■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.

■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.

■Emergency tire puncture repair kit
●The sealant has a limited life span. The expiry date is marked on the bottle. The sealant should be replaced before the expiry da te. Contact any authorized Lexus dealer or repairer, or another duly qualified an d equipped professional for replacement.
●The sealant stored in the emergency tire puncture repair kit can be used only once to temporarily repair a single tire. If the seal ant has been used and needs to be purchased, contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional. The compressor is reusable.
●The compressor can be used repeatedly.
●The sealant can be used when the outside temperature is from -40 C (-40F) to 60C
(140 F).
●The kit is exclusively designed for size and type of tires originally installed on your vehi- cle. Do not use it for tires that a different size than the original ones, or for any other
purposes.
●If the sealant gets on your clothes, it may stain.
●If the sealant adheres to a wheel or the surface of the vehicle body, the stain may not be
removable if it is not cleaned at once. Immediately wipe away the sealant with a wet cloth.
●During operation of the kit, a loud operatio n noise is produced. This does not indicate a
malfunction.
●Do not use to check or to adjust the tire pressure.
■If the tire is inflated to mo re than the recommended level
Disconnect the hose from the valve.
Disconnect the hose from the valve, remove the air release cap from the hose and then reconnect the hose.
Turn the compressor switch on and wait for several seconds, then turn it off. Check that
the air pressure indicator sh ows the recommended level. (P. 737) If the air pressure is lower than the reco mmended level, turn the compressor switch on again and repeat the inflation procedure un til the recommended pressure is reached.
■After a tire repaired with the emergency tire puncture repair kit
●The tire pressure warning valve and transmitter should be replaced.
●Even if the tire inflation pressure is at the recommended level, the tire pressure warning
light may come on/flash.
Install the air release cap to the end of the
hose and push the protrusion on the air release cap into the valve to let some air out.
