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.

Settings>Vehicle touch screen application.
Engine oil level indicator
(Depending on version)
On versions fitted with an electric gauge, the
engine oil level status is displayed on the
instrument panel for a few seconds when
the ignition is switched on, after the servicing
information, in the form of messages.
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.
Low oil level
This is indicated by the message " Oil
level incorrect" on the instrument panel,
accompanied by the lighting of the Service
warning lamp and an audible signal.
If a 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 gauge malfunction
This is indicated by the message " Oil level
measurement invalid" on the instrument panel.
Contact a CITROËN dealer or a qualified
workshop.

19
Instruments
1In the event of a malfunction of the
electric gauge, the oil level is no longer
monitored.
If the system is faulty, you must check the
engine oil level using the manual dipstick
located in the engine compartment.
For more information on Checking levels,
refer to the corresponding section.
Coolant temperature
indicator
This information is only available in the
instrument panel's customisable area.
For more information on the Digital instrument
panel, refer to the corresponding section.


With the engine running:

For more information on Checking
levels, refer to the corresponding
section.
Power indicator
(Rechargeable hybrid)
The power indicator shows in real time the power
demanded from the vehicle.
There are 3 zones:


POWER High power demand, using the combined capabilities of the petrol
engine and the electric motor.
The slider is located in this zone
during more dynamic driving phases
when high levels of performance are
being demanded.
ECO Optimal use of energy (internal combustion or electric).
The slider is located in this zone
when driving under electric power
and when optimal use is being made
of the petrol engine, both accessible
by adopting a suitable driving style.
A symbol indicates the threshold at
which the petrol engine will restart.
The driver can therefore moderate
their acceleration to remain in electric
driving mode.
CHARGE Energy recovery for partly recharging the traction battery.
The slider is located in this zone
during deceleration: taking your foot
off the accelerator pedal or braking.
Partial recharging of the battery by
energy recovery has no effect on the
charge level indicator.
Charge level indicator
(Rechargeable hybrid)


The charge level of the traction battery and
the remaining range in electric driving mode
are permanently displayed when the vehicle is
switched on.

►

Rotate the ring backwards to switch the
foglamps off; the sidelamps will then switch off.
Switching on the foglamps is prohibited
in clear weather or in rain, both day and

only be used in fog or falling snow (rules may
vary depending on country).
Do not forget to switch off the foglamps when
they are no longer necessary.

Automatic illumination of
lamps
With the lighting control stalk in the “ AUTO”
position and if a low level of exterior brightness
is detected by the rain/sunshine sensor, the
sidelamps and dipped beam headlamps are
switched on automatically, without any action on
the part of the driver. They may also come on if
rain is detected, at the same time as automatic
operation of the windscreen wipers.
As soon as the brightness returns to a sufficient
level or after the windscreen wipers are switched
off, the lamps are switched off automatically.
Malfunction
In the event of a malfunction of the rain/
sunshine sensor, the vehicle’s lamps
come on and this warning lamp is displayed on
the instrument panel, accompanied by an
audible signal and/or the display of a message.
Have it checked by a CITROËN dealer or a
qualified workshop.
Do not cover the rain/sunshine sensor
located at the top centre of the
windscreen behind the interior rear view
mirror; the associated functions would no
longer be controlled.
In fog or snow, the rain/sunshine sensor
may detect sufficient light. For this
reason, the lighting will not come on
automatically.
The inner surface of the windscreen may become misted up and affect the proper
operation of the rain/sunshine sensor.
In humid and cold weather, demist the
windscreen regularly.

come on on the instrument panel.
The function is deactivated if the foglamps
are switched on or if the system detects poor
visibility conditions (e.g.
fog, heavy rain,
snowfall).
When the foglamps are switched off or when the
visibility conditions become favourable again, the
function is automatically reactivated.
This indicator lamp goes out when the function is deactivated.
If the function is selected but the display

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, junctions, parking
manoeuvres).
