Maintenance and care
■Situations in which the tire pressure warning system may not oper-
ate properly
●In the following cases, the tire pressure warning system may no t 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 replac ed with a tire that is not of the specif ied size.
• Tire chains, etc., are equipped.
• An auxiliary-supported ru n-flat tire is equipped.
• If a window tint that affects the radio wave signals is instal led.
• 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 sp ecified
level.
• If wheel without the tire pressure warning valve and tranmitter is used.
• If the ID code on the tire pressure warning valves and transm itter 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 stat ion, large
display, airport or other facilit y that generates strong radio waves or
electrical noise
• When carrying a portable radio, cellular phone, cordless phone or
other wireless communication device
If tire position information is not correctly displayed due to the radio
wave conditions, the display may be corrected by driving and ch anging
the radio wave conditions.
●When the vehicle is parked, the time taken for the warning to s tart 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 initialization 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 has been turned to the
“ON” position 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.
●While the position of each tire is being determined and the inf lation pres-
sures are not being displayed on the multi-information display, if the
inflation pressure of a tire drops, the tire pressure warning l ight will come
on.
■Warning performance of the tire pressure warning system
The warning of the tire pressu re warning system will change in accor-
dance with the conditions under which it was initialized. For t his reason,
the system may give a warning even if the tire pressure does no t reach a
low enough level, or if the pressure is higher than the pressur e that was
adjusted to when the sys tem was initialized.

Maintenance and care
■When initialization of the tire pressure warning system has fai led
Initialization may take longer to complete if the vehicle is driven on an
unpaved road. When performing ini tialization, drive on a paved road if
possible. Depending on the driving environment and condition of the tires,
initialization will be completed i n approximately 10 to 30 minutes. If initial-
ization is not complete after dr iving approximately 10 to 30 mi nutes, con-
tinue driving for a while.
If the inflation pressure of each tire is not displayed after d riving for
approximately 1 hour, perf orm the following procedure.
●Park the vehicle in a safe place for approximately 20 minutes. Then
drive straight (with occasional left and right turns) at approx imately
25 mph (40 km/h) or more for approximately 10 to 30 minutes.
However, in the following situatio ns, the tire inflation pressure will not be
recorded and the system will not operate properly. Perform initialization
again.
●When operating the tire pressure warning reset switch, the tire pressure
warning light does not blink 3 times.
●After performing initi alization, the tire pressure warning ligh t blinks for 1
minute then stays on while d riving about 20 minutes.
If the inflation pressure of eac h tire is still not displayed, have the vehicle
inspected by you r Toyota dealer.
