WHEEL AND TIRE SYSTEM
PRECAUTION
1. REMOVAL AND INSTALLATION OF TIRE PRESSURE MONITOR VALVE SUB±ASSY
(a) When installing a tire, make sure that the tire pressure monitor valve does not interfere with the tire
bead in order to prevent damage to the sensor.
(b) After completing the operation, remove the valve core to rapidly release air and check that the warning
light comes on. If not, the system may have a defect.
(c) If there is air leakage, tighten the nut with a force of 4.0 NVm (41 kgfVcm, 35 in.Vlbf) and push the valve
core 2 or 3 times to remove any dirt attached to the valve core.
If there is still air leakage, replace the grommet, the washer and the nut all together.
(d) When installing the tire pressure monitor valve, check whether the rim, grommet, washer and nut are
clean. Use a manufacturer±specified cap.
(e) When putting air into the tire, first install the tire pressure valve straight onto the stem of the tire pres-
sure monitor valve.
2. TIRE AND WHEEL REPLACEMENT OR TIRE ROTATION
(a) When replacing tires, be sure to check if the grommet of the tire valve is damaged. If so, replace the
grommet together with the washer and nut.
(b) When tires and wheels are replaced, make sure to register the transmitter ID.

REPLACEMENT
1. REMOVE FRONT TIRE
2. REMOVE REAR TIRE
3. REMOVE TIRE PRESSURE MONITOR VALVE
(a) Remove the valve core and cap, and release air from the
tire.
(b) After ensuring that air is sufficiently released, remove the
nut and washer that are used to fix the tire pressure moni-
tor valve sub±assy and drop the sensor inside the tire.
HINT:
Keep the removed cap, valve core, nut and washer.
(c) After dropping the tire pressure monitor valve sub±assy
into the tire, disengage the bead using the shoe of the tire
remover.
NOTICE:
Be careful not to damage the tire pressure monitor valve
because of interference between the sensor and tire bead.
(d) Remove the bead on the upper side.
(e) Take out the sensor from the tire and remove the bead on
the lower side.
(f) Remove the inner grommet from the tire pressure monitor
valve sub±assy.
HINT:
Check that there are no cracks or damage to the grommet. If
any damage is found, replace the grommet together with the
washer and nut.
4. INSTALL TIRE PRESSURE MONITOR VALVE
(a) Insert the tire pressure monitor valve into the valve instal-
lation hole. Insert from the inside of the rim so that the print
surface can be seen.
NOTICE:

Check that there is no visible deformation, damage or
other abnormalities on the transmitter.

Check that there is no foreign matter on the inner
grommet and around the rim hole.

If installed in the reverse direction, the tire pressure
monitor valve may be damaged or fail to transmit sig-
nals when running at high speed.

If installing a new tire pressure monitor valve, write
down the ID number before installation.

It is necessary to registor an ID in the ECU after instal-
lation (See page DI±805).
(b) Install the washer on the tire pressure monitor valve from
the rim side and tighten with a nut.
Torque: 4.0 NVm (41 kgfVcm, 35 in.Vlbf)
NOTICE:

Check that there is no foreign matter on the washer
and nut.

If the tire pressure monitor valve is removed when the
tire is removed for replacement, check that there is no
damage or cuts, and no foreign matter such as mud,
dirt or sand attached to the grommet. Replace the
grommet with a new one if any of the defects men-
tioned above are found.

Check that there is no oil, water or lubricant around
the rim hole, tire pressure monitor valve, washer and
nut. Failing to do so may result in improper installa-
tion.
(c) After the tire is inflated, the valve nut may be loose. Re-
tighten the nut to the specified torque and then check for
air leaks with soapy water.
Torque: 4.0 NVm (41 kgfVcm, 35 in.Vlbf)
(d) Set the wheel disc to the mounting machine and install the
lower tire bead. Position the main body of the sensor as
in the shaded area shown in the illustration.
NOTICE:
If the sensor is positioned outside this area, it generates in-
terference with the tire bead, causing possible damage to
the sensor.
(e) Install the upper bead.
NOTICE:
Make sure that the tire bead and tool do not interfere with
the main body of the sensor and that the sensor is not
clamped by the bead.
