Introduction
This manual explains the operation of the Navigation System. Please read this manual
carefully to ensure proper use. Keep th is manual in your vehicle at all times.
The screen shots in this document and the actual screens of the navigation system dif-
fer depending on whether the functions and/or a contract existed and the map data
available at the time of producing this document.
The Navigation System is one of the most technologically advanced vehicle accesso-
ries ever developed. The system receives satellite signals from the Global Positioning
System (GPS) operated by the U.S. Department of Defense. Using these signals and
other vehicle sensors, the system indicates yo ur present position and assists in locating
a desired destination.
The navigation system is desi gned to select efficient routes from your present starting
location to your destination. The system is al so designed to direct you to a destination
that is unfamiliar to you in an efficient manner. The system uses DENSO maps. The cal-
culated routes may not be the shortest nor the least traffic congested. Your own per-
sonal local knowledge or “short cut” may at times be faster than the calculated routes.
The navigation system’s database includes Point of Interest categories to allow you to
easily select destinations such as restaurants and hotels. If a destination is not in the da-
tabase, you can enter the street address or a major intersection close to it and the sys-
tem will guide you there.
The system will provide both a visual map and audio instructions. The audio instructions
will announce the distance remaining and the direction to turn in when approaching an
intersection. These voice instructions will he lp you keep your eyes on the road and are
timed to provide enough time to allow you to maneuver, change lanes or slow down.
Please be aware that all current vehicle navi gation systems have certain limitations that
may affect their ability to perform properly. The accuracy of the vehicle’s position de-
pends on satellite conditions, road configuration, vehicle condition or other circum-
stances. For more informatio n on the limitations of the system, refer to pages 139
through 141.

zFan speed is adjusted automatically
according to the temperature setting and
the ambient conditions.
z Therefore, the fan may stop for a while until
warm or cool air is ready to flow immedi-
ately after “A U T O ” is pressed.
z The windows will easily fog up when the
humidity in the vehicle is high. Selecting
“A / C ” on will dehumidify the air from the
outlets and defog the windshield effectively.
z If “A / C ” is switched off, the windows may
fog up more easily.
z The windows may fog up if the recirculated
air mode is used. z
When automatic mode is set, the humidity
sensor (see page 305) detects fog on the
windshield and controls the air condition-
ing system to prevent fog.
z When driving on dusty roads such as tun-
nels or in heavy traffic, set the outside/
recirculated air mode button to the recircu-
lated air mode. This is effective in prevent-
ing outside air from entering the vehicle
interior. During cooling operation, setting
the recirculated air mode will also cool the
vehicle interior effectively.
z Outside/recirculated air mode may auto-
matically switch depe nding on the temper-
ature setting or the inside temperature.

FOGGING UP OF THE
WINDOWS
CAUTION
●To prevent the windshield from fogging
up
• Do not use the windshield air flow but- ton during cool air operation in
extremely humid weather. The differ-
ence between the temperature of the
outside air and that of the windshield
can cause the outer surface of the wind-
shield to fog up, blocking your vision.

zThe dehumidification function may not
operate even when “A / C ” is selected.
z During use, various odors from inside and
outside the vehicle may enter into and
accumulate in the air conditioning system.
This may then cause odor to be emitted
from the vents.
z To reduce potential odors from occurring:
• It is recommended that the air condition-
ing system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time imme-
diately after the air conditioning system is
started in automatic mode.
z The air conditioning filter may clog after
long use. The filter may need to be
replaced if the air flow of the air conditioner
and heater experiences extreme reduc-
tions in operating efficiency, or if the win-
dows fog up easily. (For details, refer to
“Owner ’s Manual”.) z
Settings can be changed. (For details, refer
to “Owner’s Manual”.)

NOTICE
●In order to detect fog on the windshield, a
sensor which monitors the temperature
of the windshield, the surround humidity,
etc. is installed. (See page 303.)
Follow these points to avoid damaging
the sensor:
• Do not disassemble the sensor
• Do not spray the glass cleaner on the
sensor or subject it to strong impacts
• Do not stick anything on the sensor
