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).

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.
