You can be injured and the
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, the
proper replacement parts,
and tools before attempting
any vehicle
maintenance task.
Be sure to use the proper
nuts, bolts, and other
fasteners. Metric and English
fasteners can be easily
confused. If the wrong
fasteners are used, parts can
later break or fall off. You
could be hurt.
If doing some of your own service
work, use the proper service
manual. It tells you much more
about how to service the vehicle
than this manual can. To order the
proper service manual, see

This vehicle has an airbag system.
