120 UNDERSTANDING YOUR INSTRUMENT PANEL If the parking brake is applied and the vehicle is in motion, the red BRAKE warning light will "flash" and a chime will sound. The operation of the BRAKE warning light can be checked by turning the ignition switch from the OFF position to the ON position. The light should illuminate for approximately two seconds. The light should then turn off unless the parking brake is applied or a brake fault is detected. If the light does not illuminate, have the light inspected by an authorized dealer. 23. Low Fuel Warning Light When the fuel level reaches approximately 2 U.S. Gallons (7.6L) this light will come on and remain on until fuel is added. The "Low Fuel Warning Light" may turn on and off again, especially during and after hard braking, accelerations, or turns. This occurs due to the shifting of the fuel in the tank. 24. Fuel Cap Indicator This symbol indicates the side of the vehicle where the fuel cap is located. 25. Fuel Gauge The pointer shows the level of fuel in the fuel tank. When the fuel gauge pointer initially moves to E, for your safety, approximately 2 U.S. Gallons (7.6L) of fuel remain. NOTE: When the ignition switch is turned to OFF, the fuel gauge, voltmeter, oil pressure and temperature gauges may not show accurate readings. When the engine is not running, turn the ignition switch to ON to obtain accurate readings. ELECTRONIC DIGITAL CLOCK The clock and radio each use the display panel built into the radio. A digital readout shows the time in hours and minutes whenever the ignition switch is in the ON or ACC position and the time button is pressed. When the ignition switch is in the OFF position, or when the radio frequency is being displayed, time keeping is accurately maintained.
