Driving Pattern
- Start the engine. Hold the engine speed at 3,000 rpm without load (in neutral) until the radiator fan comes on.
- Drive the vehicle at a speed between 45 - 75 mph (73 - 120 km/h) for at least 5 minutes, to warm up the TWC.
- Set a vehicle speed of 55 mph (88 km/h) on the cruise control, and drive for at least 1 minute.
- Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.
