Example of Symptoms Judged Not AbnormalNJEL0633BASIC OPERATIONNJEL0633S01
Symptom Cause Remedy
No image is shown. Display brightness adjustment is set fully to
DARK side.Adjust the display brightness.
No guide sound is heard.
Audio guide volume is too low or
too high.Volume control is set to OFF, MIN or MAX. Adjust the audio guide volume.
Audio guidance is not available while the vehicle
is driving on a dark pink route.System is not malfunction.
Screen is too dark.
Motion of the image is too slow.Temperature inside the vehicle is low. Wait until the temperature inside the vehicle
reaches the proper temperature.
Small black or bright spots
appear on the screen.Symptom peculiar to a liquid crystal display. System is not malfunction.
VEHICLE MARKNJEL0633S02
Symptom Cause Remedy
Map screen and BIRDVIEW
Name of the place vary with the
screen.Some thinning of the character data is done to
prevent the display becoming to complex. In
some cases and in some locations, the display
contents may differ.
The same place name, street name, etc. may
not be displayed every time on account of the
data processing.System is not malfunction.
Vehicle mark is not positioned
correctly.Vehicle is transferred by ferry or by towing after
its ignition switch is turned to OFF.Drive the vehicle for a while in the GPS sat-
ellite signal receiving condition.
Screen will not switch to night-
time mode after the lighting
switch is turned ON.The daytime screen is selected by the “SWITCH
SCREENS” when the last time the screen dim-
ming setting is done.
Switching between daytime/nighttime screen
may be inhibited by the automatic illumination
adjustment function.Perform screen dimming and select the
nighttime screen by “SWITCH SCREENS”.
Map screen will not scroll in
accordance with the vehicle
travel.Current location is not displayed. Press “MAP” switch to display the current
location.
Vehicle mark will not be shown. Current location is not displayed. Press “MAP” switch to display the current
location.
Accuracy indicator (GPS satellite
mark) on the map screen stays
gray.GPS satellite signal is intercepted because the
vehicle is in or behind a building.Move the vehicle out to an open space.
GPS signal cannot be received because some-
thing is placed on driver’s side instrument panel.Do not place anything on driver’s side
instrument panel.
GPS satellites are located badly. Wait until the location becomes better.
Vehicle location accuracy is low. Accuracy indicator (GPS satellite mark)onthe
map screen stays gray.Current location is not determined.
Vehicle speed setting by the vehicle speed pulse
has been deviated (advanced or retarded) from
the actual vehicle speed because tire chain is
fitted or the system has been used on another
vehicle.Drive the vehicle for a while [for approx. 30
minutes at approx. 30 km/h(19 MPH)] and
the deviation will be automatically adjusted.
If advancement or retard still occur, perform
the distance adjustment by
CONFIRMATION/ADJUSTMENT mode of
diagnosis function.
Map data has error or omission. (Vehicle mark is
always deviated to the same position.)As a rule, an updated map DVD-ROM will
be released once a year.

INSTALLATIONNJRS00171. Set the front wheels in the straight-ahead position.
2. Make sure that the spiral cable is in the neutral position.
The neutral position is detected by turning left about 3.5 revo-
lutions from the right end position. Align the two marks (
)or
make sure that the white indicator is visible in the upper part
of the indicator window, with the cable pointed downwards.
CAUTION:
The spiral cable may snap due to steering operation if the
cable is installed in an improper position.
Also, with the steering linkage disconnected, the cable
may snap by turning the steering wheel beyond the limited
number of turns. The spiral cable can be turned up to
about 3.5 turns from the neutral position to both the right
and left.
3. Connect spiral cable connector and tighten with screws. Install
steering column cover.
4. Install steering wheel, aligning with spiral cable pin guides, and
pull spiral cable through.
5. Connect horn/audio connector and engage spiral cable with
pawls in steering wheel. Move driver air bag module connec-
tor away from steering wheel lower lid opening.
6. Tighten nut.

10. Install the air bag module, press the center of the horn pad to
make contact (RH/LH) ON.
11. Conduct self-diagnosis to ensure entire SRS operates prop-
erly. (Use CONSULT-II or warning lamp check.)
Before performing self-diagnosis, connect both battery cables.
12. Turn steering wheel to the left end and then to the right end
fully to make sure that spiral cable is set in the neutral posi-
tion.
If “AIR BAG” warning lamp blinks or stays ON (at the user
mode), it shows the spiral cable may be snapped due to its
improper position. Perform self-diagnosis again (use CON-
SULT-II or warning lamp). If a malfunction is detected, replace
the spiral cable with a new one.
13. Perform self-diagnosis again to check that no malfunction is
detected.
