Frequently asked questions

  Reducing consumption / Fuel  

   Question   

   Answer   

 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 fuel consumption histogram sometimes 
display consumption of 28 mpg (10 litres/100 km) in 
town? 

 In traffic jams, the fuel consumption graph may temporarily display high values but, as the 
distance covered is low, this has very little impact on the average fuel consumption. 
 In urban driving, your Hybrid4 will remain more efficient in terms of fuel consumption 
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 of energy when decelerating. 

 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  

   Question   

   Answer   

 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 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  

   Question   

   Answer   

 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 components of the Hybrid4 system that are also cooled by the engine's cooling 
system. 

 Why does engine braking seem so strong? 

 If the high voltage battery is not fully charged, the engine braking results mainly from the 
energy recovery by the electric motor. The power of this engine braking is higher than that 
of an internal combustion engine.
