■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 1 mph (1.6 km/h) each
time the lever is operated
Large adjustment: By approximat ely 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 0.6 mph (1 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. 307), the set speed will
be increased or decreased as follows:
Fine adjustment: By approximat ely 1 mph (1.6 km/h) each time
the lever is operated
Large adjustment: The set speed can be increased or
decreased continually 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
Vehicles without a smart key
system:
The vehicle-to-vehicle distance
is set automatically to long
mode when the engine switch
is turned to the “ON” position.
Vehicles with a smart key sys-
tem:
The vehicle-to-vehicle distance
is set automatically to long
mode when the “ENGINE
START STOP” switch is turned
to IGNITION ON mode.
If a vehicle is running ahead of
you, the preceding vehicle
mark will be also displayed.

■Vehicle-to-vehicle distance settings
Select a distance from the table below. Note that the distances
shown correspond to a vehicle speed of 50 mph (80 km/h). Vehi-
cle-to-vehicle distance increases/decreases in accordance with
vehicle speed.
■ Canceling and resuming the speed control
Pulling the lever toward you
cancels the constant speed
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).
Distance optionsVehicle-to-vehicle distance
LongApproximately 160 ft. (50 m)
MediumApproximately 130 ft. (40 m)
ShortApproximately 100 ft. (30 m)

Driving in vehicle-to-vehicle distance control mode
This mode employs a radar sensor to detect the presence of vehicles
up to approximately 400 ft. (120 m) ahead, determines the current
vehicle-to-vehicle following distance, and operates to maintain a suit-
able following distance from the vehicle ahead.
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.

306 2-4. Using other driving systems
SIENNA_OM_OM45472U_(U)Example of follow-up cruising
When following a vehicle driv
ing 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.
■ Warnings may not occur when
In the following instan ces, there is a possibility that the warnings
will not occur:
● When the speed of the vehicl e 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

Selecting conventional cons tant speed control mode
Constant speed control mode differ s from vehicle-to-vehicle distance
control mode. When constant spee d control mode is selected, your
vehicle will maintain a set speed regardless of whether or not there
are other vehicles in the lane ahead.
Press the “ON-OFF” button to
activate the cruise control.
Dynamic radar cruise control indi-
cator will come on.
Press the button again to deacti-
vate the cruise control.
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.
When in constant speed control
mode, to return to vehicle-to-vehi-
cle distance control mode, push
the lever forward again and hold
for approximately 1 second.
After the desired speed has been
set, it is not possible to return to
vehicle-to-vehicle distance con-
trol mode.

Vehicles without a smart key sys-
tem:
If the engine switch is turned off
and then turned to the “ON” posi-
tion again, the vehicle will auto-
matically return to vehicle-to-
vehicle distance control mode.
Vehicles with a smart key system:
If the “ENGINE START STOP”
switch is turned off and then
turned to IGNITION ON mode
again, the vehicle will automati-
cally return to vehicle-to-vehicle
distance control mode.

■Dynamic radar cruise control can be set when
● The shift lever is in the D or more than range 4 of S has been selected.
● Vehicle speed is above approximately 30 mph (50 km/h).
■ Accelerating after setting the vehicle speed
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).
● Enhanced VSC is activated.
● The sensor cannot operate correctly because it is covered in some way.
● The windshield wipers are operating at high speed (when the wiper
switch is set to the “AUTO” mode or the high speed wiper operation posi-
tion).
If vehicle-to-vehicle distance control driving is automatically canceled for any
other reason, there may be a malfunction in the system. Contact your Toyota
dealer.

■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 appr oximately 25 mph (40 km/h).
● Enhanced VSC is activated.
■ Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle\
-to-
vehicle distance control operates pr operly. (Some obstructions, such as
snow, ice and plastic objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control is canceled if an obstruction is detected.
■ Warning lights for dynamic radar cruise control
Warning light is used to indicate a system malfunction or to inform the driver
of the need for caution while driving. ( P. 745)
