Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951582
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 NISS AN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses 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 electri c 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.
General precautions fo r service operationsINFOID:0000000009463538
• Do not work with wet hands.
• The xenon headlamp system includes a high voltage generating
part. Be sure to disconnect batte ry negative cable (negative termi-
nal) or power fuse before removing, installing, or touching the
xenon headlamp (including lamp bulb).
• Turn the lighting switch OFF before disconnecting and connecting the connector.
• When turning the xenon headlamp on and while it is illuminated, do
not touch the harness, bulb, and socket of the headlamp.
• When checking the headlamp on/off operation, check it on vehicle and with the power connected to the vehicle-side connector.
• Do not touch the headlamp bulb glass surface with bare hands or allow oil or grease to get on it. Do not touch the headl amp bulb just after the headlamp is turned off, because
it is very hot.
• Install the xenon headlamp bulb socket co rrectly. If it is installed improperly, high-voltage leak or corona dis-
charge may occur that can melt the bulb, connector or housing. Do not illuminate the xenon headlamp bulb
out of the headlamp housing. Doing so can cause fire and harm your eyes.
• When the bulb has burned out, wrap it in a thick vinyl bag and discard. Do not break the bulb.
• Leaving the bulb removed from the headlamp housing for a long period of time can deteriorate the perfor- mance of the lens and reflector (dirt, clouding). Al ways prepare a new bulb and have it on hand when replac-
ing the bulb.
• When adjusting the headlamp aiming, turn the aiming adjus tment screw only in the tightening direction. If it
is necessary to loosen the screw, first fully loosen the screw, and then turn it in the tightening direction.
• Do not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant.
