Tires and loading on yourTo y o t a
Underinflated or overinflated tire pressure and the
excess load may result in the deterioration of
steering ability and braking ability, leading to an
accident. Check the tire inflation pressure periodi-
cally and be sure to keep the load limits given in
this Owner ’s Manual. For details about tire inflation
pressure and load limits, see pages 388 and 463.
Scrapping of your Toyota
The SRS airbag and seat belt pretensioner devices in your
Toyota contain explosive chemicals. If the vehicle is
scrapped with the airbags and pretensioners left as they
are, this may cause an accident such as fire. Be sure to
have the systems of the SRS airbag and seat belt preten-
sioner removed and disposed of by the qualified service
shop or by your Toyota dealer before you dispose of your
vehicle.

(k) “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.
In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the ignition key is turned to “ON”.
The warning light remains on after the
ignition key is turned to “ON”.
The warning light comes on while driv-
ing.
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. (l) Low Tire Pressure Warning Light
This light warns that the tire pressure 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 491 in Section 8.)
After the tire inflation pressure 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 warn-
ing 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 188 in Section 1
−6.
(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 479 in
Section 7 −3.) (n) Engine Oil Replacement Reminder
Light (for vehicles sold in U.S.A.)
This light reminds you when 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 8000 km (5000
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 12000 km (7500
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.

In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the ignition key is turned to “ON”.
The warning light remains on after the
ignition key is turned to “ON”.
The warning light comes on while driv-
ing.
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
pressure of any one of the tires is criti-
cally low while the vehicle is moving.
The low tire pressure warning light
comes on to inform 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 pressure regularly. The rec-
ommended cold tire pressure, tire size
and the vehicle capacity weight are on the
tire pressure label. (For instructions, see
“Checking tire inflation pressure” on page
463 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:
Vehicles with standard tires—
Adjust the tire pressure to the specified
level as soon as possible. (See “Tires”
on page 491 in Section 8.)

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.
If you have a flat tire, replace it with the
spare tire. For details, see “If you have
a flat tire” on page 411 in Section 4.
Vehicles with runflat tires—
Decelerate at a speed below 90 km/h
(55 mph), then adjust the tire pressure
to the specified level as soon as pos-
sible. Do not drive more than 160 km
(100 miles).
When the tire pressure is below 140
kPa (1.4 kgf/cm2 or bar, 20 psi), con-
sult your Toyota dealer. If the tire is
flat or the tire 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 pressure is 140 kPa (1.4
kgf/cm2 or bar, 20 psi) or more, adjust
it to specified level. (See “Tires” on
page 491 in Section 8.) 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 pres-
sure to the specified level, have the
tire pressure warning system checked
at your Toyota dealer.
For details about the run −flat tires, see
“Run −flat tires” on page 469 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 pressure is
low, or it may come on when the tire
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 pressure is excessively higher
than specified, or tire pressure sudden-
ly drops due to bursting 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.
CAUTION
When the tire pressure warning light
comes on, observe the following in-
structions:
Vehicles with the standard tires—
Adjust the tire pressure to the spe-
cified level as soon as possible.
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

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.

The system may not detect the follow-
ing.
Thin objects such as a wire or rope
Objects with a surface area too small
to reflect ultrasonic waves such as
wire gauze
Sound wave absorbing objects or mate-
rial such as cotton or snow
A person near the vehicle (depending
on the type of clothes worn)
Objects with a sharp edge
Small or short objects
Tall objects with an upper part project-
ing toward the vehicle
Objects just under the bumper
Objects very close to your vehicle
In the following cases, have your
Toyota dealer check the system.
When the bumper is damaged.
When the indicator is continuously on. The rear view monitor system assists
the driver by displaying an image of
the rear of the vehicle while backing
up. The displayed image on the screen
is a horizontally reversed mirror image
of the inside rear view mirror.
To display the rear view image on the
screen, place the selector lever in the
“R” position when the ignition switch
in the “ON” position.
If you move the selector lever out of the
“R” position, the screen returns to the
previous screen. Operating another func-
tion of the navigation system will display
another screen.
The rear view monitor system is a supple-
ment device intended to assist back up.
When backing up, be sure to check be-
hind and all around the vehicle visually.
CAUTION
Never depend on the rear view
monitor system entirely when back-
ing up. Always make sure your in-
tended oath is clear.
Use caution just as you would when
backing up any vehicle.
Never back up while looking only at
the screen. The image on the
screen is different from actual con-
ditions. Depicted distances between
objects and flat surfaces will differ
from actual distances. If you back
up while looking only at the screen,
you may hit a vehicle, a person or
an object. When backing up, be
sure to check behind and all around
the vehicle visually and with mir-
rors before proceeding.
Do not use the system when the
back door is not completely closed.
