Park on a fairly steep hill, with the vehicle facing downhill. Keeping your foot on the regular brake, set the parking brake. • To check the parking brake's holding ability: With the engine running and transmission in NEUTRAL (N), slowly remove foot pressure from the regular brake pedal. Do this until the vehicle is held by the parking brake only. • To check the PARK (P) mechanism's holding ability: With the engine running, shift to PARK (P). Then release the parking brake followed by the regular brake. Contact your GM Goodwrench® dealer if service is required. Recommended Fluids and Lubricants Fluids and lubricants identified below by name, part number, or specification may be obtained from your dealer. Fluid/Lubricant The engine requires a special engine oil meeting GM Standard GM4718M. Oils meeting this standard may be identified as synthetic, and should also be identified with the American Petroleum Institute (API) Certified for Gasoline Engines starburst Engine Oil symbol. However, not all synthetic API oils with the starburst symbol will meet this GM standard. You should look for and use only an oil that meets GM Standard GM4718M. GM Goodwrench® oil meets all the requirements for your vehicle. For the proper viscosity, see Engine Oil on page 377. 50/50 mixture of clean, drinkable Engine Cooling water and use only DEX-COOL® Coolant. See Engine Coolant on System page 385. Usage Underbody Flushing Service At least every spring, use plain water to flush any corrosive materials from the underbody. Take care to clean thoroughly any areas where mud and other debris can collect. 473
