Quality of the fuel used for
Diesel engines

The Diesel engines are perfectly compatible
with biofuels which conform to current andfuture European standards (Diesel fuel which complies with standard EN 590 mixed with a
biofuel which complies with standard EN 14214)
available at the pumps (containing up to 7 %
Fatty Acid Methyl Ester).
The B30 biofuel can be used in cer tain Diesel engines; however, this use is subject to strict
application of the special ser vicing conditions. Contact a CITROËN dealer or a qualified
workshop.
The use of any other type of (bio)fuel(vegetable or animal oils, pure or diluted,
domestic fuel...) is strictly prohibited (risk of
damage to the engine and fuel system).

111Comfort
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 wellas 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 monthto keep it in perfect working order. )
Ensure that the passenger compar tment 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 theoccupants 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 haveit checked regularly as recommended in the ser vicing booklet. )
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 theair 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, firstventilate the passenger compar tment 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 notcontain chlorine and does not present any danger to the ozone layer.


The condensation created by the air conditioning results in a dischargeof water under the vehicle which is
perfectly 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 rear.


When the engine is cold, the air flow will reach its optimum levelprogressively, taking account of the weather and the desired comfort levelso as to avoid too great a distributionof cold air. On entering the vehicle, if the interior temperature is much colder or warmer than the comfort value, there is noneed to change the value displayed in order to obtain the comfor t required.In all seasons, with the windows closedthe system corrects the differencein temperature automatically and asquickly as possible.
This s
ystem 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, except in STOP mode of Stop & Start.

The driver and front passenger can each adjust the temperature to their requirements.
The value indicated on the display corresponds to a level of comfor t and not to a
temperature in degrees Celsius or Fahrenheit.
)Turn control 2or 3to 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 isnormal.
You are advised to avoid a left /right settingdifference of more than 3.

Manual operation

If you wish, you can make a different choice from that offered by the system by changing asetting. The "AUTO"
indicator lamps go off; theother functions, except the air conditioning, willstill be controlled automatically.)
Pressing the "AUTO"
button returns the system to completely automatic operation.
With Stop & Start, when demisting hasbeen switched on, the Diesel engine does not stop.
