Jacking up the vehicle and removing the damaged tire

► Never get under the vehicle while it is WARNING

► Never get under the vehicle while it is supported only by the jack. If it is necessary to work under the vehicle, support it with safety stands.
► Use only the jack provided with your vehicle to lift the vehicle. Do not use the jack provided with your vehicle on other vehicles. The jack is designed for lifting only your vehicle during a tire change.
► Use the correct jack-up points. Never use any other part of the vehicle for jack support.
► Never jack up the vehicle more than necessary.
► Never use blocks on or under the jack.
► Do not start or run the engine while vehicle is on the jack, as it may cause the vehicle to move. This is especially true for vehicles with limited slip differentials.
► Do not allow passengers to stay in the vehicle while it is on the jack. Carefully read the caution label attached to the jack body and the following instructions.

1. Place the jack directly under the jack-up

1. Place the jack directly under the jack-up points as illustrated. The jack should be used on level firm ground.

Installing the spare tire

The full-size temporary use only spare tire

The full-size temporary use only spare tire (if so equipped) is designed for emergency use. (See specific instructions under the heading Wheels and tires in the 8. Maintenance and do-it-yourself section.)

1. Clean any mud or dirt from the surface between the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel nuts alternately and evenly in the sequence as illustrated (1 , 2 , 3 , 4 , 5 , 6 ) until they are tight.
4. Lower the vehicle slowly until the tire touches the ground. Then, with the wheel nut wrench, tighten the wheel nuts securely in the sequence as illustrated. Lower the vehicle completely.

► Incorrect wheel nuts or improperly tightened WARNING

► Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to become loose or come off. This could cause an accident.
► Do not use oil or grease on the wheel studs or nuts. This could cause the nuts to become loose.
► Retighten the wheel nuts when the vehicle has been driven for 600 miles (1,000 km) (also in cases of a flat tire, etc.).
► As soon as possible, tighten the wheel nuts to the specified torque with a torque wrench. Wheel nut tightening torque: 98 ft-lb (133 Nm) The wheel nuts must be kept tightened to specification at all times. It is recommended that wheel nuts be tightened to specifications at each lubrication interval.
► Adjust tire pressure to the COLD pressure. COLD pressure: After the vehicle has been parked for three hours or more or driven less than 1 mile (1.6 km). COLD tire pressures are shown on the Tire and Loading Information label affixed to the driver side center pillar. After adjusting tire pressure to the COLD tire pressure, the display of the tire pressure information may show higher pressure than the COLD tire pressure after the vehicle has been driven more than 1 mile (1.6 km). This is because the tire pressurizes as the tire temperature rises. This does not indicate a system malfunction.

Stowing the damaged tire and tools

1. Securely store the damaged tire, jack and tools in the storage area.
2. Close the cargo floor cover.
3. Replace the cargo floor board.
