2012 Citroen DS4 maintenance

35
Limit the causes of excess
consumption
Spread loads throughout the vehicle; placethe heaviest items in the bottom of the boot, as close as possible to the rear seats. Limit the loads carried in the vehicle andreduce wind resistance (roof bars, roof rack,bicycle carrier, trailer...). Use a roof box in preference. Remove roof bars and roof racks after use.


At the end of winter, remove snow tyres andrefit your summer tyres.



Observe the recommendations
on maintenance


Check the tyre pressures regularly, whencold, referring to the label in the door aperture, driver's side.
Carry out this check in par ticular:


- before a long journey,

- at each change of season,

- after a long period out of use.
Don't forget the spare wheel and the tyres on any trailer or caravan.


Have your vehicle ser viced regularly (engineoil, oil filter, air filter...) and obser ve theschedule of operations recommended by the manufacturer.




When refuelling, do not continue after the 3 rdcut-off of the nozzle to avoid any overflow.

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 settledown to a consistent average.
Switch off the headlamps and front foglamps when the level of light does not require their use.

Avoid running the engine before moving off,particularly in winter; your vehicle will warmup much faster while driving.

As a passenger, if you avoid connecting your multimedia devices (film, music, videogame...), you will contribute towards limitingthe consumption of electrical energy, and soof fuel. Disconnect your por table devices beforeleaving the vehicle.

Recommendations for ventilation and air conditioning


If after an extended stop in sunshine, the interior temperature is veryhigh, 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 notcontain chlorine and does not present any danger to the ozone layer.

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 per fect 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.
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.


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




Stop & Start
The heating and air conditioning systems only work when the engine is running. To maintaina comfor table temperature in the passenger compartment, you can temporarily deactivatethe Stop & Start system (see "Driving").

toaccelerate.
When the engine is running at idle, withthe brakes released, if position R, Dor Mis selected, the vehicle moves even without the accelerator being pressed. When the engine is running, never leave children in the vehicle withoutsupervision. When carrying out maintenance withthe engine running, apply the parking brake and select position P.P


Automatic operation
)Select position D
for automatic
changing
of the six gears.
The gearbox then operates in auto-adaptive mode, without any inter vention on the par t
of the driver. It continuously selects the most suitable gear according to the style of driving,
the profile of the road and the load in the
vehicle.
For maximum acceleration without touching
the lever, press the accelerator pedal down fully (kick down). The gearbox changes down
automatically or maintains the gear selected
until the maximum engine speed is reached.
On braking, the gearbox changes down
automatically to provide efficient enginebraking.
If you release the accelerator sharply, the
gearbox will not change to a higher gear for safety reasons.

Never select position Nwhile thevehicle is moving. Never select positions Por R
unless the vehicle is completely stationary.

The system is reactivated automaticallyat every new star t using the key.
Reactivation

This system requires a specific battery with aspecial specification and technology (reference numbers available from a CITROËN dealer or a qualified workshop).
Fitting a battery not listed by CITROËN
introduces the risk of malfunction of the system. In the event of a malfunction with the s
ystem,
the "ECO OFF"switch warning lamp flashes,
then comes on continuously.
Have it checked by a CITROËN dealer or aqualified workshop.


Operating fault
Maintenance

Before doing anything under the bonnet, deactivate the Stop & Start system to avoid any risk of injury resulting from automatic operation of STA R T mode.

The Stop & Star t system makes use of advanced technology. All work on this type of battery must be done only by a CITROËN dealer or a qualifiedworkshop. Pr
ess the "ECO OFF"switch again.
The system is active again; this is confirmed
by the switch warning lamp going off and the
display of a message.
In the event of a fault in STOP mode, thevehicle may stall. All of the instrumentpanel warning lamps come on.Depending on version, an alert message may also be displayed askingyou to put the gear lever into position Nand put your foot on the brake pedal.
It is then necessary to switch off the ignition, then restart the engine using the key.
