In the event of detection of a fault with the SCR emissions control system
In the event of detection of a faultDuring an authorised driving phase (between 650 miles and 0 miles) (1 100 km and 0 km)
A system that prevents engine starting is activated automatically 650 miles (1 100 km) after confirmation of a fault with the SCR emissions
control system. Have the system checked by a CITROËN dealer or a qualified workshop as soon as possible.
If it is a temporary fault, the alert
disappears during the next journey,
after a self-diagnostics test of the SCR
emissions control system.
The AdBlue, SERVICE and engine self-
diagnostics warning lamps come on,
accompanied by an audible signal and the
display of the message "Emissions fault".
The alert is triggered when driving, when
the fault is detected for the first time, then
when switching on the ignition for subsequent
journeys, while the fault persists.
If a fault with the SCR system is confirmed (after
30 miles (50 km) covered with the permanent
display of the message signalling a fault), the
SERVICE and engine self-diagnostics warning
lamps come on and the AdBlue warning lamp
flashes, accompanied by an audible signal and
the temporary display in the instrument panel
of "NO START IN" and a distance, indicating
the remaining range expressed in miles or
kilometres before engine starting is prevented
(e.g. "NO START IN 350
miles" means that
starting will be prevented in 350 miles).
While driving, this display appears every 30 seconds
while the fault with the SCR system persists.
The alert is repeated when switching on the
ignition.
You should go to a CITROËN dealer or a
qualified workshop as soon as possible.
Other wise, you will not be able to restart your
engine. Starting prevented
To be able to start the engine, you must call on
a CITROËN dealer or a qualified workshop.
You have exceeded the authorised
driving limit: the starting prevention
system inhibits engine starting.
Every time the ignition is switched on, the
SERVICE and engine self-diagnostics warning
lamps come on and the AdBlue warning lamp
flashes, accompanied by an audible signal and
the temporary display of "NO START IN" and
0 miles or kilometres ("NO START IN 0 miles"
means that starting is prevented).

In order for these systems to be fully effective, follow the operation and maintenance
guidelines below:
F
T
o obtain an even air distribution, take care not to obstruct the exterior air intake grilles
located at the base of the windscreen, the nozzles, the vents and the air outlets, as well
as the air extractor located in the boot.
F

D
o not cover the sunshine sensor, located on the dashboard; this is used for regulation
of the air conditioning system.
F

O
perate the air conditioning system for at least 5 to 10 minutes, once or twice a month
to keep it in per fect working order.
F

E
nsure that the passenger compartment filter is in good condition and have the filter
elements replaced regularly.
W

e recommend the use of a combined passenger compartment filter. Thanks to its
special active additive, it contributes to the purification of the air breathed by the
occupants and the cleanliness of the passenger compartment (reduction of allergic
symptoms, bad odours and greasy deposits).
F

T
o ensure correct operation of the air conditioning system, you are also advised to have
it checked regularly as recommended in the maintenance and warranty guide.
F

I
f the system does not produce cold air, switch it off and contact a CITROËN dealer or a
qualified workshop.
Recommendations for ventilation and air conditioning
If after an extended stop in sunshine,
the interior temperature is very high, first
ventilate 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.
The condensation created by the air
conditioning results in a discharge
of water under the vehicle which is
per fectly normal.
When towing the maximum load on a steep gradient in high temperatures, switching off the
air conditioning increases the available engine power and so improves the towing ability.
Stop & Start
The heating and air conditioning
systems only work when the engine is
running.
To maintain a comfortable temperature
in the passenger compartment, you can
temporarily deactivate the Stop & Start
system.
For more information on Stop & Star t ,
refer to the corresponding section.

When towing
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the axle and the nose weight approaches
the maximum permitted without
exceeding
it.
Air density decreases with altitude, thus
reducing engine per formance. Above
1
000 metres, the maximum towed load must
be reduced by 10
% for every 1 000 metres of
altitude.
For more information on Weights , refer to the
corresponding section.
Side wind
F Take into account the increased sensitivity to side wind.
Cooling
Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towed load on a long incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f the warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam
height of your vehicle.
For more information on Adjusting the
headlamp beam height , refer to the
corresponding section.
The rear parking sensors will be
deactivated automatically to avoid the
audible signal if a genuine CITROËN
towbar is used.
If the exterior temperature is high, it
is recommended that the engine be
allowed to idle for 1 to 2 minutes after
the vehicle comes to a stop, to facilitate
its cooling.

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 only operates when:
-
t
he vehicle is completely stationary, with
your foot on the brake pedal,
-

p
articular conditions on a slope are met,

he driver’s door is closed.
This hill start assist system cannot be
deactivated.
On an ascending slope, with the vehicle
stationary, the vehicle is held momentarily
when you release the brake pedal.On a descending slope, with the vehicle
stationary and reverse gear engaged, the
vehicle is held momentarily when you
release the brake pedal.
Operating fault
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.
Do not leave the vehicle while it is being
held in the hill start assist phase.

to maintain the temperature in the passenger
compartment, it may be useful to deactivate the
Stop & Start system.
The system can be deactivated at any time,
once the ignition is switched on.
If the engine is in STOP mode, it then restarts.
The Stop & Start system is reactivated
automatically every time the ignition is
switched

on.
Deactivation / Reactivation
The Stop & Start system requires
a 12 V battery of specific technology
and specification.
All work on this type of battery must be
carried out only by a CITROËN dealer
or a qualified workshop.
For more information on
the 12 V Battery , refer to the
corresponding section.
Before doing anything under the bonnet,
deactivate the Stop & Start system to
avoid the risk of injury related to an
automatic change to START mode. Opening the bonnet

Misfuel prevention (Diesel)*
When a petrol filler nozzle is introduced into
the fuel filler neck of a Diesel vehicle, it comes
into contact with the flap. The system remains
closed and prevents filling.
Do not persist but introduce a Diesel type
filler nozzle.
* Depending on the country of sale. Mechanical device which prevents filling the tank of a Diesel vehicle with petrol. It avoids the risk of
engine damage that can result from filling with the wrong fuel.It remains possible to use a fuel can to
fill the tank.
In order to ensure a good flow of fuel,
do not place the nozzle of the fuel can
in direct contact with the flap of the
misfuel prevention device and pour
s l ow l y.Travelling abroad
As Diesel fuel pump nozzles may
be different in other countries, the
presence of the misfuel prevention
device may make refuelling impossible.
Not all Diesel vehicles are fitted with
misfuel protection, so before travelling
abroad, we recommend that you check
with the CITROËN dealer network,
whether your vehicle is suitable for the
fuel pumps in the country in which you
intend to travel.

Checking levels
Take care when working under the
bonnet, as certain areas of the engine
may be extremely hot (risk of burns)
and the cooling fan could start at any
time (even with the ignition off).
Engine oil level
The check is carried out either when
the ignition is switched on using the
oil level indicator in the instrument
panel for vehicles so equipped, or
using the dipstick.
Checking using the dipstick
Check all of these levels regularly, in line with the manufacturer's service schedule. Top them up if necessary, unless other wise indicated.
If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.If you find that the level is above the A mark or
below the B mark, do not star t the engine.
-

I
f the level is above the MAX mark (risk
of damage to the engine), contact a
CITROËN dealer or a qualified workshop.
-

I
f the level is below the MIN mark, you
must top up the engine oil.
A = MA X
B = MIN
To ensure that the reading is correct,
your vehicle must be parked on a level
sur face with the engine having been off
for more than 30 minutes.
It is normal to top up the oil level between
two services (or oil changes). CITROËN
recommends that you check the level, and top
up if necessary, every 3 000 miles (5 000 kms). The location of the dipstick is shown in the
corresponding underbonnet layout view.
