BATTERY VOLTAGE LOW This symbol appears with this message. The normal battery voltage range is 11.5 to 15.5 volts. To monitor battery voltage on the DIC, press the information button until BATTERY VOLTS displays. CHANGE ENGINE OIL SOON This message displays when the engine oil needs to be changed. See your dealer/retailer. See Engine Oil on page 6‑18 and Scheduled Maintenance on page 7‑3 for more information. This message displays when the electrical system is charging less than 10 volts or the battery has been drained. If this message appears immediately after starting the engine, 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 to boost the battery after returning home or to a final destination. Follow the manufacturer's instructions. 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, reduce the load on the electrical system by turning off the accessories. After resetting the CHANGE ENGINE OIL SOON message by clearing it from the display, reset the engine oil life system separately. For more information on resetting the engine oil life system, see Engine Oil Life System on page 6‑21. CHECK BRAKE FLUID This message displays if the ignition is on to inform the driver that the brake fluid level is low. Have the brake system serviced by your dealer/retailer as soon as possible. See Brake System Warning Light on page 4‑58 for more information. CHECK GAS CAP This message displays when the fuel cap has not been fully tightened. Recheck the fuel cap to ensure that it is on and tightened properly. 4-78
