Tire inflation pressure
Check the pressure with a gauge ev-
ery two weeks, or at least once a
month. See page 391 in Section 7 −2
for additional information.
Tire surface and wheel nuts
Check the tires carefully for cuts,
damage or excessive wear. See page
393 in Section 7− 2 for additional in-
formation. When checking the tires,
make sure no nuts are missing, and
check the nuts for looseness. Tighten
them if necessary.
Tire rotation
Rotate the tires according to the
maintenance schedule. (For sched-
uled maintenance information, please
refer to the “Scheduled Maintenance
Guide” or “Owner ’s Manual Supple-
ment”.) See page 395 in Section 7 −2
for additional information.Be on the alert for changes in perfor-
mance, sounds, and visual tip −offs that
indicate service is needed. Some impor-
tant clues are as follows:
Engine missing, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A leak under the vehicle (however, wa-
ter dripping from the air conditioning
after use is normal.)
Change in exhaust sound (This may
indicate a dangerous carbon monoxide
leak. Drive with the windows open and
have the exhaust system checked im-
mediately.)
Flat −looking tire; excessive tire squeal
when cornering; uneven tire wear
Vehicle pulls to one side when driving
straight on a level road
Strange noises related to suspension
movement
Loss of brake effectiveness; spongy
feeling brake pedal; pedal almost
touches floor; vehicle pulls to one side
when braking
Engine coolant temperature continually
higher than normal If you notice any of these clues, take your
vehicle to your Toyota dealer as soon as
possible. It probably needs adjustment or
repair.
CAUTION
Do not continue driving with the ve-
hicle unchecked. It could result in se-
rious vehicle damage and possibly
personal injury.

CAUTION
Never touch, remove or disassemble
high voltage parts and cables.
Touching, removing or disassem-
bling those parts and cables can
cause severe burns or electric
shock that may result in death or
serious injury. For the locations of
high voltage parts and cables, see
“—High voltage components” on
page 6 in Section 11.
When the hybrid system is on, keep
hands, clothing, and tools away
from the moving fan. (Removing
rings, watches, and ties is advis-
able.)
Right after driving, the engine
compartment—the engine, radiator,
exhaust manifold and spark plug
boots, etc.—will be hot. So be care-
ful not to touch them. Oil, fluids
and spark plugs may also be hot.
If the radiator is hot, do not remove
the radiator cap or loosen the drain
plugs to prevent burning yourself.
Do not leave anything that may
burn easily, such as paper or rags,
in the engine compartment.
Do not smoke, cause sparks or al-
low open flames around fuel or the
battery. Their fumes are flammable.
When the hybrid system is operat-
ing with the “READY” light on, the
engine may suddenly start in some
cases. When you inspect the engine
compartment, be sure to turn off
the hybrid system.
Do not get under your vehicle with
just the body jack supporting it. Al-
ways use automotive jack stands or
other solid supports.
Be sure that the ignition is off if
you work near the electric cooling
fans or radiator grille. With the
ignition on, the electric cooling fans
will automatically start to run if the
engine coolant temperature is high
and/or the air conditioning is on.
Use eye protection whenever you
work on or under your vehicle
where you may be exposed to flying
or falling material, fluid spray, etc.
Brake fluid can harm your hands or
eyes and damage painted surfaces.
If fluid gets on your hands or in
your eyes, flush the affected area
with clean water immediately. If you
still feel uncomfortable with your
hands or eyes, go to the doctor.
Used engine oil contains potentially
harmful contaminants which may
cause skin disorders such as in-
flammation or skin cancer, so care
should be taken to avoid prolonged
and repeated contact with it. To re-
move used engine oil from your
skin, wash thoroughly with soap
and water.
Do not leave used oil within the
reach of children.
Dispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and fil-
ter in household trash, in sewers or
onto the ground. Call your dealer or
a service station for information
concerning recycling or disposal.
Be extremely cautious when work-
ing on the auxiliary battery. It con-
tains poisonous and corrosive
sulfuric acid.

High tire pressure (overinfla-
tion)—
Poor handling
 Excessive wear
 Uneven wear
 A greater possibility of tire
damage from road hazardsTread wear indicator
CHECKING YOUR TIRES
Check the tire’s tread for tread
wear indicators. If the indicators
show, replace the tires. The loca-
tion of tread wear indicators is
shown by the “TWI” or “
Δ” marks,
etc., molded on the sidewall of
each tire. The tires on your Toyota have built
−in
tread wear indicators to help you
know when the tires need replace-
ment. When the tread depth wears to
1.6 mm (0.06 in.) or less, the indica-
tors will appear. If you can see the
indicators in two or more adjacent
grooves, the tire should be replaced.
The lower the tread, the higher the
risk of skidding.
Depending on driving conditions, your
tires may wear more rapidly than
those of conventional vehicles.
The effectiveness of snow tires is
lost if the tread wears down below
4 mm (0.16 in.).
If you have tire damage such as
cuts, splits, cracks deep e nough to
expose the fabric, or bulges indi-
cating internal damage, the tire
should be repl aced.
If a tire often goes flat or cannot be
properly repaired due to the size or
location of a cut or other damage, it
should be replaced. If you are not
sure, consult with your Toyota dealer.

All wheel drive models:
Do not use tires of different
brands, sizes, construction or
tread patterns, as this may
cause dangerous handling
characteristics resulting in
loss of control.
Toyota recommends all four tires,
or at least both of the front or rear
tires be replaced at a time as a set.
See “If you have a flat tire” on page
344 in Section 4 for tire change proce-
dure.
When a tire is replaced, the wheel
should always be balanced.
An unbalanced wheel may affect ve-
hicle handling and tire life. Wheels
can get out of balance with regular
use and should therefore be balanced
occasionally.
When replacing a tubeless tire, the
air valve should also be repl aced
w i t h a new on e.
To equalize tire wear and help ex-
tend tire life, Toyota recommends
that you rotate your tires accord-
ing to the maintenance schedule.
(For scheduled maintenance infor-
mation, please refer to the “Sched-
uled Maintenance Guide” or “Own-
er’s Manual Supplement”.)
However, the most appropriate tim-
ing for tire rotation may vary ac-
cording to your driving habits and
road surface conditions.
See “If you have a flat tire” on page
344 in Section 4 for tire change proce-
dure. When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out
−
of −balance wheels, or severe braking.
