TROUBLESHOOTING GUIDE
The system should respond correctly to all voice
commands without difficulty. If problems are en-
countered, 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 command correctly. 1. Ensure that the command is valid. See “List of voice commands” in this section.
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.
6. If the system consistently fails to recognize commands, the voice training procedure should be carried out to im-
prove the recognition response for the speaker. See “Speaker Adaptation (SA) mode” in this section.
The system consistently selects the wrong entry from the
phone book. 1. Ensure that the phone book entry name requested matches what was originally stored. This can be confirmed by
using the “List Names” command. See “Phone book” 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 en-
countered, 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 RECOG-
NIZED” or the system fails to interpret
the command correctly. 1. Ensure that the command format is valid, see “Standard Mode command list” or “Alternate Command Mode command list” earlier in this
section.
2. Speak clearly using your normal speech pattern 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.
The system consistently selects the
wrong voicetag in the phonebook. 1. Ensure that the voicetag requested matches what was originally stored. See “Bluetooth
Hands-Free Phone System with Navigation
System” in this section.
2. Replace one of the voicetags being confused with a different voicetag.

If the brakes do not operate properly, have the
brakes checked by a NISSAN dealer.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front and rear disc-type brakes self-adjust
every time the brake pedal is applied.
WARNING
See a NISSAN dealer for a brake system
check if the brake pedal height does not
return to normal.
Brake pad wear indicators
The disc brake pads on your vehicle have audible
wear indicators. When a brake pad requires re-
placement, a high pitched scraping or screech-
ing sound will be heard when the vehicle is in
motion. The noise will be heard whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear indicator
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 to
moderate stops is normal and does not affect the
function or performance of the brake system.Proper brake inspection intervals should
be followed.
For more information regarding
brake inspections, see the appropriate mainte-
nance schedule information in the “NISSAN Ser-
vice and Maintenance Guide”.
Two types of fuses are used. Type
Ais used in
the fuse boxes in the engine compartment. Type
Bis used in the passenger compartment fuse
box.
Type A fuses are provided as spare fuses. They
are stored in the passenger compartment fuse
box.
Type A fuses can be installed in the engine com-
partment and passenger compartment fuse
boxes.

Page 413 of 474
If a type A fuse is used to replace a type B fuse,
the type A fuse 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 B fuses cannot be installed in the under-
hood fuse boxes. Only use type A fuses in the
underhood fuse boxes.ENGINE COMPARTMENT
CAUTION
Never use a fuse of a higher or lower
amperage rating than specified on the
fuse box cover. This could damage the
electrical system or cause a fire.
If any electrical equipment does not come on,
check for an open fuse. 1. Be sure the ignition switch and the headlight switch are OFF.
2. Open the engine hood. 3. Remove the fuse box cover by pushing the
tab and lifting the cover up.
4. Remove the fuse with the fuse puller. The fuse puller is located in the center of the fuse
block in the passenger compartment.

5. If the fuse is openA, replace it with a new
fuse
B.
6. If a new fuse also opens, have the electrical system checked and repaired by a NISSAN
dealer.
Fusible links
If the electrical equipment does not operate and
fuses are in good condition, check the fusible
links. If any of these fusible links are melted,
replace with only Genuine NISSAN parts.
PASSENGER COMPARTMENT
CAUTION
Never use a fuse of a higher or lower
amperage rating than 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 and the headlight switch are OFF.
2. Pull the fuse box cover to remove.
3. Remove the fuse with the fuse puller. 4. If the fuse is open
A, replace it with an
equivalent good fuse
B.
5. Push the fuse box cover to install.
6. If a new fuse also opens, have the electrical system checked and repaired by a NISSAN
dealer.
