2006 TOYOTA LAND CRUISER tire type

The vehicle stability control system
helps provide integrated control of the
systems such as antilock brake, trac-
tion control, engine control, etc. This
system automatically controls the out-
put of the brakes or engine to help
prevent the vehicle from skidding under
adverse conditions.
The system activates when the vehicle
speed is about 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 ve-
hicle stability control system is in the
self−check mode and does not indicate a
malfunction.CAUTION
Active traction control system, ve-
hicle stability control system and
antilock brake system are electron-
ic systems designed to help the
driver maintain control under ad-
verse conditions. They are not a
substitute for safe driving practices.
Factors including speed, road con-
ditions and driver steering input
can all affect whether active trac-
tion control system, vehicle stability
control system and antilock brake
system will be effective in prevent-
ing a loss of control. Always keep
safety driving in mind. If the slip
indicator light flashes, sounding an
alarm, special care should be taken
while driving.
Only use tires of specified size. The
size, manufacturer, 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 your Toyota dealer. (See
“Checking and replacing tires” on
page 323.)

When the “ABS” warning light comes on,
the vehicle stability control system is not
operating.
The “VSC/TRAC” warning light and “VSC
OFF” indicator light will come on when the
ignition key is turned “ON”, and will go off
after a few seconds.
The “VSC/TRAC” warning light and “VSC
OFF” indicator light may stay on for 60
seconds after the ignition key is turned to
“ON” position. It is normal if they go off
after a few seconds.
Depressing the brake pedal repeatedly
may turn on the lights. It is normal if they
go off after a few seconds.
When the “VSC/TRAC” warning light and
“VSC OFF” indicator light come on, the
vehicle stability control system is not op-
erating, but there is no problem if you
continue to drive.
In the following cases, contact your Toyota
dealer:
The “VSC/TRAC” warning light, “VSC
OFF” indicator light and slip indicator
light do not come on after the ignition
key is turned “ON”.
The “VSC/TRAC” warning light and
“VSC OFF” indicator light remain on af-
ter the ignition key is turned “ON”.
The “VSC OFF” indicator light comes
on while driving without pushing the
center differential lock switch.

Low tire pressure warning light
The light warns you that the tire infla-
tion pressure is low.
The low tire pressure warning light comes
on when the ignition key is turned to the
“ON” position and goes off after a few
seconds. This means the low tire pres-
sure warning light is operating properly.
If the tire inflation pressure becomes low,
the light comes on again.If the low tire pressure warning light does
not go off or comes on during driving, it
indicates that tire inflation pressure is low.
Make sure there is no flat tire. If the
light comes on again even after tire infla-
tion pressure adjustment, you may have a
flat tire. If there is not adequate air
pressure in the tires, the light will not go
off.
The light may turn on due to natural
causes such as natural air leaks or tire
inflation pressure changes caused by tem-
perature. In this case, adjusting the tire
inflation pressure will turn off the light.
The tire pressure warning system is not
a substitute for checking tire inflation
pressure.
For details about adjusting the tire
inflation pressure, see “Checking tire
inflation pressure” on page 320.
If the low tire pressure warning light
comes on, the action you must take is
different depending on the type of tires
used.

Limitedslip differential
Some Toyotas are equipped with a lim-
ited−slip differential. If one of the rear
wheels begins to spin, the limited −slip dif-
ferential is designed to aid traction by
automatically transmitting driving force to
the other rear wheel. If you are not sure
whether your vehicle is equipped with one,
you can ask your Toyota dealer.
CAUTION
Do not start or run the engine while
your vehicle is supported by a jack.
The vehicle could be driven off the
jack and could pose a danger or re-
sult in serious injury.
NOTICE
Use only a spare tire of the same
size, construction and load capacity
as the original tires on your Toyota
because damage to the limitedslip
differential could possibly occur with
another tire type.
The vehicle identification number (VIN)
is the legal identifier for your vehicle.
This number is on the left top of the
instrument panel, and can be seen
through the windshield from outside.
This is the primary identification number
for your Toyota. It is used in registering
the ownership of your vehicle.

The vehicle identification number (VIN) is
also on the Certification Label.

Types of tires
Determine what kind of tires your
vehicle is originally equipped with.1. Summer tires
Summer tires are high −speed capabil-
ity tires best suited to highway driving
under dry conditions.
Since summer tires do not have the
same traction performance as snow
tires, summer tires are inadequate for
driving on snow −covered or icy roads.
For driving on snow −covered or icy
roads, we recommend using snow
tires. If installing snow tires, be sure
to replace all four tires.
2. All season tires
All season tires are designed to pro-
vide 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 acceleration and handling
performance compared with summer
tires in highway driving.
The details about how to distinguish
summer tires from all season tires are
described on page 238.
CAUTION

Do not mix summer and all sea-
son tires on your vehicle as
this can cause dangerous han-
dling characteristics, resulting
in loss of control.
 Do not use tires other than the
manufacturer’s designated
tires, and do not mix tires or
wheels of the sizes different
from the originally equipped
tires and wheels as this could
result in loss of control and
could cause death or serious
injury.
