Hybrid4 system
Main parts of the Hybrid4 system
The HDi Diesel engine (1 ) , located at the front,
drives the front wheels and provides most of
the power needed to drive the vehicle.
The electric motor (2) , located at the rear
of the vehicle, drives the rear wheels on its
own, or supplements the HDi Diesel engine,
according to the Hybrid4 operating mode
selected.
This electric motor also manages the recovery
of energy, the charging of the batteries during
phases of deceleration of the vehicle. It is
active up to 70 mph (120 km/h).
The 200 V high voltage battery (3) , using Ni-
MH technology, stores and delivers the energy
needed for operation of the electric motor.
Its state of charge is managed automatically
by the electric motor during phases of
deceleration or by the HDi Diesel engine below
a certain threshold.
This high voltage battery is located in a special
compartment under the boot floor. Access
to it is strictly restricted to technicians at a
CITROËN dealer or a qualified workshop.
The state of charge of the high voltage battery
is represented graphically by bars.
See the "Display of energy flows" section.
Your Hybrid4 vehicle is fitted with effective
emissions control systems, including the
Particle Filter (FAP) .
During particle filter regeneration phases,
the HDi engine is called on to produce the
temperatures needed for combustion of the
particles.
Electric running is temporarily unavailable
and is accompanied by the display of a
message "
Electric mode not available: FAP
regeneration in progress ".
