For economical driving, caring for the environment
The fuel consumption of a vehicle varies greatly : - according to the driver's style of driving (moderate, aggressive, fast, ...), - according to the type of journeys made (urban, main road, motor way, flowing, heavy traffic, …) and the speed.
Main recommendations for driving economically
Hybrid mode selector
To optimise fuel consumption, use the Auto mode of the selector whenever possible (the mode is activated automatically when starting) including for urban journeys. This mode optimises the use of the energy sources (internal combustion engine and/or electric) contrary to other modes, which are for use in particular cases.
Gear lever
Use the automatic mode A as much as possible as this optimises gear changes to suit the requirements.
Causes of high consumption and checks
As with any vehicle, limit overloading, wind resistance (windows open above 30 mph (50 km/h), roof bars, loaded or not, …), the use of power consumers (air conditioning, heated seats, heated rear screen, …). Observe the recommendations on checks (regular check of tyre pressures, correct tyre pressures, …) and routine servicing.
Drive smoothly
Stay in the "eco" zone displayed in the energy consumption / generation indicator: accelerate gently, drive at steady speeds using the speed limiter or cruise control as soon as possible. Use the "charge"zone: anticipate the need to slow down by taking your foot off the accelerator rather than braking. The movement of the energy consumption / generation indicator needle (into the "charge" zone), shows the level of energy recovery.
Consumption history
See the impact of your style of driving and the type of journey by reviewing the history of your energy consumption. Refer to the "Multifunction screens" section.

Automatic restarting of the Diesel engine or ZEV mode NOT available
Maintaining the performance of the system
- When the vehicle exceeds 18 mph (30 km/h) after moving off (if the internal
combustion engine has not already started since the vehicle was last started). - If the high voltage battery is not sufficiently charged. A minimum of 4 bars in ZEV mode so as to ensure operation over a certain distance (in AUTO, electric operation is accessible for a shorter period with a lower level of charge). - When the fuel level enters the reserve zone (where rate of consumption of this reserve is high, ZEV inhibition may continue for some time after refuelling). - During regeneration of the particle emissions filter, which occurs automatically for 5 to 10 minutes, approximately every 300 miles (500 kms) (or less in extended urban running).
The internal combustion engine may restart or ZEV mode may not be available in the various conditions presented below. The internal combustion engine can be switched off automatically as soon as these conditions are lifted. When the conditions described below cause the vehicle to come out of ZEV mode and the Diesel engine to restart, the vehicle automatically changes to AUTO mode.
Your vehicle is fitted with the most effective emissions control systems, in particular the Particle Emissions Filter (PEF). At regular intervals your Diesel engine will produce energy for the self-cleaning of this f i l t e r. During this PEF regeneration phase, electric running is purposely made unavailable and is accompanied by a message " Electric mode not available: PEF regeneration in progress ".
Action by the driver
- Moving the gear selector to position M . - Action on steering mounted control paddles to change gear. - Sustained and sharp acceleration. - Use of demisting. - Use of air conditioning.
Diffi cult weather conditions and circumstances
- If certain conditions or engine temperature requirements make it necessary (such as an engine temperature that is too low for the ambient conditions). - When the battery is close to maximum charge (for example: when going down a long hill), because engine recovery being no longer possible, the internal combustion engine restarts automatically just to provide engine braking. - If the vehicle encounters a steep slope (car park ramp, ...). - If the vehicle has been parked in the sun for a prolonged period. - When driving in mountainous conditions (altitude).

Hybrid4 frequently asked questions
ZEV (Zero Emissions Vehicle) mode
QuestionAnswer
Why is it not always possible for me to put the vehicle into ZEV (Zero Emissions Vehicle) mode even though the battery is well charged?
This situation is temporary. Certain conditions will occasionally prevent the change to ZEV mode, even if the battery has sufficient charge, such as, for example, very cold conditions, altitude, demisting, high demand for heating or air conditioning, regeneration of the particle emissions filter (PEF).
Why do I sometimes see an alert message "Electric mode not available: PEF regeneration in progress"?
This is an message relating to the regeneration of the particle emissions filter (PEF). This is a completely normal process that takes place every 240 or 300 miles (400 or 500 km) (or more frequently in prolonged urban use), as on a conventional HDi vehicle. This process is not generally noticed by the driver. On the other hand, in the case of a hybrid, this phenomenon may be noticeable (in urban use) as temporarily the HDi engine will not stop and this message will be displayed at intervals while regeneration is in progress.
Why is it not possible for me to put the vehicle into ZEV mode, even though I had just been running electrically in Auto mode?
The management of ZEV is different from Auto mode. Changing to ZEV mode is only possible with a battery charge of at least 4 bars, in order to assure sufficient range. In Auto mode, the system alone manages the conditions for changing temporarily to electric mode, for shorter periods and with a lower state of charge of the battery.
Why is the range in ZEV (Zero Emissions Vehicle) mode lower when climbing? The vehicle needs more energy when climbing than when running on the level. So it is better to stay in Auto mode, which will favour operation of the Diesel engine.
Why is it that the system makes me come out of ZEV (Zero Emissions Vehicle) mode; it does not return to ZEV automatically when the conditions
allow?
It is not intended to give preference to ZEV running at any cost, as it is not always the most economical mode. So the system returns automatically to Auto mode.

Air conditioning
QuestionAnswer
It seems to me that the vehicle runs less on electric when the heating or air conditioning is operating, is that right?
The demand for heating or air conditioning may require the starting of the Diesel engine until the desired level of comfort is attained. Normal hybrid operation is simply put back. The period can be longer under low or very high ambient temperatures.
It seems to me that when it is very hot and the air conditioning is working, the vehicle runs on electric for shorter periods. Is that right?
When it is hot, the periods when the Diesel engine is put on standby and the vehicle runs on electric are necessarily restricted in order to limit the difference between the temperature in the vehicle and the level of comfort selected. In very hot weather, it is always possible to press the Eco OFF button (which brings the vehicle out of ZEV mode and prevents electric running or the stopping of the engine) to give preference to temperature control (keeps the air conditioning running).
Special Hybrid4 features
QuestionAnswer
Can I tow with my hybrid vehicle and how much? A Hybrid4 vehicle can tow between 500 kg and 800 kg (see the "Towing" section). This allows a jet ski or two-wheeler on a trailer to be towed, for example. The "technical" reason for the limit is related to maintaining adequate cooling capacity for the internal combustion engine as well as the hybrid components that are also cooled by the engine's cooling system.
Why does engine braking seem so strong? When you take your foot off the accelerator, the engine braking results mainly from the energy recovery by the electric motor. This leads to a higher level of deceleration than a conventional vehicle and so allows the recovery of free energy.

DS5-HYBRID_EN_CHAP00C_HYBRIDE_ED02-2013
ECO OFF switch
This function prevents the Diesel engine being switched off and so ensures that a comfortable temperature can be maintained in the passenger compartment (air conditioning running continuously). On pressing the switch, the engine restarts
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 comfort levels in the passenger compartment * . However, variations in temperature may still be felt in very hot climates. To avoid any discomfort in these conditions you can operate the ECO OFF switch.

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.

In order for these systems to be fully effective, follow the operation and maintenance guidelines below:  To obtain an even air distribution, take care not to obstruct the exterior air intake grilles located at the base of the windscreen, the nozzles, the vents and the air outlets, as well as the air extractor located in the boot.  Do not cover the sunshine sensor, located on the dashboard; this is used for regulation of the digital air conditioning system.  Operate the air conditioning system for at least 5 to 10 minutes, once or twice a month to keep it in per fect working order.  Ensure that the passenger compartment filter is in good condition and have the filter elements replaced regularly (refer to the "Checks" section). We recommend the use of a combined passenger compartment filter. Thanks to its special active additive, it contributes to the purification of the air breathed by the occupants and the cleanliness of the passenger compartment (reduction of allergic symptoms, bad odours and greasy deposits).  To ensure correct operation of the air conditioning system, you are also advised to have it checked regularly as recommended in the maintenance and warranty guide.  If the system does not produce cold air, switch it off and contact a CITROËN dealer or a qualified workshop. You can switch off the air conditioning (AC button) and stay in Automatic mode in order to limit fuel consumption. If misting appears while in this mode, you can switch the air conditioning back on temporarily to improve the situation. When towing the maximum load on a steep gradient in high temperatures, switching off the air conditioning increases the available engine power and so improves the towing ability.
Recommendations for ventilation and air conditioning
If after an extended stop in sunshine, the interior temperature is very high, first ventilate the passenger compartment for a few moments. Put the air flow control at a setting high enough to quickly change the air in the passenger compartment. The air conditioning system does not contain chlorine and does not present any danger to the ozone layer.
The condensation created by the air conditioning results in a discharge of water under the vehicle which is per fectly normal.

Dual-zone digital air conditioning
1. Automatic comfort programme
We recommend the use of one of the three AUTO modes available: they provide optimised regulation of the temperature in the passenger compartment according to the comfort value that you have chosen. These three modes automatically control the system, according to the desired setting, while also maintaining the desired comfort value.
 Press the "AUTO" button repeatedly: - a first indicator lamp comes on; the "low" setting mode is selected, - a second indicator lamp comes on; the "medium" setting mode is selected, - a third indicator lamp comes on; the "high" mode setting is selected. Use the "medium" and "high" settings in preference to maintain the comfort level at the r e a r.
When the engine is cold, the air flow will reach its optimum level progressively, taking account of the weather and the desired comfort level so as to avoid too great a distribution of cold air. On entering the vehicle, if the interior temperature is much colder or warmer than the comfort value, there is no need to change the value displayed in order to obtain the comfort required. In all seasons, with the windows closed the system corrects the difference in temperature automatically and as quickly as possible.
This system is designed to operate effectively
in all seasons, with the windows closed.
Automatic operation
The air conditioning can only operate when the hybrid system is active (Ready lamp on). Its effectiveness will be reduced when in electric mode (see the ECO OFF section).
