Your vehicle manufacturer has listed some required maintenance --- care that must be performed, or the warranty for the vehicle lapses due to lack of following the schedule. This required maintenance is necessary to avoid engine wear and breakdown due to lack of car care.
Regular maintenance on a vehicle insures that the vehicle will continue to perform as it is supposed to. Regular oil changes, fluid checks, brake adjustments, and other checks insure that your new car is safe and will continue to render performance for you, the owner. Follow your maintenance schedule, and your vehicle will retain its value for years to come. That is why maintenance is so important.
