Improper use of the tire jack may cause the vehicle to suddenly fall off
the jack, leading to death or serious injury.
●Do not use the tire jack for any purpose other than replacing t ires or
installing and removing tire chains.
●Only use the tire jack that comes with this vehicle for replacing a flat

4RUNNER (U)
Repeat step any time the tire is lowered or disturbed.
Stow the tools and jack securely.
■After completing the tire change
The tire pressure warni ng system must be reset. ( P. 430)
■When using the spare tire (veh icles without P245/60R20 tires)
As the 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 spar e tire after
the tire pressure wa rning light comes on, the light remains on.
NOTICE
■Do not drive the vehicle with a flat tire
Do not continue driving with a flat tire.
Driving even a short distance wit h a flat tire can damage the tire and the
wheel beyond repair.
■When stowing the flat tire
Ensure that there is no object c aught between the tire and the vehicle
underbody.
■When replacing the tires
●When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitter, contact your Toyota dealer as the tire p ressure
warning valve and transmitter may be damaged if not handled cor -
rectly.
●Replace the grommets for the tire pressure warning valves and trans-
mitters as well.
■To avoid damage to the tire pressure warning valves and transmi t-
ters
When a tire is repaired with liquid sealants, the tire pressure warning valve and transmitter may not operate properly. If a liquid sea lant is
used, contact your Toyota dealer or other qualified service shop as soon
as possible. Make sure to replace the tire pressure warning valve and
transmitter when replacing the tire. ( P. 430)
