19Hybrid4 system
Mode selector
The selector allows the driver to select one of the four operating modes offered by the Hybrid4
system.
)
Turn the dial to the right or left; the mode selected is confirmed by illumination of the
corresponding indicator lamp.
ZEV
mode: for 100% electric running.
SPORT
mode: to make use of the maximum
per formance of the vehicle.
4WD
mode: to force 4x4 drive in conditions of
poor grip.
AUTO
mode: for everyday use and optimised
fuel consumption.
By default, the selector is in the AUTO
position when starting the Hybrid4 system, whatever
position it was in when the ignition was switched off.
AUTO mode
This mode is designed to optimise the vehicle's
fuel consumption by managing the alternate
or simultaneous operation of the two motors
according to the conditions and driving style.
When conditions allow, an adequate battery
state of charge and moderate acceleration, the
alternator-starter motor stops the HDi Diesel
engine to provide 100% electric running.

"ECO OFF" function
This function prevents the HDi Diesel engine being
switched off and ensures that a comfortable temperature
can be maintained in the passenger compartment.
This therefore allows the air conditioning or heating to be
kept running.
Depending on version, the control is either in
the switch panel alongside the steering wheel,
or in the " Driving
" menu of the touch screen.
On pressing the ECO OFF
switch, the
HDi Diesel engine restarts immediately and
then operates continuously.
The indicator lamp in the control comes on.
Pressing this control again deactivates the
function.
The indicator lamp in the control goes off.
The Hybrid4 system returns to normal
operation.
*
Except in ZEV mode, which gives preference
to electric running over maintaining a
comfortable temperature.
The function is deactivated on
switching off the ignition.
During phases of electric running and
when the internal combustion engine is
stopped, the Hybrid4 system manages
restarting automatically to maintain
the temperature in the passenger
compartment * .
However, variations in temperature
may still be felt in very high ambient
temperatures.
In this case, activate the ECO OFF
function.
With the switch on the dashboard
)
Press this switch.
Deactivation is confirmed by the illumination of

27Hybrid4 system
200 V high voltage battery
The Ni-Mh (Nickel-Metal Hydride) technology
used for the high voltage battery is suited to
the frequent partial charging and discharging
cycles related to the operation of a hybrid
vehicle.
The battery is installed close to the electric
motor, below the boot trim, behind the storage
well.
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
conver ts 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
preser ving a margin for energy recovery when
deceleration or going downhill (free energy).
To preser ve the ser vice life of the
battery, the level of charge never
falls below 20%, even if no bars are
displayed on the gauge after ZEV
running.
Where the battery is close to maximum,
vehicle deceleration with your foot off
the accelerator pedal will be at a lower
level.
The battery charging time is very short.
Once it is discharged, following ZEV
running
or high load, the battery will reach its optimum
level of charge after around 10 minutes.
The battery is not recharged from a
mains power supply.

43Frequently 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 reser ve? To encourage you to refuel as soon as possible and to avoid loosing the possibility of all
electric running.
