PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER" INFOID:0000000004800720
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 w hether 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 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 SRS section.
• 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.
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric 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 3 minutes before performing any service.
Precaution Necessary for Steering Wh eel Rotation After Battery Disconnect
INFOID:0000000004305562
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 al l control units using CONSULT-III.

CAUTION:
Never start engine.
7. Select “Self Diagnostic Results” in “TRANSMISSION”.
8. Shift the selector lever to “R” position.
9. Depress slightly the accelerator pedal (Pedal angle: 2/8) while depressing the brake pedal.
10. Select “Erase”.
11. Turn ignition switch OFF while keeping the selector lever in “R” position.
12. Wait approximately 10 seconds.
13. Turn ignition switch ON while keeping the selector lever in “R” position. CAUTION:
Never start engine.
14. Select “Special function” in “TRANSMISSION”.
15. Check that the value on “CALIBRATION DATA” in CONS ULT-III is the same as the data listed in the table
below.
• Restart the procedure from step 3 if the values are not the same.
CALIBRATION DATA
16. Shift the selector lever to “P” position.
17. Check that the shift position indicator in combinat ion meter turns ON. (It indicates approximately 1 or 2
seconds after shifting the selector lever to “P” position.)
• Check the following items if shift position indicator does not turn ON. Repair or replace accordingly as necessary.
- The harness between TCM and ROM ASSY in transaxle assembly is open or shorted.
- Terminals disconnected, loose, or bent from connector housing.
- Power supply and ground of TCM. Refer to CVT-295, " Description " .
PATTERN C 1. Replace transaxle assembly first, and then replace TCM.
2. Perform the service of “PATTERN A”. (Perform the service of “PATTERN B” if TCM is replaced first.)

Checking CVT Fluid INFOID:0000000004305570
FLUID LEVEL CHECK
Fluid level should be checked with the fluid warmed up to 50 ° to 80 °C (122 ° to 176 °F).
1. Check for fluid leakage.
2. With the engine warmed up, drive the vehicle to warm up the CVT fluid. When ambient temperature is 20 °C (68 °F), it takes
about 10 minutes for the CVT fluid to warm up to 50 ° to 80 °C
(122 ° to 176 °F).
3. Park the vehicle on a level surface and set the parking brake.
4. With engine at idle, while depressing brake pedal, move the selector lever throughout the entire shift range and return it to
the “P” position.
5. Press the tab on the CVT fluid level gauge to release the lock and pull out the CVT fluid level gauge from the CVT fluid charg-
ing pipe.
6. Wipe fluid off the CVT fluid level gauge. Then rotate the CVT fluid level gauge 180 ° and re-insert it into the CVT charging pipe
as far as it will go.
CAUTION:
Always use lint free paper towels to wipe fluid off the CVT
fluid level gauge.
7. Remove the CVT fluid level gauge and check that the fluid level is within the specified range as shown. If the fluid level is at or
below the low side of the range, add the necessary specified
NISSAN CVT fluid through the CVT charging pipe.
CAUTION:
• Only use specified NISSAN CVT fluid.
• Do not overfill the CVT.
8. Install the CVT fluid level gauge to the CVT fluid charging pipe until it locks. CAUTION:
When CVT fluid level gauge is in stalled into the CVT fluid charging pipe, make sure that the CVT
fluid level gauge is securely locked in place. SMA146B
