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.

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.
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.

When the engine switch 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 engine switch 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 236.
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

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.CHANGING VEHICLETOVEHICLE
DISTANCE
You can select one of the following ve-
hicle− to−vehicle distances.
1. LONG
2. MIDDLE
3. SHORT
Each time you pull the distance switch
briefly toward you, the setting changes
from LONG to MIDDLE to SHORT and
then back to LONG. You can confirm the
setting on the display.
Your vehicle speed changes in proportion
to the speed of the vehicle ahead, main-
taining the selected distance. However, if
the vehicle ahead is slower, the selected
distance will be shorter than the desig-
nated distance.
When the vehicle −to −vehicle distance con-
trol mode is activated or the “READY”
indicator comes on, the vehicle −to −vehicle
distance setting can be changed.
The vehicle −to −vehicle distance is always
set to LONG when the engine switch is
turned on.

Select the vehicle−to −vehicle distance con-
sidering traffic conditions. The approximate
vehicle −to −vehicle distance based on time
interval when driving at 88 km/h (55 mph)
is shown below:
LONG about 75 m (245 ft.)
. . . . . . . . . . .
MIDDLE about 50 m (165 ft.)
. . . . . . . . . .
SHORT about 30 m (100 ft.)
. . . . . . . . . .
If the vehicle speed is slower than 88
km/h (55 mph), the distance will be short-
er than the above.
During long downhill driving, the vehicle −
to −vehicle distance will be shorter than
the selected distance.
BRAKING CONTROL
Dynamic laser cruise control is not a colli-
sion avoidance system. If the approach
warning is activated, depress the brake
pedal to decelerate to ensure an appropri-
ate vehicle− to−vehicle distance.
If you are getting closer to the vehicle
ahead at a relatively higher speed than
that of the vehicle ahead or if engine
braking cannot be applied properly, brak-
ing control is automatically activated. Braking control is operating only when the
vehicle−
to−vehicle distance control mode
is selected and your vehicle speed ex-
ceeds about 40 km/h (25 mph). If the
speed decreases below about 40 km/h (25
mph), braking control will cease, requiring
the manual application of brakes.
CAUTION
Braking control will not ensure that
your vehicle will reduce speed ap-
propriately. You must depress the
brake pedal to slow down, ensuring
collision avoidance or that sufficient
vehicletovehicle distance is main-
tained.
APPROACH WARNING
While you are cruising in the vehicle −to −
vehicle distance control mode, if the ve-
hicle ahead decelerates abruptly or if
another vehicle cuts in ahead of you, in-
adequate braking will make your vehicle
become closer to the vehicle ahead of you
and the display will flash and beep.

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 engine switch 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.
Do not use the conventional mode
in the following conditions, or seri-
ous 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.
Be careful about vehicle speed as
it may increase when driving down-
hill with the conventional cruise
control mode selected.
