■Adjusting the set speed
To change the set speed, operate the lever until the desired set
speed is displayed.
Increases the speed
Decreases the speed
Fine adjustment: Momentarily
move the lever in the desired
direction.
Large adjustment: Hold the
lever in the desired direction.
In the vehicle-to-vehicle distance control mode, the set speed will be
increased or decreased as follows:
• When the set speed is shown in “MPH” Fine adjustment: By approximately 5 mph (8 km/h) each time the
lever is operated
Large adjustment: By approximately 5 mph (8 km/h) for each 0.75
seconds the lever is held
• When the set speed is shown in “km/h” Fine adjustment: By approximately 3.1 mph (5 km/h) each time the
lever is operated
Large adjustment: By approximately 3.1 mph (5 km/h) for each 0.75
seconds the lever is held
In the constant speed control mode ( P. 213), the set speed will be
increased or decreased as follows:
Fine adjustment: By approximately 1 mph (1.6 km/h) each time the
lever is operated.
Large adjustment: The set speed can be increased or decreased con-
tinually until the lever is released.

■Changing the vehicle -to-vehicle distance
Pressing the button changes
the vehicle-to-vehicle dis-
tance as follows:
Long
Medium
Short
The vehicle-to-vehicle distance
is set automatically to long
mode when the engine switch
is turned to the ON position.
If a vehicle is running ahead of
you, the preceding vehicle
mark will also be displayed.
■Canceling and resuming the speed control
Pulling the lever toward you
cancels the cruise control.
The speed setting is also can-
celed when the brakes are
applied.
Pushing the lever up
resumes the cruise control
and returns vehicle speed
to the set speed.
Resuming is available when
the vehicle speed is more than
approximately 25 mph (40
km/h).

When driving
Driving in vehicle-to-vehicle distance control mode
This mode employs a laser radar sensor to detect the presence of
vehicles up to approximately 400 ft. (120 m) ahead and to judge the
distance between your vehicle and those the vehicle ahead of you.
Note that vehicle-to-vehicle distance will close in when traveling on long
downhill slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-
vehicle distance can also be set by operating the vehicle-to-vehicle dis-
tance control.
Example of deceleration cruising
When the vehicle ahead is driving slower than the set speed
When a vehicle is detected running ahead of you, the system automati-
cally decelerates your vehicle. When a greater reduction in vehicle speed
is necessary, the system applies the brakes. A warning tone warns you
when the system cannot decelerate sufficiently to prevent your vehicle
from closing in on the vehicle ahead.

212 2-4. Using other driving systems
Example of follow-up cruising
When following a vehicle driving slower than the set speed
The system continues follow-up cruising while adjusting for changes in the
speed of the vehicle ahead in order to maintain the vehicle-to-vehicle dis-
tance set by the driver.
Example of acceleration
When there are no longer any vehi cles ahead driving slower than
the set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.
Approach warning
When your vehicle is too close to a vehicle ahead, and sufficient
automatic deceleration via the cruise control is not possible, the dis-
play will flash and the bu zzer will sound to alert the driver. An exam-
ple of this would be if another driver cuts in front of you while you are
following a vehicle. Apply the brakes to ensure an appropriate vehi-
cle-to-vehicle distance.

When driving
Selecting conventional cons tant speed control mode
Dynamic laser cruise control can be used as conventional cruise con-
trol if you select constant speed control mode.
Press the ON-OFF button to
activate the cruise control.
Press the button again to deacti-
vate the cruise control.
Vehicle-to-vehicle distance con-
trol mode is always reset when
the engine switch is turned to the
ON position.
Switch to constant speed con-
trol mode.
(Push the lever forward and
hold for approximately one
second.)
Constant speed control mode
indicator will come on.

214 2-4. Using other driving systems
■Dynamic laser cruise control can be set when
●The shift lever is in the D or range 4 or higher of S has been selected.
● Vehicle speed is above approximately 30 mph (50 km/h).
■ Switching modes
The mode cannot be switched to constant speed control mode if vehicle-to-
vehicle distance control mode has been used. The mode also cannot be
switched from constant speed control to vehicle-to-vehicle distance control
mode. Turn the system off by pressing the ON-OFF button, and turn it on
again.
■ Accelerating
The vehicle can accelerate normally. After acceleration, the set speed
resumes. However, during vehicle-to-vehicle distance control mode, the
vehicle speed may decrease below the set speed in order to maintain the
distance to the vehicle ahead.
■ Automatic cancelation of vehicle -to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the
following situations:
● Actual vehicle speed falls below approximately 25 mph (40 km/h)
● VSC is activated
● The sensor cannot operate correctly because it is covered in some way.
*
●The windshield wipers are operating at high or low speed.*
●The operation cannot be switched for 5 seconds or more after operating
the front wheel drive control switch or the center differential lock switch.
(4WD models)
*: Vehicle-to-vehicle distance control driving must be reset by pressing the
ON-OFF button again.
If vehicle-to-vehicle distance control dr iving is automatically canceled for any
other reason, there may be a malfunction in the system. Contact your Toyota
dealer.

When driving
■Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following sit-
uations:
●Actual vehicle speed is more than approximately 10 mph (16 km/h)
below the set vehicle speed
At this time, the memorized set speed is not retained.
● Vehicle speed falls below approximately 25 mph (40 km/h)
● VSC is activated
● The operation cannot be switched for 5 seconds or more after operating
the front wheel drive control switch or the center differential lock switch.
(4WD models)
■ Vehicle-to-vehicle distance settings
Select a distance from the table below. Note that the distances shown corre-
spond to a vehicle speed of 55 mph (90 km/h). Vehicle-to-vehicle distance
increases/decreases in accordance with vehicle speed.
■ Laser radar sensor
Distance optionsVehicle-to-vehicle distance
Long Approximately 245 ft. (75 m)
Medium Approximately 165 ft. (50 m) Short Approximately 100 ft. (30 m)
Always keep the sensor clean to ensure
that the vehicle-to-vehicle distance con-
trol operates properly. (Some obstruc-
tions, such as snow, ice and plastic
objects, cannot be detected by the
obstruction sensor.)
Dynamic laser cruise control is canceled
if an obstruction is detected.

216 2-4. Using other driving systems
■Warning lights, messages and buzzers for dynamic laser cruise control
Warning lights, messages and buzzers are used to indicate a system mal-
function or to inform the driver of the need for caution while driving.
(P. 613)
■ Approach warning
In the following instances, there is a possibility that the warnings will not
occur:
●When the speed of the vehicle ahead matches or exceeds your vehicle
speed
● When the vehicle ahead is traveling at an extremely slow speed
● Immediately after the cruise control speed was set
● At the instant the accelerator is applied
■ Certification
CAUTION
■Before using dynamic laser cruise control
Do not overly rely on vehicle-to-vehicle distance control.
Be aware of the set speed. If automatic deceleration/acceleration is not
appropriate, adjust the vehicle speed, as well as the distance between your
vehicle and vehicles ahead by applying the brakes etc.
■ Cautions regarding the driving assist systems
Observe the following precautions.
Failure to do so may cause an accident resulting in death or serious injury.
●Assisting the driver to measure following distance
The dynamic laser cruise control is only intended to help the driver in
determining the following distance between the driver’s own vehicle and a
designated vehicle traveling ahead. It is not a mechanism that allows care-
less or inattentive driving, and it is not a system that can assist the driver in
low-visibility conditions. It is still necessary for driver to pay close attention
to the vehicle’s surroundings.
