On starting and when stationary
There is no flow of energy; the Stop & Start alternator-starter stops and restarts the HDi Diesel engine automatically, whatever the operating mode selected.
Energy recovery
During this phase (deceleration, braking, foot off the accelerator, … all modes), the high voltage battery is recharged by the electric motor/generator, then being driven by the rear wheels. You can maximise this energy recovery by taking your foot off the accelerator pedal; deceleration will be less marked than with a conventional vehicle.
100% electric
In all electric running (AUTO or ZEV modes), only the electric motor drives the vehicle, via the rear wheels, powered by the high voltage battery. The display of " Zero Emission " indicates that the HDi Diesel
engine is stopped and the vehicle is producing no CO2.

Activation of the HYbrid4 system
In wintry conditions with the engine cold, the Diesel pre-heating warning lamp can stay on for a few seconds; wait until it goes off before releasing the brake pedal.
In the event of non-activation of the HYbrid4 system:  If N is flashing in the instrument panel, move the gear selector to position A then to position N .  If the " Foot on the brake " is displayed, press the brake pedal f i r m l y.
 Place the gear selector at position N .  Insert the electronic key in the reader. or  With Keyless Entry and Starting, simply having the electronic key inside the vehicle is sufficient. or  Insert the remote control key into the ignition switch and turn it towards the dashboard to position 2 (ignition on).
 Press the brake pedal firmly. Make a single short press (about one second) on the " START/STOP " button. or  Turn the remote control key fully towards the dashboard to position 3 (Starting).  Maintain pressure on the brake pedal until the RE ADY lamp comes on, signalling RE ADY lamp comes on, signalling RE ADY
activation of the HYbrid4 system, confirmed by an audible signal.
On activation of the HYbrid4 system, the instrument panel lights up, the power indicator needle is placed at position " 0 ". The steering column automatically unlocks (perceptible noise and movement of the steering column). Depending on certain parameters, such as the state of charge of the high voltage battery or the ambient temperature, the HYbrid4 system itself determines whether it is necessary to
start the HDi Diesel engine. The mode selector is at the AUTO position.

Switching the ignition on
Turn the remote control key towards the dashboard to position 2 (ignition on) or, with the electronic key of the Keyless Entry and Starting system inside the vehicle, press the " S TA R T/STOP " button, with no action on the brake pedal to switch on the ignition for temporary use of the vehicle's ancillary equipment.
 Press the " START/STOP " button, the instrument panel comes on but the HYbrid4 system does not start.  Press this button again to switch off the ignition and allow the vehicle to be locked.
With the ignition on, the system automatically changes to economy mode when required to maintain an adequate state of charge of the battery.
For reasons of safety and theft protection, do not leave your electronic key in the
vehicle, even when you are close to it. It is recommended that you keep it on your person.
Switching off the HYbrid4 system
 Immobilise the vehicle.  Place the gear selector in position N .  Make a short press (about one second) on the " START/STOP " button. or  Turn the remote control key fully towards you to position 1 (Stop).
Check that the RE ADY lamp is off RE ADY lamp is off RE ADYbefore leaving the vehicle. Never leave the electronic key inside the vehicle in your absence.
The HYbrid4 stops: - the RE ADY lamp goes off, RE ADY lamp goes off, RE ADY - the steering column locks, - the electric parking brake is applied automatically, unless its automatic mode is deactivated.
 Check that the parking brake warning lamps are on.  Remove the electronic key from the reader. or  Remove the remote control key from the ignition switch.
Before doing anything under the bonnet, the HYbrid4 must be switched off ( RE ADY lamp off) and the electric RE ADY lamp off) and the electric RE ADY
parking brake must be applied.

AUTO mode
This mode is designed to optimise the vehicle's fuel consumption by managing the alternate or simultaneous operation of the two motors according to the conditions and driving style. When conditions allow, an adequate battery state of charge and moderate acceleration, the alternator-starter motor stops the HDi Diesel engine to provide 100% electric running.
Z E V m o d e
(all electric)
Zero emissions vehicle operation is assured 100 % by electric drive. This mode allows silent and clean running at moderate speeds.
If the conditions do not allow ZEV mode to be selected or maintained, the message " Electric mode is not currently available " appears in the screen. The ZEV indicator lamp flashes for a few seconds then goes off and the indicator lamp in the AUTO position comes on. In ZEV mode: - range and acceleration capacity are limited; the maximum speed is around 36 mph (60 km/h), - under high load or a priority requirement causing the start of the HDi Diesel engine, the system changes automatically to AUTOmode.
For more information on the special conditions for the operation of ZEVmode, refer to the corresponding section.
It can be activated when the conditions allow, particularly if the state of charge of high voltage battery is sufficient (from 4 bars).
In AUTO mode, the electric motor : - can power the vehicle on its own in "zero emissions" electric running, depending on the state of charge of the battery, if the conditions specific to the vehicle are met
and if acceleration is moderate, - supplements the HDi Diesel engine when moving off and changing gear, during acceleration or when traction from the front wheels is inadequate, temporarily providing 4-wheel drive. The electric motor can operate only at speeds below 52 mph (85 km/h). It is no longer active above 75 mph (120 km/h).
Refer to the special conditions for operation of ZEV mode.

S P O R T m o d e
(Diesel and
electric)
This mode allows more dynamic driving by providing additional performance . By using the capacity of the electric motor to supplement the power of the HDi Diesel engine, the vehicle's full power is used for acceleration and pick-up. This mode manages the response of the accelerator, the electronic gearbox and the use of the electric motor.
4 W D m o d e
(4 - wheel
drive)
This "4-wheel drive" mode provides additional traction at low speed by driving all four wheels of the vehicle simultaneously: the HDi Diesel engine (front wheel drive) and the electric motor (rear wheel drive) operate simultaneously and permanently. Their coupling is managed electronically to optimise traction when grip is poor.
This mode should be used on snow covered roads or difficult ground (mud, sand, ...), as well as for crossing a ford, at moderate speed. In this mode, in severe conditions and if the circumstances allow, it is recommended that you accelerate strongly to facilitate moving off and making progress and so reduce the risk of getting stuck.
This mode will be even more effective if the vehicle is fitted with suitable tyres, such as winter tyres.
In 4WD mode: - the HDi Diesel engine operates continuously; if necessary, it supplies energy for the electric motor, - the additional traction from the electric motor is available up to 75 mph (120 km/h).
In SPORT mode: - the electric motor as an addition is available up to 75 mph (120 km/h).
This mode is available whatever: - the state of charge of the high voltage battery, - the altitude.

Special conditions for the operation of ZEV mode
ZEV mode can be selected when all of the conditions for its operation are met, in particular an adequate state of charge of the battery (50% at least). In the situations described below, the HDi Diesel must be running; accordingly, ZEVmode cannot be selected or is deactivated automatically. The mode selector remains at or returns to the AUTO position to allow starting of the HDi Diesel engine.
Cases of non availability of ZEV mode or automatic return
to AUTO mode
- Manual gear change when in automatic mode using the steering mounted controls
for the electronic gearbox.
- Selection of manual mode by moving the gear selector for the electronic gearbox to position M .
- Sustained and sharp acceleration.
- Use of demisting / defrosting.
- Intensive use of air conditioning.

Maintaining the performance of the system:
- 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 ".
- 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.
- 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.

200 V high voltage battery
The Ni-Mh (Nickel-Metal Hydride) technology used for the high voltage battery is suited to the frequent partial charging and discharging cycles related to the operation of a hybrid vehicle. The battery is installed close to the electric motor, below the boot trim, behind the storage well.
Charging
The battery recharges automatically while travelling. The battery is charged when the vehicle decelerates and when going downhill, 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)). This recovery allows the use of "free" energy. The battery may also be partially charged up to a level of 4 to 5 bars, using the alternator-starter motor (Stop & Start) of the HDi Diesel engine.
The battery charging time is very short.
To preserve the service life of the battery, the level of charge never falls below 20%, even if no bars are displayed on the gauge after ZEVrunning. Where the battery is close to maximum,
vehicle deceleration with your foot off the accelerator pedal will be at a lower level.
The average state of charge is 4 to 5 bars, so preserving a margin for energy recovery when deceleration or going downhill (free energy).
The battery is not recharged from a mains power supply.
Once it is discharged, following ZEV running or high load, the battery will reach its optimum
level of charge after around 10 minutes.
