ST-4 < PRECAUTION > [WITH HEATED STEERING WHEEL] PRECAUTIONS 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 SR 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 performed by an authorized NISSAN/INFINITI dealer. • 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 SR 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 har- ness connectors. PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: • When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni- tion ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the battery and wait at least three minutes before performing any service. Precaution for Removing 12V Battery INFOID:0000000010119071 1. Check that EVSE is not connected. NOTE: If EVSE is connected, the air conditioning system may be automatically activated by the timer A/C func- tion. 2. Turn the power switch OFF → ON → OFF. Get out of the vehicle. Close all doors (including back door). 3. Check that the charge status indicator lamp does not blink and wait for 5 minutes or more. NOTE: If the battery is removed within 5 minutes after the power switch is turned OFF, plural DTCs may be detected. 4. Remove 12V battery within 1 hour after turning the power switch OFF → ON → OFF. NOTE: • The 12V battery automatic charge control may start automatically even when the power switch is in OFF state. • Once the power switch is turned ON → OFF, the 12V battery automatic charge control does not start for approximately 1 hour. CAUTION: • After all doors (including back door) are closed, if a door (including back door) is opened before battery terminals are disconnected, start over from Step 1. • After turning the power switch OFF, if “Remote A/C” is activated by user operation, stop the air conditioner and start over from Step 1. Service Notice or Precautions for Steering System INFOID:0000000010119072 • In case of removing steering gear assembly, make the final tightening with grounded and unloaded vehicle condition, and then check wheel alignment. • Observe the following precautions when disassembling. - Before disassembly, thoroughly clean the outside of the unit. - Disassembly should be done in a clean work area. It is important to prevent the internal parts from becoming contaminated by dirt or other foreign matter. - For easier and proper assembly, place disassembled parts in order on a parts rack. - Use nylon cloth or paper towels to clean the parts; common shop rags can leave lint that might interfere with their operation. - Never reuse non-reusable parts. - Before assembling, apply the specified grease to the directed parts. |
