WARNING: This page is about a different car, the 2011 Nissan Armada. However, it is still accessible from the selected car via links, so may be relevant.
  1. Inspect the amount of engine oil and replenish if necessary.
  2. Drive the car for about 10 minutes to warm it up so that the ATF reaches in range of 50 to 80°C (122 to 176°F), then inspect the amount of ATF and replenish if necessary.
    NOTE: The automatic fluid temperature rises in range of 50 to 80°C (122 to 176°F) during 10 minutes of driving. 
  3. After warming up remove the oil pressure detection plug and install the Tool.
    CAUTION: When using the oil pressure gauge, be sure to use the O-ring attached to the oil pressure detection plug.
