and cracking. SeeScheduled Maintenance on page 7-3
for more information on wiper blade inspection.
Replacement blades come in different types and are
removed in different ways. To remove the type with a
release clip, do the following:
1. Lift the wiper arm until it locks into a vertical
position.
2. Press down on the blade assembly pivot locking
tab. Pull down on the blade assembly to release it
from the wiper arm hook.3. The insert has two notches at one end that are
locked by bottom claws of the blade assembly.
At the notched end, pull the insert from the blade
assembly.
4. To install the new wiper insert, slide the notched
end last, into the end with two blade claws. Then
slide the insert all the way through the blade claws
at the opposite end.
5. Make sure that the notches are locked by the
bottom claws. Make sure that all other claws
are properly locked on both sides of the insert slot.
6. Put the blade assembly pivot in the wiper arm
hook. Pull it up until the pivot locking tab locks
in the hook slot.
7. Carefully lower the wiper arm and blade assembly
into the windshield.

Windshield and Wiper Blades
Clean the outside of the windshield with glass cleaner.
Clean the rubber blades using a lint free cloth or
paper towel soaked with windshield washer fluid or a
mild detergent. Wash the windshield thoroughly
when cleaning the blades. Bugs, road grime, sap, and a
buildup of vehicle wash/wax treatments may cause
wiper streaking. Replace the wiper blades if they are
worn or damaged.
Wipers can be damaged by:
•Extreme dusty conditions
•Sand and salt
•Heat and sun
•Snow and ice, without proper removal
Aluminum Wheels
Notice:Using strong soaps, chemicals, abrasive
polishes, cleaners, brushes, or cleaners that contain
acid on aluminum or chrome-plated wheels, could
damage the surface of the wheel(s). The repairs
would not be covered by the vehicle warranty. Use
only approved cleaners on aluminum or
chrome-plated wheels.Keep the wheels clean using a soft clean cloth with mild
soap and water. Rinse with clean water. After rinsing
thoroughly, dry with a soft clean towel. A wax may then
be applied.
Notice:Using chrome polish on aluminum wheels
could damage the wheels. The repairs would not
be covered by the vehicle warranty. Use chrome
polish on chrome wheels only.
The surface of these wheels is similar to the painted
surface of the vehicle. Do not use strong soaps,
chemicals, abrasive polishes, abrasive cleaners,
cleaners with acid, or abrasive cleaning brushes on
them because the surface could be damaged. Do not
use chrome polish on aluminum wheels.
Notice:Driving the vehicle through an automatic
car wash that has silicone carbide tire cleaning
brushes, could damage the aluminum or
chrome-plated wheels. The repairs would not be
covered by the vehicle warranty. Never drive
a vehicle that has aluminum or chrome-plated
wheels through an automatic car wash that uses
silicone carbide tire cleaning brushes.
