Driver assist systems
NOTE: The Forward Collision Warning (FCW) cannot be switched off.
The AEBS/ACC sensor monitors the speed, the distance to and position of the objects
in front of the vehicle.
See section 'AEBS/ACC sensor' in chapter 'Driver assist systems'.
AEBS can help to minimise the risk of a collision with a vehicle in front or a stationary
vehicle or object. As a result, the effects of an accident can be mitigated. AEBS can
also recognise stationary objects and react to them, for example, by issuing a warning
and braking.
If you fail to adapt your driving style or if you are inattentive, AEBS can neither reduce
the risk of accident nor override the laws of physics. AEBS cannot take road and
weather conditions into account, nor the prevailing traffic situation. AEBS is only an aid.
You are responsible for keeping a safe distance to the vehicle in front, for the vehicle
speed, braking on time and keeping the driving lane. You should always adapt your
driving style to suit prevailing road and weather conditions.
NOTE: AEBS does not react to objects moving away from the vehicle
(overtaking vehicles, for example). This is because the distance between
them is increasing rather than decreasing.
NOTE: AEBS cannot always detect other road users (for example,
motorcycles or low bed semi-trailers) and complex traffic situations (for
example, curves, tunnels or busy city traffic).
See 'Traffic situations' in section 'AEBS/ACC sensor' in chapter 'Detection
devices'.
The AEBS system has three levels of assistance:
– Forward Collision Warning (FCW)
The system warns the driver with a red information pop-up on the instrument panel
and an acoustic signal. This to attract the driver's attention toward the traffic.
– Haptic Collision Warning (HCW)
In addition to the FCW, the AEBS system also performs a small and short braking
action to get the driver's attention.
– Emergency Braking (EB)
The system warns the driver at first, then starts braking to try to avoid, or reduce the
impact of a collision.
For further details see section 'Detection and intervention'.
AEBS Sensitivity
From a driver's perspective unjustified warnings (FCW & HCW) can occur because the
AEBS system cannot 100% correctly judge every traffic situation.
