PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NJS000FN
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 Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions Necessary for Steering Wheel Rotation After Battery DisconnectNJS000FO
NOTE:

This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).

Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK″ position.

Always use CONSULT-II 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 power 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-II.

2. Slide disconnector in axial direction of piping, and stretch garter spring with tapered point of disconnector.
3. Slide disconnector farther so that inside diameter of garter spring becomes larger than outside diameter of
female-side piping flare. Then male-side piping can be disconnected.
INSTALLATION
1. Clean piping connection points, and insert male-side piping into female-side piping.
2. Push inserted male-side piping harder so that female-side piping flare stretches garter spring.
3. If inside diameter of garter spring becomes larger than outside diameter of female-side piping flare, garter
spring seats on flare. Then, it fits in between male-side piping cage and female-side piping flare to anchor
piping connection point.
NOTE:
When garter spring seats on flare, and fits in between male-side piping cage and female-side piping flare,
it clicks.
CAUTION:

Female-side piping connection is thin and easy to deform. Slowly insert the male-side piping
straight in axial direction.

Insert piping securely until a click is heard.

After piping connection is completed, pull male-side piping by hand to make sure that connec-
tion does not come loose.
NOTE:
One-touch joint connection is used in points below.

Low-pressure flexible hose to low-pressure pipe 1 (O-ring size: 16)

High-pressure flexible hose to condenser (O-ring size: 12)

High-pressure pipe 1 to high-pressure pipe 2 (O-ring size: 8)

PRECAUTIONS
Revision: 2007 April2007 M35/M45
WARNING:
Make sure all refrigerant is discharged into the recycling equipment and the pressure in the system is
less than atmospheric pressure. Then gradually loosen the discharge side hose fitting and remove it.
CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.

When the compressor is removed, store it in the same way at it is when mounted on the car. Fail-
ure to do so will cause lubricant to enter the low-pressure chamber.

When connecting tubes, always use a torque wrench and a back-up wrench.

After disconnecting tubes, immediately plug all openings to prevent entry of dust and moisture.

When installing an air conditioner in the vehicle, connect the pipes at the final stage of the opera-
tion. Never remove the seal caps of pipes and other components until just before required for con-
nection.

Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.

Thoroughly remove moisture from the refrigeration system before charging the refrigerant.

Always replace used O-rings.

When connecting tubes, apply lubricant to circle of the O-rings shown in illustration. Be careful
not to apply lubricant to threaded portion.

O-ring must be closely attached to the groove of tube.

When replacing the O-ring, be careful not to damage O-ring and tube.

Connect tube until a click can be heard, then tighten the nut or bolt by hand. Make sure that the O-
ring is installed to tube correctly.

After connecting line, perform leak test and make sure that there is no leakage from connections.
When the refrigerant leaking point is found, disconnect that line and replace the O-ring. Then
tighten connections of seal seat to the specified torque.
Precautions for Servicing CompressorNJS000FT

Plug all openings to prevent moisture and foreign matter from entering.

When the compressor is removed, store it in the same way at it is when mounted on the car.

When replacing or repairing compressor, follow “Maintenance of Lubricant Quantity in Compres-
sor” exactly. Refer to AT C - 2 6 , "
Maintenance of Lubricant Quantity in Compressor" .

Keep friction surfaces between clutch and pulley clean. If the surface is contaminated with lubri-
cant, wipe it off by using a clean waste cloth moistened with thinner.Name : Nissan A/C System Oil Type S

AIR CONDITIONER CONTROL
Revision: 2007 April2007 M35/M45
REAR TEMPERATURE CONTROL SWITCH

Increases or decreases the set temperature.

A temperature for the rear seat with respect to a set temperature for the front seat can be adjusted by
operating switch.

Rear temperature control switch allows to select a temperature every 0.5°C (1°F) in the 18°C (60°F) to
32°C (90°F) range.

When the DUAL switch is ON, temperature for the rear seat changes keeping the temperature difference
between two front seats. [e.g. When lowering the set temperature for the rear seat 1°C (2°F) by operating
rear control switch at a set temperature of 25°C (77°F) for the driver’s seat and 26°C (79°F) for the pas-
senger’s seat, the set temperature for the driver’s seat and passenger’s seat lower 1°C (2°F) and become
24°C (75°F) for the driver’s seat and 25°C (77°F) for the passenger’s seat.]
NOTE:
A set temperature for the rear seat is tied to a set temperature for the passenger’s seat. Therefore, a set
temperature for the rear seat changes in conjunction with a set temperature for the passenger’s seat
(When the set temperature of front seats are independent).
Fail-Safe FunctionNJS000G9

control unit and multifunction switch for 30 seconds or longer, air conditioner is controlled under the follow-
ing conditions:
