9-6 In case of emergency CAUTION Never use any temporary spare tire other than the original. Using other sizes may result in severe mechanical damage to the drive train of your vehicle. The temporary spare tire is smaller and lighter than a conventional tire and is designed for emergency use only. Remove the temporary spare tire and reinstall the conventional tire as soon as possible because the spare tire is designed only for temporary use. Check the inflation pressure of the temporary spare tire periodically to keep the tire ready for use. The correct pressure is 60 psi (420 kPa, 4.2 kgf/cm2). When using the temporary spare tire, note the following. . Do not exceed 50 mph (80 km/h). . Do not put a tire chain on the temporary spare tire. Because of the smaller tire size, a tire chain will not fit properly. . Do not use two or more temporary spare tires at the same time. . Do not drive over obstacles. This tire has a smaller diameter, so road clearance is reduced. Flat tires If you have a flat tire while driving, never brake suddenly; keep driving straight ahead while gradually reducing speed. Then slowly pull off the road to a safe place. & Changing a flat tire WARNING 1) 2) Tread wear indicator bar Indicator location mark . When the wear indicator appears on the tread, replace the tire. . The temporary spare tire must be used only on a rear wheel. If a front wheel tire gets punctured, replace the wheel with a rear wheel and install the temporary spare tire in place of the removed rear wheel. . Do not jack up the vehicle on an incline or a loose road surface. The jack can come out of the jacking point or sink into the ground and this can result in a severe accident. . Use only the jack provided with your vehicle. The jack supplied with the vehicle is designed only for changing a tire. That no person should place any portion of their body under a vehicle that is supported by a jack.
