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.
