Maintenance and care
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 your Scion dealer as the tire pressure
warning valves and transmitters may be damaged if not handled cor-
rectly.
●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 pressure warning valves and transmit-
ters
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 your Scion 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. 286)
■Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot-
holes.
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.
■If tire inflation pressure of e ach tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Tire inflation pressure
The recommended cold tire infla-
tion pressure and tire size are dis-
played on the tire and loading
information label. (P. 400)

Maintenance and care
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 usi ng 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 deflate.
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 pressure every two weeks, or at least once
a month.
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
●Reduced traction battery efficiency
●Reduced driving comfort and tire life
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating, have it checked by your Scion dealer.

■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.
The appearance of the tire can be misleading. In addition, tire inflation
pressure that is even just a few p ounds off can affect ride quality and
handling.
●Do not reduce tire inflation pressure after driving. It is normal for tire
inflation pressure to be higher after driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is
balanced.
CAUTION
■Proper inflation is critical to save tire performance
Keep your tires properly inflated . Otherwise, the following conditions
may occur and result in an accident causing death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts result ing from overheated tires
●Poor sealing of the tire bead
●Wheel deformation and/or tire separation
●A greater possibility of tire damage from road hazards
NOTICE
■When inspecting and adjusting tire inflation pressure
Be sure to put the tire valve caps back on.
Without the valve caps, dirt or moisture could get into the valve and
cause air leakage, which could result in an accident. If the caps are lost,
replace them as soon as possible.

Maintenance and care
Wheels
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim width and
inset
*.
Replacement wheels are available at your Scion dealer.
*: Conventionally referred to as “offset”.
Scion does not recommend using the following:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
● Use only Scion 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 after driving 1000 miles (1600 km).
● Be careful not to damage the aluminum wheels when using tire
chains.
● Use only Scion genuine balance weights or equivalent and a plastic
or rubber hammer when balancing your wheels.
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning
valves and transmitters that allow the tire pressure warning system to
provide advance warning in the event of a loss in tire inflation pressure.
Whenever wheels are replaced, tire pressure warning valves and trans-
mitters must be installed. ( P. 286)
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.

2967-3. Do-it-yourself maintenance
CAUTION
■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 for a
tubeless tire. Doing so may result in an accident, causing death or seri-
ous injury.
NOTICE
■Replacing tire pressure warning valves and transmitters
●Because tire repair or replacement may affect the tire pressure warn-
ing valves and transmitters, make sure to have tires serviced by your
Scion dealer or other qualified service shop. In addition, make sure to
purchase your tire pressure warning valves and transmitters at your
Scion dealer.
●Ensure that only genuine Scion wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly
with non-genuine wheels.

Maintenance and care
Air conditioning filter
Turn the power switch off.
Remove the filter cover.
Remove the air conditioning fil-
ter from between the knee air-
bag support and dash panel
insulator.
When removing the air condition-
ing filter, make sure that dust or dirt
does not enter the air conditioning
system.
The air conditioning filter must be cleaned or changed regularly
to maintain air conditioning efficiency.

If the filter is dirty, clean by blow-
ing compressed air through the fil-
ter as shown in the illustration.
Hold the air gun 2 in. (5 cm) from
the filter and blow for approxi-
mately 2 minutes at 72 psi (500
kPa, 5.0 kgf/cm
2 or bar).
If an air gun is not available, have
the filter cleaned by your Scion
dealer.
Replace the air conditioning filter
with a new one.
The “  UP” marks shown on the fil-
ter should be pointing up.
■ Checking interval
Inspect, clean and replace the air conditioning filter according to the mainte-
nance schedule. In dusty areas or areas with heavy traffic flow, more frequent
cleaning or early replacement may be required. (For scheduled maintenance
information, please refer to the “Scheduled Maintenance Guide” or \
“Owner’s
Manual Supplement”.)
■ If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and clean or replace if nece\
ssary.
