vide you with additional information.
!Using engine oils and oil filters of specifica-
tion other than those expressly required for the

filter at change intervals longer than those called
for by the Maintenance System will result in en-
gine or emission control system damage not cov-

Warning!G
During vehicle operation, the boiling point of
the brake fluid is continuously reduced
through the absorption of moisture from the
atmosphere. Under extremely strenuous op-
erating conditions, this moisture content
can lead to the formation of bubbles in the
system, thus reducing the system’s efficien-
cy.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle’s Mainte-
nance Booklet for replacement interval.
