Vehicle Information Menu Item Descriptions

The following paragraphs contain a more detailed description of each menu item:

OUTSIDE TEMP: If you select this item, the current outside temperature is displayed at the top of the screen. It will be in either degrees Fahrenheit (°F) or degrees Celsius (°C) depending upon whether the system is set for English or metric units. If you wish to change the units, see DIC Main Menu .

MI TRIP A and B (KM TRIP A and B): For information on the trip odometers, see Trip Odometers .

MILES RANGE (KM RANGE): If you select this item, the approximate number of remaining miles or kilometers you can drive without refueling is displayed. This estimate is based on the current driving conditions and will change if the driving conditions change. For example, if you are driving in traffic making frequent stops, the display may read one number, but if you enter the freeway, the number may change even though you still have the same amount of gas in the gas tank. This is because different driving conditions produce different fuel economies. Generally, freeway driving produces better fuel economy than city driving. If your vehicle is low on fuel, the Fuel Level Low message will be displayed. See "Fuel Level Low" under DIC Warnings and Messages for more information.

MPG AVG (L/100 KM AVG): If you select this item, the approximate average miles per gallon (mpg) or liters per 100 kilometers (L/100 km) is displayed. This number is calculated based on the number of mpg (L/100 km) recorded since the last time this menu item was reset. To reset the MPG AVG (L/100 KM AVG), press the CLR button located to the right of the screen. The display will return to zero.

MPG INST (L/100 KM INST): If you select this item, the current fuel economy is displayed. This number reflects only the fuel economy that the vehicle has right now and will change frequently as driving conditions change. Unlike average fuel economy, this menu item cannot be reset.

GAL FUEL USED (L FUEL USED): If you select this item, the number of gallons or liters of fuel used since the last reset of this menu item is displayed. To reset GAL FUEL USED (L FUEL USED), press the CLR button located to the right of the screen. The display will return to zero.

AVG MPH (AVG KM/H): If you select this item, the average speed of the vehicle is displayed in miles per hour (mph) or kilometers per hour (km/h). This average is calculated based on the various vehicle speeds recorded since the last reset of this menu item. To reset AVG MPH (AVG KM/H), press the CLR button located to the right of the screen. The display will return to zero.

TIMER: If you select this item, a timing feature is displayed. The timer functions like a stopwatch in that you can record the time it takes to travel from one point to another. To turn on the timer, press the CLR button located to the right of the screen once. The display will read 00:00:00 TIMER ON and begin counting. To turn off the timer, press the CLR button again. When the timer is off, the display will show the timer value and TIMER OFF. The timing feature will stop. To reset the timer, turn off the timer and then press and hold the CLR button. The display will return to zero.

BATTERY VOLTS: If you select this item, the current battery voltage is displayed. If the voltage is in the normal range, the display will have OK after it. For example, the display may read 13.2 BATTERY VOLTS OK. If there is a problem with the battery charging system, there are four possible DIC messages that may be displayed. See DIC Warnings and Messages for more information.

ENGINE OIL LIFE: If you select this item, the percentage of remaining oil life is displayed. If you see 99% ENGINE OIL LIFE on the display, that means that 99% of the current oil life remains. When the oil life is depleted, the Change Engine Oil message will appear on the display. See your dealer for service. In addition to the engine oil life system monitoring the oil life, additional maintenance is recommended in the Maintenance Schedule in this manual. See Scheduled Maintenance and Engine Oil for more information. When you reset the Change Engine Oil message by clearing it from the display, you still must reset the engine oil life system separately. For more information on resetting the engine oil life system, see "How to Reset the Engine Oil Life System and the Oil Life Indicator" under Engine Oil Life System . If you clear the Change Engine Oil message from the display, it will not re-appear.

TRANS FLUID LIFE (Automatic Transmission): If you select this item, the percentage of remaining transmission fluid life is displayed. If you see 99% TRANS FLUID LIFE on the display, that means that 99% of the current transmission fluid life remains. When the transmission fluid life is depleted, the Change Trans Fluid message will appear on the display. You should change the transmission fluid as soon as possible. Be sure to keep a written record of the mileage and date of the fluid change so you will have it for future reference. See Scheduled Maintenance and Recommended Fluids and Lubricants for more information. When you reset the Change Trans Fluid message by clearing it from the display, you still must reset the transmission fluid life monitor separately. For more information on resetting the transmission fluid life monitor, see Automatic Transmission Fluid .

LF TIRE: If you select this item, the driver's side front tire pressure will be displayed. If the tire pressure is low, LOW will be displayed with this item. The pressure can be displayed in pounds per square inch (PSI) or kilopascals (KPA). To change the units, see DIC Main Menu DIC Main Menu .

RF TIRE: If you select this item, the passenger's side front tire pressure will be displayed. If the tire pressure is low, LOW will be displayed with this item. The pressure can be displayed in pounds per square inch (PSI) or kilopascals (KPA). To change the units, see DIC Main Menu DIC Main Menu .

RR TIRE: If you select this item, the passenger's side rear tire pressure will be displayed. If the tire pressure is low, LOW will be displayed with this item. The pressure can be displayed in pounds per square inch (PSI) or kilopascals (KPA). To change the units, see DIC Main Menu DIC Main Menu .

LR TIRE: If you select this item, the driver's side rear tire pressure will be displayed. If the tire pressure is low, LOW will be displayed with this item. The pressure can be displayed in pounds per square inch (PSI) or kilopascals (KPA). To change the units, see DIC Main Menu DIC Main Menu .

BLANK LINE: If you select this item, nothing is displayed at the top of the screen.
