CHECK ENGINE Malfunction indicatorlight

On-Board Diagnostics II (OBDII): As you drive, a computer called "OBDII" monitors your vehicle's engine, transmission, electrical and emission systems. The CHECK ENGINE light will light up if the computer senses a condition that potentially may need correcting. When this happens, please have your vehicle checked by a trained and qualified Volvo service technician as soon as possible.
A CHECK ENGINE light may have many causes.
Sometimes, you may not notice a change in your vehicle's behavior. Even so, an uncorrected condition could hurt fuel economy, emission cleanliness, and driveability.
Extended driving without correcting the cause could even damage other components in your vehicle.
Canadian models are equipped
with this warning light.
