200 V high voltage battery
The 200 V high voltage battery is specially made for partial, rapid and frequent charging and discharging. Of Ni-MH (Nickel Metal Hydride) technology, it is located below the boot floor, close to the electric motor.
Charging
The battery recharges automatically while travelling. The battery is charged when the vehicle decelerates and when going downhill, the electric motor then becomes a generator and converts kinetic energy into electrical energy (except if the speed of the vehicle is above 70 mph (120 km/h)). This recovery allows the use of "free" energy. The battery may also be partially charged up to a level of 4 to 5 bars, using the alternator-starter motor (Stop & Start) of the HDi Diesel engine.
The average state of charge is 4 to 5 bars, so preserving a margin for energy recovery when deceleration of going downhill (free energy).
To preserve the service life of the battery, the level of charge never falls below 20%, even if a level of 0 bars is displayed after ZEV running. Where the battery is close to maximum, vehicle deceleration with your foot off the accelerator pedal will be at a lower l e v e l .
The battery charging time is very short. A discharged battery (following ZEV running or high load, for example) will quickly return to a state of charge sufficient (around 10 minutes) for full operation of the different hybrid modes.
The battery is not recharged from a mains power supply.

The high voltage battery must not in any circumstances be charged from an external source and must only be handled by a qualified technician at a CITROËN dealer or a qualified workshop. There is the risk of 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 the electric motor is in the range 150 to 270 Volts. Be sure to take account of the warning labels fitted to the vehicle. Take great care regarding the high voltage and high temperatures of components carrying the c u r r e n t .
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 restart the hybrid system, contact a CITROËN 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).
Before doing any work on the vehicle, switch off the ignition ( RE ADY l a m p o f f ) . RE ADY l a m p o f f ) . RE ADY
Battery precautions High voltage cables
Take care to position lifting equipment ( jack, hoist, ...) at the locations provided to avoid damaging the cables.
Never touch, dismantle, remove or replace the high voltage parts, orange cables or connectors, even in the event of an accident.

29Hybrid4 system

This ventilation system does not operate at the same speed at all times: it is continuously adjusted to suit the cooling requirements of the battery. The noise of its operation can be heard, particularly at the rear, after the Hybrid4 system is switched off (post-ventilation). If the air intake is blocked, the battery may overheat, damaging the battery and causing a loss of per formance of the Hybrid4 system.
Ventilation of the high voltage battery
For the best use of the high voltage battery, please observe the following safety recommendations: - do not obstruct the air intake with loose articles, otherwise, the battery may overheat, which could cause a loss of per formance of the Hybrid4 system, - do not spill fluids, as this may damage the battery (short-circuit).
The high voltage battery has an air cooling system. This comprises an air intake (located on the side of the left hand rear seat) and a fan (located behind the left hand boot trim panel).

Access to the underbonnet
The alternator-starter 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 restarting at any t i m e .
Always ensure that the ignition is switched off ( RE ADY lamp off) RE ADY lamp off) RE ADYbefore opening the bonnet.
Before doing anything under the bonnet, to avoid the risk of serious injury, switch off the ignition and verify that the RE ADY lamp in the instrument RE ADY lamp in the instrument RE ADYpanel is off.

Recovery of the vehicle on a fl at-bed
Never recover the vehicle by towing it with two or four wheels on the ground, as there is a risk of damage to the transmission. However, if necessary because access to the vehicle is difficult, the vehicle can be moved a few dozen metres, at a speed of less than 6 mph (10 km/h).
Use the towing eye only to pull the vehicle out or to lash it for recovery on a flat-bed lorry or
