■To prevent malfunctions and
data corruptions
●When charging, bringing a
credit, or other magnetic card,
or magnetic storage media
close to the charge area may
clear any stored data due to
magnetic influence. Also, do not
bring a wristwatch or other pre-
cision instrument close to the
charge area since doing so may
cause it to malfunction.
●Do not charge with a non-con-
tact IC card such as a transpor-
tation system IC card inserted
between the charging side of a
portable device and the charge
area. The IC chip may become
extremely hot and damage the
portable device or IC card. Be
especially careful not to charge
a portable device inside a case
or cover with a non-contact IC
card attached.
●Do not leave portable devices
inside the vehicle. The inside of
the vehicle can become hot in
extreme heat, which could
cause a malfunction.

been updated
If the smartphone OS has been
updated to a new er version, its
charging specifications may have
changed significantly. For details,
check the information on the man-
ufacturer’s website.

3647-2. Steps to take in an emergency
system warning light may come on
and the warning buzzer may sound.
■When the tire pressure warning
light comes on (vehicles with a
tire pressure warning system)
Inspect the tires to check if a tire is
punctured.
If a tire is punctured: P.370
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 your Toyota
dealer immediately.
If the tire pressure warning light
comes on
1 After the temperature of the tires
has lowered sufficiently, check
the inflation 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 specified level and perform
initialization. ( P.318)
■The tire pressure warning light
may come on due to natural
causes (vehicles with a tire
pressure warning system)
The tire pressure warning light may
come on due to natural causes such
as natural air leaks and tire inflation
pressure changes caused by tem-
perature. 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 (vehicl es with a tire
pressure warning system)
The compact spare tire is not
equipped with a tire pressure warn-
ing 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
spare tire. Replace the spare tire
with the repaired tire and adjust the
tire inflation pressure. The tire pres-
sure warning light will go off after a
few minutes.
■Conditions that the tire pres-
sure warning system may not
function properly (vehicles with
a tire pressure warning system)

WARNING
■If both the ABS and the brake
system warning lights remain
on
Stop your vehicle in a safe place
immediately and contact your Toy-
ota dealer.
The vehicle will become
extremely unstable during brak-

which could cause an accident
resulting in death o r serious injury.
■When the electric power
steering 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 assis t to the power
steering is lost and handling oper-
ations 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 fo rce than usual.
■If the tire pressure warning
light comes on ( vehicles with
a tire pressure warning sys-
tem)
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.

WARNING
TPMS (tire pressure warning sys-
tem) malfunctions may occur for a
variety of reasons, including the
installation of replacement or
alternate tires or wheels on the
vehicle that prevent the TPMS
(tire pressure warning system)
from functioning properly. Always
check the TPMS (tire pressure

tale after replacing one or more
tires or wheels on your vehicle to
ensure that the r eplacement or
alternate tires and wheels allow
the TPMS (tire pressure warning
system) to continue to function
properly.
