brakes Citroen DS5 HYBRID4 2012 1.G Owner's Manual

Engagement of reverse gear is accompanied by an audible signal.
If you leave the vehicle, place the gear selector in position Nand then you muststop the hybrid system by switching off the ignition (Ready
lamp off).
If the gear selector is not in position Non starting, Nflashes in the instrumentpanel, accompanied by an audible signal and a message in the instrument panel screen.Foot on brake
flashes on theinstrument panel, accompanied by anaudible signal and a message in theinstrument panel screen, if the brakepedal is not pressed on star ting.

When the engine is idling with the
brakes off, if position R, Aor M
is selected, the vehicle will move off on its own without any action on theaccelerator.

The gearbox is then operating in auto-active mode, without any action on the par t of thedriver. It continuously selects the most suitable gear, depending on the:


- style of driving,

- profile of the road.


For optimum acceleration, for example when overtaking another vehicle, press the accelerator pedal firmly past the point of resistance.

Ty r e u n d e r - i nfl ation detection System which automatically checks the pressure of the tyres while driving.
Sensors fitted in each valve trigger a warning in
the event of malfunction (speed above 12 mph(20 km/h)).
The spare wheel is not fitted with a sensor.

All repairs and changing of tyres on a wheel fitted with this system must becarried out by a CITROËN dealer or a
qualified 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 qualifiedworkshop.
This message is also displayed whenone of the wheels is away from thevehicle (being repaired) or when one or more wheels without a sensor are fitted.


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

This system does not avoid the needto have the tyre pressures checkedregularly (refer to "Identification markings") to ensure that the optimumdynamic per formance of the vehicle is maintained and prevent premature wear of the tyres, particularly inarduous 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 detectionsystem may experience temporary inter ference due to electromagnetic signals on a frequency close to thatused by the system.
A message appears in the instrument panel screen, accompanied by an audible signal,
to identify the wheel concerned.
Under-infl ated tyre
This warning lamp andthe STOPwarning lamp come on, accompanied by
an audible signal and a message in the instrument
panel screen identifying the wheel concerned. ) Stop immediately, avoiding any sudden
movement of the steering wheel and thebrakes.) Change the damaged wheel (punctured or
very deflated tyre), and have the tyre pressure checked as soon as possible.


Puncture

A message appears in the instrument panel
screen, accompanied by an audible signal,
to identi
fy the wheel or wheels which are not
detected or to indicate a fault in the system.
Contact a CITROËN dealer or a qualified
workshop to replace the faulty sensor(s).


Sensor(s) not detectedor faulty
)Check the tyre pressures as soon as possible. This check must be carried out when the tyres are cold.

183Safety
Electronic Stability Programme incorporating
the following systems:


- the anti-lock braking system (ABS) and the electronic brake force distribution (EBFD),

- the emergency braking assistance,

- the anti-slip regulation (ASR) or tractioncontrol,

- the dynamic stability control (DSC).






























Electronic stability programme (ESP)
Definitions
Anti-lock braking system (ABS)and electronic brake force
distribution (EBFD)
This system improves the stability and
manoeuvrability of your vehicle when braking and provides improved control in corners, in par ticular on poor or slippery road surfaces.
The ABS prevents wheel lock in the event of
emergency braking.
The electronic brake force distribution system
manages the braking pressure wheel by wheel.
Emergency braking assistance
In an emergency, this system enables you to reach the optimum braking pressure more quickly and therefore reduce the stopping distance. It is triggered in relation to the speed at which
the brake pedal is pressed. This is felt by a reduction in the resistance of the pedal and an increase in the effectiveness of the braking.

Anti-slip regulation (ASR)

The ASR system (also known as Traction Control) optimises traction in order to avoid
wheel slip b
y acting on the brakes of the drivingwheels and on the engine. It also improves
the directional stability of the vehicle onacceleration.


Dynamic stability control(DSC)

If there is a difference between the path followed by the vehicle and that required bythe driver, the DSC monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws of physics.

227Practical information

We recommend the use of genuine
CITROËN towbars and their harnesses that have been tested and approvedfrom the design stage of your vehicle,and that the fitting of the towbar is
entrusted to a CITROËN dealer or aqualified workshop.
If the towbar is not fitted by a CITROËN dealer, it is imperative that it isfitted in accordance with the vehiclemanufacturer's instructions.
Driving advice
Distribution of loads
)
Distribute the load in the trailer so that the
heaviest items are as close as possible to
t
he axle and the nose weight approaches the
maximum permitted without exceeding it.
Air density decreases with altitude, thus
reducing engine performance. Above
1 000 metres, the maximum towed load must
be reduced b
y 10 % for every 1 000 metres of altitude.
Side wind
)
Take into account the increased sensitivity
to side wind.

Cooling
To w i ng 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.
)If the warning lamp and the STOP
warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.

Braking

To w i ng a trailer increases the braking distance.
To avoid overheating of the brakes on a long
mountain type of descent, the use of enginebraking is recommended.

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



Lighting
)
Check the electrical lighting and signalling on the trailer.



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



Driving with a trailer places greater demands on the towing vehicle and the driver must take par ticular care.
The maximum towed load on a long incline depends on the gradient and the ambient
tem
perature.
In all cases, keep a check on the coolant
temperature.
R
efer to the "Technical Data" section for details
of the weights and towed loads which apply toyour vehicle.

243Checks
6-speed electronic gearbox
The gearbox does not require anymaintenance (no oil change).
Refer to the ser vicing booklet for
details of the checking interval for
this component.
Brake wear depends on the st
yle
of driving, par ticularly in the case
of vehicles used in town, over shor tdistances. It may be necessary tohave the condition of the brakes checked, evenbetween vehicle services.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brakepads are worn.















Brake pads

For information on checking brake
disc wear, contact a CITROËN dealer or a qualified workshop.
Brake disc wear
Electric parking brake
This system does not require anyroutine servicing. However, in the
event of a problem, have the systemchecked by a CITROËN dealer or aqualified workshop.

















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.
For more information, refer to the "Electric parking brake - Operating faults" section.
