2010.5 Citroen DS4 brake light

Braking assistance systems
Group of supplementary systems which help you to obtain optimum braking in complete safety in emergency situations: - anti-lock braking system (ABS), - electronic brake force distribution (EBFD), - emergency braking assistance (EBA).
Anti-lock braking system
and electronic brake force
distribution
Linked systems which improve the stability and manoeuvrability of your vehicle when braking, in par ticular on poor or slippery sur faces.
Activation
The anti-lock braking system comes into operation automatically when there is a risk of wheel lock. Normal operation of the ABS may make itself felt by slight vibration of the brake pedal.
When braking in an emergency, press very firmly without releasing the pressure.
Operating fault
If this warning lamp comes on, together with the STOP and ABSwarning lamps, accompanied by an audible signal and a message in the multifunction screen, it indicates a malfunction of the electronic brake force distribution which could result in loss of control of the vehicle when braking. You must stop as soon as it is safe to do so.
When replacing wheels (tyres and rims), ensure that they conform to the manufacturer's recommendations.
If this warning lamp comes on, accompanied by an audible signal and a message in the multifunction screen, it indicates a malfunction of the anti-lock braking system which could result in loss of control of the vehicle when braking.
In either case, contact a CITROËN dealer or a qualified workshop.

Stop & Start The Stop & Star t system puts the engine temporarily on standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...). The engine restar ts automatically - START mode - as soon as y ou want to move off. The restar t takes place instantly, quickly and silently. Per fect for urban use, the Stop & Star t system reduce s fuel consumption and exhaust emissions as well as the noise level when stationary.
Operation
Going into engine STOP mode
With the automatic gearbox system, for your comfor t during parking maoeuvres, STOP mode is not available for a few seconds after coming out of reverse gear. STOP mode does not affect the functionality of the vehicle, such as braking, power steering, for example.
Never refuel with the engine in STOP mode; you must switch off the ignition with the key.
The "ECO" warning lamp comes on in the instrument panel and the engine goes into standby:
- with a manual gearbox , at speeds below 12 mph (20 km/h), when you put the gear lever into neutral and release the clutch pedal, - with the 6-speed electronic gearbox system , at a speed below 5 mph (8 km/h),
when you press the brake pedal or put the gear lever into position N .
If your vehicle is fitted with the system, a time counter calculates the sum of the periods in STOP mode during a journey. It resets itself to zero every time the ignition is switched on with the key.
STOP mode is not invoked when: - the driver's door is open, - the driver's seat belt is not fastened, - the vehicle has not exceeded 6 mph (10 km/h) since the last engine start using the key, - the electric parking brake is applied or being applied, - the engine is needed to maintain a comfor table temperature in the passenger compar tment, - demisting is active, - some special conditions (battery charge, engine temperature, braking assistance, ambient temperature...) where the engine is needed to assure control of a system.
Special cases:STOP mode unavailable
In this case, the "ECO" warning lamp flashes for a few seconds, then goes off. This operation is per fectly normal.

* The weight of the braked trailer can be increased, within the GTW limit, if the GV W of the towin g vehicle is reduced by an equal amount. Warning: towing using a lightly loaded towing vehicle may have an adverse effect on its road holding.
The GTW and towed load values indicated are valid u p to a maximum altitude of 1 000 metres; the towed load mentioned must be reduced by 10 % for each additional 1 000 metres of altitude. The speed of a towing vehicle must not exceed 60 m ph (100 km/h) (comply with the legislation in force in your country). High ambient temperatures may result in a reduction in the per formance of the vehicle to protect the engine; if the ambient temperature is above 37 °C, limit the towed load.
