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
contrasts, the use of sunglasses, or if the
driver is not looking straight ahead may
make the visual warning signal in the wind-
screen 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 animals 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 sup-
port is activated.
Brake support reinforces the driver’s braking
action if the system considers that the braking
is not sufficient to avoid a collision.
3 - Auto Brake
The automatic brake function is activated last.
If in this situation the driver has not yet started
to take evasive action and the risk of collision
is imminent then the automatic braking func-
tion is deployed - this takes place irrespective
of whether or not the driver brakes. Braking
then takes place with full brake force in order
to reduce collision speed, or with limited brake
force if it is sufficient to avoid a collision.
The seatbelt tensioner can be activated in con-
nection with the engagement of the automatic
brake function.
In some situations, the action of Auto-brake
may begin with light braking and then pro-
gress to full brake action.
When City Safety has prevented a collision
with a stationary object, the car remains sta-
tionary in anticipation of positive action by the
driver. If the car has been braked to avoid colli-
sion with a slower vehicle in front, its speed is
reduced to match that of the vehicle in front.
NOTE
On cars with manual gearbox, the engine
stops when the Auto-brake function has
stopped the car, unless the driver has man-
aged to depress the clutch pedal before-
hand.
The driver can always interrupt a braking inter-
vention by firmly depressing the accelerator
pedal.
NOTE
When City Safety brakes, the brake lights
come on.
When City Safety is activated and brakes the
vehicle, the driver display shows a text mes-
sage to the effect that the function is/has
been active.
