Limit the causes of excess consumption
Spread loads throughout the vehicle; place the heaviest items in the
bottom of the boot, as close as possible to the rear seats.
Limit the loads carried in the vehicle and reduce wind resistance (roof
bars, roof rack, bicycle carrier, trailer...). Use a roof box in preference.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and refit your summer tyres.
Observe the recommendations on
maintenance
Check the tyre pressures regularly, when cold, referring to the label in
the door aperture, driver's side.
Carry out this check in particular:
-
b
efore a long journey,
-

a
t each change of season,
-

a
fter a long period out of use.
Don't forget the spare wheel and the tyres on any trailer or caravan.
Have your vehicle serviced regularly (engine oil, oil filter, air filter,
passenger compartment filter...) and observe the schedule of
operations recommended in the manufacturer's service schedule.
With a BlueHDi Diesel engine, if the SCR system is faulty your vehicle
becomes polluting; go to a CITROËN dealer or a qualified workshop
without delay to have the emissions of nitrogen oxides brought back to
the legal level.
When refuelling, do not continue after the third cut-off of the nozzle to
avoid any over flow.
At the wheel of your new vehicle, it is only after the first 1 800 miles
(3
000 kilometres) that you will see the fuel consumption settle down to
a consistent average.

AdBlue® range indicators
These range indicators are present only on
BlueHDi Diesel versions.
Once the AdBlue
® tank is on reserve or after
detection of a fault with the SCR emissions
control system, when the ignition is switched
on, an indicator displays an estimate of the
distance that can be covered, the range, before
engine starting is prevented. Pressing this button will temporarily
display the remaining range with the
message "AdBlue: range greater than
1 500 miles" and, depending on the
level in the AdBlue tank, followed by
a message indicating that you can
top up with at least 10 litres.
The engine start prevention system
required by regulations is activated
automatically once the AdBlue
® tank is

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).

AdBlue® 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
per formance 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.
SCR system
Using a fluid called AdBlue® containing urea, a
catalytic converter turns up to 85% of nitrogen
oxides (NOx) into nitrogen and water, which are
harmless to health and the environment. Once the AdBlue
® tank is empty, a
s
ystem required by regulations prevents
starting of the engine.
If the SCR

system is faulty, the level
of emissions from your vehicle will no
longer meet the Euro 6 standard: your
vehicle becomes polluting.
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.
In either case, a range indicator gives
you the distance you can travel before
the vehicle is immobilised.
The AdBlue® is held in a special tank with
a capacity of about 15 litres: this provides
a driving range of about 11 000 miles
(18

000

km). An alert is triggered automatically
to warn you when the reserve level is
reached: you can then drive about 1 500 miles
(2

400

km) before the tank is empty.
Freezing of the AdBlue
®
AdBlue® freezes at temperatures below
around -11°C.
The SCR system includes a heater
for the AdBlue
® tank, allowing you
to continue driving in all weather
conditions.
