1. Read the odometer to check the total distance the vehicle has been driven.

   Result

   Result		Proceed to
   Total distance driven is less than 200000 km (124280 mile)		A
   Total distance driven is 200000 km (124280 mile) or more	Current total distance driven - total distance driven when hybrid battery terminal block replaced = less than 200000 km (124280 mile) *1
   	Other than above	B

   HINT: 

   *1: If the hybrid battery terminal block has been replaced, use the total distance driven since it was replaced.
