2013 Citroen DS5 HYBRID4 stop start

41Hybrid system

Examples of displays


On starting and when stationary

There is no flow of energy (the Stop & Star t system stops and
restar ts the Diesel engine automatically).

Energy recovery

During this phase (deceleration, braking, foot off the
accelerator, … all modes), the battery is recharged by the electric motor/generator, then being driven by the rear wheels.
You can maximise this energy recovery by taking your foot off
the accelerator pedal, deceleration will then be less marked
th
an with a conventional vehicle.

100% electric

In all electric running (AUTO or ZEV modes), only the electric motor, powered by the battery, drives the rear wheels.
The display of "Zero Emission" indicates that the Diesel engine
is off and the vehicle is producing no CO2.

Reducing consumption - Fuel
QuestionAnswer
How can I optimise m
y fuel consumption? Give preference to Auto mode as it selects in the best way the "driving energy source" to use in
order to reduce fuel consumption.
You should also adapt
your driving style to the characteristics of hybrid vehicles to get the best
out of it, for example by taking your foot off the accelerator pedal rather than braking and by
anticipating decelerations (entering a built-up area, stop at traffic lights, stop at halt signs, ...).
Wh
y do I not manage to reduce my fuel consumption even though I often drive in ZEV(Zero Emissions Vehicle) mode?It is not ZEV mode but Auto mode that is the most appropriate
for reducing fuel consumption, as it selects the best "driving energy source".
ZEV mode (10 0% electric operation) can reduce fuel consumption in some cases. However,
recharging the traction battery has an energy cost.
This is why we recommend using Auto mode more often.
Wh
y does the trip computer sometimes displaythe bars for 28 mpg (10 litres) consumption in
town? The current fuel consumption displa
yed may appear high when the distance covered is very low,
but this generally has very little impact and the true average fuel consumption will remain low.
In town, your hybrid retains very good fuel economy (of the order of 35% better than a non-hybrid
vehicle).
Wh
y is my battery rarely fully charged? A partly charged battery is normal operation (4 to 5 bars on average in Auto mode).
This allows some capacity to be left free for the recovery for energy when going downhill or takingwhen your foot off the accelerator.
Wh
y are there so may fuel aler t messages whenstarting to use the reser ve?To e n c o u r age you to refuel as soon as possible and avoid the loss of hybrid functions.

ECO OFF switch
This function prevents the Diesel engine
being switched off and so ensures that a comfor table temperature can be maintained in
the passenger compar tment (air conditioningrunning continuously).On pressing the switch, the engine restar ts
immediately.
To return to normal operation, press the switch
again.
After switching off the ignition, the vehicle will return to normal operation (lamp in the switch off).

*

Except in ZEV mode, which favours electric
running over assuring a comfortable
temperature.
During electric running and when the engine is
stopped, the hybrid system manages restarting
automatically to assure comfor t levels in the
passenger compartment * .
However, variations in temperature may still be felt in very hot climates. To avoid anydiscomfor t in these conditions you can operate
the ECO OFF switch.

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.

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.

Rear foglamps

fixed. The rear foglamps are switched on. Turn the ring on the stalk rear wards to switch off the
rear foglamps.
Warning / indicator lampStateCauseAction / Observations



Diesel engine pre-heating fixed. The STA R T/STOP
switch has been pressed (ignition on). Wait until the warning lamp goes off before star ting.
The period of illumination of the warning lamp is
determined by the ambient conditions (up to about
thirty seconds in extreme conditions).
If the engine does not star t, switch the ignition off and
then on, wait until the warning lamp goes off again,
then start the engine.

Electric parking brake
fixed. The electric parking brake is applied. Release the electric parking brake to switch off the
warning lamp: with your foot on the brake pedal, pull
the electric parking brake control lever.

Obser ve the safety recommendations.
For more information on the electric parking brake,
refer to the corresponding section.

Deactivation of the automatic functions of the electric parkingbrake

fixed. The "automatic application" (on switching off the engine) and
"automatic release" functions aredeactivated or faulty.
Activate the function (according to country) via the
vehicle configuration menu or contact a CITROËN
dealer or a qualified workshop if automatic
application / release is not possible.
The parking brake can be released manually using the emergency release procedure.
For more information on the electric parking brake,
refer to the corresponding section.

With the hybrid system active or when the vehicle is being driven, illumination of one of the following warning lamps indicates a fault which requires action on the par t of the driver.
Any fault resulting in the illumination of a warning lamp must be investigated further by reading the associated message in the instrument panel screen.
If you encounter any problems, contact a CITROËN dealer or a qualified workshop.
