Blade inspection

Commercial hot waxes applied by automatic car washes have been known to make the windshield difficult to clean.
Contamination of either the windshield or the wiper blades with foreign matter can reduce the effectiveness of the windshield wipers. Common sources of contamination are insects, tree sap, and hot wax treatments used by some commercial car washes. If the blades are not wiping properly, clean both the window and the blades with a good cleaner or mild detergent, and rinse thoroughly with clean water.
CAUTION - Wiper blades
To prevent damage to the wiper blades, do not use gasoline, kerosene, paint thinner, or other solvents on or near them.
Filter inspection The climate control air filter should be replaced according to the Maintenance Schedule. If the vehicle is operated in severely air-polluted cities or on dusty rough roads for a long period, it should be inspected more frequently and replaced earlier.
When the wipers no longer clean adequately, the blades may be worn or cracked, and require replacement. To prevent damage to the wiper arms or other components, do not attempt to move the wipers manually.

To equalize tread wear, it is recommended that the tires be rotated every 12,000 km (7,500 miles) or sooner if irregular wear develops. During rotation, check the tires for correct balance. When rotating tires, check for uneven wear and damage.
