2011.5 Citroen DS4 RHD brakes

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
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.

)With your foot on the brake, selectposition P
or N
. )Star t the engine.
If this procedure is not followed, there is an
audible signal, accompanied by a message in
the multifunction screen.)With the engine running, press the brakepedal. )Release the parking brake, unless it is programmed to automatic mode.)Select position R, D
or M,)Gradually release the brake pedal.
The vehicle moves off immediately.

If position N
is engaged inadver tentlywhile driving, allow the engine toreturn to idle then engage position D
toaccelerate.
When the engine is running at idle, withthe brakes released, if position R, Dor Mis selected, the vehicle moves even without the accelerator being pressed. When the engine is running, never leave children in the vehicle withoutsupervision. When carrying out maintenance withthe engine running, apply the parking brake and select position P.P


Automatic operation
)Select position D
for automatic
changing
of the six gears.
The gearbox then operates in auto-adaptive mode, without any inter vention on the par t
of the driver. It continuously selects themost suitable gear according to the style of
driving, the profile of the road and the load in
the vehicle.
For maximum acceleration without touching
the lever, press the accelerator pedal down fully (kick down). The gearbox changes down
automatically or maintains the gear selected
until the maximum engine speed is reached.
On braking, the gearbox changes down
automatically to provide efficient enginebraking.
If you release the accelerator sharply, the
gearbox will not change to a higher gear for safety reasons.

Never select position Nwhile thevehicle is moving. Never select positions Por R
unless the vehicle is completely stationary.

Electric parking brake
This system does not require anyroutine servicing. However, in the event of a problem, have the system checked by a CITROËN dealer or aqualified workshop.
For more information, see "Driving - Electric
parking brake - § Operating faults".

















Only use products recommended by CITROËN or products of equivalent quality and specification. In order to optimise the operationof units as impor tant as the braking system, CITROËN selects and offersvery specific products.
To a v o i d d a m aging the electrical units,the use of a high pressure washer in the engine compar tment is strictly
prohibited.Brake disc wear

For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.


Manual parking brake
If a loss of effectiveness of this
system is noticed, the parking brake must be checked, even betweentwo services.
Checking this system must be done by aCITROËN dealer or a qualified workshop.
Brake pads
Brake wear depends on the styleof driving, par ticularly in the case of vehicles used in town, over shor t
distances. It may be necessary to have the condition of the brakes checked,even between vehicle services. Unless there is a leak in the system, a drop in
the brake fluid level indicates that the brake pads are worn.

The rear parking sensors will be deactivated automatically if a genuine CITROËN towbar is used.

Driving advice
Distribution of loads
)Distribute the load in the trailer so that theheaviest items are as close as possible to
the axle and the nose weight approaches the maximum permitted without exceeding it.
Air density decreases with altitude, thus reducing engine per formance. Above
1 000 metres, the maximum towed load must
be reduced b
y 10 % for every 1 000 metres of altitude.
Refer to the "Technical Data" section for details
of the weights and towed loads which apply to your vehicle.
Side wind
)Take into account the increased sensitivity
to side wind.

Cooling

Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling capacity is not dependent on the engine speed.)
To lower the engine speed, reduce your speed.
The maximum towed load on a long inclinedepends on the gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.

Braking

To w i ng a trailer increases the braking distance.
To a v o i d o v e r h e a t i ng of the brakes on a long
mountain type of descent, the use of enginebraking is recommended.


Tyres
)Check the tyre pressures of the towing
vehicle and of the trailer, obser ving the recommended pressures.



Lighting
)Check the electrical lighting and signalling on the trailer.
)If the warning lamp and the
STOP warning lamp come on, stop the vehicle and switch off
t
he engine as soon as possible.
