2022 TOYOTA AVALON HYBRID maintenance

4486-3. Do-it-yourself maintenance
NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valve
and transmitters and tire valve caps
●When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitters, contact your Toyota dealer as the tire pressure
warning valve and transmitters may be damaged if not handled co r-
rectly.
●Make sure to install the tire val ve caps. If the tire valve caps are not
installed, water may enter the valves of the tire pressure warn ing valve
and transmitters and the valves may become stuck.
●When replacing tire valve caps, do not use tire valve caps othe r than
those specified. The cap may become stuck.
■To avoid damage to the tire pressure warning valve and transmit -
ters
When a tire is repaired with liqui d sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sea lant is
used, contact your Toyota dealer or other qualified service shop as soon
as possible. Make sure to replace the tire pressure warning valve and
transmitter when replacing the tire. ( P. 439)
■Driving on rough roads
Take particular care when drivi ng on roads with loose surfaces or pot-
holes.
These conditions may cause losses in tire inflation pressure, reducing
the cushioning ability of the t ires. In addition, driving on ro ugh roads
may cause damage to the tires themselves, as well as the vehicl e’s
wheels and body.
■Low profile tires (vehicles w ith 18 or 19-inch wheels)
Low profile tires may cause gre ater 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 und er-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 drivi ng
Do not continue driving, or your t ires and/or wheels may be ruined.

Maintenance and care
The recommended cold tire infla-
tion pressure and tire size are dis-
played on the tire and loading
information label. (P. 530)

Tire valve
Tire pressure gauge
Remove the tire valve cap.
Press the tip of the tire pressure gauge onto the tire valve.
Read the pressure using the gauge gradations.
If the tire inflation pressure is not at the recommended level, adjust
the pressure.
If you add too much air, press the center of the valve to defla te.
After completing the tire inflation pressure measurement and
adjustment, apply soapy water to the valve and check for leakage.
Put the tire valve cap back on.
■Tire inflation pressure check interval
You should check tire inflation p ressure every two weeks, or at least once
a month.
Do not forget to check the spare.
■Effects of incorrect tire inflation pressure
Driving with incorrec t tire inflation pressure may result in th e following:
●Reduced fuel economy
●Reduced driving comfort and poor handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drivetrain
If a tire needs frequent inflating , have it checked by your Toyota dealer.

Maintenance and care
■Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours or has not been
driven for more than 1 mile or 1.5 km, you will get an accurate cold tire
inflation pressure reading.
●Always use a tire pressure gauge.
It is difficult to judge if a tire is properly inflated based o nly on its appear-
ance.
●It is normal for the tire inflation pressure to be higher after driving as
heat is generated in the tire. Do not reduce tire inflation pre ssure after
driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehi cle is
balanced.
WARNING
■Proper inflation is critical to save tire performance
Keep your tires properly inflated.
If the tires are not properly in flated, the following conditions may occur
which could lead to an accident resulting in death or serious i njury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting from overheated tires
●Air leaking from between tire and wheel
●Wheel deformation and/or tire damage
●Greater possibility of tire damage while driving (due to road h azards,
expansion joints, sharp edges in the road, etc.)
NOTICE
■When inspecting and adjusti ng 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 pressu re.

4526-3. Do-it-yourself maintenance
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim wid th and
inset
*.
Replacement wheels are available at your Toyota dealer.
*: Conventionally referred to as “offset”.
Toyota does not recommend using the following:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that hav e been straightened
● Use only Toyota wheel nuts and wrenches designed for use with
your aluminum wheels.
● When rotating, repairing or changi ng your tires, check that the
wheel nuts are still tight afte r driving 1000 miles (1600 km).
● Be careful not to damage the aluminum wheels when using tire
chains.
● Use only Toyota genuine balance we ights or equivalent and a plas-
tic or rubber hammer when balancing your wheels.
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warn ing valve
and transmitters that allow the tire pressure warning system to provide
advance warning in the event of a loss in tire inflation pressu re. When-
ever wheels are replaced, tire pressure warning valve and trans mitters
must be installed. ( P. 439)
Wheels
If a wheel is bent, cracked or heavily corroded, it should be
replaced. Otherwise, the tire may separate from the wheel or
cause a loss of handling control.

Maintenance and care
WARNING
■When replacing wheels
●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.
●Never use an inner tube in a leaking wheel which is designed fo r a
tubeless tire. Doing so may result in an accident, causing death or seri-
ous injury.
■When installing the wheel nuts
●Be sure to install the wheel nuts with the tapered ends facing
inwar
d.( P. 501) Installing the nuts with the tapered ends facing out-
ward can cause the wheel to break and eventually cause the whee l to
come off while driving, which could lead to an accident resulti ng in
death or serious injury.
●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 g rease can
cause the wheel nuts to loosen and the wheel may fall off, causing an
accident and resulting in death or serious injury. Remove any o il or
grease from the wheel bolts or wheel nuts.
NOTICE
■Replacing tire pressure warning valve and transmitters
●Because tire repair or replacement may affect the tire pressure warn-
ing valve and transmitters, make sure to have tires serviced by your
Toyota dealer or other qualified service sh op. In addition, make sure to
purchase your tire pressure warning valve and transmitters at y our
Toyota dealer.
●Ensure that only genuine Toyota wheels are used on your vehicle .
Tire pressure warning valve and transmitters may not work prope rly
with non-genuine wheels.

Maintenance and care
Remove the air conditioning fil-
ter from the filter case and
replace it with a new one.
The “UP” marks shown on the fil-
ter and the filter case should be
pointing up.
■ Checking interval
Inspect and replace the air conditioning filter according to the maintenance
schedule. In dusty areas or areas with heavy traffic flow, early replacement
may be required. (For scheduled maintenance information, please refer to the
“Schedule maintenance guide” or “Owner’s Manual Supplement”.)
■ If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if nece ssary.
■ Air conditioning filter with deodorizing function
When fragrances are placed in your vehicle, the deodorizing effect may
become significantly weakened in a short period.
When an air conditioning odor comes out continuously, replace the air condi-
tioning filter.

NOTICE
■When using the air conditioning system
Make sure that a filter is always installed.
Using the air conditioning system without a filter may cause da mage to the
system.
■ To prevent damage to the filter cover
When moving the filter cover in the direc-
tion of arrow to release the fitting, pay
attention not to apply excessive force to
the claws. Otherwise, the claws may be
damaged.
