spinning during acceleration by reducing engine
load. It is active throughout the entire speed
range. The EDL and ASR functions work in
combination during vehicle acceleration.
ASR can be switched on and off by pressing the
traction control button in the center of the center
console. ASR is re-activated on its own when the
ignition is switched on. When the traction control
button is operated, the ASR indicator lamp lights
up in the instrument cluster. During adjustment
mode, the indicator lamp blinks three times per
second.

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

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.
