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.
Automatic Application / Release
Press the accelerator pedal, the parking brake is released automatically and progressively as you move off. With the vehicle stationary, the parking brake is applied automatically on switching off the ignition ( Ready lamp off).

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.

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.

31Hybrid system
Before starting
- Place the gear selector lever in position N . - If your vehicle has Keyless Entry and Starting, simply having the key inside the vehicle is sufficient. - If not, place the electronic key in the reader.
- Press the brake pedal. - Make a single short press (about a second) on the START/STOP button. - The steering column locks (noticeable noise and movement of the steering wheel). - Keep your foot on the brake pedal until the Hybrid4 system starts up (the instrument panel and the Ready lamp come on, confirmed by an audible signal).
Starting the Hybrid4 system
Starting - switching off the engine
The hybrid system determines whether it is necessary to start the Diesel engine.
When your vehicle vehicle moves off
in electric mode, it makes no noise. Be ver y careful of pedestrians and cyclists as they will not hear you coming.

Switching off the Hybrid4
system
- Before switching off the Hybrid4 system, place the gear selector in position N . - Make a short press on the START/STOPbutton. - The system shuts down and the steering column locks. For more information, see the section on "Underbonnet precautions/warnings".
When stationary, switch off the ignition and check that the Ready lamp is off before leaving the vehicle, otherwise the hybrid system will still be active.

Anti-theft protection
Electronic engine immobiliser
The keys contain an electronic chip which has a secret code. When the ignition is switched
on, this code must be recognised in order for starting to be possible. This electronic engine immobiliser locks the engine management system a few minutes after the ignition is switched off and prevents starting of the engine by anyone who does not have the key. In the event of a malfunction, you are informed by a message in the instrument panel screen. In this case, your vehicle does not start; contact a CITROËN dealer as soon as possible.
Ignition on without
starting
With the electronic key in the reader or the Keyless Entry and Starting key inside the vehicle, pressing the "START/STOP" button, with no action on the pedals , allows the ignition to be switched on.
Press the "START/STOP" button, the instrument panel comes on but the engine does not start. Press the button again to switch off the ignition and so allow the vehicle to be locked.
With the ignition on, the system goes into energy economy mode when necessary to maintain the state of charge of the battery.

Back-up starting with the Keyless Entry and Starting system
When the electronic key is in the defined zone and your vehicle does not start after pressing the "START/STOP" button: Insert the electronic key in the reader. Press the brake pedal. Press the "START/STOP" button. The hybrid system is active.
Back-up switch-off
In the event of an emergency only, the engine can be switched of without any conditions. To
do this, press and hold the "START/STOP" button for about 3 seconds. In this case the steering column locks as soon as the vehicle stops.
Electronic key not recognised by the "Keyless Entry and Starting" system
If the electronic key is no longer in the defined zone when driving or when you (later) request switching off of the hybrid system, a message appears in the instrument panel.
Press and hold the "START/STOP" button for about 3 seconds if you want to force
switching off of the hybrid system (note that restarting will not be possible without the electronic key in the defined zone).
The electronic key must always remain inside the vehicle when in use.

Hybrid4 mode selector
The selector allows the user to choose between 4 drive modes for the vehicle. Turn the dial to the right or left; the mode selected is confirmed by illumination of the corresponding i n d i c a t o r.
ZEV mode, to force electric running.
SPORT mode, to make use of the maximum per formance of the vehicle.
4WD mode, to force the vehicle into 4x4 mode.
AUTO mode, for normal use and optimised fuel consumption.
On starting the vehicle: with the gear selector in position N , press the brake pedal and press the START/STOP button to activate the hybrid system. This lamp comes on when the vehicle is ready to move off ("Auto" mode is on by default) and so the driver can press the accelerator. This lamp comes on more or less instantly but may take a few seconds in some cases (in particular, the time needed for pre-heating the Diesel engine in cold weather or, for example, in energy economy mode, ...).
Ready lamp
With the vehicle stationary, press the START/STOP button and check that the Ready lamp is off when leaving the vehicle, other wise the hybrid system will still be active.
For more information, refer to the section on "Underbonnet precautions / warnings".
