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 malfunctioning.
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 (dis-
play unit).System is not malfunction.
Symptom Cause Remedy
Map screen and BIRDVIEW™
Name of the place varies with the
screen.Some thinning of the character data is done to pre-
vent 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 malfunctioning.
Vehicle mark is not positioned cor-
rectly.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 nighttime
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 adjust-
ment function.Perform screen dimming and select the
nighttime screen by “SWITCH SCREENS”.
Map screen will not scroll in accor-
dance with the vehicle travel.Current location is not displayed. Press “MAP” button to display the current lo-
cation.
Vehicle mark will not be shown. Current location is not displayed. Press “MAP” button to display the current lo-
cation.
Accuracy indicator (GPS satellite
mark) on the map screen stays
gray.GPS satellite signal is intercepted because the ve-
hicle is in or behind a building.Move the vehicle out to an open space.
GPS satellite signal cannot be received because
an obstacle is placed on top of the instrument pan-
el.Do not place anything in the center on top of
the display.
GPS satellites are not visible from current location. Wait until GPS satellites are visible by mov-
ing the vehicle.

CURRENT-LOCATION MARK SHOWS A POSITION WHICH IS COMPLETELY WRONG
In the following cases, the current-location mark may appear on completely different position in the map
depending on the GPS satellite signal receiving conditions. In this case, perform location correction and direc-
tion correction.
• When location correction has not been done
- If the receiving conditions of the GPS satellite signal is poor, or if the current-location mark becomes out of
place, it may move to a completely different location and not come back if location correction is not done.
The position will be corrected if the GPS signal can be received.
• When the vehicle has traveled by ferry, or when the vehicle has been towed
- Because calculation of the current location cannot be done when travelling with the ignition OFF, for exam-
ple when traveling by ferry or when being towed, the location before travel is displayed. If the precise loca-
tion can be detected with GPS, the location will be corrected.
CURRENT-LOCATION MARK JUMPS
In the following cases, the current-location mark may appear to jump as a result of automatic correction of the
current location.
• When map-matching has been done
- If the current location and the current-location mark are different when map-matching is done, the current-
location mark may seem to jump. At this time, the location may be “corrected” to the wrong road or to a loca-
tion which is not on a road.
• When GPS location correction has been done
- If the current location and the current-location mark are different when the location is corrected using GPS
measurements, the current-location mark may seem to jump. At this time, the location may be “corrected” to
a location which is not on a road.
CURRENT-LOCATION MARK IS IN A RIVER OR SEA
The navigation system moves the current-location mark with no distinction between land and rivers or sea. If
the location mark is somehow out of place, it may appear that the vehicle is driving in a river or the sea.
WHEN DRIVING ON SAME ROAD, SOMETIMES CURRENT-LOCATION MARK IS IN RIGHT
Precautions
for drivingJust after the engine is startedIf the vehicle is driven just after the engine
is started when the gyroscope (angular
speed sensor) correction is not completed,
the vehicle can lose its direction and may
have deviated from the correct location.Wait for a short while before
driving after starting the engine.
Continuous driving without stopping When driving long distances without stop-
ping, direction errors may accumulate, and
the current-location mark may deviate from
the correct road.Stop and adjust the orientation.
Abusive driving Spinning the wheels or engaging in other
kinds of abusive driving may result in the
system being unable perform correct detec-
tion, and may cause the vehicle mark to de-
viate from the correct road.If after travelling about 10 km (6
miles) the correct location has
not been restored, perform lo-
cation correction and, if neces-
sary, direction correction.
How to cor-
rect locationPosition correction accuracy
If the accuracy of location settings is poor,
accuracy may be reduced when the correct
road cannot be found, particularly in places
where there are many roads.Enter in the road displayed on
the screen with an accuracy of
approx. 1mm.
Caution: Whenever possible,
use detailed map for the correc-
tion.
Direction when location is corrected
If the accuracy of location settings during
correction is poor, accuracy may be re-
duced afterwards.Perform direction correction. Cause (condition) –: While driving ooo: Display Driving condition Remarks (correction, etc.)

PRECAUTIONS
• If YES, GO TO 2.
• If NO, GO TO 5.
2. Is there any indication other than indications relating to CAN communication system in the self-diagnosis
results?
• If YES, GO TO 3.
• If NO, GO TO 4.
3. Based on self-diagnosis results unrelated to CAN communication, carry out the inspection.
4. Malfunctions may be detected in self-diagnosis depending on control units carrying out CAN communica-
tion. Therefor, erase the self-diagnosis results.
5. Diagnose CAN communication system. Refer to LAN-7
.
Precaution for Brake ControlINFOID:0000000003532764
• During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is
normal.
• Just after starting vehicle, the brake pedal may vibrate or a motor operating noise may be heard from engine
compartment. This is a normal status of operation check.
• Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel, or
snow-covered (fresh, deep snow) roads.
• When an error is indicated by ABS or another warning lamp, collect all necessary information from customer
(what symptoms are present under what conditions) and check for simple causes before starting diagnosis.
Besides electrical system inspection, check booster operation, brake fluid level, and fluid leaks.
• If incorrect tire sizes or types are installed on the vehicle or brake pads are not Genuine NISSAN parts, stop-
ping distance or steering stability may deteriorate.
• If there is a radio, antenna or related wiring near control module, ABS function may have a malfunction or
error.
• If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits or improper wiring.
• If the following components are replaced with non-genuine components or modified, the VDC OFF indicator
lamp and SLIP indicator lamp may turn on or the VDC system may not operate properly. Components
related to suspension (shock absorbers, struts, springs, bushings, etc.), tires, wheels (exclude specified
size), components related to brake system (pads, rotors, calipers, etc.), components related to engine (muf-
fler, ECM, etc.), components related to body reinforcement (roll bar, tower bar, etc.).
• Driving with broken or excessively worn suspension components, tires or brake system components may
cause the VDC OFF indicator lamp and the SLIP indicator lamp to turn on, and the VDC system may not
operate properly.
• When the TCS or VDC is activated by sudden acceleration or sudden turn, some noise may occur. The
noise is a result of the normal operation of the TCS and VDC.
• When driving on roads which have extreme slopes (such as mountainous roads) or high banks (such as
sharp curves on a freeway), the VDC may not operate normally, or the VDC warning lamp and the SLIP indi-
cator lamp may turn on. This is not a problem if normal operation can be resumed after restarting the engine.
• Sudden turns (such as spin turns, acceleration turns), drifting, etc. with VDC turned off may cause the yaw
rate/side/decel G sensor to indicate a problem. This is not a problem if normal operation can be resumed
after restarting the engine.
Precaution for CAN SystemINFOID:0000000003532765
• Do not apply voltage of 7.0V or higher to terminal to be measured.
• Maximum open terminal voltage of tester in use must be less than 7.0V.
• Before checking harnesses, turn ignition switch OFF and disconnect battery negative cable.
