ception (e.g. a place with clear view 
and no obstacles generating external 
noises).

Buzz/rattle sound from speaker

The majority of buzz/rattle sounds are 
not indicative of an issue with the speak-
er, usually something nearby the speak-
er is causing the buzz/rattle.

Description

INFOID:0000000010122572

RELATED TO NOISE

The majority of the audio concerns are the result of outside causes (bad CD, electromagnetic interference,

etc.).

The following noise results from variations in field strength, such as fading noise and multi-path noise, or

external noise from trains and other sources. It is not a malfunction.

• Fading noise: This noise occurs because of variations in the field strength in a narrow range due to moun-

tains or buildings blocking the signal.

• Multi-path noise: This noise results from the waves sent directly from the broadcast station arriving at the

antenna at a different time from the waves which reflect off mountains or buildings.

The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning.

Check if noise is caused and/or changed by engine speed, power switch turned to each position, and opera-

tion of each piece of electrical equipment, and determine the cause.

NOTE:

The source of the noise can be found easily by listening to the noise while removing the fuses of electrical

components, one by one.

Type of Noise and Possible Cause

RELATED TO HANDS-FREE PHONE

Occurrence condition

Possible cause

Occurs only when engine is ON.

A continuous growling noise occurs. The speed of 
the noise varies with changes in the engine speed.

• Power components

The occurrence of the noise is linked with the operation of the fuel pump.

• Fuel pump condenser

Noise only occurs when various 
electrical components are oper-
ating.

A cracking or snapping sound occurs with the op-
eration of various switches.

• Relay malfunction, AV control unit malfunc-

tion

The noise occurs when various motors are operat-
ing.

• Motor case ground
• Motor

The noise occurs constantly, not just under certain conditions.

• Rear defogger coil malfunction
• Open circuit in printed heater
• Poor ground of antenna feeder line

A cracking or snapping sound occurs while the vehicle is being driven, especially when 
it is vibrating excessively.

• Ground wire of body parts
• Ground due to improper part installation
• Wiring connections or a short circuit

Symptom

Cause and Counter measure

Does not recognize cellular phone connection (No connection is 
displayed on the display at the guide).

Some Bluetooth

®

 enabled cellular phones may not be recognized 

by the in-vehicle phone module.
Refer to “RELATED TO HANDS-FREE PHONE (Check Compati-
bility)” in 

AV-306, "Symptom Table"

.

Cannot use hands-free phone.

Customer will not be able to use a hands-free phone under the fol-
lowing conditions:
• The vehicle is outside of the telephone service area.
• The vehicle is in an area where it is difficult to receive radio 

waves; such as in a tunnel, in an underground parking garage, 
near a tall building or in a mountainous area.

• The cellular phone is locked to prevent it from being dialed.
NOTE:
While a cellular phone is connected through the Bluetooth

®

 wire-

less connection, the battery power of the cellular phone may dis-
charge quicker than usual. The Bluetooth

®

 Hands-Free Phone 

System cannot charge cellular phones.

NORMAL OPERATING CONDITION

RELATED TO NAVIGATION

Basic Operation

Vehicle Mark

The other party’s voice cannot be heard by hands-free phone.

When the radio wave condition is not ideal or ambient sound is too 
loud, it may be difficult to hear the other person’s voice during a 
call.

Poor sound quality.

Do not place the cellular phone in an area surrounded by metal or 
far away from the in-vehicle phone module to prevent tone quality 
degradation and wireless connection disruption.

Symptom

Cause

Remedy

Map screen and BIRDVIEW™ 
Name of the place vary with the 
screen.

Some thinning of the character data is done to pre-
vent the display becoming to complex. In some 
cases and in some locations, the display contents 
may differ.
The same place name, street name, etc. may not 
be displayed every time on account of the data 
processing.

System is not malfunctioning.

Vehicle mark is not positioned cor-
rectly.

Vehicle is transferred by ferry or by towing after its 
power switch is turned to OFF.

Drive the vehicle for a while in the GPS sat-
ellite signal receiving condition.

Screen will not switch to nighttime 
mode after the lighting switch is 
turned ON.

The daytime screen is selected by the “SWITCH 
SCREENS” when the last time the screen dim-
ming setting is done.
Switching between daytime/nighttime screen may 
be inhibited by the automatic illumination adjust-
ment function.

Perform screen dimming and select the 
nighttime screen by “SWITCH SCREENS”.

Map screen will not scroll in accor-
dance with the vehicle travel.

Current location is not displayed.

Press “MAP” button to display the current lo-
cation.

Press “MAP” button to display the current lo-
cation.

Accuracy indicator (GPS satellite 
mark) on the map screen stays 
gray.

GPS satellite signal is intercepted because the ve-
hicle is in or behind a building.

Move the vehicle out to an open space.

GPS satellite signal cannot be received because 
an obstacle is placed on top of the instrument pan-
el.

Do not place anything on top of the meter dis-
play (instrument panel).

GPS satellites are not visible from current location. Wait until GPS satellites are visible by mov-

ing the vehicle.
