delivery service. Check vent hose at transfer case for
kinks and proper installation. Check to be sure vent
hose is unobstructed, clear, and free of debris.
During any maintenance, if a power washer is used
to clean mud and dirt from the underbody, care
should be taken to not directly spray the transfer
case output seals. High pressure water can
overcome the seals and contaminate the transfer

of the transfer case and should be replaced.

fuel and vapor lines and hoses for proper hook-up,
routing, and condition. Check that the purge valve, if
the vehicle has one, works properly. Replace as
needed. An Emission Control Service. The U.S.
Environmental Protection Agency or the California
Air Resources Board has determined that the failure
to perform this maintenance item will not nullify the
emission warranty or limit recall liability prior to the
completion of the vehicle's useful life. We, however,
urge that all recommended maintenance services
be performed at the indicated intervals and the
maintenance be recorded.
