DRIVER SUPPORT
278
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.
WARNING
City Safety must not be used by the driver
to change his/her driving style - the driver
must not rely on City Safety alone and
allow it to do the braking.
