In vehicle-to-vehicle distance control mode, the vehicle automatically
accelerates and decelerates to match the speed changes of the pre-
ceding vehicle even if the accelerator pedal is not depressed. In con-
stant speed control mode, the vehicle runs at a fixed speed.

Use the dynamic radar cruise control on freeways and highways.

WARNING

■

Before using dynamic radar cruise control

●

Driving safely is the sole responsibility of the driver. Do not rely solely on

the system, and drive safely by always paying careful attention to your sur-

roundings.

●

The dynamic radar cruise control provides driving assistance to reduce the

driver's burden. However, there are limitations to the assistance provided.
Read the following conditions carefully. Do not overly rely on this system

and always drive carefully.
• When the sensor may not be correctly detecting the vehicle ahead:



P. 268

• Conditions under which the vehicle-to-vehicle distance control mode

may not function correctly:



P. 269

●

Set the speed appropriately depending on the speed limit, traffic flow, road

conditions, weather conditions, etc. The driver is responsible for checking

the set speed.

●

Even when the system is functioning normally, the condition of the preced-

ing vehicle as detected by the system may differ from the condition

observed by the driver. Therefore, the driver must always remain alert,

assess the danger of each situation and drive safely. Relying on this sys-

tem or assuming the system ensures safety while driving can lead to an

accident, resulting in death or serious injury.

●

Switch the dynamic radar cruise control off using the “ON-OFF” button

when not in use.

WARNING

■

Cautions regarding the driving assist systems

Observe the following precautions, as there are limitations to the assistance

provided by the system.

Failure to do so may cause an accident resulting in death or serious injury.

●

Assisting the driver to measure following distance

The dynamic radar 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.

●

Assisting the driver to judge proper following distance

The dynamic radar cruise control determines whether the following dis-

tance between the driver’s own vehicle and a designated vehicle traveling

ahead is within a set range. It is not capable of making any other type of

judgement. Therefore, it is absolutely necessary for the driver to remain

vigilant and to determine whether or not there is a possibility of danger in

any given situation.

●

Assisting the driver to operate the vehicle

The dynamic radar cruise control has limited capability to prevent or avoid

a collision with a vehicle traveling ahead. Therefore, if there is ever any

danger, the driver must take immediate and direct control of the vehicle

and act appropriately in order to ensure the safety of all involved.

WARNING

■

Situations unsuitable for dynamic radar cruise control

Do not use dynamic radar cruise control in any of the following situations.

Doing so may result in inappropriate speed control and could cause an acci-

dent resulting in death or serious injury.

●

Roads where there are pedestrians, cyclers, etc.

●

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 downhills, or where there are sudden changes between sharp up

and down gradients

Vehicle speed may exceed the set speed when driving down a steep hill.

●

At entrances to freeways and highways

●

When weather conditions are bad enough that they may prevent the sen-

sors from detecting correctly (fog, snow, sandstorm, heavy rain, etc.)

●

When there is rain, snow, etc. on the front surface of the radar sensor or

camera sensor

●

In traffic conditions that require frequent repeated acceleration and decel-

eration

●

When your vehicle is towing a trailer or during emergency towing

●

When an approach warning buzzer is heard often

Drivin

4RUNNER (U)

This mode employs a radar sensor to detect the presence of vehicles
up to approximately 320 ft. (100 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 switch.

Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears

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 (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.

Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed

The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.

the vehicle

: The area between the side of the vehicle and 1.6 ft. (0.5 m) from the

side of the vehicle cannot be detected.

Approximately 3.3 ft. (1 m) forward of the rear bumper
Approximately 9.8 ft. (3 m) from the rear bumper
Approximately 9.8 ft. (3 m) to 197 ft. (60 m) from the rear

bumper

: The greater the difference in speed between your vehicle and the

detected vehicle is, the farther away the vehicle will be detected, caus-

ing the outside rear view mirror indicator to illuminate or flash.

WARNING

■

Cautions regarding the use of the system

The driver is solely responsible for safe driving. Always drive safely, taking

care to observe your surroundings.
The Blind Spot Monitor is a supplementary function which alerts the driver

that a vehicle is in a blind spot of the outside rear view mirrors or is

approaching rapidly from behind into a blind spot. Do not overly rely on the

Blind Spot Monitor.
As the function cannot judge if it is safe to change lanes, over reliance could

lead to an accident resulting in death or serious injury. As the system may

not function correctly under certain conditions, the driver’s own visual confir-

mation of safety is necessary.

The following situations may occur during use.

• Depending on the shape of the obstacle and other factors, the detection

distance may shorten, or detection may be impossible.

• Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even

at slow speeds, there is a possibility that the obstacle will come within the
sensor’s detection areas before the display is shown and the warning
beep sounds.

• Thin posts or objects lower than the sensor may not be detected for colli-

sion when approached, even if they have been detected once.

• It might be difficult to hear beeps due to the volume of audio system or air

flow noise of air conditioning system.

ability of a sensor to correctly detect objects. Particular instances where this
may occur are listed below.

●

There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors
will resolve this problem.)

●

A sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the sensor display may be
displayed abnormally, or objects, such as a wall, may not be detected.

●

On an extremely bumpy road, on an incline, on gravel, or on grass.

●

When vehicle horns, vehicle detectors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of other vehicles or other devices which
produce ultrasonic waves are near the vehicle

●

A sensor is coated with a sheet of spray or heavy rain.

●

If objects draw too close to the sensor.

●

When a pedestrian is wearing clothing that does not reflect ultrasonic waves
(ex. skirts with gathers or frills).

●

When objects that are not perpendicular to the ground, not perpendicular to
the vehicle traveling direction, uneven, or waving are in the detection range.

●

Strong wind is blowing

●

When driving in inclement weather such as fog, snow or a sandstorm

●

When an object that cannot be detected is between the vehicle and a
detected object

●

If an object such as a vehicle, motorcycle, bicycle or pedestrian cuts in front
of the vehicle or runs out from the side of the vehicle

●

If the orientation of a sensor has been changed due to a collision or other
impact

●

When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an additional trim strip, etc.), bicycle carrier, or
snow plow

●

If the front of the vehicle is raised or lowered due to the carried load

●

If the vehicle cannot be driven in a stable manner, such as when the vehicle
has been in an accident or is malfunctioning

●

When a tire chains, compact spare tire or an emergency tire puncture repair
kit is used

●

When a sensor or the area around a
sensor is extremely hot or cold.

Situations in which the system may operate even if there is no possibil-
ity of a collision

In some situations, such as the following, the system may operate even
though there is no possibility of a collision.

●

When driving toward a banner, flag, low-hanging branch or boom barrier
(such as those used at railroad crossings, toll gates and parking lots)

●

When there is a rut or hole in the surface of the road

●

When driving on a metal cover (grating), such as those used for drainage
ditches

●

When driving up or down a steep slope

●

If a sensor is hit by a large amount of water, such as when driving on a
flooded road

●

There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors
will resolve this problem.)

●

A sensor is coated with a sheet of spray or heavy rain

●

When driving in inclement weather such as fog, snow or a sandstorm

●

When vehicle horns, vehicle detectors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of other vehicles or other devices which
produce ultrasonic waves are near the vehicle

●

If the front of the vehicle is raised or lowered due to the carried load

●

If the orientation of a sensor has been changed due to a collision or other
impact

●

The vehicle is approaching a tall or curved curb

●

Driving close to columns (H-shaped steel beams, etc.) in multi-story parking
garages, construction sites, etc.

●

If the vehicle cannot be driven in a stable manner, such as when the vehicle
has been in an accident or is malfunctioning

●

When driving on a narrow road

●

When strong winds are blowing

■

When the system malfunctions

●

If “Clean park sonar” is shown
A sensor may be dirty or covered with snow or ice. In such cases, if it is
removed from the sensor, the system should return to normal. Also, due to
the sensor being frozen at low temperatures, a malfunction display may
appear or an obstacle may not be detected. If the sensor thaws out, the sys-
tem should return to normal.

●

If “Check park sonar system” is shown
Depending on the malfunction of the sensor, the device may not be working
normally. Have the vehicle inspected by your Toyota dealer.

WARNING

■

Cautions regarding the use of the system

There is a limit to the degree of recognition accuracy and control perfor-

mance that this system can provide, do not overly rely on this system. The

driver is always responsible for paying attention to the vehicle’ surroundings

and driving safely.

■

To ensure the system can operate properly

Observe the following precautions.
Failing to do so may result in the vehicle being unable to be driven safely

and possibly cause an accident.

●

Do not damage the sensors, and always keep them clean.

●

Do not attach a sticker or install an electronic component, such as a backlit

license plate (especially fluorescent type), fog lights, fender pole or wire-

less antenna near a radar sensor.

●

Do not subject the surrounding area of the sensor to a strong impact. If

subjected to an impact, have the vehicle inspected by your Toyota dealer.

If the front or rear bumper needs to be removed/installed or replaced, con-

tact your Toyota dealer.

●

Do not modify, disassemble or paint the sensors.
