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 “INFINITI VOICE RECOGNITION SYSTEM (models with navigation system)”
later in this section; page 4-109.)
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 “VEHICLE PHONEBOOK” earlier in
this section.)
2. Replace one of the names being confused with a new name.

TROUBLESHOOTING GUIDE
The system should respond correctly to all voice commands without difficulty. If problems are encountered, follow the solutions given in this guide for
the appropriate error.
Where the solutions are listed by number, try each solution in turn, starting with number one, until the problem is resolved.
Symptom/error messageSolution
Displays “COMMAND NOT RECOGNIZED” or the
system fails to interpret the command correctly. 1. Ensure that the command format is valid, see “Command List” 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 “BLUETOOTH
HANDS-
FREE PHONE SYSTEM (models with navigation system)” earlier in this section; page 4-86.)
2. Replace one of the voicetags being confused with a different voicetag.

If the brakes do not operate properly, have the
brakes checked by an INFINITI retailer.
SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjusting
brakes.
The disc-type brakes self-adjust every time the
brake pedal is applied.
WARNING
See an INFINITI retailer for a brake system
check if the brake pedal height does not return
to normal.
BRAKE PAD WEAR WARNING
The disc brake pads have audible wear warn-
ings. When a brake pad requires replacement, it
will make a high pitched scraping sound when
the vehicle is in motion. This scraping sound
will first occur only when the brake pedal is
depressed. After more wear of the brake pad,
the sound will always be heard even if the brake
pedal is not depressed. Have the brakes
checked as soon as possible if the wear warn-
ing sound is heard.
Under some driving or climate conditions, occa-
sional brake squeak, squeal or other noise may
be heard. Occasional brake noise during light tomoderate stops is normal and does not affect
the function or performance of the brake sys-
tem.
Proper brake inspection intervals should be fol-
lowed.
For additional information, see the main-
tenance log section of your “INFINITI Service
and Maintenance Guide” for maintenance inter-
vals.

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 OFF or LOCK position and the head-
light switch is turned to OFF.
2. Open the engine hood and remove the cover 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
A, replace it with a
new fuse
B. 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.
The holder1also contains the fuses. For
checking and/or replacing, see an INFINITI re-
tailer.
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.

PASSENGER 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 OFF or LOCK position and the head-
light switch is turned to OFF.
2. Open the fuse box lid. 3. Remove the fuse with the fuse puller
A.
4. If the fuse is open, replace it with a new fuse.
5. If a new fuse also opens, have the electri- cal system checked and repaired by an
INFINITI retailer. Spare fuses are stored in
the fuse box.
Extended storage switch (if equipped)
If any electrical equipment does not operate,
remove the extended storage switch and check
for an open issue.
NOTE:
The extended storage switch is used for long
term vehicle storage. Even if the extended stor-
age switch is broken it is not necessary to re-
place it. Replace only the open fuse in the switch
with a new fuse.
