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.

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

Driving
Stop & Start
The Stop & Start function puts the engine temporarily into standby - STOP mode - during
phases when the vehicle is stopped (red lights,
queues, etc.). The engine restarts automatically
- START mode - as soon as the driver wishes to
move off again.
Primarily designed for urban use, the function
is intended to reduce fuel consumption and
exhaust emissions as well as the noise level
when stationary.
The function does not affect the functionalities of
the vehicle, in particular the braking.
Deactivation/Reactivation
The function is activated by default when the
ignition is switched on.
It is set via the Driving / Vehicle touch
screen menu.
A message in the instrument panel confirms the
change of status.
When the function is deactivated, if the engine
was in standby, it restarts immediately.
Associated indicator lamp
Function activated.
Opening the bonnet
Before doing anything under the bonnet,
deactivate the Stop & Start system to avoid
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one or
more tyres.
Under-inflation detection does not
replace the need for vigilance on the part
of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel) as well as before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high
speed, long journey):
–

worsens road-holding.
–


lengthens braking distances.
–


causes premature wear of the tyres.
–


increases fuel consumption.
The inflation pressures defined for the vehicle can be found on the tyre pressure
label.
For more information on the Identification
markings, refer to the corresponding section.
Checking tyre pressures
This check should be done when the
tyres are "cold" (vehicle stopped for 1 hour or
after a journey of less than 6 miles (10
km) at
moderate speeds).
Otherwise, add 0.3 bar to the pressures
shown on the label.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Spare wheel
The steel spare wheel does not have an
under-inflation detection sensor.
Under-inflation alert
This is signalled by the fixed illumination of this warning lamp, accompanied by an
audible signal and the display of a message.
►

Reduce speed immediately
, avoid excessive
steering movements and avoid sudden braking.
►

Stop the vehicle as soon as it is safe to do
so.
The loss of pressure detected does not always cause visible bulging of the tyre.
Do not rely on just a visual check.
►

Using a compressor
, such as the one in
the temporary puncture repair kit, check the
pressures of the four tyres when cold.
►

If it is not possible to make this check
immediately

, drive carefully at reduced speed.
►

In the event of a puncture, use the
temporary puncture repair kit or the spare wheel
(depending on equipment).
The alert is kept active until the system is reinitialised.
Reinitialisation
Reinitialise the system after adjusting one or
more tyre pressures and after changing one or
more wheels.


Before reinitialising the system, make
sure that the pressures of the four tyres
are correct for the conditions of use of the
vehicle and conform to the values written on
the tyre pressure label.
Check the pressures of the four tyres before
performing the reinitialisation.
The system does not advise if a pressure is
incorrect at the time of reinitialisation.
With the vehicle stationary, the system is
reinitialised via the Driving /
V
ehicle touch screen menu.
Malfunction
These warning lamps come on in the event of a malfunction.
In this case, the tyre under-inflation monitoring
function is no longer performed.
Have the system checked by a CITROËN dealer
or a qualified workshop.
