Air filter element (PZEV)
Your vehicle is equipped with a long life air filter. The air filter is
designed to last the life of the vehicle. See your authorized dealer or a
qualified technician for replacement. The technician can check the
diagnostics system for the possibility of an excessively dirty air filter.
Changing the air filter element (Non-PZEV only)
1. Release the clamps that secure
the air filter housing cover.
2. Carefully separate the two halves
of the air filter housing.
3. Remove the air filter element
from the air filter housing.
4. Wipe the air filter housing and
cover clean to remove any dirt or
debris and to ensure good sealing.
5. Install a new air filter element. Be
careful not to crimp the filter element edges between the air filter
housing and cover. This could cause filter damage and allow unfiltered
air to enter the engine if not properly seated.
6. Replace the air filter housing cover and secure the clamps. Be sure
that the air cleaner cover tabs are engaged into the slots of the air
cleaner housing.
Note: Failure to use the correct air filter element may result in severe
engine damage. The customer warranty may be void for any damage to
the engine if the correct air filter element is not used.
