Unless you are technically qualified and have the proper tools, you should let your dealer perform this maintenance.
See Engine Compartment Overview for the supercharger oil fill location.
Check oil level every 30,000 miles (50 000 km) or every 36 months, whichever occurs first.
Use only the recommended supercharger oil. See Recommended Fluids and Lubricants .
Caution: If you remove the supercharger oil fill plug while the engine is hot, pressure may cause hot oil to blow out of the oil fill hole. You may be burned. Do not remove the plug until the engine cools.
Park the vehicle on a level surface. Check oil only when the engine is cold. Allow the engine to cool two to three hours after running.
