This feature helps the driver determine such things as outside temperature, travel range, average speed, fuel consumption, and travel distance You can also set speed limit warnings and a timer with the OBC. The features are quite handy, unless you do not know how to access and use the features. Once you get the hang of using these features, you should be able to use them with ease.

    Check the outside temperature by hitting the "TEMP" button. This is found below the digital clock in your E36. As a safety feature, if the outside temperature drops below 3.06 degrees Celsius, the clock will automatically display and flash the temperature for eight seconds. This helps to indicate the possibility of ice on the roads.

    Use the "RANGE" button if you want to know the estimated travel range. This feature takes the amount of remaining fuel and estimates how much farther you can travel with that amount. To access this calculation, press the "RANGE" button. If you see a "+" and a number, it is telling you the range is still being calculated. If you see three flashing segments in the screen, it is telling you that you have less than nine miles (15km), so you should refuel as soon as you can. Your OBC will register the new fuel amount when you add more than 1.2 gallons (4 litres) and restart the car.

    Determine average speed by first parking your car and setting the speed calculation in this stationary position. Press the "SPEED" button and then press the "SET/RES" button on the bottom right corner. When you want to know the average speed at any given time, just press the "SPEED" button.
