Trajectory Control Systems - CITROËN C3 PICASSO 2012 Owner's Handbook Manual

Safety

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 automatically
each time the vehicle is started.
They come into operation in the event of a grip
or trajectory problem.
This is indicated by flashing
of this warning lamp in the
instrument panel.

Deactivation
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.
Press the "ESP OFF" button, located in
the centre of the dashboard.
If this warning lamp comes on
in the instrument 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 automatically
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 signal
and a message in the multifunction
screen, this indicates a malfunction
of these systems.
Have it checked by a CITROËN dealer or a
qualified workshop.
The ESP/ASR systems offer exceptional
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 observation of
the manufacturer's recommendations
regarding wheels (tyres and rims),
braking components, electronic
components and assembly and repair
procedures.
After an impact, have these systems
checked by a CITROËN dealer or a
qualified workshop.
