2010.5 Citroen DS4 DAG Owner's Manual

Electric parking brake
This system does not require any routine ser vicing. However, in the event of a problem, have the system checked by a CITROËN dealer or a qualified workshop. For more information, see "Driving - Electric parking brake - § Operating faults".
Only use products recommended by CITROËN or products of equivalent quality and specification. In order to optimise the operation of units as impor tant as the braking system, CITROËN selects and offers very specific products. To avoid damaging the electrical units, the use of a high pressure washer in the engine compar tment is strictly prohibited . Brake disc wear
For information on checking brake disc wear, contact a CITROËN dealer or a qualified workshop.
Manual parking brake
If a loss of effectiveness of this system is noticed, the parking brake must be checked, even between two ser vices. Checking this system must be done by a CITROËN dealer or a qualified workshop.
Brake pads
Brake wear depends on the style of driving, par ticularly in the case of vehicles used in town, over shor t distances. It may be necessary to have the condition of the brakes checked, even between vehicle ser vices. Unless there is a leak in the system, a drop in the brake fluid level indicates that the brake pads are worn.

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.

239Practical information
1. Sealing
 Uncoil the white pipe G fully.  Unscrew the cap from the white pipe.
 Connect the white pipe to the valve of the tyre to be repaired.
Repair procedure
Avoid removing any foreign bodies which have penetrated into the tyre.
 Connect the compressor's electric plug to the vehicle's 12 V socket.
 Star t the vehicle and leave the engine running.
 Switch off the ignition.  Turn the selector A to the "sealant"
position.  Check that the switch B is in position "O" .
Take care, this product is harmful (e.g. ethylene-glycol, colophony...) if swallowed and causes irritation to the eyes. Keep it out of reach of children.

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.

241Practical information
2. Infl ation
 Adjust the pressure using the compressor (to inflate: switch B in position "I" ; to
deflate: switch B in position "O" and press button C ), in accordance with the vehicle's tyre pressure label (located on the left hand door aper ture). A loss of pressure indicates that the puncture has not been fully plugged; contact a CITROËN dealer or qualified
workshop for assistance.  Remove and stow the kit.  Drive at reduced speed (50 mph [80 km/h] max) limiting the distance travelled to approximately 120 miles (200 km).
 Turn the selector A to the "air" position.
 Uncoil the black pipe H fully.  Connect the black pipe to the valve of the wheel.
 Connect the compressor's electric plug to the vehicle's 12 V socket.
 Star t the vehicle again and leave the engine running.
 Visit a CITROËN dealer or a qualified workshop as soon as possible. You must inform the technician that you have used this kit. After inspection, the technician will inform you whether the tyre can be
repaired or must be replaced.

Removing the cartridge
 Stow the black pipe.  Detach the angled base from the white pipe.  Suppor t the compressor ver tically.  Unscrew the car tridge from the bottom.
Checking tyre pressures/
inflating accessories
Beware of discharges of fluid. The expiry date of the fluid is indicated
on the car tridge. The sealant car tridge is designed for single use; even if only par tly used, it must be replaced. After use, do not discard the cartridge into the environment, take it to an authorised waste disposal site or a CITROËN dealer. Do not forget to obtain a new sealant car tridge, available from CITROËN dealers or from a qualified workshop.
You can also use the compressor, without injecting any product, to: - check or adjust the pressure of your tyres, - inflate other accessories (balls, bicycle tyres...).
 Connect the compressor's electrical connector to the vehicle's 12 V socket.  Star t the vehicle and let the engine run.  Adjust the pressure using the compressor (to inflate: switch B in position "I" ; to deflate: switch B in position "O" and press button C ), according to the vehicle's tyre
pressure label or the accessory's pressure label.  Remove the kit then stow it.
 Turn the selector A to the "Air" position.  Uncoil the black pipe H fully.  Connect the black pipe to the valve of the wheel or accessory. If necessary, fit one of the adaptors supplied with the kit first.
