■Automatic cancelation of c onstant speed control mode
Constant speed control mode is automatically canceled in the following situa-
tions:
● Actual vehicle speed is more than approximately 10 mph (16 km/h ) below
the set vehicle speed.
● Actual vehicle speed falls below approximately 25 mph (40 km/h) .
● VSC is activated.
● TRAC is activated for a period of time.
● When the VSC or TRAC system is turned off.
● Pre-collision braking is activated.
If constant speed control mode is automatically canceled for an y other rea-
son, there may be a malfunction in the system. Contact your Toyota dealer.
■ Brake system operation sound
If the brakes are applied automatically while the vehicle is in vehicle-to-vehi-
cle distance control mode, a brake system operation sound may b e heard.
This does not indicate a malfunction.
■ Warning messages and buzzers for d ynamic radar cruise control
Warning messages and buzzers are used to indicate a system malfunction or
to inform the driver of the need for caution while driving. If a warning message
is shown on the multi-information display, read the message and follow the
instructions.
■ When the sensor may not be correctly detect ing the vehicle ahead
In the case of the following and depending on the conditions, o perate the
brake pedal when deceleration of the system is insufficient or operate the
accelerator pedal when acceleration is required.
As the sensor may not be able to correctly detect these types o f vehicles, the
approach warning ( P. 288) may not be activated.
● Vehicles that cut in suddenly
● Vehicles traveling at low speeds
● Vehicles that are not moving in the same lane

2924-5. Using the driving support systems
●Vehicles with small rear ends (trailers with no load on board, etc.)
● Motorcycles traveling in the same lane
● When water or snow thrown up by the surrounding vehicles hinders the
detecting of the sensor
●When your vehicle is pointing upwards
(caused by a heavy load in the luggage
compartment, etc.)
● Preceding vehicle has an extremely high
ground clearance

■Conditions under which the vehic le-to-vehicle distance control mode
may not function correctly
In the case of the following conditions, operate the brake peda l (or accelera-
tor pedal, depending on the situation) as necessary.
As the sensor may not be able to correctly detect vehicles ahead, the system
may not operate properly.
● When the vehicle ahead of you decelerates suddenly
● When driving on a road surrounded by a structure, such as in a tunnel or on
a bridge
● While the vehicle speed is decreasing to the set speed after th e vehicle
accelerates by depressing the accelerator pedal
●
When the road curves or when the lanes
are narrow
● When steering wheel operation or your
position in the lane is unstable

Cruise control
Use the cruise control to maintain a set speed without depressi ng the
accelerator pedal.
Indicators
Cruise control switch
Press the “ON-OFF” button to
activate the cruise control.
Cruise control indicator will come
on.
Press the button again to deacti-
vate the cruise control.
Accelerate or decelerate the
vehicle to the desired speed,
and push the lever down to set
the speed.
“SET” indicator will come on.
The vehicle speed at the moment
the lever is released becomes the
set speed.

To change the set speed, operate the lever until the desired set speed
is obtained.
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.
The set speed will be increased or decreased as follows:
Fine adjustment: By approximately 1 mph (1.6 km/h) each time th e lever is
operated.
Large adjustment: The set speed can be increased or decreased c ontinu-
ally until the lever is released.
Pulling the lever toward you
cancels the c onstant speed
control.
The speed setting is also canceled
when the brakes are applied.
Pushing the lever up resumes
the constant speed control.
Resuming is available when the
vehicle speed is more than approx-
imately 25 mph (40 km/h).

■Cruise control can be set when
●The shift lever is in D or range 4 or higher of S has been sele cted.
● Vehicle speed is above approximately 25 mph (40 km/h).
■ Accelerating after setting the vehicle speed
●The vehicle can be accelerated normally. After acceleration, th e 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 o f the following
situations.
● Actual vehicle speed falls more than approximately 10 mph (16 k m/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.
● TRAC is activated for a period of time.
● When the VSC or TRAC system is turned off.
● 4WD models: The operation cannot be switched for 5 seconds or m ore after
operating the front-wheel drive control switch.
■ If “Cruise Control Malfunction Vi sit Your Dealer” is displayed on the
multi-information display
Press the “ON-OFF” button once to deactivate the system, and th en press
the button again to reactivate the system.
If the cruise control speed cannot be set or if the cruise cont rol cancels imme-
diately after being activated, there may be a malfunction in th e cruise control
system. Have the vehicle inspected by your Toyota dealer.

WARNING
■To avoid operating the cruise control by mistake
Switch the cruise control off using the “ON-OFF” button when not in use.
■ Situations unsuitable for cruise control
Do not use cruise control in any of the following situations.
Doing so may result in loss of control and could cause an accid ent 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
● On steep hills
Vehicle speed may exceed the set speed when driving down a stee p hill.
● When your vehicle is towing a trailer or during emergency towin g

■Types of sensors
■Intuitive parking assist switch
Turns the intuitive parking
assist on/off
When on, the indicator light
comes on to inform the driver
that the system is operational.
: If equipped
The distance from your vehicle to nearby obstacles when paral-
lel parking or maneuvering into a garage is measured by the
sensors and communicated via t he multi-information display
and buzzer. Always check the surrounding area when using this
system.

■When multiple obstacles are de tected in front and behind the
vehicle at the same time
The buzzer will change in the following manner.
● If an obstacle has been detected within 1.5 ft. (45 cm) of the front
or 2.8 ft. (85 cm) in rear of t he vehicle (a continuous buzzer is
sounding), and a new obstacle is detected at the other end of the
vehicle, the buzzer w ill sound 7 times then 1 continuous buzzer.
● If an obstacle has been detected within 1.5 ft. (45 cm) of the front
or 2.8 ft. (85 cm) in rear of t he vehicle (a continuous buzzer is
sounding), and a new obstacle is detected in the same way at th e
other end of the vehicle, the buzzer will sound 3 times then 1
continuous buzzer.
■Detection range of the sensors
Approximately 5.9 ft. (180 cm)
Approximately 2.0 ft. (60 cm)
Approximately 2.8 ft. (85 cm)
The diagram shows the detection
range of the sensors. Note that the
sensors may not be able to detect
obstacles that are extremely close
to the vehicle.
The range of the sensors may
change depending on the shape of
the object, etc.
