2012 Citroen DS4 stop start

A few definitions…
This value may vary following a changein the style of driving or the relief,resulting in a significant change in thecurrent fuel consumption.

If dashes are displayed continuously while driving in place of the digits, contact a CITROËN dealer or a qualified workshop.
This function is only displayed from 20 mph (30 km/h).
The fuel consumption of your vehicle will be higher than the official figures obtainedby CITROËN during the first 3 000 miles(5 000 km) of the vehicle's life.
Range
(miles or km)This indicates the distancewhich can still be travelled with the fuelremaining in the tank in relation to the average
fuel consumption over the last few miles(kilometres) travelled.
When the ran
ge falls below 20 miles (30 km),
dashes are displayed. After filling with at least 5 litres of fuel, the range is recalculated and is
displayed when it exceeds 60 miles (10 0 km).

Current fuelconsumption
(mpg or l/100 km or km/l)
This is the average fuel consumption during the last few seconds.


Average fuel consumption
(mpg or l/100 km or km/l)
This is the average fuel consumption since the last trip computer zero reset.
Average speed
(mph or km/h)This is the average speed calculatedsince the last trip computer zero reset (ignition on).
Distance travelled
(miles or km)This indicates the distancetravelled since the last trip computer zero reset.
Stop & Start time counter
(minutes/seconds or hours/minutes)
If your vehicle is fitted with Stop & Star t, a timecounter calculates the time spent in STOP mode during a journey.
It resets to zero every time the ignition isswitched on with the key.

Recommendations for ventilation and air conditioning


If after an extended stop in sunshine, the interior temperature is veryhigh, first ventilate the passenger compartment for a few moments. Put the air flow control at a setting high enough to quickly change the air in the passenger compartment.
The air conditioning system does notcontain chlorine and does not present any danger to the ozone layer.

In order for these systems to be fully effective, follow the operation and maintenance guidelines below: )
To obtain an even air distribution, take care not to obstruct the exterior air intake grilles located at the base of the windscreen, the nozzles, the vents and the air outlets, as wellas the air extractor located in the boot. )
Do not cover the sunshine sensor, located on the dashboard; this is used for regulation of the digital air conditioning system. )
Operate the air conditioning system for at least 5 to 10 minutes, once or twice a monthto keep it in per fect working order. )
Ensure that the passenger compar tment filter is in good condition and have the filter elements replaced regularly (refer to the "Checks" section). We recommend the use of a combined passenger compartment filter. Thanks to its special active additive, it contributes to the purification of the air breathed by theoccupants and the cleanliness of the passenger compartment (reduction of allergic symptoms, bad odours and greasy deposits).)
To ensure correct operation of the air conditioning system, you are also advised to haveit checked regularly as recommended in the ser vicing booklet.
)
If the system does not produce cold air, switch it off and contact a CITROËN dealer or a qualified workshop.
When towing the maximum load on a steep gradient in high temperatures, switching off theair conditioning increases the available engine power and so improves the towing ability.


The condensation created by the air conditioning results in a dischargeof water under the vehicle which is perfectly normal.




Stop & Start
The heating and air conditioning systems only work when the engine is running. To maintaina comfor table temperature in the passenger compartment, you can temporarily deactivatethe Stop & Start system (see "Driving").

conditioning


With Stop & Star t, when the demisting, air conditioning and air flow functionsare activated, STOP mode is not available.

Automatic visibility programme
)
Select this programme to demist or defrost
the windscreen and side windows as quickly as possible.
The system automatically manages the air conditioning, air flow and air intake, and
provides optimum distribution towards the
win
dscreen and side windows.) To stop the programme, press either the "visibility"button again or "AU TO " , the
warning lamp on the button goes off and
the warning lamp on the "AUTO"
button comes on.
The system starts again with the values in
use before it was overridden by the visibilityprogramme.

Starting the vehicle
)Inser t the key in the ignition switch.
The system recognises the star ting code. )Turn the key fully towards the dashboard toposition 3 (Starting).)When the engine starts, release the key.
) Immobilise the vehicle.)
Turn the key fully towards you to
position 1 (Stop).) Remove the key from the ignition switch.



Switching the vehicle off


A heavy object (key fob...), attached tothe key and weighing down on its shaft in the ignition switch, could cause amalfunction.
Key left in the "Ignition on"position
On opening the driver's door, an aler t message is displayed, accompanied by an audible signal, to remind you that the key is still in the ignition switch atposition 1 (Stop)
.
If the key has been left in the ignitionswitch at position 2 (Ignition on),the ignition will be switched off automatically after one hour. To switch the ignition back on, turn the key to position 1 (Stop)
, then back toposition 2 (Ignition on).

179Safety
Emergency braking assistance
System which, in an emergency, enables you
to obtain the optimum braking pressure more
quickly, thus reducing the stopping distance.

Activation

It is triggered by the speed at which the brake pedal is pressed.
The effect of this is a reduction in theresistance of the pedal and an increase in
braking efficiency.
When braking in an emergency, press firmly without releasing the pressure.

















Trajectory control systems (ESP)
Anti-slip regulation (ASR)
and electronic stability
control (ESC)
The anti-slip regulation (also known as traction control) optimises traction to prevent skidding
of the wheels, by acting on the brakes of the
driving wheels and on the engine.The electronic stability control acts on the brake
of one or more wheels and on the engine to keep the vehicle on the trajectory required by the
driver, within the limits of the laws of physics.

Activation
These systems are activated automaticallyeach time the vehicle is started.
They come into operation in the event of a gripor trajectory problem.
This is indicated b
y flashing of this
warning lamp in the instrument panel.

Intelligent traction control
s
ystem ("Snow motion")
Your vehicle has a system to help driving on snow: intelligent traction control.
This system detects situations of difficult surface adhesion that could make it difficult to
move off or make progress on deep fresh snowor compacted snow.
In these situations, the intelligent tractioncontrol limits the amount of wheel slip to
provide the best traction and trajectory control
for your vehicle.
The use of snow tyres is strongly recommended on surfaces offering low levels of adhesion.

Driving
)Pierce the protective cover Don the tube Ewith the release device. )Place the release device in the tube.)Turn the release device clockwise.For
safety reasons, it is essentialto continue
turning the device until it reaches its stop.
The parking brake is released. )Remove the release device and store it
with the blocks in the toolbox under theboot carpet.


For safety reasons, after this operationit is essential to contact a CITROËN dealer or a qualified workshop without delay to replace the protective cover.
Following an emergency unlocking,immobilisation of the vehicle is nolonger assured once the manual emergency release has been deployed
and the manual control does not allowthe re-application of your parkingbrake.
Take no action, either on the control lever A, or stopping starting the engine while the release device is engaged.
Take care not to allow moisture or dust in the proximity of the protective cover. - The operation o
f the parking brake reinitialises when the ignition is switched
off then on again. If the reinitialisation
of the parking brake proves impossible, contact a CITROËN dealer or a qualified
workshop.
- The subsequent time required for
app
lication may be longer than during
normal operation.

Stop & Start The Stop & Start system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...). The engine restar ts automatically - START mode - as soon as you want to move off. The restar t takes place instantly, quickly and silently.
Per
fect for urban use, the Stop & Star t system reduces fuel consumption and exhaust emissions as well as the noise level when stationary.
Operation
Going into engine STOP mode
With the electronic 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 asbraking, power steering, for example.
Never refuel with the engine in STOPmode; you must switch off the ignition with the key. Th
e "ECO"warning lamp comes on
in the instrument panel and the engine goes into standby automatically:
-with a manual gearbox , at speeds below
12 mph (20 km/h), when you put the gear lever into neutral and release the clutchpedal,
- with the 6-speed electronic gearbox
system, at a speed below 5 mph (8 km/h),
when you press the brake pedal or put thegear lever into position N.
If your vehicle is fitted with the system, a time counter calculates
the sum o
f 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 star t using the key,

- the electric parking brake is applied or
bein
g applied,

- the engine is needed to maintain acomfortable temperature in the passenger compartment,

- demisting is active,

- some special conditions (battery charge, engine temperature, braking assistance,ambient temperature...) where the engine isneeded to assure control of a system.


Special cases: STOP modeunavailable

In this case, the "ECO"warning lamp
flashes for a few seconds, then goes off.
This operation is per fectly normal.
