2 Maintenance Procedures Engine Oil Level How to check engine oil level To check engine oil level, park vehicle on level ground and wait 15 minutes after shutting off engine. After the engine is shut off it will take at least 15 minutes for all the engine oil to return to the sump. NOTE It takes approximately 15 minutes for all the oil to run into the sump when the engine is ‘warm.’ If the level is checked immediately after switching off the engine, the dipstick will show a low oil level. 2. Wipe the dipstick clean with a lint- free cloth. 3. Reinsert the dipstick into the holder. 4. Remove the dipstick from the holder and check the oil level.
The oil level should always be between the two marks on the dipstick. Make sure that the vehicle suspension is sitting flat, both lengthwise and crosswise. Y53-1166-1G1 (08/2018) 49
