Wheels
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.
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warn ing
valves and transmitters that allow the tire pressure warning sy stem to
provide advance warning in the event of a loss in tire inflatio n pressure.
Whenever wheels are replaced, tir e pressure warning valves and trans-
mitters must be installed. ( P. 363)
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.

When the tire pressure warning light comes on
Inspect the appearance of the ti
re to check that the tire is not punctured.
If the tire is punctured: P. 436
If the tire is not punctured:
Carry out the following procedure after the tire temperature has lowered
sufficiently.
●Check the tire inflation pressure and adjust to the appropriate level.
●If the warning light does not go out even after several minutes , check
that the tire inflation pressure is at the specified level and carry out ini-
tialization. ( P. 3 6 4 )
The warning light may come on again if the above operations are con-
ducted without first allowing t he tire temperature to lower suf ficiently.
■The tire pressure warning light may come on due to natural caus es
The tire pressure warning light may come on due to natural caus es such
as natural air leaks and tire inflation pressure changes caused by tem-
perature. In this case, adjusting the tire inflation pressure w ill turn off the
warning light (afte r a few minutes).
■When a tire is replace d with a spare tire
The compact spare tire is not equipped with a tire pressure war ning valve
and transmitter. If a tire goes flat, the tire pressure warning light will not
turn off even though the flat tire has been replaced with the s pare tire.
Replace the spare tire with the repaired tire and adjust the ti re inflation
pressure. The tire pressure war ning light will go off after a few minutes.
■Conditions that the tire pressure warning system may not functi on
properly
 P. 3 6 7
■If the tire pressure warning light frequently comes on after bl inking
for 1 minute
If the tire pressure warning light frequently comes on after bl inking for
1 minute when the engine switch is turned to the “ON” position (vehicles
without smart key system) or IGNITION ON mode (vehicles with sm art

WARNING
■If both the ABS and the brake s ystem warning lights remain on
Stop your vehicle in a safe place immediately and contact your To y o t a
dealer. The vehicle will become extremely unstable during braki ng, and the
ABS system may fail, which could cause an accident resulting in death or
serious injury.
■ When the electric power steering system warning light comes on
When the light comes on yellow, the assist to the power steerin g is
restricted. When the light comes on red, the assist to the powe r steering is
lost and handling operations of the steering wheel become extre mely
heavy. When steering wheel operations are heavier than usual, g rip the
steering wheel firmly and operate it using more force than usua l.
■
If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could
cause a loss of vehicle control and result in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust t he tire
inflation pressure immediately.
●If the tire pressure warning light comes on even after tire inf lation pres-
sure adjustment, it is probable that you have a flat tire. Chec k the tires.
If a tire is flat, change it with the spare tire and have the f lat tire
repaired by the nearest Toyota dealer.
●Avoid abrupt maneuvering and braking. If the vehicle tires dete riorate,
you could lose control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.
