A top-up is
essential,
due to the
risk that the
engine will
be prevented
from starting.Between
62 miles
and 0 miles
(100 km and

Malfunction of the SCR emissions
control system
Malfunction detection


If a malfunction is detected,
these warning lamps come on,
accompanied by an audible
signal and an "Emissions fault”
message.
The alert is triggered while driving, when the
fault is detected for the first time, and thereafter
when switching on the ignition for subsequent
journeys, while the cause of the fault persists.
If the fault is temporary, the alert
disappears during the next journey, after
self-diagnostic checks of the SCR emissions
control system.
Malfunction confirmed during the
permitted driving phase (between 685
miles and 0
miles (1,100 km and 0 km))
If the fault indication is still displayed
permanently after 31 miles (50 km) of driving, the
fault in the SCR system is confirmed.
The AdBlue warning lamp flashes, and an
"Emissions fault: Starting prevented in X
miles" or "NO START IN X miles" message is
displayed, indicating the driving range in miles or
kilometres.
While driving, the message is displayed every 30
seconds. The alert is repeated when switching
on the ignition.
You can continue driving for up to 685 miles
(1,100
km) before the engine immobiliser
system is triggered.
Have the system checked by a
CITROËN dealer or a qualified workshop
as soon as possible.
Starting prevented
Whenever the ignition is switched on, the
"Emissions fault: Starting prevented" or "NO
START IN" message is displayed.
To be able to restart the engine, contact a CITROËN dealer or a qualified
workshop.
Touch screen
The touch screen gives access to:
– the heating / air conditioning controls,
–

menus for adjusting settings for vehicle
functions and systems,
–


audio system and telephone controls and the
display of associated information,
and, depending on equipment, allows:
–


the display of alert messages and the visual
parking sensors information,
–


the permanent display of the time and the
exterior temperature (a blue warning lamp
appears when there is a risk of ice),
–


access to the internet services and navigation
system controls and the display of associated
information.
As a safety measure, the driver must
only carry out operations that require
sustained attention with the vehicle
stationary.
Some functions are not accessible when
driving.

Driving
automatically to preserve the remaining battery
charge.
Starting the engine
With the parking brake applied:
► With a manual gearbox, place the gear lever
in neutral then fully depress the clutch pedal.
► With an automatic gearbox, place the gear
selector in mode N or P then fully depress the
brake pedal.
► Insert the key into the ignition switch; the
system recognises the code.
► Unlock the steering column by simultaneously
turning the steering wheel and the key.
In certain cases, you may have to apply
significant force to move the steering
wheel (wheels on full lock, for example).
► With a petrol engine , operate the starter
motor by turning the key to position 3 without
pressing the accelerator pedal, until the engine
starts. Once the engine starts, release the key.
With petrol engines , after a cold start,
preheating the catalytic converter can
cause noticeable engine vibrations for
anything up to 2 minutes while stationary with
the engine running (accelerated idle speed).
► With a Diesel engine, turn the key to position
2, ignition on, to operate the engine preheating
system.
Before setting off
Nose weight
► Distribute the load in the trailer so that the
heaviest items are as close as possible to the
axle and the nose weight (at the point where it
joins your vehicle) approaches the maximum
permitted without exceeding it.
Tyres
► Check the tyre pressures of the towing
vehicle and of the trailer , observing the
recommended pressures.
Lighting
► Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine CITROËN towing device is
used, the rear parking sensors will be
deactivated automatically to avoid the audible
signal.
When driving
Cooling
Towing a trailer uphill increases the temperature
of the coolant. The maximum towable load
depends on the gradient and the exterior
temperature. The cooling capacity of the fan
does not increase with engine speed.
►

Reduce speed and lower the engine speed,
so as to limit the heating-up. In all cases, pay attention to the coolant
temperature.
If this warning lamp and the
STOP
warning lamp come on, stop the vehicle
and switch off the engine as soon as possible.
Brakes
Braking distances are increased when towing a
trailer. To avoid overheating of the brakes, the
use of engine braking is recommended.
Side wind
Bear in mind the increased susceptibility to the
wind that the vehicle will have.
Anti-theft protection
Electronic immobiliser
The key contains an electronic chip which has a
special code. When the ignition is switched on,
this code must be recognised in order for starting
to be possible.
This electronic engine immobiliser locks the
engine management system a moment after
the ignition is switched off, and prevents
unauthorised engine starting.
In the event of a fault, you are informed
by illumination of this warning lamp, an
audible signal and a message in the screen.
In this case, your vehicle will not start; contact
a CITROËN dealer or a qualified workshop as
soon as possible.
Starting / Switching off the
engine with the key
Key ignition switch

It has 3 positions:
– 1. Stop: inserting and removing the key ,
steering column locked.
–

2. Ignition : steering column unlocked, ignition
on, Diesel preheating, engine running.
–


3. Starting
.
Avoid attaching heavy objects to the key or the remote control. It would weigh
down on its shaft in the ignition switch and
could cause a malfunction.
Ignition on position
It allows the use of the vehicle's electric
equipment or portable devices to be charged.
Once the state of charge of the battery drops to
the reserve level, the system switches to energy
economy mode : the power supply is cut off

75
Driving
6The system adapts its gear shift recommendation according to the driving
conditions (slope, load, etc.) and the driver’s
requirements (request for power, acceleration,
braking, etc.).
The system never suggests:
–

engaging first gear
.
–

engaging a lower gear
.
–

engaging reverse.
With a manual gearbox, the arrow may
be accompanied by the recommended
gear. The system always suggests changing
to a higher gear when this is necessary.
Hill start assist
This system keeps your vehicle briefly stationary
(for approximately 2 seconds) when making a hill
start, while you transfer your foot from the brake
pedal to the accelerator pedal.
This system is only active when:
–

the vehicle is completely stationary
, with your
foot on the brake pedal,
–

certain slope conditions are met,
–


the driver
’s door is closed.
Do not leave the vehicle while it is being
held temporarily by hill start assist.
If someone needs to get out of the vehicle
with the engine running, apply the parking
brake manually. After that, ensure that the
parking brake indicator lamp and the indicator
lamp P in the electric parking brake control
lever are on fixed.
The hill start assist function cannot be deactivated. However, use of the parking
brake to immobilise the vehicle interrupts its
operation.
Operation

Facing uphill, with the vehicle stationary,
the vehicle is held for a short time when you
release the brake pedal:
–

provided you are in first gear or neutral with a
manual gearbox.
–


provided you are in mode D

or M with an
automatic gearbox.


Facing downhill, with the vehicle stationary
and reverse gear engaged, the vehicle is held
for a short time when you release the brake
pedal.
Malfunction
This warning lamp comes on in the event of a malfunction, accompanied by an
onscreen message.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Tyre under-inflation detection
This system automatically checks the pressures
of the tyres while driving.
It compares the information given by the wheel
speed sensors with reference values, which
must be reinitialised every time the tyre
pressures are adjusted or a wheel changed.

90
Driving
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

91
Driving
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.
