One
of the most convenient and
important features of the multi-
info rmation display on your vehicle
is the maintenance minder.
Based on engine operating
conditions and accumulated engine
revolutions, the onboard computer in
your vehicle calculates the remaining
engine oil life.
The system also displays the code
for other scheduled maintenance
items needing service. The
remaining engine oil life is
displayed according to the table
shown below.

If
the message ‘‘SERVICE DUE NOW’’ does not appear more than 12
months after the disp lay is reset, change the engine oil every year.
See information on maintenance and emissions warranty in the first
column on page . Independent of the maintenance messages in the multi-information
display, replace the brake fluid every 3 years.
Inspect idle speed every 160,000 miles (256,000 km).
Adjust the valves during services A, B, 1, 2, or 3 if they are noisy. 461
If you drive in dusty conditions, replace every 15,000
miles (24,000 km).
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).
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).
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. 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).
