LOW COOLANT: This message will appear when there is a low level of engine coolant. Have the cooling system serviced by a technician as soon as possible. See Engine Coolant on page 5-20. LOW FUEL: This message will appear when the fuel supply is less than 5 gallons (18.9 L) and the display is turned off. A single chime will also sound when this message is displayed. LOW OIL LEVEL: For correct operation of the low oil sensing system, your vehicle should be on a level surface. A false LOW OIL LEVEL message may appear if the vehicle is parked on a grade. The oil level sensing system does not check for actual oil level if the engine has been off for a short period of time, and the oil level is never checked while the engine is running. If the LOW OIL LEVEL message appears, and your vehicle has been parked on level ground with the engine off for at least 30 minutes, the oil level should be checked by observing the oil dipstick. Prior to checking the oil level, be sure the engine has been off for a few minutes and your vehicle is on a level surface. Then check the dipstick and add oil if necessary. See Engine Oil on page 5-13. LOW OIL PRESSURE: If this message appears while the engine is running, stop the engine and do not operate it until the cause of low oil pressure is corrected. Severe damage to the engine can result. A multiple chime will sound when this message is displayed. LOW VOLTAGE: This message will appear when the electrical system is charging less than 10 volts or if the battery has been drained. If this message appears immediately after starting, it is possible that the generator can still recharge the battery. The battery should recharge while driving but may take a few hours to do so. Consider using an auxiliary charger (be sure to follow the manufacturer's instructions) to boost the battery after returning home or to a final destination. If this message appears while driving or after starting your vehicle and stays on, have it checked immediately to determine the cause of this problem. To help the generator recharge the battery quickly, you can reduce the load on the electrical system by turning off the accessories. You can monitor battery voltage on the DIC by pressing the INFO button. The normal range is 11.5 to 15.5 volts. LOW WASHER FLUID: This message means that your vehicle is low on windshield washer fluid. See Windshield Washer Fluid on page 5-33. 3-62
