2014 INFINITI QX50 fuse

4-144Monitor, climate, audio, phone and voice recognition systems
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
The system fails to interpret the command correctly. 1. Ensure that the command format is valid, see “Command List”(P.4-123).
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 voicetag in
the phonebook. 1. Ensure that the voicetag requested matches what was originally stored. (See
“Bluetooth
®Hands-Free Phone
System (models with navigation system)” (P.4-91).)
2. Replace one of the voicetags being confused with a different voicetag.

11. Engine coolant reservoirThe engine cooling system is filled at the
factory with a pre-diluted mixture of 50%
Genuine NISSAN Long Life Antifreeze/Cool-
ant (blue) and 50% water to provide year-
round anti-freeze and coolant protection.
The antifreeze solution contains rust and
corrosion inhibitors. Additional engine
cooling system additives are not neces-
sary.
WARNING
.
Never remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator cool
down. Serious burns could be caused by
high pressure fluid escaping from the
radiator. See precautions in “If your
vehicle overheats” (P.6-10).
. The radiator is equipped with a pressure
type radiator cap. To prevent engine
damage, use only a genuine NISSAN
radiator cap.
