PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612925
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. 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 “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
 To avoid rendering the SRS inoper ative, 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 NISSAN/INFINITI dealer.
 Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
Precaution for On Board Diagnosis (OBD) System of A/T and EngineINFOID:0000000001327123
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:
 Be sure to turn the ignition sw itch OFF and disconnect the battery cable from the negative terminal
before any repair or inspection work. The open/s hort circuit of related switches, sensors, solenoid
valves, etc. Will cause the MIL to light up.
 Be sure to connect and lock the connectors secure ly after work. A loose (unlocked) connector will
cause the MIL to light up due to an open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
 Be sure to route and secure the harnesses properly after work. Interference of the harness with a
bracket, etc. May cause the MIL to li ght up due to a short circuit.
 Be sure to connect rubber tubes properly afte r work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to a malfunction of the EVAP system or fuel injection system, etc.
 Be sure to erase the unnecessary malfunction informa tion (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
PrecautionINFOID:0000000001327124
 Before connecting or disco nnecting the A/T assembly har-
ness connector, turn ignition switch OFF and disconnect the
battery cable from the negative terminal. Because battery
voltage is applied to TCM even if ignition switch is turned
OFF.

Precaution Necessary for Steering Wh eel Rotation After Battery Disconnect
INFOID:0000000001612931
NOTE:
 This Procedure is applied only to models with Intell igent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).
 Remove and install all control units after disconnecti ng both battery cables with the ignition knob in the
″ LOCK ″ position.
 Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NVIS/IVIS, an electrically controlled steering lock
mechanism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery pow er is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables. NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC ″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-III.

Precaution for Working with HFC-134a (R-134a)INFOID:0000000001328153
CAUTION:
 CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refr igerant are not compatible. If the refrigerants
are mixed and compressor malfunct ion is likely to occur, refer to “CONTAMINATED REFRIGERANT”
below. To determine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use Refriger-
ant Recovery/Recycling Rech arging equipment and Refrigerant Identifier.
 Use only specified lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) compo-
nents. If lubricant other than that specified is used, compressor malfunction is likely to occur.
 The specified HFC-134a (R-134a) lu bricant rapidly absorbs moisture from the atmosphere. The fol-
lowing handling precauti ons must be observed:
- When removing refrigerant components from a vehicle, immediately cap (seal) the component to
minimize the entry of moisture from the atmosphere.
- When installing refrigerant components to a vehic le, never remove the caps (unseal) until just before
connecting the components. Connect all refriger ant loop components as quickly as possible to min-
imize the entry of moisture into system.
- Only use the specified lubricant fr om a sealed container. Immediately reseal containers of lubricant.
Without proper sealing, lubrican t will become moisture saturated and should not be used.
- Never allow lubricant (Nissan A/C System Oil Type S) to come in contact with styrene foam parts.
Damage may result.
CONTAMINATED REFRIGERANT
If a refrigerant other than pure HFC-134a (R-134a) is identified in a vehicle, take appropriate steps
shown below:
 Explain to the customer that environmental regulations prohibit the release of contaminated refrigerant into
the atmosphere.
 Explain that recovery of the contaminated refri gerant could damage service equipment and refrigerant sup-
ply.
 Suggest the customer return the vehicle to the locati on of previous service where the contamination may
have occurred.
 In case of repairing, recover the refrigerant using only dedicated equipment and containers. Never
recover contaminated refrigerant into the existing service equipment. If the facility does not have ded-
icated recovery equipment, contact a local refrigerant pr oduct retailer for available service. This refrigerant
must be disposed of in accordance with all federal and local regulations. In addition, replacement of all
refrigerant system components on the vehicle is recommended.
 If the vehicle is within the warranty period, the air conditioner warranty is void. Please contact Nissan Cus-
tomer Affairs for further assistance.
General Refrigerant PrecautionINFOID:0000000001328154
WARNING:
 Avoid breathing A/C refrigerant and lubricant vap or or mist. Exposure may irritate eyes, nose and
throat. Remove HFC-134a (R-134a) from the A/C syst em, using certified service equipment meeting
requirements of SAE J-2210 [HFC-134a (R-134a) recycling equipment], or J-2209 [HFC-134a (R-134a)
recovery equipment]. If accidental system discharge occurs, ventilate work area before resuming
service. Additional health and saf ety information may be obtained from refrigerant and lubricant
manufacturers.
