WARNING
The engine compartment contains
many mechanisms and fluids that
may move suddenly, become hot,
or become electrically energized.
To avoid death or serious injury,
observe the following precautions.
ItemsParts and tools■When working on the engine
compartment
●Make sure that the “ACCES-
SORY” or “IGNITION ON” on
the multi-information display
and the “READY” indicator are
both off.
●Be careful not to touch the
engine, power control unit, radi-
ator, exhaust manifold, etc. right
after driving as they may be hot.
Oil and other fluids may also be
hot.
●Do not leave anything that may
burn easily, such as paper and
rags, in the engine compart-
ment.
●Do not smoke, cause sparks or
expose an open flame to fuel.
Fuel fumes are flammable.
■When working near the elec-
tric cooling fan or radiator
grille
Be sure the power switch is off.
With the power switch in ON, the
electric cooling fa n may automati-
cally start to run if the air condi-
tioning is on and/or the coolant
temperature is high. ( P.417)
■Safety glasses
Wear safety glasses to prevent
flying or falling material, fluid
spray, etc. from getting in your
eyes.
NOTICE
■If you remove the air cleaner
filter
Driving with the air cleaner filter
removed may cause excessive
engine wear due to dirt in the air.

4226-3. Do-it-yourself maintenance
Check if the treadwear indica-
tors are showing on the tires.
Also check the tires for uneven
wear, such as excessive wear
on one side of the tread.
Check the spare tire condition
and pressure if not rotated.
New tread
Worn tread
Treadwear indicator
The location of treadwear indicators
is shown by a “TWI” or “ ” mark, etc., molded into the sidewall of
each tire.
Replace the tires if the treadwear
indicators are s
howing on a tire.
■When to replace your vehicle’s
tires
Tires should be replaced if:
●The treadwear indicators are
showing on a tire.
●You have tire damage such as
cuts, splits, cracks deep enough
to expose the fabric, and bulges
indicating internal damage.
●A tire goes flat repeatedly or can-
not be properly repaired due to the
size or location of a cut or other
damage.
If you are not sure, consult with your
Toyota dealer.
■Tire life
Any tire over 6 years old must be
checked by a qualified technician
even if it has seldom or never been
used or damage is not obvious.
■Proper storage of the spare tire
As an improperly s tored spare tire
may cause damage to the wire
cable that holds i t, check that the
spare tire is stored properly on a
daily basis.
●If the stored spare tire appears to
be slanted or ratt les while driving,
the spare tire may not be properly
stored. Store the spare tire again
by performing the following tire
change procedure correctly:
Tires
Replace or rotate tires in
accordance with mainte-
nance schedules and tread-
wear.

Maintenance and care
1If the spare tire is slanted, the
hoist assembly may be stuck in
the wheel opening. If the spare
tire rattles while driving, it may
not be fully raised. Lower the
spare tire to the ground and
make sure that the hoist assem-
bly is perpendicular to the wheel
opening.
2 Raise the tire slowly and steadily
until a click is heard and the jack
handle skips.
If the spare tire c annot be lowered,
the wire cable may be severed.
Have the vehicle i nspected at your
Toyota dealer.
■Maximum load of tire
Check that the number given by
dividing the maximum load by 1.10
of the replacement tire is greater
than 1/2 of the Gross Axle Weight
Ratings (GAWR) of either the front
axle or the rear a xle, whichever is
greater.
For the GAWR, see the Certification
Label.
For the maximum load of the tire,
see the load limit at maximum cold
tire inflation press ure mentioned on
the sidewall of the tire. ( P.518)
■Tire types
●Summer tires
Summer tires are high-speed perfor-
mance tires best suited to highway
driving under dry conditions. Since
summer tires do not have the same
traction performanc e as snow tires,
summer tires are inadequate for driving on snow-covered or icy
roads. For driving on snow-covered
roads or icy roads, the use of snow
tires is recommended. When install-
ing snow tires, be sure to replace all
four tires.
●All season tires
All season tires are designed to pro-
vide better traction in snow and to
be adequate for driving in most win-
ter conditions as well as for use
year-round. All se ason tires, how-
ever, do not have adequate traction
performance compared with snow
tires in heavy or loose snow. Also,
all season tires fall short in accelera-
tion and handling performance com-
pared with summer tires in highway
driving.
●Snow tires
For driving on snow-covered roads
or icy roads, we recommend using
snow tires. If you need snow tires,
select tires of the same size, con-
struction and load capacity as the
originally installed tires. Since your
vehicle has radial tires as original
equipment, make sure your snow
tires also have radi al construction.
Do not install studded tires without
first checking local regulations for
possible restrictions. Snow tires
should be installed on all wheels.
(  P.330)
■If the tread on snow tires wears
down below 0.16 in. (4 mm)
The effectiveness of the tires as
snow tires is lost.

4246-3. Do-it-yourself maintenance
Rotate the tires in the order
shown.
Front
To equalize tire w ear and extend
tire life, Toyota recommends that
tire rotation is carried out at the
same interval as tire inspection.
Do not fail to initialize the tire pres-
sure warning system after tire rota-
tion.
Your vehicle is equipped with a
tire pressure warning system
that uses tire pressure warning
valves and transmitters to detect
low tire inflation pressure before
serious problems arise.
 The tire pressure detected by
the tire pressure warning sys-
tem can be displayed on the
WARNING
■When inspecting or replacing
tires
Observe the following precautions
to prevent accidents.
Failure to do so may cause dam-
age to parts of t he drive train as
well as dangerous handling char-
acteristics, which may lead to an
accident resulting in death or seri-
ous injury.
●Do not mix tires of different
makes, models or tread pat-
terns.
Also, do not mix tires of remark-
ably different treadwear.
●Do not use tire sizes other than
those recommended by Toyota.
●Do not mix differently con-
structed tires (radial, bias-belted
or bias-ply tires).
●Do not mix summer, all season
and snow tires.
●Do not use tires that have been
used on another vehicle.
Do not use tires if you do not
know how they were used previ-
ously.
●Do not tow if your vehicle has a
compact spare tire installed.
NOTICE
■Driving on rough roads
Take particular care when driving
on roads with loose surfaces or
potholes.
These conditions may cause
losses in tire inf lation pressure,
reducing the cushio ning ability of
the tires. In addit ion, driving on
rough roads may cause damage
to the tires themselves, as well as
the vehicle’s wheels and body.
■If tire inflation pressure of
each tire becomes low while
driving
Do not continue driving, or your
tires and/or wheels may be
ruined.

■Routine tire inflation pressure
checks
The tire pressure warning system
does not replace routine tire inflation
pressure checks . Make sure to
check tire inflation pressure as part
of your routine o f daily vehicle
checks.
■Situations in which the tire
pressure warning system may
not operate properly
●In the following cases, the tire
pressure warning system may not
operate properly.
• If non-genuine Toyota wheels are
used.
• A tire has been replaced with a
tire that is not an OE (Original
Equipment) tire.
• A tire has been replaced with a
tire that is not of the specified size.
• Tire chains, etc. are equipped.
• An auxiliary-support ed run-flat tire
is equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on

4266-3. Do-it-yourself maintenance
the vehicle, particularly around the
wheels or wheel housings.
• If the tire inflation pressure is
extremely higher than the speci-
fied level.
• If wheel without the tire pressure
warning valve and transmitter is
used.
• If the ID code on the tire pressure
warning valves and transmitters is
not registered in the tire pressure
warning computer.
●Performance may be affected in
the following situations.
• Near a TV tower, electric power plant, gas station, radio station,
large display, airpo rt or other facil-
ity that generates strong radio
waves or electrical noise
• When carrying a portable radio,
cellular phone, cordless phone or
other wireless communication
device
●If tire position information is not
correctly displayed due to the
radio wave conditions, the display
may be corrected by driving and
changing the radio wave condi-
tions.
●When the vehicle is parked, the
time taken for the warning to start
or go off could be extended.
●When tire inflation pressure
declines rapidly for example when
a tire has burst, the warning may
not function.
■Warning performance of the tire
pressure warning system
The warning of the tire pressure
warning system will change in
accordance with th e conditions
under which it was initialized. For
this reason, the system may give a
warning even if the tire pressure
does not reach a low enough level,
or if the pressure is higher than the
pressure that was adjusted to when
the system was initialized.

4286-3. Do-it-yourself maintenance
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure
warning computer and the tire
pressure warning system must
be initialized. Have tire pressure
warning valves and transmitter
ID codes registered by your Toy-
ota dealer. (P.431)
■Replacing tires and wheels
If the ID code of the tire pressure
warning valve and transmitter is not
registered, the tire pressure warning
system will not work properly. After
driving for about 20 minutes, the tire
pressure warning light blinks for 1
minute and stays on to indicate a
system malfunction.
■The tire pressure warning
system must be initialized
in the following circum-
stances:
 When the tire inflation pres-
sure is changed such as
when changing traveling
speed.
 When the tire inflation pres-
sure is changed such as
when the tire size is changed.
 When rotating the tires.
 After registering the ID codes.
( P.431)
When the tire pressure warning
system is initialized, the current
tire inflation pressure is set as
the benchmark pressure.
NOTICE
■Repairing or replacing tires,
wheels, tire pressure warn-
ing valves, transmitters and
tire valve caps
●When removing or fitting the
wheels, tires or the tire pressure
warning valves and transmit-
ters, contact your Toyota dealer
as the tire pr essure warning
valves and transmitters may be
damaged if not handled cor-
rectly.
●Make sure to install the tire
valve caps. If the tire valve caps
are not installed, water could
enter the tire pressure warning
valves and the tire pressure
warning valves could be bound.
●When replacing ti re valve caps,
do not use tire valve caps other
than those specified. The cap
may become stuck.
■To avoid damage to the tire
pressure warning valves and
transmitters
When a tire is repa ired with liquid
sealants, the tire pressure warn-
ing valve and transmitter may not
operate properly. If a liquid seal-
ant is used, contact your Toyota
dealer or other qualified service
shop as soon as possible. Make
sure to replace the tire pressure
warning valve and transmitter
when replacing the tire. ( P.427)
