NOTE:If you experience difficulty in playing a particu-
lar disc, it may be damaged, oversized, or have theft
protection encoding. Try a known good disc before
considering disc player service.
RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the operation of a cellular
phone in your vehicle can cause erratic or noisy perfor-
mance from your radio. This condition may be lessened
or eliminated by relocating the cellular phone antenna.
This condition is not harmful to the radio. If your radio
performance does not satisfactorily “clear” by the repo-
sitioning of the antenna, it is recommended that the radio
volume be turned down or off during cellular phone
operation.
CLIMATE CONTROLS
The controls for the heating and ventilation system in this
vehicle consist of a series of rotary knobs. These comfort
controls can be set to obtain desired interior conditions.

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, and
may 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
