If this message appears and stays on while driving or after starting your vehicle, 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 (SKIP) button. The normal range is 11.5 to 15.5 volts. CHANGE ENGINE OIL - 82: This means that the life of the engine oil has expired and it should be changed within 200 miles (322 km). See "Engine Oil" and "Filter Recommendations" in the Maintenance Schedule booklet. After an oil change, the Oil Life Indicator must be reset. See "Oil Life Indicator, How to Reset" in the Index. CHANGE TRANS FLUID - 47: This message will appear when it is time to replace the transaxle fluid. See the Maintenance Schedule booklet for the proper fluid and change intervals. CHECK BRAKE FLUID LEVEL - 37: This message will display if the ignition is in RUN to inform the driver that the brake fluid level is low. Have the brake system serviced by a technician as soon as possible. See "Brake System Warning Light" in the Index. CHECK COOLANT LEVEL - 2: 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. CHECK FUEL GAUGE - 39: This message will appear when the fuel supply is less than 3.5 gallons (13.2 L) remaining. A single chime will also sound when this message is displayed. CHECK GAS CAP - 61: This message will appear if the gas cap has not been fully tightened. You should recheck your gas cap to ensure that it's fully tightened. CHECK OIL LEVEL - 36: For correct operation of the low oil sensing system, your vehicle should be on a level surface. A false CHECK OIL LEVEL message may appear if the vehicle is parked on grades. 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 sensed while the engine is running. If the CHECK 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 five minutes and your vehicle is on a level surface. Then check the dipstick and add oil if necessary. See "Engine Oil" in the Index. 2-79
