2013.5 Citroen DS5 HYBRID4 RHD air filter

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).

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.

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

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.

The various caps and covers allow access for checking the levels of the various fluids, for replacing certain components and for priming the fuel system.

Particle emission filter (Diesel)
The start of saturation of the particle filter is indicated by the temporary illumination of this warning lamp accompanied by a message in the multi-function screen. As soon as the traffic conditions permit, regenerate the filter by driving at a speed of at least 40 mph (60 km/h) until the warning lamp goes off. If the warning lamp stays on, this indicates a low additive level.
On a new vehicle, the first particle filter regeneration operations may be accompanied by a "burning" smell, which is per fectly normal. Following prolonged operation of the
vehicle at very low speed or at idle, you may, in exceptional circumstances, notice the emission of water vapour at the exhaust on acceleration. This does not affect the behaviour of the vehicle or the environment.
The 100% electric mode is not available during regeneration of the particle emissions filter.

Oil filter
Replace the oil filter each time the
engine oil is changed. Refer to the maintenance and warranty guide for details of the replacement interval for this component.
Refer to the maintenance and warranty guide for details of the replacement intervals for these components.
Depending on the environment (e.g. dusty atmosphere) and the use of the vehicle (e.g. city driving), replace them twice as often if necessary . necessary . necessary A clogged passenger compartment filter may have an adverse effect on the per formance of the air conditioning system and generate undesirable odours.
