2.PREPARATION BEFORE OPERATION (PART 2)
With CONSULT-III
1. Start the engine.
2. Select “Data Monitor” in “TRANSMISSION”.
3. Select “FLUID TEMP”.
4. Confirm that the CVT fluid temperature is in the following range.
FLUID TEMP : 10°C (50°F) or more
With GST
1. Start the engine.
2. Set the CVT fluid to 10°C (50°F) or more.
NOTE
