RADIO FREQUENCIES
AM and FM frequencies are established by the Federal Communications
Commission (FCC) and the Canadian Radio and Telecommunications
Commission (CRTC). Those frequencies are:
AM - 530, 540–1700, 1710 kHz
FM- 87.7, 87.9–107.7, 107.9 MHz
RADIO RECEPTION FACTORS
There are three factors that can affect radio reception:
•Distance/strength: The further you travel from an FM station, the
weaker the signal and the weaker the reception.
•Terrain: Hills, mountains, tall buildings, power lines, electric fences,
traffic lights and thunderstorms can interfere with your reception.
•Station overload: When you pass a broadcast tower, a stronger signal
may overtake a weaker one and play while the weak station frequency
is displayed.
CASSETTE/PLAYER CARE
Do:
•Use only cassettes that are 90 minutes long or less.

HOMELINKWIRELESS CONTROL SYSTEM (IF EQUIPPED)
The HomeLinkWireless Control System, located on the overhead
console, provides a convenient way to replace up to three hand-held
transmitters with a single built-in device. This feature will learn the radio
frequency codes of most current transmitters to operate garage doors,
entry gate operators, security systems, entry door locks, and home or
office lighting.
When programming your HomeLinkWireless Control System to
a garage door or gate, be sure that people and objects are out of
the way to prevent potential harm or damage.
Do not use the HomeLinkWireless Control System with any garage
door opener that lacks safety stop and reverse features as required by
U.S. federal safety standards (this includes any garage door opener
model manufactured before April 1, 1982). A garage door which cannot
detect an object, signaling the door to stop and reverse, does not meet
current U.S. federal safety standards. For more information, contact
HomeLinkat:www.homelink.comor1–800–355–3515.
Retain the original transmitter for use in other vehicles as well as for
future programming procedures (i.e. new HomeLinkequipped vehicle
purchase). It is also suggested that upon the sale of the vehicle, the
programmed Homelinkbuttons be erased for security purposes, refer to
Programmingin this section.
Programming
Do not program HomeLinkwith the vehicle parked in the garage.
Note:Some vehicles may require the ignition switch to be turned to the
second (or“ACC”) position for programming and/or operation of the
HomeLink. It is also recommended that a new battery be placed in the
hand-held transmitter of the device being programmed to HomeLinkfor
quicker training and accurate transmission of the radio-frequency signal.

CELL PHONE USE
The use of Mobile Communications Equipment has become increasingly

equipment to avoid negating these benefits.
Mobile Communication Equipment includes, but is not limited to cellular
phones, pagers, portable email devices, in vehicle communications
systems, telematics devices and portable two-way radios.
A driver’s first responsibility is the safe operation of the vehicle.
