>> GO TO 2.
2.PREPARATION BEFORE OPERATION 2
With CONSULT
FLUID TEMP : 20В°C (68В°F) or more
With GST
NOTE:
When the ambient temperature is 20В°C (68В°F), the CVT fluid usually increases to 50 to 80В°C (122 to 176В°F) with driving in an urban area for approximately 10 minutes.
Is the CVT fluid 20В°C (68В°F) or more? YES >> GO TO 3.
NO >> 1. Warm the transaxle.
2. GO TO 3.
