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” earlier in this section; page 4-96.)
2. Replace one of the voicetags being confused with a different voicetag.

8-6Maintenance and do-it-yourself

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 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.
BRAKE BOOSTER
Check the brake booster function as follows:
1. With the engine off, depress and release the foot brake pedal more than 20 times.
When the foot brake pedal movement
(distance of travel) remains the same from
one pedal application to the next, con-
tinue on to the next step.
2. While depressing the foot brake pedal, start the engine.
3. With the foot brake pedal depressed, stop the engine. Keep the pedal depressed for
about 30 seconds. 4. Run the engine for 1 minute without de-
pressing the foot brake pedal, then turn it
off. Depress the foot brake pedal several
times. The pedal travel distance will de-
crease gradually with each depression as
the hydraulic pressure decreases.
If the brakes do not operate properly, have the
brakes checked by an INFINITI retailer.

FUSES
Maintenance and do-it-yourself8-21

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.
3. Remove the fuse/fusible link holder cover
1,2or3.
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.
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.

8-22Maintenance and do-it-yourself

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 so
equipped)
To reduce battery drain, the extended storage
switch comes from the factory switched off.
Prior to delivery of your vehicle, the switch is
pushed in (switched on) and should always
remain on.
If any electrical equipment does not operate,
remove the extended storage switch and check
for an open fuse.
SDI2519SDI2704
Maintenance and do-it-yourself8-23

NOTE:
If the extended storage switch malfunctions or if
the fuse is open, it is not necessary to replace
the switch. In this case, remove the extended
storage switch and replace it with a new fuse of
the same rating.
How to remove the extended storage switch:
1. To remove the extended storage switch,be sure the ignition switch is in the OFF or
LOCK position.
2. Be sure the headlight switch is in the OFF position.
3. Remove the fuse box cover.
4. Pinch the locking tabs
1found on each
side of the storage switch.
5. Pull the storage switch straight out from the fuse box
2.
Replace the battery as follows:
1. Release the lock knob at the back of the
Intelligent Key and remove the mechanical
key. 2. Insert a small screwdriver into the slit of
the corner and twist it to separate the
upper part from the lower part. Use a
cloth to protect the casing.
3. Replace the battery with a new one.
Recommended battery: CR2025 or equiva-
lent.
● Do not touch the internal circuit and
electric terminals as it could cause a
malfunction.
● Hold the battery by the edges. Holding
the battery across the contact points will
seriously deplete the storage capacity.
● Make sure that the + side faces the
bottom of the case.
