(5 N.m.). 2) Brush the valve (1) with soapy water and install the valve on the rim (see Figure 4). CAUTION: Do not use tools within the marked area (see Figure 2). CAUTION: Always start outside the marked area and continue in the direction from the valve. 3) Fit the tire and balance the wheel. 4) Install the wheel. 5) Afer replacing sensors, the control module does not need programming.
