ENGINE OIL DI1299 DI1300 DI1301 CHECKING ENGINE OIL LEVEL 1. Park the vehicle on a level surface and apply the parking brake. 2. Start the engine and let it idle until it reaches operating temperature. 3. Turn off the engine. Wait a few minutes for the oil to drain back into the oil pan. 4. Remove the dipstick and wipe it clean. Reinsert it all the way. 5. Remove the dipstick again and check the oil level. It should be between the H (High) and L (Low) marks. If the oil level is below the L (Low) mark, remove the oil filler cap and pour recommended oil through the opening. Do not overfill. 6. Recheck the oil level with the dipstick. It is normal to add some oil between oil maintenance intervals or during the break-in period, depending on the severity of operating conditions. 8-8 Do-it-yourself
