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.

Ease of use and comfort
The manual air conditioning operates when the
engine is running.
1.Recirculation of interior air.
2. Temperature adjustment.
3. Air distribution adjustment.
4. Air flow adjustment.
5. Air conditioning on / off.
► Select the Air conditioning touch
screen menu to display the controls page
for the system.
Temperature adjustment
► Press one of the arrows 2, or move the
slider from blue (cold) to red (hot) to adjust the
temperature to your liking.
Air flow adjustment
► Press one of the buttons 4 to increase or
decrease the speed of the air booster fan.
The air flow symbol (a fan) is filled in
progressively as the speed of the fan is
increased.
By reducing the air flow to a minimum, you are
stopping ventilation.
Avoid driving for too long without ventilation - risk of misting and
deterioration of air quality!
Air distribution adjustment
You can vary the air distribution in the passenger
compartment using the buttons 3.
Advice
Using the ventilation and air
conditioning system
►

T

o ensure that air is distributed evenly,
keep the external air intake grilles at the base
of the windscreen, the nozzles, the vents, the
air outlets and the air extractor in the boot
free from obstructions.
►

Do not cover the sunshine sensor located
on the dashboard; this sensor is used to
regulate the automatic air conditioning
system.
►


Operate the air conditioning system for at
least 5 to 10 minutes once or twice a month to
keep it in perfect working order

.
►

If the system does not produce cold air
,
switch it off and contact a CITROËN dealer or
a qualified workshop.
When towing the maximum load on a steep
gradient in high temperatures, switching off
the air conditioning increases the available
engine power, enhancing the towing capacity.
Avoid driving for too long with the ventilation off or with prolonged operation
of interior air recirculation. Risk of misting and
deterioration of the air quality!
If the interior temperature is very high
after the vehicle has stood for a long
time in the sunshine, air the passenger
compartment for a few moments.
Put the air flow control at a setting high
enough to quickly change the air in the
passenger compartment.
Condensation created by the air
conditioning results in a discharge of
water underneath the vehicle. This is perfectly
normal.
Servicing the ventilation and air
conditioning system
►

Ensure that the passenger compartment
filter is in good condition and have the filter
elements replaced regularly

.
We recommend using a composite passenger
compartment filter. Thanks to its special active
additive, this type of filter helps to purify the
air breathed by the occupants and keep the
passenger compartment clean (by reducing
allergic symptoms, unpleasant odours and
greasy deposits).
►

T

o ensure correct operation of the
air conditioning system, have it checked
according to the recommendations in the
Maintenance and Warranty Guide.
Stop & Start
The heating and air conditioning systems
only operate when the engine is running.
Temporarily deactivate the Stop & Start
system to maintain a comfortable temperature
in the passenger compartment.
For more information on the Stop & Start,
refer to the corresponding section.
Heating / Manual air
conditioning


The heating only operates when the engine is
running.

Lighting and visibility
4Switching off of the lamps when the
ignition is switched off
When the ignition is switched off, all of the
lamps turn off immediately, except for dipped
beam headlamps if automatic guide-me-home
lighting is activated.
Switching on the lighting after
switching off the ignition
To reactivate the lighting control, rotate the
ring to the "0" position - lights off, then to the
desired position.
When the driver's door is opened, a
temporary audible signal warns you that the
vehicle's lighting is on.
The lighting, with the exception of the
side lights, switch off automatically after a
maximum duration of thirty minutes to prevent
discharging of the battery.
In some weather conditions (e.g. low
temperature or humidity), misting on the
internal surface of the glass of the headlamps
and rear lamps is normal, and will disappear
after the lamps have been on for a few
minutes.
Travelling abroad
Vehicles equipped with halogen
headlamps:
If planning to use your vehicle in a country
that drives on the other side of the road, the
headlamp dipped beams must be adjusted to
avoid dazzling oncoming drivers. Contact a
CITROËN dealer or a qualified workshop.
Direction indicators

► Left: lower the lighting control stalk beyond
the point of resistance.
►

Right: raise the lighting control stalk beyond
the point of resistance.
Three flashes
► Press briefly upwards or downwards, without
going beyond the point of resistance; the
direction indicators will flash 3 times.
Parking lamps
Vehicle side marking by lighting the sidelamps
on the traffic side only.
►

Depending on version, within one minute
of switching off the ignition, move the lighting control stalk up or down, depending which side
the traffic is on (for example, when parking on
the left, moving the lighting control stalk upwards
turns on the right-hand sidelamps).
This is confirmed by an audible signal and the
lighting of the corresponding direction indicator
lamp on the instrument panel.
►


T
o switch off the parking lamps, return the
lighting control stalk to the central position.
Automatic illumination of headlamps
When the ring is at the “AUTO" position and
a low level of ambient light is detected by the
rain/sunshine sensor, the number plate lamps,
sidelamps and dipped beam headlamps are
switched on automatically, without any action on
the part of the driver. They may also come on if
rain is detected, at the same time as automatic
operation of the windscreen wipers.
As soon as the brightness returns to a sufficient
level or after the windscreen wipers are switched
off, the lamps are switched off automatically.
Malfunction
In the event of a malfunction of the
sunshine sensor, the lamps come on, this
warning lamp is displayed on the instrument
panel together with an audible signal and/or a
message.

44
Lighting and visibility
Contact a CITROËN dealer or a qualified
workshop.
Do not cover the sunshine sensor, linked
with the rain sensor and located at the
top centre of the windscreen behind the rear
view mirror; the associated functions would
no longer be controlled.
In fog or snow, the sunshine sensor may
detect sufficient light. In this case, the
lighting will not come on automatically.
Daytime running lamps/
sidelamps (LEDs)


The light-emitting diodes (LEDs) come on
automatically when the engine is started.
They provide the following functions:
–

Daytime running lamps (lighting control stalk
at position "

0" or "AUTO" with adequate light
level).
– Sidelamps (lighting control stalk in " AUT O"
position with low light level or "Sidelamps only”
or "Dipped/main beam headlamps").
In daytime running lamps mode, the
diodes are brighter.
Guide-me-home lighting
Automatic
When automatic lighting of the lamps is
activated, if the exterior light level is low, the
dipped beam headlamps automatically come on
when switching off the ignition.
You can activate/deactivate this function and adjust the guide-me-home lighting
duration in the Driving
/ Vehicle touch screen
menu.
Manual

The temporary illumination of the dipped beam
headlamps after the vehicle's ignition has been
switched off makes the driver's exit easier when
the light is poor.
Switching on
►

With the ignition off, "flash" the headlamps
using the lighting stalk.
►


Another “headlamp flash” switches the
function off.
Switching off
The manual guide-me lighting goes off
automatically at the end of a given period of
time.
Headlamp beam height
adjustment




To avoid causing a nuisance to other road users,
the height of the headlamp beams should be
adjusted according to the load in the vehicle.
0. (Initial adjustment) Driver only or driver + front passenger
-. Driver + front passenger + rear passengers
1. Driver + front passenger + rear passengers +
load in the boot
-. Driver + front passenger + rear passengers +
load in the boot
2. Driver only + maximum authorised load in
the boot
Cornering lighting

If fitted to the vehicle, this system makes use of
the beam from a front foglamp to illuminate the
inside of a bend, when the main or dipped beam
headlamps are on and the vehicle speed is
below 25 mph (40 km/h) (urban driving, winding
road, junctions, parking manoeuvres, etc.).

48
Lighting and visibility
Automatic windscreen wipers
The windscreen wipers operate automatically
once rain is detected (sensor behind the rear
view mirror), adapting their speed to the intensity
of the rain without any action on the part of the
driver.
Switching on

Give a short downwards push to the
control.
A wiping cycle confirms that the instruction has
been accepted.
This warning lamp comes on in the instrument
panel and a message is displayed.
Switching off
Give the control stalk a brief push
downwards or place the control stalk in
another position (Int, 1 or 2).
This warning lamp goes off in the instrument
panel and a message is displayed.
The automatic rain sensitive windscreen wipers must be reactivated by pushing
the control stalk downwards, if the ignition has
been off for more than one minute.
Operating fault
If a fault occurs with the automatic rain sensitive
wipers, the wipers will operate in intermittent
mode.
Have it checked by a CITROËN dealer or a
qualified workshop.
Do not cover the rain sensor, linked with
the sunshine sensor and located at the
top centre of the windscreen, behind the rear
view mirror.
When using an automatic car wash, switch off
the automatic rain sensitive wipers.
In winter, it is advisable to wait until the
windscreen is completely clear of ice before
activating the automatic rain sensitive wipers.

Safety
5In the event of a minor impact or bump at
the side of the vehicle or if the vehicle
rolls over, the airbags may not be deployed.
In the event of a rear or front collision, none of
the lateral airbags are deployed.
Advice
For the airbags to be fully effective,
observe the safety recommendations
below.
Adopt a normal upright sitting position.
Fasten the seat belt ensuring it is correctly
positioned and adjusted.
Do not leave anything between the occupants
and the airbags (a child, pet, object, etc.), nor
fix or attach anything close to or in the way of
the airbag release trajectory; this could cause
injuries during their deployment.
Never modify the original definition of your
vehicle, particularly in the area directly around
the airbags.
After an accident or if the vehicle has been
stolen, have the airbag systems checked.
All work on the airbag systems must only
be performed by a CITROËN dealer or a
qualified workshop.
Even if all of the precautions mentioned
are observed, a risk of injury or of minor
burns to the head, chest or arms cannot be
ruled out when an airbag is deployed. The
airbag inflates almost instantly (within a few
milliseconds) then deflates within the same
time discharging the hot gas via openings
provided for this purpose.
Front airbags
Do not drive holding the steering wheel
by its spokes or resting your hands on the
centre part of the wheel.
Passengers must not place their feet on the
dashboard.
Do not smoke as deployment of the airbags
can cause burns or the risk of injury from a
cigarette or pipe.
Never remove or pierce the steering wheel or
hit it violently.
Do not fix or attach anything to the steering
wheel or dashboard, as this could cause
injuries when the airbags are deployed.
Lateral airbags
Use only approved covers on the seats,
compatible with the deployment of the lateral
airbags. For information on the range of seat
covers suitable for your vehicle, contact a
CITROËN dealer.
Do not fix or attach anything to the seat
backrests (clothes, etc.), as this could cause
injuries to the thorax or arm when the lateral
airbag is deployed.
Do not sit with the upper part of the body any
nearer to the door than necessary.
The vehicle's front door panels include side
impact sensors.
A damaged door or any unauthorised or
incorrectly executed work (modification or
repair) on the front doors or their interior trim
could compromise the operation of these
sensors - risk of malfunction of the lateral
airbags!
Such work must only be done by a CITROËN
dealer or a qualified workshop.
Curtain airbags
Do not fix or attach anything to the roof,
as this could cause head injuries when the
curtain airbag is deployed.
Do not remove the grab handles installed on
the roof, as they play a part in securing the
curtain airbags.
Child seats
The regulations on carrying children are specific to each country. Refer to the
legislation in force in your country.
For maximum safety, please observe the
following recommendations:
–

In accordance with European regulations, all
children under the age of 12 or less than 4
ft 1

1” (150 cm) tall must travel in approved
child seats suited to their weight , on seats
fitted with a seat belt or ISOFIX mountings.

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.
