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".

For DIS, the warning light for brake system -K118- "brake system 
malfunction" appears in the display. If the ABS warning light -K47 and the red symbol for "Brake system 
malfunction" are not lit, but the brake system is not functioning 
properly, check for malfunctions in the mechanical/hydraulic brake 
system components.
