When you acknowledge the CHANGE OIL SOON message by clearing it from the display, you still must reset the engine oil life system separately. See Engine Oil Life System , Engine Oil , and Scheduled Maintenance for more information.

If the LOW OIL LEVEL message appears, and your vehicle has been parked on level ground with the engine off for at least 30 minutes, the oil level should be checked by observing the oil dipstick. Prior to checking the oil level, be sure the engine has been off for a few minutes and your vehicle is on a level surface. Then check the dipstick and add oil if necessary. See Engine Oil .
