“ABS” warning light
The light comes on when the ignition key
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 systems malfunctions, the light
comes on again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
following systems do not operate, but the
brake system still operates conventionally.
Anti lock brake system
Traction control system
(two wheel drive models)
Active traction control system
(four wheel drive models)
Vehicle stability control system
Downhill assist control system
(four wheel drive models)
Hill start assist control system
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti lock brake system does not operate
so that the wheels will lock up during a
sudden braking or braking on slippery
road surfaces. “VSC TRAC” warning light may come on
with the “ABS” warning light (brake assist
system warning light) when there is a mal-
function somewhere in the anti lock brake
system (brake assist system).
If either of the following conditions oc-
curs, this indicates a malfunction some-
where in the components monitored by
the warning light system. Contact your
Toyota dealer as soon as possible to
service the vehicle.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion, or remains on.
The light comes on while you are dri-
ving.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Toyota dealer.
In this case, not only the anti lock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
Either of the following conditions may
occur, but do not indicate a malfunc-
tion:
The light may stay on for about 60
seconds after the ignition key is turned
to the “ON” position. It is normal if it
turns off after a while.
Depressing the brake pedal repeatedly
may turn on the light. It is normal if it
turns off after a few seconds.
DRUM IN DISC TYPE PARKING BRAKE
SYSTEM
Your vehicle has a drum in disc type
parking brake system. This type of brake
system n eeds bedding down of the brake
shoes periodically or whenever the parking
brake shoes and/or drums are replaced.

Your new vehicle carries theft preven-
tion labels which are approximately 56
mm (2.20 in.) by 16 mm (0.63 in.).
The purpose of these labels is to reduce
the incidence of vehicle thefts by fac ilitat-
ing the tracing and recovery of parts from
stolen vehicles. The label is designed so
that once it is applied to a surface, any
attempt to remove it will result in destroy-
ing the integrity of the label. Transferring
these labels intact from one part to anoth-
er, will be impossible.
NOTICE
You should not attempt to remove the
theft prevention labels as it may vio-
late certain state or federal laws.
CAUTION
Do not modify the suspension/chassis
with lift kits, spacers, springs, etc. It
can cause dangerous handling charac-
teristics resulting in loss of control.
Determine what kind of tires your ve-
hicle is originally equipped with.
1. Summer tires
Summer tires are high speed capab ility
tires best suited to highway driving under
dry conditions.
Since summer tires do not have the same
traction performance as snow tires, sum-
mer tires are inadequate for driving on
snow covered or icy roads. For driving on
snow covered or icy roads, we recom-
mend using snow tires. If installing snow
tires, be sure to replace all four tires.
2. All season tires
All season tires are designed to provide
better traction in snow and to be adequate
for driving in most winter conditions, as
well as for use all year round.
All season tires, however, do not have
adequate traction performance compared
with snow tires in heavy or loose snow.
Also, all season tires fall short in accel-
eration and handling performance
compared with summer tires in highway
driving.

CAUTION
Before driving, make sure all the
tools, jack and flat tire are securely
in place in their storage location to
reduce the possibility of personal in-
jury during a collision or s udden
braking.
If your vehicle becomes stuck in snow,
mud, sand, etc., then you may attempt
to rock the vehicle free by moving it
forward and backward.
Turn off the traction control system to
become unstuck to allow the tires to
spin enough to remove the vehicle from
the obstruction. (For details, see “Trac-
tion control system” on page 145 in
Section 1 6.)
CAUTION
Do not attempt to rock the vehicle
free by moving it forward and back-
ward if people or objects are any-
where near the vehicle. During the
rocking operation the vehicle may
suddenly move forward or backward
as it becomes unstuck, causing injury
or damage to nearby people or ob-
jects.
NOTICE
If you rock your vehicle, observe the
following precautions to prevent dam-
age to the transmission and other
parts.
Do not depress the accelerator ped-
al while shifting the selector lever
or before the transmission is com-
pletely shifted to forward or reverse
gear.
Do not race the engine and avoid
spinning the wheels.
If your vehicle remains stuck after
rocking the vehicle several times,
consider other ways such as tow-
ing.

When rotating tires, check for uneven
wear and damage. Abnormal wear is usu-
ally caused by incorrect tire pressure, im-
proper wheel alignment, out of balance
wheels, or severe braking. 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.
Also, on four wheel drive models, all
the tires must be the same brand and
have the same tread patterns.
Do not use tires other than those men-
tioned above. Do not install studded tires
without first checking local regulations for
possible restrictions.
CAUTION
Observe the following instructions.
Otherwise, an accident may occur re-
sulting in death or serious injuries.
Do not use snow tires other than
the manufacturer ’s recommended si-
ze, as this may cause dangerous
handling characteristics resulting in
loss of control.
Four wheel drive models:
Do not use snow tires of different
brands, sizes, construction or tread
patterns, as this may cause danger-
ous handling characteristics result-
ing in loss of control.
SNOW TIRE INSTALLATION
Snow tires should be installed on all
wheels.
Installing snow tires on the front w
heels
only can lead to an excessive difference
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
Do not drive with the snow tires
incorrectly inflated.
Never drive over 120 km/h (75 mph)
with any type of snow tires.

Treadwear—The treadwear grade is a
comparative rating based on the wear rate
of the tire when tested under controlled
conditions on a specified government test
course. For example, a tire graded 150
would wear one and a half (1 1/2) times
as well on the government course as a
tire graded 100. The relative performance
of tires depends upon the actual condi-
tions of their use, however, and may de-
part significantly from the norm due to
variations in driving habits, service prac-
tices and differences in road characteris-
tics and climate.
Traction AA, A, B, C— The traction
grades, from highest to lowest, are AA, A,
B, and C, and they represent the tire’s
ability to stop on wet pavement as mea-
sured under controlled conditions on spe-
cified government test surfaces of asphalt
and concrete. A tire marked C may have
poor traction performance.
Warning: The traction grade assigned to
this tire is based on braking (straight
ahead) traction tests and does not include
cornering (turning) traction. Temperature A, B, C—
The temperature
grades are A (the highest), B, and C,
representing the tire’s resistance to the
generation of heat and its ability to dissi-
pate heat when tested under controlled
conditions on a specified indoor laboratory
test wheel. Sustained high temperature
can cause the material of the tire to de-
generate and reduce tire life, and exces-
sive temperature can lead to sudden tire
failure. The grade C corresponds to a lev-
el of performance which all passenger car
tires must meet under the Federal Motor
Vehicle Safety Standard No.109. Grades B
and A represent higher levels of perfor-
mance on the laboratory test wheel than
the minimum required by law.
Warning: The temperature grades for this
tire are established for a tire that is prop-
erly inflated and not overloaded. Exces-
sive speed, underinflation, or excessive
loading, either separately or in combina-
tion, can cause heat buildup and possible
tire failure.
