PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612901
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 ICC System ServiceINFOID:0000000001328803
 Never look straight into the laser beam discharger when adjusting laser beam aiming.
 Turn the MAIN switch OFF in conditions similar to dr iving, such as free rollers or a chassis dynamometer.
 Do not use the ICC sensor removing from v ehicle, disassemble, or remodel the sensor.
 Erase DTC when replacing parts of ICC system, then c heck the operation of ICC system after adjusting laser
beam aiming if necessary.

A/T FLUID
When wiping away the A/T fluid level gauge, always use lint-free paper, not a cloth one.
e. Re-insert A/T fluid level gauge into A/T fluid charging pipe as far as it will go. CAUTION:
To check A/T fluid level, insert the A/T fluid level gauge until the cap contacts the end of the A/T
fluid charging pipe, with the A/ T fluid level gauge reversed from the normal attachment conditions.
f. Remove A/T fluid level gauge and note reading. If reading is at low side of range, add ATF to the A/T fluid
charging pipe.
CAUTION:
Do not overfill.
5. Drive vehicle for approximately 5 minutes in urban areas.
6. Make the A/T fluid temperature approximately 65 °C (149 °F).
NOTE:
A/T fluid level will be greatly affected by temper ature as shown in figure. Therefore, be certain to
perform operation while checki ng data with CONSULT-III.
a. Connect CONSULT-III to data link connector.
b. Select “MAIN SIGNALS” in “DATA MONITO R” mode for “TRANSMISSION” with CONSULT-III.
c. Read out the value of “ATF TEMP 1”.
7. Recheck A/T fluid level at A/T fluid temperatures of approximately 65 °C (149 °F) using “HOT” range on A/
T fluid level gauge.
CAUTION:
 When wiping away the A/T fluid level gauge, always use lint-free paper, not a cloth one.
 To check A/T fluid level, inser t the A/T fluid level gauge
until the cap contacts the en d of the A/T fluid charging
pipe, with the A/T fluid level gauge reversed from the nor-
mal attachment conditions as shown.
8. Check A/T fluid condition.  If ATF is very dark or smells burned, check operation of A/T.
Flush cooling system after repair of A/T.
 If ATF contains frictional material (clutches, bands, etc.), replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer to CO-13
(for
VQ35DE) or CO-40
(for VK45DE) and AT-13, "A/T Fluid
Cooler Cleaning".
