PRECAUTIONS

PRECAUTIONS
PFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EKS009JA
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT 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 and SB section of this Service Man-
ual.
WARNING:
●
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 per-
formed by an authorized NISSAN/INFINITI dealer.
●
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 SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Instruction. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
General precautions for service operations
EKS009JB
●
Never work with wet hands.
●
Turn the lighting switch OFF before disconnecting and connecting the connector.
●
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 headlamp bulb just after the headlamp is turned off, because it is very hot.
●
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). Always prepare a new bulb and have it on hand when
replacing the bulb.
●
Do not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant.
Wiring Diagrams and Trouble Diagnosis
EKS009JC
When you read wiring diagrams, refer to the following:
●
Refer to
GI-15, "How to Read Wiring Diagrams"
in GI section.
●
Refer to
PG-4, "POWER SUPPLY ROUTING CIRCUIT"
for power distribution in PG section.
When you perform trouble diagnosis, refer to the following:
●
Refer to
GI-11, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES"
in GI section.
●
Refer to
GI-27, "How to Perform Efficient Diagnosis for an Electrical Incident"
in GI section.
