Stop & Start
Operation
Going into engine STOP mode
the "ECO" indicator lamp comes 
on in the instrument panel and the 
engine goes into standby:
-
 
w
ith a manual gearbox, at speeds below 
12 mph (20 km/h), or vehicle stationary 
with the e-
tH
P 165 version, when you put 
the gear lever into neutral and release the 
clutch pedal,
-
 
w
ith an automatic gearbox, vehicle 
stationary, when you press the brake pedal 
or you put the gear selector in position N .
If your vehicle is fitted with the system, a time 
counter calculates the sum of the periods in 
S
tO
P mode during a journey. It rests itself to 
zero every time the ignition is switched on with 
t h e key. Never refuel with the engine in 
S
tO
P   mode; you must switch off the 
ignition with the key. For your comfort, during parking 
maoeuvres, S
tO
P mode is not 
available for a few seconds after 
coming out of reverse gear.
S
tO
P mode does not affect the 
functionality of the vehicle, such as for 
example, braking, power steering...
th
e Stop & Start
 
system puts the engine 
temporarily into standby - S

P mode - 
during stops in the traffic (red lights, traffic 
jams, or other...).

instantly, quickly and silently.
Per fect for urban use, the Stop & Start system 
reduces fuel consumption and exhaust 
emissions as well as the noise level when 
stationary.

Hybrid4 system
508HY-comp_en_Chap00b_hybrid_ed01-2016
  The   electronic power super visor (4)  manages the operation of the two power units, HDi Diesel and electric, giving priority to low fuel consumption.  
  The   alternator-star ter motor (5)  assures the  Stop & Star t  function, which allows the HDi Diesel engine to be put into standby when the vehicle is at a standstill (traffic lights, a stop, or in a traffic jam...) or during phases of running in 100% electric mode. 
 The stopping and restarting of the HDi Diesel engine is done automatically and instantly without any action on the part of the driver.  This alternator-starter motor also provides additional charging of the high-voltage battery by the HDi Diesel engine, if this not sufficiently charged, or in  4WD  mode for example.  
  Compared to a manual gearbox, the  ETG6 electronic gearbox (6)  provides, in automatic mode, significant savings in fuel consumption, through the electronic management of gear changes.  
  The   mode selector (8)  allows selection of the four operating modes offered by the HYbrid4 system:    -    AUTO  mode, which optimises fuel consumption by automatically managing the alternate or simultaneous use of the two motors,   -    ZEV  (Zero Emissions Vehicle) mode, which provides 100% electric drive, when the driving conditions and the state of charge of the battery permit,   -    SPORT  mode, which provides more dynamic driving with additional per formance,   -    4WD  (4 Wheel Drive) mode, which improves traction at low speed when grip is poor (snow,  mud,  sand...).

  Activation of the HYbrid4 system 
  In wintry conditions with the engine cold, the Diesel pre-heating warning lamp can stay on for a few seconds; wait until it goes off before releasing the brake pedal.  
  In the event of non-activation of the HYbrid4 system:    If   N  is flashing in the instrument panel, move the gear selector to position  A  then to position  N .    If the " Foot on the brake "  is displayed, press the brake pedal f i r m l y.   
   Place the gear selector at position  N .    Insert the electronic key in the reader.   or    With Keyless Entry and Starting, simply having the electronic key inside the vehicle is  sufficient.   or    Insert the remote control key into the ignition switch and turn it towards the dashboard to position  2  (ignition on). 
    Press the brake pedal firmly.   Make a single short press (about one second) on the " START/STOP "  button.   or    Turn the remote control key fully towards the dashboard to position  3   (Starting).    Maintain pressure on the brake pedal until the  RE ADY  lamp comes on, signalling RE ADY  lamp comes on, signalling RE ADY
activation of the HYbrid4 system, confirmed by an audible signal.   
  On activation of the HYbrid4 system, the instrument panel lights up, the power indicator needle is placed at position " 0 ". The steering column automatically unlocks (perceptible noise and movement of the steering column).  Depending on certain parameters, such as the state of charge of the high voltage battery or the ambient temperature, the HYbrid4 system itself determines whether it is necessary to 
start the HDi Diesel engine.  The mode selector is at the  AUTO   position.

Frequently asked questions

  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 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   m o d e).  This allows some capacity to be left free for the recovery of energy when decelerating. 
 Why are there so many 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.
