Safety








Ty r e u n d e r - i nfl ation detection
The system continuously monitors thepressures on the four tyres, once the vehicle is moving.
It compares the information given by the four
wheel speed sensors with reference values,
which must be reinitialised ever
y time the tyre pressures are adjusted or a wheel changed. The system triggers an aler t as soon as it
detects a drop in the inflation pressure of one
or more tyres.
The under-inflation detection system does not replace the vigilance or theresponsibility of the driver. This system does not avoid the need tocheck the tyre pressures (including the spare wheel) every month as well as before a long journey. Driving with under-inflated tyres impairsroad holding, extends braking distances and causes premature tyre wear,particularly under arduous condition(high loading, high speed, long journey). S
ystem which automatically checks the pressure of the tyres while driving.

The inflation pressures defined for your vehicle can be found on the tyrepressure label (see the "Identificationmarkings" section). Tyre pressures should be checkedwhen the tyres are "cold" (vehicle stopped for 1 hour or after a journey of less than 6 miles (10 km) at moderatespeeds). Other wise, add 0.3 bar to the pressures shown on the label.

Driving with under-inflated tyresincreases fuel consumption.

Under-inflation alert
Reinitialisation
This is given by fixed illumination of
this warning lamp, accompanied byan audible signal and, depending on
equipment, the display of a message.
A label reminds you of the need to reinitialise
the system every time one or more tyre
pressure is adjusted, and after changing one or
more wheels.
)Reduce speed immediately, avoidexcessive steering movements and sudden
braking .)Stop the vehicle as soon as it is safe
to do so.
) In the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (depending on equipment),or ) if you have a compressor, such as the one in the temporary puncture repair kit, check
the pressures of the four tyres when cold, or )
if it is not possible to make this check
immediately, drive carefully at reduced speed.



The loss of pressure detected does not always cause visible bulging of the tyre. Do not satisfy yourself with just a visual check. The aler t is maintained until the system is reinitialised.

Safety

Electronic Stability Programme (ESC: Electronic Stability Control) 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 (ESC)
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 according 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 by acting on the brakes of the driving
wheels 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
automaticall
y 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.

Safety
Intelligent traction control
s
ystem ("Snow motion")
When this warning lamp comes on,coupled with the STOPwarning lamp,
accompanied by an audible signal and a
message, it indicates that there is a fault
with the electronic brake force distribution(EBFD), which could cause loss of control of the vehicle when braking.

Operation
When this warning lamp comes on,
accompanied by an audible signaland a message, it indicates that there
is a fault with the ABS, which could cause loss of control of the vehicle
when braking.
Your vehicle has a system to help driving onsnow: 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 snow
or compacted snow.
In these situations
, the intelligent traction control limits the amount of wheel slip to provide the best traction and trajectory controlfor your vehicle.
In extremely severe conditions (deep snow,mud, ...), when it proves impossible to move off,
it may be useful to temporarily deactivate theESP/ASR systems to allow the wheels to spin
freely and so allow movement of the vehicle.
The use o
f snow tyres is strongly recommended on sur faces offering low levels of adhesion.

Anti-lock braking system (ABS)
and electronic brake force
distribution
(EBFD)

When changing wheels (tyres and rims),make sure that these are approved for your vehicle.
Normal operation of the ABS may make itself felt by slight vibrations of the brake pedal.
In emergency braking, press very firmly without releasing the pressure.
You must stop as soon as it is safe to do so.
In both cases, contact a CITROËN dealer or a qualified workshop.
