2012 Citroen DS4 wheel

Cornering lighting
With dipped or main beams, this function makes use of the beam from a front foglamp to
illuminate the inside of a bend, when the vehicle
speed is below 25 mph (approximately 40 km/h)(urban driving, winding road, intersections,
parking manouevres...).

Switching on
with cornering lighting
without cornering lighting


Switching off

The system does not operate:


- below a cer tain angle of rotation of thesteering wheel,

- above 25 mph (40 km/h),

- when reverse gear is engaged.
The s
ystem is activated by default.

Programming
The system is activated or deactivated in the vehicleconfiguration menu. Thi
s function starts:


- when the corresponding direction indicator is switched on,
or

- from a cer tain angle of rotation of the steering wheel.

To remove the shelf: )unhook the two cords, )raise the shelf slightly, then remove it.
There are several options for storing the shelf:
- either upright behind the front seats,
- or flat at the base of the boot.
Rear parcel shelf
The hooks can be used to secure shoppingbags.
Hooks


Access to the storage box

An additional hook under the shelf is used to hold up the boot floor using its cord, to facilitate access to the tools and spare wheel or the temporarypuncture repair kit...

Use
)Extract the torch from its location pulling it upwards.)Press the switch, located on the back,
to switch the torch on or off. )Unfold the suppor t, located on the back,
to set down and raise the torch; for
example, when changing a wheel.



Storing
)
Put the torch back in place in its locationstarting with the lower part.
If you have forgotten to switch off the torch,
this switches it off automatically.
Storage box
)Raise the boot carpet for access to
the storage box.
This has areas for the storage a box of spare
bulbs, a first aid kit, two warning triangles...
It also contains the vehicle tools, the temporarypuncture repair kit...
It the torch is not engaged correctly, it may not charge and may not come onwhen the boot is opened.

Safety
Automatic operation of
hazard warnin
g lamps
When braking in an emergency, depending on
the deceleration, the hazard warning lamps come on automatically.
They switch off automatically the first time you accelerate.)You can also switch them off by pressingthe button.






Horn
Audible warning system to alert other roadusers to an imminent danger. )
Press the central part of the mutlifunction steering wheel.
Use the horn moderately and only in the following circumstances: - immediate danger,- approaching a location lacking
visibility.









Emergency or
assistance call
This system allows you to make an emergency or assistance call to the emergency ser vices or
to the dedicated CITROËN ser vice.
F
or more information on the use of this
function, refer to the "Audio and telematics" section.

Ty r e u n d e r - i nfl ation detection
System which automatically and continuously checks the pressure of the tyres while driving.Sensors fitted in each valve trigger a warning
in the event of problem (speed above 12 mph(20 km/h)).

Puncture

The tyre under-inflation detectionsystem is an aid to driving which doesnot replace the need for the driver to bevigilant or to drive responsibly.


Under-infl ated tyre
This warning lamp is displayed on the
instrument panel and/or a message appears
in the screen, accompanied by an audible
si
gnal, to identify the wheel concerned.
The STOPwarning lamp comes on and/or this warning lamp is displayed on
the instrument panel, accompanied by
an audible signal and a message in the
screen identifying the wheel concerned.
)Stop as soon as it is safe to do so, avoiding any sudden movement of the steering
wheel and the brakes.)Repair or change the damaged wheel(punctured or very deflated tyre), and have
the tyre pressure checked as soon as possible.
) Check the tyre pressures as soon as possible.
This check must be carried out when the tyres
are cold.

177Safety

Sensor(s) not detected or faulty
A message appears in the screen,
accompanied by an audible signal, to identify
the wheel or wheels which are not detected or
to indicate a malfunction in the s
ystem.
Contact a CITROËN dealer or a qualified
workshop to replace the
faulty sensor(s).
All repairs and changing of tyres on a wheel fitted with this system must be carried out by a CITROËN dealer or aqualified workshop.
If, when changing a tyre, you install a wheel which is not detected by your vehicle (example: fitting of snow tyres),you must have the system reinitialised by a CITROËN dealer or a qualified workshop.
This system does not avoid the needto have the tyre pressures checkedregularly (refer to the "Identificationmarkings" section) to ensure that
the optimum dynamic performanceof the vehicle is maintained andprevent premature wear of the tyres, particularly in arduous driving conditions (heavy load, high speed). The tyre pressures must be checked cold, at least once a month. Remember to check the pressure of the spare wheel. The tyre under-inflation detection system may experience temporary inter ference due to electro-magnetic emissions on a frequency close to thatused by the system.

This message is also displayed when one of the wheels is away from the vehicle (being repaired) or when oneor more wheels without a sensor are fitted.
If your vehicle is equipped with a spare wheel, this is not fitted with a sensor.

Braking assistance systems
Group of supplementary systems which helpyou 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 surfaces.
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, pressvery firmly without releasing thepressure.


Operating fault
If this warning lamp comes on,
together with the STOPand ABSwarning lamps, accompanied by an
audible signal and a message in the 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 andrims), ensure that they conform to themanufacturer's recommendations.
If this warnin
g lamp comes on,
accompanied by an audible signaland a message in the screen, it
indicates a malfunction of the anti-lock brakingsystem which could result in loss of control of
the vehicle when braking.
In either case, contact a CITROËN dealer or a
qualified workshop.

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.
