Your owner’s manual was written to cover most of
the questions you might ask about your CRF.
Any questions not answered in the owner’s manual
can be answered by your dealer. If your dealer
doesn’t have the answer right away, they will get it
for you.
If you have a difference of opinion with your
dealer, please remember that each dealership is
independently owned and operated. That’s why
it’s important to work to resolve any differences at
the dealership level.
