tronic and mechanical tools that can help
prevent future costly repairs.
The maintenance intervals shown should be
performed as indicated in this section.

• Under no circumstances should oil change
intervals exceed12,500 miles (20,000 km)
or 12 months, whichever comes first.
•Flush and replace the engine coolant at
120 months or 150,000 miles (240,000 km)

At Each Stop for Fuel
• Check the engine oil level about 5 minutes
after a fully warmed engine is shut off.
Checking the oil level while the vehicle is
on level ground will improve the accuracy of
the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.• Check the windshield washer solvent and
add if required.
Once a Month
• Check tire pressure and look for unusual
wear or damage. Rotate tires at the first
sign of irregular wear, even if it occurs
before the oil indicator system turns on.
• Inspect the battery and clean and tighten
the terminals as required.
• Check the fluid levels of the coolant reser-
voir, and brake master cylinder; add as
needed.
• Check all lights and other electrical items
for correct operation.At Each Oil Change
• Change the engine oil filter.
• Inspect the brake hoses and lines.
• Inspect for the presence of water in the fuel
filter/water separator unit.
