Maintenance and care
Scion iM_U (12J49U)
Your vehicle is equipped with a tire pressure warning system that uses
tire pressure warning valves and tr ansmitters to detect low tire infla-
tion pressure before serious problems arise.
If the tire pressure drops below a predetermined level, the driver is
warned by a warning light. ( P. 263)
uInstalling tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new ID codes must be registered in the tire pressure
warning computer and the tire pr essure warning system must be
initialized. Have tire pressure warning valves and transmitter ID
codes registered by your Scion dealer. ( P. 223)
uInitializing the tire pressure warning system
nThe tire pressure warning system must be initialized in the fol-
lowing circumstances:
l When rotating front and rear tires which have different tire infla-
tion pressures.
l When changing the tire size.
l When the tire inflation pressure is changed such as when chang-
ing traveling speed or load weight.
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.

How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the engine switch off.
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. ( P. 301)
Make sure to adjust the tire pressu re to the specified cold tire infla-
tion pressure level. The tire pressure warning system will operate
based on this pressure level.
Turn the engine switch to the “ON” position.
Open the glove box. Press
and hold the tire pressure
warning reset switch until the
tire pressure warning light
blinks slowly 3 times.
Wait for a few minutes with the eng ine switch in the “ON” position
and then turn the engine switch to the “ACC” or “LOCK” position.

uRegistering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to register the ID code. Have the ID code
registered by your Scion dealer.
nWhen to replace your vehicle’s tires
Tires should be replaced if:
lThe treadwear indicators are showing on a tire.
lYou have tire damage such as cuts, splits, cracks deep enough to
expose the fabric, and bulges indicating internal damage
lA tire goes flat repeatedly or cannot be properly repaired due to the size
or location of a cut or other damage
If you are not sure, consult with your Scion dealer.
nReplacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not reg-
istered, the tire pressure warning system will not work properly. After driv-
ing for about 20 minutes, the tire pressure warning light blinks for 1
minute and stays on to indicate a system malfunction.
nTire life
Any tire over 6 years old must be checked by a qualified technician even
if it has seldom or never been used or damage is not obvious.
nRoutine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation
pressure checks. Make sure to check tire inflation pressure as part of
your routine of daily vehicle checks.
nLow profile tires
Generally, low profile tires will wear mo re rapidly and tire grip perfor-
mance will be reduced on snowy and /or icy roads when compared to
standard tires. Be sure to use snow tires on snowy and/or icy roads and
drive carefully at a speed appropriate for road and weather conditions.

Situations in which the tire pressure warning system may not oper-
ate properly
lIn the following cases, the tire pr
essure warning system may not operate
properly.
• If non-genuine Scion wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equip- ment) tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains etc. are equipped.
• An auxiliary-supported run- flat tire is equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the
wheels or wheel housings.
• If the tire inflation pressure is extremely higher than the specified level.
• If tires not equipped with tire pressure warning valves and transmit-
ters are used.
• If the ID code on the tire pressure warning valves and transmitters is not registered in the tire pressure warning computer.
lPerformance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, largedisplay, airport or other facility that generates strong radio waves or
electrical noise.
• When carrying a portable radio, cellular phone, cordless phone or other wireless communication device.
lWhen the vehicle is parked, the time taken for the warning to start or go
off could be extended.
lWhen tire inflation pressure declines rapidly for example when a tire has
burst, the warning may not function.

The initialization operation
lMake sure to carry out in
itialization after adjusting the tire inflation pres-
sure.
Also, make sure the tires are cold be fore carrying out initialization or tire
inflation pressure adjustment.
lIf you have accidentally turned the engine switch off during initialization,
it is not necessary to press the reset switch again as initialization will
restart automatically when the engine switch to the “ON” position for the
next time.
lIf you accidentally press the reset s witch when initialization is not neces-
sary, adjust the tire inflation pressu re to the specified level when the
tires are cold, and conduct initialization again.
nWarning performance of the ti re pressure warning system
The warning of the tire pressure warning system will change in accor-
dance with driving conditions. For th is reason, the system may give a
warning even if the tire pressure does not reach a low enough level, or if
the pressure is higher than the pressure that was adjusted to when the
system was initialized.
nWhen initialization of the tire pr essure warning system has failed
Initialization can be completed in a few minutes. However, in the following
cases, the settings have not been recorded and the system will not oper-
ate properly. If repeated attempts to record tire inflation pressure settings
are unsuccessful, have the vehicl e inspected by your Scion dealer.
lWhen operating the tire pressure wa rning reset switch, the tire pressure
warning light does not blink 3 times.
lAfter driving for a certain period of time since the initialization has been
completed, the warning light comes on after blinking for 1 minute.
