Prepare For The Appointment
If you are having warranty work done, be sure to have
the right papers with you. Take your warranty folder. All
work to be performed may not be covered by the
warranty. Discuss additional charges with the service
manager. Keep a maintenance log of your vehicle’s
service history. This can often provide a clue to the
current problem.
Prepare A List
Make a written list of your vehicle’s problems or the
specific work you want done. If you’ve had an accident
or work done that is not on your maintenance log, let the
service advisor know. Be Reasonable With Requests

vehicle by the end of the day, discuss the situation with
the service advisor and list the items in order of priority.

vehicle at a minimal daily charge. If you need a rental, it
is advisable to make these arrangements when you call
