6 PRECUTIONS < PRECUTION > [UTOMTIC IR CONDITIONING] PRECUTION PRECUTIONS Precaution for Supplemental Restraint System (SRS) "IR G" and "SET ELT PRE-TENSIONER" INFOID: The Supplemental Restraint System such as IR G and SET ELT 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 IR G and SET ELT 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 that 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 IR G. 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. PRECUTIONS WHEN USING POWER TOOLS (IR OR ELECTRIC) ND HMMERS WRNING: When working near the ir ag Diagnosis Sensor Unit or other ir ag 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. HC-6

21 SYSTEM < SYSTEM DESCRIPTION > [UTOMTIC IR CONDITIONING] /C auto amp. changes gate voltage to power transistor and controls air flow in 31 stages based on target air flow. When air flow is to be increased, gate voltage to power transistor increases gradually for preventing excessive large amount of air flow. In addition to manual control and automatic control, air flow control is consist of low coolant temperature starting control, fan speed control at door motor operation and fan speed control at voice recognition. UTOMTIC IR FLOW CONTROL /C auto amp. decides target air flow depending on target air mix door opening angle. /C auto amp. changes voltage to power transistor gate and controls air flow in 31 stages, so that target air flow is achieved. When air outlet is VENT or /L, the minimum air flow is changed depending on sunload. C D E F LOW COOLNT TEMPERTURE STRTING CONTROL /C auto amp. does not operate bower motor when engine coolant temperature is approximately 37 C (99 F) or less, for preventing a cold discharged air flow. fter this, gate voltage applied to power transistor gradually, and blower motor operates. FN SPEED CONTROL T DOOR MOTOR OPERTION When mode door motor is activated while air flow is more than the specified value, /C auto amp. reduces temporarily fan speed so that mode door moves smoothly. FN SPEED CONTROL T VOICE RECOGNITION When the voice control (voice command) switch is operated during air flow automatic control, /C auto amp. decreases the air flow of the blower motor once and controls the air flow so as not to disturb the voice recognition function.

Control status is displayed on Forest ir Info screen. Refer to HC-45, "FOREST IR SYSTEM : Switch Name and Function". Sensitivity of exhaust gas / outside odor detecting sensor can be changed by Outside/Inside ir Mix in Forest ir Setting menu. Refer to HC-48, "FOREST IR SYSTEM : Menu Displayed by Pressing Each Switch". utomatic intake control (exhaust gas / outside odor detecting mechanism) does not operate when ambient temperature is 2 C (28 F) or less. In this case, control is only for control of automatic air inlet of automatic air conditioning system. FOREST IR SYSTEM : reezy ir Control INFOID: DESCRIPTION ir conditioning air flow similar to the air flow of a natural breeze is achieved through the random control of air flow switching timing from the upper ventilator and center ventilator. OPERTION DESCRIPTION This control automatically operates when FOREST switch is ON, air outlet mode is VENT or FOOT, and passenger room temperature is in stable status. Control status is displayed on Forest ir Info screen. Refer to HC-45, "FOREST IR SYSTEM : Switch Name and Function". ON/OFF of breezy air control can be changed by reeze Mode in Forest ir Setting menu. Level of breezy air can be selected by Fan Speed Variance in Forest ir Setting menu.
