This system does not work continuously,
but adapts the force of the fan cooling to the requirements of the battery.
Its operation can be heard at the rear, even if
the vehicle is stopped after a run.
If the air intake is blocked, the battery may
overheat, damaging the battery and causing a
loss of performance of the hybrid system.







Fan cooling of the high voltage battery


For the best use of the high voltagebattery, please follow theserecommendations:


- do not obstruct the air intake with loose articles, otherwise, the battery may overheat, causing aloss of performance of the hybridsystem

- do not spill fluids, as this may cause damage to the battery.


The high voltage battery has an air cooling system, comprising an air intake(located on the side of the left hand rear seat) and a fan (located behind the lefthand boot trim panel).

49Hybrid system

The high voltage battery must not in anycircumstances be charged from an externalsource and must only be handled by a
workshop technician.
There is the risk o
f serious burns, as well as electric arcs that could cause serious injury or
even death.
A used Ni-MH (Nickel Metal Hydride) type
high voltage battery must be removed in an
appropriate manner by a repair workshop,so that its recycling presents no risk to the environment.

High voltage


The voltage used for the operation of theelectric motor is in the range 150 to 270 Volts.
Be sure to take account of the warning labels
fitted to the vehicle.
Ta k e great care regarding the high voltage and high temperatures of components carrying thecurrent.
Emergency cut-off
In the event of an accident, a cut-off system
blocks the high voltage current and cuts off
the fuel pump; your vehicle can no longer be started.To restar t the hybrid system, contact aCITROËN dealer.
High voltage cables are routed under the
vehicle
(sills); take care not to damage them
when the vehicle is used for off-road activity(such as covering rough ground).
Be
fore doing any work on
the vehicle, switch off the
ignition (Readylamp off). y
