When the Hybrid4 system is started, this indicator lamp comes on to signal that the vehicle is ready to move off.
Illumination of this indicator lamp is more or less instant but may take a few seconds in some cases (pre-heating the HDi Diesel engine in cold weather or in energy economy mode...).

READY lamp
Never leave the Hybrid4 system on when leaving the vehicle, or opening the bonnet, refuelling... Before leaving the vehicle, ensure that the RE ADY lamp is off. RE ADY lamp is off. RE ADY
better energy recovery). This allows the high voltage battery to be recharged using "free" energy which can then be reused for future energy requirements.
CHARGE zone
POWER zone
Indicates an increased cumulative power demand from your vehicle, taking account of the combined power available from the HDi Diesel engine and the electric motor.
Power indicator
The indicator dial displays information on the total power used in real time, combining electric and Diesel. It comprises three operating zones.
Indicates that the vehicle is optimising its energy consumption , electric, Diesel or a combination of both.
ECO zone
This zone corresponds to phases of electric running as well as to phases of optimum use of the HDi Diesel engine, which are easily accessible with a suitable driving style (smooth "eco-citizen" driving).

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 ZEV modes), only the electric ZEVmotor 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
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 p o s i t i o n .
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.
Starting - switching off the Hybrid4 system
Never leave children alone inside the vehicle when the Hybrid4 system is a c t i v e .
 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.
 Press the brake pedal firmly.  Make a single short press (about one second) on the " START/STOP " button.  Maintain pressure on the brake pedal until the RE ADY lamp comes on, signalling RE ADY lamp comes on, signalling RE ADYactivation of the Hybrid4 system, confirmed by an audible signal.
If the Hybrid4 system does not start up:  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

Moving off
For more information on the ETG6 electronic gearbox and the electric parking brake, refer to the corresponding sections in the handbook for the vehicle.
You can change the operating mode of the Hybrid4 system at any time using its mode selector. Driving in ZEV mode requires that particular conditions be met.
When your vehicle vehicle moves off in electric mode, it makes no noise. Be very careful of pedestrians, cyclists... as, because of this, they will not hear you coming.
Head-up display
The colour of the speedometer varies according to the drive train used: - white display: Diesel engine running, - blue display: Diesel engine s t o p p e d .
Using automatic mode with the electronic gearbox optimises gear changes and so gives more economical driving.
 If automatic operation of the electric parking brake has been deactivated, pull the control lever to release the parking brake manually.  Progressively release the brake pedal. If the parking brake is released, the vehicle then moves off. If the parking brake is still applied and is in automatic mode, accelerate progressively.
 Move the gear selector to position A(automatic mode) or M (manual mode) or R ( r e v e r s e ) .

- 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.
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 ADYparking brake must be applied.
Check that the RE ADY lamp is off RE ADY lamp is off RE ADYbefore leaving the vehicle. Never leave the electronic key in the vehicle in your absence.
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 the ignition on
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 brake pedal , allows the ignition to be switched on.
 Press the " START/STOP " button, the instrument panel comes on but the Hybrid4 system does not start up.
With the ignition on, the system goes into energy economy mode when necessary to maintain the state of charge of the battery.
 Press this button again to switch off the ignition and so allow the vehicle to be l o c k e d .

ZEV mode
(all electric)
Zero emissions vehicle operation is assured 100 % by electric drive. This mode allows silent and clean running at moderate speeds.
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 enginewhen 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 m o d e .
For more information on the special conditions for the operation of ZEV mode, refer to the corresponding section.
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: ZEV mode: ZEV - 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 AUTO m o d e .

SPORT mode
(Diesel and
electric)
4WD mode
(4 - wheel
drive)
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. In SPORT mode: - the electric motor as an addition is available up to 75 mph (120 km/h).
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. 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).
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. The addition of 4WD traction is available whatever: - the state of charge of the 12 V
battery, - t h e a l t i t u d e .
* This mode will be even more effective if the vehicle is fitted with tyres suitable for winter conditions.

ECO OFF function
This function prevents the HDi Diesel engine being switched off and so ensures that a comfortable temperature can be maintained in the passenger compartment (air conditioning running continuously). On pressing the ECO OFF switch, the HDi Diesel engine restarts immediately. To return to normal operation, press this switch again. After switching off the ignition, the vehicle will return to normal operation (lamp in the switch off).
* E x c e p t i n ZEV mode, which gives preference to electric running over maintaining a comfortable temperature.
During electric running and when the engine is stopped, the hybrid system manages restarting automatically to maintain the temperature in the passenger compartment * . However, variations in temperature may still be felt in very hot climates. To avoid any discomfort in these conditions you can operate the ECO OFF s w i t c h .

A few driving recommendations
Observe the driving regulations at all times and remain vigilant whatever the traffic conditions. Pay close attention to the traffic and keep your hands on the wheel so that you are ready to react at any time to any eventuality. On a long journey, a break every two hours is strongly recommended. In difficult weather, drive smoothly, anticipate the need to brake and increase the distance from other vehicles.
Driving on flooded
roads
We strongly advise against driving on flooded roads, as this could cause serious damage to the internal combustion engine or electric motor, the electronic gearbox, or the electrical systems of your vehicle.
If you are obliged to drive through water:
- check that the depth of water does not exceed 15 cm, taking account of waves that might be generated by other users, - place the mode selector in the 4WDposition, - drive as slowly as possible without stalling. In all cases, do not exceed 6 mph (10 km/h), - do not stop and do not switch off the
engine. On leaving the flooded road, as soon as circumstances allow, make several light brake applications to dry the brake discs and pads. If in doubt on the state of your vehicle, contact a CITROËN dealer or a qualified workshop.
Important!
Never drive with the parking brake applied - Risk of overheating and damage to the braking system! Do not park or run the engine when stationary in areas where inflammable
substances and materials (dry grass, dead leaves...) might come into contact with the hot exhaust system or certain components of the Hybrid4 system which can reach very high temperatures - Risk of fire!
Never leave a vehicle unsupervised with the engine running. If you have to leave your vehicle with the engine running, apply the parking brake and put the electronic gearbox into position N .
