2003 NISSAN ALMERA N16 steering wheel

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.
THE CURRENT LOCATION MARK IS IN A RIVER OR THE SEA.NJEL0633S09The navigation system moves the current location mark with no distinctionbetween 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 THE SAME ROAD, SOMETIMES THE CURRENT-LOCATION MARK IS IN
THE RIGHT PLACE AND SOMETIMES IT IS THE WRONG PLACE.
NJEL0633S10The 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, thelocation 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.NJEL0633S11The 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 roadsrunning in similar direc-
tions in the surrounding area, no matching determination may be made. The location may not be corrected
until some special feature is found.
ALTHOUGH THE GPS RECEIVING DISPLAY IS GREEN, THE VEHICLE MARK DOES NOT
RETURN TO THE CORRECT LOCATION.
NJEL0633S12The GPS accuracy has an error of about 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 withthe results from map-match-
ing location detection. The one which is determined to have higher accuracyisused.
GPS location correction may not be performed when the vehicle is stopped.
THE NAME OF THE CURRENT PLACE IS NOT DISPLAYED.NJEL0633S13The current place name may not be displayed if there are no place names displayed on the map screen.
CONTENTS OF THE DISPLAY DIFFER FOR THE BIRDVIEW AND THE (FLAT) MAP
SCREEN.
NJEL0633S14Difference of the BIRDVIEW Screen From the Flat Map Screen Are as Follows.NJEL0633S1401The current place name displays names which are primarily in the directionof 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 becomingto 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.

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”
GI-22, “HOW TO PERFORM EFFICIENT DIAGNOSES FOR AN ELECTRICAL INCIDENT”

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.
