A service bulletin that outlines issues related to the LED display in climate control systems for Model 211 vehicles equipped with Code 581. It addresses difficulties in reading the display under certain light conditions due to the rain/light sensor. The document suggests that bright sunlight or high diffused light can cause the sensor to switch the display to 'Night' mode, impacting visibility. Adjustments involving the dimmer function are noted, but no part replacements are recommended.
