All the indicator/warning lights are LEDs and are not replaceable. Critical warning indicators use two LEDs for safety. There are five conventional bulbs for the back lighting of the LCD which can be replaced if necessary.

The LCD provides:

6 digit total mileage.
4 digit trip mileage.
Manipulation DOT.
Outside temperature display.
20 digit read-out with reminder arrows.
Service Interval Indicator.
Automatic transmission selector position.
Automatic transmission driving program.

When KLR is switched on, mileage and temperature are displayed. All displays are illuminated from KL15.

The back lighting intensity of the LCD's is dependent on available light and is controlled by a photo-transistor in the lower left corner of the cluster. When the parking lights are switched on, the dash mounted dimmer wheel controls the intensity of the back lighting.
