2012.5 Citroen DS3 brakes

149Safety
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
Anti-slip regulation (ASR)
and electronic stability
pro
gramme (ESP)
The anti-slip regulation (also known as TractionControl) optimises traction to prevent skiddingof the wheels, by acting on the brakes of the
driving wheels and on the engine.
The electronic stability programme 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.

)
Press the brake pedal when this
indicator lamp is displayed in the
instrument panel (e.g.: star tingthe engine).
Moving off
If position Nis engaged inadvertently while driving, allow the engine to return to idle then engage position Dto accelerate.
When the engine is running at idle, withthe brakes released, if position R, D
or Mis selected, the vehicle moveseven without the accelerator being pressed.
When the engine is running, never leave children in the vehicle withoutsupervision.
When carrying out maintenance with the engine running, apply the parkingbrake and select position P.P

Apply the parking brake. )
Select position Por N.)
Start the engine.
If this procedure is not followed, an audible
signal is heard, accompanied by a message in
the multifunction screen.) With the engine running, press the brake
pedal.

Select position R , D
or M . )
Gradually release the brake pedal.
The vehicle moves off immediately.

Checks

pads
Brake wear depends on the style
of driving, par ticularly in the case
of vehicles used in town, over shor t
distances. It ma
y be necessary to have the condition of the brakes checked, even between vehicle services. Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake pads are worn. The
gearbox does not require any
maintenance (no oil change).
Refer to the servicing booklet for the
details of the level checking interval for this component.















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 offers very specific products.
To avoid damaging the electrical units, the use of a high pressure washer in the engine compar tment is strictly prohibited.
The gearbox does not require any
maintenance (no oil change).
Refer to the ser vicing booklet for
details of the level checking inter val for this component.
Electronic gearbox
The gearbox does not require anymaintenance (no oil change).
Refer to the servicing booklet for
details of the checking interval for
this component.
For information on checkin
g brake
disc wear, contact a CITROËN dealer
or a qualified workshop.
Brake disc wear
Manual parking brake

If a loss of effectiveness of this system is noticed, the parking brake
must be checked, even between
tw
o services.
Checking this system must be done by aCITROËN dealer or a qualified workshop.

The rear parking sensors will be deactivated automatically if a genuineCITROËN towbar is used.
Cooling
Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its coolingcapacity is not dependent on the engine speed. )To lower the engine speed, reduce your
speed.
The maximum towed load on a long incline depends 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 avoid overheating of the brakes on a longmountain type of descent, the use of engine braking 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 signallingon the trailer.
)
If the warning lamp and the
STOPwarning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.

RACING towbar

Your vehicle cannot be fitted with a towbar. The space occupied by thesport diffuser prevents this.
