Owner maintenance precautions
Improper or incomplete service may result in problems. This section gives instructions only for the maintenance items that are easy to perform. As explained earlier in this section, several procedures can be done only by an authorized HYUNDAI dealer with special tools.
NOTICE
Improper owner maintenance during the warranty period may affect warranty coverage. For details, read the separate Owner’s Handbook & Warranty Information booklet provided with the vehicle. If you're unsure about any servicing or maintenance procedure, have it done by an authorized HYUNDAI dealer.
WARNING - Maintenance work
• Performing maintenance work on a vehicle can be dangerous. You can be seriously injured while performing some maintenance procedures. If you lack sufficient knowledge and experience or the proper tools and equipment to do the work, have it done by an authorized HYUNDAI dealer.
• Working under the hood with the engine running is dangerous. It becomes even more dangerous when you wear jewelry or loose clothing. These can become entangled in moving parts and result in injury. Therefore, if you must run the engine while working under the hood, make certain that you remove all jewelry (especially rings, bracelets, watches, and necklaces) and all neckties, scarves, and similar loose clothing before getting near the engine or cooling fans.
