5-2. Steps to take in an emergency
CAUTION
TPMS (tire pressure warning system) malfunctions may occur for a vari-
ety of reasons, including the installati
on of replacement or alternate tires
or wheels on the vehicle that prevent the TPMS (tire pressure warning
system) from functioning properly. Always check the TPMS (tire pres-
sure warning system) malfunction te lltale after replacing one or more
tires or wheels on your vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS (tire pressure warning system) to
continue to function properly.
nIf the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could
cause loss of vehicle control and result in death or serious injury.
lStop your vehicle in a safe place as soon as possible. Adjust the tire
inflation pressure immediately.
lIf the tire pressure warning light comes on even after tire inflation pres-
sure adjustment, it is pr obable that you have a flat tire. Check the tires.
If the tire is flat, change to the spare tire and have the flat tire repaired
by the nearest Toyota dealer.
lAvoid abrupt maneuvering and braking. If the vehicle tires deteriorate,
you could lose control of the steering wheel or the brakes.
nIf a blowout or sudden air leakage should occur
The tire pressure warning syste m may not activate immediately.
NOTICE
nPrecaution when installing a different tire
When a tire of a different specification or maker is installed, the tire pres-
sure warning system may not operate properly.

nCompact spare tire
The compact spare tire saves space in your luggage compartment,
and its lighter weight helps to enhance fuel economy and permits
easier installation in case of a flat tire.
The compact spare tire is
designed for temporary emer-
gency use only.
The compact spare tire is identi-
fied by the distinctive wording
“TEMPORARY USE ONLY”
molded into the sidewall of the
tire.
nWhen using the compact spare tire
As the compact spare tire is not equipped with the tire pressure warning
valve and transmitter, low inflation pr essure of the compact spare tire will
not be warned. Also, if you replace the compact spare tire after the tire
pressure warning light comes on, the light remains on.
nCheck the tire inflation pressure of the compact spare tire. ( →P.
