ble during braking.
Vehicles with vehicle stability control sys-
tem—
The light comes on when the engine
switch is turned to the “ON” position. If
the anti−lock brake system and the brake
assist system work properly, the light
turns off after a few seconds. Thereafter,
if either of the system malfunctions, the

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.

DO−IT−YOURSELF MAINTENANCE: Engine and Chassis273
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.
