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

assure your vehicle is fixed correctly and in a timely
manner.
This is why you should always talk to your dealer's
service manager first. Most matters can be resolved with
this process.
²If for some reason you are still not satisfied, talk to the
general manager or owner of the dealership. They
want to know if you need assistance.
²If your dealership is unable to resolve the concern, you
may contact the Manufacturer's Customer Center.

Center should include the following information:

DEPARTMENT OF TRANSPORTATION UNIFORM
TIRE QUALITY GRADES
The following describes the tire grading categories estab-
lished by the National highway Traffic Safety Adminis-
tration. The specific grade rating assigned by the tire's
manufacturer in each category is shown on the sidewall
of the tires on your car.
All Passenger Car Tires Must Conform to Federal Safety
Requirements in Addition to These Grades.
Treadwear
The treadwear grade is a comparative rating based on the
wear rate of the tire when tested under controlled con-
ditions on a specified government test course. For ex-
ample, a tire graded 150 would wear one and a half (1
1/2) times as well on the government course as a tire
graded 100. The relative performance of tires depends
upon the actual conditions of their use, however, andmay depart significantly from the norm due to variations
in driving habits, service practices and differences in road
characteristics and climate.
Traction Grades
The traction grades, from highest to lowest, are AA, A, B,
and C. Those grades represent the tire's ability to stop on
wet pavement as measured under controlled conditions
on specified government test surfaces of asphalt and
concrete. A tire marked C may have poor traction perfor-
mance.
WARNING!
The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not
include acceleration, cornering, hydroplaning, or
peak traction characteristics.
