plement the ABS.
The ASR system optimises drive to prevent the wheels skidding, by act-ing on the brakes of the drive wheelsand on the engine. It also allows thedirectional stability of the vehicle tobe improved on acceleration. If there is a variation between the tra- jectory followed by the vehicle and
that required by the driver, the ESPsystem automatically acts on theengine and the brake of one or morewheels, in order to put the vehicleback on course.Operating check

and the message "ESP/ASR not

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 canmove freely and regain grip.
Press the "ESP OFF" switch,
located on the central section of the fascia.
The switch lights up and thewarning light comes on: the
ASR and ESP systems aredisarmed.
These are triggered again: automatically if the ignition is
switched off,
automatically above 30 mph (50 km/h),
manually by pressing the switchagain.
Operation of the ASR and ESP systems
The warning light flashes if
the ASR or ESP is activated.
The ESP/ASR systems offer exceptional safety innormal driving, but thisshould not encourage thedriver to take extra risks
or drive at high speed. The correct functioning of these systems depends on observationof the manufacturer's recommen-dations regarding the wheels (tyresand rims), the braking components,the electronic components, and thePEUGEOT assembly and opera-tion procedures. After an impact, have the system
checked by a PEUGEOT dealer.
