Vehicle Information Menu Item Descriptions

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

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

OUTSIDE TEMP/Outside Air Temperature: If you select this item, the current outside temperature is displayed at the top of the screen. It will be in either degrees Fahrenheit or degrees Celsius depending upon whether the system is set for English or metric units. If you wish to change the units on the Base audio system, see DIC Main Menu . If you have the optional Navigation System and wish to change the units, see "Setup Menu" in the Index of the CTS Entertainment and Navigation System owner's manual.

MI TRIP A and B/Trip Odometer A and B: For information on the trip odometers, see "Trip Odometers" under Speedometer and Odometer .

MPG AVG/Average Fuel Economy: 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 using the Base audio system, press the CLR button located to the right of the screen. The display will return to zero. To reset the Average Fuel Economy using the Navigation system, press and hold the multi-function button that corresponds to the Reset prompt in the upper right of the display. The display will return to zero.

MPG INST/Instantaneous Fuel Economy: 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/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 using the Base audio system, press the CLR button located to the right of the screen. The display will return to zero. To reset Fuel Used using the Navigation system, press and hold the multi-function button that corresponds to the Reset prompt in the upper right of the display. The display will return to zero.

MILES RANGE/Fuel 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 Low Fuel Level message will be displayed. See "Low Fuel Level Message" under DIC Warnings and Messages for more information.

AVG MPH/Average Vehicle Speed: 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 using the Base audio system, press the CLR button located to the right of the screen. The display will return to zero. To reset the Average Vehicle Speed using the Navigation system, press and hold the multi-function button that corresponds to the Reset prompt in the upper right of the display. The display will return to zero.

TIMER/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 use the timer, you must first turn it on. To turn on the timer using the Base audio system, press the CLR button located to the right of the screen once. To turn on the timer using the Navigation system, press the multi-function button next to the On/Off menu item in the upper right of the display. The display for both systems will read 00:00:00 TIMER ON and begin counting. Press the button(s) again to turn the timer off. When the timer is off, the display will show the timer value and TIMER OFF. The timing feature will stop. To reset the timer using the Base audio system, turn off the timer and then press and hold the CLR button. The display will return to zero. To reset the timer using the Navigation system press and hold the multi-function button next to the Reset prompt in the upper right of the display. The display will return to zero.

BATTERY VOLTS/Battery Voltage: 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/Engine Oil Life: If you select this item, the percentage of remaining oil life is displayed. If you see 99% 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 Engine Oil and Scheduled Maintenance 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 monitor separately. For more information on resetting the engine oil life monitor, see Engine Oil .

TRANS FLUID LIFE/Transmission 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 Transmission Fluid message will appear on the display. You should change the transmission fluid as soon as possible within 200 miles. Be sure to keep a written record of the mileage and date of the fluid change so you will have it for future reference. When you reset the Change Transmission 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 .
