Audio-visual warning signal in the event of a

City Safety carries out three steps in the follow-
ing order:
1. Collision warning
2. Brake support
3. Auto Brake
The following text explains what happens during
the three steps:
1 - Collision warning
The driver is first warned of a potentially immi-
nent collision.
In cars equipped with a head up display
*
, the
warning is shown on the windscreen by a flashing
symbol.
Symbol for collision warning on the windscreen.
NOTE
Strong sunlight, reflections, extreme light con-
trasts, the use of sunglasses, or if the driver is
not looking straight ahead may make the vis-
ual warning signal in the windscreen difficult
to recognise.
City Safety can detect pedestrians, cyclists or
vehicles that are stationary or moving in the same
direction as the car and are ahead. City Safety
can also detect pedestrians, cyclists or large ani-
mals that are crossing the road in front of the car.
In the event of a risk of collision with a pedes-
trian, larger animal, cyclist or vehicle/vehicles the
driver's attention is alerted by means of a visual,
acoustic and brake pulse warning. There is no
brake pulse warning at lower speeds, sudden
driver braking or acceleration. The brake pulse
frequency varies according to the car's speed.
2 - Brake support
If the risk of collision has increased further after
the collision warning then the brake support is
activated.
Brake support reinforces the driver’s braking
action if the system considers that the braking is
not sufficient to avoid a collision.
