DS5-HYBRID_EN_CHAP03_CONFORT_ED02-2013
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).

4. Automatic visibility programme
For maximum cooling or heating of the passenger compartment, it is possible to exceed the minimum value 14 or the maximum value 28.  Turn control 2 or 3 to the left until "LO" is displayed or to the right until "HI" is displayed.
See "Front demisting - defrosting".
2-3. Driver's-passenger's side settings
The driver and front passenger can each adjust the temperature to their requirements. The value indicated on the display corresponds to a level of comfort and not to a temperature in degrees Celsius or Fahrenheit.
 Turn control 2 or 3 to the left or to the right respectively to decrease or increase this value.
A setting around the value 21 provides optimum comfort. However, depending on your requirements, a setting between 18 and 24 is normal. You are advised to avoid a left / right setting difference of more than 3.
Manual operation
If you wish, you can make a different choice from that offered by the system by changing a setting. The "AUTO" indicator lamps go off; the other functions, except the air conditioning, will still be controlled automatically.  Pressing the "AUTO" button returns the system to completely automatic operation.
With Stop & Start, when demisting has been switched on, the Diesel engine does not stop.

5. Air conditioning On / Off
 Press this button to switch off the air conditioning.
Switching the system off could result in discomfort (humidity, condensation).  Press this button again to return to automatic operation of the air conditioning. The indicator lamp in the "A /C " button comes on. To obtain cool air more quickly, you can use recirculation of the interior air for a few moments. Then revert to the intake of exterior a i r.
6. Air distribution adjustment
 Press one or more buttons to direct the air flow towards:
- the windscreen and side windows, - the outer and centre air vents, - the footwells. You can combine the three orientations to obtain the desired air distribution.
7. Air fl ow adjustment
 Turn this control to the left to decrease the air flow or to the right to increase the air flow.
The air flow indicator lamps, between the two fans, come on progressively in relation to the value requested.
8. Air intake / Air recirculation
Air recirculation enables the passenger compartment to be isolated from exterior odours and smoke when external pollution is detected (if your vehicle is fitted with a pollution sensor).
It is activated automatically on operation of the screenwash. It is inactive when the ambient temperature is below 5 °C to avoid the risk of misting in the vehicle.
- The indicator lamp with "A" on indicates that recirculation is controlled automatically. - The indicator lamp without "A" on indicates that recirculation is forced manually. - Both indicator lamps off indicates that recirculation is controlled automatically without taking account of the detection of pollution.
Without pollution sensor
If your vehicle is not fitted with a pollution sensor, press this button to force recirculation manually.
In ZEV mode, the hybrid system may temporarily inhibit operation of the air conditioning.
The ZEV mode gives preference to electric driving rather than maintaining a comfortable temperature.

241Practical information
DS5-HYBRID_EN_CHAP08_INFO PRATIQUES_ED02-2013
System which manages the duration of use of certain functions to conserve a sufficient level of charge in the battery. After the engine has stopped, you can still use functions such as the audio and telematics system, windscreen wipers, dipped beam headlamps, courtesy lamps, etc. for a maximum combined duration of about forty minutes.
Energy economy mode
Switching to economy mode
A message then appears in the instrument panel screen indicating that the vehicle has switched to economy mode and the active functions are put on standby. If a telephone call is being made at this time, it
will be maintained for around 10 minutes with the Bluetooth hands-free system of your audio system.
Exiting economy mode
These functions are reactivated automatically next time the vehicle is driven. In order to restore the use of these functions immediately, start the engine and let it run: - for less than ten minutes, to use the equipment for approximately five minutes, - for more than ten minutes, to use the equipment for up to approximately thirty minutes. Let the engine run for the duration specified to ensure that the battery charge is sufficient. Do not repeatedly and continuously restart the engine in order to charge the battery. A flat battery prevents the engine from starting (refer to the "Battery" section).
In this energy economy mode and when starting up the hybrid system, it may take a few seconds before the Readylamp comes on.
Load reduction mode
System which manages the use of certain functions according to the level of charge remaining in the battery. When the vehicle is being driven, the load reduction function temporarily deactivates certain functions, such as the air conditioning, the heated rear screen... The deactivated functions are reactivated automatically as soon as conditions permit.

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.
