*4: Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher transmission
temperatures. This requires transmission fluid changes more frequently than recommended by the
Maintenance Minder
TM. If you regularly drive your vehicle under these conditions, have the transmission
fluid changed at every 30,000 miles (48,000 km) or 2 years.
*5: If you drive regularly in very high temperatures (over 110°F, 43°C), in very low temperatures (under
-20°F, -29°C), or towing a trailer, replace every 60,000 miles (U.S.) / 100,000 km (Canada).
*6: Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher level of mechanical (Shear) stress to fluid. This requires differential fluid changes more frequently than
recommended by the Maintenance Minder
TM. 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).
