• Set up your audio system by presetting your favorite radio stations, setting the tone, and adjusting the speakers. Then, when driving conditions permit, you can tune to your favorite radio stations using the presets and steering wheel controls if the vehicle has them. Notice: Before adding any sound equipment to your vehicle, such as an audio system, CD player, CB radio, mobile telephone, or two-way radio, make sure that it can be added by checking with your dealer. Also, check federal rules covering mobile radio and telephone units. If sound equipment can be added, it is 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. Your vehicle has a feature called Retained Accessory Power (RAP). With RAP, the audio system can be played even after the ignition is turned off. See Retained Accessory Power (RAP) on page 113 for more information. Setting the Time (Without Date Display) If your vehicle has an AM/FM base radio with a single CD player and preset buttons numbered one through six, the radio will have a clock button for setting the time. You can set the time by following these steps: 1. Press the clock button until the hour numbers begin flashing on the display. Press the clock button a second time and the minute numbers will begin flashing on the display. 2. While either the hour or the minute numbers are flashing, turn the tune knob, located on the upper right side of the radio, clockwise or counterclockwise to increase or decrease the time. Instead of using the tune knob, you can also press the SEEK, FWD (forward), or REV (reverse) buttons to adjust the time. 3. Press the clock button again until the clock display stops flashing to set the currently displayed time; otherwise, the flashing will stop after five seconds and the current time displayed will be automatically set. 214
