Map screen and BIRDVIEW™
Name of the place vary 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 on top of the meter dis-
play (instrument panel).
GPS satellites are not visible from current location. Wait until GPS satellites are visible by mov- ing the vehicle.
Vehicle location accuracy is low. Accuracy indicator (GPS sate llite mark) on the
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 fit-
ted or the system has been used on another vehi-
cle. 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 CONFIRMA-
TION/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.
Symptom
Cause Remedy
Destination cannot be set. Destination to be set is on an expressway. Set the destination on an ordinary road.
Passing point is not searched
when re-searching the route. The vehicle has already passed the passing point,
or the system judged so. To include the passing points that have been
passed into the route again, set the route
again.

Location Correction by Map-Matching is Slow
• The map-matching function needs to refer to the data of
the surrounding area. It is necessary to drive some
distance for the function to work.
• Because map-matching operates on this principle, when there are many roads running in similar directions
in the surrounding area, no matching determination ma y be made. The location may not be corrected until
some special feature is found.
Name of Road is Not Displayed
The current road name may not be displayed if there are no road names displayed on the map screen.
Contents of Display Differ for Birdview™ and the (Flat) Map Screen
Difference of the BIRDVIEW™ screen from the flat map screen are as follows.
• The current place name displays names which are primarily in the direction of vehicle travel.
• The amount of time before the vehicle travel or turn angle is updated on the screen is longer than for the
(flat) map display.
• The conditions for display of place names, roads, and other data are different for nearby areas and for more
distant areas.
• Some thinning of the character data is done to prevent the display becoming too complex. In some cases
and in some locations, the display contents may differ.
• The same place name, street name, et c. may be displayed multiple times.
Vehicle Mark Shows a Position Which is Completely Wrong
In the following cases, the vehicle 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 direction correction.
• When location correction has not been done
- If the receiving conditions of the GPS satellite signal is poor, if the vehicle 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 being towed
Precautions
for driving Just after the engine is started
If 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 location Position 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.

AV-160
< SYMPTOM DIAGNOSIS >[AUDIO SYSTEM]
NORMAL OPERATING CONDITION
- Because calculation of the current location cannot be
done when traveling with the ignition off, for example
when traveling by ferry or when being towed, the location before travel is displayed. If the precise location
can be detected with GPS, the location will be corrected.
Vehicle Mark Jumps
In the following cases, the vehicle mark may appear to ju mp as a result of automatic correction of the current
location.
• When map matching has been done
- If the current location and the vehicle mark are diff erent when map matching is done, the vehicle mark may
seem to jump. At this time, the location may be “corre cted” to the wrong road or to a location which is not on
a road.
• When GPS location correction has been done
- If the current location and the vehicle mark are different when the location is corrected using GPS measure-
ments, the vehicle mark may seem to jump. At this time, the location may be “corrected” to a location which
is not on a road.
Vehicle Mark is in a River or Sea
The navigation system moves the vehicle mark with no distinction between land and rivers or sea. If the vehi-
cle mark is somehow out of place, it may appear that the vehicle is driving in a river or the sea.
Vehicle Mark Automatically Rotates
The system wrongly memorizes the rotating status as st opping when the ignition switch is turned ON with the
turntable rotating. That causes the vehicle mark to rotate when the vehicle is stopped.
When Driving on Same Road, Sometimes Vehicle Mark is in Right Place and Sometimes it is in Wrong Place
The conditions of the GPS antenna (GPS data) and gyroscope (angular speed sensor) change gradually.
Depending on the road traveled and the operation of the steering wheel, \
the location detection results will be
different. Therefore, even on a road on which the lo cation has never been wrong, conditions may cause the
vehicle mark to deviate.

Precaution for Brake SystemINFOID:0000000001604543
CAUTION:
• Always use recommended brake fluid. Refer to MA-12, "
Fluids and Lubricants".
• Never reuse drained brake fluid.
• Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, wash it away with water immediately.
• To clean or wash all parts of master cylin der and disc brake caliper, use clean brake fluid.
• Never use mineral oils such as gasoline or kerosen e. They will ruin rubber parts of the hydraulic sys-
tem.
• Use flare nut wrench when removing and installing brake
tube.
• If a brake fluid leak is found, the part must be disassembled
without fail. Then it has to be replaced with a new one if a
defect exists.
• Turn the ignition switch OFF and remove the connector of the ABS actuator and electric unit (con trol unit) or the battery ter-
minal before performing the work.
• Always torque brake lines when installing.
• Burnish the brake contact surf aces after refinishing or replac-
ing rotors, after replacing pads, or if a soft pedal occurs at
very low mileage.
Refer to BR-30, "
Brake Burnishing Procedure" (front disc brake) or BR-35, "Brake Burnishing Proce-
dure" (rear disc brake).
WARNING:
• Clean brake pads and shoes with a waste cl oth, then wipe with a dust collector.
Precaution for Brake ControlINFOID:0000000001604544
• 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 boos ter 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, roto rs, 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 suspensi on 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 no rmally, 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.
