There is a malfunction that causes damage to the catalytic converter in this driving condition (e.g. combustion misfire). In this case, vehicle must only be driven at reduced performance!

NOTE: Check DTC memory if there is a driveability problem or a customer complaint, but the Malfunction Indicator Lamp (MIL) -K83- is not lit. There may be DTCs stored that do not cause the exhaust MIL to light up immediately, but only after engine is started again and malfunction is recognized again.
