Chrysler 2007 300 - Manual (Page 114)

NOTE: The headlight washers will operate on the first
spray of the windshield washer and then every fourth
spray after that.
Adding Washer Fluid
The headlight washer and windshield washer share the
same fluid reservoir. The reservoir is located in the front
of the engine compartment on the passenger side of the
vehicle. Be sure to check the fluid level in the reservoir at
regular intervals. Fill the reservoir with windshield
washer solvent (not radiator antifreeze) and operate the
system for a few seconds to flush out the residual water.
WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around
the washer solution.
