Active City Brake - PEUGEOT 2008 Handbook

Driving
As a safety measure, the driver must carry
out these operations when stationary.
Selection
To select a memorised speed:
F Press and hold the "+" or "-" button; the
system stops at the nearest memorised
speed.
F Press and hold the "+" or "-" button again to
select another memorised speed.
A reminder of the speed and the state of the
system (on/off) is displayed in the instrument
panel.

Active City Brake

Active City Brake is a driving assistance system
that aims to avoid a frontal collision or reduce
the speed of an impact if the driver does not
react or does not react sufficiently (inadequate
brake application).
112
This system has been designed to
improve driving safety.
The driver must always check the traffic
and assess the relative distance and
speed of other vehicles.
Active City Brake cannot in any
circumstances replace the need for
vigilance on the part of the driver.
Never look at the laser sensor through
an optical instrument (magnifying glass,
microscope, etc.) at a distance of less
than 10 centimetres: risk of eye injury!
Principle
Using a laser sensor located at the top of the
windscreen, this system detects a vehicle
running in the same direction or stopped ahead
of your vehicle.
If necessary, the vehicle's braking system is
operated automatically to avoid a collision with
the vehicle ahead.
Automatic braking occurs later than if
done by the driver, so as to intervene only
when there is a high risk of collision.
Conditions of activation
Active City Brake functions if the following
conditions are met:
- the ignition is on,
- the vehicle is moving forward,
- the speed is between about 3 and 19 mph
(5 and 30 km/h),
- the braking assistance systems (ABS,
EBFD, EBA) have not failed,
- the trajectory control systems (ASR, DSC)
are not deactivated or faulty,
- the vehicle is not making a sharp turn,
- the system has not triggered in the last ten
seconds.
Operation
When your vehicle is too close to or
approaches the vehicle ahead too quickly, the
system automatically applies the brakes to
avoid a collision.
You are then warned by the display of a
message.
Your vehicle's brake lamps are lit to warn other
users.
The collision can be avoided if the speed
difference between your vehicle and the one
ahead is not more than 9 mph (15 km/h).
Above this threshold, the system will do
what is possible to avoid or reduce the
accident by lowering the speed of impact.
