< PRECAUTION >
PRECAUTIONS
• ID registration is required when replacing or rotating wheels, replacing tire pressure sensor or BCM. Refer to
.
• For easy fill tire alert function, refer to the following.
- When inflating the tires, park the vehicle in the safe area and ensure the safety of the working area.
- Read and understand the easy fill tire alert function prior to use.
- Inflate the tires one at a time.
- If there is no response for approximately 15 seconds or more after inflating the tires, cancel the use of the
easy fill tire alert function or move the vehicle approximately 1 m (3.2 ft) backward or forward to try again.
The air filler pressure may be weak or out of service area.
- Despite the high-precision TPMS pressure sensor, an indicated value may differ from that of the pressure
gauge.
- Air pressure is measured rather high due to the rise in tire air temperature after driving.
- If TPMS is malfunctioning, the easy fill tire alert is unusable.
• Replace grommet seal, valve core and valve cap of tire pressure sensor in TPMS, when replacing each tire
by reaching the wear limit. Refer to
• Because the tire pressure sensor conforms to North America radio law, the following items must be
observed.
- The sensor may be used only in North America.
- It may not be used in any method other than the specified method.
- It must not be disassembled or modified.
Service Notice and Precautions for Road Wheel
INFOID:0000000009653411
• Genuine NISSAN aluminum wheel is designed for each type of vehicle. Use it on the specified vehicle only.
• Use Genuine NISSAN parts for the road wheels, valve caps and 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.
• When tightening the valve cap there is a risk of damaging the valve cap if a tool is used. Tighten by hand.

BCM
INFOID:0000000009653415
• The BCM reads the air pressure signal received by the tire pressure receiver, controls the low tire pressure
warning lamp, hazard warning lamp, and horn operation. It also has a judgment function to detect a system
malfunction.
• Controls easy fill tire alert function. Refer to

Tire Pressure Sensor
INFOID:0000000009653416
The tire pressure sensor integrated with a valve is installed on a wheel, and transmits a detected air pressure
signal by radio wave.
Tire Pressure Receiver
INFOID:0000000009653417
• Tire pressure receiver is incorporated into remote keyless entry receiver.
• The tire pressure receiver receives the air pressure signal transmitted by the tire pressure sensor in each
wheel.
Information Display
INFOID:0000000009653418
The vehicle information display is shown when a low tire pressure warning lamp signal is transmitted from
BCM to combination meter. via CAN communication.
