Maintenance and care
WINDSHIELD WIPER BLADES
Check the wiper blades at least twice a year or when they seem less
effective. Substances such as tree sap and some hot wax treatments used
by commercial car washes reduce the effectiveness of wiper blades.
In cold weather conditions, the wiper blades need to be thawed before
operating in order to prevent premature wear to the wiper blades. Before
operating the wiper blades in cold weather, refer to the Electric window
heaters section of the Controls and Features chapter.
Checking the wiper blades
If the wiper blades do not wipe properly, clean both the windshield and
wiper blades using undiluted windshield wiper solution or a mild
detergent. Rinse thoroughly with clean water. To avoid damaging the
blades, do not use fuel, kerosene, paint thinner or other solvents.
Changing the wiper blades
To replace the wiper blades:
1. Pull the passenger side wiper arm
away from the windshield into the
service position. Turn the blade at
an angle from the wiper arm.
