AUTOMATIC LIGHT CONTROL ON This message displays when the automatic headlamps are turned on. See Exterior Lamps on page 3-12 for more information. That must be done at the OIL LIFE screen under the vehicle information menu. See "Oil Life" under DIC Operation and Displays on page 3-42 and Engine Oil Life System on page 5-20. BATTERY SAVER ACTIVE This message displays when the system detects that the battery voltage is dropping beyond a reasonable level. The battery saver system starts reducing certain features of the vehicle that you may be able to notice. At the point that the features are disabled, this message is displayed. It means that the vehicle is trying to save the charge in the battery. Turn off all unnecessary accessories to allow the battery to recharge. The normal battery voltage range is 11.5 to 15.5 volts. CHECK TIRE PRESSURE On vehicles with the Tire Pressure Monitor System (TPMS), this message displays when the pressure in one or more of the vehicle's tires needs to be checked. This message also displays LEFT FRONT, RIGHT FRONT, LEFT REAR, or RIGHT REAR to indicate which tire needs to be checked. You can receive more than one tire pressure message at a time. To read the other messages that may have been sent at the same time, press the set/reset button. If a tire pressure message appears on the DIC, stop as soon as you can. Have the tire pressures checked and set to those shown on the Tire Loading Information label. See Tires on page 5-53, Loading the Vehicle on page 4-20, and Inflation - Tire Pressure on page 5-60. The DIC also shows the tire pressure values. See DIC Operation and Displays on page 3-42. If the tire pressure is low, the low tire pressure warning light comes on. See Tire Pressure Light on page 3-35. CHANGE ENGINE OIL SOON This message displays when service is required for the vehicle. See your dealer/retailer. See Engine Oil on page 5-17 and Scheduled Maintenance on page 6-4 for more information. Acknowledging the CHANGE ENGINE OIL SOON message will not reset the OIL LIFE REMAINING. 3-50
