NOTICE
To ensure correct audio/video sys-
tem operations:
DBe careful not to spill beverages
over the audio/video system.
DDo not put anything other than an
appropriate discs into the CD
changer or DVD changer.
DThe use of a cellular phone inside
or near the vehicle may cause a
noise from the speakers of the au-
dio/video system which you are lis-
tening to. However, this does not
indicate a malfunction.
DRadio reception
Usually, a problem with radio reception
does not mean there is a problem with your
radio — it is just the normal result of condi-
tions outside the vehicle.
For example, nearby buildings and terrain
can interfere with FM reception. Power
lines or telephone wires can interfere with
AM signals. And of course, radio signals
have a limited range. The farther you are
from a station, the weaker its signal will be.
In addition, reception conditions change
constantly as your vehicle moves.
Here are some common reception prob-
lems that probably do not indicate a prob-
lem with your radio:
FM
Fading and drifting stations — Generally,
the effective range of FM is about 25 miles
(40 km). Once outside this range, you may
notice fading and drifting, which increase
with the distance from the radio transmit-
ter. They are often accompanied by distor-
tion. Multi−
path — FM signals are reflective,
making it possible for two signals to reach
your antenna at the same time. If this hap-
pens, the signals will cancel each other
out, causing a momentary flutter or loss of
reception.
Static and fluttering — These occur when
signals are blocked by buildings, trees, or
other large objects. Increasing the bass
level may reduce static and fluttering.
Station swapping — If the FM signal you
are listening to is interrupted or weakened,
and there is another strong station nearby
on the FM band, your radio may tune in the
second station until the original signal can
be picked up again.
AM
Fading — AM broadcasts are reflected by
the upper atmosphere — especially at
night. These reflected signals can inter-
fere with those received directly from the
radio station, causing the radio station to
sound alternately strong and weak.
Station interference — When a reflected
signal and a signal received directly from
a radio station are very nearly the same
frequency, they can interfere with each
other, making it difficult to hear the broad-
cast.
Static — AM is easily affected by external
sources of electrical noise, such as high
tension power lines, lightening, or electri-
cal motors. This results in static.
XM r
Cargo loaded on the roof luggage carrier,
especially metal objects, may adversely
affect the reception of XM rSatellite Radio.
Alternation or modifications carried out
without appropriate authorization may in-
validate the user ’s right to operate the
equipment.

pens, wipe it off as soon as pos-
sible.
DIf the tire size is changed, the area
displayed on the screen may
change.
DWhen washing the vehicle, do not
apply intensive bursts of water to
the camera or camera area. Doing
so may result in the camera mal-
functioning.
INFORMATION
If the camera lens becomes dirty, it
cannot transmit a clear image. If wa-
ter droplets, snow, or mud adhere to
the lens, rinse with water and wipe
with a soft cloth. If the lens is ex-
tremely dirty, wash it with a mild
cleanser and rinse.
DArea displayed on screen
Image is displayed approximately level
on screen.
Corners of bumper
The area detected by the camera is limi-
ted. The camera does not detect objects
which are close to either corner of the
