Maintenance and care

Changing the air filter element

1. Loosen the clamp that secures
the air filter element in place.
2. Carefully separate the two halves
of the air filter housing.
3. Remove the air filter element
from the open end of the air filter
housing.
4. Install a new air filter element. Be
careful not to crimp the filter
element edges between the air filter
housing. This could cause filter
damage and allow unmetered air to
enter the engine if not properly seated.
5. Replace the two halves of the air filter housing and secure the clamp.

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.

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.
