What does a dash light that looks like watering can mean on 2005 caravan?

The dash light that looks like a watering can on a 2005 Caravan is the windshield washer fluid level indicator. When the fluid level is low, the light will illuminate to remind you to refill the reservoir.

To refill the windshield washer fluid reservoir, open the hood of your Caravan and locate the reservoir. It is usually a translucent plastic container located near the base of the windshield. Unscrew the cap and add windshield washer fluid until the reservoir is full. Be sure to use a fluid that is specifically designed for use in windshield washer systems.

If the windshield washer fluid level indicator light remains illuminated after you have refilled the reservoir, there may be a problem with the fluid level sensor. You may need to have the sensor checked by a qualified mechanic.
