The system is reactivated automatically
at every new start using the START/
STOP button.
Reactivation
Press the "ECO OFF"
switch again.
The system is active again; this is confirmed
by the switch warning lamp going off and a
message in the screen.
Operating fault
In the event of a fault with the system, the
"ECO OFF"
switch warning lamp flashes then
comes on continuously.
Have it checked by a CITROËN dealer or a
qualified workshop.
In the event of a fault in STOP mode, the vehicle
may stall.
All of the instrument panel warning lamps come
on.
Depending on version, an alert message may also
be displayed, asking you to place the gear lever in
position N
and put your foot on the brake pedal.
It is then necessary to switch off the ignition and
start the engine again using the "START/STOP"
button.
Before doing anything under the
bonnet, deactivate the Stop & Start
system to avoid any risk of injury
resulting from automatic operation of
START mode.
This system requires a 12 V battery with a
special specification and technology (reference
numbers available from CITROËN dealers).
Fitting a battery not listed by CITROËN
introduces the risk of malfunction of the
system.
For charging, use a 12 V charger and do not
reverse the polarity.
Maintenance
The Stop & Start system makes use of
advanced technology. For any work on
the system go to a qualified workshop
with the skills and equipment required,
which a CITROËN dealer is able to
provide.

Dynamic stability control (DSC)
and anti-slip regulation (ASR)
Activation
These systems are activated automatically
each time the vehicle is started.
As soon as they detect a problem of grip or
trajectory, these systems act on the operation if
the engine and brakes.
This is indicated by flashing of this
warning lamp in the instrument panel.
Deactivation
Operating fault
Illumination of this warning lamp and
the lamp in the deactivation button,
accompanied by an audible signal
and a message, indicate a fault with
the system.
Reactivation
Press this button.
The indicator lamp in the button comes on.
The DSC and ASR systems no longer act on the
operation of the engine and on the brakes in the
event of a involuntary change of trajectory.
Press this button again.
Reactivate the systems as soon as the level of
grip permits.
Contact a CITROËN dealer or a qualified
workshop to have the system checked. In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground...), it may be advisable to deactivate
the DSC and ASR, so that the wheels can turn
freely and regain grip. The systems are reactivated automatically each
time the ignition is switched back on or from
30 mph (50 km/h).
Below 30 mph (50 km/h), you can reactivate
them manually:

additive is liquid again.
The emissions warning lamp does not go off immediately and will
occur after several mile of running.
You have 680 miles (1100 km) to contact a franchised dealer or a qualified
workshop to have the injection system adjusted. the alert will be repeated
every 62 miles (100 km).
After the 680 miles (1100 km) you will not be able to start the engine until it
has been checked.

3Practical information
AdBlue ® additive and SCR system
for Blue HDi 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 emissions filter (PEF) for the treatment of exhaust gases.
Presentation of the SCR system
Using an additive called AdBlue ® containing urea, ® 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.
The AdBlue ® additive is held in a special ® additive is held in a special ®
tank located under the boot at the rear of the vehicle. It has a capacity of 17 litres: this provides a driving range of about 12 500 miles
(20 000 km), after which an alert is triggered warning you when the reserve remaining is enough for just 1 500 miles (2 400 km).
During each scheduled service of your vehicle by a CITROËN dealer or a qualified workshop, the AdBlue ® additive tank is refilled in order to ® additive tank is refilled in order to ®
allow normal operation of the SCR system.
If the estimated mileage between two services is greater than 12 500 miles (20 000 km), we recommend that you go to a dealer to have the necessary top-up carried out.
Once the AdBlue ® tank is empty, ® tank is empty, ®
a system required by regulations prevents starting of the engine.
If the SCR is faulty, the level of emissions from your vehicle will longer meet the Euro 6 standard: you 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.

Range indicators
When switching on the ignition, an indicator gives an estimate of the distance that can be travelled with your vehicle before engine starting is automatically prevented, once the vehicle starts using the reserve of AdBlue ® or ® or ®
after a fault is detected with the SCR system. In the event of simultaneous system fault and low AdBlue ® level, the shortest range is ® level, the shortest range is ®
the one displayed.
In the event of the risk of non-starting related to a lack of AdBlue ® In the event of the risk of non-starting related to a lack of AdBlue ® In the event of the risk of non-starting related to a lack of AdBlue
The engine start prevention system required by regulations is activated automatically once the AdBlue ® tank ® tank ®
is empty.
Range greater than 1 500 miles (2 400 km) When the ignition is switched on, no information on range is displayed automatically in the instrument panel.
Pressing this button displays the driving range temporarily. Above 3 000 miles (5 000 km), the value is not specified.

If it is a temporary fault, the alert disappears once the exhaust gas emissions return to normal.
A system that prevents engine starting is activated automatically from 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.
When switching on the ignition, the UREA, SERVICE and diagnostic warning lamps comes on, accompanied by an audible signal and the display of a message "Emissions fault" to signal a fault with the emissions control system.
In the event of the detection of a fault
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), when switching on the ignition, the SERVICE and engine diagnostic warning lamps come on and the UREA warning lamp flashes,
accompanied by an audible signal and the display of a message (e.g.: "Emissions fault: Starting prevented in 150 miles") indicating the remaining range express in miles or kilometres. While driving, the message is displayed every 30 seconds while the fault with the SCR system persists. You should go to a CITROËN dealer or a qualified workshop as soon as possible. If you fail to do this, there is a risk that you will not be able to start your engine.
During an authorised driving phase (between 650 miles and 0 miles) (1 100 km and 0 km)

7Practical information
Every time the ignition is switched on, the SERVICE and engine diagnostic warning lamps come on and the UREA warning lamp flashes, accompanied by an audible signal and the display of the message "Emissions fault: Starting prevented".
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.
Freezing of the AdBlue ® Freezing of the AdBlue ® Freezing of the AdBlue additive
The AdBlue ® additive freezes at ® additive freezes at ®
temperatures below around -11°C. The SCR system includes a heater for the AdBlue ® tank. ® tank. ®
In exceptional circumstances (vehicle kept for a long period at temperatures that are constantly below -15°C), an emissions control system fault alert may be related to freezing of the AdBlue ® in your vehicle. ® in your vehicle. ®
Park your vehicle in a warmer area for a few hours until the additive becomes liquid again. The emissions alert does not go off immediately, it will occur after several mile of running.
