Cadillac CTS - Manual (Page 167)

Headlamp Washer
If your vehicle has the high-intensity discharge
(HID) headlamps, your vehicle will also have
headlamp washers. The headlamp washers help
clear the headlamp lenses.
The headlamp washers
are located on the
inboard side of
the headlamp lenses.
The headlamps must be on in order to be washed.
If the headlamps are off, only the windshield will
be washed when the washer button is pressed.
To wash the headlamps, press the washer button
located at the end of the windshield wiper lever.
Both the headlamps and the windshield will be
washed.
See Windshield Washer on page 166 for more
information.
