The Driver Information Center (DIC) has different displays which can be accessed by pressing the DIC buttons located on the instrument panel, to the left of the steering wheel.

Trip/Fuel: Press this button to scroll through the trip and fuel displays. See "Trip/Fuel Display Menu Items" following for more information on these displays.

Vehicle Information: Press this button to scroll through the vehicle information displays. See "Vehicle Information Display Menu Items" following for more information on these displays.

Customization: Press this button to scroll through each of the customization features. See DIC Vehicle Customization for more information on the customization features.

Set/Reset: Press this button to reset certain DIC features and to acknowledge DIC warning messages and clear them from the DIC display.

Menu Up/Down: Press this button to scroll up and down the menu items.

Trip/Fuel Display Menu Items

(Trip/Fuel): The following display menu items can be displayed by pressing the trip/fuel button:

TRIP A or TRIP B

These displays show the current distance traveled since the last reset for each trip odometer in either miles (mi) or kilometers (km). Both odometers can be used at the same time. Each trip odometer can be reset to zero separately by pressing and holding the set/reset button for a few seconds while the desired trip odometer is displayed.

FUEL RANGE

This display shows the approximate number of remaining miles (mi) or kilometers (km) you can drive without refilling your fuel tank. 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 and 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 fuel in the fuel tank. This is because different driving conditions produce different fuel economies. Generally, freeway driving produces better fuel economy than city driving.

Once the range drops below about 30 miles (48 km) remaining, the display will show FUEL RANGE LOW.

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.

AVERAGE ECONOMY (AFE)

This display shows the approximate average miles per gallon (mpg) or liters per 100 kilometers (L/100 km). This number is calculated based on the number of mpg (L/100 km) recorded since the last time this display was reset. To reset this display, press the set/reset button. The display will return to zero.

INST (Instantaneous) ECONOMY (IFE)

This display shows the current fuel economy in either miles per gallon (mpg) or liters per 100 kilometers (L/100 km). This number reflects only the fuel economy that the vehicle has right now and will change frequently as driving conditions change. Unlike average economy, this display cannot be reset.

FUEL USED

This display shows the number of gallons (gal) or liters (L) of fuel used since the last reset of this display. To reset this display, press the set/reset button. The display will return to zero.

TIMER ON/OFF

This display can be used like a stopwatch. You can record the time it takes to travel from one point to another. To access the timer, press the trip/fuel button until 00:00:00 TIMER OFF displays.

To turn on the timer, press the set/reset button until TIMER ON displays. The timer will then start.

To turn off the timer, press the set/reset button again until TIMER OFF displays. The timer will stop and display the end timing value.

To reset the timer, press and hold the set/reset button after the timer has been stopped. The display will return to zero.

AVERAGE SPEED

This display shows the average speed of the vehicle in either 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 display. To reset this display, press the set/reset button. The display will return to zero.

BATTERY VOLTAGE

This display shows the current battery voltage. Your vehicle's charging system regulates voltage based on the state of the battery. The battery voltage may fluctuate when viewing this information on the DIC. This is normal.

If there is a problem with the battery charging system, the charging system light will illuminate and/or the DIC will display a message. See Charging System Light , DIC Warnings and Messages and Electric Power Management for more information.

Blank Display

This display shows no information.

Vehicle Information Display Menu Items

(Vehicle Information): The following display menu items can be displayed by pressing the vehicle information button:

OIL LIFE REMAINING

If the vehicle has this display, it shows the estimated oil life remaining. If you see 99% OIL LIFE REMAINING on the display, that means that 99% of the current oil life remains.

When the oil life is depleted, the CHANGE ENGINE OIL SOON message will appear on the display. You should change your oil as soon as possible. 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 .

Remember, you must reset the OIL LIFE yourself after each oil change. It will not reset itself. Also, be careful not to reset the OIL LIFE accidentally at any time other than when the oil has just been changed. It cannot be reset accurately until the next oil change. To reset the engine oil life system, See Engine Oil Life System . The display will show 100% when the system is reset.

UNITS

This display allows you to select between English or Metric units of measurement. Once in this display, press the set/reset button to select between ENGLISH or METRIC units.

PARKING ASSIST

If your vehicle has the Ultrasonic Rear Parking Assist (URPA) system, this display allows the system to be turned on or off. Once in this display, press the set/reset button to select between ON or OFF. If you choose ON, the system will be turned on. If you choose OFF, the system will be turned off. The URPA system automatically turns back on after each vehicle start. When the URPA system is turned off and the vehicle is shifted out of PARK (P), the DIC will display the PARKING ASSIST OFF message as a reminder that the system has been turned off. See DIC Warnings and Messages and Ultrasonic Rear Parking Assist (URPA) for more information.

FRONT TIRES or REAR TIRES

If your vehicle has a Tire Pressure Monitor (TPM) system, the pressure for each tire can be viewed in the DIC. The tire pressure will be shown in either pounds per square inch (psi) or kilopascals (kPa). Press the vehicle information button until the DIC shows the tire pressure for the front tires. Press the vehicle information button again to view the pressure for the rear tires.

If a low or high tire pressure condition is detected by the system while driving, a message advising you to check the pressure in a specific tire will appear in the display. See Inflation - Tire Pressure and DIC Warnings and Messages for more information.

RELEARN TIRE POSITIONS

If your vehicle has a Tire Pressure Monitor (TPM) system, after rotating the tires or after replacing a tire or sensor, the system must re-learn the tire positions. To re-learn the tire positions, see Tire Pressure Monitor System . See Tire Inspection and Rotation and DIC Warnings and Messages for more information.

RELEARN REMOTE KEY

This display allows you to match Remote Keyless Entry (RKE) transmitters to your vehicle. To match an RKE transmitter to your vehicle, do the following:

  1. Press the vehicle information button until PRESS TO RELEARN REMOTE KEY displays.
  2. Press the set/reset button until REMOTE KEY LEARNING ACTIVE is displayed.
  3. Press and hold the lock and unlock buttons on the first transmitter at the same time for about 15 seconds.
  4. On vehicles with memory recall seats, the first transmitter learned will match driver 1 and the second will match driver 2.

    A chime will sound indicating that the transmitter is matched.

  5. To match additional transmitters at this time, repeat Step 3.
  6. Each vehicle can have a maximum of eight transmitters matched to it.

  7. To exit the programming mode, you must cycle the key to OFF.

SPEEDOMETER

This display shows a digital speedometer in the DIC. The speed will be displayed in either miles per hour (mph) or kilometers per hour (km/h). Press the vehicle information button until the DIC shows the digital speedometer. To change the units from English to metric, see "UNITS" earlier in this section.
