Bulb ReplacementNJEL0015The headlamp is a semi-sealed beam type which uses a replace-
able halogen bulb. The bulb can be replaced from the engine com-
partment side without removing the headlamp body.
Grasp only the plastic base when handling the bulb. Never
touch the glass envelope.
1. Disconnect the battery cable.
2. Pull off the rubber cap.
3. Disconnect the harness connector from the back side of the
bulb.
4. Remove the bulb retaining ring.
5. Remove the headlamp bulb carefully. Do not shake or rotate
the bulb when removing it.
6. Install in the reverse order of removal.
CAUTION:
Do not leave headlamp reflector without bulb for a long period
of time. Dust, moisture, smoke, etc. entering headlamp body
may affect the performance of the headlamp. Remove head-
lamp bulb from the headlamp reflector just before a replace-
ment bulb is installed.
Aiming AdjustmentNJEL0016For details, refer to the regulations in your own country.
Before performing aiming adjustment, check the following.
1) Keep all tires inflated to correct pressures.
2) Place vehicle on flat surface.
3) See that there is no-load in vehicle (coolant, engine oil filled up
to correct level and full fuel tank) other than the driver (or
equivalent weight placed in driver’s position).
SEL984W
CAUTION:
Be sure aiming switch is set to “0” when performing aiming
adjustment on vehicles equipped with headlamp aiming con-
trol.

SKIA0370E
System DescriptionNJEL0592The navigation system periodically calculates the vehicle’s current
position according to the following three signals: Travel distance of
the vehicle as determined by the vehicle speed sensor, turning
angle of the vehicle as determined by the gyroscope (angular
velocity sensor), and the direction of vehicle travel as determined
by the GPS antenna (GPS information).
The current position of the vehicle is then identified by comparing
the calculated vehicle position with map data read from the map
DVD-ROM, which is stored in the DVD-ROM drive (map-matching),
and indicated on the screen with a current-location mark.
SEL684V
By comparing the vehicle position detection results found by the
GPS and by map-matching, more accurate vehicle position data
canbeused.
The current vehicle position will be calculated by detecting the dis-
tance the vehicle moved from the previous calculation point and its
direction.
TRAVEL DISTANCENJEL0592S01Travel distance calculations are based on the vehicle speed sen-
sor input signal. Therefore, the calculation may become incorrect
as the tires wear down. To prevent this, an automatic distance fine
adjustment function has been adopted.
TRAVEL DIRECTIONNJEL0592S02Change in the travel direction of the vehicle is calculated by a
gyroscope (angular velocity sensor) and a GPS antenna (GPS
information). As the gyroscope and GPS antenna have both merit
and demerit, input signals from them are prioritized in each situa-
tion. However, this order of priority may change in accordance with
more detailed travel conditions so that the travel direction is
detected more accurately.
Type Advantage Disadvantage
Gyroscope (angular velocity sen-
sor)Can detect the vehicle’s turning angle
quite accurately.Direction errors may accumulate when the
vehicle is driven for long distances without
stopping.
GPS antenna (GPS information)Can detect the vehicle’s travel direction
(North/South/East/West).Correct direction cannot be detected when
the vehicle speed is low.
SEL685V
MAP-MATCHINGNJEL0592S03Map-matching is a function that repositions the vehicle on the road
map when a new location is judged to be the most accurate. This
is done by comparing the current vehicle position, calculated by the
method described in the position detection principle, with the road
map data around the vehicle, read from the map DVD-ROM stored
in the DVD-ROM drive.
Therefore, the vehicle position may not be corrected after the
vehicle is driven over a certain distance or time in which GPS
information is hard to receive. In this case, the current-location
mark on the display must be corrected manually.

Precautions
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) “AIR BAG” AND “SEAT BELT
PRE-TENSIONER”
NJRS0006The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER” used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of
collision. The SRS composition which is available to NISSAN MODEL N16 is asfollows (The composition
varies according to the destination and optional equipment.):
For a frontal collision
The Supplemental Restraint System consists of driver’s air bag module (located in the center of the steer-
ing wheel), front passenger air bag module (located on the instrument panel on passenger side), front seat
belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
For a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of front
seat), side air bag (satellite) sensor, diagnosis sensor unit (one of components of air bags for a frontal
collision), wiring harness, warning lamp (one of components of air bags for a frontal collision).
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 should be per-
formed by an authorized NISSAN dealer.
Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
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 harness connec-
tor.
PRECAUTIONS FOR SRS “AIR BAG” AND “SEAT BELT PRE-TENSIONER” SERVICENJRS0007Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
Before servicing the SRS, turn ignition switch “OFF”, disconnect both battery cables and wait at least 3
minutes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.
Diagnosis sensor unit must always be installed with their arrow marks “g” pointing towards the front of
the vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before
installation and replace as required.
The spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt to
turn steering wheel or column after removal of steering gear.
Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad
side facing upward and place front side air bag module standing with stud bolt side setting bottom.
Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
After air bag inflates, the front instrument panel assembly should be replaced if damaged.
WIRING DIAGRAMS AND TROUBLE DIAGNOSISNJRS0008When you read wiring diagrams, refer to the following:
GI-12, “HOW TO READ WIRING DIAGRAMS”
EL-12, “POWER SUPPLY ROUTING” for power distribution circuit
When you perform trouble diagnosis, refer to the following:
GI-33, “HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES”
