The following steps must be run in the order shown. If Steps 2,3, or 4 are interrupted, repeat the step before proceeding. Any safe driving mode is acceptable between steps.

Always drive vehicle in a safe manner according to traffic conditions and obey all traffic laws.
1. Start engine and drive vehicle in typical city stop-and-go traffic for at least 10 minutes after it has reached normal operating temperature.
2. Idle vehicle for at least 45 seconds, then accelerate at part throttle to near 72 km/h (45 mph).
3. Cruise and maintain a select speed in the range of 48-64 km/h (30 to 40 mph) on a level road with throttle held steady for at least one minute.
4. Drive to accumulate at least four minutes in the range of 32-72 km/h (20 to 45 mph). If stop-and-go conditions occur, the accumulated time must be within the 32-72 km/h (20 to 45 mph) range. No wide open throttle (WOT) conditions should be encountered.
5. Decelerate and idle for at least 10 seconds.
6. Accelerate to approach 88 km/h (55 mph) at 1/2 throttle (elapsed time is about 10 seconds).
7. Cruise and maintain select speed in the range of 64-104 km/h (40 to 65 mph) on a level road with throttle held steady for at least one minute and 20 seconds.
8. OBDII Drive Cycle has been completed.
