Service indicator
The servicing information is expressed in terms
of distance (kilometres or miles) and time
(months or days).
The alert is given at whichever of these two
terms is reached first.
The servicing information is displayed in the
instrument panel. Depending on the version of
the vehicle:
– The distance recorder display line indicates the distance remaining before the next service
is due, or the distance travelled since it was due
preceded by the "-" sign.
– An alert message indicates the distance remaining, as well as the period before the next
service is due or how long it is overdue.
The value indicated is calculated according to the distance covered and
the time elapsed since the last service.
The alert may also be triggered close to a
due date.
Service spannerOn temporarily when the ignition is switched on.
Between 620 and 1,860 miles (1,000 and 3,000
km) remain before the next service is due.

Together with the warning lamps, messages
regularly remind you of the need to top up to
avoid engine starting being prevented. Refer to
the Warning and indicator lamps section for
details of the messages displayed.
For more information on AdBlue®
(BlueHDi engines), and in particular on

Engine oil level
indicator
(depending on version)
On versions fitted with an electric oil level
indicator, the state of the engine oil level is
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
Driving / Vehicle menu.
Actions required related to a lack of AdBlue®
The following warning lamps light up when the
quantity of AdBlue® is lower than the reserve

and Starting” system.
When the monitoring system is active, the
indicator lamp in the button flashes once per
second and the direction indicators come on for
about 2 seconds.
The exterior perimeter monitoring is activated
after 5 seconds and the interior volumetric and
anti-tilt monitoring after 45 seconds.
If an opening (door, boot, bonnet, etc.) is
incorrectly closed, the vehicle is not

will be activated after 45 seconds, at the
same time as the interior volumetric and
anti-tilt monitoring.
Deactivation

is not opened within 30 seconds of
unlocking), the monitoring system is
automatically reactivated.
Locking the vehicle
with exterior perimeter
monitoring only
Disable volumetric monitoring to avoid unwanted
alarm triggering in certain cases, such as:
– Slightly open window .– Washing the vehicle.– Changing a wheel.– Towing your vehicle.– Transport on a ship or ferry.
Deactivating the interior volumetric
and anti-tilt monitoring
► Switch off the ignition and within 10 seconds, press this button until the
indicator lamp is on continuously.
► Get out of the vehicle.► Lock the vehicle immediately using the remote control or the "Keyless Entry and
Starting" system.

Lighting and visibility
4• If the "AUTO" and "Main beam" indicator lamps were on, the system changes to dipped beam.
To reactivate the system, flash the headlamps
again.
The system may be disrupted or not work correctly:
– When visibility conditions are poor (snowfall, heavy rain, etc.).– If the windscreen in front of the camera is dirty, misted or obscured (for example, by a
sticker).
– If the vehicle is facing highly reflective signs.
When the system detects thick fog, it
temporarily deactivates the function.
The system is not able to detect:
– Road users that do not have their own lighting, such as pedestrians.– Vehicles whose lighting is obscured (for example, vehicles driving behind a safety
barrier on a motorway).
– Vehicles at the top or bottom of a steep slope, on winding roads, on crossroads.
Clean the windscreen regularly,
particularly the area in front of the
camera.
The internal surface of the windscreen can
also become misted around the camera.
In humid and cold weather, demist the
windscreen regularly.
Do not allow snow to accumulate on the
bonnet or roof of the vehicle as this could
obstruct the detection camera.
Headlamp beam height
adjustment



To avoid causing a nuisance to other road users,
the height of the headlamp beams should be
adjusted according to the load in the vehicle.
0. (Initial adjustment)
Driver only or driver + front passenger
1. Driver + front passenger + rear passengers +
maximum authorised load
2. Driver only + maximum authorised load
Cornering lighting

If your vehicle is so equipped, this system
makes use of the beam from a front foglamp to
illuminate the inside of a bend, when the main or
dipped beam headlamps are on and the vehicle
speed is below 25 mph (40 km/h) (urban driving,
winding road, intersections, parking manoeuvres,
etc.).
