■When rotating the tires (vehi-
cles with tire pressure warning
system)
Make sure that the engine switch is
OFF. If the tires are rotated while
the engine switch i s in ON, the tire
position informa tion will not be
updated. If this accidentally occurs,
either turn the engine switch to OFF
and then to ON, or initialize the sys-
tem after checking that the tire pres-
sure is properly adjusted.
Your vehicle is equipped with a
tire pressure warning system
that uses tire pressure warning
valves and transmitters to detect
low tire inflation pressure before
serious problems arise.
If the tire pressure drops
below a predetermined level,
the driver is warned a screen

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.
■Warning performance of the tire
pressure warning system (if
equipped)
The warning of the tire pressure
warning system w ill change in
accordance with the conditions
under which it was initialized. For
this reason, the system may give a
warning even if th e 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.

Maintenance and care
Even if the vehicle is not driven at
approximately 25 mph (40 km/h) or
more, registration can be com-
pleted by driving for a long time.
However, if registration does not
complete after driving for 1 hour or
more, perform the procedure again
from the beginning.
7Initialize the tire pressure
warning system. ( P.598)
■When registering ID codes
●ID code registration is performed
while driving at a vehicle speed of
approximately 25 mph (40 km/h)
or more.
●Before performin g ID code regis-
tration, make sure that no wheels
with tire pressur e warning valve
and transmitters installed are near
the vehicle.
●Make sure to initialize the tire
pressure warning system after
registering the ID codes. If the
system is initializ ed before regis-
tering the ID codes, the initialized
values will be invalid.
●ID codes can be registered by
yourself, but depending on the
driving conditions and driving
environment, registration may
take some time to complete.
●As the tires will be warm when
registration is completed, make
sure to allow the tires to cool
before performing initialization.
■Canceling ID code registration
●To cancel ID code registration
after it has been started, turn the
engine switch to OFF before driv-
ing the vehicle. If the vehicle is
driven after ID code registration is
started, to cancel registration, per-
form the ID code registration start
procedure again and turn the
engine switch to OFF before driv-
ing.
●If ID code registration has been
canceled, the tire pressure warn- ing light will blin
k for approxi-
mately 1 minute when the engine
switch is turned to ON and then
illuminate. The tire pressure warn-
ing system will be operational
when the tire pressure warning
light turns off.
●If the warning lig ht does not turn
off even after several minutes
have elapsed, ID code registration
may not have been canceled cor-
rectly. To cancel registration, per-
form the ID code registration start
procedure again and then turn the
engine switch to OFF before driv-
ing.
■If ID codes are not registered
properly
In the following situations, ID code
registration may take longer than
usual to be completed or may not be
possible. Norma lly, registration
completes within approximately 30
minutes.
If ID code registration is not com-
plete after driving for approximately
30 minutes, continue driving for a
while.
• Vehicle is not pa rked for approxi-
mately 20 minutes or more before
driving
• Vehicle is not driven at approxi- mately 25 mph (40 km/h) or more
• Vehicle is driven on unpaved roads
• Vehicle is driven near other vehi- cles and system cannot recog-
nize tire pressure warning valve
and transmitters o f your vehicle
over those of other vehicles
• Wheel with tire p ressure warning
valve and transmitter installed is
inside or near the vehicle
If registration does not complete
after driving for 1 hour or more, per-
form the ID code registration proce-
dure again from the beginning.
●If the vehicle is reversed during
registration, the data up to that
point is reset, so p erform the reg-
6067-3. Do-it-yourself maintenance
When replacing wheels, care
should be taken to ensure that
they are equivalent to those
removed in load capacity, diam-
eter, rim width and inset
*.
Replacement wheels are avail-
able at your Toyota dealer.
*: Conventionally referred to as off- set.
Toyota does not recommend
using the following:
Wheels of different sizes or
types
Used wheels
Bent wheels that have been
straightened
■When replacing wheels (vehi-
cles with tire p ressure warning
system)
The wheels of your vehicle are
equipped with tire pressure warning
valves and transmitters that allow
the tire pressure warning system to
provide advance warning in the
event of a loss in tire inflation pres-
sure. Whenever wheels are
replaced, tire pressure warning
valves and transmitters must be
installed. ( P.592, 607)
WARNING
■Proper inflation is critical to
save tire performance
Keep your tires properly inflated.
If the tires are not properly
inflated, the following conditions
may occur which could lead to an
accident resulting in death or seri-
ous injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting
from overheated tires
●Air leaking from between tire
and wheel
●Wheel deformation and/or tire
damage
●Greater possibilit y of tire dam-
age while driving (due to road
hazards, expansion joints,
sharp edges in the road, etc.)
NOTICE
■When inspecting and adjust-
ing tire inflation pressure
Be sure to put the tire valve caps
back on.
If a valve cap is not installed, dirt
or moisture may get into the valve
and cause an air leak, resulting in
decreased tire inflation pressure.
Wheels
If a wheel is bent, cracked or
heavily corroded, it should
be replaced. Otherwise, the
tire may separate from the
wheel or cause a loss of
handling control.
