Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER"
NKS002ZB
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 Manual.
WARNING: q 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.
q 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.
q 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 harness connectors.

LANE DEPARTURE WARNING SYSTEM Precautions for Lane Departure Warning (LDW) system
PFP:28442
A
NKS00311
WARNING: Lane Departure Warning (LDW) is only a warning device to inform the driver of an unintended lane B departure. It will not steer the vehicle or prevent loss of control. It is the driver's responsibility to stay alert, drive safely, keep the vehicle in the traveling lane, and be in control of the vehicle at all times.
q LDW system does not operate under the following conditions:
C
At speeds below approx. 72 km/h (45 MPH).
If it cannot detect lane markers.
q LDW system may not function properly under the following conditions:
D
On roads where a water puddle, dirt or snow is covering the lane markers.
On roads where the lane markers are faded or are not painted clearly.
On roads where the lane markers are painted yellow.
E
q LDW system may not monitor the lane markers in certain road, weather or driving conditions.
On roads where there are sharp curves.
Where the traveling lane merges or separates.
F
On roads where the discontinued lane markers are present, such as near tollgates, etc.
On roads where there are not general lane markers.
G
On roads where the lane width is too narrow.
During bad weather (rain, fog, snow, etc.).
When strong light (for example, at sunrise or sunset) is directly shining on the front of the vehicle. H
When entering or exiting a tunnel where sudden changes in brightness occur.
When traveling close to the vehicle in front of you, which causes obstruction of the camera unit
range.
I
When the vehicle's traveling direction does not align with the lane marker.
When rain, snow or dirt adhere to the windshield in front of the camera unit.
q Excessive noise interferes with warning system chime sound and the chime may not be heard.
J
CAUTION: To keep the LDW system operating properly, be sure to observe the following: q Always keep the windshield clean. The sensing capability of the camera unit depends on the con- DI
dition of the windshield. See "Appearance and care" for cleaning instruction.
q Never strike or damage the areas around the camera unit.
q Never touch the camera lens.
L
q Never attach a sticker (including transparent material) or install an accessory near the camera unit. M
q Never place reflective materials, such as a white paper or mirrors on the instrument panel. Reflection of the sunlight may adversely affect the camera unit's lane marker detection capability.
System Description
LDW SYSTEM OPERATION
NKS00312
q The Lane Departure Warning (LDW) system warns the driver when the vehicle is traveling close to either the left or the right of the traveling lane.
q The system monitors lane markers of the traveling lane using the LDW camera unit. When the LDW camera unit detects that the vehicle is traveling close to either the left or the right of the traveling lane, the LDW indicator lamp flashes and a chime sounds to alert the driver.
NOTE: When activating turn signal, LDW system does not give a warning to the lane marker on the turn signal side.
q The LDW system can be turned on or off by pushing the LDW switch. When the system is on, the LDW system ON indicator illuminates.
q The LDW system has an automatic mode and manual mode.
Revision: 2006 July
DI-77
2007 FX35/FX45
LANE DEPARTURE WARNING SYSTEM
In the automatic mode LDW system automatically turns on, when the ignition switch is turned to the ON position. LDW system ON indicator located on the LDW switch illuminates, indicating that the system is on. To cancel LDW system, push the LDW switch to turn off LDW system ON indicator. To turn on the system, push LDW switch again. In the manual mode LDW system is still off when the ignition switch is turned to the ON position. The LDW switch must be pushed to turn on the system. To the change modes Push and hold LDW switch for more than 4 seconds, when LDW system ON indicator is off. Then LDW chime sounds and blinking of LDW system ON indicator informs that the mode change is com-
pleted. q Temporary disabled status at high temperature If the vehicle is parked in direct sunlight under high temperature conditions [approximately over 104°F
(40°C)] and then started, the LDW system may sound a chime and cancel automatically. Then LDW system ON indicator will blink. When the interior temperature is reduced, the system will resume to operate automatically and the LDW system ON indicator illuminates.

CAN COMMUNICATION
CAN COMMUNICATION System Description
PFP:23710
A
NKS003HO
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec- B tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

NOTE: q Do not install the ski rack, antenna, etc. which is attach to the vehicle with a magnet base. It affects the
operation of the compass.
q When cleaning the mirror, use a paper towel or similar material dampened with glass cleaner. Do not spray glass cleaner directly on the mirror as it may cause the liquid cleaner to enter the mirror housing.
System Description
NKS003HR
q This electronic compass is able to display 8 primary directions: N, NE, E, SE, S, SW, W, NW.
q The inside mirror switch (2) is used to operate the compass and automatic anti-glare system.

NOTE: For further details of the compass and automatic anti-glare system, refer to Owner's Manual
q All standard compasses determine direction relative to Magnetic North; however, this electronic compass is designed to display direction relative to True North.
q The difference between Magnetic North and True North varies from place to place across the surface of the earth.
q This electronic compass must be "told" approximately where it is on the earth's surface so that the Magnetic North reading can be properly converted into a True North display.
q To tell the electronic compass where it's at, the earth is separated into numbered "Zone Variances". The Zone Variance number in which the compass is to function must be entered into this electronic compass.
q Each zone is magnetically about 4.2° wide. Typically, anything under 22.5° total zone change is not noticed on the electronic compass display. However, over 22.5°, a reading may be off by one or more primary directions.
q On long trips, a vehicle may leave its original zone and enter one or more new zones. Generally, you do not need to reset the compass zone if you travel between 3 or 4 zones, such as business travel or vacation. The typical driver will not notice any difference on the display within 3 or 4 zones. However, if the vehicle is "permanently" moved to a new location, it is recommended that the compass zone be reset.

Troubleshooting
NKS003HS
q The electronic compass is highly protected from changes in most magnetic fields. However, some large A
changes in magnetic fields can affect it. Some examples are (but not limited to): high tension power lines,
large steel buildings, subways, steel bridges, automatic car washes, large piles of scrap metal, etc. While
this does not happen very often, it is possible.
B
q During normal operation, the Compass Mirror will continuously update the compass calibration to adjust for gradual changes in the vehicle's magnetic "remnant" field. If the vehicle is subjected to high magnetic influences, the compass may appear to indicate false headings, become locked, or appear that it is C unable to be calibrated. If this occurs, perform the calibration procedure.
q If at any time the compass continually displays the incorrect direction or the reading is erratic or locked,
verify the correct zone variance.

NOTE: The zone setting is factory preset ("default" setting) to zone 8. 1. Press and hold the inside mirror switch for 6 9 seconds. 2. The current zone setting appears on the compass display. 3. Find the current geographical location number in the Zone Varia-
tion Chart. 4. Select the new zone number. (Press the inside mirror switch
until the new zone number appears on the compass display.) 5. After select the new zone number, the compass display will
automatically shows a direction within a few seconds. 6. Preform the following Calibration Procedure for more accurate
indications.
NKS003HT
SEL168Y
Calibration Procedure
NKS003HU
NOTE: The compass calibrates itself under normal driving conditions. However, occasional circumstances may cause the compass to operate inaccurately. Example: Driving from rural (wide open) areas to crowded city areas, or if an aftermarket (i.e., non original equipment) antenna with a magnetic base is attached to the vehicle. Calibrate the mirror compass if the display shows only one direction or a limited number of directions.
NOTE: q If "magnetic hats" are used in the dealership for vehicle identification, remove the hat from the vehicle
before performing the following steps. Do NOT put the hat back on the vehicle after the procedure is completed.
q Drive the vehicle to an open level area; away from large metallic objects, structures, and overhead power lines.
q Turn off "non-essential" electrical accessories (rear window defrost, heater/air conditioning, wipers) and close the doors.
1. Verify the correct compass zone setting for the geographical location. Refer to DI-108, "Zone Variation Setting Procedure" .
2. Press and hold the inside mirror switch for more than 9 seconds.
3. "C" is displayed on the compass display, when calibration starts.
4. Drive slowly [less than 8 km/h (5 mph)] in a circle until the "C / CAL" is replaced with primary headings (N, NE, E, SE, S, SW, W, or NW).
NOTE: This will require driving at least 2 complete 360 degree circles; 3 complete circles may be required.
5. The compass calibration procedure is now complete. The compass should operate normally.
NOTE: If at any time the compass continually displays the incorrect direction or the reading is erratic or locked, repeat the calibration procedure.
