Dynamic radar cruise control

Summary of functions

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.

4

●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

4-5. Using the driving support systems

Driving in vehicle-to-vehicle distance control mode

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

1

2

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

3

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.

However, cruise control does not resume when the vehicle speed is

approximately 25 mph (40 km/h) or less.

Approach warning (vehicle-to-vehicle distance control mode)

When your vehicle is too close to

a vehicle ahead, and sufficient

automatic 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 following a vehicle.

Depress the brake pedal to

ensure an appropriate vehicle-to-

vehicle distance.

■ Warnings may not occur when

In the following instances, warnings may not occur even when the

vehicle-to-vehicle distance is small.

● When the speed of the preceding vehicle matches or exceeds

your vehicle speed

● When the preceding vehicle is traveling at an extremely slow

speed

● Immediately after the cruise control speed was set

● When depressing the accelerator pedal

4-5. Using the driving support systems

■Dynamic radar cruise control can be set when

●The shift lever is in D or range 3 or higher of S has been selected.

●Vehicle speed is at or above approximately 30 mph (50 km/h).

■Accelerating after setting the vehicle speed

The vehicle can accelerate by operating the accelerator pedal. After acceler-

ating, 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 preceding vehicle.

■Automatic cancelation of vehicle-to-vehicle distance control mode

Vehicle-to-vehicle distance control mode is automatically canceled in the fol-

lowing situations:

●Actual vehicle speed falls at or 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.

●The sensor cannot detect correctly because it is covered in some way.

●Pre-collision braking is activated.

4

If vehicle-to-vehicle distance control mode is automatically canceled for any

other reason, there may be a malfunction in the system. Contact your Toyota

dealer.

4-5. Using the driving support systems

■Automatic cancelation of constant 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 any 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 be heard.

This does not indicate a malfunction.

■Warning messages and buzzers for dynamic 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 detecting the vehicle ahead

In the case of the following and depending on the conditions, operate 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 of vehicles, the

approach warning (P. 265) may not be activated.

●Vehicles that cut in suddenly

●Vehicles traveling at low speeds

●Vehicles that are not moving in the same lane

●Vehicles with small rear ends (trailers with no load on board, etc.)

●Motorcycles traveling in the same lane

4RUNNER (U)

269

4-5. Using the driving support systems

●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 vehicle-to-vehicle distance control mode

may not function correctly

In the case of the following conditions, operate the brake pedal (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 road curves or when the

lanes are narrow

●When steering wheel operation or your

position in the lane is unstable

●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 the vehicle

accelerates by depressing the accelerator pedal
