Safety precautions and troubleshooting
basics


ABS/EDL/ASR and ESP are vehicle safety
systems; working on these systems requires
specific system knowledge.
There are two different versions of instrument
cluster: with or without Driver Information
System (DIS).

Instrument cluster without DIS
If On Board Diagnostic (OBD) has detected a malfunction in the
system, it indicates the malfunction by lighting up warning lamps when
ignition is switched on. The warning lamps are located in the
instrument cluster. This appears in both versions, with or without DIS.
The instrument cluster without DIS displays the ABS warning light -
K47- (right arrow), the warning light for brake system -K118- (center
arrow, red symbol for "brake system malfunction") and the traction
control indicator light -K86- (left arrow). For additional information, see
the section titled "Overview of indicator lamp functions".
