Citroen DS5 HYBRID4 RHD 2011.5 1.G Workshop Manual

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.
Hi
gh voltage cables are routed under the
vehicle (sills); ensure that the vehicle is not
used for off-road activity (such as coveringrough ground) which could damage them.
