Driving
6Where 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 not displayed
when there is a stationary obstacle or when
the "Close" trigger threshold has been
selected.
Modifying the alert trigger threshold
This threshold determines how you wish to be
warned 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 pre-defined
thresholds:
–
"Distant",
–
"Normal",
–
"Close".
The last threshold selected is memorised when
the ignition is switched off.
Intelligent 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, intervenes following the alerts if the
driver does not react quickly enough and does
not operate the vehicle's brakes.
It aims to reduce the speed of impact or avoid a
collision where the driver fails to react.
Operation
The system operates under the following
conditions:
–

The vehicle's speed does not exceed 37 mph
(60 km/h) when a pedestrian is detected.
–


The vehicle's speed does not exceed 50 mph
(80 km/h) when a stationary vehicle is detected.
– The vehicle's speed is between 3 mph and
53 mph (5 km/h and 85 km/h) when a moving
vehicle is detected.
This warning lamp flashes (for approximately 10 seconds) as soon as
the function acts on the vehicle’s braking.
With an automatic gearbox, in the event of
automatic emergency braking until the vehicle
comes to a complete stop, keep the brake
pedal pressed down to prevent the vehicle from
starting off again.
With a manual gearbox, in the event of automatic
emergency braking until the vehicle comes to a
complete stop, the engine may stall.
The driver can maintain control of the vehicle at any time by sharply turning the
steering wheel and/or sharply 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.
Deactivation / Activation
By default, the system is automatically activated
at every engine start.
It is set via the Driving / Vehicle touch
screen menu.

88
Driving
The following situations may interfere with the operation of the system or
prevent it from working:
– lane markings absent, worn, hidden (snow,
mud) or multiple (roadworks);
– close to the vehicle ahead (lane markings
not detected);
– roads that are narrow, winding, etc.
Lane Departure Warning
System
Refer to the General recommendations on the
use of driving and manoeuvring aids .
This system, using a camera which recognises
solid or broken lines, detects the involuntary
crossing of longitudinal traffic lane markings on
the ground.
If the driver's attention drops and the speed
is higher than 37 mph (60 km/h), the system
triggers a warning if there is an unexpected
change of direction.
This system is particularly useful on motorways
and main roads.


Deactivation of the system is signalled by
the illumination of this warning lamp,
accompanied by the display of a message.
Malfunction
In the event of a fault with the system, you
are alerted by the fixed illumination of this
warning lamp, accompanied by the display of a
message and an audible signal.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Distraction detection
Refer to the General recommendations on the
use of driving and manoeuvring aids .
Take a break in case of feeling tired or at least
every 2 hours.
The function consists of the "Coffee Break Alert"
system combined with the "Driver Attention
Warning" system.
These systems are in no way designed to keep the driver awake or to prevent
the driver from falling asleep at the wheel.
It is the driver’s responsibility to stop if feeling
tired.
Activation / Deactivation
It is set via the Driving / Vehicle touch
screen menu.
The state of the system stays in the memory
when the ignition is switched off.
Coffee Break Alert
The system triggers an alert as soon as it detects that the driver has not taken a
break after two hours of driving at a speed above
40 mph (65
km/h).
This alert is issued via the display of a message
encouraging the driver to take a break,
accompanied by an audible signal.
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:
–

With the engine running, the vehicle has been
stationary for more than 15 minutes.
–


The ignition has been switched off for a few
minutes.
–


The driver's seat belt is unfastened and their
door is opened.
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 Attention Warning

Using a camera placed at the top of the
windscreen, the system assesses the
driver's level of vigilance, fatigue or distraction 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)).
At a first-level alert, the driver is warned by the
“Take care! ” message, accompanied by an
audible signal.
After three first-level alerts, the system triggers
a further alert with the message " Dangerous
driving: take a break", accompanied by a more
pronounced audible signal.
In certain driving conditions (poor road
surface or strong winds), the system may
give alerts independent of the driver's level of
vigilance.

Blind Spot Monitoring
System
Refer to the General recommendations on the
use of driving and manoeuvring aids .


This system includes sensors, placed on the
sides of the bumpers, and warns the driver of
the potentially dangerous presence of another
vehicle (car, truck, motorcycle) in the blind spot
areas of their vehicle (areas hidden
from the
driver's field of vision).


The warning is given by a fixed warning lamp
that appears in the door mirror on the side in
question:
–

immediately
, when being overtaken;
–

after a delay of about one second, when
overtaking a vehicle slowly

.
Activation / Deactivation
It is set via the Driving / Vehicle touch
screen menu.

or other objects; they may hamper correct
operation of the system.
Parking sensors
Refer to the General recommendations on the
use of driving and manoeuvring aids.


Using sensors located in the bumper, this
system signals the proximity of obstacles
(e.g. pedestrian, vehicle, tree, barrier) present in
their field of detection.
Rear parking sensors
The system is switched on by engaging reverse
gear, which is confirmed by an audible signal.
The system is switched off when disengaging
reverse gear.
The state of the system stays in the memory
when switching off the ignition.
The system is automatically deactivated
when towing with a towing device
approved by CITROËN.
Conditions for operation
– All vehicles are moving in the same direction
and in adjacent lanes.
–

The speed of your vehicle must be between 7
and 87 mph (12 and 140

km/h).
–

When overtaking a vehicle, the speed
difference is less than 6

mph (10 km/h).
–

When overtaken by a vehicle, the speed
difference is less than 16

mph (25 km/h).
–

T
raffic is flowing normally.
–

Overtaking a vehicle over a certain period of
time and the vehicle being overtaken remains in
the blind spot.
–


Y
ou are driving on a straight or slightly curved
road.
–

Y
our vehicle is not pulling a trailer, a caravan,
etc.
Operating limits



No alert is triggered in the following conditions:
– In the presence of non-moving objects (parked
vehicles, barriers, street lamps, road signs, etc.).
–

Oncoming traffic.
–


Driving on a winding road or a sharp corner
.
–

When overtaking or being overtaken by a very
long vehicle (lorry

, bus, etc.) that is detected
in the rear blind spot but is also present in the
driver’s front field of vision.
–

When overtaking quickly
.
–

In very heavy traffic: vehicles detected in
front and behind are confused with a lorry or a
stationary object.
Malfunction
In the event of a malfunction, you are warned by
the display of a message.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
The system may suffer temporary interference in certain weather conditions
(rain, hail, etc.).
In particular, driving on a wet surface or
moving from a dry area to a wet area can
cause false alerts (for example, the presence
of a fog of water droplets in the blind spot
angle is interpreted as a vehicle).
In bad or wintry weather, ensure that the
sensors are not covered by mud, ice or snow.
Take care not to cover the warning zone in
the door mirrors or the detection zones on the
front and rear bumpers with adhesive labels

6or other objects; they may hamper correct
operation of the system.
Parking sensors
Refer to the General recommendations on the
use of driving and manoeuvring aids.


Using sensors located in the bumper, this
system signals the proximity of obstacles
(e.g.
pedestrian, vehicle, tree, barrier) present in
their field of detection.
Rear parking sensors
The system is switched on by engaging reverse
gear, which is confirmed by an audible signal.
The system is switched off when disengaging
reverse gear.
Audible assistance

The system signals the presence of obstacles
which are both within the sensors’ detection zone
and in the vehicle path defined by the direction of
the steering wheel.


Depending on version, in the example shown,
only the obstacles present in the shaded area
will be signalled by the audible assistance.
The proximity information is given by an
intermittent audible signal, the frequency of
which increases as the vehicle approaches the
obstacle.
When the distance between the vehicle and
the obstacle becomes less than about thirty
centimetres, the audible signal becomes
continuous.
The sound emitted by the speaker (right or
left) indicates the side on which the obstacle is
located.
Adjusting the audible signalWith CITROËN Connect Radio or
CITROËN Connect Nav, pressing
this button opens the window for adjusting the
volume of the audible signal.
Visual assistance

It supplements the audible assistance, without
taking account of the vehicle's trajectory, by
displaying bars on the screen that represent the
distance between the obstacle and the vehicle
(white: more distant obstacles, orange: close
obstacles, red: very close obstacles).
When the obstacle is very close, the "Danger"
symbol is displayed on the screen.
Front parking sensors
In addition to the rear parking sensors, the front
parking sensors are triggered when an obstacle
is detected in front and the speed of the vehicle
is still below 6 mph (10
km/h).

92
Driving
The front parking sensors are interrupted if the
vehicle stops for more than three seconds in
forward gear, if an obstacle is no longer detected
or when the speed of the vehicle exceeds 6 mph
(10
km/h).
The sound emitted by the speaker (front or rear) locates the obstacle in relation to
the vehicle, in the vehicle trajectory, in front or
behind.
Deactivation / Activation
It is set via the Driving / Vehicle touch
screen menu.
The state of the system stays in the memory
when the ignition is switched off.
The rear parking sensors system will be deactivated automatically if a trailer or
bicycle carrier is connected to a towing device
installed in accordance with the
manufacturer's recommendations.
Operating limits
If the boot is heavily loaded, the vehicle may tilt,
affecting distance measurements.
Malfunction
In the event of a malfunction when
changing into reverse, this warning lamp
comes on on the instrument panel, accompanied
by an onscreen message and an audible signal
(short beep).
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Reversing Camera
Refer to the General recommendations on the
use of driving and manoeuvring aids .


The reversing camera is automatically activated
when reverse gear is engaged.
The image is displayed on the touch screen.
The reversing camera function may be
supplemented with parking sensors.


The representation with overlaid lines helps with
the manoeuvre.
They are represented as lines marked "on the ground" and do not indicate the
position of the vehicle in relation to tall
obstacles (e.g. other vehicles).
Some distortion of the image is normal.
It is normal to have a part of the number plate
showing at the bottom of the screen.
The blue lines 1 represent the general direction
of the vehicle (the gap represents the width of
your vehicle without the mirrors).
The red line 2 represents a distance of about
30

cm beyond the edge of your vehicle's rear
bumper.
The green lines 3 represent distances of about 1
and 2 metres beyond the edge of your vehicle's
rear bumper.
The turquoise blue curves 4 represent the
maximum turning circle.
Opening the tailgate causes the display
to disappear.

Practical information
Compatibility of fuels
Petrol fuels conforming to the EN228 standard
containing up to 5% and 10% ethanol
respectively.

Diesel fuels conforming to the EN590, EN16734
and EN16709 standards and containing up to
7%, 10%, 20% and 30% fatty acid methyl ester
respectively. The use of B20 or B30 fuels, even
occasionally, imposes special maintenance
conditions referred to as "Arduous conditions".

Paraffinic Diesel fuel conforming to the EN15940
standard.
The use of any other type of (bio) fuel (vegetable or animal oils, pure or diluted,
domestic fuel, etc.) is strictly prohibited (risk
of damage to the engine and fuel system).
The only fuel additives authorised for use are those that meet the B715001 (petrol)
or B715000 (Diesel) standards.
Diesel at low temperature
At temperatures below 0 °C (+32 °F), the
formation of paraffins in summer-type Diesel fuels could prevent the engine from operating
correctly
. In these temperature conditions, use
winter-type Diesel fuel and keep the fuel tank
more than 50 % full.
At temperatures below -15 °C (+5 °F) to avoid
problems starting, it is best to park the vehicle
under shelter (heated garage).
Travelling abroad
Certain fuels could damage your vehicle’s
engine.
In certain countries, the use of a particular
fuel may be required (specific octane rating,
specific trade name, etc.) to ensure correct
operation of the engine.
For all additional information, consult a dealer.
Refuelling
Fuel tank capacity (depending on version):
approximately 47 or 50 litres (petrol) or
approximately 45 or 50 litres (Diesel).
Reserve level: approximately 5 litres.
Low fuel level
When the low fuel level is reached, this
warning lamp in the instrument panel
comes on, accompanied by an audible warning,
a message and the last bar of the fuel gauge
flashes in red.
When it first comes on, about 5 litres of fuel
remain in the tank.
This warning lamp will come on every time
the ignition is switched on, accompanied by a
message and an audible signal, until a sufficient
addition of fuel is made. This audible signal and
message are repeated with increasing frequency
as the fuel level drops and approaches " 0".
You must refuel as soon as possible to avoid
running out of fuel.
For more information on Running out of
fuel (Diesel), refer to the corresponding
section.
Stop & Start
Never refuel with the engine in STOP
mode; you must switch off the ignition.
Refuelling
Additions of fuel must be of at least 5 litres, in
order to be registered by the fuel gauge.
Opening the filler cap may create a noise caused
by an inrush of air. This vacuum is entirely
normal, resulting from the sealing of the fuel
system.
To refuel in complete safety:
►

Y
ou must switch off the engine.
