NOTICE
To ensure correct audio/video system
operations:
Be careful not to spill beverages over
the audio system.
Do not put anything other than a disc
into the slot.
Do not put anything other than an ap-
propriate disc into the DVD player.
The use of a cellular phone inside or
near the vehicle may cause a noise
from the speakers of the audio sys-
tem which you are listening to. How-
ever, this does not indicate a mal-
function.
RADIO RECEPTION
Usually, a problem with radio reception does
not mean there is a problem with your radio —
it is just the normal result of conditions outside
the vehicle.For example, nearby buildings and terrain
can interfere with FM reception. Power lines
or telephone wires can interfere with AM sig-
nals. And of course, radio signals have a lim-
ited range. The farther you are from a station,
the weaker its signal will be. In addition, re-
ception conditions change constantly as your
vehicle moves.
Here are some common reception problems
that probably do not indicate a problem with
your radio:
FM
Fading and drifting stations — Generally, the
effective range of FM is about 40 km (25
miles). Once outside this range, you may no-
tice fading and drifting, which increase with
the distance from the radio transmitter. They
are often accompanied by distortion.
Multi−path — FM signals are reflective, mak-
ing it possible for two signals to reach your an-
tenna at the same time. If this happens, the
signals will cancel each other out, causing a
momentary flutter or loss of reception.
Static and fluttering — These occur when sig-
nals 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 interfere with
those received directly from the radio station,
causing the radio station to sound alternately
strong and weak.
Station interference — When a reflected sig-
nal 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 broadcast.
Static — AM is easily affected by external
sources of electrical noise, such as high ten-
sion power lines, lightening, or electrical mo-
tors. This results in static.

199 (a) Accurate current vehicle position
may not be shown in the following cases:
When driving on a small angled Y−shaped
road.
When driving on a winding road.
When driving on a slippery road such as
in sand, gravel, snow, etc.
When driving on a long straight road.
When freeway and surface streets run in
parallel.
After moving by ferry or vehicle carrier.
When a long route is searched during high
speed driving.
When driving without setting the current
position calibration correctly.
After repeating a change of direction by
going forward and backward, or turning on
a turntable in the parking lot.
When leaving a covered parking lot or
parking garage.
When a roof carrier is installed.
When driving with tire chains installed.
When the tires are worn.
After replacing a tire or tires.
When using tires that are smaller or larger
than the factory specifications.
When the tire pressure in any of the four
tires is not correct.
INFORMATION
If your vehicle cannot receive GPS
signals, you can correct the current
position manually. For information on
setting the current position calibration,
see “
 Current position/tire change
calibration” on page 87.
(b) Inappropriate route guidance may oc-
cur in the following cases:
When turning at an intersection off the
designated route guidance.
If you set more than one destination but
skip any of them, auto reroute will display
a route returning to the destination on the
previous route.
When turning at an intersection for which
there is no route guidance.
When passing through an intersection,
there is no route guidance.
During auto reroute, the route guidance
may not be available for the next turn to
the right or left.
It may take a long time to operate auto re-
route during high speed driving. In auto
reroute, a detour route may be shown.
After auto reroute, the route may not be
changed.
An unnecessary U−turn may be shown or
announced.
A location may have multiple names and
the system will announce one or more.
Some routes may not be searched.
If the route to your destination includes
gravel, unpaved roads or alleys, the route
guidance may not be shown.

200
Your destination point might be shown on
the opposite side of the street.
When a portion of the route has regula-
tions prohibiting the entry of the vehicle
that vary by time or season or other rea-
sons.
The road and map data stored in your nav-
igation system may not be complete or
may not be the latest version.
After replacing the tire, implement the
operation described in the “ Current
position/tire change calibration”. (See
page 87.)
This navigation system uses tire turning data
and is designed to work with factory−speci-
fied tires for your vehicle. Installing tires that
are larger or smaller than the originally
equipped diameter may cause inaccurate
display of the vehicle’s position. The tire pres-
sure also affects the diameter of the tires so
please make sure the tire pressure of all four
tires is correct.
