PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NES000LO
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 Battery ServiceNES000LP
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.
Service Notice or PrecautionsNES000LQ

Low tire pressure warning lamp flashes 1min., then turns ON when occurring any malfunction except low
tire pressure.
Delete the memory with CONSULT-III, or register the ID to turn low tire pressure warning lamp OFF. Refer
to WT-21, "
ID Registration Procedure" .

ID registration is required when replacing or rotating wheels. replacing transmitter or BCM. Refer to WT-
21, "ID Registration Procedure" .

Replace grommet seal, valve core and cap of the transmitter in TPMS every tire replacement by reaching
wear limit of tire.

ROAD WHEELPFP:40300
InspectionNES00017
ALUMINUM WHEEL
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If
deformed, remove wheel and check wheel runout.
a. Remove tire from aluminum wheel and mount on a tire balance
machine.
b. Set dial indicator as shown in the figure.
STEEL WHEEL
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If
deformed, remove wheel and check wheel runout.
a. Remove tire from steel wheel and mount wheel on a tire balance
machine.
b. Set two dial indicators as shown in the figure.
c. Set each dial indicator to 0.
d. Rotate wheel and check dial indicators at several points around
the circumference of the wheel.
e. Calculate runout at each point as shown below.
f. Select maximum positive runout value and the maximum nega-
tive value.
Add the two values to determine total runout.
In case a positive or negative value is not available, use the
maximum value (negative or positive) for total runout.
If the total runout value exceeds the limit, replace steel wheel.Wheel runout (Dial indicator value):
Refer to WT-39, "
SERVICE DATA AND SPECIFICA-
TIONS (SDS)" .SFA975B
Radial runout = (A+B)/2
Lateral runout = (C+D)/2
Wheel runout:
Refer to WT-39, "

5. Inflate all tires to proper pressure. Refer to WT-39, "SERVICE DATA AND SPECIFICATIONS (SDS)" .
Transmitter Wake Up OperationNES0001H
WITH ACTIVATION TOOL
1. With the activation tool (J-45295) pushed against the front-left
transmitter, press the button for 5 seconds.

When ignition switch ON, as the low tire pressure warning
lamp blinks per the follow diagram, the respective transmitter
then must be woken up.
2. Register the ID of wheel that warning lamp flashes. When wake up of registered wheel has been com-
pleted, turn signal lamp flashes two times.
3. After completing wake up of all transmitters, make sure low tire pressure warning lamp goes out.

If more than one wheel transmitter is NOT activated, the warning light blinking patterns for those wheels will combine. (Example: one
blink/OFF/three blinks = Rear LH and Rear RH transmitters are not activated.)Low tire pres-
