  2. ROTATE TIRES


    1. A000T18E01
      Text in Illustration
      *a Front of the Vehicle
      *b When all tires are the same size
      *c When the size of the front and rear tires is not the same

      Rotate the tires as shown in the illustration.

      Torque:
      103 N*m  { 1050 kgf*cm, 76 ft.*lbf }

      Tech Tips

      When a tire rotation is performed on a vehicle that has different specified tire pressures for the front and rear of the vehicle, it is necessary to perform initialization for the tire pressure warning system Click here.

  3. INSPECT WHEEL BALANCE


    1. A000OBME01

      Check and adjust the off-the-car balance.

      Maximum imbalance after adjustment
      8.0 g (0.0176 lb.)

      Note


      • Use a cleaning detergent to remove dirt, oil and water from the surface where the balance weight is to be adhered.

      • Do not touch the sticking surface of the tape.

      • Adhere a sticking type balance weight to the flat surface (A) shown in the illustration.

        Width (A)
        25 mm (0.984 in.)
      • Push the balance weight firmly to adhere it to the position.

      • Do not reuse the balance weight.

      • Please use the LEXUS genuine sticking type balance weight.

      Tech Tips

      If necessary, check and adjust the on-the-car balance.
