SUGGESTIONS FOR OBTAINING SERVICE FOR
YOUR VEHICLE
Prepare For The Appointment
If you’re 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
If you list a number of items, and you must have your
vehicle by the end of the day, discuss the situation with
the service advisor and list the items in order of priority.
At many dealers you may obtain a rental vehicle at a
minimal daily charge. If you need a rental, it is advisable
to make these arrangements when you call for an ap-
pointment.
IF YOU NEED ASSISTANCE
The manufacturer and its dealers are vitally interested in
your satisfaction. We want you to be happy with our
products and services.
Warranty service must be done by an authorized
Chrysler, Dodge, or Jeep dealer. We strongly recommend
that you take your vehicle to your selling dealer. They
know you and your vehicle best, and are most concerned
that you get prompt and high quality service. The
manufacturer’s dealers have the facilities, factory-trained
