How This Section is Organized
This maintenance schedule is divided into four parts:
“Part A: Scheduled Maintenance Services” explains
what to have done and how often. Some of these
services can be complex, so unless you are technically
qualified and have the necessary equipment, you should
let your dealer’s service department or another qualified
service center do these jobs.
CAUTION:
Performing maintenance work on a vehicle can
be dangerous. In trying to do some jobs, you can
be seriously injured. Do your own maintenance
work only if you have the required know
-
how
and the proper tools and equipment for the job.
If you have any doubt, have a qualified
technician do the work.
If you want to get the service information, see “Service
and Owner Publications” in the Index.
“Part B: Owner Checks and Services” tells you
what should be checked and when. It also explains what
you can easily do to help keep your vehicle in good
condition.
“Part C: Recommended Fluids and Lubricants” lists
some recommended products necessary to help keep
your vehicle properly maintained. These products, or
their equivalents, should be used whether you do the
work yourself or have it done.
“Part D: Maintenance Record” is a place for
you to record and keep track of the maintenance
performed on your vehicle. Keep your maintenance
receipts. They may be needed to qualify your vehicle
for warranty repairs.
