SERVICING CLIMATE CONTROL
The climate control system in your INFINITI is
charged with a refrigerant designed with the envi-
ronment in mind.This refrigerant will not harm the
earth’s ozone layer. However, special charging
equipment and lubricant are required when servic-
ing your INFINITI air conditioner. Using improper
refrigerants or lubricants will cause severe damage
to your climate control system. (See “CAPACITIES
AND RECOMMENDED FUEL/LUBRICANTS” in the “9.
Technical and consumer information” section for
climate control system refrigerant and lubricant
recommendations.)
Your INFINITI retailer will be able to service your
environmentally friendly climate control system.
WARNING
The system contains refrigerant under high pres-
sure. To avoid personal injury, any air condi-
tioner service should be done only by an experi-
enced technician with the proper equipment.
AUDIO OPERATION PRECAUTIONS
Radio
Push the ignition switch to the ACC or ON
position and push the radio band select button
to turn on the radio. If you listen to the radio
with the engine not running, the ignition switch
should be pushed to the ACC position.
Radio reception is affected by station signal
strength, distance from radio transmitter, build-
ings, bridges, mountains and other external
influences. Intermittent changes in reception
quality normally are caused by these external
influences.
Using a cellular phone in or near the vehicle may
influence radio reception quality.
Radio reception :
Your INFINITI radio system is equipped with
state-of-the-art electronic circuits to enhance
radio reception. These circuits are designed to
extend reception range, and to enhance the
quality of that reception.
However there are some general characteristics
of both FM and AM radio signals that can affect
radio reception quality in a moving vehicle,
even when the finest equipment is used. These
characteristics are completely normal in a given reception area, and do not indicate any mal-
function in your INFINITI radio system.
Reception conditions will constantly change
because of vehicle movement. Buildings, ter-
rain, signal distance and interference from
other vehicles can work against ideal reception.
Described below are some of the factors that
can affect your radio reception.
Some cellular phones or other devices may
cause interference or a buzzing noise to come
from the audio system speakers. Storing the
device in a different location may reduce or
eliminate the noise.
