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
on, an indicator displays an estimate of the
distance that can be covered, the range, before
engine starting is prevented.
In the event of simultaneous system fault and
low AdBlue
® level, the shortest range figure is
the one displayed.
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 is
e m pt y.
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.
For more information on topping-
up the AdBlue® additive, refer to the
corresponding section.

Remaining range between 350 and 1500 miles (600 and 2 400 km)
When switching on the ignition, the
UREA warning lamp comes on, accompanied
by an audible signal and the display of a
message (e.g.: "Top up emissions additive:
Starting prevented in 900 miles") indicating
the remaining range expressed in miles or
kilometres.
When driving, the message is displayed every
200 miles (300 km) until the additive tank has
been topped-up.
Go to a CITROËN dealer or a qualified
workshop to have the AdBlue
® tank topped-up.
You can also top-up the tank yourself.
For more information on topping-up the
AdBlue
® additive, refer to the corresponding
section.
Remaining range between 0 and 350 miles (0 and 600 km)
When switching on the ignition, the SERVICE
warning lamp comes on and the UREA warning
lamp flashes, accompanied by an audible
signal and the display of a message (e.g.
"Top up emissions additive: Starting prevented
in 350 miles") indicating the remaining range
expressed in miles or kilometres.
When driving, the message is displayed every
30 seconds until the additive tank has been
topped-up.
Go to a CITROËN dealer or a qualified
workshop to have the AdBlue
® tank topped-up.
You can also top-up the tank yourself.
Other wise you will not be able to restart your
engine. When switching on the ignition, the SERVICE
warning lamp comes on and the UREA warning
lamp flashes, accompanied by an audible
signal and the display of the message "Top up
emissions additive: Starting prevented".
The AdBlue
® tank is empty: the system required
by regulations prevents engine starting.
Breakdown related to a lack of AdBlue® additive
To be able to start the engine,
we recommend that you call on
a CITROËN dealer or a qualified
workshop for the top-up required.
If you carry out the top-up yourself, it
is essential to add at least 3.8 litres of
AdBlue
® to the tank.

In the event of a fault with the SCR emissions control system
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.You have exceeded the authorised
driving limit: the starting prevention
system inhibits engine starting.
If it is a temporary fault, the alert
disappears during the next journey,
after self-diagnosis of the SCR system.
The UREA, SERVICE and diagnostic warning
lamps comes 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. 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), 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.
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.
During an authorised driving phase (between
650 miles and 0 miles) (1 100 km and 0 km)
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.

AdBlue
® tank is completely empty -
w
hich is confirmed by the alert
messages and the impossibility of
starting the engine, you must add at

lever, then the exterior safety catch,
F

s
ecure the bonnet stay,
F

l
ift the plastic cover on the (+) terminal. First check that the slave battery has a
nominal voltage of 12 V and a capacity
at least equal to that of the discharged
battery.
Do not try to start the engine by
connecting a battery charger.
Do not disconnect the (+) terminal when
the engine is running.
F

C
onnect the red cable to the positive
terminal (+) of the flat battery A , then to the
positive terminal (+) of the slave battery B.

onnect one end of the green or black
cable to the negative terminal (-) of the
slave battery B (or earth point on the other
vehicle).
F

C
onnect the other end of the green or black
cable to the negative terminal C
(or the engine mounting) of the broken-
down vehicle.
F

S
tart the engine of the other vehicle and
allow it to run for a few minutes.
Starting using another
battery
When the battery on your vehicle is discharged,
the engine can be started using a slave battery
(external or on another vehicle) and jump leads.
F

O
perate the starter of the broken-down
vehicle and let the engine run.
I

f the engine does not start immediately,
switch off the ignition and wait a few
moments before trying again.
F

W
ait until the engine returns to idle, then

Practical information

185
Charging the battery using
a battery charger
F Follow the instructions for use provided by the manufacturer of the charger. Protect your eyes and face before
handling the battery.
All operations on the battery must be
carried out in a well ventilated area
away from naked flames and sources
of sparks, so as to avoid the risk of
explosion and fire.
Do not try to charge a frozen battery;
the battery must first be thawed out to
avoid the risk of explosion. If the battery
has been frozen, before charging have
it checked by a CITROËN dealer or a
qualified workshop who will check that
the internal components have not been
damaged and the casing is not cracked,
which could cause a leak of toxic and
corrosive acid.
Do not reverse the polarity and use only
a 12 V charger.
Do not disconnect the terminals while
the engine is running.
Do not charge the batteries without
disconnecting the terminals first.
Wash your hands after wards.
Batteries contain harmful substances such
as sulphuric acid and lead. They must be
disposed of in accordance with regulations
and must not, in any circumstances, be
discarded with household waste.
Take used remote control batteries and
vehicle batteries to a special collection
point.
