Owner’s Responsibility
Maintenance service and record retention are the owner’s responsibility.
You should retain documents that show proper maintenance has been performed on your vehicle in accordance with the scheduled maintenance service charts shown on the following pages. You need this information to establish your compliance with the servicing and maintenance requirements of your vehicle warranties.
Detailed warranty information is provided in your Owner's Handbook & Warranty Information booklet.
Repairs and adjustments required as a result of improper maintenance or a lack of required maintenance are not covered.
Owner Maintenance Precautions
Inadequate, incomplete or insufficient servicing may result in operational problems with your vehicle that could lead to vehicle damage, an accident, or personal injury. This chapter provides instructions only for the maintenance items that are easy to perform. Several procedures can be done only by an authorized HYUNDAI dealer with special tools.
Your vehicle should not be modified in any way. Such modifications may adversely affect the performance, safety or durability of your vehicle and may, in addition, violate conditions of the limited warranties covering the vehicle.
Certain modifications may also be in violation of regulations established by the U.S. Department of Transportation and other federal or state agencies.
