IN CASE OF AN EMERGENCY 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. 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. 9. After changing the wheel, check the air pressure of the replaced tire. Stow all the tools, jack and flat tire securely. If the inflation 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. CAUTION D When reinstalling a standard tire, take due care in handling the ornament to avoid unexpected personal injury. D Before driving, make sure all the tools, jack and flat tire are securely in place in their storage location to reduce the possibility of personal injury during a collision or sudden braking. 231
