speed setting to use with the speed limiter or
the programmable cruise control.
Recognition of
speed limit signs and
recommendation
The units for the speed limits (mph or
km/h) depend on the country you are
driving in.
This should be taken into account in order
to obser ve the speed limit.
For the system to operate correctly when
you change country, the units for speed in
the instrument panel must be set to those
for the country you are driving in.
The automatic reading of road signs is a
driving assistance system and does not
always display speed limits correctly.
The speed limit signs present on the road
always take priority over the display by the
system.
The system cannot in any circumstances
replace the need for vigilance on the part
of the driver.
The driver must observe the driving
regulations and must adapt the speed of
the vehicle to suit the weather and traffic.
It is possible for the system to not display
the speed limit if it does not detect a
speed limit sign within a preset period.
The system is designed to detect signs
that conform to the Vienna Convention on
road signs. To maintain correct operation of the
system: regularly clean the area in front of
the camera.
The internal sur face of the windscreen can
also become misted around the camera.
In humid and cold weather, demist the
windscreen regularly.
Principles
This system allows the speed limit detected by
the camera to be displayed in the instrument
panel.
The system also processes speed limit details
from the navigation system mapping.
This system allows the speed limit detected by
the camera to be displayed in the instrument
panel.
Specific speed limits, such as those for heavy
goods vehicles, are not displayed.
The display of the speed limit in the instrument
panel is updated as you pass a speed limit sign
intended for cars (light vehicles).

I t takes account of:
-

v
ehicles driving in the same direction or
stationary,
-

p
edestrians in the traffic lane (bicycles,
motorcycles, animals and objects on the
road are not necessarily detected).
This system is designed to assist the
driver and improve road safety.
It is the driver's responsibility to
continuously monitor the state of the
traffic, observing the driving regulations.
This system does not replace the need for
vigilance on the part of the driver.
As soon as the system detects a potential
obstacle, it prepares the braking circuit in
case automatic braking is needed. This
may cause a slight noise and a sense of
deceleration.
Operating limits
In the following cases, deactivating the
system via the vehicle's configuration menu is
recommended:
-
w
hen towing a trailer,
-

w
hen carrying long objects on roof bars or a
roof rack,
-

b
efore using an automatic car wash, with
the engine running,
-

b
efore placing the vehicle on a rolling stand
in a workshop,
-

w
hen the vehicle is being towed, with the
engine running,

fitted (depending on version),
-
fo

llowing impact damage to the windscreen
close to the detection camera,
-

i
f the brake lamps are not working.It is possible that warnings are not given,
are given too late or seem unjustified.
Consequently, always stay alert and be
prepared to react at any time to avoid an
accident.
Collision Risk Alert
Depending on the degree of risk of collision
detected by the system and the alert threshold
chosen by the driver, different levels of
alert can be triggered and displayed in the
instrument panel or on the head-up display. Level 1 (orange) : visual alert only,
signalling to you that the vehicle in
front is very close.
The message " Vehicle close" is
displayed.
This level of alert is based on the inter-vehicle
time between your vehicle and the vehicle in
front. Level 2 (red) : visual and audible
alert, warning you that a collision is
imminent.
The message " Brake!" is displayed.
This level of alert is based on the time before
collision. It takes into account the vehicle
dynamics, the speed of your vehicle and the
one in front, the environmental conditions, the
operating conditions of the vehicle (on a cur ve,
pedals pressed, etc.) to trigger the alert at the
relevant moment.
6
Driving

144
Where the speed of your vehicle is too
high approaching another vehicle, the first
level of alert may not be displayed: the
level 2 alert may be displayed directly.
Important: the level 1 alert is never
displayed when the " Close" trigger
threshold has been selected.
Modifying the alert trigger
threshold
This threshold determines how you wish
to be alerted of the presence of a moving
or stationary vehicle in front of you, or a
pedestrian present in your traffic lane.
The current threshold can be modified via the
vehicle configuration menu.
You can select one of three predefined
thresholds:
-
"Distant ",
-
"Normal ",
-
"Close ".
The last threshold selected is kept in memory
when the ignition is switched off.
Without audio system

braking assistance
If the driver brakes, but not sufficiently to avoid
a collision, this system will supplement the
braking, within the limits of the laws of physics.
This assistance will only be provided if you
press the brake pedal.
Active Safety Brake
This function, also called automatic emergency
braking, aims to reduce the speed of impact or
avoid a frontal collision by your vehicle where

If the camera has confirmed
the presence of a vehicle or a
pedestrian, this warning lamp
flashes once the function is acting
on the vehicle's brakes.
Using the camera, this function acts on the
vehicle's braking system.
Important : if operation of the
automatic emergency braking is
triggered, you should take back
control of your vehicle and brake
with the pedal to add to or finish the
automatic braking action.
The driver can take back control of the vehicle
at any time by sharply turning the steering
wheel and/or pressing the accelerator pedal.
The point at which braking is triggered
may be adjusted according to the driving
actions from the driver, such as movement
of the steering wheel or pressing the
accelerator pedal.
Operation of the function may be felt by
slight vibration in the brake pedal.
If the vehicle comes to a complete stop,
the automatic braking is maintained for 1
to 2

seconds. With a manual gearbox, in the event of
automatic emergency braking until the
vehicle comes to a complete stop, the
engine may stall.
With an automatic gearbox, in the event
of automatic emergency braking until the
vehicle comes to a complete stop, keep
the brake pedal down to stop the vehicle
from starting off again.
Specific conditions for operation
The vehicle's speed must be between 3 mph
a nd 53 mph (5 km/h and 85 km/h) when a
moving vehicle is detected.
The vehicle's speed must not exceed 50
mph
(80 km/h) when a stopped vehicle is detected.
The vehicle's speed must not exceed 37
mph
(60
km/h) when a pedestrian is detected.
The ESC system must not be defective.
The ASR system must not be deactivated.
All passenger seat belts must be fastened.
Driving at a steady speed on roads with few
bends is required.
After an impact, the function automatically
stops operating. Consult a CITROËN
dealer or a qualified workshop to have the
system checked.
