ROAD WHEEL TIRE ASSEMBLY
Balancing Wheels INFOID:0000000004307317
Adjust wheel balance using road wheel center.
CAUTION:
• Be careful not to scratch th e road wheel during removal.
• Use clip-on type wheel balance weights only.
Wheel balance (Maximum allowable unbalance):
Rotation INFOID:0000000004307318
• Follow the maintenance schedule for tire rotation service intervals. Refer to MA-9 .
• Do not include the T-type spare tire when rotating tires. CAUTION:
• When installing wheels, tighte n 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 wh eel nut at torque exceeding the
specification to prevent damage of disc rotor.
Maximum allowable unbalance
Dynamic (At rim flange) Less than 5 g (0.18 oz) (one side)
Static (At rim flange) Less than 10 g (0.35 oz) Wheel nut : 113 N·m (12 kg-m, 83 ft-lb)

A sensor-transmitter integrated with a valve is installed in each
wheel, and transmits a detected air pressure signal in the form of a
radio wave. The radio signal is received by the remote keyless entry
receiver.
REMOTE KEYLESS ENTRY RECEIVER The remote keyless entry receiver is shown with the glove box
removed. The remote keyless entry receiver receives the air pres-
sure signal transmitted by the transmitter in each wheel.
COMBINATION METER 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.
TIRE PRESSURE WARNING CHECK CONNECTOR The tire pressure warning check connector can be grounded in order to initiate self-diagnosis without a CON-
SULT-III. Refer to WT-17, " Self-Diagnosis (Without CONSULT-III) " . The tire pressure warning check connector
is located behind the lower portion of the instrument panel LH. Refer to PG-38, " Harness Layout " . WEIA0186E

Transmitter Wake Up Operation INFOID:0000000004307325
NOTE:
This procedure must be done after replacement of a low tire pressure warning transmitter or BCM.
New replacement transmitters are provided "asleep" and must first be "woken up" using Transmitter
Activation Tool J-45295 before ID registration can be performed.
1. Turn ignition switch ON. Push the transmitter activation tool against the tire near the front left transmitter. Press the button for
5 seconds. The hazard warning lamps flash per the diagram
below.
2. Repeat this procedure for each tire in the following order: FL, FR, RR, RL.
3. When the BCM finishes assigning each tire ID, the BCM flashes the hazard warning lamps and sends flashing indicator status by CAN according to the following time chart.
4. After completing wake up of all transmitters, make sure low tire pressure warning lamp goes out.
