Ford 1997 Crown Victoria Manual page 232

not use fuel, kerosene, paint thinner, or other
solvents to clean your wiper blades. These will
damage your blades.
To make reaching the wiper blades easy, simply
turn the ignition to the ACC position and turn
your wipers on. Wait for them to reach a
vertical position and turn the ignition to the OFF
position. Do not move the wipers manually.
Manually moving the wipers across the
windshield may damage them.
Wiper blade replacement
If the wiper blades still do not work properly
after you clean them, you may need to replace
the wiper blade assembly or the blade element.
When replacing the wiper blade assembly, blade
refill, or wiper arm always use a Motorcraft part
or equivalent. To replace the blades, follow the
instructions that come with them.
Tires
Checking Tire Pressure
Use an accurate tire pressure gauge.
Check the tire pressure when tires are cold,
after the vehicle has been parked for at least
one hour or has been driven less than 3 miles
(5 km).
Adjust tire pressure to recommended
specifications found on the Safety Compliance
Certification Label.
Improperly inflated tires can affect vehicle
handling and can fail suddenly, possibly
resulting in loss of vehicle control.
