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.
E
CO 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
restarts 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).
