Initializing the tire pressure warning system
Initialize the system with the tire infl
ation pressure adjusted to the speci-
fied level.
■If the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of the tire s as snow tires is lost.
■If you press the tire pressure warning reset switch accidentally
If initialization is performed, adjust the tire inflation pressure to the speci-
fied level and initialize the tire pressure warning system again.
■Situations in which the tire pressure warning system may not oper-
ate properly
●In the following cases, the tire pr essure warning system may not operate
properly.
• If non-genuine Toyota wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equip- ment) tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains etc. are equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the
wheels or wheel housings.
• If the tire inflation pressure is extremely higher than the specified
level.
• If tires not equipped with tire pressure warning valves and transmit- ters are used.
• If the ID code on the tire pressure warning valves and transmitters is not registered in the tire pressure warning computer.
●Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large
display, airport or other facility that generates strong radio waves or
electrical noise
• When carrying a portable radio, cellular phone, cordless phone or
other wireless communication device
Vehicles with a tire inflation pressure display function: If tire position
information is not correctly displayed due to the radio wave conditions,
the display may be corrected by driving and changing the radio wave
conditions.
●When the vehicle is parked, the time taken for the warning to start or go
off could be extended.
●When tire inflation pressure declines rapidly for example when a tire has
burst, the warning may not function.

The initialization operation
●Make sure to carry out in
itialization after adjusting the tire inflation pres-
sure.
Also, make sure the tires are cold be fore carrying out initialization or tire
inflation pressure adjustment.
●If you have accidentally turned the engine switch to off during initializa-
tion, it is not necessary to press th e reset switch again as initialization
will restart automatically when the engine switch has been turned to
IGNITION ON mode for the next time.
●If you accidentally press the reset s witch when initialization is not neces-
sary, adjust the tire inflation pressu re to the specified level when the
tires are cold, and conduct initialization again.
●While the position of each tire is being determined and the inflation pres-
sures are not being displayed on the multi-information display, if the
inflation pressure of a tire drops, the tire pressure warning light will come
on.
■Warning performance of the ti re pressure warning system
The warning of the tire pressure warning system will change in accor-
dance with the conditions under which it was initialized. For this reason,
the system may give a warning even if the tire pressure does not reach a
low enough level, or if the pressure is higher than the pressure that was
adjusted to when the system was initialized.
■When initialization of the tire pr essure warning system has failed
Initialization may take longer to comp lete if the vehicle is driven on an
unpaved road. When performing initia lization, drive on a paved road if
possible. Depending on the driving environment and condition of the tires,
initialization will be completed in approx imately 10 minutes. If initialization
is not complete after driving approxima tely 10 minutes, continue driving
for a while.
If the inflation pressure of each tire is not displayed after driving for
approximately 1 hour, perform the following procedure.
●Park the vehicle in a safe place for approximately 20 minutes. Then
drive straight (with occasional left and right turns) at approximately 25
mph (40 km/h) or more for approximately 10 to 20 minutes.

However, in the following situations, the tire inflation pressure will not be
recorded and the system will not operate properly. Perform initialization
again.
●When operating the tire pressure wa rning reset switch, the tire pressure
warning light does not blink 3 times.
●After performing initialization, the ti re pressure warning light blinks for 1
minute then stays on while driving.
If the inflation pressure of each tire is still not displayed, have the vehicle
inspected by your Toyota dealer.

● “Engine Coolant Temp is High” is shown on the multi-information
display.
● Steam comes out from under the hood.
Stop the vehicle in a safe place and turn off the air conditioning sys-
tem, and then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the engine has cooled
down sufficient ly, inspect the
