FLUID TEMP : 20°C (68°F) or more

With GST

  1.  Start the engine.
  2.  Set the CVT fluid to 20°C (68°F) or more.

NOTE: When the ambient temperature is 20°C (68°F), the CVT fluid usually increases to 50 to 80°C (122 to 176°F) with driving in an urban area for approximately 10 minutes. Is the CVT fluid 20°C (68°F) or more? YES >> GO TO 3.
