Traction control system
The traction control system automatical-
ly helps control the spinning of front
wheels when the vehicle is started or
accelerated on slippery road surfaces.
When the engine switch is turned to the
“ON” position, the system automatically
turns on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power against front 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.
MS16014
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.
When the traction control system isoper-
ating, the following conditions occur:
DThe system controls the spinning of the
front wheels. At this time, the slip indi-
cator light blinks.
DYou may feel vibration or noise in your
vehicle, caused by operation of the
brakes. This indicates the system is
functioning properly.
The slip indicator light comes on for a few
seconds when the engine switch is turned
to the “ON” position. If the indicator light
does not come on when the engine switch
is turned on, contact any authorized Toyo-
ta dealer or repairer, or another duly qual-
ified and equipped professional.

“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.

STARTING AND DRIVING215
Winter driving tips
Make sure your coolant is properly pro-
tected against freezing.
Only use “Toyota Super Long Life Coolant”
or similar high quality ethylene glycol
based non−silicate, non−amine, non−nitrite,
and non−borate coolant with long−life hy-
brid organic acid technology. (Coolant with
long−life hybrid organic acid technology is
a combination of low phosphates and or-
ganic acids.)
See “Checking the engine coolant level”
on page 267 in Section 7−2 for details of
coolant type selection.
“Toyota Super Long Life Coolant” is a mix-
ture of 50% coolant and 50% deionized
water. This coolant provides protection
down to about−35_C(−31_F).
NOTICE
Do not use plain water alone.
Check the condition of the battery and
cables.
Cold temperatures reduce the capacity of
any battery, so it must be in top shape
to provide enough power for winter start-
ing. Section 7−3 tells you how to visually
inspect the battery. Any authorized Toyota
dealer or repairer, or another duly quali-
fied and equipped professional, will be
pleased to check the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See page 264 in Section 7−2forrecom-
mended viscosity. Leaving a heavy sum-
mer oil in your vehicle during winter
months may make starting harder. If you
are not sure about which oil to use, call
any authorized Toyota dealer or repairer,
or another duly qualified and equipped
professional, they will be pleased to help.
Keep the door locks from freezing.
Squirt lock de−icer or glycerine into the
locks to keep them from freezing.Use a washer fluid containing an anti-
freeze solution.
This product is available at any authorized
Toyota dealer or repairer and most auto
parts stores or another qualified profes-
sional. Follow the manufacturer ’s direc-
tions for how much to mix with water.
NOTICE
Do not use engine antifreeze or any
other substitute because it may dam-
age your vehicle’s paint.
Do not use your parking brake when
there is a possibility it could freeze.
When parking, put the transmission into
“M(1)”, “E(1)” or “R” (multi−mode manual
transmission), or into first or reverse
(manual transmission) and block the rear
wheels. Do not use the parking brake,
snow or water accumulated in and around
the parking brake mechanism may freeze,
making it hard to release.
Keep ice and snow from accumulating
under the fenders.
Ice and snow built up under your fenders
can make steering difficult. During bad
winter driving, stop and check under the
fenders occasionally.
Depending on where you are driving,
we recommend you carry some emer-
gency equipment.
Some of the things you might put in the
vehicle are tire chains, a window scraper,
a bag of sand or salt, flares, a small
shovel, jumper cables, etc.

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
To y o t a .
Using tires whose previous history is un-
known is a risk.
Toyota recommends all tires be re-
placed at a time as a set.
See “If you have a flat tire” on page 226
in Section 4 for tire change procedure.

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.

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.
