Weights and towed loads (in kg)
* The kerb weight is equal to the unladen weight + driver (75 kg). ** The weight of the braked trailer can be increased, within the GTW limit, if the GV W of the towing vehicle is reduced by an equal amount; warning, towing using a lightly loaded towing vehicle may have an adverse effect on its road holding. To make use of the 300 kg load transfer, the driver must be alone in the vehicle with no luggage in the vehicle.

The GTW and towed load values indicated are valid up to a maximum altitude of 1 000 metres; the towed load mentioned must be reduced by 10 % for each additional 1 000 metres of altitude. The maximum authorised speed is reduced when towing (comply with the legislation in force in your country). High ambient temperatures may result in a reduction in the per formance of the vehicle to protect the engine; if the ambient temperature is above 37 °C, limit the towed load.

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.

Air conditioning / Heating
QuestionAnswer
It seems to me that the vehicle runs less on electric when the heating or air conditioning is operating, is that right?
The demand for heating or air conditioning may require the starting of the HDi Diesel engine until the desired level of comfort is attained. Normal operation of the Hybrid4 system is simply put back. The period can be longer under very low or very high ambient temperatures.
It seems to me that when it is very hot and the air conditioning is working, the vehicle runs on electric for shorter periods. Is that right?
When it is hot, the periods when the HDi Diesel engine is put on standby and the vehicle runs on electric are necessarily restricted in order to limit the difference between the temperature in the vehicle and the level of comfort selected. In very hot weather, it is always possible to press the " ECO OFF " button (which brings the vehicle out of ZEV mode and prevents electric running or the stopping of the engine) to give preference to temperature control (keeps the air conditioning running).
Miscellaneous
QuestionAnswer
Is towing possible with my Hybrid4 vehicle? For information on the towing ability of your Hybrid4 vehicle, refer to " Weights and towed loads" in the "Technical data" section. This allows a jet ski or two-wheeler on a trailer to be towed, for example. This limit is related to maintaining adequate cooling capacity for the HDi Diesel engine as well as the hybrid components that are also cooled by the engine's cooling system.
Why does engine braking seem so strong? When you take your foot off the accelerator, the engine braking results mainly from the energy recovery by the electric motor. This leads to a higher level of deceleration than a conventional vehicle and so allows the recovery of "free" energy.
