■How to change between wheel
sets
1 Have the vehicle fitted with the
preferred wheel set.
2 Press / (7-inch display)
or / (4.2-inch display) of
the meter control switch to
select .
3 Press / (7-inch display)
or / (4.2-inch display) to
select “Vehicle Settings” and
then press .
4 Press / to select “TPWS
setting” and then press .
5 Press / to select “Identi-
fying Each Wheel & Position”.
Then press and hold until
the tire pressure warning light
blinks slowly 3 times. Afterward,
turns on after flashing for 1 min-
ute.
After 2 minutes, registration of a second
wheel set is being performed and the
tire pressure warning light will turn off.
6 Initialize the tire pressure warn-
ing system. ( P.367)
If the tire inflation pressure settings for
the installed tire changes, initialization operations are required, but if the same tire inflation pressure, initialization is
not required.
7 Drive straight (with occasional
left and right turns) at approxi-
mately 40 km/h (25 mph) or
more for approximately 10 to 30
minutes.
Registration of a second wheel set is complete when the tire pressure warn-ing light turns off and the inflation pres-
sure of each tire is displayed on the multi-information display.

Maintenance and care
Tire inflation pressure is specified
on the label on the driver’s side
door frame as shown.
Left-hand drive vehicles
Right-hand drive vehicles
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pres- sure may result in the following:
●Reduced safety
●Damage to the drivetrain
●Reduced tire life due to wear
●Reduced fuel economy
●Reduced driving comfort and poor
handling
If a tire needs frequent inflating, have it checked by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
■Instructions for checking tire infla-tion pressure
When checking tire inflation pressure, 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 1.5 km or 1 mile, 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 pres-
sure to be higher after driving as heat is generated in the tire. Do not reduce
tire inflation pressure after driving.
●Passengers and luggage weight
should be placed so that the vehicle is balanced.
Tire inflation pressure
Make sure to maintain proper
tire inflation pressure. Tire
inflation pressure should be
checked at least once per
month. However, Toyota rec-
ommends that tire inflation
pressure be checked once
every two weeks. ( P.454)

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 serious injury:
●Excessive wear

6-3. Do-it-yourself maintenance
When replacing wheels, care
should be taken to ensure that they
are equivalent to those removed in
load capacity, diameter, rim width
and inset*.
Replacement wheels are available
at any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
*: Conventionally referred to as offset.
Toyota does not recommend using
the following:
 Wheels of different sizes or types
 Used wheels
 Bent wheels that have been
straightened
■When replacing wheels
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 pressure. Whenever wheels are replaced, the tire pressure warning valves and transmitters must be
installed. ( P.366)
WARNING
●Uneven wear
●Poor handling
●Possibility of blowouts resulting
from overheated tires
●Air leaking from between tire and
wheel
●Wheel deformation and/or tire dam-
age
●Greater possibility of tire damage
while driving (due to road hazards, expansion joints, sharp edges on the road, etc.)
NOTICE
■When inspecting and adjusting tire inflation pressure
B e s ur e t o pu t th e t i r e v al ve ca ps ba ck
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.

Maintenance and care
■When removing the wheel orna-
ment (vehicles with an emergency tire puncture repair kit)
Remove the wheel ornament using the
wheel cap clip*.*: The wheel cap clip is installed in the
glove box. ( P.327)
Use only Toyota wheel nuts and
wheel nut wrenches designed for
use with your aluminum wheels.
WARNING
■When replacing wheels
●Do not use wheels that are a differ- ent size from those recommended in the Owner’s Manual, as this may
result in a loss of handling control.
●Never use an inner tube in a leak-
ing wheel which is designed for a tubeless tire.Doing so may result in an accident,
causing death or serious injury.
■When installing the wheel nuts
●Be sure to install the wheel nuts with the tapered ends facing inward ( P.431). Installing the nuts with
the tapered ends facing outward can cause the wheel to break and eventually cause the wheel to come
off while driving, which could lead to an accident resulting in death or serious injury.
●Never use oil or grease on the wheel bolts or wheel nuts.Oil and grease may cause the
wheel nuts to be excessively tight- ened, leading to bolt or disc wheel damage. In addition, the oil or
grease can cause the wheel nuts to loosen and the wheel may fall off, causing an accident and resulting in
death or serious injury. Remove any oil or grease from the wheel bolts or wheel nuts.
■Use of defective wheels prohib-ited
Do not use cracked or deformed wheels. Doing so could cause the tire to leak air during driving, possibly
causing an accident.
NOTICE
■Replacing tire pressure warning valves and transmitters
●Because tire repair or replacement may affect the tire pressure warning valves and transmitters, make sure
to have tires serviced by any autho- rized Toyota retailer or Toyota authorized repairer, or any reliable
repairer. In addition, make sure to purchase your tire pressure warn-ing valves and transmitters at any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly with non-genuine wheels.

 Be careful not to damage the
aluminum wheels when using
tire chains.
 Use only Toyota genuine balance
weights or equivalent and a plas-
tic or rubber hammer when bal-
ancing your wheels.
