If you need acceleration—for example,
when passing—depress the accelerator
pedal enough for the vehicle to exceed
the set speed. When you release it, the
vehicle will return to the speed set prior
to the acceleration.
CANCELLING THE CRUISE CONTROL
The cruise control may be temporarily
cancelled by the driver or by the system
itself under certain circumstances. Tempo-
rary cancellation allows the set cruising
speed to remain in memory.
The cruise control can be temporarily can-
celled by doing the following:
Pulling the lever in the “CANCEL” di-
rection and releasing it
Depressing the brake pedal
Under certain circumstances, the cruise
control 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 cruise con-
trol 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 cruise control off, press the
“ON
−OFF” button. Make sure the
“CRUISE” indicator light is off.
If the cruise control automatically cancels
out other than for the above cases, have
your vehicle checked by your Toyota deal-
er at the earliest opportunity.
RESUMING THE CRUISE CONTROL
If the cruise control is temporarily can-
celled, 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.
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.
However, a faster way to reset is to de-
press the brake pedal and then push the
lever down in the “− SET” direction.
Even if you downshift from “D” to “4”, with
the cruise control on, engine braking will
not be enabled because the cruise control
is not cancelled. To decrease the vehicle
speed, reset to a slower speed with the
cruise control lever or depress the brake
pedal. If you use the brake pedal, cruise
control is cancelled.

CRUISE CONTROL FAILURE WARNING
If the “CRUISE” indicator light flashes
when using the cruise control, press the
“ON−OFF” button to turn the system off
and then press it again to turn it on.
If any of the following conditions then oc-
curs, there is some trouble in the cruise
control system.
The indicator light does not come on.
The indicator light flashes again.
The indicator light goes out after it
comes on.
If this is the case, contact your Toyota
dealer and have your vehicle inspected. Dynamic laser cruise control allows you
to drive at a selected cruising speed
over about 45 km/h (28 mph) with your
foot off the accelerator pedal, maintain-
ing an appropriate vehicletovehicle
distance.
CAUTION
Do not rely excessively on dynamic
laser cruise control in order to avoid
serious injury or death, or to prevent
accidents or to control the vehicle’s
speed in emergency situations. Do
not use cruise control except in ap-
propriate road and traffic conditions.
Always drive carefully and attentively.
Before using dynamic laser cruise
control, read and understand the fol-
lowing instructions.

Conventional (fixed speed) cruise con-
trol mode for cruising at preset speeds
You can change the mode by using the
control lever.
The two cruise control modes function dif-
ferently. If you use dynamic laser cruise
control, always confirm which mode is se-
lected.
For the vehicle −to −vehicle distance control
mode, see “—Vehicle −to −vehicle distance

The system’s laser radar sensor detects
the reflectors of vehicles and measures
the vehicletovehicle distance. The
detection range of the sensor is about
120 m (400 ft.) ahead.
CAUTION
Dynamic laser cruise control is not a
collisionavoidance system and will
not prevent accidents. Dynamic laser
cruise control is a vehicle speed con-
trol device that is intended for use
only on freeways or roads where the
traffic is light or moderate. To avoid
serious injury, you must use caution
and be attentive to road and traffic
conditions while using dynamic laser
cruise control.
DYNAMIC LASER CRUISE CONTROL
OPERATIONS
The dynamic laser cruise control func-
tion operates automatically and depend-
ing on whether a vehicle is detected
ahead may change the speed of your
vehicle as follows.
If no vehicle is running ahead of you—1. Cruising at a fixed speed: If there is
no vehicle detected ahead, your
cruising speed is maintained at the
preset speed from about 45 km/h (28
mph) to about 135 km/h (85 mph). The
preset speed is displayed in the
display. For the vehicle speed setting,
see “SETTING THE CRUISING SPEED”
on page 230.

2007 SIENNA from Oct. ’06 Prod. (OM45437U)
If a vehicle is detected ahead of you—2. Deceleration cruising function: If a
slower moving vehicle is detected
ahead of you, your vehicle cruising
speed decreases within the range of
about 40 km/h (25 mph) to about 135
km/h (85 mph). The display shows the
preset speed, the detected vehicle
ahead and selected vehicle −to −vehicle
distance. If your vehicle gets closer to
the vehicle ahead because of insuffi-
cient automatic deceleration, then the
alarm warns you to also manually ap-
ply brakes.
3. Followup cruising function: After de-
celeration, your vehicle cruising speed
changes in proportion to the speed of
the vehicle ahead to maintain an ap-
propriate distance from your vehicle to
the vehicle ahead. The vehicle −to −ve-
hicle distance can be changed. For de-
tails, see “CHANGING VEHICLE −TO −
VEHICLE DISTANCE” on page 233.
4. Acceleration cruising function: If the
vehicle ahead changes lanes, your ve-
hicle cruising speed will be gradually
increased up to the preset speed, and
your vehicle resumes fixed −speed
cruising. This system operates by detecting pri-
marily the reflectors of the vehicle
ahead. The distance may not be accu-
rately or absolutely detected in the fol-
lowing cases:
The vehicle ahead has higher ground
clearance, which means that the
placement of the reflectors is in a
higher position.
The rear section of the vehicle ahead
is extremely dirty.
The vehicle ahead or other vehicles
around you are flinging up water or
snow.
Excessive exhaust gas (black smoke)
is coming from the vehicle ahead or
other vehicles around you, obscuring
your front view.
There is an obstruction (protective
film, sticker, etc.) on the reflectors
on the vehicle ahead, or reflectors
are not installed on the vehicle
ahead or are damaged.
Heavy luggage in the luggage
compartment or rear seats is caus-
ing the nose of your vehicle to tilt
up.
CAUTION
To avoid accidents, always keep the
laser radar sensor glass clean and
never allow it to be covered with
icicle or any substance, so it can de-
tect the vehicle in front. (See “LASER
RADAR SENSOR” on page 234.)

CAUTION
Do not rely excessively on dynamic
laser cruise control. Observe the fol-
lowing precautions in order to avoid
serious injury or death:
Under certain conditions where the
vehicle in front slows drastically, or
is stopped, the dynamic laser cruise
control will neither warn you nor
decelerate. You must depress the
brake pedal to slow down, ensuring
collision avoidance or that suffi-
cient vehicletovehicle distance is
maintained.
Do not use dynamic laser cruise
control in the following conditions:
In bad weather (such as rain, fog,
snow, sandstorms or direct sun-
light, or when raindrops or snow-
flakes get on the laser radar sensor
glass), the vehicletovehicle dis-
tance will not be measured accura-
tely.
When using the windshield wipers
at high or low speeds the dynamic
laser radar cruise control turns off.
On roads with heavy traffic or
sharp bends, an appropriate speed
cannot be maintained and an acci-
dent may occur.
On slippery road surfaces (icy or
snowcovered road surfaces), the
tires will race and you will be un-
able to control the vehicle.
When there is no vehicle detected
ahead on steep downhill slopes, the
preset speed will be easily exceed-
ed because of inefficient engine
braking. (In this case, automatic
braking will not work.) If there is a
vehicle detected ahead, the delay in
deceleration timing could cause se-
rious injury or death.
When the alarm sounds frequently
(because acceleration or decelera-
tion was repeated or sufficient ve-
hicletovehicle distance was not
maintained), an appropriate vehicle
speed cannot be attained and an
accident may occur.On roads with steep and short in-
clines and declines, failure to de-
tect the vehicle ahead will shorten
the distance between your vehicle
and the vehicle ahead and an acci-
dent may occur.
Deceleration cruising function and
approach warning do not operate
when the vehicle ahead is at a stop
or driving very slowly.
If the vehicle ahead of you deceler-
ates abruptly or if another vehicle
cuts in ahead of you, your vehicle
may collide with the vehicle ahead
unless you manually depress the
brake pedal to slow down your ve-
hicle.

2007 SIENNA from Oct. ’06 Prod. (OM45437U)
Depending on the road configura-
tion (curved, left and right continu-
ous curved, the start or end of a
curve, or narrow driving lanes due
to road construction) or your ve-
hicle condition (steering wheel ma-
neuvering, position in the lane, or
unstable driving because of an acci-
dent or breakdown), vehicles in oth-
er lanes or surrounding objects
may be detected, resulting in a con-
trol failure or the approach warning
activation. This may also result in
a very close distance between vehi-
cles due to a failure to detect the
vehicle ahead.
Dynamic laser cruise control should not
be used in circumstances which are inap-
propriate for any cruise control, such as
entering free way on−ramps or off −ramps.
CAUTION
Do not use dynamic laser cruise
control when exiting from or when
entering or merging onto a freeway.
When you are following a slower
moving vehicle and exiting, the sen-
sor does not detect the vehicle and
will accelerate to the preset speed.
If other vehicles are driving outside
of the laser radar detection range,
a delay in the detection of the ve-
hicle cutting in at short range or
failure to detect a motorcycle run-
ning on the side of the same lane
will occur. In this case, the dynamic
laser cruise control system will not
function properly.
When a slower vehicle in front of
you leaves the lane, the dynamic
laser cruise control will no longer
detect a vehicle ahead and will at-
tempt to accelerate the vehicle to
the faster preset speed.

TURNING THE SYSTEM ON AND OFF
To turn the dynamic laser cruise control
on, turn the “ON−OFF” button on. The
“CRUISE” and “READY” indicator lights on
the instrument panel will come on to indi-
cate that the vehicle− to−vehicle distance
control mode is operational. Pressing the
“ON −OFF” button again turns the system
off.
When the system is turned off, cruising
speed and vehicle −to −vehicle distance
must be reset when the vehicle −to −vehicle
distance control mode is turned on again.
When the ignition is turned off, the system
is also automatically turned off. To use
dynamic laser cruise control again, press
the “ON −OFF” button again to turn it on. When the ignition is turned off, all the
preset data is cleared. When you use the
dynamic laser cruise control again, you
need to reset the data.
CAUTION
To avoid accidentally engaging the
cruise control, turn the system off
when it is not in use. Make sure the
“CRUISE” indicator light is off.
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. At this time, the display
indicates settings such as the preset ve-
hicle speed, whether a vehicle is present
ahead and selected vehicle −to −vehicle dis-
tance. If there is no vehicle detected
ahead, the display does not indicate the
vehicle ahead. 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 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.

07 SIENNA_U (L/O 0612)

2007 SIENNA from Oct. ’06 Prod. (OM45437U)
RESETTING TO A FASTER SPEED
Push the lever up in the “+ RES” direction
and hold it. The displayed speed will in-
crease in increments of 5 mph (for the
U.S.A.) or 5 km/h (for Canada). Release
the lever when the desired speed is attai-
ned. The vehicle speed will gradually in-
crease to the display speed.
However, a faster way to reset is to ac-
celerate the vehicle and then push the
lever down in the “− SET” direction.
CAUTION
When the vehicletovehicle distance
control is on, your cruising speed is
regulated in proportion to the speed
of the vehicle ahead, so increasing
the preset speed using the control
lever does not accelerate the vehicle.
However, if the vehicle ahead leaves
the lane, your cruising speed will in-
crease to the preset speed because
the preset speed has been set higher
using the control lever. Confirm the
setting on the display.
RESETTING TO A SLOWER SPEED
Push the lever down in the “− SET” direc-
tion and hold it. The displayed speed will
decrease in increments of 5 mph (for the
U.S.A.) or 5 km/h (for Canada). Release
the lever when the desired speed is attai-
ned. The vehicle speed will gradually de-
crease to the display speed.
However, a faster way to reset is to de-
press the brake pedal and then push the
lever down in the “− SET” direction.
If the control lever is released when the
vehicle speed exceeds the upper limit of
the preset speed traveling downhill while
you are pushing the lever down, the sys-
tem will memorize the upper limit of the
preset speed as a preset speed.
Even if you downshift from “D” to “4” in
the vehicle− to−vehicle distance control
mode, engine braking will not be enabled
because this mode is not cancelled. To
decrease the vehicle speed, reset to a
slower speed with the cruise control lever
or depress the brake pedal. If you use the
brake pedal, cruise control is cancelled.
