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.
nTire 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.
nEffects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
lReduced fuel economy
lReduced driving comfort and poor handling
lReduced tire life due to wear
lReduced safety
lDamage to the drivetrain
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:
lCheck 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.
lAlways use a tire pressure gauge.
It is difficult to judge if a tire is properly inflated based only on its appear-
ance.
lIt is normal for the tire inflation pressure to be higher after driving as
heat is generated in the tire. Do not
reduce tire inflation pressure after
driving.
lNever exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is
balanced.
WARNING
nProper 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:
lExcessive wear
lUneven wear
lPoor handling
lPossibility of blowouts result ing from overheated tires
lAir leaking from between tire and wheel
lWheel deformation and/or tire damage
lGreater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp edges in the road, etc.)
NOTICE
nWhen 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
Scion iM_U (12J49U)
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:
l Wheels of different sizes or types
l Used wheels
l Bent wheels that have been straightened
l Use only Scion wheel nuts and wrenches designed for use with
your aluminum wheels.
l When rotating, repairing or changi ng your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
l Use only Scion genuine balance weights or equivalent and a plastic
or rubber hammer when balancing your wheels.
nWhen 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. 221)
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.

ABS warning light Indicates a malfunction in:
• The ABS; or
• The brake assist system
 Have the vehicle inspected by your Scion dealer
immediately.
Electric power steering system warning light (warning
buzzer)
Indicates a malfunction in the EPS (Electric Power Steer-
ing) system
 Have the vehicle inspected by your Scion dealer
immediately.

When the tire pressure warning light comes on
Inspect the tires to check if a tire is punctured.
If a tire is punctured:
P. 272
If none of the tire s are punctured:
Turn the engine switch off then turn it to the “ON” position. Check if the
tire pressure warning light comes on or flashes.
If the tire pressure warning light comes on
After the temperature of the tires has lowered sufficiently, check the
inflation pressure of each tire and adjust them to the specified level.
If the warning light does not turn off even after several minutes have
elapsed, check that the inflation pressu re of each tire is at the specified
level and perform initialization. (P. 222)
If the warning light does not turn off even after several minutes have
elapsed, have the vehicle inspected by your Scion dealer immediately.
If the tire pressure warning light flashes for 1 minute then stays on
There may be a malfunction in the tire pressure warning system. Have
the vehicle inspected by your Scion dealer immediately.
nThe tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such
as natural air leaks and tire inflation pressure changes caused by temper-
ature. In this case, adjusting the ti re inflation pressure will turn off the
warning light (after a few minutes).
nWhen a tire is replaced with a spare tire
The compact spare tire is not equipped with a tire pressure warning valve
and transmitter. If a tire goes flat, the tire pressure warning light will not
turn off even though the flat tire has been replaced with the spare tire.
Replace the spare tire with the repaired tire and adjust the tire inflation
pressure. The tire pressu re warning light will go off after a few minutes.
nConditions that the tire pressure warning system may not function
properly
 P. 2 2 5
nWarning buzzer
In some cases, the buzzer may not be heard because of noisy place or an
audio sound.
n Electric power steering system warning light (warning buzzer)
When the battery charge becomes insufficient or the voltage temporarily
drops, the electric power steering system warning light may come on and the
warning buzzer may sound.

WARNING
nIf both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact your Scion
dealer. The vehicle will become extrem ely unstable during braking, and the
ABS system may fail, which could cause an accident resulting in death or
serious injury.
n When the electric power steerin g system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavie r than usual when operating, hold
firmly and operate using more force than usual.

If the tire pressure warning light comes on
Handling method ( P. 266)
Be sure to observe the following precautions. Failure to do so could
cause a loss of vehicle control and result in death or serious injury.
lStop your vehicle in a safe place as soon as possible. Adjust the tire
inflation pressure immediately.
lIf the tire pressure warning light comes on even after tire inflation pres-
sure adjustment, it is probable that you have a flat tire. Check the tires.
If a tire is flat, change it with th e spare tire and have the flat tire
repaired by the nearest Scion dealer.
lAvoid abrupt maneuvering and braking. If the vehicle tires deteriorate,
you could lose control of the steering wheel or the brakes.
nIf a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.
