TROUBLESHOOTING GUIDE
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.
SymptomSolution
System fails to interpret the com-
mand correctly. 1. Ensure that the command is valid. (See ªINFINITI VOICE RECOGNITION SYSTEM (models with navigation system)º
later in this section; page 4-98.)
2. Ensure that the command is spoken after the tone.
3. Speak clearly without pausing between words and at a 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 not be recognized.
5. If more than one command was said at a time, try saying the commands separately.
The system consistently selects the
wrong voicetag. 1. Ensure that the voicetag requested matches what was originally stored. (See ªPHONEBOOK REGISTRATIONº ear-
lier in this section.)
2. Replace one of the names being confused with a new name.

2. Ensure that the command is spoken after the tone.
3. Speak clearly without pausing between words and at a level appropriate to the ambient noise level in the

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 ªSPEAKER ADAPTATION (SA) MODEº earlier in this section.)
The system consistently selects the
wrong voicetag. 1. Ensure that the voicetag requested matches what was originally stored. This can be confirmed by using the ªList
Namesº command. (See ªPHONEBOOKº earlier in this section.)
2. Replace one of the names being confused with a new name.

Symptom/error messageSolution
Displays ªCOMMAND NOT RECOGNIZEDº or the
system fails to interpret the command correctly. 1. Ensure that the command format is valid, see ªCommand Listº earlier in this section.
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 the command should be tried with these
in place.
The system consistently selects the wrong voic-
etag in the phonebook. 1. Ensure that the voicetag requested matches what was originally stored. (See ªBLUETOOTH
THANDS-
FREE PHONE SYSTEM WITH NAVIGATION SYSTEMº earlier in this section; page 4-74.)
2. Replace one of the voicetags being confused with a different voicetag.

Some vehicles are equipped with engine com-
partment and passenger compartment fuse
boxes that use only type
sAfuses. Other ve-
hicles are equipped with type
sAfuses in the
engine compartment fuse box and type
sB
fuses in the passenger compartment fuse box.
Type
sAfuses are provided as spare fuses. They
are stored in the passenger compartment fuse
box.
Type
sAfuses can be installed in the engine
compartment and passenger compartment fuse
boxes. If a type
sAfuse is used to replace a typesB
fuse, the typesAfuse will not be level with the
fuse pocket as shown in the illustration. This
will not affect the performance of the fuse.
Make sure the fuse is installed in the fuse box
securely.
Type
sBfuses cannot be installed in the under-
hood fuse boxes. Only use type
sAfuses in the
underhood fuse boxes.
ENGINE COMPARTMENT
CAUTION
Never use a fuse of a higher or lower amperage
rating than that specified on the fuse box cover.
This could damage the electrical system or
cause a fire.
If any electrical equipment does not operate,
check for an open fuse.
1. Be sure the ignition switch is pushed to the LOCK position and the headlight
switch is turned off.

2. Open the engine hood and remove thecover on the battery and the fuse/fusible
link holder.
3. Remove the fuse/fusible link holder cover.
4. Remove the fuse with the fuse puller.
5. If the fuse is open
sA, replace it with a
new fuse
sB. Spare fuses are stored in the
passenger compartment fuse box.
6. If a new fuse also opens, have the elec- trical system checked and repaired by an
INFINITI retailer.
Fusible links
If any electrical equipment does not operate
and fuses are in good condition, check the
fusible links. If any of these fusible links are
melted, replace only with genuine INFINITI
parts.
