If you want to do some of your own service work, you'll
want to get the proper service manual. It tells you much
more about how to service your vehicle than this manual
can.
To
order the proper service manual, see "Service
and Owner Publications" in the Index.
Your vehicle has an air bag system. Before attempting to
do your own service work, see "Servicing Your Air
Bag-Equipped Vehicle" in the Index.
You should keep a record with all parts receipts and list
the mileage and the date of any service work you
perform. See "Maintenance Record" in the Index.
You can be injured and your vehicle could be
damaged if
you
try to do service work on a
vehicle without knowing enough about it.
Be sure you have sufficient knowledge,
experience, and the proper replacement
parts and tools before you attempt any
vehicle maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. "English" and "metric"
fasteners can be easily confused. If you use
the wrong fasteners, parts can later break
or fall off. You could be hurt.
