Multifunctional display (DIC system) (Chevrolet Tahoe 2)

The multifunction display is turned on when the ignition key is turned to the "OM" position, and the display will show the mode in which the display was operating before the engine was turned off.

The following information is displayed on the multifunction display:

Information messages.
Individual settings.
Odometer and trip meter readings.
Trip computer readings.
Tire pressure monitoring system readings.
Engine operation timer.
Engine oil life.

Switching modes and controlling the operation of the multifunctional display is carried out by pressing the buttons located on the steering wheel.

1. Pressing the button (A) alternately displays the odometer, trip meter, tire pressure monitoring system and engine run timer on the multifunction display.

a) Odometer and trip meters (the display shows the indicator "ODOMETER", "TRIP A" or "TRIP B").

The odometer shows the total mileage of the vehicle.
The trip meters show the distance traveled since the last time the meter was reset to zero.
The odometer is reset by pressing button (A) for a longer period of time when the multifunction display is in odometer mode.

b) Tire pressure monitoring system indication mode (the display shows the indicator "TIRE PRESSURES"). By pressing the button (D) on the steering wheel it is possible to view the pressure (kPa or psi) in each tire:

LF TIRE - pressure in the front left tire.
RF TIRE - pressure in the front right tire.
LR TIRE - pressure in the rear left tire.
RR TIRE - rear right tire pressure.

c) General timer (the display shows "TIMER"). Shows the time since the timer was last set to zero (not including the time at which the ignition was turned off). The timer is reset by pressing and holding the button (A).
d) Engine operation timer (the display shows the indication "ENGINE HOURS"). Shows the total number of engine operating hours.

2. When you press the button (B), the trip computer readings are displayed sequentially on the multi-function display (the approximate distance the car can travel on the remaining fuel in the tank, the amount of fuel used and the average fuel consumption) and engine oil resource.

a) Approximate distance the vehicle can travel on the remaining fuel in the tank (the display shows "RANGE"). The display is updated after each refueling and shows the approximate distance the vehicle can travel on the remaining fuel in the tank. When the fuel level is low, the display shows "LOW".
b) Amount of fuel used (the display shows "FUEL USED"). Shows the amount of fuel used since the last time the counter was set to zero. The counter is reset by pressing and holding the button (B).
c) Average fuel consumption (the display shows "AVG EcOn"). Displays the average fuel consumption (L/100 km).
d) Engine oil resource (the display shows the indicator "ENGINE OIL LIFE"). Each time after changing the engine oil, reset this counter to zero by pressing and holding the button (B). If the display shows "100%", then the counter was reset after changing the oil.

Informational messages

Possible information messages and explanations for them are provided in the table "Information messages of the DIC system multifunction display".

Note:

Information messages are displayed when certain conditions occur, regardless of the operating mode of the multifunction display.

If there are multiple information messages, they are displayed one after the other.

To remove the information message from the multifunction display, press any DIC button on the steering wheel. The message will be removed if the reason for its appearance does not require immediate action, but this does not mean that the reason has been eliminated.

An information message, the reason for which requires immediate action, cannot be removed.
