the vehicle is mainly driven under one or more of these
conditions:

can be complex; you should have your dealer perform
this service. See Engine Coolant on page 5-25 for
what to use. Inspect hoses. Clean radiator, condenser,
pressure cap, and filler neck. Pressure test the
cooling system and pressure cap.
(j) Check throttle system for interference or 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) For supercharged engines only: Have your dealer
check the supercharger oil level and add the proper
supercharger oil as needed (or every 36 months,
whichever occurs first). See Recommended Fluids
and Lubricants on page 6-12.
(m) If you drive regularly under dusty conditions, inspect
the filter at each engine oil change.
(n) Visually inspect belt for fraying, excessive cracks, or
obvious damage. Replace belt if necessary.
