(h) Change automatic transaxle fluid and filter if
the vehicle is mainly driven under one or more of
these conditions:
− In heavy city traffic where the outside
temperature regularly reaches 90°F (32°C)
or higher.
− In hilly or mountainous terrain.
− When doing frequent trailer towing.
− Uses such as found in taxi, police, or
delivery service.
(i) Drain, flush, and refill cooling system. This
service can be complex; you should have
your dealer perform this service. See Engine
Coolant on page 363 for what to use. Inspect
hoses. Clean radiator, condenser, pressure cap,
and filler neck. Pressure test the cooling
system and pressure cap.

binding and for damaged or missing parts. Replace
parts as needed. Replace any components that
have high effort or excessive wear. Do not
lubricate accelerator or cruise control cables.
(k) A fluid loss in any vehicle system could
indicate a problem. Have the system inspected
and repaired and the fluid level checked. Add fluid
if needed.
(l) If you drive regularly under dusty conditions,
inspect the filter at each engine oil change.
(m) Visually inspect belt for fraying, excessive
cracks, or obvious damage. Replace belt if
necessary.
