These messages will appear if there is a problem sensed in one of your vehicle's systems. Vehicles that are first sold in Canada will have a number after each message. This number helps to identify the problem. You must then press INFO or INFO RESET to clear the display screen for further use. However, be sure to take any message that appears on the display screen seriously and remember that pressing the INFO or INFO RESET button will only make the message disappear, not the problem.

DIC messages can also be displayed in French, German, Spanish and Japanese. Contact your dealer to have the language display adjusted for your vehicle.

BATTERY NOT CHARGING - 7: This message will appear if the battery is not being charged. Have the electrical system checked by your dealership at your earliest convenience.

BATTERY SAVER ACTIVE - 27: This message is displayed when the vehicle has detected that the battery voltage is dropping beyond a reasonable point. The battery saver system will start reducing certain features of the vehicle that you may not be able to notice. At the point that features are disabled, this message is displayed. It means that the vehicle is trying to save the charge in the battery. Turn off unnecessary accessories to allow the battery to recharge.

BATTERY VOLTAGE HIGH - 8: This message shows that the electrical charging system is overcharging (more than 16 volts). To avoid being stranded, have the electrical system checked by your dealership. You can reduce the charging overload by using the accessories. Turn on the lamps and radio, set the climate control on AUTO and the fan speed on HI, and turn the rear window defogger on. You can monitor battery voltage on the DIC by pressing the INFO button. The normal range is 11.5 to 15.5 volts when the engine is running.

BATTERY VOLTAGE LOW - 6: 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.

CHANGE ENGINE OIL - 82: This means that the life of the engine oil has expired. See Scheduled Maintenance . After an oil change, the Oil Life Indicator must be reset. See Oil Life Indicator . See Engine Oil .

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 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 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 a few minutes and your vehicle is on a level surface. Then check the dipstick and add oil if necessary. See Engine Oil .

CHECK TIRE PRESSURE - 144: This message is displayed when the Tire Pressure Monitor (TPM) system detects a low or high tire pressure condition in one or more of the road tires. By pressing the INFO button up or down, the DIC display will show which tire or tires do not have the correct inflation pressure. A "LOW TIRE" condition exists when the tire's air pressure is under 25 psi (172 kPa) and a "HIGH TIRE" condition exists when the tire's air pressure is above 38 psi (262 kPa). The system will display the air pressure, the tire location (LF, RF, RR or LR) and if the air pressure is low or high. The tire pressure information is available in English or metric measurements. For example, a driver's side front tire that is low may be shown as: 22 PSI LF TIRE LOW. The correct tire inflation pressure should be set to those shown on the Tire Loading-Information Label, located on the rear edge of the driver's door. For more information regarding proper tire inflation, see Inflation - Tire Pressure . If a tire is low, you should stop as soon as possible and inspect your tire(s) for damage. If a tire is flat, see If a Tire Goes Flat . Once the TPM system detects the low or high tire pressure condition, the message CHECK TIRE PRESSURE will be displayed whenever you start the engine. To remove or clear the CHECK TIRE PRESSURE message, you will need to set the tire(s) to the proper tire pressure. See Inflation - Tire Pressure .

Caution: When the CHECK TIRE PRESSURE message is displayed on the Driver Information Center and the tire pressure is low, your vehicle's handling capabilities will be reduced during severe maneuvers. If you drive too fast, you could lose control of your vehicle. You or others could be injured. Don't drive over 55 mph (90 km/h) when the tire pressure is low. Drive cautiously and correct the tire pressure as soon as you can.
