The vehicle stability control system
helps provide integrated control of the
systems such as an antilock brake
system, brake assist system, traction
control, engine control, etc. This sys-
tem automatically controls the brakes
and engine to help prevent the vehicle
from skidding when cornering on a slip-
pery road surface or operating steering
wheel abruptly.
The vehicle stability control system is acti-
vated 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 just after
the vehicle begins to move. This means
that the system is in the self−check mode,
but does not indicate a malfunction.CAUTION
Do not rely excessively on the ve-
hicle stability control system. Even
if the vehicle stability control sys-
tem is operating, you must always
drive carefully and attentively to
avoid serious injury. Reckless driv-
ing will result in an unexpected ac-
cident. If the slip indicator light
flashes, an alarm sounds, 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 526 in Section 72.)
In situations where the road surface
is covered with ice or snow, your
vehicle should be fitted with snow
tires or tire chains.
If the vehicle is going to skid during driv-
ing, the slip indicator light blinks and an
alarm sounds intermittently. Special care
should be taken while driving.
The slip indicator light comes on for a few
seconds when the engine switch is turned
to “ON”. If the indicator light does not
come on when the engine switch is turned
on, contact your Toyota dealer.

“VSC” warning light
This light warns that there is a problem
somewhere in the vehicle stability control
system or the traction control system.
The light will come on when the engine
switch is turned to “ON” and will go off
after a few seconds.
If the light comes on while driving, the
system does not work. However, as con-
ventional braking operates when applied,
there is no problem to continue your driv-
ing.In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the engine switch is turned to
“ON”.
The warning light remains on after the
engine switch is turned to “ON”.
The warning light comes on while driv-
ing.
Tw o −wheel drive models only—The “TRAC
OFF” indicator light will come on when the
“VSC” warning light comes on even if the
“TRAC OFF” switch is not pushed. The tire pressure warning system warns
you that the tire inflation pressure is
low.
The tire pressure warning system is not
a substitute for checking normal tire infla-
tion pressure. Check the tire inflation
pressure with a tire pressure gauge regu-
larly.
CAUTION
The warning system may not activate
immediately if a blowout or sudden
air leakage should occur.

The tire pressure warning light comes on
when the engine switch is in “ON” position
and goes off after a few seconds. This
means the tire pressure warning system is
operating properly. If the tire inflation pres-
sure becomes low, the light comes on
again. In this case, adjusting the tire infla-
tion pressure will turn off the light after
several minutes. If the light comes on
after blinking for 1 minute, the tire pres-
sure warning system is not working prop-
erly.Indicator

CAUTION
If the tire pressure warning light
comes on, be sure to observe the
following precautions. Failure to do
so could cause loss of vehicle control
and result in death or serious injury.
Vehicles with runflat tires:
Decelerate to the lowest appropriate
speed as soon as possible. Do not
drive over 90 km/h (55 mph).
Check and adjust the tire inflation
pressure immediately.
If the tire pressure warning light
comes on even after tire inflation
pressure adjustment, it is probable
that you have a flat tire. Have the
tire replaced by the nearest Toyota
dealer.
Avoid abrupt maneuvering and brak-
ing. If the vehicle tires deteriorate,
you could lose control of the steer-
ing wheel or the brakes.
Vehicles with standard tires:
Stop your vehicle in a safe place as
soon as possible. Adjust the tire
inflation pressure immediately.
If the tire pressure warning light
comes on even after tire inflation
pressure adjustment, it is probable
that you have a flat tire. Check the
tires. If the tire is flat, change to
the spare tire and have the flat tire
repaired by the nearest Toyota deal-
er.
Avoid abrupt maneuvering and bra-
king. If the vehicle tires deteriorate,
you could lose control of the steer-
ing wheel or the brakes.

The tire pressure warning light may turn
on due to natural causes such as natural
air leaks or tire inflation pressure changes
caused by temperature. In this case, ad-
justing the tire inflation pressure will turn
off the light after several minutes.
Pushing the tire pressure warning reset
switch should not turn off the tire pressure
warning light. Adjusting the tire inflation
pressure will turn off the light.
The compact spare tire is not equipped
with the tire pressure warning valve and
transmitter. If a tire goes flat, the warning
light will not turn off even though the flat
tire is replaced with the spare tire. Re-
place the spare tire with the repaired tire
and adjust the proper tire inflation pressur-
e. The tire pressure warning light will turn
off after several minutes.CAUTION
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard
or tire inflation pressure label (tire
and load information label). (If your
vehicle has tires of a different size
than the size indicated on the vehicle
placard or tire inflation pressure label
(tire and load information label), you
should determine the proper tire infla-
tion pressure for those tires.)
As an added safety feature, your ve-
hicle has been equipped with a tire
pressure monitoring system (TPMS–
tire pressure warning system) that il-
luminates a low tire pressure telltale
(tire pressure warning light) when one
or more of your tires is significantly
underinflated. Accordingly, when the
low tire pressure telltale (tire pres-
sure warning light) illuminates, you
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure. Driving on a sig-
nificantly underinflated tire causes
the tire to overheat and can lead to
tire failure. Underinflation also re-
duces fuel efficiency and tire tread
life, and may affect the vehicle’s han-
dling and stopping ability.

2008 SIENNA from Aug. ’08 Prod. (OM45455U)
Please note that the TPMS (tire pres-
sure warning system) is not a substi-
tute for proper tire maintenance, and
it is the driver ’s responsibility to
maintain correct tire pressure, even if
underinflation has not reached the
level to trigger illumination of the
TPMS low tire pressure telltale (tire
pressure warning light).Your vehicle has also been equipped
with a TPMS (tire pressure warning
system) malfunction indicator to indi-
cate when the system is not operat-
ing properly. The TPMS (tire pressure
warning system) malfunction indicator
is combined with the low tire pres-
sure telltale (tire pressure warning
light). When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated. This
sequence will continue upon subse-
quent vehicle startups as long as
the malfunction exists. When the mal-
function indicator is illuminated, the
system may not be able to detect or
signal low tire pressure as intended.TPMS (tire pressure warning system)
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS (tire pressure warning sys-
tem) from functioning properly. Al-
ways check the TPMS (tire pressure
warning system) malfunction telltale
after replacing one or more tires or
wheels on your vehicle to ensure that
the replacement or alternate tires and
wheels allow the TPMS (tire pressure
warning system) to continue to func-
tion properly.

REPLACING TIRES AND WHEELS
When replacing the tires and wheels, be
sure to install tire pressure warning valves
and transmitters. ID codes on the tire
pressure warning valves and transmitters
are registered in the tire pressure warning
computer. When replacing a tire pressure
warning valve and transmitter, it is neces-
sary to register the ID code of tire pres-
sure warning valve and transmitter. Have
the ID code registered by your Toyota
dealer.
If the ID code is not registered, the sys-
tem will not work properly. After driving
for about 20 minutes, the tire pressure
warning light comes on after blinking for
1 minute to indicate a system malfunction.
NOTICE
When the tires or tire pressure warn-
ing valves and transmitters must be
replaced, have them replaced by your
Toyota dealer. The tire pressure warn-
ing valves and transmitters will be
affected by the installation or removal
of tires.
TIRE PRESSURE WARNING RESET
SWITCH
When initializing the system, the present
tire inflation pressure is stored as stan-
dard. The tire pressure warning system
determines decreased air pressure by
comparing the present and the standard
tire inflation pressures. When you change
the set tire inflation pressure, it is neces-
sary to initialize the tire pressure warning
system.
When changing the tire size.To initialize the system, perform the fol-
lowing:
1. Park the vehicle in a safe place and turn the engine switch off.
2. Adjust the pressure of all the installed tires to the specified cold tire inflation
pressure level. (See “Tires” on page
553 in Section 8.)
3. Turn the engine switch is in “ON” posi- tion.
4. Push and hold the tire pressure warn- ing reset switch until the tire pressure
warning light blinks slowly three times.
5. Wait for several minutes with the en- gine switch “ON”, and then turn the
engine switch to the “ACC” or “LOCK”
position.
If you push the tire pressure warning re-
set switch while the vehicle is moving,
initialization is not performed.
If you push the tire pressure warning re-
set switch accidentally and initialization is
performed, adjust the tire inflation pres-
sure to the specified level and initialize
the system again.

221
2008 SIENNA from Aug. ’08 Prod. (OM45455U)
If the tire pressure warning light does not
blink slowly three times when you push
and hold the tire pressure warning reset
switch, initialization has failed and the tire
pressure warning system may not work
properly. In this case, initialize the system
again. If initialization cannot be performed,
have the system checked at your Toyota
dealer.
CAUTION
Do not push the tire pressure warn-
ing reset switch without first adjust-
ing the tire inflation pressure to the
specified level. Otherwise, the tire
pressure warning light may not come
on even if the tire inflation pressure
is low, or it may come on when the
tire inflation pressure is actually nor-
mal.
