If the light stays on, it indicates that the
SRS driver and front passenger airbag
system and/or front passenger occupant
classification system and “AIRBAG ON”
and “AIRBAG OFF” indicator lights have a
problem. If the light flashes, the SRS side
airbag system and/or curtain shield airbag
system have a problem.
The SRS warning light and “AIRBAG OFF”
indicator light will come on if there is a
malfunction in the front passenger occu-
pant classification system.
(l) “VSC” Warning Light
This light warns that there is a problem
somewhere in the vehicle stability control
system or traction control system.
The light will come on when the ignition
key is turned to “ON”, and will go off after
a few seconds.
If the light comes on while driving, the
system does not work. However, as con-
ventional braking operates when applied,
there is no problem to continue your driv-
ing.

OFF” indicator light will come on when the
“VSC” warning light comes on even if the
“TRAC OFF” switch is not pushed.
(m) Low Tire Pressure Warning Light
This light warns that the tire inflation pres-
sure is critically low. The light comes on
when the ignition key is turned to the
“ON” position. It goes off after a few sec-
onds. This indicates that the low tire pres-
sure warning system is functioning proper-
ly.
If the light comes on while driving, adjust
tire inflation pressure to the specified lev-
el. (See “Tires” on page 408 in Section 8.)
After the tire inflation pressure is adjusted,
push the tire pressure warning system re-
set 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.

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.

ly helps prevent the spinning of 4
wheels when the vehicle is started or
accelerated on slippery road surfaces.
When the ignition key is turned to “ON”,
the system automatically turns on.CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power against 4 wheels cannot be
maintained, even though the traction
control system is in operation. Do not
drive the vehicle under any speed or
maneuvering conditions which may
cause the vehicle to lose traction
control. In situations where the road
surface is covered with ice or snow,
your vehicle should be fitted with
snow tires or tire chains. Always
drive at an appropriate and cautious
speed for the present road condi-
tions.
NORMAL DRIVING MODE
Leave the system on during the ordi-
nary driving so that it can operate
when needed.
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
begins to move. This means that the trac-
tion control system is in the self
−check
mode, but does not indicate a malfunction.

Tw o −wheel drive models only—The “TRAC
OFF” indicator light will come on when the
“VSC” warning light comes on even if the
“TRAC OFF” switch is not pushed. The tire pressure warning system is de-
signed to provide warning when tire
inflation pressure is critically low while
the vehicle is moving. The low tire
pressure warning light comes on to in-
form you that such low tire pressure
may hamper driving.
This system is not designed to operate
when the vehicle is stopped. Therefore,
check the tire inflation pressure regularly.
The recommended cold tire inflation pres-
sure, tire size and the vehicle capacity
weight are on the tire and loading informa-
tion label. (For instructions, see “Checking
tire inflation pressure” on page 385 in
Section 7
−2.)
Installed tires should be of the specified
size. They should be of the same size
and construction. If tires other than the
specified size are used, or if tires of dif-
ferent sizes or constructions are mixed,
the tire pressure warning system will not
function properly.

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 408 in
Section 8.)
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
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 337 in Section 4.
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.
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.

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
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 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 underinflated 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 underinflated. 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 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.
