Electronic Stability Control (ESC)*  / 
There are two control lamps for the electronic stability control. The lamp 
provides information concerning the function and the  disconnection sta-
tus.
Both warning lamps light up together when the ignition is switched on and
should turn off after approximately 2 seconds. This is the time taken for the
function check.
1)
Depending on the version of the model.
This programme includes the ABS, EDL and ASR. This also includes the
brake assistance system (BAS), automatic cleaning of the brake discs and

the trailer stability programme (TSP).
The warning lamp  has the following functions:
● It flashes whilst driving when the ASR/ESC is activated.
● It will light up if there is a fault in the ESC.
● As the ESC operates in conjunction with the ABS, it will also light up if a
fault should occur in the ABS.
If the ESC control lamp  lights up and stays on after the engine is started,
this may mean that the control system has temporarily switched off the ESC.
1)
: EXHAUST GAS SEE
In this case the ESC can be reactivated by switching the ignition off and
then on again. If the control lamp goes out, this means the system is fully
functional.
The  lamp provides information about the disconnection status of the
system:
● It stays lit when the ASR is disconnected when pressing the  switch.
