Replacing a flat tire

1. Chock the tires.

2. Slightly loosen the wheel nuts (one turn).

The jack point guides are located under the rocker panel. They indicate the jack point positions.

4. Install the wheel nut wrench in jack handle.

When resting the tire on the ground, place the tire so that the wheel design faces up to avoid scratching the wheel surface.

WARNING

■Replacing a flat tire

• Observe the following precautions.

  Failure to do so may result in serious injury:

  • Do not try to remove the wheel ornament by hand. Take due care in handling the ornament to avoid unexpected personal injury.
  • Do not touch the disc wheels or the area around the brakes immediately after the vehicle has been driven.

    After the vehicle has been driven the disc wheels and the area around the brakes will be extremely hot. Touching these areas with hands, feet or other body parts while changing a tire, etc. may result in burns.

• Failure to follow these precautions could cause the wheel nuts to loosen and the tire to fall off, resulting in death or serious injury.
  • Never use oil or grease on the wheel bolts or wheel nuts.

    Oil and grease may cause the wheel nuts to be excessively tightened, leading to bolt or disc wheel damage. In addition, the oil or grease can cause the wheel nuts to loosen and the wheel may fall off, causing a serious accident.

    Remove any oil or grease from the wheel bolts or wheel nuts.

  • Have the wheel nuts tightened with a torque wrench to 76 ft*lbf (103 N*m, 10.5 kgf*m) as soon as possible after changing wheels.
  • When installing a tire, only use wheel nuts that have been specifically designed for that wheel.
  • If there are any cracks or deformations in the bolt screws, nut threads or bolt holes of the wheel, have the vehicle inspected by your Lexus dealer.
  • Do not attach a heavily damaged wheel ornament, as it may fly off the wheel while the vehicle is moving.

■Replacing a flat tire for vehicles with power back door In cases such as when replacing tires, make sure to turn off the power back door main switch. Failure to do so may cause the back door to operate unintentionally if the power back door switch is accidentally touched, resulting in hands and fingers being caught and injured.

Installing the spare tire

1. Remove any dirt or foreign matter from the wheel contact surface.

If foreign matter is on the wheel contact surface, the wheel nuts may loosen while the vehicle is in motion, causing the tire to come off.

2. Install the spare tire and loosely tighten each wheel nut by hand by approximately the same amount.

Tighten the wheel nuts until the tapered portion A comes into loose contact with the disc wheel seat B.

3. Install the wheel nut wrench in jack handle.

4. Lower the vehicle.

5. Firmly tighten each wheel nut two or three times in the order shown in the illustration.

Tightening torque: 76 ft*lbf (103 N*m, 10.5 kgf*m)

6. Stow the flat tire, tire jack and all tools.

■The compact spare tire
