Misfuel prevention (Diesel)*  
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.  
Located in the filler neck, the misfuel prevention device appears when the filler cap is removed.  
Operation  
It remains possible to use a fuel can to  
fill the tank.  
Travelling abroad  
As Diesel fuel pump nozzles may  
be different in other countries, the  
presence of the misfuel prevention  
device may make refuelling impossible.  
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 want to travel.  
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  
slowly.  
When a petrol filler nozzle is introduced into the  
fuel filler neck of your Diesel vehicle, it comes  
into contact with the flap. The system remains  
closed and prevents filling.

Depending on the environment (e.g. dusty  
atmosphere) and the use of the vehicle  
(e.g. city driving), replace them twice as often  
if necessary.  
A clogged passenger compartment filter may  
have an adverse effect on the performance  
of the air conditioning system and generate  
undesirable odours.  
As soon as the traffic conditions permit,  
regenerate the filter by driving at a  
speed of at least 40 mph (60 km/h) until  
the warning lamp goes off.  
If the warning lamp stays on, this  
indicates a low additive level.  
Electronic gearbox

interval for this component.  
On a new vehicle, the first particle  
filter regeneration operations may be  
accompanied by a "burning" smell,  
which is perfectly normal.  
Following prolonged operation of the  
vehicle at very low speed or at idle,  
you may, in exceptional circumstances,  
notice the emission of water vapour at  
the exhaust on acceleration. This does  
not affect the behaviour of the vehicle  
or the environment.  
Oil filter  
Replace the oil filter each time the  
engine oil is changed.

Brake pads  
Electric parking brake  
Brake wear depends on the style  
of driving, particularly in the case  
of vehicles used in town, over short  
distances. It may be necessary to  
have the condition of the brakes checked, even  
between vehicle services.  
Unless there is a leak in the circuit, a drop in  
the brake fluid level indicates that the brake  
pads are worn.  
This system does not require any  
routine servicing. However, in the  
event of a problem, have the system  
checked by a CITROËN dealer or a  
qualified workshop.  
Only use products recommended by  
CITROËN or products of equivalent  
quality and specification.  
In order to optimise the operation of  
units as important as those in the  
braking system, CITROËN selects and  
offers very specific products.  
For more information, refer to the "Electric  
parking brake - Operating faults" section.  
After washing the vehicle, dampness,  
or in wintry conditions, ice can form  
on the brake discs and pads: braking  
efficiency may be reduced. Make light  
brake applications to dry and defrost  
the brakes.  
Brake disc wear  
For information on checking brake  
disc wear, contact a CITROËN dealer  
or a qualified workshop.

Checks  
AdBlue® additive and SCR system  
for BlueHDi Diesel engines  
To assure respect for the environment and  
conformity with the new Euro 6 emissions  
standard, without adversely affecting the  
performance or fuel consumption of Diesel  
engines, CITROËN has taken the decision to  
equip its vehicles with an effective system that  
associates SCR (Selective Catalytic Reduction)  
with a particle filter (FAP) for the treatment of  
exhaust gases.

In the event of a confirmed fault  
with the SCR system, you must go  
to a CITROËN dealer or a qualified  
workshop as soon as possible: after  
a running distance of 650 miles  
(1 100 km), a system will be triggered  
automatically to prevent engine  
starting.  
During each scheduled service of your vehicle  
by a CITROËN dealer or a qualified workshop,  
the AdBlue® additive tank is refilled in order to  
allow normal operation of the SCR system.  
Presentation of the ScR system  
Using an additive called AdBlue® containing urea,  
a catalytic converter turns up to 85% of nitrous  
oxides (NOx) into nitrogen and water, which are  
harmless to health and the environment.  
If the estimated mileage between two services  
is greater than 12 500 miles (20 000 km), we  
recommend that you go to a CITROËN dealer  
or a qualified workshop to have the necessary  
top-up carried out.  
Range indicators  
Once the AdBlue® tank is on reserve or after  
detection of a fault with the SCR emissions  
control system, when the ignition is switched

Use only AdBlue® additive that meets the  
ISO 22241 standard.  
Precautions in use  
included in every routine service on your  
vehicle by a CITROËN dealer or a qualified  
workshop.  
Nevertheless, given the capacity of the tank,  
it may be necessary to top-up the additive  
between services, more particularly if an alert  
(warning lamps and a message) signals the  
requirement.  
You can got to a CITROËN dealer or a qualified  
workshop.  
If you envisage topping-up yourself, please  
read the following warnings carefully.  
The AdBlue® additive is an urea-based  
solution. This liquid is non-flammable,  
colourless and odourless (kept in a cool area).  
In the event of contact with the skin, wash  
the affected area with soap and water. In the  
event of contact with the eyes, wash (irrigate)  
the eyes with large amounts of water or with  
an eye wash solution for at least 15 minutes.  
If a burning sensation or irritation persists, get  
medical attention.  
Never dilute the additive with water.  
Never pour the additive into the Diesel  
fuel tank.  
If swallowed, immediately wash out the mouth  
with clean water and then drink plenty of water.  
In certain conditions (high ambient  
temperature, for example), the risk of release  
of ammonia cannot be excluded: do not inhale  
the product. Ammonia vapour has en irritant  
effect on mucous membranes (eyes, nose and  
throat).  
The supply in a non-drip bottle simplifies  
toping-up. You can obtain 1.89 litre (half a US  
gallon) bottles from a CITROËN dealer or a  
qualified workshop.  
Keep AdBlue® out of the reach of  
children, in its original bottle.

Recommendations on storage  
Procedure  
AdBlue® freezes at about -11°C and  
deteriorates above 25°C. It is recommended  
that bottles be stored in a cool area and  
protected from direct sunlight.  
Under these conditions, the additive can be  
kept for at least a year.  
Before topping-up, ensure that the vehicle is  
parked on a flat and level surface.  
In wintry conditions, ensure that the  
temperature of the vehicle is above -11°C.  
Otherwise, by freezing, the AdBlue® cannot  
be poured into its tank. Park your vehicle in a  
warmer area for a few hours to allow the top-up  
to be carried out.  
If the additive has frozen, it can be used once it  
has completely thawed out.
