TRAJECTORY CONTROL SYSTEMS
Anti-skid regulation (ASR) and
electronic stability programme
(ESP)
The anti-skid regulation 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.
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. T h i s i s i n d i c a t e d b y fl a s h i n g

I n e x c e p t i o n a l c o n d i t i o n s ( s t a r t i n g a
vehicle which is bogged down, stuck
in snow, on soft ground, ...), it may
be advisable to disarm the ASR and
ESP systems, so that the wheels
can move freely and regain grip.
Press the "ESP OFF" button, lo-
cated in the centre of the fascia. Reactivation
These systems are reactivated au-
tomatically 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.
If this warning light comes
on on the instrument panel
and the indicator light on the
button comes on, this indi-
cates that the ASR and ESP
systems are disarmed. Operating fault
If this warning light comes
on, accompanied by an au-
dible signal and a message
on the multifunction display,
this indicates a malfunction of these
systems.
Have the systems checked by a
CITROËN dealer.
