2 Replace dust and pollen filter
If you drive primarily in urban areas that have high
concentrations of soot in the air from industry and from diesel-
powered vehicles, replace every 15,000 miles (24,000 km).
Inspect drive belt
3 Replace transmission and transfer fluid
Driving in mountainous terrain at very low vehicle speeds,
towing a trailer, or driving when fully loaded results in higher
transmission and transfer temperatures. This requires
transmission and transfer fluid changes more frequently
than recommended by the Maintenance Minder.
If you regularly drive your vehicle under these conditions, have
the transmission and transfer fluid changed every 30,000 miles
(48,000 km).
4 Replace spark plugs
Replace timing belt and inspect water pump
If you drive regularly in very high temperatures (over 110°F,
244 .
43°C), in very low temperatures (under-20°F, -29°C), or towing a
trailer, replace every 60,000 mile (U.S.)/100,000 km (Canada)
Inspect valve clearance
5 Replace engine coolant
6 Replace VTM-4 rear differential fluid
Driving in mountainous terrain at very low vehicle speeds,
towing a trailer, or driving when fully loaded causes more
mechanical (shear) stress and fluid deterioration. 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).
