CHECKING THE ENGINE OIL LEVEL
1. Make sure that your vehicle is on level ground. 2. Check the oil level before starting the
engine, or switch the engine off after
warming up and wait 10 minutes for the
oil to drain into the oil pan.
3. Remove the dipstick and wipe it with a clean, lint-free cloth.
4. Reinstall the dipstick and make sure it is
fully seated.
5. Remove the dipstick again to check the oil level.
Note: If the oil level is between the maximum
and minimum marks, the oil level is
acceptable. Do not add oil.
6. If the oil level is at the minimum mark, immediately add oil.
7. Reinstall the dipstick. Make sure it is fully
seated.
Note: The oil consumption of new engines
reaches its normal level after approximately
3,000 mi (5,000 km). ADDING ENGINE OIL WARNING:
Do not remove the filler
cap when the engine is running. WARNING:
Do not add engine oil
when the engine is hot. Failure to follow
this instruction could result in personal
injury.
Do not use supplemental engine oil additives
because they are unnecessary and could
lead to engine damage that the vehicle
warranty may not cover.
1. Clean the area surrounding the engine oil filler cap before you remove it.
2. Remove the engine oil filler cap.
3. Add engine oil that meets our specifications.
See Capacities and
Specifications (page 469).
4. Reinstall the engine oil filler cap. Turn it clockwise until you feel a strong
resistance.
