Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EKS003KR
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WA RN ING:
lTo 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 per-
formed by an authorized NISSAN/INFINITI dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
lDo 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 harness connectors.
PrecautionEKS003KS
lDo not touch the glass of bulb directly by hand. Keep grease and other oily matters away from it. Do not
touch bulb by hand while it is lit or right after being turned off. Burning may result.
lDo not leave bulb out of headlamp reflector for a long time because dust, moisture smoke, etc. may affect
the performance of the headlamp. When replacing the bulb, be sure to replace it with a new one.
lAdjust aiming by tightening aiming screw. (To adjust it toward loosening side, first loosen adjusting screw,
and then make adjustment by tightening.)
lTo remove soil or sealant of bulbs, do not use organic solvent (thinner, gasoline, etc.)
lWhen replacing bulb, be sure to hold bulb socket and pull it out straight. If wiring harness of the bulb is
pulled at an angle, the bulb may be caught in the lamp, making it difficult to take out.

System DescriptionEKS003CD
DESCRIPTION
The headlamps are controlled by the lighting switch which is built into the combination switch.
Power is supplied at all times
lto lighting switch terminal 8
lthrough 15A fuse (No. 40, located in the fuse and fusible link box), and
lto lighting switch terminal 5
lthrough 15A fuse (No. 41, located in the fuse and fusible link box).
LOW BEAM OPERATION
When the lighting switch is turned to the 2ND position and placed in LOW (“B”) position, power is supplied
lfrom lighting switch terminal 10
lto terminal 3 of the headlamp LH, and
lfrom lighting switch terminal 7
lto terminal 3 of the headlamp RH.
Terminal 2 of each headlamp supplies ground through body grounds E24 and E50.
With power and ground supplied, the low beams will illuminate.

When the lighting switch is turned to the 2ND position and placed in HIGH (“A”) position or PASS (“C”) posi-
tion, power is supplied
lfrom lighting switch terminal 6
lto terminal 1 of headlamp RH, and
lfrom lighting switch terminal 9
lto terminal 1 of headlamp LH, and
lto combination meter terminal 61 (LHD models) or 50 (RHD models) for the HIGH BEAM indicator.
Ground is supplied to terminal 60 (LHD models) or 49 (RHD models) of the combination meter through body

Aiming AdjustmentEKS003CG
When performing headlamp aiming adjustment, use an aiming machine, aiming wall screen or headlamp
tester. Aimers should be in good repair, calibrated and operated in accordance with respective operation man-
uals.
If any aimer is not available, aiming adjustment can be done as follows:
For details, refer to the regulations in your own country.
lKeep all tires inflated to correct pressures.
lPlace vehicle and tester on one and same flat surface.
lSee 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).
