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.

Turn the ignition key to the "ON" position without starting the engine.

2 Press the button to the left of the display on the instrument panel twice within one second. The oil life status will be displayed on the panel -- this should be past the mileage due for the service interval if the wrench icon is illuminated

4 Press and hold the button to the left of the display again with one hand while turning the ignition key back to the "ON" position without starting the engine. The oil life status will show once again

Press the clock button..... Does the time show (at least for a little bit)? If so, then you probably have the Energy Saver function turned on. Here's how to turn that function off (and have your clock display the time all the time): Press and hold the Clock button. Hold it for 15 seconds. Somewhere around 7 to 10 seconds, the clock will display, then go out, then come back on again. By 15 seonds, the clock display should be on, and if you then let go of the clock button, it should stay on.

Does it appear momentarily when you press the clock key? If so, then you probably have the "energy-saver" feature turned on. To turn it off (so it "wastes" energy by displaying the clock all the time), press and hold that key. When you first press the key, the clock time will display... (Keep holding that key!) Then in about 7 seconds, the display will go blank.... (Keep holding that key!) Then in about 3 more seconds, the display will come back on. Now you can let go of that key, and the clock time will continue to display.
