The short version

Motor Coach Industries, Inc reported a problem with the exterior lighting hazard flashing warning lights. Here is what owners need to know.

WHAT

Please see the complete list of models above. The instrument panel indicator light may not illuminate when the hazard warning lights are on and the master run switch is in the 'Off' position.

WHY IT MATTERS

Without the illuminated reminder, the driver may fail to turn off the exterior lights when no longer needed. Hazard warning lights that remain activated unintentionally can confuse other drivers, increasing the risk of a crash.

WHAT TO DO

MCI will update the software, free of charge.
