Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EBS00GUD

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 may include seat belt switch inputs and dual stage front air bag modules. If
equipped with 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.

The vehicle may be equipped with a passenger air bag deactivation switch. Because no rear seat exists where
a rear-facing child restraint can be placed, the switch is designed to turn off the passenger air bag so that a
rear-facing child restraint can be used in the front passenger seat. The switch is located in the center of the
instrument panel, near the ashtray. When the switch is turned to the ON position, the passenger air bag is
enabled and could inflate for certain types of collision. When the switch is turned to the OFF position, the pas-
senger air bag is disabled and will not inflate. A passenger air bag OFF indicator on the instrument panel lights
up when the passenger air bag is switched OFF. The driver air bag always remains enabled and is not affected
by the passenger air bag deactivation switch.

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 per-
formed by an authorized NISSAN/INFINITI dealer.
q Improper 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.
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.
q The vehicle may be equipped with a passenger air bag deactivation switch which can be operated
by the customer. When the passenger air bag is switched OFF, the passenger air bag is disabled
and will not inflate. When the passenger air bag is switched ON, the passenger air bag is enabled
and could inflate for certain types of collision. After SRS maintenance or repair, make sure the
passenger air bag deactivation switch is in the same position (ON or OFF) as when the vehicle
arrived for service.
Precautions for Liquid Gasket EBS00GUE

REMOVAL OF LIQUID GASKET
q After removing the mounting bolts and nuts, separate the mating
surface using a seal cutter and remove the sealant.
CAUTION:
Be careful not to damage the mating surfaces.
q In areas where the cutter is difficult to use, use a plastic hammer
to lightly tap the areas where the sealant is applied.
CAUTION:
If for some unavoidable reason a tool such as a flat-bladed
screwdriver is used, be careful not to damage the mating sur-
faces.

LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old sealant adhering to the mating A
surface.
q Remove the sealant completely from the groove, mounting
bolts, and bolt holes. LU
2. Clean the mating surface thoroughly to remove adhering mois-
ture, grease and foreign materials.
3. Install the sealant tube into the tube presser. C

4. Apply the sealant without breaks to the specified area with the
specified dimensions. E
q If there is a groove for the sealant application, apply the seal-
ant to the groove.

q As for the bolt holes, normally apply the sealant inside the
holes. If specified, it should be applied outside the holes.
Make sure to read the instructions in this manual. I
q Within five minutes of sealant application, install the mating
component.
q If the sealant protrudes, wipe it off immediately. J
q Do not retighten after the installation.

q After 30 minutes or more have passed from the installation, fill
the engine with the correct oil and coolant. Refer to MA-12, K
"Recommended Fluids and Lubricants" . SEM159F
CAUTION:
If there are specific instructions in the service manual, observe them. L
