NOTE:
  • This system requires initialization after changing tires or wheels, or after rotating the tires.
  • Be sure to adjust the tire pressure to the specified value before initialization.
  1. INITIALIZING THE TIRE PRESSURE WARNING SYSTEM 
    1. Check and adjust the tire pressure to the specified value.
      TIRE PRESSURE WARNING SYSTEM SPECIFICATION

      Tire Size Specified Value (Front) Specified Value (Rear)
      P205/55 R16 89H P215/50 ZR17 P215/50 R17 90H 220 kPa (2.2 kgf/cm2 , 31 psi) 220 kPa (2.2 kgf/cm2 , 31 psi)
      P205/55 R16 89H (4WD) 240 kPa (2.4 kgf/cm2 , 34 psi) 220 kPa (2.2 kgf/cm2 , 31 psi)
    2. With the vehicle stopped, turn the ignition switch to the ON position.
    3. Press and hold the tire pressure warning reset switch until the tire pressure warning lamp blinks 3 times at 1 second intervals.

      HINT:

      If the tire pressure warning lamp does not blink, perform the initialization again. (With the ignition switch off, perform the procedure above starting from step  b.)

    4. Drive the vehicle at 19 mph (30 km/h) or more, to complete initialization of the skid control ECU. (It takes more than one hour.)

      HINT:

      If the tire pressure warning lamp repeats a cycle of ON (0.5 sec.) and OFF (2.5 sec.) while the vehicle is being driven, initialization may have failed. If so, perform the initialization again. (Turn the ignition switch off and retry from step  a.)

    5. After initialization is completed, the skid control ECU monitors the tire pressure by using the wheel speed sensors.
    6. To verify that the system has been initialized, check the length of time the tire pressure warning lamp is on after turning the ignition switch to the ON position.
      • Not initialized: 4 sec.
      • Initialized: 3 sec.
RENDER: 1.0x
