Driving
■Cruise control can be set when
●The shift lever is in D or the range 4, 5 or 6 of S has been selected.
● Vehicle speed is above approximately 25 mph (40 km/h).
■ Accelerating after setting the vehicle speed
●The vehicle can be accelerated normally. After acceleration, the set speed
resumes.
● Even without canceling the cruise control, the set speed can be increased
by first accelerating the vehicle to the desired speed and then pushing the
lever down to set the new speed.
■ Automatic cruise co ntrol cancelation
Cruise control will stop maintaining the vehicle speed in any of the following
situations.
● Actual vehicle speed falls more than approximately 10 mph (16 km/h) below
the preset vehicle speed.
At this time, the memorized set speed is not retained.
● Actual vehicle speed is below approximately 25 mph (40 km/h).
● VSC is activated.
■ Operation guide display (vehicles wi th a multi-information display [with
color display])
● When the cruise control switch is operated, a guidance display is shown on
the multi-information display for a few seconds as to how to operate the
cruise control switch. ( P. 98)
● When selecting tab on the multi-information display: P. 9 3
■ If the warning message for the crui se control is shown on the multi-
information display
Press the “ON-OFF” button once to deactivate the system, and then press
the button again to reactivate the system.
If the cruise control speed cannot be set or if the cruise control cancels imme-
diately after being activated, there may be a malfunction in the cruise control
system. Have the vehicle inspected by your Toyota dealer.

Doing so may result in loss of control and could cause an accident resulting
in death or serious injury.
●In heavy traffic
● On roads with sharp bends
● On winding roads
● On slippery roads, such as those covered with rain, ice or snow

Dynamic radar cruise control
Dynamic radar cruise control supple ments conventional cruise control
with a vehicle-to-vehicle distance control. In vehicle-to-vehicle dis-
tance control mode, the vehicle automatically accelerates or deceler-
ates in order to maintain a set fo llowing distance from vehicles ahead.

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 direc-
tion.
Large adjustment: Hold the lever in
the desired direction.
In the vehicle-to-vehicle distance co ntrol 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. 269), 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.

If a vehicle is running ahead of
you, the preceding vehicle mark
will be also displayed.
Select a distance from the table below. Note that the distances shown
correspond to a vehicle speed of 50 mph (80 km/h). Vehicle-to-vehicle
distance increases/decreases in accordance with vehicle speed.

Driving
Pulling the lever toward you
cancels the cruise control.
The speed setting is also canceled
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).
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 fr om 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.

4-5. Using the driving support systems
Example of deceleration cruising
When the vehicle ahead is drivi ng slower than the set speed
When a vehicle is detected running ahead of you, the system automatically
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 clos-
ing in on the vehicle ahead.
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.
When your vehicle is too close to a vehicle ahead, and sufficient auto-
matic deceleration via the cruise control is not possible, the display
will flash and the buzzer will sound to alert the driver. An example of
this would be if another driver cuts in front of you while you are follow-
ing a vehicle. Apply the brakes to ensure an appropriate vehicle-to-
vehicle distance.
■Warnings may not occur when
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 crui se control speed was set
● At the instant the accelerator is applied

Driving
Constant speed control mode differs from vehicle-to-vehicle distance
control mode. When cons tant speed control mode is selected, your
vehicle will maintain a set speed re gardless of whether or not there
are other vehicles in the lane ahead.
Press the “ON-OFF” button to
activate the cruise control.
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 sec-
ond)
Constant speed control mode indicator will be displayed.
When in constant speed control mode, to return to vehicle-to-vehicle dis-
tance control mode, push the leve r forward again and hold for approxi-
mately 1 second.
After the desired speed has been set, it is not possible to return to vehicle-
to-vehicle distance control mode.
If the engine switch is turned off and then turned to IGNITION ON mode
again, the vehicle will automatically return to vehicle-to-vehicle distance
control mode.

■Dynamic radar cruise control can be set when
●The shift lever is in the D or the range 4, 5 or 6 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 vehi-
cle speed may decrease below the set speed in order to maintain the dis-
tance to the vehicle ahead.
■ Automatic cancelation of vehic le-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the fol-
lowing 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 speed (when the wiper switch is
set to the “AUTO” mode or the high speed wiper operation position).
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 situ-
ations.
● 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.
■ Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-
vehicle distance control operates properly. (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.
