Operating principle
Using the radar sensor, the system calculates
the distance separating the vehicle
from the one in front and alerts the
driver if there is a risk of a front-end collision.
The driver can then brake the vehicle
to limit the damage arising from a
collision.
Note: make sure that the radar sensor 1
is not obscured (by dirt, mud, snow etc.
or by the fitting of accessories such as
bullbars).
Operation
While driving (at speeds of between 20
and 85 mph (30 and 140 km/h) ), if there
is a risk of collision with the vehicle in
front, the warning light 4 will be displayed
on the instrument panel in red,
alongside a beep.
If the driver depresses the brake pedal
and the system still detects a risk of
collision, the brake force is increased. If
the driver fails to react following an alert
of an imminent collision, the system activates
the brakes.
Activating or deactivating the
system
For vehicles fitted with a navigation
system
On the multifunction screen 5, select
the "Vehicle" menu, "Driving assistance",
and "Active braking", and then
choose "ON" or "OFF".
You can access menu "Driving assistance"
directly from button 6  . |
For vehicle not fitted with a
navigation system
- With the vehicle at a standstill, press
and hold the switch 7 OK to access
the settings menu,
- repeatedly press the control 8 up or
down until you reach the "Driving assistance"
menu. Press the switch 7
OK;
- repeatedly press control 8up or down
until you reach the "Active braking"
menu, then press the switch 7 OK.
Press the switch 7 OK again to activate
or deactivate the function:
function activated
function deactivated
The warning light 
is displayed on
the instrument panel when the system
is deactivated. This system is reactivated
each time the ignition is switched
on.
Conditions for non-activation
of the system
The system cannot be activated:
-
when the gear lever is in neutral;
-
when the parking brake is activated;
-
while cornering.
-
For 4-wheel drive vehicles, when
Electronic Stability Programme
(ESC) with understeer and traction
control are deactivated (please
see "Electronic Stability Programme
(ESC) with understeer and traction
control" above). Warning light
comes on.
Operating faults
When the system detects an operating
fault, the warning light lights up
on the instrument panel, with the message
"Active braking disconnected".
There are two possibilities:
- the system is temporarily disrupted
(for example: radar obscured by
dirt, mud, snow etc.). In this case,
park the vehicle and switch off the
engine. Clean the detection zone of
the radar. When you next start the
engine, the warning light and the
message go out
- if this is not the case, this may arise
from another cause; contact an
Approved Dealer.
Consult an approved dealer.
| The system A only detects vehicles
driving in the same direction of traffic.
The system cannot detect motorcycles
because of the difficulty in
forecasting their trajectory. |
| Active emergency braking This function is an additional
driving aid. This function is not under any circumstances intended to
replace the due care
and attention of the driver, who should at all times be in control of
the vehicle. The triggering of this function may be
delayed or prevented when the system detects clear signs of control of
the vehicle by the driver (action on the steering
wheel, pedals etc.).
System servicing/repairs
Only an authorised dealer is qualified to service the system.
In the event of system disturbance
Some conditions can disturb or damage the operation of the system,
such as:
- a complex environment (metal bridge, tunnel etc.);
- poor weather conditions (snow, hail, black ice etc.);
Risk of inadvertent braking. |
Limitation of the system operation
- The system will only respond to vehicles which are moving or
which have been sensed as moving.
- The radar area should be kept clean and free of any
modifications in order to ensure the proper operation of the
system.
- The system cannot respond to small vehicles such as motorbikes,
bicycles or pedestrians as effectively as to other vehicles.
- The system may not operate properly when the road surface is
slippery (rain, snow, black ice etc.).
Deactivating the function
You must disable the function if:
- the brake lights are not functioning;
- the front of the vehicle has undergone an impact or been
damaged;
- the vehicle is being towed (breakdowns);
Halting the function
You can halt the active braking function at any time by tapping the
accelerator pedal or by turning the steering wheel in a avoidance
manoeuvre.
In the event of the system behaving abnormally, deactivate it and
consult an authorised dealer. |
