NORMAL OPERATING CONDITION

Description

INFOID:0000000009652084

BASIC OPERATIONS

RELATED TO VOICE RECOGNITION

Related to Telephone

The system should respond correctly to all voice commands without difficulty. If problems are encountered, try
the following solutions.
Where the solutions are listed by number, try each solution in turn, starting with number 1, until the problem is
resolved.

RELATED TO AUDIO

• The majority of the audio malfunctions are the result of outside causes (bad CD/cassette, electromagnetic

interference, etc.). Check the symptoms below to diagnose the malfunction.

• 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, ignition switch turned to each position, and oper-
ation of each piece of electrical equipment, and then determine the cause.

NOTE:
• CD-R is not guaranteed to play because they can contain compressed audio (MP3, WMA) or could be incor-

rectly mastered by the customer on a computer.

• Check if the CDs carry the Compact Disc Logo. If not, the disc is not mastered to the “red book” Compact

Disc Standard and may not play.

Symptom

Possible cause

Possible solution

No image is displayed.

The brightness is at the lowest setting.

Adjust the brightness of the display.

The systems in the video mode.

Press “DISC-AUX” to change the mode. 

The display is turned off.

Press “

 OFF” to turn on the display.

Screen not clear.

Contrast setting is not appropriate.

Adjust the contrast of the display.

The screen is too dim. The move-
ment is slow.

The temperature in the interior of the vehicle is low. 

Wait until the interior of the vehicle has 
warmed up.

Some pixels in the display are dark-
er or brighter than others.

This condition is an inherent characteristic of liquid 
crystal displays.

This is not a malfunction.

Some menu items cannot be se-
lected.

Some menu items become unavailable while the ve-
hicle is driven.

Park the vehicle in a safe location, and 
then operate the multi AV system.

Symptom

Solution

System fails to interpret the com-
mand correctly.

1. Ensure that the command is valid. 

2. Ensure that the command is spoken after the tone.

3. Speak clearly without pausing between words and at level appropriate to the ambient noise lev-
el in the vehicle.

4. Ensure that the ambient noise level is not excessive (for example, windows open or defroster 
on).
NOTE:
If it is too noisy to use the phone, it is likely that the voice commands will not be recognized.

5. If more than one command was said at a time, try saying the commands separately. 

6. If the system consistently fails to recognize commands, the voice training procedure should be 
carried out to improve the recognition response for the speaker. Refer to “Speaker adaptation 
(SA) mode” in “OWNER’S MANUAL”.

The system consistently selects 
the wrong voicetag

1. Ensure that the phone book entry name requested matches what was originally stored. This 
can be confirmed by using the “List Names” command. 

2. Replace one of the names being confused with a new name.
