This requires transmission fluid changes more frequently than recommended by the Maintenance 
Minder. If you regularly drive your vehicle under these conditions, have the transmission fluid changed 
at 40,000 miles (64,000 km), then every 30,000 miles (48,000 km).

*7: Driving in mountainous areas at very low vehicle speeds results in higher level of mechanical (shear)  stress to fluid. This requires differential fluid changes more frequently than recommended by the 
Maintenance Minder. If you regularly drive your vehicle under these conditions, have the differential 
fluid changed at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km).
