Trip Computer Oil Life Indicator This feature lets you know when to change the engine oil. It's based on the engine oil temperatures and your driving patterns. To see the display, press the information button several times until OIL LIFE appears. If you see 99% OIL LIFE, 99 percent of your current oil life remains. The DIC may display a CHANGE OIL NOW message. For more information, see Scheduled Maintenance on page 6-4. If you see CHANGE OIL NOW, it means the oil life is gone and you should change the oil right away. The system doesn't check how much oil you have, so you'll still have to check for that. To see how, see Engine Oil on page 5-13. When the oil is changed, you'll need to reset the system. See Engine Oil on page 5-13. Always keep a written record of the mileage and date when you changed your oil. Audio System(s) Notice: Before you add any sound equipment to your vehicle - like a tape player, CB radio, mobile telephone or two-way radio - be sure you can add what you want. If you can, it's very important to do it properly. Added sound equipment may interfere with the operation of your vehicle's engine, radio or other systems, and even damage them. Your vehicle's systems may interfere with the operation of sound equipment that has been added improperly. So, before adding sound equipment, check with your dealer and be sure to check federal rules covering mobile radio and telephone units. Your audio system has been designed to operate easily and to give years of listening pleasure. You will get the most enjoyment out of it if you acquaint yourself with it first. Figure out which radio you have in your vehicle, find out what your audio system can do and how to operate all of its controls to be sure you're getting the most out of the advanced engineering that went into it. Your vehicle has a feature called Retained Accessory Power (RAP). With RAP, you can play your audio system even after the ignition is turned off. See "Retained Accessory Power (RAP)" under Ignition Positions on page 2-19. 3-72
