Tire inflation pressure

The recommended cold tire inflation pressure and tire size are
displayed on the tire and loading information label. (

■

Tire inflation pressure check interval

You should check tire inflation pressure every two weeks, or at least
once a month.
Do not forget to check the spare.

■

Inspection and adjustment procedure

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
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.

■

Effects of incorrect tire inflation pressure

Driving with incorrect tire inflation pressure may result in the following:

●

Reduced fuel 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 infla-
tion pressure that is even just a few pounds off can affect ride quality
and handling.

●

Do not reduce tire inflation pressure after driving. It is normal for the
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 resulting 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.

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.

■

Wheel selection

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

266

4-3. Do-it-yourself maintenance

Scion_xD_OM_OM52E36U_(U)

■

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. 253)

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.

■

When installing the wheel nuts

●

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
accident and resulting in death or serious injury. Remove any oil or
grease from the wheel bolts or wheel nuts.

●

Be sure to install the wheel nuts with
the tapered end facing inward. Install-
ing the nuts with the tapered end fac-
ing outward can cause wheel to
break and eventually cause a wheel
to come off while driving, which could
lead to an accident resulting in death
or serious injury.

■

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.

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 “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 replace if necessary.

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 damage to the
system.
