See step  5

Pre-procedure1

• According to the display on the GTS, read the Data List and check that the value of each "Hybrid/EV Battery Temperature 1 to 3" is 40°C (104°F) or less.

  HINT: 

  If the value of any of "Hybrid/EV Battery Temperature 1 to 6" is more than 40°C (104°F), turn the ignition switch off and wait until the values to decrease to 40°C (104°F) or less before continuing this procedure.
