2010 Citroen DS3 DAG Owner's Manual

Changing the coolant
The coolant does not have to be changed.
Fluid specifi cation
The coolant must conform to the manufacturer's recommendations.
Screenwash fluid level
Fluid specifi cation
For optimum cleaning and to avoid freezing, this fluid must not be topped up or replaced with water.
Take care when carrying out checks under the bonnet as some par ts of the engine can be very hot (risk of burns).
Coolant level
Top up the level when necessary.
The coolant level should be close to the "MA X" mark but should never exceed it. When the engine is warm, the temperature of the coolant is regulated by the fan. This can operate with the ignition off. On vehicles which are fitted with a par ticle emission filter, the fan may operate after the vehicle has been switched off, even if the engine is cold.
In addition, as the cooling system is pressurised, wait at least one hour after switching off the engine before carrying out any work. To avoid any risk of scalding, unscrew the cap
by two turns to allow the pressure to drop. When the pressure has dropped, remove the cap and top up the level.

171Checks
Diesel additive level
(Diesel engine with particle
emission filter)
A low additive level is indicated by lighting of the ser vice warning lamp, accompanied by an audible warning and a message on the multifunction screen.
Topping up
This additive must be topped up by a CITROËN
dealer without delay.
Used products
Avoid prolonged contact of used oil or fluids with the skin. Most of these fluids are harmful to health or indeed very corrosive.
Do not discard used oil or fluids into sewers or onto the ground. Take used oil to a CITROËN dealer (France) or an authorised waste disposal site.

Checks
Battery Air filter and passenger compartment filter
Oil filter
Particle emission filter (Diesel)
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.
Unless other wise indicated, check these components in accordance with the Maintenance and Warranty Guide and according to your engine. Other wise, have them checked by a CITROËN dealer.
The battery does not require any maintenance. However, check that the terminals are clean and correctly tightened, particularly in summer and winter. When carrying out work on the battery, refer to the "Practical information" section for details of the precautions to be taken before disconnecting the battery and following its reconnection.
Refer to the Maintenance and Warranty Guide for details of the replacement inter vals for these components. Depending on the environment (e.g. dusty atmosphere) and the use of the vehicle (e.g. city driving), replace them twice as often if necessar y (refer to the "Engines" section). A clogged passenger compar tment filter may have an adverse effect on the per formance of the air conditioning system and generate undesirable odours.
Replace the oil filter each time the engine oil is changed.
Refer to the Maintenance and Warranty Guide for details of the replacement inter val for this component.
The presence of this label, in par ticular with the Stop & Star t system, indicates the use of a specific 12 V lead-acid battery with special technology and specification, for which the involvement of a CITROËN dealer is required when replacing or disconnecting the battery. Failure to obser ve this recommendation may cause premature wear of the battery.
It is imperative that the maintenance of the par ticle emission filter is carried out by a CITROËN dealer.

173Checks
Manual gearbox
Automatic gearbox
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 circuit, a drop in the brake fluid level indicates that the brake pads are worn.
The gearbox does not require any maintenance (no oil change). Refer to the Maintenance and Warranty Guide for the details of the level checking inter val for this component.
Brake disc wear
Parking brake
If a loss of effectiveness of this system is noticed, the parking brake must be checked, even between two ser vices. This system must be checked by a CITROËN dealer.
Only use products recommended by CITROËN or products of equivalent
quality and specifications. 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 .
The gearbox does not require any maintenance (no oil change).
Refer to the Maintenance and Warranty Guide for details of the level checking inter val for this component.
For information relating to checking the brake disc wear, contact a
CITROËN dealer.

Temporary puncture repair kit
and a sealant car tridge which permits temporar y repair of the 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.

177Practical 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 for assistance.

179Practical 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 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 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.
