ESP

Electronic Stabilization Program (ESP)
The Electronic Stabilization Program (ESP) is a
driving dynamics regulation system. It stabilizes
the vehicle both in understeer and oversteer
situations. ESP regulation includes the functions
of EBD, ABS, EDL and ASR. A special function
of ESP is that it can brake individual wheels.

ESP includes the functions of EBD, ABS, EDL
and ASR. The individual components have
the following functions:
The ASR and ESP functions can be switched on
and off using the ASR/ESP switch on the center
console. If the driver steps on the brake pedal,
the status of the ESP switch is ignored. When
braking, ESP is always active. When the ignition
is switched on, the ASR and ESP functions are
activated.
When switched off, the ASR/ESP indicator light
is lit up in the instrument cluster. During
adjustment mode, the indicator lamp blinks three
times per second.
