2010.5 Citroen DS4 DAG run flat

Monitoring
Manual test in the central colour screen associated with the satellite navigation system
This function allows you to check the status of the vehicle systems (reminder of the "activated"/"deactivated " status of the configurable functions) and to display the aler ts log.
 With the engine running, to star t a manual test, briefly press the ".../000" button on the instrument panel.
The following information appears successively in the instrument panel central colour screen: - engine oil level indicator (see corresponding section),
- ser vice indicator (see corresponding section), - under-inflation detection (if your vehicle
is fitted with this system; see the "Safety" section), - current warnings and aler t messages, if any (see corresponding section for the warning lamp or system concerned), - status of configurable functions (see
"Multifunction screens").
This information also appears every time the ignition is switched on (automatic test).

193Driving
With the engine running and the vehicle stationary, in order to immobilise the vehicle it is essential to manually apply the parking
brake by pulling control lever A .
Immobilising the vehicle,
engine running
The emergency braking must only be used in exceptional circumstances.
Before leaving the vehicle, check that parking brake warning lamp in the instrument panel is on fixed, not flashing.
The application of the parking brake is confirmed by:
- illumination of the braking warning lamp and the P warning lamp in the control lever A ,
- display of the message "Handbrake on".
When the driver’s door is opened, a message is displayed accompanied by an audible signal, if the parking brake has not been applied.
Particular situations
In cer tain situations (e.g. star ting the engine), the parking brake can automatically alter its force. This is normal operation.
To advance your vehicle a few centimetres without star ting the engine, but with the ignition on, press on the brake pedal and release the parking brake by pulling then releasing the control lever A . The full release of the parking brake is confirmed by the warning lamps in the control lever A and in the instrument panel going off and display of the message "Handbrake off ". If the parking brake develops a fault while applied or if the battery runs flat, an emergency release is always possible.
Emergency braking
If a failure of the ESP system is signalled by the illumination of this warning lamp, then braking stability is not guaranteed. In this event, stability must be assured by the driver by repeating alternate "pull-release" actions on the control lever A .
In the event of a failure of the main ser vice brake or in an exceptional situation (e.g. driver taken ill, under instruction, etc) a continuous
pull on the control lever A will stop the vehicle. The electronic stability programme (ESP) provides stability during emergency braking. If the emergency braking malfunctions, the message "Parking brake faulty" will be displayed.

In the event of the electric parking brake malfunctioning or the battery running flat, an emergency manual device can release the parking brake.  Immobilise the vehicle (or keep it stationary, if the brake pedal is pressed), with the engine running, by engaging first gear (manual gearbox) or position M or R(6 -speed electronic gearbox system).
Emergency release
 Switch off the engine but leave the ignition on. If it is not possible to immobilise the vehicle, do not operate the control and contact a CITROËN dealer or a qualified workshop without delay.  Fetch the two vehicle blocks B and the release device C , located under the boot carpet.
 Immobilise the vehicle by placing the blocks in front or behind the two front wheels, opposite to the direction of the slope.  Remove the storage box under the boot carpet for access to the emergency release device.

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.

 Connect the red cable to the positive terminal (+) of the flat battery A , then to the positive terminal (+) of the slave battery B .  Connect one end of the green or black cable to the negative terminal (-) of the slave battery B .  Connect the other end of the green or black cable to the ear th point C on the broken down vehicle.
 Operate the star ter, let the engine run.  Wait until the engine returns to idle and disconnect the cables.
Charging the battery using
a battery charger
The batteries contain harmful substances such as sulphuric acid and lead. They must be disposed of in accordance with regulations and must not, in any circumstances, be discarded with household waste. Take used remote control batteries and vehicle batteries to a special collection point.
 Disconnect the battery from the vehicle.  Follow the instructions for use provided by the manufacturer of the charger. Reconnect starting with the negative terminal (-). Check that the terminals and connectors are clean. If they are covered with sulphate (whitish or greenish deposit), remove them and clean them.
The Stop & Star t battery does not have to be disconnected for charging.
It is advisable to disconnect the battery if the vehicle is to be left unused for
more than one month.
Starting using another
battery

Energy economy mode System which manages the period of use of cer tain functions to conser ve a sufficient level of charge in the battery. After the engine has stopped, you can still use func tions such as the audio equipment, windscreen wipers, dipped beam headlamps, cour tesy lamps, etc. for a maximum combined period of thir ty minutes.
This period may be greatly reduced if the battery is not fully charged.
A flat battery prevents the engine from star ting (refer to the corresponding paragraph).
If the telephone is being used at the same time on the navigation system, it will be interrupted after 10 minutes.
Switching to economy mode
Once this period has elapsed, a message
appears in the screen indicating that the vehicle has switched to economy mode and the active functions are put on standby.
Exiting economy mode
These functions are reactivated automatically
the next time the vehicle is driven.  In order to resume the use of these functions immediately, star t the engine and let it run for a few minutes. The time available to you will then be double the period for which the engine is left running. However, this period will always be between five and thir ty minutes.
