navigation INFINITI QX4 2001 Factory Workshop Manual

IThe enlarged intersection map may display an ªUnknown Streetº message at some street intersections.
IBecause of road configuration, etc. the guide may finish early. If this occurs, follow the marker to reach
your destination.
IDestination area side information (left side and right side) may differ from actual conditions because of
data error.
Unable to Set Destination, Way Point, and/or Menu ItemsNBEL0235S0301
Symptom Possible cause Repair order
Unable to search way points in
re-search modeA way point already crossed or determined to
have been crossed.If you desire to pass through a way point for a
second time, reperform route edit.
Turn list is not displayed.Route search does not occur.Set designation areas and perform route
search.
Car marker does not appear on recom-
mended route.Drive on the recommended route.
Route guide is canceled.Turn the route guide ON. (Push ªVOICEº
switch.)
Automatic search does not func-
tion.Vehicle is not running on search object route
(road indicated by orange, brown or red line).Drive the vehicle on the search object route
or perform a manual route search. Note that
all routes will be re-searched at this time.
Unable to select detour route. Vehicle is not running on recommended route.Use the ªRE-ROUTEº mode to search again
or return to the recommended route.
Detour route search results are
identical to previous search.All possible conditions were considered, but
results are the same.This is not abnormal.
Unable to set a way point.More than five way points have been previ-
ously set (and not cleared).More than five way points cannot be specified
at the same time. Break down into smaller
segments and perform search.
Unable to select starting point
during route edit.Starting point will normally be your present
location during route edit.This is not abnormal.
Cannot select certain menu items. While vehicle is running.Park the vehicle in a safe area and perform
operation.
Voice Guide InformationNBEL0235S0302
Symptom Possible cause Repair order
Voice guide does not function. Voice guide is only available at certain inter-
sections (marked with
). In some cases, the
guide is not available even when the vehicle
makes a turn.This is not abnormal.
Vehicle is not running on recommended route.Return to recommended route or reperform
route search.
Voice guide is OFF. Set voice guide to the ON position.
Route guide is canceled.Turn the route guide ON. (Push ªVOICEº
switch.)
The guide content does not corre-
spond to actual conditions.The content of the voice guide may vary
depending on the type of junction.Operate vehicle following the traffic rules and
regulation.
Route Search InformationNBEL0235S0303
Symptom Possible cause Repair order
Proceeding in desired direction.
However, route search in desired
direction does not function.Unable to find appropriate route in the desired
direction.This is not abnormal.
NAVIGATION SYSTEM
This Condition is Not Abnormal (Cont'd)
EL-430

Symptom Possible cause Repair order
No route is displayed.No object route is searched near destination
area.Adjust position to wide road (brown) near des-
tination area. In an area where traffic direction
is displayed separately, pay close attention to
the direction of travel. Set the destination area
and the way point over the road.
Starting point and destination areas are very
near.Move destination areas away from starting
point on the screen.
Recommended route which has
been passed disappears from the
display.The recommended route is divided into indi-
vidual control segments. When way point 1 is
passed, the data from the starting point to the
way point 1 is erased.This is not abnormal.
Search recommends roundabout
route.There may be special conditions for roads
near the starting point and destination area
(one-way traffic, etc.). A roundabout route may
be displayed.Slightly change starting point and destination
area settings.
Landmark display does not show
actual conditions.Mistaken or missing map data may result in
erroneous display.Change map CD.
Recommended route drawn
slightly away from starting point,
way points, and destination area.Course search data may not exist for closely
positioned starting point, way points, and des-
tination area shown on the map. Route guide
starting point, way point, and destination point
may be separated.Set the destination area to the general route
(indicated by a thick brown line). However,
even if the selected route is a major one,
appropriate route search data may not be
available.
LOCATION OF CAR MARKERNBEL0235S04IIf the vehicle has been parked in a multi-level parking facility or underground parking facility, the car marker
position may be inaccurate immediately after exiting the parking facility.
IThe GPS accuracy is within±100 m (300 ft). Even when receiving conditions are excellent, further posi-
tional correction may not occur.
STREET INDICATIONNBEL0235S05IStreet names displayed on the map may differ from the actual street names.
IAn ªUnknown Streetº message may appear on the map in place of street name information.
RESEARCHNBEL0235S06IPosition may be searched by house number. However, the displayed position and street may differ from
the actual position and street.
IWhen position is searched using POI, the displayed position may differ from the actual position.
ISome data may not be available for new buildings and other structures in a map.
GPS ANTENNANBEL0235S07IDo not place metal objects above the GPS antenna mounted on the rear parcel shelf. This will cause
interference with signal reception.
IDo not place mobile telephones or vehicle radio transceivers in close proximity to the GPS antenna
mounted on the rear parcel shelf. This may cause interference with signal reception.

InitializationNBEL0237This procedure is for initializing the current location. Perform ªIni-
tialize Locationº when the vehicle is transported a long distance by
trailer, etc.
Map with grey background appears and the vehicle location can-
not be adjusted by scrolling the display when the vehicle location
in the memory is out of the area of the inserted map data.
Perform ªInitialize Locationº when this occurs.
NOTE:
IOnly initialize the system when the display & NAVI control
unit is replaced. If the system is initialized in other cases,
it may cause inaccurate positioning of the position marker
for a while.
IInitialize the system outside for receiving the radio wave
from the GPS satellite.

HOW TO PERFORMNBEL0237S011. Switch the navigation system mode to self-diagnosis by push-
ing both ªMAPº and ªD/Nº switches at the same time for more
than 5 seconds.

to 15 minutes.)
NOTE:
Drive the vehicle for a while* in order to change the receiving
condition of the radio wave from the GPS satellite if the GPS
icon does not turn green.
* The driving distance which is necessary depends on the
receiving condition of the radio wave from the GPS satellite.

DISPLAY SCREENNBHA0016S01Displays the operational status of the system.
AUTO SWITCHNBHA0016S02The compressor, intake doors, air mix door, outlet doors, and blower speed are automatically controlled so
that the in-vehicle temperature will reach, and be maintained at the set temperature selected by the operator.
ECON SWITCHNBHA0016S03By pressing the ECON switch, the display should indicate ECON and the compressor always turns OFF. With
the compressor OFF, the system will not remove heat (cool) or de-humidify. The system will maintain the in-
vehicle temperature at the set temperature when the set temperature is above the ambient (outside) tempera-
ture. The system will set the intake doors to the outside air position.
TEMPERATURE SWITCH (POTENTIO TEMPERATURE CONTROL) WITHOUT NAVIGATION
SYSTEM
NBHA0016S04Increases or decreases the set temperature.
OFF SWITCHNBHA0016S05The compressor and blower are OFF, the intake doors are set to the outside air position, and the air outlet
doors are set to the foot (80% foot and 20% defrost) position.
FAN SWITCHNBHA0016S06Manually controls the blower speed. Four speeds are available for manual control (as shown on the display
screen):
low
, medium low, medium high, high
RECIRCULATION (REC) SWITCHNBHA0016S07OFF position: Outside air is drawn into the passenger compartment.
ON position: Interior air is recirculated inside the vehicle.
DEFROSTER (DEF) SWITCHNBHA0016S08Positions the air outlet doors to the defrost position. Also positions the intake doors to the outside air position.
MODE SWITCHNBHA0016S09Controls the air discharge outlets.
TEMPERATURE DIAL (POTENTIO TEMPERATURE CONTROL) WITH NAVIGATION SYSTEMNBHA0016S10Increases or decreases the set temperature.
AMB (AMBIENT) SWITCH (WITH NAVIGATION SYSTEM)NBHA0016S11Shows the ambient (outside) air temperature on the display screen for 5 seconds.
