11-38 Maintenance and service ! Installing the wheel cover Aluminum wheels Aluminum wheels can be scratched and damaged easily. Handle them carefully to maintain their appearance, performance, and safety. . When any of the wheels are removed and replaced for tire rotation or to change a flat tire, always check the tightness of the wheel nuts after driving approximately 600 miles (1,000 km). If any nut is loose, tighten it to the specified torque. . Never apply oil to the threaded parts, wheel nuts, or tapered surface of the wheel. . Never let the wheel rub against sharp protrusions or curbs. . When wheel nuts, balance weights, or the center cap is replaced, be sure to replace them with genuine SUBARU parts designed for aluminum wheels. Windshield washer fluid Align the valve with the valve hole in the cover, then fit the cover on the wheel by tapping your hand evenly around the circumference of the cover. If you spray washer fluid on the windshield but the supply of washer fluid appears to diminish, check the level of washer fluid in the tank.
