YOUR 307 SW IN DETAIL
TRACTION CONTROL (ASR)
AND DYNAMIC STABILITY
CONTROL (ESP)
These systems are linked and com-
plement the ABS.
The ASR system optimises drive to
prevent the wheels skidding, by act-
ing on the brakes of the drive wheels
and on the engine. It also allows the
directional stability of the vehicle to
be improved on acceleration.
If there is a variation between the
trajectory followed by the vehicle and
that required by the driver, the ESP
system automatically acts on the
engine and the brake of one or more
wheels, in order to put the vehicle
back on course.
Disarming the ASR/ESP systems
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.
F
Press the
"ESP OFF"
switch, lo-
cated on the central section of the
fascia.
Operating check
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 functioning of these
systems depends on observation
of the manufacturer's recommenda-
tions regarding the wheels (tyres
and rims), the braking components,
the electronic components, and the
PEUGEOT assembly and operation
procedures.
After an impact, have the systems
checked by a PEUGEOT dealer.
Operation of the ASR and ESP
systems
The switch lights up and the
warning light comes on: the
ASR and ESP systems are
disarmed.
These are triggered again:
F
automatically if the ignition is
switched off,
F
automatically above 30 mph
(50 km/h),
F
manually by pressing the switch
again.
When a malfunction of the
systems occurs, the switch
light lashes and the warning
light comes on, accompanied
by an audible signal and the
message
"ESP/ASR not function-
ing"
on the multifunction display.
Contact a PEUGEOT dealer to have
the systems checked.
The warning light lashes if
the ASR or ESP is activated.
