Also , safety and environmental concerns p lace very strict
limits on the nature of repairs and adjustments to engine and trans ­

abil ity and safe ty of the vehicle and its many sy stems .
Im proper maintena nce, adjustments and repairs can impa ir the
operation and reliability of your vehicle and even void your vehicle
wa rranty. T here fore, proof o f servic ing in acc orda nce with the main­
tenance schedule may be a condition for upholding a possib le
warranty cla im made with in t he war ran ty per iod .
Above all, operationa l safety can be adversely affected, creating
unnecessary risks for you and your passengers.
