How to register the ID codes
Select on the multi-information display using the meter con-
trol switches on the steering wheel. ( P. 9 6 )
Select “Vehicle Settings” and then press and hold .
Select “TPWS” and then press .
Select “Change Wheel Set”
then press and hold until
the tire pressure warning
light blinks slowly 3 times.
Then a message will be dis-
played on the multi-information
display.
When registration is being per-
formed, the tire pressure warn-
ing light will blink for
approximately 1 minute then
illuminate and “---” will be dis-
played for the inflation pres-
sure of each tire on the multi-
information display.
Drive straight (with occasional left and right turns) at approxi-
mately 25 mph (40 km/h) or more for approximately 10 to 30 min-
utes.
Registration is complete when the tire pressure warning light t urns
off and the inflation pressure of each tire is displayed on the multi-
information display.
Registration may take longer than approximately 1 hour in certain
situations, such as when the veh icle is stopped for a long time at
traffic lights, etc. ( P. 432)
After registering the ID codes, make sure to initialize the tir e pres-
sure warning system. ( P. 425)

■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cracks deep enough t o
expose the fabric, and bulges indicating internal damage
●A tire goes flat repeatedly or c annot be properly repaired due to the size
or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
■Replacing tires and wheels
If the ID code of the tire press ure warning valve and transmitt er is not reg-
istered, the tire pressure warni ng system will not work properly. A f t e r d r i v -
ing for about 20 minutes, the tire pressure warning light blink s for 1
minute and stays on to indi cate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified techni cian even
if it has seldom or never been u sed or damage is not obvious.
■Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation
pressure checks. Make sure to chec k tire inflation pressure as part of
your routine of daily vehicle checks.
■Maximum load of tire
Check that the number given by dividing the maximum load by 1.1 0 of the
replacement tire is greater than 1/2 of the Gross Axle Weight R atings
(GAWR) of either the front axle or the rear axle, whichever is greater.
For the GAWR, see the Certification
Label. For the maximum load of the tire,
see the load limit at maximum cold tire
inflation pressure mentioned on the
sidewall of the tire. ( P. 5 3 3 )

Tire types
●Summer tires
Summer tires are high-speed performance tires best suited to hi
ghway
driving under dry conditions. Si nce summer tires do not have th e same
traction performance as snow tires, summer tires are inadequate for
driving on snow-covered or icy ro ads. For driving on snow-covered
roads or icy roads, the use of snow tires is recommended. When install-
ing snow tires, be sure to replace all four tires.
●All season tires
All season tires are designed to provide better traction in sno w and to
be adequate for driving in most winter conditions as well as fo r use
year-round. All season tires, however, do not have adequate tra ction
performance compared with snow tires in heavy or loose snow. Al so, all
season tires fall short in acceleration and handling performanc e com-
pared with summer tires in highway driving.
●Snow tires
For driving on snow-covered roads or icy roads, we recommend us ing
snow tires. If you need snow tires, select tires of the same si ze, con-
struction and load capacity as t he originally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construct ion. Do not install studded tires without
first checking local regulations for possible restrictions. Sno w tires
should be install ed on all wheels. ( P. 329)
■If the tread on snow tires wea rs down below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is lost.
■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.

Situations in which the tire pressure warning system may not op
er-
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.
• 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 the spare tire is in a location subject to poor radio wave signal
reception.
• If a large metallic object whic h can interfere with signal reception is
put near the spare tire.
• If tires not equipped with the tire pressure warning valves an d trans-
mitters are used.
• If the ID code on the tire pressure warning valves and transmi tters 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
●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.

When ID code registration has failed
●Registration may take long time or the ID codes may not be regi
stered in
the following situations.
• When the vehicle is moved backward during registration.
Registration is started again from the beginning and it may tak e lon-
ger than usual.
• When another vehicle is running the side of the vehicle such a s in
heavy traffic.
It may take longer to detect the vehicle’ tire pressure warning valves
and transmitters.
• If tire pressure warning valves and transmitters are in the vehicle.
The ID codes may n ot be registered.
●When performing registration, drive on a paved road if possible .
Depending on the driving environment and condition of the tires, regis-
tration will be complet ed in approximately 10 to 30 minutes.
• If registration is not complete after driving approximately 30 minutes,
continue driving for a while.
• If registration is not complete after driving approximately 1 hour, park
the vehicle in a safe place for approximately 20 minutes. Then drive
straight (with occasional left and right turns) at approximatel y 40 km/h
(25 mph) or more
* for approximately 10 to 30 minutes.
If registration is still not comp lete, have the vehicle inspected by your
Toyota dealer.
*: Except when making a left/right turn
●When the tire pressure warning light does not blink slowly 3 ti mes, the
ID code will not be registered and the system will not operate properly.
Perform registration again.
■When registering ID codes
●Initialize the tire pressure war ning system after ID code regis tration. Ini-
tialization is disable d if the system was initialized before re gistration.
●After ID code registration, the tires are hot by driving. Initi alize the tire
pressure warning system af ter the tires become cold.
■Canceling the change wheel set mode
●If turning the engine switch to the “LOCK” position (vehicles w ithout a
smart key system) or off (vehicles with a smart key system) whe n in the
change wheel set mode before driving, the change wheel set mode is
canceled.
●After driving when in the change wheel set mode, the change whe el set
mode cannot be canceled. To cancel the mode, perform the proced ure
for ID code registration again and turn the engine switch to th e “LOCK”
position (vehicles without a smart key system) or off (vehicles with a
smart key system ) before driving.
●If the change wheel set mode is canceled, the ID codes that hav e
already been registered are commu nicated. When communication is fin-
ished, the tir e pressure warning light will turn off.

Maintenance and care
4RUNNER (U)
NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps
●When removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact your Toyota dealer as the tire pres-
sure warning valves and transmitters may be damaged if not hand led
correctly.
●Make sure to install the tire val ve caps. If the tire valve caps are not
installed, water could enter the tire pressure warning valves a nd the
tire pressure warning valves could be bound.
●When replacing tire valve caps, do not use tire valve caps othe r than
those specified. The cap may become stuck.
■To avoid damage to the tire pressure warning valves and transmi t-
ters
When a tire is repaired with liqui d sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sea lant is
used, contact your Toyota dealer or other qualified service shop as soon
as possible. Make sure to replac e the tire pressure warning valve and
transmitter when replacing the tire. ( P. 4 2 5 )
■Driving on rough roads
Take particular care when drivi ng on roads with loose surfaces or pot-
holes.
These conditions may cause losses in tire inflation pressure, reducing
the cushioning ability of the t ires. In addition, driving on ro ugh roads
may cause damage to the tires themselves, as well as the vehicl e’s
wheels and body.
■If tire inflation pressure of e ach tire becomes low while drivi ng
Do not continue driving, or your t ires and/or wheels may be ruined.

Instructions for checking tire inflation pressure
When checking tire inflation p
ressure, 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 than 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 o nly on its appear-
ance.
●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 pre ssure 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 in flated, the following conditions may occur
which could lead to an accident r esulting in death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting from overh eated tires
●Air leaking from between tire and wheel
●Wheel deformation and/or tire damage
●Greater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp ed ges in the road, etc.)
NOTICE
■When inspecting and adjusti ng 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 pressu re.

Maintenance and care
4RUNNER (U)
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim wid th and
inset
*.
Replacement wheels are available at your Toyota dealer.
*:Conventionally referred to as “offset”.
Toyota does not recommend using the following:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that hav e been straightened
● Use only Toyota wheel nuts and wrenches designed for use with
your aluminum wheels.
● When rotating, repairing or changi ng your tires, check that the
wheel nuts are still tight afte r driving 1000 miles (1600 km).
● Be careful not to damage the aluminum wheels when using tire
chains.
● Use only Toyota genuine balance we ights or equivalent and a plas-
tic or rubber hammer when balancing your wheels.
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.
