Automatic restarting of
the Diesel engine
Various conditions can lead to restarting
or maintaining the Diesel engine, princi-
pally:
- during sustained and sharp ac-
celeration ,
- to maintain a comfortable tempera-
ture in the passenger compartment,
- when demisting,
- if the high voltage battery is not
suffi ciently charged,
-
in mountainous conditions (altitude),
- in certain temperature conditions
for the engine, such as a low am-
bient temperature (below 0 °C),
- if the temperature of the hybrid
system is too high,
- when using the vehicle after pro-
longed parking in a sunny area,
- when using the vehicle on a steep
slope,
- when regenerating the particle
emissions fi lter,
- fuel level too low.
In ZEV mode, these conditions lead
to an immediate change to AUTO
mode.
The Diesel engine is switched off auto-
matically as soon as these conditions
are lifted.
ECO OFF SWITCH
This function prevents the Diesel engine
being switched off and so ensures that
a comfortable temperature can be main-
tained in the passenger compartment
(air conditioning running continuously).
On pressing the switch, the engine re-
starts immediately.
To return to normal operation, press the
switch again.
After switching off the ignition, the vehi-
cle will return to normal operation (lamp
in the switch off).
Your vehicle is fi tted with the
most effective emissions con-
trol systems , in particular
the particle Emissions Filter
(PEF).
At regular intervals your Diesel en-
gine will produce energy for the self-
cleaning of this fi lter.
During this PEF regeneration phase,
electric running is purposely made
unavailable.
