Windshield Wipers And Washer - Mercury Grand Marquis 1997 Owner's Manual

To turn off the high beams, pull the lever
toward you until it latches. The high beam
indicator light turns off.
Flashing the Lights
To flash the headlamps, pull the lever toward
you for a moment and then release it. The
headlamps will flash whether the headlamp
knob is in the on or off position.

Windshield Wipers and Washer

To turn on the windshield wipers, the ignition
key must be turned to the ON or ACC position.
Rotate the end of the lever away from you to
activate the wipers. The first seven detents are
interval wipe positions, the eighth detent is the
LO position and the ninth detent is the HI
position.
To turn the wipers off, turn the knob toward
you to the OFF position.
Variable Interval Wipers
In addition to two speed wipers, your vehicle
has wipers that you can set to operate at
varying intervals. For example, you can set the
interval so they wipe less often when it drizzles
or more often in heavier rain.
