GENERAL MAINTENANCE
These are some maintenance and inspection items which are considered to be the owner's responsibility.
They can be done by the owner or they can have them done at a service shop. These items include those
which should be checked on a daily basis, those which, in most cases, do not require (special) tools and
those which are considered to be reasonable for the owner to do. Items and procedures for general mainte-
nance are as follows.
1. GENERAL NOTES
Maintenance items may very from country and country. Check the owner's manual supplement in
which the maintenance schedule is shown.
Every service items in the periodic maintenance schedule must be performed.
Periodic maintenance service must be performed according to whichever interval in the periodic main-
tenance schedule occurs first, the odometer reading (miles) or the time interval (months).
Maintenance service after the last period should be performed at the same time interval as before un-
less otherwise noted.
Failure to do even one item an cause the engine to run poorly and increase exhaust emissions.
2. TIRES
(a) Check the pressure with a gauge. If necessary, adjust.
(b) Check for cuts, damage or excessive wear.
3. WHEEL NUTS
When checking the tires, check the nuts for looseness or for missing nuts. If necessary, tighten them.
4. TIRE ROTATION
Check the owner's manual supplement in which the maintenance schedule is shown.
5. WINDSHIELD WIPER BLADES
Check for wear or cracks whenever they do not wipe clean. If necessary, replace.
6. FLUID LEAKS
(a) Check underneath for leaking fuel, oil, water or other fluid.
(b) If you smell gasoline fumes or notice any leak, have the cause found and corrected.
7. DOORS AND ENGINE HOOD
(a) Check that all doors and the tailgate operate smoothly, and that all larches lock securely.
(b) Check that the engine hood secondary latch secures the hood from opening when the primary latch
is released.
