SAFETY
106
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 functioning of these
systems depends on observation
of the manufacturer's recommen-
dations on:
-
wheels (tyres and rims),
- braking system components,
- electronic components,
- assembly and repair proce-
dures.
After an impact, have these systems
checked by a PEUGEOT dealer or a
quali fi ed workshop.
Deactivation
In exceptional conditions (starting 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, located
in the centre of the dashboard.
If this warning lamp comes on in the instru-
ment panel and the indicator lamp in 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,
accompanied by an audible sig-
nal and a message in the multi-
function screen, this indicates a
malfunction of these systems.
Have them checked by a PEUGEOT
dealer or a quali fi ed workshop.
TRAJECTORY CONTROL
SYSTEMS
Activation
These systems are activated automati-
cally each time the vehicle is started.
Anti-slip regulation (ASR) and
electronic stability programme
(ESP)
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.
Steering/ESP coupling system
(SSP)
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.
This system optimises the stability of
the vehicle and its braking capacity by
combining the actions of the ESP and
electric power steering when braking on
surfaces on which the grip of the right-
hand and left-hand wheel differs.
It permits increased braking of the
wheels which are in contact with the
section of road offering the higher level
of grip and, anticipating the instability of
the vehicle, the application of a slight
correction to the turning angle of the
wheels to assist the driver in maintain-
ing his trajectory.
