Limit the causes of excess consumption
Spread loads throughout the vehicle; place the heaviest items in the
bottom of the boot, as close as possible to the rear seats.
Limit the loads carried in the vehicle and reduce wind resistance (roof
bars, roof rack, bicycle carrier, trailer...). Use a roof box in preference.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and refit your summer tyres.
Observe the recommendations on
maintenance
Check the tyre pressures regularly, when cold, referring to the label in
the door aperture, driver's side.
Carry out this check in particular:
-
be
fore a long journey,
-
at e
ach change of season,
-
af
ter a long period out of use.
Don't forget the spare wheel and the tyres on any trailer or caravan.
Have your vehicle serviced regularly (engine oil, oil filter, air filter,
passenger compartment filter...) and observe the schedule of
operations recommended in the manufacturer's service schedule.
With a BlueHDi Diesel engine, if the SCR system is faulty your vehicle
becomes polluting ; go to a CITROËN dealer or a qualified workshop
without delay to have the emissions of nitrous oxides brought back to
the legal level.
When refuelling, do not continue after the third cut-off of the nozzle to
avoid any over flow.
At the wheel of your new vehicle, it is only after the first 1 800 miles
(3
0
00 kilometres) that you will see the fuel consumption settle down to
a consistent average.

It remains possible to use a fuel can to
fill the tank.
In order to ensure a good flow of fuel,
do not place the nozzle of the fuel can
in direct contact with the flap of the
misfuel prevention device and pour

Misfuel prevention (Diesel)*
Mechanical device which prevents filling the tank of a Diesel vehicle with petrol. It avoids the risk of
engine damage that can result from filling with the wrong fuel.
Located in the filler neck, the misfuel prevention device appears when the filler cap is removed.
When a petrol filler nozzle is introduced into the
fuel filler neck of your Diesel vehicle, it comes
into contact with the flap. The system remains
closed and prevents filling.
do no

Operation
Travelling abroad
As Diesel fuel pump nozzles may
be different in other countries, the
presence of the misfuel prevention
device may make refuelling impossible.
Not all Diesel vehicles are fitted with
misfuel protection, so before travelling
abroad, we recommend that you check
with the CITROËN dealer network,
whether your vehicle is suitable for the
fuel pumps in the country in which you
intend to travel.
* Depending on the country of sale.

9Hybrid4 system
When the Hybrid4 system is
started, this indicator lamp
comes on to signal that the
vehicle is ready to move off.
Illumination of this indicator lamp is more or
less instant but may take a few seconds in
some cases (pre-heating the HDi Diesel engine
in cold weather or in energy economy mode...).
READY lamp
Never leave the Hybrid4 system on
when leaving the vehicle, or opening
the bonnet, refuelling...
Before leaving the vehicle, ensure that
the READY
lamp is off.
This allows the high voltage battery to be
recharged using "free" energy
which can then
be reused
for future energy requirements.
CHARGE zone
POWER zone
Indicates an increased cumulative power
demand
from your vehicle, taking account
of the combined power available from the
HDi Diesel engine and the electric motor.
Power indicator
The indicator dial displays information on the total power used in real time, combining electric and
Diesel.
It comprises three operating zones.
Indicates that the vehicle
is optimising its energy
consumption
, electric, Diesel
or a combination of both.
ECO zone
This zone corresponds to phases of electric
running as well as to phases of optimum use
of the HDi Diesel engine, which are easily
accessible with a suitable driving style (smooth
"eco-citizen" driving).
Indicates that the vehicle is in
an electrical energy recovery
phase: on deceleration, braking
(partially) or particularly with
your foot off the accelerator.

Unsuitable circumstances:
- If the state of charge of the high voltage
battery is lower than 4 bars (equal to
50% charged). In AUTO
mode, electric
operation is possible with a lower state of
charge.
- When the speed of the vehicle exceeds
18 mph (30 km/h), if the internal combustion
engine has not already started at least once
since the Hybrid4 system was started.
- When the fuel level enters the reser ve
zone (illumination of the low fuel warning
lamp). Where this reser ve is is being used
up quickly, ZEV
may not be possible for
some time after refuelling.
- During phases of regeneration of the
particle filter (FAP), which is automatically
triggered approximately every 300 miles
(500 kms) for a period of about 10 minutes.
During regeneration of the particle filter,
the particles a brought up to a high
temperature using the HDi Diesel engine;
A message is then displayed: " Electric
mode not available: FAP regeneration
".
Maintaining the performance of
the system:
- If certain conditions or engine temperature
requirements needed by the HDi Diesel
engine are not met (for example, in wintry
conditions).
- Following a prolonged period with the
vehicle parked in the sun.
- When the state of charge of the high
voltage battery is close to the maximum
level (for example: when going down a long
hill using the electric motor for braking),
recovery of the vehicle's kinetic energy
being no longer possible, the HDI Diesel
engine restarts automatically just to
provide engine braking.
- On a steep rising slope.
- Driving at altitude.
