The initialization operation
●Make sure to carry out initializ
ation after adjusting the tire inflation pres-
sure.
Also, make sure the tires are co ld before carrying out initialization or tire
inflation pressure adjustment.
●If you have accidentally turned the engine switch off during in itialization,
it is not necessary to press the reset swit ch again as initialization will
restart automatically when the en gine switch to the “ON” position (vehi-
cles without a smart key system) or IGNITION ON mode (vehicles with a
smart key system) for the next time.
●If you accidentally press the reset switch when initialization is not neces-
sary, adjust the tire inflation pressure to the specified level when the
tires are cold, and cond uct initialization again.
■Warning performance of the tire pressure warning system
The warning of the tire pressu re warning system will change in accor-
dance with driving conditions. F or this reason, the system may give a
warning even if the tire pressure does not reach a low enough l evel, or if
the pressure is higher than the pressure that was adjusted to w hen the
system was initialized.
■When initialization of the tire pressure warning system has fai led
Initialization can be completed i n a few minutes. However, in the following
cases, the settings have not been record ed and the system will not oper-
ate properly. If repeated attempts to record tire inflation pre ssure settings
are unsuccessful, have the vehicl e inspected by your Toyota dealer.
●When operating the initialization of the system, the tire pressure warning
light does not blink 3 times and the setting message does not a ppear on
the multi-information display.
●After driving for a certain period of time since the initializa tion has been
completed, the warning light comes on after blinking for 1 minute.

Tightening torque:
76 ft
·lbf (103 N·m, 10.5 kgf·m)
Stow the flat tire, tire jack and all tools.
■The compact spare tire
●The compact spare tire is identified by the label “TEMPORARY US E
ONLY” on the tire sidewall.
Use the compact spar e tire temporarily, and only in an emergenc y.
●Make sure to check the tire inflation pressure of the compact spare tire.
( P. 4 8 2 )
■After completing the tire change
The tire pressure warni ng system must be reset. ( P. 378)
■When using 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 rep lace the
compact spare tire after the tire pressure warning light comes on, the light
remains on.
■When the compact spa re tire is equipped
The vehicle becomes lower when driving with the compact spare t ire
compared to when driving with standard tires.
■If you have a flat front tire on a road covered with snow or ic e
Install the compact spare tire on one of the rear wheels of the vehicle.
Perform the following steps and f it 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 vehi-
cle.
Fit tire chains to the front tires.
