Engine oil level
indicator
(depending on version)
On versions fitted with an electric oil level

displayed in the instrument panel for a few
seconds, after the servicing information.
The level read will only be correct if the
vehicle is on level ground and the engine
has been off for more than 30 minutes.
Oil level correct
This is indicated by the display of the " Oil level
correct " message.
Oil level insufficient
If the low oil level is confirmed by a check using
the dipstick, the level must be topped up to avoid
damage to the engine.
For more information on Checking levels, refer
to the corresponding section.
Oil level indicator fault
This is signalled by the display of the " Oil
level measurement invalid" message on the
instrument cluster.
Contact a CITROËN dealer or a qualified
workshop.
In the event of a fault with the electric
indicator, the oil level is no longer
monitored.
If the system is faulty, you must check the
engine oil level using the manual dipstick
located under the bonnet.
For more information on Checking levels,
refer to the corresponding section.
AdBlue® range indicators
(BlueHDi)
The Diesel BlueHDi engines are equipped with
a system that associates the SCR (Selective
Catalytic Reduction) emissions control system
and the Diesel particle filter (DPF) for the
treatment of exhaust gases. They cannot
function without AdBlue
® fluid.
When the level of AdBlue® falls below the
reserve level (between 1,500 and 0 miles (2,400
and 0 km)), a warning lamp lights up when the ignition is switched on and an estimate
of the distance that can be travelled before
engine starting is prevented is displayed in the
instrument panel.
The engine starting prevention system required by regulations is activated
automatically once the AdBlue
® tank is empty.
It is then no longer possible to start the
engine until the minimum level of AdBlue
® has
been topped up.
Manually displaying the driving range
While the driving range is greater than 1,500 miles (2,400 km), it is not displayed automatically.

CHECK

► Press this button to temporarily display the driving range.You can view the range information by pressing the " Diagnostic" button after selecting the " Driving functions " tab in the

Malfunction of the
SCR emissions
control system
Malfunction detection


If a malfunction is detected,
these warning lamps come on,
accompanied by an audible
signal and an "Emissions fault”
message.
The alert is triggered while driving, when the
fault is detected for the first time, and thereafter
when switching on the ignition for subsequent
journeys, while the cause of the fault persists.
If the fault is temporary, the alert
disappears during the next journey, after
self-diagnostic checks of the SCR emissions
control system.
Malfunction confirmed during the
permitted driving phase (between 685
miles and 0 miles (1,100 km and 0 km))
If the fault indication is still displayed permanently after 31 miles (50 km) of driving, the fault in the SCR system is confirmed.
The AdBlue warning lamp flashes, and an
"Emissions fault: Starting prevented in X
miles" or "NO START IN X miles" message is
displayed, indicating the driving range in miles or
kilometres.
While driving, the message is displayed every 30
seconds. The alert is repeated when switching
on the ignition.
You can continue driving for up to 685 miles
(1,100 km) before the engine immobiliser
system is triggered.
Have the system checked by a
CITROËN dealer or a qualified workshop
as soon as possible.
Starting prevented
Whenever the ignition is switched on, the
"Emissions fault: Starting prevented" or "NO
START IN" message is displayed.

Automatic illumination of
headlamps
When the ring is at the "AUTO" position and
a low level of ambient light is detected by a
sunshine sensor, the number plate lamps, side lamps and dipped beam headlamps are switched
on automatically, without any action on the
part of the driver. They can also come on if
rain is detected, at the same time as automatic
operation of the windscreen wipers.
As soon as the light returns to a sufficient level
or after the windscreen wipers are switched off,
the lamps are switched off automatically.
