Maintenance and care
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:
z Wheels of different sizes or types
z Used wheels
z 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.333)
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
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.

■Tire pressure warning light
■LTA indicator* (warning buzzer)
*: This light illuminates on the multi-information display.
■Stop & Start cancel indicator (warning buzzer)
Warning lightDetails/Actions
When the light comes on after blinking for approximately 1 minute
(a buzzer does not sounds):
Malfunction in the tire pressure warning system
→ Have the system checked by any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer.
When the light comes on (a buzzer sounds):
Low tire inflation pressure from natural causes
→ Adjust the tire inflation pressure to the specified cold tire
inflation pressure level. ( →P.417)
Low tire inflation pressure from flat tire
→ Immediately stop the vehicle in a safe place.
Handling method ( →P.375)

When trouble arises
ble.
■Electric power steering system
warning light (warning buzzer)
When the battery charge becomes insufficient or the voltage temporarily
drops, the electric power steering sys- tem warning light may come on and the warning buzzer may sound.
■When the tire pressure warning
light comes on
Inspect the tires to check if a tire is punctured.
If a tire is punctured: →P.379, 389
If none of the tires are punctured: Turn the engine switch off then turn it to
ON. Check if the tire pressure warning light comes on or blinks.
If the tire pressure warning light blinks
for approximately 1 minute then stays on
There may be a malfunction in the tire
pressure warning system. Have the vehicle inspected by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer immedi- ately.
If the tire pressure warning light
comes on
1 After the temperature of the tires has lowered sufficiently, check the infla-tion pressure of each tire and adjust
them to the specified level.
2 If the warning light does not turn off even after several minutes have elapsed, check that the inflation
pressure of each tire is at the speci- fied level and perform initialization. ( →P.334)
■The tire pressure warning light may
come on due to natural causes
The tire pressure warning light may come on due to natural causes such as
natural air leaks and tire inflation pres- sure changes caused by temperature. In this case, adjusting the tire inflation
pressure will turn off the warning light (after a few minutes).
■When a tire is replaced with a spare
tire
Vehicles with a compact spare tire: The compact spare tire is not equipped with
a tire pressure warning valve and trans- mitter. If a tire goes flat, the tire pressure warning light will not turn off even
though the flat tire has been replaced with the spare tire. Replace the spare tire with the repaired tire and adjust the
tire inflation pressure. The tire pressure warning light will go off after a few min-utes.
Vehicles with a full-size spare tire: The spare tire is also equipped with a tire pressure warning valve and transmitter.
The tire pressure warning light will turn on if the tire inflation pressure of the spare tire is low. If a tire goes flat, the
tire pressure warning light will not turn off even though the flat tire has been replaced with the spare tire. Replace the
spare tire with the repaired tire and adjust the tire inflation pressure. The tire pressure warning light will go off after a
few minutes.
■Conditions that the tire pressure warning system may not function properly
→ P. 3 3 3
WARNING
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact any autho-rized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer. The vehicle will become extremely unstable during braking, and the ABS
system may fail, which could cause an accident resulting in death or seri-ous injury.

7-2. Steps to take in an emergency
WARNING
■When the electric power steer- ing system warning light comes
on
When the light comes on yellow, the assist to the power steering is
restricted. When the light comes on red, the assist to the power steering is lost and handling operations of the
steering wheel become extremely heavy.When steering wheel operations are
heavier than usual, grip the steering wheel firmly and operate it using more force than usual.
■If the tire pressure warning light comes on
Be sure to observe the following pre- cautions.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 the tire inflation pressure immediately.
●Vehicles with a compact spare tire and full-size spare tire: If the tire
pressure warning light comes on even after tire inflation pressure adjustment, it is probable that you
have a flat tire. Check the tires. If a tire is flat, change it with the spare tire and have the flat tire repaired
by the nearest any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Vehicles with emergency tire punc-ture repair kit: If the tire pressure
warning light comes on even after tire inflation pressure adjustment, it is probable that you have a flat tire.
Check the tires. If a tire is flat, repair the flat tire by using emergency tire puncture repair kit.
●Avoid abrupt maneuvering and braking.If the vehicle tires deteriorate, you
could lose control of the steering wheel or the brakes.
■If a blowout or sudden air leak-age should occur
The tire pressure warning system
may not activate immediately.
NOTICE
■To ensure the tire pressure warn- ing system operates properly
Do not install tires with different speci- fications or makers, as the tire pres-sure warning system may not operate
properly.
