.Evaporative control system inspection. Check all
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.

.Four‐wheel drive only: Transfer case fluid change
(normal service). Check vent hose at transfer
case for kinks and proper installation. Check to
be sure vent hose is unobstructed, clear, and free

spray the transfer case output seals. High pressure
water can overcome the seals and contaminate
the transfer case fluid. Contaminated fluid will
decrease the life of the transfer case and should
be replaced.
