Low Washer Fluid Level Tone Alarm
WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
If 10 seconds have passed after ignition switch has been turned "ON," and then, washer fluid level switch remains at the position "ON" (alarms for washer fluid level getting low) for two seconds or more, ETACS-ECU makes buzzer sound. Buzzer sounds just once after setting ignition switch to the position "ON."
