IN CASE OF AN EMERGENCY D Have the wheel nuts tightened with torque wrench to 103 N·m (10.5 kgf·m, 76 ft·lbf.), as soon as possible after changing wheels. Otherwise, the nuts may loosen and the wheels may fall off, which could cause a serious accident. 10. After changing the wheel, check the air pressure of the replaced tire. Stow all the tools, jack and flat tire securely. 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 the order shown. Repeat the process until all the nuts are tight. 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 possibly cause air leakage. If the cap is missing, put a new one on as soon as possible. This is the same procedure for changing or rotating your tires. 40L167 CAUTION D When lowering the vehicle, make sure all portions of your body and all other persons around will not be injured as the vehicle is lowered to the ground. 409
