Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003854497
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. Information necessary to service the system safely is included in the “SRS AIRBAG” and
“SEAT BELT” of this Service Manual.
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 performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIRBAG”.
 Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.
Precaution Necessary for Steering Wheel Rotation after Battery Disconnect
INFOID:0000000003854498
NOTE:
 Before removing and installing any control units, first turn the push-button ignition switch to the LOCK posi-
tion, then disconnect both battery cables.
 After finishing work, confirm that all control unit connectors are connected properly, then re-connect both
battery cables.
 Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.
This vehicle is equipped with a push-button ignition switch and a steering lock unit.
If the battery is disconnected or discharged, the steering wheel will lock and cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, 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. Turn the push-button ignition switch to ACC position.
(At this time, the steering lock will be released.)
3. Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.
4. Perform the necessary repair operation.
5. When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button ignition switch is turned to LOCK position.)
6. Perform self-diagnosis check of all control units using CONSULT-III.

Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers do
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharge and contamination may
occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied lubricants have been used with the scale. The hose fitting must
be 1/2″-16 ACME if the scale controls refrigerant flow electronically.
CHARGING CYLINDER
Use of a charging cylinder is not recommended. Refrigerant may be vented into the air from the top valve of
the cylinder when filling the cylinder with refrigerant. Also, the accuracy of the cylinder is generally less than
that of an electronic scale or of quality recycle/recharge equipment.

WITH INTELLIGENT AIR CONDITIONER SYSTEM : Temperature Setting Trimmer
INFOID:0000000003888718
DESCRIPTION
If the temperature felt by the customer is different than the air flow temperature controlled by the temperature
setting, the A/C auto amp. control temperature can be adjusted to compensate for the temperature setting.
HOW TO SET
Using CONSULT-III, perform “TEMP SET CORRECT” on “WORK SUPPORT” of HVAC.
NOTE:
 When the temperature setting is set to 25.0°C (77°F) and −3.0°C (−6°F), the temperature controlled by A/C
auto amp. is 25.0°C (77°F) −3.0°C (6°F) = 22.0°C (71°F) and the temperature becomes lower than the tem-
perature setting.
 When the battery cable is disconnected from the negative terminal or when the battery voltage becomes 10
V or less, trimmer operation is canceled. Temperature set becomes that of initial condition.

AUTOMATIC AIR CONDITIONER SYSTEM
CLEAN Switch
 When the blower motor is operated, the indicator lamp of the clean switch illuminates by pressing the clean
switch. The air inlets are fixed to recirculation for approximately 5 minutes. After approximately 5 minutes
have passed, they change to the automatic re-circulation control system. The Plasmacluster ion generation
function operates for approximately 30 minutes (Blower motor operate) in clean mode after the clean switch
is ON. After approximately 30 minutes have passed, the vehicle is driven between ion control mode (approx-
imately 15 minutes) and clean mode (approximately 30 minutes) alternately.
NOTE:
When the clean switch is not ON
 Ignition switch: OFF
 Blower motor: OFF
 Mode position: Defroster (DEF)
 Ambient temperature: At about 0°C or below (Reactivate at about 2°C or above)
 When the gas sensor is malfunctioning
 The Plasmacluster ion generation function changes automatically to the ion control mode by turning the
clean switch OFF, and then operates for approximately 15 minutes. Then, it is operated between the clean
mode (approximately 15 minutes) and clean mode (approximately 15 minutes) alternately.
 When the clean switch is ON, the A/C switch is also turned ON in synchronization with the clean switch.
NOTE:
The A/C switch becomes deactivate and the clean switch is turned OFF in synchronization with the A/C
switch by the clean switch interlocking movement change function.
 Press the intake switch or defroster (DEF) switch when releasing the automatic recirculation control system.
A/C Switch
Compressor turns ON or OFF with this switch.
(Pressing the A/C switch when the A/C switch is ON turns OFF the A/C switch and compressor.)
Fan Control Dial
The blower speed is manually controlled with this dial. Seven speeds are available for manual control (as
shown on the display screen).
OFF Switch
Compressor and blower turn OFF, intake door and the mode doors are automatically controlled.
Rear Window Defogger Switch
When indicator is ON, rear window is defogged.
Intake Switch
 When the intake switch is ON, the intake switch indicator is turned ON, and air inlet is set to REC.
 When the intake switch is pressed again, the intake switch indicator is turned OFF, and air inlet is set to FRE.
 When the intake switch indicator is turned OFF, shifting mode position to DEF, intake switch is automatically
turned OFF (set to FRE mode). REC mode can be re-entered by pressing intake switch again.
DUAL Switch
 When the DUAL switch indicator is ON, the driver side and passenger side, temperature can each be set
independently.
 When the DUAL switch indicator is OFF, the driver side setting temperature is applied to both sides.
