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
To operate dynamic laser cruise control,
press the “ON−OFF” button. This turns the
system on. When the “CRUISE” and
“READY” indicator lights in the instrument
cluster come on, you can now set your
desired cruising speed and vehicle −to −ve-
hicle distance. Pressing the “ON −OFF”
button again will turn the system com-
pletely off.
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, keep the “ONOFF”
button off when not using the dynam-
ic laser cruise control.
SETTING THE DESIRED SPEED
The transmission must be in “D” before
you set the cruise control 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 214.
CANCELLING THE PRESET SPEED
You can cancel the preset speed by doing
any of the following:
a. Pulling the lever in the “CANCEL” direction.
b. Depressing the brake pedal. c. Pressing the “ON −OFF” button.
If cancelled by a. or b., the “READY”
indicator comes on and the dynamic laser
cruise control enters the ready mode.
If cancelled by c., the “CRUISE” indicator
light goes off in the instrument panel. In
this case, the preset speed data is
cleared, and you must set the speed from
the beginning. In the following cases, the preset speed
automatically cancels out:
a. The vehicle speed falls below about 40 km/h (25 mph). (40 km/h (25 mph) is
designated as a cancel speed.)
b. The slip indicator light blinks and an alarm sounds. (This occurs when the
vehicle is about to skid.)
If cancelled by a. or b., the “READY”
indicator comes on and the dynamic laser
cruise control enters the ready mode.
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 214.
If the preset speed automatically cancels
out for other than the above reasons, do
not operate the dynamic laser cruise con-
trol. Although there is no problem to con-
tinue driving, please contact your Toyota
dealer. 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.

2005 SIENNA from Sep. ’04 Prod. (OM45431U)
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. RESUMING THE PRESET SPEED
If the preset speed has been cancelled,
when you push the lever up in the
“+ RES” direction while the “READY” indi-
cator in the instrument cluster comes on
at a vehicle speed of more than 40 km/h
(25 mph), the speed set prior to cancella-
tion will be restored.
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.

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, please 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, please con-
tact your Toyota dealer. This mode allows you to cruise at a
desired speed over about 45 km/h (28
mph) with your foot off the accelerator
pedal.
Your cruising speed can be maintained up
or down grades within the limits of engine
performance, although a slight speed
change may occur when driving up or
down the grades. On steeper hills, a
greater speed change will occur so it is
better to drive without the cruise control.
CAUTION
In the conventional (fixed speed)
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 confirm the setting in the
display.

Do not use the conventional (fixed
speed) mode in the following condi-
tions, or serious injury or death
could result:
To help maintain maximum control
of your vehicle, do not use conven-
tional cruise control mode when us-
ing dynamic laser cruise control
while driving in heavy or varying
traffic, or on slippery (rainy, icy or
snowcovered) or winding roads.
Avoid vehicle speed increasing
when driving downhill. If the vehicle
speed is too fast in relation to the
preset speed in the conventional
cruise control mode, cancel the
conventional cruise control mode
and then downshift the transmis-
sion to use engine braking to slow
down.
TURNING THE SYSTEM ON
To operate conventional cruise control
mode, press the “ON−OFF” button. This
turns the system on. The “CRUISE” and
“READY” indicator lights in the instrument
cluster comes on. Push the lever in the
“MODE” direction for longer than 1 second
to change to conventional cruise control
mode. The indicator in the instrument
cluster is as shown. You can now set
your desired cruising speed. Pressing the
“ON −OFF” button again will turn the sys-
tem completely off. However, once the vehicle
−to −vehicle dis-
tance control mode activates and is used,
it cannot be changed to the conventional
cruise control mode using the above op-
eration. To change the mode, press the
“ON −OFF” button to turn the system off
and then press it again to turn it on. Next
push the lever in the “MODE” direction for
longer than about 1 second.
To change to the vehicle− to−vehicle dis-
tance control mode from the conventional
cruise control mode, push the lever in the
“MODE” direction for longer than about 1
second.
CAUTION
To avoid accidentally engaging cruise
control, keep the “ONOFF” button
off when not using dynamic laser
cruise control.

SETTING THE DESIRED SPEED
The transmission must be in “D” before
you set the cruise control speed in the
conventional cruise control mode.
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 218.
CANCELLING THE PRESET SPEED
You can cancel the preset speed by doing
any of the following:
a. Pulling the lever in the “CANCEL” direction.
b. Depressing the brake pedal. c. Pressing the “ON −OFF” button.
In the following cases, the preset speed
automatically cancels out: a. The vehicle speed falls below about 40km/h (25 mph).
b. If the vehicle speed drops 16 km/h (10 mph) below the preset speed, the pre-
set speed will also automatically be
cancelled.
c. The slip indicator light blinks and an alarm sounds. (This occurs when the
vehicle is about to skid.)
If cancelled by b., the preset speed data
is cleared and you must set the speed
from the beginning. If the preset speed automatically cancels
out for other than the above reasons, do
not operate the cruise control. Although it
is no problem to continue driving, have
your vehicle checked by your Toyota deal-
er at the earliest opportunity.
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.
