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 miles 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.
Manual display of the range
While the driving range is greater than
1,500 miles (2,400 km), it is not displayed
automatically.
You can view the range information by pressing the " Diagnostic" button
in the
touch screen’s 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
level corresponding to a range of 1,500 miles
(2,400
km).
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.

topping up, refer to the corresponding section.

Lighting and visibility
4Switching off of the lamps when the
ignition is switched off
When the ignition is switched off, all of the
lamps turn off immediately, except for dipped
beam headlamps if automatic guide-me-home
lighting is activated.
Switching on the lighting after
switching off the ignition
To reactivate the lighting control, rotate the
ring to the "0" position - lights off, then to the
desired position.
When the driver's door is opened, a
temporary audible signal warns you that the
vehicle's lighting is on.
The lighting, with the exception of the
side lights, switch off automatically after a
maximum duration of thirty minutes to prevent
discharging of the battery.
In some weather conditions (e.g. low
temperature or humidity), misting on the
internal surface of the glass of the headlamps
and rear lamps is normal, and will disappear
after the lamps have been on for a few
minutes.
Travelling abroad
Vehicles equipped with halogen
headlamps:
If planning to use your vehicle in a country
that drives on the other side of the road, the
headlamp dipped beams must be adjusted to
avoid dazzling oncoming drivers. Contact a
CITROËN dealer or a qualified workshop.
Direction indicators

► Left: lower the lighting control stalk beyond
the point of resistance.
►

Right: raise the lighting control stalk beyond
the point of resistance.
Three flashes
► Press briefly upwards or downwards, without
going beyond the point of resistance; the
direction indicators will flash 3 times.
Parking lamps
Vehicle side marking by lighting the sidelamps
on the traffic side only.
►

Depending on version, within one minute
of switching off the ignition, move the lighting control stalk up or down, depending which side
the traffic is on (for example, when parking on
the left, moving the lighting control stalk upwards
turns on the right-hand sidelamps).
This is confirmed by an audible signal and the
lighting of the corresponding direction indicator
lamp on the instrument panel.
►


T
o switch off the parking lamps, return the
lighting control stalk to the central position.
Automatic illumination of headlamps
When the ring is at the “AUTO" position and
a low level of ambient light is detected by the
rain/sunshine sensor, the number plate lamps,
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
sunshine sensor, the lamps come on, this
warning lamp is displayed on the instrument
panel together with an audible signal and/or a
message.
