Unsuitable circumstances:
- If the state of charge of the high voltage
battery is lower than 4 bars (equal to
50% charged). In
AUTO mode, electric
operation is possible with a lower state of
charge.
- When the speed of the vehicle exceeds
18 mph (30 km/h), if the internal combustion
engine has not already started at least once
since the Hybrid4 system was started.
- When the fuel level enters the reserve
zone (illumination of the low fuel warning
lamp). Where this reserve is is being used
up quickly,
ZEV may not be possible for
some time after refuelling.
- During phases of regeneration of the
particle filter (FAP), which is automatically
triggered approximately every 300 miles
(500 kms) for a period of about 10 minutes.
During regeneration of the particle filter,
the particles a brought up to a high
temperature using the HDi Diesel engine;
A message is then displayed: "
Electric
mode not available: FAP regeneration ".
Maintaining the performance of
the system:
- If certain conditions or engine temperature
requirements needed by the HDi Diesel
engine are not met (for example, in wintry
conditions).
- Following a prolonged period with the
vehicle parked in the sun.
- When the state of charge of the high
voltage battery is close to the maximum
level (for example: when going down a long
hill using the electric motor for braking),
recovery of the vehicle's kinetic energy
being no longer possible, the HDI Diesel
engine restarts automatically just to
provide engine braking.
- On a steep rising slope.
- Driving at altitude.
