HI,

Ok, to get the monitors to readiness, you need to perform a specific drive cycle, which is condition based, not mileage. Below is the drive cycle and you will need to perform it exactly as stated, in the order stated. You will need to do this 2 days in a row to set the monitors to readiness

  1. Ensure that the fuel tank is between 1/4 and 3/4 full.

  2. Start cold (below 86°F /30°C- let it sit overnight) and warm up until engine coolant temperature is at least 160° F (typically requires at least one minute; up to 3 minutes).

  3. Accelerate to 40-55 MPH at 25% throttle and maintain speed for five minutes.

  4. Decelerate without using the brake (coast down) to 20 MPH or less, then stop the vehicle. Allow the engine to idle for 10 seconds, turn the key off, and wait one minute.

  5. Restart and accelerate to 40-55 MPH at 25% throttle and maintain speed for two minutes.

  6. Decelerate without using the brake [or the clutch!] by coasting down to 20 MPH or less, then stop the vehicle. Allow the engine to idle for 10 seconds, turn the key off, and wait one minute.
