add washer fluid.
WARNING
●Avoid contact with eyes, skin and clothes.
●Never inhale or swallow electrolyte.
●Wear protective safety glasses when working near the battery.
●Keep children away from the bat-tery.
■Where to safely charge the bat-tery
Always charge the battery in an open
area. Do not charge the battery in a garage or closed room where there is insufficient ventilation.
■Emergency measures regarding electrolyte
●If electrolyte gets in your eyesFlush your eyes with clean water for at least 15 minutes and get immedi-
ate medical attention. If possible, continue 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 med-ical attention immediately.
●If electrolyte gets on your clothesIt 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 atten-tion immediately.
■When disconnecting the battery
Do not disconnect the negative (-) ter-
minal on the body side. The discon- nected negative (-) terminal may touch the positive (+) terminal, which
may cause a short and result in death or serious injury.
NOTICE
■When recharging the battery
Never recharge the battery while the
engine is running. Also, be sure all accessories are turned off.
Adding the washer fluid
WARNING
■When adding washer fluid
Do not add washer fluid when the engine is hot or running as washer fluid contains alcohol and may catch
fire if spilled on the engine, etc.
NOTICE
■Do not use any fluid other than washer fluid
Do not use soapy water or engine
antifreeze instead of washer fluid. Doing so may cause streaking on the vehicle’s painted surfaces, as well as
damaging the pump leading to prob- lems of the washer fluid not spraying.
■Diluting washer fluid
Dilute washer fluid with water as nec- essary.
Refer to the freezing temperatures listed on the label of the washer fluid bottle.

6-3. Do-it-yourself maintenance
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 “ ” mark, 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.
■Low profile tires (16 and 17-inch
tires)
Generally, low profile tires will wear
more rapidly and tire grip performance
will be reduced on snowy and/or icy
roads when compared to standard tires.
Be sure to use snow tires on snowy
and/or icy roads and drive carefully at a
speed appropriate for road and weather
conditions.
■If the tread on snow tires wears
down below 4 mm (0.16 in.)
The effectiveness of the tires as snow
tires is lost.
■Checking the tire valves
When replacing the tires, check the tire
valves for deformation, cracks, and
other damage.
Tires
Replace or rotate tires in
accordance with maintenance
schedules and treadwear.

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.
●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.
NOTICE
■Low profile tires (16 and 17-inch
tires)
Low profile tires may cause greater damage than usual to the tire wheel
when sustaining impact from the road surface. Therefore, pay attention to the following:
●Be sure to use proper tire inflation pressure. If tires are under-inflated,
they may be damaged more severely.
●Avoid potholes, uneven pavement, curbs and other road hazards. Fail-ure to do so may lead to severe tire
and wheel damage.
■If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires
and/or wheels may be ruined.
■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.
Tire rotation

332
YARIS(HB) Owner's Manual_Europe_MK0001_en
6-3. Do-it-yourself maintenance
Front
To equalize tire wear and help extend
tire life, Toyota recommends that tire
rotation is carried out approximately
every 10000 km (6000 miles).
When rotating front and rear tires which
have different tire inflation pressures,
do not fail to initialize the tire pressure
warning system after tire rotation.
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.
zWhen “Adjust Pressure” is dis-
played (Normal Warning)
A warning with the tire pressure warn-
ing light and warning buzzer when
there is an unknown level of low tire
pressure with the appearance of the tire
due to natural air leakage as well as the
pressure lowering due to changes in
the pressure according to the outside
temperature. (Ways of coping: →P.375,
417)
zWhen “Immediately Check tire
when Safe” is displayed (Emer-
gency Warning)
A warning with the tire pressure warn-
ing light and warning buzzer when
there is a known level of low tire pres-sure with the appearance of the tire due
to pressure suddenly lowering. (Ways
of coping: →P.379, 389)
However, the system may not be able
to detect sudden tire ruptures (bursting,
etc.).
The tire pressure detected by the
tire pressure warning system can
be displayed on the multi-informa-
tion display.
The unit can be changed.
■How to change the unit
1Park the vehicle in a safe place
and turn the engine switch off.
Changing the unit cannot be performed
while the vehicle is moving.
2Turn the engine switch to ON.

■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
engine 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 tires not equipped with 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.
●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
driving conditions. 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.
Installing tire pressure warn-
ing valves and transmitters

334
YARIS(HB) Owner's Manual_Europe_MK0001_en
6-3. Do-it-yourself maintenance
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure warn-
ing computer and the tire pressure
warning system must be initialized.
Have tire pressure warning valves
and transmitter ID codes regis-
tered any authorized Toyota retailer
or Toyota authorized repairer, or
any reliable repairer. ( →P.336)
■Replacing 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.■The tire pressure warning sys-
tem must be initialized in the
following circumstances:
z When rotating front and rear tires
which have different tire inflation
pressures.
z When changing the tire size.
z When the tire inflation pressure
is changed such as when chang-
ing traveling speed or load
weight.
z When changing between two
registered wheel sets.
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 warning valves, transmitters and tire valve caps
●When removing or fitting the wheels, tires or the tire pressure warning valves and transmitters,
contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer as
the tire pressure warning valves and transmitters may be damaged if not handled correctly.
●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 tire valve caps, do not use tire valve caps other than those specified. The cap may
become stuck.
■To avoid damage to the tire pres-
sure warning valves and trans- mitters
When a tire is repaired with liquid
sealants, the tire pressure warning valve and transmitter may not operate properly. If a liquid sealant is used,
contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer as soon as possible.
Make sure to replace the tire pressure warning valve and transmitter when replacing the tire. ( →P.333)

then press and hold .
6Press / to select “TPWS
setting” and then press .
7Press / to select “Setting
Pressure”. Then press and hold
until the tire pressure warn-
ing light blinks 3 times.
Then a message will be displayed on
the multi-information display. “--” will be
displayed on the multi-information dis-
play for the inflation pressure of each tire while initialization is being per-
formed.
8Drive straight (with occasional
left and right turns) at approxi-
mately 40 km/h (25 mph) or
more for approximately 10 to 30
minutes.
Initialization is complete when the posi-
tion of each tire is determined and the
inflation pressure of each tire is dis-
played on the multi-information display.
Initialization may take longer than
approximately 1 hour in certain situa-
tions, such as when the vehicle is
stopped for a long time at traffic lights,
etc. (→P.337)
■Initialization procedure
●Make sure to carry out initialization
after adjusting the tire inflation pres-
sure.
Also, make sure the tires are cold
before carrying out initialization or tire
inflation pressure adjustment.
●If you have accidentally turned the
engine switch off during initialization, it
is not necessary to press the reset
switch again as initialization will
restart automatically when the engine
switch is turned to ON the next time.
●If you accidentally press the reset
switch when initialization is not neces-
sary, adjust the tire inflation pressure
to the specified level when the tires
are cold, and conduct initialization
again.
●While the position of each tire is being

336

6-3. Do-it-yourself maintenance
determined and the inflation pres-
sures are not being displayed on the multi-information display, if the infla-tion pressure of a tire drops, the tire
pressure warning light will come on.
■If the tire pressure warning system is not initialized properly
●In the following situations, initialization may take longer than usual to be com-pleted or may not be possible. (Usu-
ally, the vehicle will need to be driven for approximately 10 to 30 minutes to complete initialization.) If initialization
is not complete after driving approxi- mately 30 minutes, continue driving for a while.
• If the vehicle is driven on an unpaved road, it may take longer to complete initialization.
• If the vehicle is backed up while per- forming initialization, data collected during initialization will be cleared and
it will take longer than normal to com- plete.• If the vehicle is driven in heavy traffic
or another situation where other vehi- cles are driven close by, it may take time for the system to recognize the
tire pressure warning valve and trans- mitters of your vehicle over those of other vehicles.
If initialization is not complete after driv-
ing for approximately 1 hour, park the
vehicle in a safe place for approximately
20 minutes and then drive the vehicle
again.
●In the following situations, initialization will not be started or was not com-
pleted properly and the system will not operate properly. Perform the initial-ization procedure again.
• If, when attempting to start initializa- tion, the tire pressure warning light does not blink 3 times.
• If, when the vehicle has been driven for about 20 minutes after performing initialization, the tire pressure warning
light blinks for approximately 1 minute and then illuminates.
●If initialization cannot be completed
after performing the above procedure,
contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
The tire pressure warning valve
and transmitter is equipped with a
unique ID code. When replacing a
tire pressure warning valve and
transmitter, it is necessary to regis-
ter the ID code.
The ID codes can be registered on
of the multi-information display.

WARNING
■When initializing the tire pres- sure warning system
Do not initialize the tire pressure
warning system without first adjusting the tire inflation pressure to the speci-fied level. Otherwise, the tire pressure
warning light may not come on even if the tire inflation pressure is low, or it may come on when the tire inflation
pressure is actually normal.
