If your vehicle needs
to be towed
If towing is necessary, we
recommend having your
vehicle towed by your
Toyota dealer or commer-
cial towing service, using a
wheel-lift type truck or flat-
bed truck.
Use a safety chain system
for all towing, and abide by
all state/provincial and local
laws.
If towing your vehicle with a
wheel-lift type truck, use a
towing dolly. (P.637, 638)
WARNING
Observe the following precau-
tions. Failure to do so may result
in death or serious injury.
■When towing the vehicle
Be sure to transp ort the vehicle
with all four wheels raised off the
ground. If the vehicle is towed
with the tires co ntacting the
ground, the drivetrain or related
parts may be damaged, the vehi-
cle may fly off the truck, or elec-
tricity generated by the operation
of the motor may cause a fire to
occur depending o n the nature of
the damage or malfunction.
■While towing (vehicles with
towing eyelet)
●When towing using cables or
chains, avoid sudden starts, etc.
which place excessive stress on
the towing eyelets, cables or
chains. The towing eyelets,
cables or chains may become
damaged, broken debris may hit
people, and cause serious dam-
age.
●Do not turn the power switch to
OFF.
There is a possi bility that the
steering wheel is locked and
cannot be operated.

■If the malfunction indicator
lamp comes on while driving
First check the following:
●Is the fuel t ank empty?
If it is, fill the fuel tank immediately.
●Is the fuel tank cap loose?
If it is, tighten it securely.
The light will go o ff after several
driving trips.
If the light does not go off even after
several trips, contact your Toyota
dealer as soon as possible.
■Electric power steering system
warning light (warning buzzer)
When the 12-volt battery charge
becomes insufficien t or the voltage
temporarily drops, the electric power
steering system warning light may
come on and the warning buzzer
may sound.
■When the tire pressure warning
light comes on ( vehicles with
tire pressure warning system)
Inspect the tires to check if a tire is
punctured.
If a tire is punctured: P.658
If none of the tires are punctured:
Turn the power switch to OFF then
turn it to ON.
Check if the tire pressure warning
light comes on or blinks.
If the tire pressur e 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 pressur e 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.600)
■The tire pressure warning light
may come on due to natural
causes (vehicles with tire pres-
sure 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 ca se, adjusting the
tire inflation pressure will turn off the
warning ligh t (after a few minutes).
■When a tire is replaced with a
compact spare tire (vehicles
with tire pressure warning sys-
tem)
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 o ff even though the
flat tire has been replaced with the
spare tire. Replace the spare tire
with the standard 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
tire pressure warning system)

WARNING
■If a warning light comes on or
a warning buzzer sounds
when a warning message is
shown on the multi-informa-
tion display
*
Check and follow the message
shown on the multi-information
display.
Failure to do so m ay result in
death or serious injury.
*: Warning lights illuminate in red
or yellow and the warning
buzzer beeps on ce or sounds
continuously.
WARNING
■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 assist to the power
steering is lost and handling oper-
ations of the steering wheel
become extremely heavy.
If the steering wheel becomes
heavier than usual when operat-
ing, hold firmly a nd operate using
more force than usual.
■If the tire pr essure warning
light comes on ( vehicles with
tire pressure warning system)
Be sure to observe the following
precautions. Failure to do so
could cause a loss of vehicle con-
trol and result in death or serious
injury.
●Stop your vehicle in a safe
place as soon as possible.
Adjust the tire inflation pressure
immediately.
●If the tire pressure warning light
comes on even after tire infla-
tion 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 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 (vehi-
cles with tire pressure warn-
ing system)
The tire pressure warning system
may not activate immediately.

6528-2. Steps to take in an emergency
■Maintenance of the tires
(vehicles with tire pressure
warning system)
Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recom-
mended by the vehicle manufac-
turer on the vehicle placard or tire
inflation pressure label (tire and
load information label). (If your
vehicle has tires of a different size
than the size indicated on the
vehicle placard or tire inflation
pressure label [tire and load infor-
mation label], you should deter-
mine the proper tire inflation
pressure for those tires.)
As an added safe ty feature, your
vehicle has been equipped with a
tire pressure m onitoring system
(TPMS-tire pressure warning sys-
tem) that illumina tes a low tire
pressure telltale (tire pressure
warning light) when one or more
of your tires is significantly under-
inflated. Accordingly, when the
low tire pressure telltale (tire pres-
sure warning light) illuminates,
you should stop and check your
tires as soon as possible, and
inflate them to the proper pres-
sure. Driving on a significantly
under-inflated tire causes the tire
to overheat and can lead to tire
failure. Under-inflation also
reduces fuel efficiency and tire
tread life, and may affect the vehi-
cle’s handling and stopping abil-
ity.WARNING
Please note that the TPMS (tire
pressure warning system) is not a
substitute for proper tire mainte-
nance, and it is the driver’s
responsibility to m aintain correct
tire pressure, even if under-infla-
tion has not reached the level to
trigger illuminati on of the TPMS
low tire pressure te lltale (tire pres-
sure warning light).
Your vehicle has also been
equipped with a TPMS (tire pres-
sure warning system) malfunc-
tion indicator to indicate when the
system is not operating properly.
The TPMS (tire pressure warning
system) malfunction indicator is
combined with the low tire pres-
sure telltale (tire pressure warning
light). When the system detects a
malfunction, the te lltale will flash
for approximately one minute and
then remain continuously illumi-
nated. This sequence will con-
tinue upon subsequent vehicle
start-ups as long as the malfunc-
tion exists. When the malfunction
indicator is illu minated, the sys-
tem may not be ab le to detect or
signal low tire pressure as
intended.
TPMS (tire pressure warning sys-
t em ) m alf un ctio n s m a y o cc ur f or 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
warning system) malfunction tell-
tale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow
the TPMS (tire pressure warning
system) to continue to function
properly.

contact surface, the wheel nuts
may loosen while the vehicle is in
motion, causing the tire to come off.
2 Install the spare tire and
loosely tighten each wheel
nut by hand by approximately
the same amount.
When replacing an aluminum wheel
with a steel whee l, tighten the
wheel nuts until the tapered portion
( ) comes into loose contact with
the disc wheel seat ( ).
When replacing an aluminum wheel
with an aluminum wheel, turn the
wheel nuts until the washers ( )
come into contact with the disc
WARNING
■Replacing a flat tire
●Do not touch the disc wheels or
the area around the brakes
immediately after the vehicle
has been driven.
After the vehicle has been
driven the disc wheels and the
area around the brakes will be
extremely hot. Touching these
areas with hands , feet or other
body parts while changing a tire,
etc. may result in burns.
●Failure to follow these precau-
tions could cause the wheel
nuts to loosen and the tire to fall
off, resulting in death or serious
injury.
• Have the wheel nuts tightened with a torque wrench to 76 ft•lbf
(103 N•m, 10.5 kgf•m) as soon
as possible after changing
wheels.
• When installing a tire, only use wheel nuts that have been spe-
cifically designed for that wheel.
• If there are any cracks or defor-
mations in the bolt screws, nut
threads or bolt holes of the
wheel, have the vehicle
inspected by your Toyota
dealer.
• When installing the wheel nuts,
be sure to install them with the
tapered ends facing inward.
●For vehicles with power back
door: In cases such as when
replacing tires, make sure to
turn off the power back door
system ( P.146). Failure to do
so may cause the back door to
operate unintentionally if the
power back door switch is acci-
dentally touched, resulting in
hands and fingers being caught
and injured.
