Front | Left-hand side | Behind the rear right-hand side tire |
Right-hand side | Behind the rear left-hand side tire | |
Rear | Left-hand side | In front of the front right-hand side tire |
Right-hand side | In front of the front left-hand side tire |
2. Slightly loosen the wheel nuts (one turn).
For vehicles with wheel lock nuts, loosen the wheel lock nut first.
3. Turn the tire jack portion A by hand until the notch of the jack is in contact with the jack point.
The jack point guides are located under the rocker panel. They indicate the jack point positions.
4. Raise the vehicle until the tire is slightly raised off the ground.
5. Remove all the wheel nuts and the tire.
When resting the tire on the ground, place the tire so that the wheel design faces up to avoid scratching the wheel surface.
■ If the spare tire cannot be lowered (RX450hL) If the spare tire cannot be lowered, it may not have been stowed properly. Perform the following procedure:
1. Fully tighten the spare tire clamp bolt by turning the jack handle clockwise until two clicks are heard and the jack handle skips.
2. Turn the jack handle counterclockwise to lower the spare tire.
If the spare tire still cannot be lowered, attempt to fully tighten the spare tire clamp bolt again by turning the jack handle clockwise.
Then turn it counterclockwise at least 2 turns to lower the spare tire.

WARNING
■When holding a tire with Selectable Color Trim (if equipped)
Do not hold the tire by the Selectable Color Trim. Otherwise, the Selectable Color Trim may be damaged or may fall off causing the tire to drop, possibly causing injury.
■ Replacing a flat tire
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.
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.
■ 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 comes into loose contact with the disc wheel seat.
3. Lower the vehicle.
4. Firmly tighten each wheel nut two or three times in the order shown in the illustration.
For vehicles with wheel lock nuts, tighten the wheel lock nut last Tightening torque: 76 ft*lbf (103 N*m, 10.5 kgf*m)
5. RX450h: Stow the flat tire, tire jack and all tools.
WARNING
■ Stowing the flat tire Failure to follow steps listed under stowing the tire may result in damage to the spare tire carrier and loss of the tire, which could result in serious injury or death.
Stowing the flat tire, jack and all tools (RX450hL)
1. Remove the center wheel ornament by pushing from the reverse side.
Be careful not to lose the wheel ornament.
2. Stand the tire against the bumper with the inner surface facing toward you. Pass the hoist assembly C and holding bracket B through the wheel opening.
3. Fully depress the secondary latch A and install the bracket B to the hoist assembly C.
4. Lay the tire on the ground with the outer surface (valve stem) facing up.
5. Before raising the tire, make sure that the hoist assembly is perpendicular to the wheel opening. (Try to place the tire directly beneath the vehicle, near where the wire cable is hanging from.)
6. Using the jack handle and adapter socket, tighten the tire clamp bolt by turning it clockwise until the tire is in the correct position and two clicks are heard as the jack handle skips.
7. Confirm it is not loose after tightening:
Visually check to ensure tire is not hung on surrounding parts.
If looseness or misassembly exists, repeat steps 2 to 7.
8. Repeat step 7, any time the tire is lowered or disturbed.
9. Stow the jack and all tools.
