BASIC OPERATIONS

NOTE:
Locations stored in the Address Book and other memory functions may be lost if the vehicle's battery is dis-
connected or becomes discharged. If this occurs, service the vehicle's battery as necessary and re-enter the
information in the Address Book. 

RELATED TO VOICE RECOGNITION

Related to basic operation

Related to item choice

The system should respond correctly to all voice commands without difficulty. If problems are encountered, fol-
low the solutions given in this guide for the appropriate error.
Where the solutions are listed b number, try each solution in turn, starting with number one, until the problem
is resolved.

Symptom

Possible cause

Possible solution

No image is displayed.

The brightness is at the lowest setting.

Adjust the volume of voice guidance.

Voice guidance is not provided for certain streets 
(roads displayed in gray).

This is not a malfunction.

No map is displayed on the 
screen.

A screen other than map screen is displayed.

Push <MAP>.

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 
darker 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 
vehicle is driven.

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

Symptom

Possible cause

Possible solution

The system does not 
recognize your com-
mand.
or
The system recognizes 
your command incor-
rectly

The interior of the vehicle is too noisy.

Close the windows or have other occupants qui-
et.

ready

Push and release “

” switch on the steering 

switch, and speak a command after the tone 
sounds

8 seconds or more have passed after you pushed and 

released “

” switch on the steering switch.

Make sure to speak a command within 8 sec-

onds after you push and release “

” switch on 

the steering switch. 

Only a limited range od voice commands is usable for 
each screen.

Use a correct voice command appropriate for the 
current screen

The second of the fan od the air conditioner is too loud.

If the air conditioner is set to “Auto”, the fan 
speed is automatically lowered and voice com-
mands can be recognized more easily.

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
resolves.

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/ error message

Solution

Displays “COMMAND NOT REC-
OGNIZED” or the system fails to 
interpret the command correctly.

1. Ensure that the command format is valid.

2. Speak clearly without pausing between words and at a level appropriate to the ambient noise 
level.

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

4. If optional words of the command have been omitted, then command should be tried with 
these in place.

The system consistently selects 
the wrong voicetag

1.Ensure that the voicetag requested matches what was originally stored. This can be confirmed 
by giving the Addressbook Directory or Phone Directory command.

2. Replace one of the voicetags being confused with a different voicetag.

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 
level 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 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. See “Speaker adaptation 
(SA) mode” earlier in this section. Refer to “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.
