Vehicles without vehicle stability control
system—If the light comes on while driv-
ing, adjust tire inflation pressure to the
specified level. (See “Tires” on page 501
in Section 8.) After the tire inflation pres-
sure is adjusted, the light should go off
after driving at least 30 km/h (19 mph) for
some time. If the light still remains or
blinks once every second, have the low
tire pressure warning system checked at
your Toyota dealer.
Vehicles with vehicle stability control sys-
tem—If the light comes on while driving,
adjust tire inflation pressure to the speci-
fied level. (See “Tires” on page 501 in
Section 8.) 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 or blinks once
every second, have the low tire pressure
warning system checked at your Toyota
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 208 in Section 1 −7. (m) Low Windshield Washer Fluid Level
Warning Light
The light warns that the windshield washer
fluid level is too low. Add washer fluid at
your earliest opportunity. (For instructions,
see “Adding washer fluid” on page 487 in
Section 7 −3.)
(n) Engine Oil Replacement Reminder Light (for vehicles sold in U.S.A.)
This light acts as a reminder to replace
the engine oil.
This light will come on when the ignition
key is turned to “ON” and will go off after
about a few seconds.
When you drive for about 7200 km (4500
miles) after the engine oil replacement,
this light illuminates for about 3 seconds
and then flashes for about 12 seconds
with the ignition key turned to the “ON”
position. If you continue driving without
replacing the engine oil, and if the dis-
tance driven exceeds 8000 km (5000
miles), the light will come on after the
ignition key is turned to “ON” position.
The light will remain on thereafter. If the light is flashing, we recommend that
you replace the engine oil at an early
opportunity depending on the driving and
road conditions. If the light comes on,
replace it as soon as possible.
The system must be reset after the en-
gine oil replacement. Reset the system by
the following procedure:
1. Turn the ignition key to the “ACC” or “LOCK” position with the odometer
reading shown. (For details, see
“Odometer and two trip meters” on
page 186 in this Section.)
2. Turn the ignition key to the “ON” posi- tion while holding down the trip meter
reset button.
Hold down the button for at least 5 sec-
onds. The odometer indicates “000000”
and the light goes off.
If the system fails to reset, the light will
continue flashing.

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:
Vehicles with standard tires—1. Adjust the tire inflation pressure to the specified level as soon as pos-
sible. (See “Tires” on page 501 in
Section 8.) 2. Vehicles with vehicle stability control
system—Push the tire pressure warn-
ing system reset switch for a few
seconds and make sure the warning
light goes off.
Vehicles without vehicle stability control
system—Once the ignition switch is turned
off, the warning light also goes off. If the
light comes on again when the vehicle is
started after adjusting the tire inflation
pressure to the specified level, have the
tire pressure warning system checked at
your Toyota dealer.
Vehicles with vehicle stability control sys-
tem—If the light remains on after the re-
set switch has been pushed, have the tire
pressure warning system checked at your
Toyota dealer.
If you have a flat tire, replace it with the
spare tire. For details, see “If you have
a flat tire” on page 421 in Section 4.
Vehicles with runflat tires—
1. Decelerate at a speed below 90 km/h (55 mph), then adjust the tire pres-
sure to the specified level as soon
as possible. Do not drive more than
160 km (100 miles). 2. Vehicles with vehicle stability control
system—Push the tire pressure warn-
ing system reset switch for a few
seconds and make sure the warning
light goes off.
When the tire inflation pressure is be-
low 140 kPa (1.4 kgf/cm2 or bar, 20
psi), consult your Toyota dealer. If the
tire is flat or the tire inflation pressure
is below 100 kPa (1.0 kgf/cm
2 or bar,
15 psi), the tire must be replaced. Do
not use the repaired tire.
When the tire inflation pressure is 140
kPa (1.4 kgf/cm2 or bar, 20 psi) or
more, adjust it to specified level. (See
“Tires” on page 501 in Section 8.)
Vehicles without vehicle stability control
system—Once the ignition switch is turned
off, the warning light also goes off. If the
light comes on again when the vehicle is
started after adjusting the tire pressure to
the specified level, have the tire pressure
warning system checked at your Toyota
dealer.
Vehicles with vehicle stability control sys-
tem—If the light remains on after the re-
set switch has been pushed, have the tire
pressure warning system checked at your
Toyota dealer.

For details about the run−flat tires, see
“Run −flat tires” on page 476 in Section
7 −2.
If the warning light blinks once every
second:
The low tire pressure warning system may
be malfunctioning. Contact your Toyota
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.
The tread wear is uneven among the
tires.
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.
The pressure of two or more tires
drops at the same time.
Rapid acceleration/deceleration or
sharp turns is continue.
Towing a trailer.
The loading is over the limit or imbal-
anced.
Initialization was not performed correct-
ly after replacing or rotating tires or
wheels.
Vehicles with vehicle stability control
system—The outside temperature is be-
low 0 C (32F) or above 40 C (104 F).
CAUTION
When the tire pressure warning light
comes on, observe the following in-
structions:
Vehicles with the standard tires—
Adjust the tire inflation pressure to
the specified level as soon as pos-
sible.
Vehicles with the runflat tires—
Decelerate as soon as possible to
the lowest appropriate speed that
conditions permit. Do not drive for
longer than 160 km (100 miles) or
over 90 km/h (55 mph).
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 warning sys-
tem on your vehicle will warn you
when one of your tires is significantly
underinflated and when some com-
binations of your tires are significant-
ly underinflated. However, there are
other combinations of significantly
underinflated tires for which your
tire pressure warning system may not
warm you. These other combinations
are relatively common, accounting for
approximately half the instances in
which vehicles have significantly un-
derinflated tires. For example, your
system may not warm you when both
tires on the same side or on the
same axle of your vehicle are signifi-
cantly underinflated. It is particularly
important, therefore, for you to check
the tire pressure in all of your tires
regularly and maintain proper pres-
sure.
TIRE PRESSURE WARNING SYSTEM
RESET SWITCH
The tire pressure warning system need
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. 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 501 in Section 8.)
3. Turn the ignition key to “ON”. Vehicles with vehicle stability control
system only—If the low tire pressure
warning light comes on, push the reset
switch for a few seconds and make
sure the warning light goes off.
4. Push and hold the reset switch until the low tire pressure warning light
blinks three times.
Vehicles without vehicle stability control
system—Initialization is completed after
driving at the speeds of 30 km/h (19 mph)
or over for about 8 hours total, when the
tire pressure warning system detects the
normal tire pressure.

Vehicles with vehicle stability control sys-
tem—Initialization is completed after driv-
ing at the speeds of 30 km/h (19 mph) or
over for more than one hour. If the follow-
ing driving conditions are satisfied, initiali-
zation 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).
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 be failed
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 inflation 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 Toyota 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.
