Main parts of the Hybrid4 system
The HDi Diesel engine - 1 , located at the front, drives the front wheels and provides most of the power needed to drive the vehicle. It is fitted with an alternator-starter motor( Stop & Star t ) Stop & Star t ) Stop & Star t- 5 which recharges the batteries and provides additional power when needed (in 4x4 mode).
The electric motor - 2 , located at the rear, drives the rear wheels on its own, or supplements the Diesel engine, according to the hybrid mode selected. It recovers energy and charges the batteries during phases of deceleration of the vehicle and is active up to 70 mph (120 km/h).
A 200 V NI-MH high voltage batter y - 3 , provides a source of energy for the rear electric motor. Its charging rate is managed automatically by the vehicle during phases of deceleration. It is located in a compartment in the boot, access to which is restricted to trained service technicians.
The battery state of charge is indicated by 8 horizontal or vertical bars (depending on the screen).
The conventional battery , located under the conventional battery , located under the conventional batterybonnet, powers the vehicle's 12 V systems. It is recharged automatically by the high voltage network.

The electronic power super visor - 4automatically manages the operation of the two power units (Diesel and electric) to provide the lowest consumption. An inverter and a transformer are needed to manage the electric power. The inverter acts on the torque of the electric motor, by regulating the current coming from the high voltage battery pack. Its operating range is between 150 and 270 volts. The transformer converts the 200 V of the battery pack to 12 V, to power the vehicle's ancillary systems.
The alternator-starter motor - 5 assures the Stop & Star t function which allows the Diesel engine to be put into standby during stops (traffic lights, a stop, or in a traffic jam, for example) or during phases of running in all-electric mode. The stopping and restarting of the Diesel engine is done in a way that is instantaneous and transparent for the driver. It also provides additional charging of the batteries (4x4 mode for example or under-charged high voltage battery).
The electronic gearbox - 6 provides, in automatic mode, significant savings in fuel consumption compared to a conventional manual gearbox, thanks to its electronic control system. It also offers improved driving pleasure with the possibility at any time of choosing the gear changing mode: automatic or manual, using the paddles located behind the steering wheel.

Reducing consumption - Fuel
QuestionAnswer
How can I optimise my fuel consumption? Give preference to Auto mode as it selects in the best way the "driving energy source" to use in order to reduce fuel consumption. You should also adapt your driving style to the characteristics of hybrid vehicles to get the best out of it, for example by taking your foot off the accelerator pedal rather than braking and by anticipating decelerations (entering a built-up area, stop at traffic lights, stop at halt signs, ...).
Why do I not manage to reduce my fuel consumption even though I often drive in ZEV (Zero Emissions Vehicle) mode?
It is not ZEV mode but Auto mode that is the most appropriate for reducing fuel consumption, as it selects the best "driving energy source". ZEV mode (100% electric operation) can reduce fuel consumption in some cases. However, recharging the traction battery has an energy cost. This is why we recommend using Auto mode more often.
Why does the trip computer sometimes display the bars for 28 mpg (10 litres) consumption in
town?
The current fuel consumption displayed may appear high when the distance covered is very low, but this generally has very little impact and the true average fuel consumption will remain low.
In town, your hybrid retains very good fuel economy (of the order of 35% better than a non-hybrid vehicle).
Why is my battery rarely fully charged? A partly charged battery is normal operation (4 to 5 bars on average in Auto mode). This allows some capacity to be left free for the recovery for energy when going downhill or taking when your foot off the accelerator.
Why are there so may fuel alert messages when starting to use the reserve? To encourage you to refuel as soon as possible and avoid the loss of hybrid functions.

200 V high voltage battery
The 200 V high voltage battery cannot be recharged from a mains supply. The battery is Ni-MH (Nickel Metal Hydride) and is located below the boot floor, close to the electric motor.
Charging
The battery is charged when the vehicle decelerates, the electric motor then becomes a generator and converts kinetic energy into electrical energy (except if the speed of the vehicle is above 70 mph (120 km/h)). The battery is not recharged from a mains supply. The battery may also be charged automatically when required by the alternator-starter motor (Stop & Start) of the Diesel engine.
This recovery allows the use of "free" energy. The battery charging time is very short and is continuous. A discharged battery (following ZEV running or high load, for example) will quickly return to a state of charge sufficient for full operation of the different hybrid modes. The charging takes place automatically when driving . The energy recovery can be faster during deceleration. The average state of charge is 4 to 5 bars, so preserving a margin for energy recovery when deceleration of going downhill (free energy).
To preserve the service life of the battery, the level of charge never falls below 20 %, even if a level of 0 bars is displayed after ZEV running. Where the battery is close to maximum, vehicle deceleration with your foot off the accelerator pedal will be at a lower level.

Lighting left on audible signal
An audible signal when a front door
is opened warns the driver that the vehicle's exterior lighting is on, with the ignition off and in manual lighting mode. In this case, switching off the lighting stops the audible signal. With the ignition off, if the dipped headlamps remain on, the vehicle goes into "ECO" mode to avoid discharging the battery.
In some weather conditions (e.g. low temperature or humidity), the presence of misting on the internal sur face of the glass of the headlamps and rear lamps is normal; it disappears after the lamps have been on for a few minutes.
The daytime running lamps can be activated and deactivated via the configuration menu.
The lighting goes off when you switch off the ignition, but you can always switch it on again using the lighting control stalk.
Daytime running lamps
(LEDs)
They come on when the engine is started. Depending on the country of sale or where required by regulations, they are used for: - daytime running lamps in day mode and sidelamps in night mode (they are brighter when daytime running lamps), or - sidelamps in day and night mode.

Sit in a normal upright position. Wear a correctly adjusted seat belt. Do not leave anything between the occupants and the airbags (a child, pet, object...). This could hamper the operation of the airbags or injure the occupants. After an accident or if the vehicle has been stolen or broken into, have the airbag systems checked. All work on the airbag system must be carried out by a CITROËN dealer or a qualified workshop. Even if all of the precautions mentioned are observed, a risk of injury or of minor burns to the head, chest or arms when an airbag is deployed cannot be ruled out. The bag inflates almost instantly (within a few milliseconds) then deflates within the same time discharging the hot gas via openings provided for this purpose.
Lateral airbags
Use only approved covers on the seats, compatible with the deployment the lateral airbags. For information on the range of seat covers suitable for your vehicle, you can contact a CITROËN dealer. Refer to the "Accessories" section. Do not fix or attach anything to the seat backs (clothing...). This could cause injury to the chest or arms if the lateral airbag is deployed. Do not sit with the upper part of the body any nearer to the door than necessary.
Front airbags
Do not drive holding the steering wheel by its spokes or resting your hands on the centre part of the wheel. Passengers must not place their feet on the dashboard. If possible, do not smoke as deployment of the airbags can cause burns or the risk of injury from a cigarette or pipe. Never remove or pierce the steering wheel or hit it violently.
For the airbags to be fully effective, observe the following safety rules:
Curtain airbags
Do not fix or attach anything to the roof. This could cause injury to the head if the curtain airbag is deployed. If fitted on your vehicle, do not remove the grab handles installed on the roof, they play a part in securing the curtain airbags.

12 V battery
The presence of this label indicates the use of a 12 V lead-acid battery with special technology and specification, for which the involvement of a CITROËN dealer or qualified workshop is required when replacing or disconnecting the battery. Failure to observe this recommendation may cause premature wear of the battery.
The battery is located under the bonnet. To gain access to it:  open the bonnet using the interior release lever, then the exterior safety catch,  remove the plastic cover on the (+)
terminal,  if necessary, unclip the fusebox to remove the battery.
Access to the battery
 Raise the locking tab D fully to release the cable terminal clamp E .
Reconnecting the (+) cable
 Position the open clamp E of the cable on the positive post (+) of the battery.  Press vertically on the clamp E to position it correctly on the battery.  Lock the clamp by spreading the positioning lug and then lowering the tab D .
Do not apply excessive force on the tab as locking will not be possible if the clamp is not positioned correctly; start the procedure again.
Before doing any work on your vehicle, switch off the ignition ( Ready lamp off) to avoid any risk of injury resulting from automatic operation of the engine.
Your vehicle is fitted with a conventional 12 V battery, located under the bonnet, in addition to the high voltage battery used by the hybrid system. In certain conditions, if the 12 V battery is too discharged to activate the hybrid system, recharging from another conventional 12 V battery is possible. Do not carry out this recharge if the Readylamp is on.

After refitting the battery, the Stop & Start system will only be active after several hours depending on the climatic conditions and the state of charge of the battery (up to about 8 hours).
When your vehicle's battery is discharged, the engine can be started using a slave battery (external or on another vehicle) and jump lead cables.
Starting using another
battery
First check that the slave battery has a nominal voltage of 12 V and a capacity at least equal to that of the discharged battery. Do not try to start the engine by connecting a battery charger. Do not disconnect the (+) terminal when the engine is running.
 Remove the plastic cover from the (+) terminal, if your vehicle has one.  Connect the red cable to the positive terminal (+) of the flat battery A , then to the positive terminal (+) of the slave battery B .  Connect one end of the green or black cable to the negative terminal (-) of the slave battery B (or earth point on the other vehicle).  Connect the other end of the green or black cable to the earth point C on the broken down vehicle (or on the engine mounting).  Start the engine of the vehicle with the good battery and leave it running for a few minutes.
 Operate the starter on the broken down vehicle and let the engine run If the engine does not start straight away, switch off the ignition and wait a few moments before trying again.  Wait until the engine returns to idle then disconnect the jump lead cables in the reverse order.  Refit the plastic cover to the (+) terminal, if your vehicle has one.
 Disconnect the battery from the vehicle.  Follow the instructions for use provided by the manufacturer of the charger.  Connect the battery starting with the negative terminal (-).  Check that the terminals and connectors are clean.
