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.

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 com-
pared 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)

form 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.

The sealant has a limited lifespan. The expiry date is marked on the bottle.
The sealant should be replaced before the expiry date. Contact any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional 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 sealant in the bottle and other
parts of the kit have been used and need to be purchased, contact any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
The sealant can be used when the outside temperature is from -30 C (-22
F) to 60 C (140 F).
The kit is exclusively designed for size and type of tires originally installed
on your vehicle. 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 operation noise is produced. This does
not indicate a malfunction.
