4 PRECUTIS PRECUTIS PFP:00001 Precautions for Supplemental Restraint System (SRS) IR G and SET ELT PRE-TENSIER EKS008RD The Supplemental Restraint System such as IR G and SET ELT PRE-TENSIER, 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 S section of this Service Manual. WRNING: 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 NISSN/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 ir ag 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. V-4

Then audio signals are supplied through satellite radio tuner terminals 21, 22, 23, and 24 to audio unit terminals 41, 42, 43, and 44. SPEED DEPENDENT VOLUME CTROL If activated, the radio output volume will be automatically adjusted to compensate for increased driving noises at higher driving speeds. The radio receives a vehicle speed signal from the combination meter, and selects the output volume. STEERING WHEEL UDIO CTROL SWITCHES (MIDLINE ND OSE SYSTEM) When one of the steering wheel audio control switches is pushed, the resistance in steering switch circuit changes depending on which button is pushed.

34 V Switch Self-Diagnosis Function UDIO EKS008RO It can check /OFF operation of each switch in the audio unit (without NVI) or V switch (with NVI) and diagnose the input signals from the steering switch (with NVI) (except TRIP on the steering wheel audio control switch). STRTING THE SELF-DIGNOSIS MODE (WITHOUT NVI) 1. Turn ignition switch from OFF to CC. 2. Press and hold the CLOCK switch and turn the volume control dial clockwise or counterclockwise for 30 clicks or more. WKI1935E Then the self-diagnosis initiates. 3. Initially, all display segments will be illuminated. 4. Then the current software version will be displayed when the "TUNE UP" switch is pressed. 5. Then a speaker check will occur when the "TUNE DOWN" switch is pressed. The audio unit will send a series of three beeps to each speaker channel in the following sequence: FR FL RL RR. This check will continue until any switch (except "TUNE UP", "TUNE DOWN" or volume) is operated. 6. Press each audio unit switch (except "TUNE UP", "TUNE DOWN" or volume). When each switch is pressed, a series of three beeps will sound. NOTE: Steering wheel audio control switches (except base), "TUNE UP", "TUNE DOWN" and volume switches are not included in this test. STRTING THE SELF-DIGNOSIS MODE (WITH NVI) 1. Turn ignition switch from OFF to CC. 2. Within 10 seconds press and hold the switches PUSE/MUTE and PREV simultaneously for 3 seconds. Then the self-diagnosis initiates. single beep indicates selfdiagnosis mode is active. 3. Press each switch and listen for beep. NOTE: TRIP button on steering wheel audio control switch and CD player LOD and EJECT buttons are not included in this test and will not beep when pressed. WKI2679E EXITING THE SELF-DIGNOSIS MODE Turn ignition switch OFF. Then the self-diagnosis ends. On models without NVI, pressing the volume switch will also exit the self-diagnosis mode.
