# Multi function clock description

The multi function clock was standard on 318i and 325iX, optional on all other vehicles.

There is a switch on the rear of the unit that allows the multi function to be switched between 12 hour clock with °F ; 12 hour clock with °C and 24 hour clock and °C

Display brightness is automatically controlled by a photo- sensitive transistor, depending on the amount of outside light.

### Functions

#### Hour and Date entries

The time or date may be entered by pushing the appropriate HOUR or DATE button for three seconds until a flashing dot appears on the display. (Note: the time function is shown by a clock symbol and the date function by the letters DAT.)

If time is to be entered, push the h/DAT button to set the hour and the min/DAT button to set the minutes. By holding the button down, the display will increase by 1 digit every half second. The date function is entered the same way. To start the clock running , push the HOUR button.

To start the date function, push the DATE button. The flashing dot will also stop. The date display disregards leap years and must be corrected manually.

#### MEMO

When the MEMO button is pushed, the time reminder is activated and an audible signal, consisting of 3 beeps, will sound 15 seconds before each full hour. This function is indicated in the display of the letters ME

#### TEMP

The outside temperature is displayed when the TEMP button is pressed. At ignition key position 1 and beyond, a warning signal sounds when the outside temp falls below 37° F. At the same time, the °F and dot on the display will flash for 10 seconds.

If another function is selected during this period and then the temperature display is selected again, only the flashing visual warning occurs, the acoustical warning signal will not sound. However, if the temperature since the last warning has risen above 43°F and then dropped again below 37°F, the visual and acoustical warning signals are repeated.

To prevent incorrect temperature displays for instance, from exhaust or engine heat in a stop and go traffic situation, the temperature display is connected to a movement identifying signal from the speedometer.l As soon as the signal for movement falls below 4 mph, the temperature shown in the display is locked in. As the speed increases above 4 mph ( and more than 30 seconds have passed), the temperature function will go into its normal sensing mode.

The temperature range that can be presented on the display is from -49°F to +113° F
