■When a tire is replaced with a spare tire
Vehicles with a compact spare tire: The comp act spare tire is not equipped with a tire pressure warning valve and transmitter. If a ti re goes flat, the tire pressure warning light
will not turn off even though th e flat tire has been replaced with the spare tire. Replace the spare tire with the repaired tire and adjust the tire inflation pressure. The tire pressurewarning light will go off after a few minutes.
Vehicles with a full-size spare tire: The spare tire is also equipped with a tire pressure warning valve and transmitter. The tire pressure warning light will turn on if the tire infla- tion pressure of the spare tire is low. If a ti re goes flat, the tire pressure warning light will
not turn off even though the flat tire has been replaced with the spare tire. Replace the spare tire with the repaired tire and adjust the tire inflation pressure. The tire pressure warning light will go off after a few minutes.
■Conditions that the tire pressure warning system may not function properly
P. 618
■Warning buzzer
In some cases, the buzzer may not be heard due to being in a noisy location or audio sound.
WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional. The vehicle will become extremely unstable during braking, and the ABS system may fail, which couldcause an accident resulting in death or serious injury.
■When the electric power steering system warning light comes on
When the light comes on yellow, the assist to the power steering is restricted. When the light comes on red, the assist to the power steering is lost and handling operations of
the steering wheel become extremely heavy. When steering wheel operations are heavier than usual, grip the steering wheel firmly and operate it using more force than usual.

WARNING
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause a loss of vehicle control and result in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pressureimmediately.
●Vehicles with a spare tire: If the tire pressure warning light comes on even after tire
inflation pressure adjustment, it is probable that you have a flat tire. Check the tires. If a tire is flat, change it with the spare tire and have the flat tire repaired by the nearest any authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
●Vehicles with an emergency tire puncture repair kit: If the tire pressure warning light comes on even after tire inflation pressure adjustment, it is probable that you have a
flat tire. Check the tires. If a tire is flat, re pair the flat tire by using emergency tire punc- ture repair kit.
●Avoid abrupt maneuvering and braking. If th e vehicle tires deteriorate, you could lose
control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.
NOTICE
■To ensure the tire pressure warning system operates properly
Do not install tires with different specifications or makers, as the tire pressure warning system may not operate properly.

WARNING
■When holding a tire with Selectable Color Trim (if equipped)
■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 area s 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 tireto 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 103 N·m (10.5 kgf·m,
76 ft·lbf) 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 any authorized Lexus dealer orrepairer, or another duly qualif ied and equipped professional.
• Do not attach a heavily damaged wheel or nament, 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 canceling the power back door sys- tem ( P. 115). 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.
Do not hold the tire by the Selectable Color
Trim. Otherwise, the Selectable Color Trim may be damaged or may fall off causing the tireto drop, possibly causing injury.

Firmly tighten each wheel nut two or
three times in the order shown in the
illustration.
Tightening torque:
103 N·m (10.5 kgf·m, 76 ft·lbf)
Vehicles with a full-size spare tire:
Reinstall the wheel ornament.
Stow the flat tire, tire jack and all tools.
■The compact spare tire (vehicles with a compact spare tire)
●The compact spare tire is identified by the label “TEMPORARY USE ONLY” on the
tire sidewall. Use the compact spare tire temporarily, and only in an emergency.
●Make sure to check the tire inflation pressure of the compact spare tire. (P. 737)
■When using the compact spare tire (vehicles with a compact spare tire)
As the compact spare tire is not equipped with a tire pressure warning valve and trans- mitter, low inflation pressure of the spare tire will not be indicated by the tire pressure
warning system. Also, if you replace the compact spare tire after the tire pressure warn- ing light comes on, th e light remains on.
■When the compact spare tire is equipped (vehicles with a compact spare tire)
When driving with the compact spare tire installed, the vehicle height will be different than when driving with standard tires.
■If you have a flat front tire on a road covered with snow or ice (vehicles with a compact
spare tire)
Install the compact spare tire on one of the rear wheels of the vehicle. Perform the follow- ing steps and fit tire chains to the front tires:
Replace a rear tire with the compact spare tire.
Replace the flat front tire with the tire removed from the rear of the vehicle.
Fit tire chains to the front tires.
