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.)

NAVIGATION SYSTEM
PLACE AND SOMETIMES IT IS 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 location has never been wrong, conditions may cause the
vehicle mark to deviate.
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 may be made. The location may not be corrected until
some special feature is found.
ALTHOUGH GPS RECEIVING DISPLAY IS GREEN, VEHICLE MARK DOES NOT RETURN TO
CORRECT LOCATION
• The GPS accuracy has an error of approximately 10 m (30 ft). In some cases the current-location mark may
not be on the correct street, even when GPS location-correction is done.
• The navigation system compares the results of GPS location detection with the results from map-matching
location detection. The one which is determined to have higher accuracy is used.
• GPS location correction may not be performed when the vehicle is stopped.
NAME OF CURRENT PLACE IS NOT DISPLAYED
The current place name may not be displayed if there are no place 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, etc. may be displayed multiple times.

the new parts. Select an excellent anti-corrosive wax which will penetrate after application and has a long shelf
life.
UNDERCOATING
The underside of the floor and wheelhouse are undercoated to prevent rust, vibration, noise and stone chip-
ping. Therefore, when such a panel is replaced or repaired, apply undercoating to that part. Use an undercoat-
ing which is rust preventive, soundproof, vibration-proof, shock-resistant, adhesive, and durable.
Precautions in undercoating
1. Do not apply undercoating to any place unless specified (such as the areas above the muffler and three
way catalyst which are subjected to heat).
2. Do not undercoat the exhaust pipe or other parts which become hot.
3. Do not undercoat rotating parts.

PRECAUTIONS
SERVICE INFORMATION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003532717
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SRS section.
• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.
Precaution for Brake SystemINFOID:0000000003532718
• Always use recommended brake fluid. Refer to MA-10 .
• Do not reuse drained brake fluid.
• Be careful not to splash brake fluid on painted areas.
• To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use clean brake fluid.
• Do not use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.
• Use flare nut wrench when removing and installing brake tube.
• Always check tightening torque when installing brake lines.
• Before working, turn ignition switch to OFF and disconnect con-
nectors for ABS actuator and electric unit (control unit) or battery
terminals.
• Burnish the brake contact surfaces after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage.
Refer to BR-20, "
Disassembly and Assembly of Brake Caliper" .
WARNING:
• Clean brake pads and shoes with a waste cloth, then wipe
with a dust collector.
