2010.5 Citroen DS4 DAG warning

221Driving
Front parking sensors Operating fault
If an operating fault occurs, when reverse gear is engaged this warning lamp is displayed in the
instrument panel and/or a message appears in the screen, accompanied by an audible signal (shor t beep). Contact a CITROËN dealer or a qualified workshop.
In addition to the rear parking sensors, the front parking sensors are triggered when an obstacle is detected in front and the speed of the vehicle
is still below 6 mph (10 km/h). The sound emitted by the speaker (front or rear) indicates whether the obstacle is in front or behind. The front parking sensors are interrupted if the vehicle stops for more than three seconds in for ward gear, if no fur ther obstacles are detected or when the speed of the vehicle exceeds 6 mph (10 km/h).
The function will be deactivated automatically if a trailer is being towed or a bicycle carrier is fitted (vehicle fitted with a towbar or bicycle carrier recommended by CITROËN).
In bad weather or in winter, ensure that the sensors are not covered with mud, ice or snow. When reverse gear is engaged, an audible signal (long beep) indicates that the sensors may be dir ty. When the vehicle is moving at a speed below 6 mph (10 km/h), cer tain sound sources (motorcycle, lorry, pneumatic drill, etc.) may trigger the audible signals of the parking sensor system.
Deactivation/Activation of the front and rear parking sensors
The function is deactivated by pressing this button. The indicator lamp in the button
comes on. Pressing this button again reactivates the function. The indicator lamp in the button goes off.

Topping up
The reser voir must be topped up without delay by a CITROËN dealer or a qualified workshop.
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 or a qualified workshop (France) or to an authorised waste disposal site.
 Open the bonnet and secure it with the stay.  Open the screenwash reser voir filler cap.  Take and pinch the level gauge to block its breather.  Remove the gauge completely from the reser voir to read the level in the transparent section.  Top up if necessary.  Refit the filler cap to the reser voir and close the bonnet.
Specifi cation of the fl uid
To ensure optimum cleaning and to avoid freezing, the fluid should never be topped up or replaced by plain water.
According to your version of instrument panel, the additive reser voir low level is indicated by:
- fixed illumination of the particle emissions filter warning lamp, accompanied by an audible signal and a message that the particle emissions filter additive level is too low,
or
- fixed illumination of the ser vice warning lamp, accompanied by

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.
Manual gearbox
The gearbox does not require any maintenance (no oil change). Refer to the Warranty and Maintenance Record for the details of the level checking inter val for this component.
According to your version of instrument panel, the start of saturation of the particle emissions filter is indicated by:
6-speed electronic gear
control gearbox
The gearbox does not require any maintenance (no oil change).
Refer to the Warranty and Maintenance Record for details of the checking inter val for this component.
- temporary illumination of the service warning lamp, accompanied
by an audible signal and a message that there is a risk of blockage of the particle emissions filter.
- fixed illumination of the particle emissions filter warning lamp, accompanied by an audible signal and a message that there is a risk of blockage of the particle emissions filter,
or
As soon as the traffic conditions permit, regenerate the filter by driving at a speed of at least 40 mph (60 km/h) until the warning lamp
goes off. If the warning lamp stays on, refer to the "Additive level" section.

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.

Removing a wheel
Parking the vehicle
Immobilise the vehicle where it does not block traffic: the ground must be level, stable and non-slippery ground. Apply the parking brake unless it has been programmed to automatic mode, switch off the ignition and engage first gear * to lock the wheels. Check that the braking warning lamps in the instrument panel are on (not flashing). If necessary, place a chock under the wheel diagonally opposite the wheel to be changed. The occupants must get out of the vehicle and wait where they are safe. Never go underneath a vehicle raised using a jack; use an axle stand.
