PRECAUTIONS
PRECAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EIS00CE9
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.
WARNING:
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 and/or orange harnesses or
harness connectors.
PrecautionsEIS00B92
lDisconnect both battery cables in advance.
lNever tamper with or force air bag lid open, as this may adversely affect air bag performance.
lBe careful not to scratch pad and other parts.
lWhen removing or disassembling any part, be careful not to damage or deform it. Protect parts which may
get in the way with cloth.
lWhen removing parts with a screwdriver or other tool, protect parts by wrapping them with vinyl or tape.
lKeep removed parts protected with cloth.
lIf a clip is deformed or damaged, replace it.
lIf an unreusable part is removed, replace it with a new one.
lTighten bolts and nuts firmly to the specified torque.
lAfter re-assembly has been completed, make sure each part functions correctly.
lRemove stains in the following way.
Water-soluble stains:
Dip a soft cloth in warm water, and then squeeze it tightly. After wiping the stain, wipe with a soft dry cloth.
Oil stain:
Dissolve a synthetic detergent in warm water (density of 2 to 3% or less), dip the cloth, then clean off the stain
with the cloth. Next, dip the cloth in fresh water and squeeze it tightly. Then clean off the detergent completely.
Thenwipetheareawithasoftdrycloth.
lDo not use any organic solvent, such as thinner or benzine.

MEMORY RESET PROCEDURE
1. Please observe the following instructions while confirming the sunroof operation.
NOTE:
Do not disconnect the electronic power while the sunroof is operating or within 5 seconds after the sunroof
stops. (to wipe-out the memory of lid position and operating friction.)
2. Initialization of system should be conducted after the following conditions.
lWhen the battery is out or connector is disconnected while sunroof is operating or within 5 seconds
after sunroof stops.
lWhen the sunroof motor is changed.
lWhen an emergency handle is used.
lWhen the sunroof does not operate normally. (Incomplete initialization conditions)
INITIALIZATION PROCEDURE
If sunroof does not close or open normally, use following procedure to return sunroof operation to normal.
1. Close sunroof if it is not in close position. It may be necessary to repeatedly push TILT UP/SLIDE CLOSE
switch to close sunroof.
2. Tilt up sunroof, and release TILT UP/SLIDE CLOSE switch once.
3. Keep pushing TILT UP/SLIDE CLOSE switch. After 10seconds, glass lid will back up a few millimeters.
then will be stopped at normal tilt up position.
(Keep pushing TILT UP/SLIDE CLOSE switch during this operation.)
4. Within first 10 seconds of releasing TILT UP/SLIDE CLOSE switch, keep pushing TILT UP/SLIDE CLOSE
switch again. After 4 seconds, glass lid will be automatically TILT DOWN®SLIDE OPEN®SLIDE
CLOSE.
(Keep pushing TILT UP/SLIDE CLOSE switch during this operation.)
5. After glass lid stops, release TILT UP/SLIDE CLOSE switch later 0.5 seconds.
6. Initializing procedure is completed. Confirm proper operation of sunroof (slide open, slide close, tilt up, tilt
down).
