49Hybrid system








Consumption of your hybrid in the screen

Average consumption over the last 5 minutes.
"60 % H
ybrid Use" corresponds to 60 % of the cumulative
running time with the addition of the hybrid system and
40 % of the time with the Diesel engine only (with no contribution from the hybrid system).


For more information on the trip computer, refer to the corresponding section.
Resetting the history

With the hybrid system active, when trip 2 displayed, press
the control for 2 seconds to reset the history to zero.

200 V high voltage battery
The 200 V high voltage battery cannot berecharged from a mains supply.
The battery is Ni-MH (Nickel Metal Hydride) and is located below the boot floor, close to the electric motor.

Charging


The battery is charged when the vehicle
decelerates, the electric motor then becomes
a
generator and conver ts kinetic energy intoelectrical 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 b
y the Stop & Start system of
the Diesel engine.
This recover
y allows the use of "free" energy.
The battery charging time is very shor t and iscontinuous.
A discharged battery (following ZEV running or high load, for example) will quickly return to astate of charge sufficient for full operation of the
different hybrid modes.
The charging takes place automaticallywhen driving.
The energy recovery can be faster during deceleration.
The average state of charge is 4 to 5 bars, sopreserving a margin for energy recovery when
deceleration of going downhill (free energy).
To preser ve the ser vice life of thebattery, the level of charge never fallsbelow 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 level.

51Hybrid system

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 mayoverheat, 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 these recommendations:


- do not obstruct the air intake withloose 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).

The high voltage battery must not in anycircumstances be charged from an external source 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 andhigh temperatures of components carrying the current.

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 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).
Be
fore doing any workon the vehicle, switch off the ignition (Readylamp off).



Battery precautions

Hi
gh 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 par ts, orange cables or connectors, even in the eventof an accident.

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 the
ignition is switched off (Readylamp off) before
opening the bonnet.
Also ensure that the ignition is switchedoff when refuelling to avoid the engine restarting.

Car washing machine or tunnel
the wash.
With the hybrid system active, Ready
lamp on, parking brakereleased: - Place the gear selector in position N.- Switch off the engine (press on STA R T/STOP). The parking brake is applied automatically and the Ready
lamp goes off inthe instrument panel.- Switch on the ignition again (press on START/STOP) without your foot on the brake pedal. The Ready
lamp remains off. - Release the parking brake using the manual control on thecentre console, while keeping your foot on the brake pedal. - Switch off the ignition (press on STA R T/STOP without your foot on the brake pedal) checking that the parking brake
remains released.



If the Diesel engine is not running, it restar ts.If the Diesel engine is running, it remains running without timelimit.

With the hybrid system active, Readylamp on, parking brakereleased: - Place the gear selector in position N(Auto or Sport mode). - Press the brake pedal then the ECO OFF button.
Car washing machines or tunnels in which theDiesel engine must be switched off.
Car washing machines or tunnels in which the Diesel engine must not be switched off.

Vehicle recovery


Before doing any work, with the ignition on, press the brake pedal and put the gear selector to
position N, then switch off the hybrid system.
If necessary because access to the vehicle is difficult, it can be moved a few dozen metres at a speed not exceeding 6 mph (10 km/h).
Use the towing eyes only to pull a vehicle out or
to pull it onto a flat-bed.

The front or rear wheels must not be on theground, use a flat-bed lorry or trailer to recover
t
he vehicle.
