary vehicles and vehicles that are moving
in the same direction as your vehicle. If there
is a risk of collision with a vehicle, a cyclist or
a pedestrian, the driver is alerted by a flash-
ing red warning light and an audible warning
signal. The system 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, pedestrian or a cyclist,
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.
