WT-4
< PRECAUTION >
PRECAUTIONS
Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the
ignition ON or engine running, never use air or electric 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.
Precautions for Removing of Battery Terminal
INFOID:0000000010069720
• When removing the 12V battery terminal, turn OFF the ignition
switch and wait at least 30 seconds.
NOTE:
ECU may be active for several tens of seconds after the ignition
switch is turned OFF. If the battery terminal is removed before ECU
stops, then a DTC detection error or ECU data corruption may
occur.
• For vehicles with the 2-batteries, be sure to connect the main bat-
tery and the sub battery before turning ON the ignition switch.
NOTE:
If the ignition switch is turned ON with any one of the terminals of
main battery and sub battery disconnected, then DTC may be
detected.
• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.
NOTE:
The removal of 12V battery may cause a DTC detection error.
Service Notice and Precautions for TPMS

• Low tire pressure warning lamp blinks for 1min, then turns ON when occurring any malfunction except low
tire pressure. Delete the memory with CONSULT, or register the ID to turn low tire pressure warning lamp
OFF. Refer to
WT-10, "AIR PRESSURE MONITOR : CONSULT Function (BCM - AIR PRESSURE MONI-
• ID registration is required when replacing or rotating wheels, replacing tire pressure sensor or BCM. Refer to
• Replace grommet seal, valve core and cap of tire pressure sensor in TPMS every tire replacement by reach-
ing wear limit of tire. Refer to
Service Notice and Precautions for Road Wheel
INFOID:0000000009722237
• Genuine NISSAN aluminum wheel is designed for each type of vehicle. Use it on the specified vehicle only.
• Use Genuine NISSAN parts for the wheel nuts.
• Always use them after adjusting the wheel balance. For the balance weights, use Genuine NISSAN alumi-
num wheel weights.
• Use caution when handling the aluminum wheels, because they can be easily scratched. When removing
dirt, do not use any abrasives, a wire brush, or other items that may scratch the coating. Use a neutral deter-
gent if a detergent is needed.
• After driving on roads scattered with anti-icing salts, wash off the wheels completely.
• When installing road wheels onto the vehicle, always wipe off any dirt or foreign substances to prevent them
from being trapped between the contact surfaces of wheel.
• Never apply oil to nut and bolt threads.
