every 5000 km (3000 miles).
Do not fail to initial ize the tire pressure
warning system after tire rotation.
Front
■When rotating the tires
Make sure that the power switch is OFF. If the tires are rotated while the power
switch is in ON, the tire position informa -
tion will not be updated.
If this accidentally occurs, either turn the
power switch to OFF and then to ON, or
initialize the system after checking that
the tire pressure is properly adjusted.
Your vehicle is equi pped with a tire
pressure warning system that uses
tire pressure warning valves and
transmitters to detect low tire infla -
tion pressure before serious prob -
lems arise.
The tire pressure warning system
of this vehicle adopts a 2-type
warning system
When “Adjust Pressure” is dis-
played (Normal Warning)
The tire pressure warning light comes
on and a buzzer sounds when the tire
inflation pressure becomes low due to
natural air leakage or outside tempera-
ture. (Ways of coping: →P.575, 624)
When “Immediately Check tire
when Safe” is displayed (Emer -
gency Warning)
The tire pressure warning light comes
on and a buzzer sounds when the tire
inflation pressure becomes low sud -
denly due to a blowout. (Ways of cop -
ing: →P.575, 582, 593)
However, the system may not be able
to detect sudden tire ruptures (bursting,
etc.).
The tire pressure detected by the
tire pressure warning system can
be displayed on the multi-informa -
tion display.
The unit can be changed.
■How to change the unit
1 Park the vehicle in a safe place
and turn the power switch off.
Changing the unit cannot be performed while the vehicle is moving.
2 Turn the power switch to ON.

■Routine tire inflation pressure checks
The tire pressure w arning system does
not replace routine tire inflation pressure checks. Make sure to check tire inflation
pressure as part of your routine of daily
vehicle checks.
■Tire inflation pressure
●It may take a few minutes to display
the tire inflation pressure after the
power switch is turned to ON. It may also take a few minutes to display the
tire inflation pressu re after inflation
pressure has been adjusted.
●Tire inflation pre ssure changes with
temperature. The displayed values may also be different from the values
measured using a tire pressure
gauge.
■Situations in which the tire pres - sure warning system may not oper -
ate properly
●In the following cases, the tire pres -
sure warning system may not operate
properly. • If non-genuine Toyota wheels are
used.
• A tire has been r eplaced with a tire that is not an OE (Original Equipment)
tire.
• A tire has been r eplaced with a tire that is not of the specified size.
• Tire chains, etc. are equipped.
• An auxiliary-supporte d run-flat tire is equipped.
• If a window tint tha t 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 t han the specified
level. • If wheels without tire pressure warning
valves and transmitters 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 dis -
play, airport or ot her facility that gen- erates strong radio waves or electrical
noise
• When carrying a port able radio, cellu-
lar phone, cordless phone or other wireless communication device
If tire position information is not cor -
rectly displayed due to the radio wave conditions, the display may be cor -
rected by driving and changing the
radio wave conditions.
●When the vehicle is parked, the time

Maintenance and care
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.
■Warning performance of the tire
pressure warning system
The warning of the tire pressure warning
system will change i n accordance with
the conditions under which it was initial - ized. For this reaso n, 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.
