TYRE UNDER-INFLATION

DETECTION

All repairs and changing of tyres

on a wheel ﬁtted with this system

must be carried out by a CITROËN

dealer.

If, when changing a tyre, you in-

stall a wheel which is not detected

by your vehicle (example: ﬁtting

of snow tyres), you must have the

system reinitialised by a CITROËN

dealer.

The STOP warning lamp

comes on in the instrument

panel, accompanied by an

audible signal and a mes-

sage on the multifunction

screen locating the wheel

concerned.

Sensors ﬁtted in each valve check

the tyre pressure during driving and

trigger a warning in the event of

malfunction (speed above 12 mph

(20 km/h).

Stop immediately, avoiding any sudden

movement of the steering wheel and

the brakes.

Change the damaged wheel (punctured

or very deﬂated tyre), and have the tyre

pressure checked as soon as possible.

Sensor(s) not detected or faulty

This system does not eliminate

the need to have the tyre pres-

sure checked regularly (refer to the

"Technical data - § Identiﬁcation

markings" section) to ensure that

the optimum dynamic perform-

ance of the vehicle is maintained

and prevent premature wear of the

tyres, particularly in arduous driv-

ing conditions (heavy load, high

speed).

The service warning

lamp comes on in the

instrument panel, ac-

companied by an audible

signal and a message on

the multifunction screen

locating the wheel or wheels which

are not detected or indicating a fault

in the system.

The tyre under-inﬂation detection

system is an aid to driving which

does not replace the vigilance or

responsibility of the driver.

Have the faulty sensor(s) checked

by a CITROËN dealer.

Flat tyre

The tyre pressures must be

checked cold, at least once a

month. Remember to check the

pressure of the spare wheel.

The service warning lamp

comes on in the instru-

mentpanel, accompanied

by an audible signal and

a message on the multi-

function screen locating

the wheel concerned.

This message is also displayed

when one of the wheels is away

from the vehicle (being repaired) or

when one or more wheels without a

sensor are ﬁtted.

The spare wheel is not ﬁtted wi

th a

sensor.

The tyre under-inﬂation detection

system may experience temporary

interference due to radio-electric

emissions on a frequency close to

tha

t used by the system.

Check the tyre pressures as soon as

possible. This check must be carried

out when the tyres are cold.

BRAKING ASSISTANCE

SYSTEMS

Emergency braking assistance

System which, in an emergency,

enables you to obtain the optimum

braking pressure more quickly, thus

reducing the stopping distance.

If this warning lamp comes

Group of supplementary systems

which help you to obtain optimum

braking in complete safety in emer-

gency situations:

on, accompanied by an au-

dible signal and a message

on the multifunction screen,

it indicates a malfunction of the anti-

lock braking system which could re-

sult in loss of control of the vehicle

when braking.

Activation

It is triggered by the speed at which

the brake pedal is pressed.

anti-lock braking system (ABS),

electronic brake force distribution

(EBFD),

The effect of this is a reduction in

the resistance of the pedal and an

increase in braking efﬁciency.

emergency braking assistance

(EBA).

If this warning lamp comes on,

together with the STOP and

ABS warning lamps, accom-

panied by an audible signal

and a message on the multifunction

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.

Anti-lock braking system

and electronic brake force

distribution

When braking in an emergency,

press ﬁrmly without releasing the

pressure.

Linked systems which improve the

stability and manoeuvrability of your

vehicle when braking, in particular

on poor or slippery surfaces.

VIII

In either case, contact a CITROËN

dealer.

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 replacing wheels (tyres and

rims), ensure that they conform to the

manufacturer's recommendations.

When braking in an emergency,

press very ﬁrmly without releasing

the pressure.

TRAJECTORY CONTROL

SYSTEMS

Intelligent Traction Control

system*

In exceptional conditions (starting a

vehicle which is bogged down, stuck

in snow, on soft ground...), it may be

advisable to deactivate the ASR and

ESP systems, so that the wheels

can move freely and regain grip.

Your vehicle has a system to help

driving on snow.

Anti-skid regulation (ASR)

and electronic stability

programme (ESP)

This automatic system continuously

checks for situations of difﬁcult sur-

face adhesion that could make it dif-

ﬁcult to move off or make progress

on deep fresh snow or compacted

snow.

In these situations, the system takes

over from the ASR system by opti-

mising the amount of wheel slip to

provide the best traction and trajec-

tory control, even without snow tyres

and with or without chains.

The anti-skid regulation (also known as

Traction Control) optimises traction to

prevent skidding of the wheels, by act-

ing 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.

Inextremelysevereconditions(snow

on top of ice, sand, deep mud…), it

can be useful to deactivate the ESP/

ASR systems to allow a degree of

wheel spin and so recover grip.

Activation

These systems are activated auto-

matically each time the vehicle is

started.

They come into operation in the event

of a grip or trajectory problem.

VIII

 Press the "ESP OFF" button, lo-

cated in the centre of the dash-

board.

This is indicated by ﬂashing

of this warning lamp on the

instrument panel.

If this warning lamp comes

on in the instrument panel

and the indicator lamp on the

button comes on, this indi-

cates that the ASR and ESP

systems are deactivated.

* Depending on engine type.

Reactivation

These systems are reactivated au-

tomatically each time the ignition is

switched back on or from 30 mph

(50 km/h).

The ESP/ASR systems offer ex-

ceptional safety in normal driving,

but this should not encourage the

driver to take extra risks or drive at

high speed.



Press the "ESP OFF" button again

to reactivate them manually.

The correct functioning of these

systems depends on observation

of the manufacturer's recommen-

dations regarding the wheels (tyres

and rims), the braking components,

the electronic components and the

CITROËN assembly and operation

procedures.

Operating fault

If this warning lamp comes

on, accompanied by an au-

dible signal and a message

on the multifunction screen,

this indicates a malfunction of these

systems.

After an impact, have these systems

checked by a CITROËN dealer.

Have the systems checked by a

CITROËN dealer.
