“TOYOTA Genuine 50/50 Pre-mixed
Super Long Life Coolant BLUE” is a mix- ture of 50% coolant and 50% deionized
water. (Minimum temperature: -35°C
[-31°F])
For more details about engine coolant,
contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
■If the coolant level drops within a
short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir caps, drain
cock and water pump.
If you cannot find a leak, have your Toyota dealer test the cap and check for
leaks in the cooling system.
Check the radiator and condenser
and clear away any foreign objects.
If either of the above parts is
extremely dirty or you are not sure
of their condition, have your vehicle
inspected by any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.
Check the battery as follows.
■Battery exterior
Make sure that the battery termi-
nals are not corroded and that there
are no loose connections, cracks,
or loose clamps.

■Checking battery fluid
Check that the level is between the
“UPPER LEVEL” and “LOWER
LEVEL” lines.
WA R N I N G
■When the engine is hot
Do not remove the engine coolant reservoir cap. ( P.364)
The cooling system may be under
pressure and may spray hot coolant if the cap is removed, causing serious
injuries, such as burns.
NOTICE
■When adding coolant
Coolant is neither plain water nor
straight antifreeze. The correct mix-
ture of water and antifreeze must be used to provide proper lubrication,
corrosion protection and cooling. Be
sure to read the antifreeze or coolant label.
■If you spill coolant
Be sure to wash it off with water to
prevent it from damaging parts or
paint.

If the fluid level is at or below the
“LOWER LEVEL” line, add distilled
water.
■Adding distilled water
1 Remove the vent plug.
2 Add distilled water.
If the “UPPER LEVEL” line cannot be seen, check the fluid level by looking
directly at the cell.
3 Put the vent plug back on and
close it securely.
■Before recharging
When recharging, the battery produces
hydrogen gas which is flammable and
explosive. Therefore, observe the fol- lowing before recharging:
●If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
●Make sure the power switch on the
charger is off when connecting and disconnecting the charger cables to
the battery.
■After recharging/reconnecting the
battery
The engine may not start. Follow the
procedure below to initialize the system.
1 Shift the shift lever to P (automatic
transmission) or depress the brake pedal with the shift lever in N (man-
ual transmission).
2 Open and close either door.
3 Restart the engine.
●Unlocking the doors using the smart
entry & start system may not be possi-
ble immediately after reconnecting the battery. If this happens, use the wire-
less remote control or the mechanical
key to lock/unlock the doors.
●Start the engine with the engine
switch in ACC. The engine may not start with the engine switch turned off.
However, the engine will operate nor-
mally from the second attempt.
●The engine switch mode is recorded
by the vehicle. If the battery is discon- nected and reconnected, the vehicle
will return the engine switch mode to
the status it was in before the battery was disconnected. Make sure to turn
off the engine before disconnecting
the battery. Take extra care when con- necting the battery if the engine switch
mode prior to the battery being dis-
connected is unknown.
If the engine will not start even after mul-
tiple attempts, contact any authorized Toyota dealer or repairer, or another
duly qualified and equipped profes-
sional.

■Chemicals in the battery
Batteries contain poisonous and cor-
rosive 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 working on or near
the battery:
●Do not cause sparks by touching the battery terminals with tools.
●Do not smoke or light a match near the battery.
●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 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.

Maintenance and care
Current fluid level
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.
WA R N I N G
■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.

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 dealer or repairer, or another duly qualified and equipped pro-
fessional.
■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
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 or tire chains
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.
WA R N I N G
■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.
●Make sure to insta ll 4 tires that are
of the specified size, and that all 4
tires are the same size, same maker, same brand and tread pat-
tern.
●Do not use tire sizes other than
those recommended by Toyota.
●Only use radial 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
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.

6-3. Do-it-yourself maintenance
Maintenance and care
Rotate the tires in the order shown.
Front
To equalize tire wear and extend tire
life, Toyota recommends that tire rota-
tion is carried out at the same interval
as tire inspection.
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 detected by the
tire pressure warning system can
be displayed on the multi-infor-
mation display.
 If the tire pressure drops below a
predetermined level, the driver is
warned by a screen display and
a warning light. ( P.342)
■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
NOTICE
■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.

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. • When driving near a TV tower, electric
power plant, gas station, radio station,
large display, airport or other facility
that generates 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 correctly
displayed due to the radio wave condi- tions, the display ma y be corrected by
driving and changing the radio wave
conditions.
●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.
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 pressu re warning valve
and transmitter ID codes regis-
tered by any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.
( P. 3 0 6 )
■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
