Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EKS00BMY
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 Man-
ual.
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 must be per-
formed by an authorized NISSAN/INFINITI dealer.

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.

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.

PROPELLER SHAFT VIBRATION
NOTE:
If a vibration is present at high speed, inspect the propeller shaft run out first.
1. Measure the run out of the propeller shaft tube at several points
by rotating the final drive companion flange with your hands.
2. If the run out still exceeds specifications, disconnect the propel- ler shaft at the final drive companion flange; then rotate the com-
panion flange 90 °, 180 °, 270 ° degrees and reconnect the
propeller shaft.
3. Check the run out again. If the run out still exceeds specifica- tions, replace the propeller shaft assembly.
4. After installation, check for vibration by driving the vehicle.
INSPECTION
Inspect the propeller shaft tube for dents or cracks. If damaged, replace the propeller shaft assembly.

by rotating the final drive companion flange with your hands.
2. If the run out still exceeds specifications, disconnect the propel- ler shaft at the final drive companion flange; then rotate the com-
panion flange 90 °, 180 °, 270 ° degrees and reconnect propeller
shaft.
3. Check the run out again. If the run out still exceeds specifica- tions, replace the propeller shaft assembly.
