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:
-

efore a long journey,
-

t each change of season,
-

fter 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
(3 000 kilometres) that you will see the fuel consumption settle down to
a consistent average.

Opening the filler cap may result in an inrush of
air. This vacuum is entirely normal and results
from the sealing of the fuel system.

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
s l ow l y.
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.

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.
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 want to travel.
* According to 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 RE ADY lamp is off. RE ADY lamp is off. RE ADY
better energy recovery). 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 recoveryphase: on deceleration, braking (partially or particularly with your foot off the accelerator, to use in preference as this gives

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 reserve zone (illumination of the low fuel warning lamp). Where this reserve 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.
