On vehicles fitted with a manual gearbox,
the arrow may be accompanied by the
gear recommended.
Hill start assist
System which keeps your vehicle immobilised
temporarily (approximately 2 seconds) when
starting on a gradient, the time it takes to
move your foot from the brake pedal to the
accelerator pedal.
It is only active when:
-

t
he vehicle is completely stationary, with
your foot on the brake pedal,
-

c
ertain slope conditions are met,
-

t
he driver’s door is closed.Do not leave the vehicle while it is being
held temporarily in the hill start assist
phase.
If you need to leave the vehicle with the
engine running, apply the parking brake
manually then ensure that the parking
brake warning lamp lights up fixed on the
instrument panel. The hill start assist function cannot be
deactivated. However, use of the parking
brake to immobilise the vehicle interrupts
its operation.
On an ascending slope, with the vehicle
stationar y, the vehicle is held for a shor t
time when you release the brake pedal:
With a manual gearbox, if you are in first gear
or in neutral.
With an automatic gearbox, if you are in
position D or M . On a descending slope, with the vehicle
stationary and reverse gear engaged, the
vehicle is held for a shor t time when you
release the brake pedal.
Malfunction
If a fault in the system occurs, this warning
lamp comes on accompanied by a message.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Stop & Start
The Stop & Start system puts the engine
t emporarily into standby – STOP mode – during
stops in traffic (red lights, traffic jams, etc.). The
engine restarts automatically – START mode –
as soon as you want to move off.
The restart takes place instantly, quickly and
silently.
Per fect for urban use, the Stop & Start system
reduces fuel consumption and exhaust
emissions as well as the noise level when
stationary.

Stop & Star t time counter
(minutes/seconds or hours/minutes)
For your comfort, during parking
manoeuvres, STOP mode is not available
for a few seconds after coming out of
reverse gear.
The Stop & Start system does not affect
the functionality of the vehicle, such as for
example, braking, power steering, etc. Never refuel with the engine in STOP
mode; you must switch off the ignition with
the "START/STOP" button.
If your vehicle is fitted with this system, a time
counter calculates the sum of the periods in
STOP mode during a journey.
It resets to zero every time the ignition is
switched on.
Special cases: STOP mode not
available
STOP mode is not activated when:
- t he vehicle is on a steep slope (uphill or
downhill),
-

t
he driver's door is open,
-

t
he driver's seat belt is not fastened,
-

t
he vehicle has not exceeded 6 mph
(10
km/h) since the last engine start,
-

t
he engine is needed to maintain a
comfortable temperature in the passenger
compartment,
-

d
emisting is active,
-

Temporarily exceeding the
speed setting
F Press firmly on the accelerator pedal,
going beyond the point of resistance, to
exceed the programmed speed limit.
The speed limiter is deactivated temporarily
and the displayed programmed speed flashes.
On a steep descent or in the event of
sharp acceleration, the speed limiter will
not be able to prevent the vehicle from
exceeding the programmed speed.
When the limit speed is exceeded but this is not
due to action by the driver, there is an audible
signal to complete the alert.
Once the speed of the vehicle returns to
the programmed setting, the speed limiter
functions again: the display of the programmed
speed setting becomes steady again.
Switching off
F Turn the thumbwheel 1 to the 0 position: the display of information about the speed
limiter disappears. Flashing dashes indicate a fault with the speed
limiter.
Have them checked by a CITROËN dealer or a
qualified workshop.
The use of mats not approved by
CITROËN may inter fere with the operation
of the speed limiter.
To avoid any risk of jamming of the pedals:
-
e
nsure that the mat is positioned
c o r r e c t l y,
-
d
o not fit one mat on top of another.
Malfunction
Cruise control
System which automatically
maintains the speed of the vehicle
at the value programmed by the
driver, without any action on the
accelerator pedal.The cruise control is switched on

manually.
It requires a minimum vehicle speed of
25 mph (40 km/h) as well as:
-
w
ith a manual gearbox, the
engagement of third gear or higher,
-
w
ith an automatic gearbox, the
engagement of the selector in mode D
or of second gear or higher in mode M .
The cruise control is paused manually or by
pressing the brake or clutch pedal or if the ESC
system is invoked for safety reasons.
Once switched on, you can pause the cruise
control at any time by pressing button 4 : the
screen confirms the pause.
Switching off the ignition cancels any
programmed speed setting.
The cruise control system is a driving aid
that cannot, in any circumstances, replace
the need to obser ve speed limits, nor the
need for vigilance on the part of the driver.
As a safety measure, you are advised to
keep your feet near the pedals at all times.

F Pressing button 4 again restores operation of the cruise control (ON).
Modifying the cruise speed
setting
The cruise control must be active.
As a precaution, it is recommended
that the cruise speed chosen be close
to the current speed of your vehicle, so
as to avoid any sudden acceleration or
deceleration of the vehicle.
To modify the cruise speed setting from the
current speed of the vehicle:
F

i
n steps of +/- 1 mph (km/h), make repeated
short presses on button 2 or 3 ,
F

c
ontinuously, in increments of +/- 5 mph
(km/h), press and hold button 2 or 3 .Take care: pressing and holding button 2
or 3
results in a rapid change in the speed
of your vehicle.
To modify the cruise speed setting using
memorised speed settings and from the touch
screen:
F
p
ress button 5 to display the six memorised
speed settings,
F
p
ress the button for the desired speed
setting.
This setting becomes the new cruise speed.
To modify the cruise speed setting using the
speed suggested by the speed limit recognition
system:
F

t
he speed suggested is displayed in the
instrument panel,
F

m
ake a first press on button 5; a message
is displayed to confirm the memorisation
request,
F

p
ress button 5 again to save the suggested
speed.
The speed is then displayed in the instrument
panel as the new speed setting.
Temporarily exceeding the
speed setting
If needed (for overtaking purposes, etc.),
the driver can exceed the speed setting by
pressing the accelerator pedal.
The cruise control is temporarily overridden
and the speed setting flashes.
To return to the speed setting, release the
accelerator pedal.
Once the vehicle has returned to the
programmed speed, the cruise control takes
over again: the display of the programmed
speed setting becomes steady again.
On a steep descent, the cruise control will
not be able to prevent the vehicle from
exceeding the programmed speed.
You may have to brake to control the speed of
your vehicle. In this case, the cruise control is
automatically paused.
To activate the system again, with the speed
of the vehicle above 25 mph (40 km/h), press
button 4 .

Switching off
F Turn thumbwheel 1 to position 0: the cruise control information disappears from the
screen.
Malfunction
Flashing dashes indicate a fault with the cruise
control system.
Have it checked by a CITROËN dealer or a
qualified workshop. Use the cruise control only where the
driving conditions allow driving at a
constant speed for a while and at an
adequate safe distance.
Do not activate the cruise control in urban
areas, in heavy traffic, on winding or steep
roads, on slippery or flooded roads, or in
conditions of poor visibility (heavy rain,
fog, falling snow etc.).
In some circumstances, it may not be
possible to maintain or reach the cruise
speed set: towing, vehicle heavily loaded,
steep climb.
The use of mats not approved by
CITROËN may inter fere with the operation
of the cruise control.
To avoid any risk of jamming of the pedals:
-

e
nsure that the mat is positioned
c o r r e c t l y,
-

d
o not fit one mat on top of another.
Collision Risk Alert and
Active Safety Brake
Activation and operating
conditions
This system is a driving aid that includes three
functions.
Collision Risk Alert: it warns the driver if their
vehicle is at risk of collision with the vehicle in
front or a pedestrian present in their traffic lane.
Intelligent emergency braking assistance :
it supplements the braking action taken by the
driver if this is inadequate.
Active Safety Brake: it intervenes following
the alert if the driver does not react quickly
enough and does not operate the vehicle's
brakes.
If the driver fails to act, it contributes
towards avoiding a collision or limiting
its severity by reducing the speed of your
vehicle.
The vehicle has a camera located at the top of
the windscreen.
Driving

143
The system is activated from 3 mph (5 km/h).
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,
-

w
hen a "space-saver" type spare wheel is
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
With audio systemIntelligent emergency
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
the driver fails to react.

Driving

145
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.
Deactivation/Activation
By default, the system is automatically
activated at every engine start-up.
The system can be deactivated or activated via
the vehicle settings menu. Deactivation of the system is
signalled by the illumination of this
indicator lamp, accompanied by the
display of a message.
