To equalize tire wear and extend
tire life, Toyota recommends that
tire rotation is c arried out at the
same interval as tire inspection. Do not fail to initialize the tire pres-
sure warning system after tire rota-
tion.
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.

The tire pressure detected by
the tire pressure warning sys-
tem can be displayed on the
multi-information display.
( P.87, 96)
NOTICE
■If tire inflation pressure of
each tire becomes low while
driving
Do not continue driving, or your
tires and/or wheels may be
ruined.

■Routine tire inflation pressure
checks
The tire pressure warning system
does not replace routine tire inflation
pressure checks . Make sure to
check tire inflation pressure as part
of your routine o f daily vehicle
checks.
■Situations in which the tire
pressure warning system may
not operate properly
●In the following cases, the tire
pressure 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
Equipment) tire.
• A tire has been replaced with a
tire that is not of the specified size.
• Tire chains, etc. are equipped.
• An auxiliary-support ed run-flat tire
is equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on

3986-3. Do-it-yourself maintenance
the vehicle, particularly around the
wheels or wheel housings.
• If the tire inflation pressure is
extremely higher than the speci-
fied level.
• If the spare tire is in a location
subject to poor radio wave signal
reception.
*
• If wheel without the tire pressure warning valve and transmitter is
used.
• If the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure
warning computer.
*: Vehicles with full-size spare tire
only
●Performance may be affected in
the following situations.
• Near a TV tower, electric power plant, gas station, radio station,
large display, airpo rt or other facil-
ity 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
changing the radio wave condi-
tions.
●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
The warning of the tire pressure
warning system will change in
accordance with th e 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 replacing tires or wheels,
tire pressure warning valves and
transmitters must also be
installed.
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure
warning computer and the tire
pressure warning system must
be initialized. Have tire pressure
warning valves and transmitter
ID codes registered by your Toy-
ota dealer. ( P.401)
■Replacing tires and wheels
If the ID code of the tire pressure
warning valve and tr ansmitter is not
registered, the tire pressure warning
system will not work properly. After
driving for about 20 minutes, the tire
pressure warning light blinks for 1
minute and stays on to indicate a
system malfunction.

Maintenance and care
■Initializing the tire pressure
warning system
Initialize the syst em with the tire
inflation pressure adjusted to the
specified level.
■Initialization procedure
●Make sure to carry out initializa-
tion after adjusting the tire inflation
pressure.
Also, make sure the tires are cold
before carrying out initialization or
tire inflation pressure adjustment.
●If you have accidentally turned the
engine switch off during initializa-
tion, it is not necessary to restart
the initialization ag ain as initializa-
tion will restart aut omatically when
the engine switch has been turned
to ON for the next time.
●If you accidentally restart the ini-
tialization when ini tialization is not
necessary, adjust the tire inflation
pressure to the specified level
when the tires are cold, and con-
duct initialization again.
●While the position of each tire is
being determined and the inflation
pressures are not being displayed
on the multi-information display, if
the inflation pres sure of a tire
drops, the tire pressure warning
light will come on.
■When initialization of the tire
pressure warning system has
failed
Initialization may take longer to
complete if the vehicle is driven on
an unpaved road. When performing
initialization, drive on a paved road if
possible. Depending on the driving
environment and condition of the
tires, initialization will be completed
in approximately 10 to 30 minutes. If
initialization is n ot complete after
driving approximately 10 to 30 min-
utes, 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 30 minutes.
However, in the following situations,
the tire inflation pr essure will not be
recorded and the system will not
operate properly. Perform initializa-
tion again.
●If the vehicle is reversed during
initialization, the data up to that
point is reset, so perform the ini-
tialization procedure again from
the beginning.
●When operating the tire pressure
warning reset switch, the tire pres-
sure warning light does not blink 3
times.
●After performing initialization, the
tire pressure warn ing light blinks
for 1 minute then stays on while
driving.
If the inflation pressure of each tire
is still not displayed, have the vehi-
cle inspected by your Toyota dealer.
Every tire pressure warning
valve and transmitter has a
unique ID code. When replacing

WARNING
■When initializing the tire pres-
sure warning system
Do not initializing tire inflation
pressure without f irst adjusting
the tire inflation pressure to the
specified level. Otherwise, the tire
pressure warning light may not
come on even if the tire inflation
pressure is low, or it may come on
when the tire inflation pressure is
actually normal.

■When registering ID codes
●ID code registrati on is performed
while driving at a vehicle speed of
approximately 25 mph (40 km/h)
or more.
●Before performing ID code regis-
tration, make sure that no wheels
with tire pressure warning valve
and transmitters installed are near
the vehicle.
●Make sure to initi alize the tire
pressure warning system after
registering the ID codes. If the
system is initialized 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.
■Canceling ID code registration
●To cancel ID code registration
after it has been started, turn the
engine switch off before driving
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 off before driving.
●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-

1 Remove the tire valve cap. 2
Press the tip of the tire pres-
sure gauge onto the tire
valve.
3 Read the pressure using the
gauge gradations.
4 If the tire inflation pressure is
not at the recommended
level, adjust the pressure.
If you add too much air, press
the center of the valve to
deflate.
5 After completing the tire infla-
tion pressure measurement
and adjustment, apply soapy
water to the valve and check
for leakage.
6 Put the tire valve cap back
on.
■Tire inflation pressure check
interval
You should check ti re inflation pres-
sure every two week s, or at least
once a month. Do not forget to
check the spare.
■Effects of incorrect tire inflation
pressure
Driving with incorrec t tire inflation
pressure may resul t in the following:
●Reduced fuel economy
●Reduced driving comfort and poor
handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating,
have it checked by your Toyota
dealer.

sure, observe the following:
●Check only when the tires are
cold.
If your vehicle has been parked for
at least 3 hours or has not been
driven for more tha n 1 mile or 1.5
km, you will get an accurate cold
tire inflation pressure reading.
●Always use a tire pressure gauge.
It is difficult to judge if a tire is
properly inflated based only on its
appearance.
●It is normal for the tire inflation
pressure to be higher after driving
as heat is generated in the tire. Do
not reduce tire inflation pressure
after driving.
●Never exceed the vehicle capacity
weight.
Passengers and luggage weight
should be placed so that the vehi-
cle is balanced.
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 possibility 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 no t installed, dirt
or moisture may get into the valve
and cause an air leak, resulting in
decreased tire inflation pressure.
