inflation pressure Citroen DS4 2010.5 1.G Owner's Manual

Tyre under-infl ation detection
System which automatically and continuously checks the pressure of the tyres while driving. Sensors fitted in each valve trigger a warning in the event of problem (speed above 12 mph (20 km/h)).
Puncture
The tyre under-inflation detection system is an aid to driving which does not replace the need for the driver to be vigilant or to drive responsibly.
Under-infl ated tyre
This warning lamp is displayed on the instrument panel and/or a message appears in the screen, accompanied by an audible
signal, to identify the wheel concerned.
The STOP warning lamp comes on and/or this warning lamp is displayed on the instrument panel, accompanied by
an audible signal and a message in the screen identifying the wheel concerned.
 Stop as soon as it is safe to do so, avoiding any sudden movement of the steering wheel and the brakes.  Repair or change the damaged wheel (punctured or very deflated tyre), and have the tyre pressure checked as soon as possible.
 Check the tyre pressures as soon as possible. This check must be carried out when the tyres are cold.

173Safety
Sensor(s) not detected or faulty
A message appears in the screen, accompanied by an audible signal, to identify the wheel or wheels which are not detected or
to indicate a fault in the system. Contact a CITROËN dealer or a qualified workshop to replace the faulty sensor(s).
All repairs and changing of tyres on a wheel fitted with this system must be carried out by a CITROËN dealer or a qualified workshop.
If, when changing a tyre, you install a wheel which is not detected by your vehicle (example: fitting of snow tyres), you must have the system reinitialised by a CITROËN dealer or a qualified workshop.
This system does not avoid the need to have the tyre pressures checked regularly (refer to the "Identification markings" section) to ensure that
the optimum dynamic per formance of the vehicle is maintained and prevent premature wear of the tyres, par ticularly in arduous driving conditions (heavy load, high speed). The tyre pressures must be checked cold, at least once a month. Remember to check the pressure of the spare wheel. The tyre under-inflation detection system may experience temporary inter ference due to electro-magnetic emissions on a frequency close to that used by the system.
This message is also displayed when one of the wheels is away from the vehicle (being repaired) or when one or more wheels without a sensor are fitted. If your vehicle is equipped with a spare
wheel, this is not fitted with a sensor.

Temporary puncture repair kit
and a sealant car tridge which permits temporar y repair of a tyre so that you can pairdrive to the nearest garage. It is designed to repair most punctures which
could affect the tyre, located on the tyre tread or shoulder.
Access to the kit
The speed limit sticker I must be affixed to the vehicle's steering wheel to remind you that a wheel is in temporary use. Do not exceed a speed of 50 mph (80 km/h) when driving with a tyre repaired using this type of kit.
Description of the kit
A. "Sealant" or "Air" position selector. B. On "I" /off "O" switch. C. Deflation button. D. Pressure gauge (in bar or p.s.i.). E. Compar tment housing: - a cable with adaptor for 12 V socket, - various inflation adaptors for accessories, such as balls, bicycle tyres...
F. Sealant car tridge. G. White pipe with cap for repair. H. Black pipe for inflation. I. Speed limit sticker.
This kit is installed in the storage box, under the boot floor.

Switch on the compressor by moving the switch B to position "I" until the tyre
pressure reaches 2.0 bars. The sealant is injected into the tyre under pressure; do not disconnect the pipe from the valve during this operation (risk of splashing).
 Remove the kit and screw the cap back on the white pipe.
Take care to avoid staining your vehicle with traces of fluid. Keep the kit to hand.  Drive immediately for approximately three miles (five kilometres), at reduced speed (between 15 and 35 mph [20 and 60 km/h]), to plug the puncture.  Stop to check the repair and the tyre
pressure using the kit.
If after around 5 to 7 minutes the pressure is not attained, this indicates that the tyre is not repairable; contact a CITROËN dealer or a qualified workshop for assistance.
Tyre under-infl ation detection
If the vehicle is fitted with tyre under-inflation detection, the under-inflation warning lamp will remain on after the wheel has been repaired until the system is reinitialised by a CITROËN dealer or a qualified workshop.

281Technical data

Identifi cation markings
Various visible markings for the identification of yo ur vehicle.
A. Vehicle identification number (VIN) under the bonnet. This number is engraved on the bodywork near the engine mounting.
B. Vehicle identification number on the dashboard. This number is indicated on a self-adhesive label which is visible through the windscreen.
D. Tyre/paint label. This label is affixed to the driver's front pillar.
Wheels which are fitted with 225/40 R18 tyres cannot be fitted with snow chains. For more information, contact a CITROËN dealer or a qualified workshop.
Low tyre pressures increase fuel consumption.
The tyre pressures must be checked
when the tyres are cold, at least once a month.
C. Manufacturer's label. The VIN is indicated on a self-destroying label affixed to the driver's centre pillar.
It bears the following information: - the tyre pressures, for unladen and laden conditions, - the wheel rim and tyre sizes, - the brands of tyre recommended by the manufacturer, - the spare tyre inflation pressure, - the paint colour code.
