the power switch mode to the status it was in before the 12-volt battery was disconnected. Make sure to turn off
the power switch before disconnect the 12-volt battery. Take extra care when connecting the 12-volt battery if
the power switch mode prior to dis- charge is unknown.
If the hybrid system will not start even
after multiple attempts at all methods above, contact any authorized Toyota retailer or Toyota authorized repairer, or
any reliable repairer.
WARNING
■Chemicals in the 12-volt battery
The 12-volt battery contains poison-
ous and corrosive sulfuric acid and may produce hydrogen gas which is flammable and explosive. To reduce
the risk of death or serious injury, take the following precautions while work-ing on or near the 12-volt battery:
●Do not cause sparks by touching the 12-volt battery terminals with
tools.
●Do not smoke or light a match near
the 12-volt battery.
●Avoid contact with eyes, skin and
clothes.
●Never inhale or swallow electrolyte.
●Wear protective safety glasses when working near the 12-volt bat-
tery.
●Keep children away from the 12- volt battery.
■Where to safely charge the 12-volt battery
Always charge the 12-volt battery in
an open area. Do not charge the 12- volt battery in a garage or closed room where there is not sufficient
ventilation.
■Emergency measures regarding
electrolyte
●If electrolyte gets in your eyes
Flush your eyes with clean water for
at least 15 minutes and get immediate
medical attention. If possible, con-
tinue to apply water with a sponge or
cloth while traveling to the nearest
medical facility.
●If electrolyte gets on your skin
Wash the affected area thoroughly. If
you feel pain or burning, get medical
attention immediately.
●If electrolyte gets on your clothes
It can soak through clothing on to
your skin. Immediately take off the
clothing and follow the procedure
above if necessary.
●If you accidentally swallow electro- lyte
Drink a large quantity of water or milk.
Get emergency medical attention
immediately.
■When there is insufficient 12-volt
battery fluid
Do not use if there is insufficient fluid in the 12-volt battery. There is a pos-
sible danger that the 12-volt battery may explode.

Maintenance and care
Check if the treadwear indicators
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 “ ” marks, etc.,
molded into the sidewall of each tire.
Replace the tires if the treadwear indi-
cators are showing 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 inter- nal damage.
●A tire goes flat repeatedly or cannot be properly repaired due to the size or location of a cut or other damage.
If you are not sure, consult with any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
■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.
■If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.

WARNING
■When inspecting or replacing tires
Observe the following precautions to
prevent accidents. Failure to do so may cause damage to parts of the drive train as well as
dangerous handling characteristics, which may lead to an accident result-ing in death or serious injury.
●Do not mix tires of different makes, models or tread patterns.Also, do not mix tires of remarkably
different treadwear.

4887-3. Do-it-yourself maintenance
Rotate the tires in the order shown.
To equalize tire wear and help extend
tire life, Toyota recommends that tire
rotation is carried out approximately
every 5000 km (3000 miles).
Do not fail to initialize the tire pressure
warning system after tire rotation.
Front
■When rotating the tires
Make sure that the power switch is OFF. If the tires are rotated while the power
switch is in ON, the tire position informa- tion will not be updated.
If this accidentally occurs, either turn the
power switch to OFF and then to ON, or
initialize the system after checking that
the tire pressure is properly adjusted.
Your vehicle is equipped with a tire
pressure warning system that uses
tire pressure warning valves and
transmitters to detect low tire infla-
tion pressure before serious prob-
lems arise.
The tire pressure warning system
of this vehicle adopts a 2-type
warning system
 When “Adjust Pressure” is dis-
played (Normal Warning)
WARNING
●Do not use tire sizes other than those recommended by Toyota.
●Do not mix differently constructed 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 previously.
●Vehicles with compact spare tire: Do not tow if your vehicle has a
compact spare tire installed.
●Vehicles with emergency tire punc-
ture repair kit: Do not tow anything if a tire that has been repaired using the emergency tire puncture repair
kit is installed. The load on the tire may cause unexpected damage to the tire.
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 addi- tion, driving on rough roads may cause damage to the tires them-
selves, 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 display
the tire inflation pressure after the
power switch is turned to ON. It may
also take a few minutes to display the
tire inflation pressure after inflation
pressure has been adjusted.
●Tire inflation pressure changes with temperature. The displayed values
may also be different from the values
measured using a tire pressure
gauge.
■Situations in which the tire pres-
sure warning system may not oper-
ate properly
●In the following cases, the tire pres-
sure 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 specified
level.
• If wheels without 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 dis-
play, airport or other facility that gen-
erates strong radio waves or electrical
noise
• When carrying a portable radio, cellu-
lar phone, cordless phone or other
wireless communication device
If tire position information is not cor-
rectly displayed due to the radio wave
conditions, the display may be cor-
rected by driving and changing the
radio wave conditions.

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 the conditions under which it was initial-ized. 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.
When replacing tires or wheels, tire
pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure warn-
ing computer and the tire pressure
warning system must be initialized.
( P.495)
■When replacing the tires and
wheels
If the ID code of the tire pressure warn- ing valve and transmitter is not regis-
tered, the tire pressure warning system will not work properly. After driving for about 10 minutes, the tire pressure
warning light blinks for 1 minute and stays on to indicate a system malfunc-tion.
Installing tire pressure warn-
ing valves and transmitters
NOTICE
■Repairing or replacing tires, wheels, tire pressure warning
valves, transmitters and tire valve caps
