Maintenance Due Now does not appear more than 12 months after the display
is reset, change the engine oil every year.
# : See information on maintenance and emissions warranty in the first column on page 575.
*2: If you drive in dusty conditions, replace the air cleaner element every 15,000 miles (24,000 km).
*3: 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).
CODEMaintenance Main Items
A
●Replace engine oil*1
B●Replace engine oil*1 and oil filter●Inspect front and rear brakes●Check parking brake adjustment●Inspect tie rod ends, steering gearbox, and boots●Inspect suspension components●Inspect driveshaft boots●Inspect brake hoses and li nes (Including ABS/VSA®)●Inspect all fluid levels and condition of fluids●Inspect exhaust system#
●Inspect fuel lines and connections#
*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).
