• Ensure engine is at normal operating temperature, above 170°F.
• Operate the vehicle for a period of time, more than 2 minutes, at a speed above 25 MPH.
• Bring the vehicle to a complete stop, with foot on the brake and transaxle in gear (A/T) or neutral (M/T).

The monitor should run while vehicle is stopped with the engine idling. Wait for a few minutes to allow the monitor to complete before turning off engine.
