PRECAUTIONS

Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”
Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELTPRE-TENSIONER” used along with a 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. The SRS system composition which is available to INFINITI I35 is as follows (The composition varies according to optional equipment.):
I For a frontal collision
The Supplemental Restraint System consists of driver air bag module (located in the center of the steer­ing wheel), front passenger air bag module (located on the instrument panel on passenger side), seat belt pre-tensioners, a diagnosis sensor unit, crash zone sensor, warning lamp, wiring harness and spiral cable.
I For a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of front seat), satellite sensor, diagnosis sensor unit (one of components of air bags for a frontal collision), wiring harness, warning lamp (one of components of air bags for a frontal collision).
Information necessary to service the system safely is included in the RS section of this Service Manual.
WARNING:
I 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 should be per­formed by an authorized INFINITI dealer.
I 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 RS section.
I 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 harness connec­tor (and by yellow harness protector or yellow insulation tape before the harness connectors).

CIRCUIT BREAKER (PTC THERMISTOR TYPE)
The PTC thermistor generates heat in response to current flow. The temperature (and resistance) of the thermistor element varies with current flow. Excessive current flow will cause the element’s temperature to rise. When the temperature reaches a specified level, the electrical resistance will rise sharply to control the circuit current. Reduced current flow will cause the element to cool. Resistance falls accordingly and normal circuit current flow is allowed to resume.

EXTERIOR LAMP BATTERY SAVER CONTROL
While the headlamp is turned ON by “2ND” of light switch, the 5 minute timer is activated when the ignition switch is turned from ON (or START) to OFF (ACC OFF). Continuity between terminals 21 and 22, and between terminals 59 and 60 of smart entrance control unit will be disturbed after 5 minutes, then the headlamps will be turned off. While the headlamp is turned ON by “AUTO” of light switch, the 5 minutes timer is activated when the igni­tion switch signal changes from ON (or START) to OFF (ACC OFF), and either one of LH or RH front door switch ON signal is input. The auto light delay off timer is activated as the following:
I When the door switch signal changes from ON to OFF while the timer is activated, the timer in operation
is discontinued and the 45 second timer is reset.
I When the door switch signal changes from OFF to ON while the timer is activated, the timer is discontin-
ued and the 45 second timer is reset.
I When the one of four door switch signals changes from OFF to ON while the timer is activated, the timer
is discontinued and the 5 minute timer is reset.
I When all the door switch ON signals are input while the timer is activated, the timer is discontinued and
the 45 second timer is reset.
Exterior lamp battery saver control mode and auto light delay off timer period can be changed by the function setting of CONSULT-II (EL-47). When the lighting switch is turned from OFF to 2ND after headlamps are turned to off by the battery saver control, ground is supplied

AUTO LIGHT OPERATION
The auto light control system has an optical sensor inside it that detects outside brightness. When lighting switch is in “AUTO” position, ground is supplied
I to smart entrance control unit terminal 23 I from lighting switch terminal 42.
When ignition switch is turn to “ON” or “START” position, outside brightness is darker than prescribed level. Ground is supplied
I to headlamp relay LH and RH terminals 2 I through smart entrance control unit terminals 21, 59 and 43, 64.
Then both headlamp relays and tail lamp relay are energized, headlamps (low or high) and tail lamps are illu­minate according to switch position. Auto light operation allows headlamps and tail lamps to go off when outside brightness is brighter than pre­scribed level.
NOTE: The delay time changes (maximum of 20 seconds) as the outside brightness changes.
For parking license and tail lamp auto operation, refer to “PARKING, LICENSE AND TAIL LAMPS”.
VEHICLE SECURITY SYSTEM
The vehicle security system will flash the low beams if the system is triggered. Refer to “VEHICLE SECURITY (THEFT WARNING) SYSTEM” (EL-327).
XENON HEADLAMP
Xenon type headlamp is adopted to the low beam headlamps. Xenon bulbs do not use a filament. Instead, they produce light when a high voltage current is passed between two tungsten electrodes through a mixture of xenon (an inert gas) and certain other metal halides. In addition to added lighting power, electronic control of the power supply gives the headlamps stable quality and tone color. Following are some of the many advantage of the xenon type headlamp.
I The light produced by the headlamps is white color approximating sunlight that is easy on the eyes. I Light output is nearly double that of halogen headlamps, affording increased area of illumination. I The light features a high relative spectral distribution at wavelengths to the human eye is most sensitive,
which means that even in the rain, more light is reflected back from the road surface toward the vehicle, for added visibility.
I Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.
