NAVIGATION SYSTEM
5. GPS (GLOBAL POSITIONING SYSTEM)
1. LIMITATIONS OF THE NAVIGATION SYSTEM
The Global Positioning System (GPS)
developed and operated by the U.S. De-
partment of Defense provides an accu-
rate current position, normally using 4
or more satellites, and in some case 3
satellites. The GPS system has a certain
level of inaccuracy. While the naviga-
tion system will compensate for this
most of the time, occasional positioning
errors of up to 100 m (300 feet) can and
should be expected. Generally, position
errors will be corrected within a few
seconds.When the vehicle is receiving signals
from satellites, the “GPS” mark appears
at the top left of the screen.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle
position on the map screen. Tunnels, tall
buildings, trucks, or even the placement
of objects on the instrument panel may
obstruct the GPS signals.
The GPS satellites may not send signals
due to repairs or improvements being
made to them.
Even when the navigation system is re-
ceiving clear GPS signals, the vehicle
position may not be shown accurately or
inappropriate route guidance may occur
in some cases.
This navigation system calculates
the current position using satellite
signals, various vehicle signals, map
data, etc. However, an accurate posi-
tion may not be shown depending on
satellite conditions, road configura-
tion, vehicle condition or other cir-
cumstances.
NOTICE
The installation of window tinting
may obstruct the GPS signals. Most
window tinting contains some metal-
lic content that will interfere with
GPS signal reception of the antenna
in the instrument panel. We advise
against the use of window tinting on
vehicles equipped with navigation
systems.

speech commands are used.
Talk alternately with the other party
on the telephone. If both parties speak
at the same time, the other party may
not hear what has been said. (This is
not a malfunction.)
Keep call volume down. Otherwise,
the other party’s voice may be audible
outside the vehicle and voice echo
may increase. When talking on the
telephone, speak clearly towards the
microphone.
The other party may not hear you
clearly when:
• Driving on an unpaved road. (Mak-
ing excessive traffic noise.)
• Driving at high speeds.
• The roof or windows are open.
• The air conditioning vents are
pointed towards the microphone.
• The sound of the air-conditioning
fan is loud.

are 2 levels of regulations.
Level 1: The file name is in 8.3 format
(8 character file names, with a 3 charac-
ter file extension. File names must be
composed of one-byte capital letters
and numbers. The “_” symbol may also
be included.)
Level 2: The file name can have up to
31 characters (including the separation
mark “.” and file extension). Each
folder must contain fewer than 8 hierar-
chies.

Fan speed is adjusted automatically
according to the temperature setting
and the ambient conditions.
Therefore, the fan may stop for a while
until warm or cool air is ready to flow
immediately after “AUTO” is pressed.
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 wind-
shield effectively.
If “A/C” is switched off, the windows
may fog up more easily.
The windows may fog up if the recircu-
lated air mode is used.When automatic mode is set, the
humidity sensor (see page 319) detects
fog on the windshield and controls the
air conditioning system to prevent fog.
When driving on dusty roads such as
tunnels or in heavy traffic, set the out-
side/recirculated air mode button to the
recirculated air mode. This is effective
in preventing outside air from entering
the vehicle interior. During cooling
operation, setting the recirculated air
mode will also cool the vehicle interior
effectively.
Outside/recirculated air mode may
automatically switch depending on the
temperature setting or the inside tem-
perature.

CAUTION
To prevent the windshield from fog-
ging up
• Do not use the windshield air flow
button during cool air operation in
extremely humid weather. The dif-
ference between the temperature of
the outside air and that of the wind-
shield can cause the outer surface of
the windshield to fog up, blocking
your vision.

In order to prevent the windshield from
fogging up when the outside air is cold,
the following may occur:
• Outside air mode does not switch to
recirculated air mode.
• The dehumidification function oper-
ates.
• The operation cancels after approxi-
mately 1 minute.
In rainy weather, the windows may fog
up. Press the windshield air flow but-
ton.
In extremely humid weather, the win-
dows may fog up.
The pollens are filtered out even if
/ micro dust and pollen filter but-
ton is turned off.
In the following situations, the correct
outside temperature may not be dis-
played, or the display may take longer
than normal to change.
• When stopped, or driving at low
speeds (less than 20 km/h)
• When the outside temperature has
changed suddenly (at the entrance/exit
of a garage, tunnel, etc.)
The dehumidification function may not
operate even when “A/C” is selected.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.
To reduce potential odors from occur-
ring:
• It is recommended that the air condi-
tioning 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
immediately after the air conditioning
system is started in automatic mode.
The air conditioning filter may clog
after long use. The filter may need to be
replaced if the air flow of the air condi-
tioner and heater experiences extreme
reductions in operating efficiency, or if
the windows fog up easily. (For details,
refer to “Owner’s Manual”.)
Settings can be changed. (For details,
refer to “Owner’s Manual”.)

THE CAMERA
The camera for the parking assist
monitor is located as shown in the il-
lustration.
USING THE CAMERA
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.
NOTICE
The parking assist monitor may not
operate properly in the following
cases, or if the precautions described
below are not followed.
• If the back of the vehicle is hit, the
