PRECAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
ACS003KX
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 for TCM and CVT Assembly Replacement
ACS001SA
CAUTION:
●
Check if new data (Unit ID) are entered correctly after replacing CVT assembly and erasing data in
TCM. (Connect CONSULT-II, and then turn ignition switch OFF.)
●
When replacing CVT assembly or TCM, refer to the pattern table below and erase the EEPROM in the
TCM if necessary.

CAUTION:
●
Securely align
∆
marking on CVT unit harness connector
terminal body with bayonet ring slit. Then, be careful not
to make a half fit condition as shown in the figure.

Changing CVT Fluid
ACS002KX
1.
Warm up CVT fluid by driving the vehicle for 10 minutes.
2.
Drain CVT fluid from CVT fluid cooler hose (return side) and refill with new CVT fluid at CVT fluid charging
pipe with the engine running at idle speed.
3.
Refill until new CVT fluid comes out from CVT fluid cooler hose (return side).
About 30 to 50% extra fluid will be required for this procedure.
CAUTION:
●
Use only Genuine NISSAN CVT fluid NS-2. Do not mix with other fluid.
●
Using CVT fluid other than Genuine NISSAN CVT fluid NS-2 will deteriorate in driveability and
CVT durability, and may damage the CVT, which is not covered by the warranty.
●
When filling CVT fluid, take care not to scatter heat generating parts such as exhaust.
●
Delete CVT fluid deterioration date with CONSULT-II after changing CVT fluid. Refer to
"Check CVT Fluid Deterioration Date"
4.
Check fluid level and condition.
CVT Fluid Cooler Cleaning
ACS004MD
Whenever an automatic transaxle is repaired, overhauled, or replaced, the CVT fluid cooler mounted in the
radiator must be inspected and cleaned.
Metal debris and friction material, if present, can become trapped in the CVT fluid cooler. This debris can con-
taminate the newly serviced CVT or, in severe cases, can block or restrict the flow of CVT fluid. In either case,
malfunction of the newly serviced CVT may result.
Debris, if present, may build up as CVT fluid enters the cooler inlet. It will be necessary to back flush the cooler
through the cooler outlet in order to flush out any built up debris.
CVT FLUID COOLER CLEANING PROCEDURE
1.
Position an oil pan under the transaxle's inlet and outlet cooler hoses.
2.
Identify the inlet and outlet fluid cooler hoses.
3.
Disconnect the fluid cooler inlet and outlet rubber hoses from the
steel cooler tubes or bypass valve.
NOTE:
Replace the cooler hoses if rubber material from the hose
remains on the tube fitting.
4.
Allow any CVT fluid that remains in the cooler hoses to drain into
the oil pan.

remaining fluid.
10. Repeat steps 5 through 9 three additional times.
11. Position an oil pan under the banjo bolts that connect the fluid
cooler steel lines to the transaxle.
12. Remove the banjo bolts.
13. Flush each steel line from the cooler side back toward the tran-
saxle by spraying Transmission Cooler Cleaner in a continuous stream for 5 seconds.
14. Blow compressed air regulated to 5 - 9 kg/cm
2
(70 - 130 psi) through each steel line from the cooler side
back toward the transaxle for 10 seconds to force out any remaining fluid.
15. Ensure all debris is removed from the steel cooler lines.
16. Ensure all debris is removed from the banjo bolts and fittings.

.
CVT FLUID COOLER INSPECTION PROCEDURE
1.
Inspect the coffee filter for debris.
a.
If small metal debris less than 1mm (0.040 in) in size or metal
powder is found in the coffee filter, this is normal. If normal
debris is found, the CVT fluid cooler/radiator can be re-used and
the procedure is ended.
b.
If one or more pieces of debris are found that are over 1 mm
(0.040 in) in size and/or peeled clutch facing material is found in
the coffee filter, the fluid cooler is not serviceable. The radiator/
fluid cooler must be replaced and the inspection procedure is
ended.
CVT FLUID COOLER FINAL INSPECTION
After performing all procedures, ensure that all remaining oil is cleaned from all components.
