The ESP/ASR systems offer excep-
tional safety in normal driving, but
this should not encourage the driver
to take extra risks or drive at high
speed.
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.
After an impact, have these systems
checked by a CITROËN dealer.
Deactivation
In exceptional conditions (starting a vehi-
cle 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.
 Press the "ESP OFF" button, locat-
ed in the centre of the dashboard. If this warning lamp comes on in the instru-
ment panel and the indicator lamp on the
button comes on, this indicates that the
ASR and ESP systems are deactivated.
Reactivation
These systems are reactivated automat-
ically each time the ignition is switched
back on or from 30 mph (50 km/h).

 Press the "ESP OFF" button again
to reactivate them manually. Operating fault
If this warning lamp comes on, ac-
companied by an audible signal and a
message on the multifunction screen,
this indicates a malfunction of these
systems.
Have the systems checked by a CITROËN dealer.
TRAJECTORY CONTROL SYSTEMS
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, within
the limits of the laws of physics.
Anti-skid regulation (ASR) and electronic stability programme (ESP)
This is indicated by fl ashing of
this warning lamp on the instru-
ment panel.
Activation
These systems are activated automati-
cally each time the vehicle is started.
They come into operation in the event
of a grip or trajectory problem.

CHECKS
Only use products recommended
by CITROËN or products of equiv-
alent quality and specifi cation.
In order to optimise the operation
of units as important as the braking
system, CITROËN selects and of-
fers very specifi c products.
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compartment
is strictly prohibited .
Brake disc wear
Brake pads Manual parking br ake
Brake wear depends on the
style of driving, particularly in
the case of vehicles used in
town, over short 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 fl uid level indicates
that the brake pads are worn. For information on checking
brake disc wear, contact a
CITROËN dealer.
If a loss of effectiveness of this
system is noticed, the parking
brake must be checked, even
between two services.
Checking this system must be
done by a CITROËN dealer.
Manual gearbox
The gearbox does not re-
quire any maintenance (no oil
change).
Refer to the Maintenance and
Warranty Guide for the details
of the level checking interval
for this component.
