If you need to accelerate—for example,
when passing—depress the accelerator
pedal enough for the vehicle to exceed
the preset speed. When you release the
accelerator pedal, the vehicle will return to
the control prior to acceleration.
You cannot set a desired speed if the
master warning light comes on, the alarm
sounds and the display indicates one of
the warning codes “E1”, “E2” or “E3”. If
any of the above codes appears on the
display, see “VEHICLE−TO −VEHICLE
DISTANCE CONTROL MODE FAILURE
WARNING” on page 235.
CANCELLING THE
VEHICLETOVEHICLE DISTANCE
CONTROL MODE
The vehicle −to −vehicle distance control
mode may be temporarily cancelled by the
driver or by the system itself under cer-
tain circumstances. Temporary cancellation
allows the set cruising speed and vehicle −
to −vehicle distance to remain in memory.
The vehicle −to −vehicle distance control
mode can be temporarily cancelled by do-
ing the following:
Pulling the lever in the “CANCEL” di-
rection and releasing it
Depressing the brake pedal Under certain circumstances, the vehicle
−
to −vehicle distance control mode is tempo-
rarily cancelled:
When vehicle speed falls below 40
km/h (25 mph)
When vehicle stability control is acti-
vated
The “READY” indicator light comes on to
indicate that the system is still in opera-
tion.
To turn the system off, press the “ON −
OFF” button. Make sure the “CRUISE” in-
dicator light is off.
If one of the warning codes “E1”, “E2” or
“E3” appears on the display, the preset
speed automatically cancels out. See
“VEHICLE −TO −VEHICLE DISTANCE
CONTROL MODE FAILURE WARNING” on
page 235.
If the vehicle −to −vehicle distance control
mode automatically cancels out other than
for the above cases, have your vehicle
checked by your Toyota dealer at the ear-
liest opportunity. RESUMING THE VEHICLETOVEHICLE
DISTANCE CONTROL MODE
If the vehicle
−to −vehicle distance control
mode is temporarily cancelled, the cruising
speed and vehicle −to −vehicle distance can
be resumed by pushing the lever up in the
“+ RES” direction.
Vehicle speed must be above 40 km/h (25
mph).
During follow −up cruising, if there are no
vehicles ahead because they have
changed lanes, your vehicle will accelerate
gradually up to the preset speed. At this
time, pushing the lever up in the “+ RES”
direction will quickly speed up your ve-
hicle in vehicle −to −vehicle distance control
mode.

Before driving in the vehicletovehicle
distance control mode, make sure the
radar sensor glass is clean.
This product is a class I laser product
complied with 21 C.F.R part 1040.10
and 1040.11.
CAUTION
To ensure that dynamic laser cruise
control will function properly while
driving, observe the following:
Always keep the laser radar sensor
glass clean. When cleaning, use a
soft cloth and be careful not to
damage the sensor.
Avoid strong impacts around the la-
ser radar sensor. An incorrect laser
radar sensor alignment will result in
system malfunction. A special de-
vice is required to adjust the laser
radar sensor alignment. Be sure to
have the sensor adjusted by your
Toyota dealer.
Do not affix a sticker (including a
transparent sticker) or attach an ac-
cessory around the laser radar sen-
sor.
VEHICLETOVEHICLE DISTANCE
CONTROL MODE FAILURE WARNING
If there is trouble somewhere in the dy-
namic laser cruise control while the ve-
hicle−to −vehicle distance control mode is
on, the master warning light comes on
and the alarm sounds, and one of the
warning codes “E1”, “E2” or “E3” will ap-
pear on the display. Dynamic laser cruise
control is automatically cancelled.
If “E3” appears on the display, the
“CRUISE” indicator light in the instrument
cluster also flashes. If “E1” appears on the display,
the sys-
tem cannot easily measure the vehicle −to −
vehicle distance because of a dirty laser
radar sensor glass while the dynamic la-
ser cruise control is on.
If this code appears, clean the sensor
glass with a soft cloth and try setting the
preset speed again. If the dirt is removed
without cleaning, the system will automati-
cally enter the ready mode.
If the system does not enter the ready
mode even after cleaning or the code re-
mains on the display, the system might be
malfunctioning. Although there is no prob-
lem to continue driving, please contact
your Toyota dealer.
CAUTION
Always keep the sensor glass and
never allow it to be covered with
icicle or any substance, so it can de-
tect the vehicle in front.

2007 SIENNA from Oct. ’06 Prod. (OM45437U)
If “E2” appears on the display, the sys-
tem cannot easily measure the vehicle −to −
vehicle distance because of the following
conditions:
The wipers are operating at high or low
speeds
Direct sunlight from the front
It is difficult to make a measurement
because of bad weather (such as rainy,
foggy, or snowy weather)
In the following cases, dynamic laser
cruise control switches to the ready mode:
The wipers are stopped or are
switched to intermittent operation.
No direct sunlight from the front
In the above conditions, push the lever up
in the “+ RES” direction and release it.
Dynamic laser cruise control will be re-
stored. If the setting operation cannot be
performed or if the warning code still ap-
pears even after the weather clears, the
system might have malfuncti oned. Al-
though there is no problem to continue
driving, contact your Toyota dealer. If “E3” appears on the display,
a system
malfunction has been detected.
If this code appears, stop your vehicle in
a safe place, turn the ignition off, and
then restart it to reset the system. If the
setting still cannot be made or the same
code appears again, the system might
have malfunctioned. Although there is no
problem to continue driving, contact your
Toyota dealer. The conventional cruise control mode is
designed to maintain a set cruising
speed without requiring the driver to
operate the accelerator. Cruising speed
can be set to any speed above 45 km/h
(28 mph).
Within the limits of the engine’s capabili-
ties, cruising speed can be maintained up
or down grades. However, changes in ve-
hicle speed may occur on steeper grades.
CAUTION
In the conventional cruise control
mode, the approach warning does
not activate and no alarm will
sound even if you are too close to
the vehicle ahead, as neither the
presence of the vehicle ahead nor
the vehicletovehicle distance is
detected. Pay special attention to
the distance between your vehicle
and the vehicle ahead. Always con-
firm the setting in the display.

SETTING THE CRUISING SPEED
The transmission must be in “D” or “4”
before you set the cruising speed.
Bring your vehicle to the desired speed,
push the lever down in the “− SET” direc-
tion and release it. This sets the vehicle
at that speed and the display shows the
preset speed. You can now take your foot
off the accelerator pedal.
If you need to accelerate—for example,
when passing—depress the accelerator
pedal enough for the vehicle to exceed
the preset speed. When you release the
accelerator pedal, the vehicle will return to
the speed set prior to acceleration. You cannot set a desired speed if the
master warning light comes on, the alarm
sounds and the display indicates the
warning code “E3”. If this code appears
on the display, see “CONVENTIONAL
CRUISE CONTROL MODE FAILURE
WARNING” on page 239.
CANCELLING THE CONVENTIONAL
CRUISE CONTROL MODE
The conventional cruise control mode may
be temporarily cancelled by the driver or
by the system itself under certain circum-
stances. Temporary cancellation allows the
set cruising speed to remain in memory.
The conventional cruise control mode can
be temporarily cancelled by doing the fol-
lowing:
Pulling the lever in the “CANCEL” di-
rection and releasing it
Depressing the brake pedal
Under certain circumstances, the conven-
tional cruise control mode is temporarily
cancelled:
When vehicle speed falls below 40
km/h (25 mph)
When vehicle stability control is acti-
vated When vehicle speed drops 16 km/h (10
mph) below the set speed, the convention-
al cruise control mode is cancelled and
the set speed is erased from memory.
The “CRUISE” indicator light remains on
to indicate that the system is still in op-
eration.
To turn the system off, press the “ON
−
OFF” button. Make sure the “CRUISE” in-
dicator light is off.
If the conventional cruise control mode
automatically cancels out other than for
the above cases, have your vehicle
checked by your Toyota dealer at the ear-
liest opportunity.
RESUMING THE CONVENTIONAL
CRUISE CONTROL MODE
If the conventional cruise control mode is
temporarily cancelled, the cruising speed
can be resumed by pushing the lever up
in the “+ RES” direction.
Vehicle speed must be above 40 km/h (25
mph).

RESETTING TO A FASTER SPEED
Push the lever up in the “+ RES” direction
and hold it. Release the lever when the
desired speed is attained. While the lever
is held up, the vehicle will gradually gain
speed.
When the difference between the actual
vehicle speed and the set speed is less
than 5 km/h (3 mph), the set speed can
be increased 1.6 km/h (1 mph) each time
by pushing the lever up in the “+ RES”
direction quickly within 0.6 seconds.
However, a faster way to reset is to ac-
celerate the vehicle and then push the
lever down in the “− SET” direction.RESETTING TO A SLOWER SPEED
Push the lever down in the “
− SET” direc-
tion and hold it. Release the lever when
the desired speed is attained. While the
lever is held down, the vehicle speed will
gradually decrease.
When the difference between the actual
vehicle speed and the set speed is less
than 5 km/h (3 mph), the set speed can
be lowered 1.6 km/h (1 mph) each time
by pushing the lever down in the “ − SET”
direction quickly within 0.6 seconds.
However, a faster way to reset is to ac-
celerate the vehicle and then push the
lever down in the “− SET” direction.
Even if you downshift from “D” to “4” in
the conventional cruise control mode, en-
gine braking will not be enabled because
this mode is not cancelled. To decrease
the vehicle’s speed, reset to a slower
speed with the cruise control lever or de-
press the brake pedal. If you use the
brake pedal, cruise control is cancelled. CONVENTIONAL CRUISE CONTROL
MODE FAILURE WARNING
If there is trouble in the conventional
cruise control mode, the “CRUISE” indica-
tor light in the instrument cluster flashes,
the master warning light comes on and
the alarm sounds, the warning code “E3”
will appear on the display.
If a system malfunction is detected when
the conventional cruise control mode is in
the ready mode or operating, the master
warning light comes on, an alarm sounds
and the above code appears.
If this code appears, press the “ON
−OFF”
button to turn the system off and then
push it again to turn it on. If the setting
still cannot be made or the same code
appears again, the system might have
malfunctioned. Although there is no prob-
lem to continue driving, please contact
your Toyota dealer.

Long reach
type
Your engine is fitted with long reach
iridiumtipped spark plugs.
NOTICE
Use only Toyota genuine long reach
iridiumtipped spark plugs and do not
adjust gaps for your engine perfor-
mance and smooth driveability.
For details about the spark plug type, see
“Service specifications” on page 514 in
Section 8. 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 increase. 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
increase.
ANTILOCK BRAKE SYSTEM (with
“ABS” warning light)
The antilock brake system is designed
to help prevent lockup 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.

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 antilock
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.

Ty p e B
“ABS” warning light
Vehicles without the vehicle stability
control system—
The light comes on when the ignition key
is turned to the “ON” position. If the anti −
lock brake system works properly, the
light turns off after a few seconds. There-
after, if either of the systems malfunc-
tions, 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 does not operate,
but the brake system still operates con-
ventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti −lock brake system does not operate
but the brake assist system still operates.
In this case 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 components moni-
tored by the warning light system. Con-
tact 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 antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
Vehicles with the vehicle stability con-
trol system—
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 stability 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 components moni-
tored by the warning light system. Con-
tact 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 antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
DRUMINDISC TYPE PARKING BRAKE
SYSTEM (with rear disc brake)
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.
Have your Toyota dealer perform the bed-
ding− down.
