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 AIR BAG” and “SEAT BELT” of this Service Manual. WARNING: • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that 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 “SRS AIR BAG”. • 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. PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition 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 3 minutes before performing any service.

Precaution Necessary for Steering Wheel Rotation after Battery Disconnect INFOID:0000000004960921 NOTE: • Before removing and installing any control units, first turn the push-button ignition switch to the LOCK position, then disconnect both battery cables. • After finishing work, confirm that all control unit connectors are connected properly, then re-connect both battery cables. • Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work. If a DTC is detected, perform trouble diagnosis according to self-diagnosis results. For vehicle with steering lock unit, if the battery is disconnected or discharged, the steering wheel will lock and cannot be turned. If turning the steering wheel is required with the battery disconnected or discharged, follow the operation procedure below before starting the repair operation. OPERATION PROCEDURE 1. Connect both battery cables. NOTE: Supply power using jumper cables if battery is discharged. 2. Turn the push-button ignition switch to ACC position. (At this time, the steering lock will be released.) 3. Disconnect both battery cables. The steering lock will remain released with both battery cables disconnected and the steering wheel can be turned. 4. Perform the necessary repair operation. 5. When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering wheel will lock when the push-button ignition switch is turned to LOCK position.) 6. Perform self-diagnosis check of all control units using CONSULT-III. Precaution for Procedure without Cowl Top Cover INFOID:0000000004960922 When performing the procedure after removing cowl top cover, cover the lower end of windshield with urethane, etc. PIIB3706J PREPARATION VTL-7 < PREPARATION > C D E F G H J K L M A B VTL N O P PREPARATION PREPARATION Commercial Service Tool INFOID:0000000004960923 Tool name Description Remover tool Remove clips, pawls, metal clips PIIB7923J VTL-8 < PERIODIC MAINTENANCE > AIR CONDITIONER FILTER PERIODIC MAINTENANCE AIR CONDITIONER FILTER Exploded View INFOID:0000000004960924 Removal and Installation INFOID:0000000004960925 REMOVAL 1.

Deformed/damaged filter may deteriorate the duct collecting performance. • When installing, handle the filter with extreme care to avoid deforming/damaging. • Never open the wrap until just before the installation. Because the high performance filter (for odors, pollen, and other allergens) immediately starts absorbing odors by opening the wrap to remove them. Replacement INFOID:0000000004960926 Replace air conditioner filter. Refer to MA-7, "Periodic Maintenance". Affix a caution label inside the glove box when replacing filter.
