■Engine oil consumption
A certain amount of engine oil will
be consumed while driving. In the
following situatio ns, oil consump-
tion may increase, and engine oil
may need to be ref illed in between
oil maintenance intervals.
●When the engine is new, for
example directly after purchasing
the vehicle or after replacing the
engine
●If low quality oil or oil of an inap-
propriate viscosity is used
●When driving at high engine
speeds or with a heavy load,
when towing, or when driving
while accelerating o r decelerating
frequently
●When leaving the engine idling for
a long time, or wh en driving fre-
quently through heavy traffic
The coolant level is satisfactory
if it is between the “FULL” and
“LOW” lines on the reservoir
when the hybrid system is cold.
■Engine coolant reservoir
WARNING
■Used engine oil
●Used engine oil contains poten-
tially harmful contaminants
which may cause skin disorders
such as inflammation and skin
cancer, so care should be taken
to avoid prolonged and
repeated contact. To remove
used engine oil from your skin,
wash thoroughly with soap and
water.
●Dispose of used oil and filters
only in a safe an d acceptable
manner. Do not dispose of used
oil and filters in household trash,
in sewers or onto the ground.
Call your Toyota dealer, service
station or auto parts store for
information concerning recy-
cling or disposal.
●Do not leave used engine oil
within the rea ch of children.
NOTICE
■To prevent serious engine
damage
Check the oil le vel on a regular
basis.
■When replacing the engine oil
●Be careful not to spill engine oil
on the vehicle components.
●Avoid overfilling, or the engine
could be damaged.
●Check the oil level on the dip-
stick every time you refill the
vehicle.
●Be sure the engine oil filler cap
is properly tightened.
■If oil is spilled on the engine
cover
To prevent the engine cover from
being damaged, remove any
engine oil from the engine cover
as soon as possible using a neu-
tral detergent. Do not use an
organic solvent such as brake
cleaner.

■If the tread on snow tires wears
down below 0.16 in. (4 mm)
The effectiveness of the tires as
snow tires is lost.
Rotate the tires in the order
shown.
To equalize tire wear 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.

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 recommende d 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 inflation pressure,
reducing the cushioning ability of
the tires. In addition, 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 of daily vehicle
checks.
■Tire inflation pressure
●It may take a few minutes to dis-
play the tire inflation pressure
after the power switch is turned to
ON. It may also take a few min-
utes to display the tire inflation
pressure after inflation pressure
has been adjusted.
●Tire inflation p ressure changes
with temperature.
The displayed values may also be
different from th e values mea-
sured using a tire pressure gauge.
■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-supported 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 the vehicle, particularly around the
wheels or wheel housings. • If the tire inflation pressure is
extremely higher than the speci-
fied level.
• If wheel withou t tire pressure
warning valves and transmitters
are 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 w ill change in
accordance with the conditions
under which it was initialized. For
this reason, the system may give a
warning even if th e 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.

WARNING
■Battery precautions
Observe the following precau-
tions.
Failure to do so m ay result in
death or serious injury.
●Do not swallow the battery.
Doing so may cause chemical
burns.
●A coin battery or button battery
is used in the electronic key. If a
battery is swallowed, it may
cause severe chemical burns in
as little as 2 hours and may
result in death or serious injury.
●Keep away new and removed
batteries from children.
●If the cover cannot be firmly
closed, stop using the electronic
key and stow the key in the
place where children cannot
reach, and then contact your
Toyota dealer.
●If you accidentally swallow a
battery or put a b attery into a
part of your body, get emer-
gency medical attention imme-
diately.
■To prevent battery explosion
or leakage of flammable liq-
uid or gas
●Replace the battery with a new
battery of the same type. If a
wrong type of battery is used, it
may explode.
●Do not expose batteries to
extremely low pr essure due to
high altitude or extremely high
temperatures.
●Do not burn, bre ak or cut a bat-
tery.
NOTICE
■When replacing the battery
Use a flathead screwdriver of
appropriate size. Applying exces-
sive force may deform or damage
the cover.
■For normal operation after
replacing the battery
Observe the following precautions
to prevent accidents:
●Always work with dry hands.
Moisture may cause the battery
to rust.
●Do not touch or move any other
component inside the remote
control.
●Do not bend either of the battery
terminals.
