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. See Doing Your
Own Service Work on page 245.
If you want to purchase service information,
see Service Publications Ordering Information
on page 415.
"Part B: Owner Checks and Services"
tells you what should be checked and when.
It also explains what you can easily do to
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.

you to record and keep track of the maintenance
performed on your vehicle. Keep your
