Service and Maintenance 11-5
. All‐wheel drive only: Transfer
case fluid change (severe
service) for vehicles mainly
driven when frequently towing a
trailer, or used for taxi, police,
or delivery service. 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 case
fluid. Contaminated fluid will
decrease the life of the transfer
case and should be replaced.
. 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.
