REMOVAL
Using releasing agent, remove double-faced adhesive tape from the road wheel.
CAUTION:
Be careful not to scratch the road wheel during removal.
After removing double-faced adhesive tape, wipe clean traces of releasing agent from the road
wheel.
WHEEL BALANCE ADJUSTMENT
If a tire balance machine has adhesion balance weight mode settings and drive-in weight mode setting,
select and adjust a drive-in weight mode suitable for road wheels.
1. Set road wheel on tire balance machine using the center hole as a guide. Start the tire balance machine.
2. When inner and outer unbalance values are shown on the tire balance machine indicator, multiply outer unbalance value by 5/3 to determine balance weight that should be used. Select the outer balance weight
with a value closest to the calculated value above and install it to the designated outer position of, or at the
designated angle in relation to the road wheel.
CAUTION:
Do not install the inner balance weight before installing the outer balance weight.
Before installing the balance weight, be sure to clean the mating surface of the road wheel.
a. Indicated unbalance value × 5/3 = balance weight to be installed
Calculation example:
23 g (0.81 oz) × 5/3 = 38.33 g (1.35 oz) 37.5 g (1.32 oz) bal-
ance weight (closer to calculated balance weight value)
NOTE:
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
36.2 35 g (1.23 oz)
36.3 37.5 g (1.32 oz)
b. Install balance weight in the position shown in the figure.
c. When installing balance weight to road wheels, set it into the grooved area on the inner wall of the road wheel as shown in the
figure so that the balance weight center is aligned with the tire
balance machine indication position (angle).
CAUTION:
Always use genuine NISSAN adhesion balance weights.
Balance weights are non-reusable; always replace with
new ones.
Do not install more than three sheets of balance weight.

d. If calculated balance weight value exceeds 50 g (1.76 oz), install
two balance weight sheets in line with each other as shown in
the figure.
CAUTION:
Do not install one balance weight sheet on top of another.
3. Start tire balance machine again.
4. Install drive-in balance weight on inner side of road wheel in the tire balance machine indication position (angle).
CAUTION:
Do not install more than two balance weights.
5. Start tire balance machine. Make sure that inner and outer resid- ual unbalance values are 5 g (0.2 oz) each or below.
6. If either residual unbalance value exceeds 5 g (0.2 oz), repeat installation procedures.
Tire RotationNES000KZ
1. Follow the maintenance schedule for tire rotation service intervals. Refer to MA-7, "Introduction of Peri-
odic Maintenance" .
2. Do not include the spare tire when rotating the tires.
3. When installing the wheel, tighten wheel nuts to the specified torque.
CAUTION:
When installing wheels, tighten them diagonally by dividing the work two to three times in order
to prevent the wheels from developing any distortion.
Be careful not to tighten wheel nut at torque exceeding the criteria for preventing strain of disc
rotor.
4. Perform the ID registration, after tire rotation. Refer to WT-20, "
ID Registration Procedure" .

TIRE PRESSURE MONITORING SYSTEMPFP:40720
System ComponentsNES000GP
System DescriptionNES000GQ
TRANSMITTER
A sensor-transmitter integrated with a valve is installed on a wheel,
and transmits a detected air pressure signal in the form of a radio
wave.
REMOTE KEYLESS ENTRY RECEIVER
The remote keyless entry receiver receives the air pressure signal
transmitted by the transmitter in each wheel.

TIRE PRESSURE MONITORING SYSTEM
Revision: 2006 July 2007 FX35/FX45
BCM (BODY CONTROL MODULE)
The BCM reads the air pressure signal received by the remote key-
less entry receiver, and controls the low tire pressure warning lamp
and the buzzer operations. It also has a judgment function to detect
a system malfunction.
LOW TIRE PRESSURE WARNING LAMP
The combination meter receives tire pressure status from the BCM
using CAN communication. When a low tire pressure condition is
sensed by the BCM, the combination meter low tire pressure warn-
ing lamp is activated.
Low Tire pressure Warning Lamp Indication
Note 1: Standard air pressure is for 220 kpa (2.2 kg/cm2 , 32 psi) vehicles.
RUN-FLAT TIRE WARNING LAMP
The combination meter receives tire pressure status from the BCM
using CAN communication. When a low tire pressure condition is
sensed by the BCM, the combination meter run-frat tire warning
lamp and buzzer are activated.

CAN COMMUNICATION
Revision: 2006 July 2007 FX35/FX45
CAN COMMUNICATIONPFP:23710
System DescriptionNES000GR
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
Refer to LAN-49, "
CAN System Specification Chart" .
