2011.5 Citroen DS5 HYBRID4 RHD engine

47Hybrid system








200 V high voltage battery


The Ni-MH (Nickel Metal Hydride) type 200 V high voltage battery is located below the boot
floor, close to the electric motor. It cannot be
recharged from a mains supply.
Charging
The battery is charged when the vehicle
decelerates, the electric motor then becominga generator and conver ts kinetic energy into
electrical energy (except if the speed of the
vehicle is above 70 mph (120 km/h)).
The battery is not recharged from a mains
supply.
The battery may also be charged automatically
when required by the Stop & Start system of
the Diesel engine.
This recover
y allows the use of "free" energy.
The battery charging time is very short and iscontinuous.
A discharged battery (following ZEV running or high load, for example) will quickly return to
a state of charge sufficient for full operation of
the different hybrid modes.
The recharge takes place automatically
when driving .
The energy recovery can be faster during deceleration.
To preser ve the ser vice life of thebattery, the level of charge never falls below 20 %, even if a level of 0 bars is displayed after ZEV running.

Underbonnet precautions/warnings
The alternator-star ter motor of your hybrid
vehicle is also supplied at high voltage. If the
vehicle ignition has not been switched off, there
is a risk of the engine restar ting at any time.
Alwa
ys ensure that theignition is switched off ( Readylamp off) before
opening the bonnet.
Also ensure that the ignition is switchedoff when refuelling to avoid the enginerestarting.

Monitoring
Indicator and warning lamps
When the engine is star ted, these same warning lamps should go off.
If they remain on, before moving off, refer to

gine may cut out.
Park, switch off the ignition and call a CITROËN
dealer or a qualified workshop.



Serviceon temporarily. A minor fault has occurred for which
there is no specific warning lamp. Identify the fault by reading the message shown in the screen, such as, for example:
- the closing of the doors, boot or bonnet,
- the engine oil level,
- the screenwash level,
- the remote control battery,
- the tyre pressures,
- saturation of the par ticle emission filter (Diesel). - ...For any other faults, contact a CITROËN dealer or a
qualified workshop.
