CAUTION
1. SUPPLEMENTAL RESTRAINT SYSTEM “AIRBAG”
Airbag system wiring harness is routed near the TPM control module.
CAUTION:
• Do not use electrical test equipment on any of the airbag system wiring harness circuits.
• Be careful not to damage the wiring harness of the airbag system when servicing the TPMS & keyless entry CM or TPMS CM.
2. TPMS & KEYLESS ENTRY CM OR TPMS CM
• If the transmitter is replaced, ID registration for the transmitter is required. Register Transmitter (ID) > OPERATION">
• When adjusting tire pressure indoors in winter, there is a big temperature difference between the indoor facilities and outside. Once the car is outside where the temperature is lower, the air pressure in the tires will drop, causing the tire pressure warning light to illuminate, even if the pressure in the tires was adjusted to standard values indoors. To avoid this, it is necessary to adjust the tire pressure to the high side in consideration of the difference in temperature between inside and outside according to the following table.
• P195/65R15, P205/55R16, P225/55R17 (CVT)
