■When a tire is replaced with a spare tire
Vehicles with a compact spare tire: The compact spare tire is not equipped with a tire
pressure warning valve and transmitter. If a tire goes flat, the tire pressure warning
light will not turn off even though the flat tire has been replaced with the spare tire.
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
inflation pressure of the spare tire is low. If a tire goes flat, the tire pressure warning
light will not turn off even though the flat tire has been replaced with the spare tire.
■Conditions that the tire pressure warning system may not function properly

CAUTION
■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 could cause an accident resulting in death or serious injury.
■When the electric power steering system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold firmly and
operate using more force than usual.
■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 pres-
sure immediately.
●If the tire pressure warning light comes on even after tire inflation pressure adjust-
ment, 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 professional.
●Avoid abrupt maneuvering and braking. If the 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 warn-
ing system may not operate properly.

■The 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. 6 4 5 )
■When using the compact spare tire (vehicles with the tire pressure warning sys-
tem)
As the compact spare tire is not equipped with a tire pressure warning valve and
transmitter, 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 warning light comes on, the light remains on.
■When the compact spare tire is equipped
The vehicle becomes lower when driving with the compact spare tire compared to
when driving with standard tires.
■If you have a flat rear tire on a road covered with snow or ice (vehicles with front
and rear tires of the same size and compact spare tire only)
Install the compact spare tire on one of the front wheels of the vehicle. Perform the
following steps and fit tire chains to the rear tires:
Replace a front tire with the compact spare tire.
Replace the flat rear tire with the tire removed from the front of the vehicle.
Fit tire chains to the rear tires.

■If the tire is inflated to more than the recommended levelDisconnect 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, and then turn it off.
Check that the air pressure indicator shows the recommended level. ( →P. 6 4 5 )
If the air pressure is lower than the recommended level, turn the compressor
switch on again and repeat the inflation procedure until the recommended pres-
sure is reached.
■The valve of a tire that has been repaired
●After a tire is repaired with the emergency tire puncture repair kit, the valve should
be replaced.
●Vehicles with the tire pressure warning system: After a tire is repaired with the
emergency tire puncture repair kit, even if the tire inflation pressure is at the recom-
mended level, the tire pressure warning light may come on/flash.
■Note for checking the emergency tire puncture repair kit
Check the sealant expiry date occasionally.
The expiry date is shown on the bottle.
Do not use sealant whose expiry date has already passed. Otherwise, repairs con-
ducted using the emergency tire puncture repair kit may not be performed properly. Install the air release cap to the end of the
hose and push the protrusion on the air
release cap into the tire valve to let some air
out.
CAUTION
■Caution while driving
Observe the following precautions.
Failure to do so may cause an accident.
●The emergency tire puncture repair kit is made exclusively for your vehicle. Do
not use it on other vehicles.
●Do not use the emergency tire puncture repair kit for tires that are a different size
than the specified ones or for any other purpose. Doing so may cause the tires to
not be repaired properly.
