TRAJECTORY CONTROL
SYSTEMS
Anti-slip regulation (ASR) and
electronic stability programme
(ESP)
The anti-slip regulation (also known as
Traction Control) optimises traction to
prevent skidding of 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 automati-
cally each time the vehicle is started.
They come into operation in the event
of a grip or trajectory problem.
This is indicated by fl ashing of
this warning lamp in the instru-
ment panel.
Deactivation
In exceptional conditions (starting a ve-
hicle which is bogged down, stuck in
snow, on soft ground...), it may be ad-
visable to deactivate the ASR and ESP
systems, so that the wheels can move
freely and regain grip.
S A F E T Y
Press the "ESP OFF" button, locat-
ed in the centre of the dashboard.
If this warning lamp comes on in
the instrument panel and the indi-
cator lamp on the button comes
on, this indicates that the ASR and
ESP systems are deactivated.
Reactivation
These systems are reactivated automa-
tically 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,
accompanied by an audible sig-
nal and a message in the multi-
function screen, this indicates a
malfunction of these systems.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.
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.
The correct operation of these
systems depends on observa-
tion of the manufacturer's rec-
ommendations regarding wheels
(tyres and rims), braking compo-
nents, electronic components
and assembly and repair proce-
dures.
After an impact, have these sys-
tems checked by a CITROËN
dealer or a qualifi ed workshop.
