To adjust the Zone setting:
1. Determine the desired Zone Number
based upon your current location on
the Zone Map.
2. Press and hold the button for 6 sec-
onds, the current Zone Number will
appear on the display.
3. Pressing and holding the button
again will cause the numbers to incre-
ment (Note: they will repeat …13, 14,
15, 1, 2, …). Releasing the button
when the desired Zone Number
appears on the display will set the new
Zone.
4. Within about 5 seconds the compass
will start displaying a compass head-
ing again.
There are some conditions that can
cause changes to the vehicle magnets,
such as installing a ski rack or a CB
antenna. Body repair work on the vehicle
can also cause changes to the vehicle's
magnetic field. In these situations, the
compass will need to be re-calibrated to
quickly correct for these changes. To re-
calibrate the compass:1. Press and hold the button for more
than 9 seconds. When the compass
memory is cleared a "C" will appear in
the display.
2. To calibrate the compass, drive the
vehicle in 2 complete circles at less
than 5 mph (8 km/h).
Integrated HomeLink
®Wireless Control
System
The HomeLink
®Wireless Control System
provides a convenient way to replace up
to three hand-held radio-frequency (RF)
transmitters with a single built-in device.
This innovative feature will learn the
radio frequency codes of most current
transmitters to operate devices such as
gate operators, garage door openers,
entry door locks, security systems, even
home lighting. Both standard and rolling
code-equipped transmitters can be pro-
grammed by following the outlined proce-
dures. Additional HomeLink
®information
can be found at: www.homelink.com or
by calling 1-800-355-3515.Retain the original transmitter of the RF
device you are programming for use in
other vehicles as well as for future
HomeLink
®programming. It is also sug-
gested that upon the sale of the vehicle,
the programmed HomeLink
®buttons be
erased for security purposes.
WARNING
Before programming HomeLink®to
a garage door opener or gate oper-
ator, make sure that people and
objects are out of the way of the
device to prevent potential harm or
damage. Do not use HomeLink
®
with any garage door opener that
lacks the safety stop and reverse
features required by U.S. federal
safety standards (this includes any
garage door opener model manu-
factured before April 1, 1982). A
garage door that cannot detect an
object - signaling the door to stop
and reverse - does not meet current
U.S. federal safety standards. Using
a garage door opener without these
features increases the risk of seri-
ous injury or death.

Antenna
Glass antenna (if equipped)
When the radio power switch is turned on
while the engine start/stop button is in
either the “ON” or “ACC” position, your
car will receive both AM and FM broad-
cast signals through the antenna in the
rear window glass.

CAUTION
• Do not clean the inside of the rear
window glass with a cleaner or
scraper to remove foreign
deposits as this may cause dam-
age to the antenna elements.
Avoid adding metallic coatings
such as Ni, Cd, and so on. These
can disturb receiving AM and FM
broadcast signals.

How vehicle audio works
AM and FM radio signals are broadcast
from transmitter towers located around
your city. They are intercepted by the
radio antenna on your vehicle. This signal
is then received by the radio and sent to
your vehicle speakers.
When a strong radio signal has reached
your vehicle, the precise engineering of
your audio system ensures the best pos-
sible quality reproduction. However, in
some cases the signal coming to your
vehicle may not be strong and clear. This
can be due to factors, such as the dis-
tance from the radio station, closeness of
other strong radio stations or the pres-
ence of buildings, bridges or other large
obstructions in the area.AM broadcasts can be received at
greater distances than FM broadcasts.
This is because AM radio waves are
transmitted at low frequencies. These
long, low frequency radio waves can fol-
low the curvature of the earth rather than
travelling straight out into the atmos-
phere. In addition, they curve around
obstructions so that they can provide bet-
ter signal coverage.FM broadcasts are transmitted at high
frequencies and do not bend to follow the
earth's surface. Because of this, FM
broadcasts generally begin to fade at
short distances from the station. Also,
FM signals are easily affected by build-
ings, mountains, or other obstructions.
These can result in certain listening con-
ditions which might lead you to believe a
problem exists with your radio. The fol-
lowing conditions are normal and do not
indicate radio trouble:

Fading - As your vehicle moves away
from the radio station, the signal will
weaken and sound will begin to fade.
When this occurs, we suggest that you
select another stronger station.
Flutter/Static - Weak FM signals or
large obstructions between the trans-
mitter and your radio can disturb the
signal causing static or fluttering nois-
es to occur. Reducing the treble level
may lessen this effect until the distur-
bance clears. Station Swapping - As a FM signal
weakens, another more powerful sig-
nal near the same frequency may
begin to play. This is because your
radio is designed to lock onto the clear-
est signal. If this occurs, select another
station with a stronger signal.
Multi-Path Cancellation - Radio signals
being received from several directions
can cause distortion or fluttering. This
can be caused by a direct and reflect-
ed signal from the same station, or by
signals from two stations with close
frequencies. If this occurs, select
another station until the condition has
passed.
Using a cellular phone or a two-way
radio
When a cellular phone is used inside the
vehicle, noise may be produced from the
audio system. This does not mean that
something is wrong with the audio equip-
ment. In such a case, use the cellular
phone at a place as far as possible from
the audio equipment.

CAUTION
When using a communication sys-
tem such as a cellular phone or a
radio set inside the vehicle, a sepa-
rate external antenna must be fitted.
When a cellular phone or a radio set
is used with an internal antenna
alone, it may interfere with the vehi-
cle's electrical system and adverse-
ly affect safe operation of the vehi-
cle.
WARNING
Do not use a cellular phone while
driving. Stop at a safe location to
use a cellular phone.
