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
f i r m l y .

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 ) .

Unsuitable circumstances:
- If the state of charge of the high voltage battery is lower than 4 bars (equal to 50% charged). In AUTO mode, electric operation is possible with a lower state of charge.
- When the speed of the vehicle exceeds 18 mph (30 km/h), if the internal combustion engine has not already started at least once since the Hybrid4 system was started.
- When the fuel level enters the reserve zone (illumination of the low fuel warning lamp). Where this reserve is is being used up quickly, ZEV may not be possible for some time after refuelling.
- During phases of regeneration of the particle filter (FAP), which is automatically triggered approximately every 300 miles (500 kms) for a period of about 10 minutes. During regeneration of the particle filter, the particles a brought up to a high temperature using the HDi Diesel engine; A message is then displayed: " Electric mode not available: FAP regeneration " .
Maintaining the performance of the system:
- If certain conditions or engine temperature requirements needed by the HDi Diesel engine are not met (for example, in wintry conditions).
- Following a prolonged period with the vehicle parked in the sun.
- When the state of charge of the high voltage battery is close to the maximum level (for example: when going down a long hill using the electric motor for braking), recovery of the vehicle's kinetic energy being no longer possible, the HDI Diesel engine restarts automatically just to provide engine braking.
- On a steep rising slope.
- D r i v i n g a t a l t i t u d e .

200 V high voltage battery
The 200 V high voltage battery is specially made for partial, rapid and frequent charging and discharging. Of Ni-MH (Nickel Metal Hydride) technology, it is located below the boot floor, close to the electric motor.
Charging
The battery recharges automatically while travelling. The battery is charged when the vehicle decelerates and when going downhill, the electric motor then becomes a generator and converts kinetic energy into electrical energy (except if the speed of the vehicle is above 70 mph (120 km/h)). This recovery allows the use of "free" energy. The battery may also be partially charged up to a level of 4 to 5 bars, using the alternator-starter motor (Stop & Start) of the HDi Diesel engine.
The average state of charge is 4 to 5 bars, so preserving a margin for energy recovery when deceleration of going downhill (free energy).
To preserve the service life of the battery, the level of charge never falls below 20%, even if a level of 0 bars is displayed after ZEV running. Where the battery is close to maximum, vehicle deceleration with your foot off the accelerator pedal will be at a lower l e v e l .
The battery charging time is very short. A discharged battery (following ZEV running or high load, for example) will quickly return to a state of charge sufficient (around 10 minutes) for full operation of the different hybrid modes.
The battery is not recharged from a mains power supply.

Frequently asked questions
100% electric mode (zero emissions)
QuestionAnswer
Why is it not always possible for me to select ZEV(Zero Emissions Vehicle) mode even though the battery seems well charged?
This situation is temporary. Certain conditions will occasionally prevent the change to ZEV mode, even if the battery has sufficient charge, such as, for example, very cold conditions, altitude, demisting, high demand for heating or air conditioning, regeneration of the particle filter (FAP).
Why do I sometimes see an alert message "Electric mode not available: FAP regeneration in progress"? This is an message relating to the regeneration of the particle filter (FAP). This is a completely normal process that takes place every 240 or 300 miles (400 or 500 km) (or more frequently in prolonged urban use), as on a conventional HDi Diesel vehicle. In the case of a conventional HDi Diesel vehicle, this process is not generally noticed by the driver. On the other hand, in the case of Hybrid4 this phenomenon may be noticeable (in urban use) as temporarily the HDi engine will not stop and this message will be displayed at intervals while regeneration is in progress.
Why is it not possible for me to put the vehicle into ZEVmode, even though I had just been running electrically in AUTO mode?
The management of ZEV is different from ZEV is different from ZEVAUTO mode. Changing to ZEV mode is only possible with a battery charge of at least 4 bars, in order to ZEV mode is only possible with a battery charge of at least 4 bars, in order to ZEVassure sufficient range. In AUTO mode, the system alone manages the conditions for changing temporarily to electric mode, for shorter periods and with a lower state of charge of the battery.
Why is the range in ZEV mode lower when going uphill? The vehicle needs more energy when going uphill than when running on the level. So it is better to stay in AUTO mode, which will favour operation of the HDi Diesel engine.
Why is it that the system makes me come out of ZEVmode; it does not return to ZEV mode automatically when the conditions allow?
It is not intended to give preference to ZEV running at any cost, as it is not always the most economical mode. So the system returns automatically to AUTO mode.

39Frequently asked questions
DS5Hy4_en_Chap11_questions-frequentes_ed01-2015
Reducing consumption / Fuel
QuestionAnswer
How can I optimise my fuel consumption? Give preference to AUTO mode as it selects in the best way the "driving energy source" to use in order to reduce fuel consumption. You should also adapt your driving style to the characteristics of hybrid vehicles to get the best out of it, for example by taking your foot off the accelerator pedal rather than braking and by anticipating decelerations which allows the recovery of "free" energy for charging the battery (entering a built-up area, stop at traffic lights, stop at halt signs, ...).
Why do I not manage to reduce my fuel consumption even though I often drive in ZEV (Zero Emissions Vehicle) mode?
It is not ZEV mode but AUTO mode that is the most appropriate for reducing fuel consumption, as it selects the best "driving energy source". ZEV mode (100% electric running) can reduce fuel consumption in some cases. However, recharging the traction battery has an energy cost. This is why we recommend using AUTO mode more often.
Why does the trip computer sometimes display the bars for 28 mpg (10 litres/100 km) in town? In traffic jams, the fuel consumption graph displayed may temporarily appear high when the distance covered is very low, but this generally has very little impact and the true average fuel consumption will remain low. In urban driving, your Hybrid4 will remain more efficient in terms of fuel consumption (by around 35%) compared to a conventional vehicle.
Why is my battery rarely fully charged? A partly charged battery is normal operation (4 to 5 bars on average in AUTO mode). This allows some capacity to be left free for the recovery for energy when going downhill or taking when your foot off the accelerator.
Why are there so may fuel alert messages when starting to use the reserve? To encourage you to refuel as soon as possible and to avoid loosing the possibility of all electric running.
