CAUTION:
Be careful of the driving speed.
1.PREPARATION BEFORE OPERATION 1
If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at
least 10 seconds, then perform the next test.
>> GO TO 2.
2.PREPARATION BEFORE OPERATION 2
With CONSULT
1. Start the engine.
2. Select “Data Monitor” in “TRANSMISSION”.
3. Select “FLUID TEMP”.

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.
