CAUTION
Always keep your foot on the brake
pedal while stopped with the engine
running. This prevents the vehicle
from creeping.
NOTICE
Do not hold the vehicle on an up-
grade with the accelerator pedal. It
can cause the transmission to over-
heat. Always use the brake pedal or
parking brake.
(i) Rocking your vehicle if stuck
CAUTION
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. Do
not attempt this procedure if people
or objects are anywhere near the ve-
hicle. During the rocking operation
the vehicle may suddenly move for-
ward or backward as it becomes un-
stuck, causing injury or damage to
nearby people or objects.
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.

The traction control system automatical-
ly helps prevent the spinning of front
wheels when the vehicle is started or
accelerated on slippery road surfaces.
When the ignition key is turned to “ON”,
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.
NORMAL DRIVING MODE
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
is started. This means that the traction
control system is in the self check mode,
but does not indicate a malfunction. When the traction control system is oper-
ating, the following conditions occur:
The system controls the spinning of the
front wheels. At this time, the slip indi-
cator light blinks.
You 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 ignition key is turned
to “ON”. If the indicator light does not
come on when the ignition is turned on,
contact your Toyota dealer.

TRACTION CONTROL OFF MODE
If your wheels get stuck in a ditch
when you are driving on a severe off
road and sand, turn off the traction
control system. This system that con-
trols engine performance interferes with
the process of freeing your wheels.
To turn off: Push “TRAC OFF” switch.
The “TRAC OFF” indicator light will come
on.
To turn on: Push “TRAC OFF” switch
once again.
The “TRAC OFF” indicator light will go off. “TRAC OFF” indicator light comes on for
a few seconds when the ignition key is
turned to “ON”. It will come on again
when you push the “TRAC OFF” switch to
turn off the system.
In the following cases, contact your Toyota
dealer:
The indicator light does not come on
when the ignition key is turned “ON”.
The indicator light remains on after the
ignition is turned on.
The indicator light comes on with the
normal driving mode while driving.
“VSC” warning light
This light warns that there is a problem
somewhere in the traction control system
or the vehicle skid control system.
The light will come on when the ignition
key 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 ignition key is turned to “ON”.
The warning light remains on after the
ignition key is turned to “ON”.
The warning light comes on while driv-
ing. The vehicle skid control system helps
provide integrated control of the sys-
tems such as an anti lock brake sys-
tem, brake assist system, traction con-
trol, engine control, etc. This system
automatically controls the output of the
brakes or engine to help prevent the
vehicle from skidding when cornering
on a slippery road surface or abrupt
steering wheel operation occurs.
This 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
is started. This means that the system is
in the self check mode but does not indi-
cate a malfunction.
CAUTION
Do not rely excessively on the ve-
hicle skid control system. Even if
the vehicle skid control system is
operating, you must always drive
carefully and attentively to avoid
serious injury. Reckless driving will
result in an unexpected accident. If
the slip indicator light flashes,
sounding an alarm sounds, special
care should be taken while driving.
Only 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 skid control sys-
tem may not function correctly.
When replacing the tires or wheels,
contact your Toyota dealer. (See
“Checking and replacing tires” in
Section 7 2.)

TIRE PRESSURE WARNING SYSTEM
RESET SWITCH
Pushing this reset switch after replac-
ing or rotating tires or wheels memo-
ries the present tire condition as a
standard.
After replacing or rotating the tires or
wheels, perform the initial adjustment as
follows.
1. Park the vehicle at a safe place and apply the parking brake. Stop the en-
gine.
2. Adjust pressures of all the installed tires to the specified level. (See “Tires”
in Section 8.)
3. Turn the ignition key to “ON”. 4. With the vehicle stopped, push the re-
set switch on the left lower instrument
panel and hold it until the low tire
pressure warning light blinks for three
times.
5. The initial adjustment is completed af- ter driving at the speeds of 30 km/h
(19 mph) or over for about total 8
hours, when the tire pressure warning
system detects the normal tire pressur-
es.
Do not push the reset switch without ad-
justing the tire pressure to the specified
level. Otherwise, the low tire pressure
warning light may not come on even if the
tire pressure is low, or it may come on
when the tire pressure is actually normal.
If you push the reset switch while the
vehicle is moving, the initial adjustment is
not performed.
If the low tire pressure warning light does
not blink when you push and hold the
reset switch, have the low pressure warn-
ing system checked at your Toyota dealer.Ty p e A

The tandem master cylinder brake system
is a hydraulic system with two separate
sub systems. If either sub system s hould
fail, the other will still work. However, the
pedal will be harder to press, and your
stopping distance will be longer. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses engine vacuum to
power assist the brakes. If the engine
should quit while you are driving, you can
bring the vehicle to a stop with normal
pedal pressure. There is enough reserved
vacuum for one or two stops—but no
more!
CAUTION
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your reserved vacu-
um.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hard, much harder than nor-
mal. And your braking distance will
be longer.
ANTI LOCK BRAKE SYSTEM (with
“ABS” warning light)
The anti lock brake system is designed
to help prevent lock up of the wheels
during a sudden braking or braking on
slippery road surfaces. This assists in
providing directional stability and steer-
ing performance of the vehicle under
these circumstances.
Effective way to press the ABS brake
pedal: When the anti lock brake system
function is in action, you may feel the
brake pedal pulsating and hear a noise.
In this situation, to let the anti lock
brake system work for you, just hold the
brake pedal down more firmly. Do not
pump the brake in a panic stop. This
will result in reduced braking performan-
ce.
The anti lock brake system becomes op-
erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph).
Depressing the brake pedal on slippery
road surfaces such as on the manhole
cover, the steel plate under the construc-
tion, joints in the bridge, etc. on a rainy
day tends to activate the anti lock brake
system.
You may hear a click or motor sound in
the engine compartment for a few seconds
when the engine is started or just after
the vehicle is started. This means that the
anti lock brake system is in the self
check mode, and does not indicate a mal-
function.
Brake system

2312002 MY SIENNA_U (OM45407U)
When the anti lock brake system is ac-
tivated, the following conditions may
occur. They do not indicate a malfunc-
tion of the system:
You 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.
At the end of the anti lock brake sys-
tem activation, the brake pedal may
move a little forward.
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 tires 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 the 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:
Driving on rough, gravel or snow
covered roads.
Driving with tire chains installed.
Driving over the steps such as the
joints on the road.
Driving 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.

“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
anti lock brake system, the brake assist
system, the traction control system and
the vehicle skid control system do not
operate, but the brake system still oper-
ates conventionally.
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 could lock up during
a sudden braking or braking on slippery
road surfaces. If either of the following conditions
occurs, this indicates a malfunction
somewhere in the parts 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 driv-
ing.
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.

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
Do not mix summer and all season
tires on your vehicle as this can
cause dangerous handling charac-
teristics, resulting in loss of con-
trol.
Do not use tires other than the
manufacturer ’s designated tires, and
never mix tires or wheels of the
sizes different from the originally
equipped tires and wheels.
