6.5 Unscrew the cap on the power steering fluid reservoir and 7.2 Use a tire tread depth indicator to monitor tire wear-they
check the fluid level on the dipstick are available at auto parts stores and service stations and cost
very little

7.3 This chart will help you determine the condition of the tires, the probable cause(s) of
abnbrmai wear and the corrective action necessary
5 Twist off the reservoir cap which has a built-in dipstick attached to it
(see illustration).
Wipe off the dipstick with a clean rag, reinstall it and re-
move it to get an accurate reading. The fluid level should be between the
MIN and MAX marks on the dipstick.
6 If additional fluid is required, pour the specified type directly into the
reservoir, using a funnel to prevent spills.
7 If the reservoir requires frequent fluid additions, ail power steering
hoses, hoseconnectionsandthepowersteeringpumpshould becarefully
checked for leaks.
7 Tire and tire pressure checks
Refer to illustrations 7.2, 7.3, 7.4a, 7.4b and 7.8
1 Periodic inspection of the tires may spare you the inconvenience of
being stranded with a flat tire. It can also provide you with vital information
regarding possible problems in the steering and suspension systems be-
fore major damage occurs.
2 The original tireson this vehicle are equipped with wear indicator bars
that will appear when tread depth reaches a predetermined limit, usually
i/l 6-inch, but they don’t appear until the tires are worn out. Tread wear
can be monitored with a simple, inexpensive device known as a tread
depth indicator (see
illustration).
3 Note any abnormal tread wear (see
illustration).
Tread pattern irreg-
ularities such as cupping, flat spots and more wear on one side than the
other are indications of front end alignment and/or balance problems. If
any of these conditions are noted, take the vehicle to a tire shop or service
station to correct the problem.
4 Look closely for cuts, punctures and embedded nails or tacks. Some-
times a tire will hold air pressure for a short time or leak down very slowly
after a nail has embedded itself in the tread. If a slow leak persists, check
the valve stem core to make sure it’s tight (see
illustration).
Examine the
tread for an object that may have embedded itself in the tire or for a “plug”
