Presentation of the HYbrid4 system
The HYbrid4 technology associates two sources of power: an HDi Diesel engine, which drives the front wheels and an electric motor, which drives the rear wheels. These two motors can operate alternately or simultaneously, according to the HYbrid4 operating mode selected and the driving conditions. The electric motor alone provides power for the vehicle in ZEV (Zero Emissions Vehicle) mode, and in AUTO mode when running at slow speed and under low load. The electric motor also assists the HDi Diesel engine when moving off, accelerating and changing gear. The electric motor is powered by a high voltage battery that is recharged during phases of deceleration as well as, up to a certain threshold, by the HDi Diesel engine.
1. HDi Diesel engine (driving the front wheel).
2. Electric motor (driving the rear wheels). 3. 200 V high voltage battery. 4. Electronic power supervisor.
5. Alternator-starter motor (Stop & Start).
6. Electronic gearbox (ETG6). 7. Electrical flow. 8. Mode selector.

The electronic power super visor (4) manages the operation of the two power units, HDi Diesel and electric, giving priority to low fuel consumption.
The alternator-star ter motor (5) assures the Stop & Star t function, which allows the HDi Diesel engine to be put into standby when the vehicle is at a standstill (traffic lights, a stop, or in a traffic jam...) or during phases of running in 100% electric mode.
The stopping and restarting of the HDi Diesel engine is done automatically and instantly without any action on the part of the driver. This alternator-starter motor also provides additional charging of the high-voltage battery by the HDi Diesel engine, if this not sufficiently charged, or in 4WD mode for example.
Compared to a manual gearbox, the ETG6 electronic gearbox (6) provides, in automatic mode, significant savings in fuel consumption, through the electronic management of gear changes.
The mode selector (8) allows selection of the four operating modes offered by the HYbrid4 system: - AUTO mode, which optimises fuel consumption by automatically managing the alternate or simultaneous use of the two motors, - ZEV (Zero Emissions Vehicle) mode, which provides 100% electric drive, when the driving conditions and the state of charge of the battery permit, - SPORT mode, which provides more dynamic driving with additional per formance, - 4WD (4 Wheel Drive) mode, which improves traction at low speed when grip is poor (snow, mud, sand...).

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.

Starting the HYbrid4 system
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.
