2. Move the gearshift to the P(Park) position and turn off all electrical accessories.
3. Start the engine.
4. Let the engine idle until the temperature gauge shows normal operating temperature (middle of the gauge).
5. Allow the engine to idle for at least one minute after reaching operating temperature.
