Malfunction Indicator Light (MIL) (Check Engine Light)

~1min read

This indicator is part of the engine control system that monitors various components of the emission control system. If this indicator illuminates while driving, it indicates that a potential malfunction has been detected somewhere in the emission control system.

This indicator also illuminates when the ignition switch is in the ON position and turns off a few seconds after the engine starts. If it illuminates while driving or does not come on when the ignition switch is turned to the ON position, take the vehicle to the nearest authorized HYUNDAI dealer and have the system inspected.

In general, your vehicle will still be drivable, but have the system inspected by an authorized HYUNDAI dealer.

CAUTION

  • Continued driving with the emission control system malfunction indicator illuminated may cause damage to the emission control systems, which may affect drivability and/or fuel economy.
  • If the emission control system malfunction indicator illuminates, there is potential damage to the catalytic converter, which may result in loss of engine power. Have the engine control system inspected by an authorized HYUNDAI dealer as soon as possible.
