Maintenance and care
WARNING
QChemicals in the battery
Batteries contain poisonous 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 working on or near the
battery:
O Do not cause sparks by touching the battery terminals with tools.
O Do not smoke or light a match near the battery.
O Avoid contact with eyes, skin and clothes.
O Never inhale or swallow electrolyte.
O Wear protective safety glasses when working near the battery.
O Keep children away from the battery.
Q Where to safely charge the battery
Always charge the battery in an open area. Do not charge the battery in a
garage or closed room w here there is insufficient ventilation.
Q How to recharge the battery (vehicles with maintenance-free type bat-
tery)
Only perform a slow charge (5 A or less). The battery may explode if
charged at a quicker rate.
Q Emergency measures regarding electrolyte
O If electrolyte gets in your eyes
Flush 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.
O If electrolyte gets on your skin
Wash the affected area thoroughly. If you feel pain or burning, get medical
attention immediately.
O If electrolyte gets on your clothes
It can soak through clothing on to your skin. Immediately take off the cloth-
ing and follow the procedure above if necessary.
O If you accidentally swallow electrolyte
Drink a large quantity of water or milk. Get emergency medical attention
immediately.
O When there is insufficient battery fluid
Do not use if there is insufficient fluid in the battery. There is a possible
danger that the battery may explode.
Q When disconnecting the battery
Do not disconnect the negative (-) terminal on the body. The disconnected
negative (-) terminal may touch the positive (+) terminal, which may cause a
short and result in death or serious injury.

sion.
Washer fluid
WARNING
Q When adding washer fluid
Do not add washer fluid when the engine is hot or running as washer fluid
contains alcohol and may catch fi re if spilled on the engine etc.
NOTICE
QDo 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 problems of the washer fluid not spraying.
Q Diluting washer fluid
Dilute washer fluid with water as necessary.
Refer to the freezing temperatures list ed on the label of the washer fluid bot-
tle.

Maintenance and care
You may drain the fuel filter yourself. However, as the operation is dif-
ficult, we recommend having it drained by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer. Even if
you decide to drain it yourself, contact any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer.
The water in the fuel filter needs to be drained if one of the following
symptoms occurs:
Vehicles without multi-information display
When the fuel system warning light flashes and a buzzer sounds.
( P. 569)
Vehicles with multi-information display
When “Water accumulation in fuel filter See owner’s manual” is
shown on the multi-information display and a buzzer sounds*1.
Vehicles without smart entry & start system: Turn the engine switch
to the “LOCK” position.
Vehicles with smart entry & start system: Turn the engine switch off.
Place a small tray under the drain plug or drain hose to catch the
water and any fuel that comes out.
Perform the draining as shown in the illustration.
Turn the drain plug counter-
clockwise about 2 to 2 1/2
turns.
Loosening more than this will
cause water oozing from around
the drain plug.
Operate the priming pump
until fuel begins to run out.
After draining, tighten the drain plug by hand.

Maintenance and care
WARNING
QWhen 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 resulting
in death or serious injury.
O Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
O Do not use tire sizes other than those recommended by Toyota.
O Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
O Do not mix summer, all season and snow tires.
O 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
Q 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.
Q If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Maintenance and care
WARNING
QProper inflation is critical to save tire performance
Keep your tires properly inflated.
If the tires are not properly inflated, the following conditions may occur
which could lead to an accident resulting in death or serious injury:
O Excessive wear
O Uneven wear
O Poor handling
O Possibility of blowouts resulting from overheated tires
O Air leaking from between tire and wheel
O Wheel deformation and/or tire damage
O Greater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp edges in the road, etc.)
NOTICE
Q When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
If a valve cap is not installed, dirt or moisture may get into the valve and
cause an air leak, resulting in decreased tire inflation pressure.

Maintenance and care
WARNING
QWhen replacing wheels
O Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may result in a loss of handling control.
O Never use an inner tube in a leaking wheel which is designed for a tube-
less tire. Doing so may result in an accident, causing death or serious
injury.
Q When installing the wheel nuts
O Be sure to install the wheel nuts with the tapered ends facing inward.
( P. 592) Installing the nuts with the tapered ends facing outward can
cause the wheel to break and eventually cause the wheel to come off
while driving, which could lead to an accident resulting in death or seri-
ous injury.
O Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened,
leading to bolt or disc wheel damage. In addition, the oil or grease can
cause the wheel nuts to loosen and the wheel may fall off, causing an acci-
dent and resulting in death or serious injury. Remove any oil or grease
from the wheel bolts or wheel nuts.
Q Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing an
accident.
