How This Section is Organized
The remainder of this section is divided into five parts:
"Part A: Scheduled Maintenance Services" shows
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 retailer's service department or another
qualified service center do these jobs.
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 are skilled enough to do some work on your
vehicle, you will probably 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: Periodic Maintenance Inspections"
explains important inspections that your retailer's
service department or another qualified service
center should perform.
"Part D: Recommended Fluids and Lubricants"
lists some recommended products 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 E: Maintenance Record" provides a place
for you to record the maintenance performed on your
vehicle. Whenever any maintenance is performed, be
sure to write it down in this part. This will help you
determine when your next maintenance should be done.
In addition, it is a good idea to keep your maintenance
receipts. They may be needed to qualify your vehicle
for warranty repairs.
