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.

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.

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".

ZEV mode *
(all electric)
Zero emissions vehicle operation is assured 100 % by electric drive. This mode forces silent running at moderate speeds.
It can be activated when the required conditions are met, particularly if the state of charge of high voltage battery is sufficient (from 4 bars).
Auto mode
It automatically manages the operation of the Diesel engine and the electric motor, according to inherent vehicle parameters, traffic conditions and driving style so as to optimise the vehicle's fuel consumption . In particular, this mode activates "zero emissions" electric running when the conditions allow.
In auto mode, the electric motor : - can drive the vehicle on its own up to around 36 mph (60 km/h) 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 Diesel engine when moving off and changing gear, during acceleration and when traction from the front wheels is inadequate (it automatically adds 4 wheel drive ), - is no longer active above 70 mph (120 km/h).
* ZEV: Zero Emissions Vehicle.
This standard mode to use in preference is activated automaticallyon starting the hybrid system.

Sport mode
(Diesel and
electric)
4WD mode **
(Diesel and
electric)
This mode allows more dynamic driving by providing additional performance . Vehicle acceleration and pick-up are maximised by using the capacity of the electric motor, supplementing the power of the Diesel engine. This mode manages the progressiveness of the accelerator, the electronic gearbox and the use of the electric motor. In Sport mode: - The electric motor can be used up to 70 mph (120 km/h).
This mode provides additional traction *** at low speed by driving all 4 wheels of the vehicle continuously: the Diesel engine (front wheel drive) and the electric motor (rear wheel drive) operate simultaneously and permanently. Their coupling is managed electronically to optimise traction on slippery sur faces. In 4WD mode: - Power for the electric motor is provided, if needed, by the alternator-starter motor of the front engine. The Diesel engine operates continuously. - The additional traction from the electric motor is available up to 75 mph (120 km/h).
In ZEV mode: - Range and acceleration capacity are limited. The maximum speed possible is around 36 mph (60 km/h). - Under high load or a priority requirement causing the start of the Diesel engine, the system changes automatically to AUTO mode.
If the conditions do not allow this mode, a message that the "electric mode is not currently available" appears in the screen. The ZEV warning lamp flashes for a few seconds then goes off and the selector comes on in AUTO.
This mode should be used on snow covered roads or difficult ground (mud, sand, ...). In this mode, in severe conditions and if the circumstances allow, it is recommended that you accelerate strongly to ensure that you move off and avoid any risk of getting stuck. The addition of 4WD traction is available whatever: - the state of charge of the traction battery, - the altitude.
For more information on "Automatic restarting of the Diesel engine or ZEV mode not available", refer to the corresponding section.
** 4WD: 4 Wheel Drive. *** This mode will be even more effective if
suitable tyres are fitted (winter tyres in particular).

Energy consumption / generation indicator
The indicator dial provides real time information on the total power used, combining electric and Diesel. It comprises three main zones.
Zone which indicates that the vehicle is optimising its energy consumption , electric, Diesel or a combination of both. This zone corresponds to phases of electric running as well as to phases of optimum use of the Diesel engine, which are easily accessible with a suitable driving style (smooth "eco-citizen" driving).
Zone which indicates that the vehicle is in electrical energy recovery phase: on deceleration, braking (partially or particularly with your foot off the accelerator (to use in preference as this gives better energy recovery). This allows the high voltage battery to be recharged using "free" energy which can then be reused for future energy requirements.
ECO zone CHARGE zone

Examples of displays
On starting and when stationary
There is no flow of energy (the Stop & Start system stops and restarts the Diesel engine automatically).
Energy recovery
During this phase (deceleration, braking, foot off the accelerator, … all modes), the 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 then be less marked than with a conventional vehicle.
100% electric
In all electric running (AUTO or ZEV modes), only the electric motor, powered by the battery, drives the rear wheels. The display of "Zero Emission" indicates that the Diesel engine is off and the vehicle is producing no CO2.
