If the indicator or buzzer comes on...Do this.
(h)Stop and check.
(i)Take vehicle to Scion dealer. If brake system warning light is also on, stop immediate-
ly and contact Scion dealer.
(j)Close all side doors and back door.
(k)Take vehicle to Scion dealer immediately.
(l)Adjust tire inflation pressure and turn off warning light by pushing reset switch for a
few seconds. If the warning light remains on, contact Scion dealer.
(m)Key reminder buzzerRemove key.
(n)Light reminder buzzerTurn off lights.

98
The light does not come on when the
ignition key is turned to the “ON” posi-
tion, or remains on.
The light comes on while you are driv-
ing.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Scion dealer.
In this case, not only the anti–lock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
(j) Open Door Warning Light
This light remains on until all the side
doors and back door are completely
closed. (k) SRS Warning Light
This light will come on when the igni-
tion key is turned to the “ON” position.
After about 6 seconds, the light will go
off. This means the systems of the air-
bags and seat belt pretensioners are
operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sensor
assemblies, curtain shield airbag sensor
assemblies, driver ’s seat position sensor,
driver’s seat belt buckle switch, front pas-
senger ’s seat belt buckle switch, seat belt
pretensioner assemblies, inflators, warning
light, interconnecting wiring and power
sources.
If any of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Scion dealer as
soon as possible to service the vehicle.
When the ignition key is turned to the
“ON” position, the light does not come
on, remains on for more than 6 sec-
onds.
The light comes on while driving.(l) Low Tire Pressure Warning Light
This light warns that the tire inflation pres-
sure of any one of the tires is critically
low. The light comes on when the ignition
key is turned to the “ON” position. It goes
off after a few seconds. This indicates
that the low tire pressure warning system
is functioning properly.
If the light comes on while driving, adjust
tire inflation pressure to the specified lev-
el. (See “Tires” on page 237.) After the
tire inflation pressure is adjusted, push the
tire pressure warning system reset switch
for a few seconds and make sure the
warning light goes off. If the light still
remains on or blinks once every second,
have the low tire pressure warning system
checked at your Scion dealer.
If the light blinks twice every second, the
low tire pressure warning system needs to
be initialized.
For details, see “Tire pressure warning
system” on page 107.
(m) Key Reminder Buzzer
This buzzer acts as a reminder to remove
the key when you open the driver’s door
with the ignition key in the “ACC” or
“LOCK” position.

LOW TIRE PRESSURE WARNING LIGHT
This light comes on when the ignition key
is turned to the “ON” position. It goes off
after a few seconds. This indicates that
the tire pressure warning system is func-
tioning properly.
If the low tire pressure warning light
comes on or blinks while driving, do
the following.If the warning light comes on:
1. Adjust the tire inflation pressure to the specified level as soon as pos-
sible. (See “Tires” on page 237.)
2. Push the tire pressure warning sys- tem reset switch for a few seconds
and make sure the warning light
goes off.
If the light remains on after the reset
switch has been pushed, have the tire
pressure warning system checked at your
Scion dealer.
If you have a flat tire, replace it with the
spare tire. For details, see “If you have
a flat tire” on page 172.
If the warning light blinks once every
second:
The low tire pressure warning system may
be malfunctioning. Contact your Scion
dealer.
If the warning light blinks twice every
second:
The low tire pressure warning system
needs to be initialized. Reset the system
with the tire pressure warning system re-
set switch. (To reset the system, see
“TIRE PRESSURE WARNING SYSTEM
RESET SWITCH”.) The tire pressure warning system does
not function properly under certain cir-
cumstances. In the following cases, the
low tire pressure warning light may not
come on even if the tire inflation pres-
sure is low, or it may come on when
the tire inflation pressure is actually
normal.
A compact spare tire, snow tires, or
tire chains are used.
The tire inflation pressure is excessive-
ly higher than specified, or tire inflation
pressure suddenly drops due to burst-
ing or other causes.
The vehicle is driven on a slippery
road surface such as rough or frozen
roads.
The vehicle speed is less than 30 km/h
(19 mph) or more than 100 km/h (62
mph), and the driving duration is less
than 5 minutes.
The tires differ in tread pattern or
manufacturer.
The tires are not the specified size.
The tread wear is very different among
the installed tires.
Rapid acceleration/deceleration or
sharp turns is continued.

109

The loading is over the limit or imbal-
anced.
Initialization was not performed correct-
ly after replacing or rotating tires or
wheels.
The outside temperature is below 0
C
(32 F) or above 40 C (104 F).
CAUTION
When the tire pressure warning light
comes on, observe the following in-
structions:
Adjust the tire inflation pressure to
the specified level as soon as pos-
sible.
Avoid abrupt steering wheel maneu-
vering and braking. If the vehicle
tires deteriorate, you could lose
control of the steering wheel or the
brakes, causing death or serious in-
jury.
Note: The tire pressure monitoring
system on your vehicle will warn you
when one of your tires is significantly
under–inflated and when some com-
binations of your tires are significant-
ly under–inflated. However, there are
other combinations of significantly
under–inflated tires for which your
tire pressure monitoring system may
not warn you. These other combina-
tions are relatively common, account-
ing for approximately half the
instances in which vehicles have sig-
nificantly under–inflated tires. For ex-
ample, your system may not warn you
when both tires on the same side or
on the same axle of your vehicle are
significantly under–inflated. It is par-
ticularly important, therefore, for you
to check the tire pressure in all of
your tires regularly and maintain
proper pressure.

TIRE PRESSURE WARNING SYSTEM
RESET SWITCH
The tire pressure warning system needs
to be initialized in the following condi-
tions:
When the low tire pressure warning
light blinks twice every second
After replacing or rotating tires or
wheels
When initializing the system, the pres-
ent tire condition is stored as a stan-
dard.

11 0
To initialize the system, perform the fol-
lowing:1. Park the vehicle at a safe place and apply the parking brake. Stop the en-
gine.
2. Adjust the pressure of all the installed tires to the specified level. (See “Tires”
on page 237.)
3. Turn the ignition key to “ON”.
If the low tire pressure warning light
comes on, push the reset switch for a
few seconds and make sure the warn-
ing light goes off.
4. Push and hold the reset switch until the low tire pressure warning light
blinks three times.
Initialization is completed after driving at
the speeds of 30 km/h (19 mph) or over
for more than one hour. If the following
driving conditions are satisfied, initializa-
tion will be completed in about one hour.
The vehicle speed is between 50 km/h
(31 mph) and 100 km/h (62 mph).
The roads are dry, smooth and straight.
The number of passengers is 1 or 2
(including driver).
17T004
When initializing the system, make sure
the low tire pressure warning light blinks
three times. If the warning light does not
blink three times, initializing will not occur
and the tire pressure warning system will
not function properly.
Do not push the reset switch without ad-
justing the tire inflation pressure to the
specified level. Otherwise, the low tire
pressure warning light may not come on
even if the tire pressure is low, or it may
come on when the tire inflation pressure
is actually normal.
If you push the reset switch while the
vehicle is moving, initialization is not per-
formed. If the low tire pressure warning light does
not blink when you push and hold the
reset switch, have the low pressure warn-
ing system checked at your Scion dealer.
When the warning light blinks twice every
second while driving, you may be unable
to reset the system. In this case, set the
system again according to the above pro-
cedure.
