Subaru Service Engine Soon IndicatorSubaru check engine lightCheck engine light


Service Engine Soon / Check Engine Light

The check engine light or service engine soon light when the onboard diagnostic system detects a problem with the engine, emission system, or transmission. 

A fault code is stored in the Engine Control Unit (ECU) and can be retrieved with an OBD-II scanner to determine what is wrong with the vehicle. 

Common problems that cause the check engine light on a Subaru vehicle:

  • Loose gas cap
  • Bad oxygen sensor
  • Dirty Mass Air Flow (MAF) sensor

Subaru  Air Bag Warning LightSubaru SRS AIRBAG LIGHT

Air Bag Warning Light

The airbag light turns on when you first turn on the ignition, but after a quick system check, it turns off if all the airbag components function properly.

If the airbag light stays, it means the airbags have been disabled and may not deploy in case of an accident. 

To troubleshoot the airbag light on a Subaru, you must read the fault codes with an airbag scanner. 

Subaru Engine Temperature Indicator Subaru Engine Temperature Indicator


Engine Temperature 

This is the warning symbol indicating that the engine has overheated. Pull over immediately and shut off the engine. Wait at least 30 minutes or more for the engine to cool down fully. 

Once the engine cools down, check the engine coolant level.

If the engine overheating continues, do not drive. Tow the vehicle to an auto repair shop near you. 

Common problems that cause a Subaru engine to overheat include:

  • Low coolant level 
  • Bad water pump
  • Broken coolant hoses
  • A faulty thermostat
  • Damaged heater core or radiator

Subaru  Low Fuel Indicator


Low Fuel Indicator

This light means that vehicle is low on fuel. Find a gas station and add fuel. Check the information display to estimate how many miles until the vehicle completely runs out of fuel. It is always a good idea to keep a vehicle from getting low on fuel as this causes the fuel pump to work harder and leads to excess and premature wear.

Common low fuel indicator causes on a Toyota vehicle:

  • Low fuel
  • Faulty fuel pump float
Subaru Oil Warning LightSubaru Oil and Oil Level Warning Lights


Oil Warning Light

This light means the oil pressure is outside of acceptable limits. Immediately check the pressure gauge on the dash to see the oil pressure level. Pull the vehicle over and turn the engine off when it is safe. Check the oil level to see if it is low. If the oil level is acceptable and the pressure is still low, this indicates a greater mechanical failure within the engine, such as a failed oil pump, worn piston rings, or blocked oil passages. Have the vehicle towed to a Subaru technician to have it diagnosed and serviced. Do NOT drive the vehicle with low oil pressure as it will cause almost immediate and serious damage to the engine.

Common causes of the low oil pressure indicator on a Toyota vehicle:

  • Bad oil pressure sending sensor
  • Failed oil pump
  • Worn piston rings
  • Blocked oil passages
  • Low oil or oil that has turned to sludge from never changing it
