Electronic stabilization program (ESP)
This warning/indicator light monitors the electronic stabi ­
lization program.
The warning/indicator light has the following functions:
• I t blinks while you are driving when the ESP is working.
• It illuminates when you switch on the ignition for approximately
2 seconds as a function check.
• It il luminates when there is a malfunction in the ESP.
• It illuminates when ESP or ASR (Anti-S lip Regulation) is deacti­
vated .
• It illuminates if there is a malfunction in the ABS, since the ESP
is part of the ABS system.
If the battery terminals were disconnected and re-connected, the
vehicle was jump started or the battery is
very weak, the ESP sensor
system goes through a learning process for the first few yards. The
warning/indicator light i lluminates . The warning/indicator light
goes out as soon as the learning process is complete.
If the ESP warning/indicator light illuminates and stays on after you
have started the engine, this may mean that the control system has
te mporarily switched off the ESP. If this is case, you can reactivate
the ESP by turning the ignition off and then on again . The
warning/indicator light should go out to show that the system is
fully functional again.
