“VSC” warning light
This light warns that there is a problem
somewhere in the traction control system
or the vehicle stability control system.
The light will come on when the engine
switch is turned to the “ON” position and
will go off after a few seconds.
If the light comes on while driving, the
systemdoes not work. However, as con-
ventional braking operates when applied,
there is no problem to continue your driv-
ing.
In the following cases, contact any autho-
rized Toyota dealer or repairer, or another
duly qualified and equipped professional:
DThe warning light does not come on
after the engine switch is turned to the
“ON” position.
DThe warning light remains on after the
engine switch is turned to the “ON”
position.
DThe warning light comes on while driv-
ing.The vehicle stability controlsystem au-
tomatically controls the brakes and en-
gine to help prevent the vehicle from
skidding when cornering on a slippery
road surface or operating steering
wheel abruptly.
The vehicle stability control system is acti-
vated when the vehicle speed is more
than 15 km/h (9 mph).
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 sys-
tem is in the self−check mode but does
not indicate a malfunction.
CAUTION
DDo not rely excessively on the ve-
hicle stability controlsystem. Even
if the system is operating, you
must always drive carefully and at-
tentively. Reckless driving will re-
sult in an unexpected accident and
cause death or serious injury. If the
slip indicator light blinks, and spe-
cial care should be taken while
driving.
DOnly use tires of specified size. The
size, manufacture, brand and tread
pattern for all 4 tires should be the
same. If you use the tires other
than specified, or different type or
size, the vehicle stability control
system may not function correctly.
When replacing the tires or wheels,
contact any authorized Toyota deal-
er or repairer, or another duly quali-
fied professional. (See “Checking
and replacing tires” on page 270 in
Section 7−2.)
DIn situations where the road surface
is covered with ice or snow, your
vehicle should be fitted with snow
tire or tire chains.

INFORMATION BEFORE DRIVING YOUR TOYOTA201
DYou may hear the anti−lock brake sys-
tem operating and feel the brake pedal
pulsating and the vibrations of the ve-
hicle body and steering wheel. You
may also hear the motor sound in the
engine compartment even after the ve-
hicle is stopped.
DAt the end of the anti−lock brake sys-
tem activation, the brake pedal may
movealittleforward.
CAUTION
Do not overestimate the anti−lock
brake system: Although the anti−lock
brake system assists in providing ve-
hicle control, it is still important to
drive with all due care and maintain
a moderate speed and safe distance
from the vehicle in front of you, be-
cause there are limits to the vehicle
stability and effectiveness of steering
wheel operation even with the anti−
lock brake system on.
If tire grip performance exceeds its
capability, or if hydroplaning occurs
during high speed driving in the rain,
the anti−lock brake system does not
provide vehicle control.
Anti−lock brake system is not de-
signed to shorten the stopping dis-
tance: Always drive at a moderate
speed and maintain a safe distance
from the vehicle in front of you.
Compared with vehicles without an
anti−lock brake system, your vehicle
may require a longer stopping dis-
tance in the following cases:
DDriving on rough, gravel or snow−
covered roads.
DDriving with tire chains installed.
DDriving over the steps such as the
joints on the road.
DDriving on roads where the road
surface is pitted or has other differ-
ences in surface height.
Install all 4 tires of specified size at
appropriate pressure: The anti−lock
brake system detects vehicle speeds
using the speed sensors for respec-
tive wheels’ turning speeds. The use
of tires other than specified may fail
to detect the accurate turning speed
resulting in a longer stopping dis-
tance.

CORROSION PREVENTION AND APPEARANCE CARE247
Use mud shields on your wheels.If you
drive on salted or gravel roads, mud
shields help protect your vehicle. Full−size
shields, which come as near to the ground
as possible, are the best. We recommend
that the fittings and the area where the
shields are installed be treated to resist
corrosion. Your authorized Toyota dealer
or repairer, or another duly qualified and
equipped professional will be happy to as-
sist in supplying and installing the shields
if they are recommended for your area.
Keep your vehicle in a well ventilated
garage or a roofed place. Do not park
your vehicle in a damp, poorly venti-
lated garage.If you wash your vehicle in
the garage, or if you drive it covered with
water or snow, your garage may be so
damp as to cause corrosion. Even if your
garage is heated, a wet vehicle can cor-
rode if the ventilation is poor.Washing your Toyota
Keep your vehicle clean by regular
washing.
NOTICE
The following cases may cause weak-
ness to the paint or corrosion to the
body and components. (aluminum
wheels etc.) Wash your vehicle as
soon as possible.
zAfter driving near the sea coast
zAfter driving on salted roads
zIf you see coal tar or tree sap on
the paint surface
zIf you see dead insects, insect
droppings or bird droppings on the
paint
zAfter driving in an area contami-
nated with soot, oily smoke, mine
dust, iron powder or chemical sub-
stances
zIf the vehicle becomes heavily
soiled in dust or mud
zIf liquids such as benzene and gas-
oline are spilled on the paint sur-
face
If the paint is chipped or scratched,
have it repaired immediately.
To prevent the wheels from corroding,
remove any dirt and store in a place
with low humidity when storing the
wheels.

NOTICE
Tires may have damage to its tire
wheel when receiving impact from the
road surface. Therefore, pay attention
to the following.
zBe sure to use with proper tire
inflation pressure. If the tire infla-
tion pressure is low, the tire may
have greater damage. For detailed
information about tire inflation pres-
sure, see page 299.
zAvoid driving onto high, sharp−
edged objects and other road haz-
ards. Failure to do so can lead to
severe tire damage.
The effectiveness of snow tires is lost
if the tread wears down below 4 mm
(0.16in.).
If you have tire damage such as cuts,
splits, cracks deep enough to expose
the fabric, or bulges indicating internal
damage, the tire should be replaced.
If a tire often goes flat or cannot be prop-
erly repaired due to the size or location
of a cut or other damage, it should be
replaced. If you are not sure, consult with
any authorized Toyota dealer or repairer,
or another duly qualified and equipped
professional.
If air loss occurs while driving, do not
continue driving. Driving even a short dis-
tance could damage a tire beyond repair.
Any tires which are over 6 years old
must be checked by a qualified techni-
cian even if damage is not obvious.
Tires deteriorate with age even if they
have never or seldom been used.
This applies also to the spare tire and
tires stored for future use.REPLACING YOUR TIRES
When replacing a tire, use a tire of the
same size and construction, and the
same or greater load capacity as the
originally installed tires.
Using any other size or type of tire may
seriously affect handling, ride, speedome-
ter/odometer calibration, ground clearance,
and clearance between the body and tires
or snow chains.
CAUTION
Observe the following instructions.
Otherwise, an accident may occur re-
sulting in death or serious injuries.
DDo not mix radial, bias belted, or
bias−ply tires on your vehicle, as
this may cause dangerous handling
characteristics resulting in loss of
control.
DDo not use tires other than the
manufacturer ’s recommended size,
as this may cause dangerous han-
dling characteristics resulting in
loss of control.
DDo not mix tires of different makes,
models or tread patterns, and do
not mix tires of remarkably different
treadwear. This may cause danger-
ous handling characteristics result-
ing in loss of control.
Never use second−hand tires on your

Using tires whose previous history is un-
known is a risk.
Toyota recommends all tires be re-
placed at a time as a set.

WHEN TO USE SNOW TIRES OR
CHAINS
Snow tires or chains are recommended
when driving on snow or ice.
On wet or dry roads, conventional tires
provide better traction than snow tires.
SNOW TIRE SELECTION
If you need snow tires, select tires of
the same size, construction and load
capacity as the originally installed tires.
Do not use tires other than those men-
tioned above. Do not install studded tires
without first checking local regulations for
possible restrictions.
CAUTION
Do not use snow tires other than the
manufacturer ’s recommended size, as
this may cause dangerous handling
characteristics resulting in loss of
control. Otherwise, an accident may
occur resulting in death or serious
injuries.
SNOW TIRE INSTALLATION
Snow tires should be installed on all
wheels.
Installing snow tires on the front or rear
wheels only can lead to an excessive dif-
ference in road grip capability between the
front and rear tires which could cause
loss of vehicle control.
When storing removed tires, you should
store them in a cool dry place.
Mark the direction of rotation and be sure
to install them in the same direction when
replacing.
CAUTION
DDo not drive with the snow tires
incorrectly inflated.
DObserve permissible maximum
speed for your snow tires and the
legal speed limit.

TIRE CHAIN SELECTION
Use the tire chains of correct size.
For155/65R14 tires, use the following
type chains.
A Diameter of side chain:
4mm(0.16in.)
B Diameter of cross chain:
5 mm (0.20 in.)
Regulations regarding the use of tire
chains vary according to location or
type of road, so always check local reg-
ulations before installing chains.
NOTICE
If the wrong combination of tire and
chain is used, the chains could dam-
age the vehicle body.
CHAIN INSTALLATION
Install the chains on the front tires as
tightly as possible. Do not use tire
chains on the rear tires. Retighten the
chains after driving 0.5—1.0 km
(1/4—1/2 mile).
When installing chains on your tires, care-
fully follow the instructions of the chain
manufacturer.
If wheel covers are used, they will be
scratched by the chain band, so remove
the covers before putting on the chains.
CAUTION
DDo not exceed 50 km/h (30 mph) or
the chain manufacturer ’s recom-
mended speed limit, whichever is
lower.
DDrive carefully avoiding bumps,
holes, and sharp turns, which may
cause the vehicle to bounce.
DAvoid sharp turns or locked−wheel
braking as use of chains may ad-
versely affect vehicle handling.
DWhen driving with chains installed,
be sure to drive carefully. Slow
down before entering curves to
avoid losing control of the vehicle.
Otherwise an accident may occur.

Replacing wheels
WHEN TO REPLACE YOUR WHEELS
If you have wheel damage such as
bending, cracks or heavy corrosion, the
wheel should be replaced.
If you fail to replace a damaged wheel,
the tire may slip off the wheel or cause
loss of handling control.
WHEEL SELECTION
When replacing wheels, care should be
taken to ensure that the wheels are re-
placed by ones with the same load ca-
pacity, diameter, rim width, and inset
∗.
Correct replacement wheels are available
at your Toyota dealer or repairer, or
another duly qualified and equipped pro-
fessional.
∗: Conventionally referred to as “offset”.
A wheel of a different size or type may
adversely affect handling, wheel and bear-
ing life, brake cooling, speedometer/odom-
eter calibration, stopping ability, headlight
aim, bumper height, vehicle ground clear-
ance, and tire or snow chain clearance to
the body and chassis.
Replacement with used wheels is not rec-
ommended as they may have been sub-
jected to rough treatment or high mileage
and could fail without warning. Also, bent
wheels which have been straightened may
have structural damage and therefore
should not be used. Never use an inner
tube in a leaking wheel which is designed
for a tubeless tire.
CAUTION
Do not use wheels other than the
manufacturer ’s recommended size, as
this may cause dangerous handling
characteristics resulting in loss of
control. Otherwise, an accident may
occur resulting in death or serious
injuries.
Aluminum wheel precautions
DWhen installing aluminum wheels,
check that the wheel bolts are tight
after driving your vehicle the first1600
km (1000 miles).
DIf you have rotated, repaired, or
changed your tires, check that the
wheel bolts are still tight after driving
1600 km (1000 miles).
DWhen using tire chains, be careful not
to damage the aluminum wheels.
DToyota recommends the use of Toyota
genuine wheel bolts and wrench de-
signed for your aluminum wheels. Oth-
er bolts and wrenches of matching
quality can also be used.
DWhen balancing your wheels, Toyota
recommends the use of Toyota genuine
balance weights. Other balance weights
canalsobeused.
DAs with any wheel, periodically check
your aluminum wheels for damage. If
damaged, replace immediately.
