Electronic Stabilization Program (ESP}
r /
The warning/indicator light monitors the electronic

The warning/ind icator light ,., has the following functions:
• it flashes wh ile you are drivi ng, when the ESP or the ASR (Ant i-Slip
Regulation) is working .

seconds as a funct ion check .
• it illum inates w hen there is a malfunction in the ESP .
• it illum inates after the battery has been disconnected.
• it illum inates continuously when the ESP is switched off.
• it illumi nates if the re is a malfunct ion in t he ABS, s ince the ESP is
part of the ABS system.
If the ESP warning/ind icator light ill umina tes and stays on after you
have started the engine, this may mean that the co ntro l system has
tempo rari ly switched off the ESP. If this is case , you can reactivate
the ES P by sw itch ing t he ig nit ion off and the n on agai n. The
warning/indicator light should go out to show that the system is fu lly
fu nctional again .
The ESP warn ing/ind icator light will illuminate when the ignition is
switched on if th e ve hicle bat tery has been disconnected and the n
reconnected aga in . The light should go ou t after dr iv ing a short
dis tance if the steer ing whee l is turned s lig htly.
