Malfunction
When the ignition is on, the lighting
of this warning lamp, accompanied
by an audible signal and a message
in the screen, indicates a gearbox
fault.
In this case, the gearbox switches to back-up
mode and is locked in 3
rd gear. You may feel
a substantial knock when changing from P
to R and from N to R. This will not cause any
damage to the gearbox.
Do not exceed 60

mph (100 km/h), local speed
restrictions permitting.
Contact a CITROËN dealer or a qualified
workshop as soon as possible.
There is a risk of damage to the gearbox:
-

i

f you press the accelerator and brake
pedals at the same time,
-

i

f you force the movement of the
selector from position P to another
position when the battery is flat.
To reduce fuel consumption when at
a prolonged standstill with the engine
running (traffic jam, etc.), put the
selector in position N and apply the
parking brake. If your vehicle has an automatic gearbox,
never try to start the engine by pushing
the vehicle.
Gear efficiency indicator
System which reduces fuel consumption by
recommending the most appropriate gear.
Operation
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one (or more) gear(s). You can
follow this instruction without engaging the
intermediate gears.
Gear shift recommendations should not be
considered obligatory. The configuration of the
road, the amount of traffic and safety remain
determining factors when choosing the best
gear. The driver thus remains responsible
for deciding whether to follow or ignore the
system's instructions.
This function cannot be deactivated.
With an automatic gearbox, the system is
only active in manual mode. On BlueHDi Diesel versions with manual
gearbox, in certain driving conditions the
system may suggest changing into neutral so
that the engine can go into standby (STOP
mode of Stop & Start). In this case, N is
displayed in the instrument panel.
Example:
-

Y
ou are in 3
rd g e a r.
-
Y
ou press the accelerator pedal.
-

T

he system may suggest that you engage a
higher gear.
The system adapts its gear change
recommendations according to the
driving conditions (slope, load, etc.)
and the demands of the driver (power,
acceleration, braking, etc.).
The system never suggests:
-
e

ngaging first gear,
-
enga

ging reverse gear,
-
enga

ging a lower gear.
The information appears in the instrument
panel in the form of an arrow.
Driving

129
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.

For more information on the Speed limiter
or Cruise control , refer to the corresponding
section. With this button, you can select a memorised
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).

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

-
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.

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.

Malfunction
There may be interference in the operation
of the camera or it may not work at all in
the following situations:
-
p
oor visibility (inadequate street
lighting, falling snow, heavy rain, dense
fog, etc.),
-

d
azzle (headlamps of an oncoming
vehicle, low sun, reflections on a damp
road, leaving a tunnel, alternating shade
and light, etc.),
-

c
amera masked (mud, frost, snow,
condensation, etc.).
In these situations, detection performance
may be reduced.
Clean the windscreen regularly,
particularly 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.
Do not allow snow to accumulate on the
bonnet or roof of the vehicle as this could
mask the camera's view.
Fatigue detection system
Take a break as soon as you feel tired or at
least every two hours. The system cannot in any circumstances
replace the need for vigilance on the part
of the driver.
Do not take the wheel if you are tired.
Activation/Deactivation
The system is activated or deactivated via the
vehicle configuration menu.
Without audio system
F In the " DRIVE ASSIST " menu on the
instrument panel display, activate/deactivate
" VIGILANCE ALT " (Fatigue Detection
S yste m).
With audio system
F In the " Personalisation-
configuration " menu, activate/
deactivate " Fatigue Detection
System ".
With touch screen
F In the Driving/Vehicle menu,
select the " Vehicle settings "
tab, then " Security" and
activate/deactivate " Fatigue
Detection System ".
Driving time warning
The system triggers an alert once it
detects that the driver has not taken
a break after two hours of driving at
a speed above 40
mph (65 km/h).
In the event of a fault with the
system, you are alerted by the
illumination of this warning lamp,
accompanied by the display of a
message and an audible signal.
This alert takes the form of a display message
encouraging you to take a break, accompanied
by an audible signal.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Driving

147
If the driver does not follow this advice, the
alert is repeated hourly until the vehicle is
stopped.
The system resets itself if one of the following
conditions is met:
-
e
ngine running, the vehicle has been
stationary for more than 15


minutes,
-

t
he ignition has been switched off for a few
minutes,
-

t
he driver's seat belt is unfastened and their
door is open.
As soon as the speed of the vehicle drops
below 40
mph (65 km/h), the system goes
into standby.
The driving time is counted again once the
speed is above 40
mph (65 km/h).
Driver inattention alert
Depending on version, the "Driving time
warning" may be combined with the "Driver
inattention alert". Using a camera placed at the top
of the windscreen, the system
assesses the driver's level of
vigilance by identifying variations
in trajectory compared to the lane
markings.
This system is particularly suited to fast roads
(speed higher than 40 mph (65 km/h)).
When the system interprets the behaviour of
the vehicle as indicating a certain fatigue or
inattention threshold on the part of the driver, it
triggers the first level of alert.
The driver is then alerted by the message
" Ta k e c a r e ! ", accompanied by an audible
signal. After three first level alerts, the system triggers
a new alert with the message "
Take a break!",
accompanied by a more pronounced audible
signal.
In certain driving conditions (poor road
sur face or strong winds), the system may
give alerts independent of the driver's
level of vigilance.
The following situations may interfere with
the operation of the system or prevent it
working:
-
p
oor visibility (inadequate lighting of
the roadway, falling snow, heavy rain,
dense fog, etc.),
-
d
azzle (headlamps of an oncoming
vehicle, low sun, reflections on a damp
road, leaving a tunnel, alternating
shade and light, etc.),
-
w
