2014 Citroen DS5 HYBRID4 RHD Owner's Manual

47Hybrid system
Eco-driving
Eco-driving is a range of everyday practices that allow the motorist to optimise their fuel consumption and CO2 emissions.
Eco-driving suited to your
Hybrid4 vehicle
Use gear selector position A , as this optimises gear changes to suit the circumstances, and the AUTO mode of the Hybrid4 mode selector. When moving off, accelerate normally up to the desired speed ( POWER zone between 20 and 40 %). At steady speeds, drive gently with small movements of the accelerator pedal ( ECO or CHARGE zone), run in electric mode as often as possible when driving at low speed. Anticipate the need to slow down and use engine braking ( CHARGE zone), so as to make use of free energy recovery while keeping light pressure on the accelerator pedal.
Before moving off, if the passenger compartment is too warm, ventilate it by opening the windows and air vents before using the air conditioning. Above 30 mph (50 km/h), close the windows and leave the air vents open. Remember to make use of equipment that can help keep the temperature in the passenger compartment down (sun roof and window blinds...). Switch off the air conditioning, unless it has automatic digital regulation, as soon as the desired temperature is attained. Switch off the demisting and defrosting controls, if not automatic. Switch off the heated seat as soon as possible.
Switch off the headlamps and front foglamps when the level of light does not require their use.
Avoid running the Diesel engine when stationary, particularly in winter; your vehicle will warm up much faster while driving.
As a passenger, if you avoid connecting your multimedia devices (film, music, video game...), you will contribute towards limiting the consumption of electrical energy, and so of fuel. Disconnect your portable devices before leaving the vehicle.
Control the use of your electrical equipment

Observe the recommendations
on maintenance
Check the tyre pressures regularly, when cold, referring to the label in the door aperture, driver's side. Carry out this check in particular: - before a long journey, - at each change of season, - after a long period out of use.
Have your vehicle serviced regularly (engine oil, oil filter, air filter, passenger compartment filter...) and observe the schedule of operations recommended in the maintenance and warranty guide.
When refuelling, do not continue after the 3 rd cut-off of the nozzle to avoid any over flow.
At the wheel of your new vehicle, it is only after the first 1 800 miles (3 000 kilometres) that you will see the fuel consumption settle down to a consistent average.
At the end of winter, remove snow tyres and refit your summer tyres.
Spread loads throughout the vehicle; place the heaviest items in the bottom of the boot, as close as possible to the rear seats. Limit the loads carried in the vehicle and reduce wind resistance (roof bars, roof rack, bicycle carrier, trailer...). Use a roof box in preference. Remove roof bars and roof racks after use.
Limit the causes of excess
consumption

49Hybrid system
Consumption of your hybrid in the screen
Average consumption over the last 5 minutes.
"60 % Hybrid 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 be recharged 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 converts 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 alternator-starter motor (Stop & Start) of the Diesel engine.
This recovery allows the use of "free" energy. The battery charging time is very short and is continuous. 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 charging takes place automatically when driving . The energy recovery can be faster during deceleration. 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 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 may overheat, damaging the battery and causing a loss of per formance of the hybrid system.

Fan cooling of the high voltage battery
For the best use of the high voltage battery, please follow these recommendations: - do not obstruct the air intake with loose articles, otherwise, the battery may overheat, causing a loss of per formance of the hybrid system - 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 left hand boot trim panel).

The high voltage battery must not in any circumstances be charged from an external source and must only be handled by a workshop technician. 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 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 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 ( Ready lamp off).
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.

Underbonnet precautions / warnings
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 time.
Always ensure that the ignition is switched off ( Ready lamp off) before opening the bonnet.
Before doing anything under the bonnet, to avoid the risk of serious injury switch off the ignition and verify that the Ready lamp in the dashboard is off. Also ensure that the ignition is switched off when refuelling to avoid the engine restarting.

Car washing machine or tunnel
Some car washing machines or tunnels (where the vehicle is moved for wards on a travelling track) require that the parking brake be "released" during the wash.
With the hybrid system active, Ready lamp on, parking brake released: - Place the gear selector in position N . - Switch off the engine (press on START/STOP). The parking brake is applied automatically and the Ready lamp goes off in the 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 the centre console, while keeping your foot on the brake pedal. - Switch off the ignition (press on START/STOP without your foot on the brake pedal) checking that the parking brake
remains released.
If the Diesel engine is not running, it restarts. If the Diesel engine is running, it remains running without time limit.
With the hybrid system active, Ready lamp on, parking brake released: - Place the gear selector in position N (Auto or Sport mode). - Press the brake pedal then the ECO OFF button.
