If this warning lamp comes on in the instrument panel, automatic application / release is deactivated . The parking brake must be applied and released manually . manually . manually
Before leaving the vehicle, check that the the brake warning lamp and the P warning lamp in the control lever Aare on fixed (not flashing) .
If towing a trailer or caravan or if the slope might vary (transport by boat or lorry, recovery of the vehicle...) make a maximum application of the parking brake - by making a long pull on the control lever A - to immobilise the vehicle.
Driving safely
Electric parking brake
Manual Application/Release
Manual application of the parking brake is possible by pulling the control lever A . With the ignition on, manual release of the parking brake is possible by pressing the brake pedal and pulling then releasing the control lever A .
If an audible signal is heard on opening the driver's door with the hybrid system active, apply the parking brake manually. Do not leave a child alone in the vehicle with the ignition on; they might release the parking brake.

Hybrid system

Presentation
The Hybrid4 technology allows two sources of energy to be associated in an effective manner: the Diesel HDi engine, which drives the front wheels and the electric motor, which drives the rear wheels. These two motors can operate alternately or simultaneously, according to the hybrid 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 for running at slow speed and low load. It also assists the Diesel engine when moving off, accelerating and changing gear. The battery that powers the electric motor is recharged during phases of deceleration and stores the energy for subsequent use.
1. Diesel HDi engine (front wheel drive). 2. Electric motor (rear wheel drive). 3. 200 V battery. 4. Electronic power supervisor.
5. Alternator-starter motor (Stop & Start). 6. Electronic gearbox. 7. Electrical flow. 8. Hybrid4 mode selector.

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.
