IN CASE OF AN EMERGENCY 9. Lower the vehicle completely and tighten the wheel nuts. Turn the jack handle counterclockwise to lower the vehicle. Use only the wheel nut wrench to tighten the nuts. Do not use other tools or any additional leverage other than your hands, such as a hammer, pipe or your foot. Make sure the wrench is securely engaged over the nut. Tighten each nut a little at a time in order shown. Repeat the process until all the nuts are tight. 10. Reinstall the wheel ornament. Put the wheel ornament into position and then tap it firmly with the side or heel of your hand to snap it into place. ! CAUTION Take due care in handling the ornament to avoid unexpected personal injury. 11. After changing the wheel, check the air pressure of the replaced tire. Stow all the tools, jack and flat tire securely. If the pressure of the replaced tire is low, drive slowly to the nearest service station and fill to the correct pressure. Do not forget to reinstall the tire valve cap as dirt and moisture could get into the valve core and possible cause air leakage. If the cap is missing, put a new one on as soon as possible. 173 ! CAUTION As soon as possible after changing wheels, have the wheel nuts tightened by torque wrench at 103 N·m (10.5 kgf·m, 76 ft·lbf).
