Dynamic radar cruise controlwith full-speed

range

Summary of functions

In vehicle-to-vehicle distance control mode, the vehicle automatically

accelerates, decelerates and stops to match the speed changes of the

preceding vehicle even if the accelerator pedal is not depressed. In

constant speed control mode, the vehicle runs at a fixed speed.

Use the dynamic radar cruise control with full-speed range on free-

ways and highways.

WARNING

■ Before using dynamic radar cruise control with full-speed range

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 with full-speed range provides driving

assistance to reduce the driver’s burden. However, there are limitations to

the assistance provided.

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 system

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

dent, resulting in death or serious injury.

■ 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 with full-speed range 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 mecha-

nism that allows careless 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 with full-speed range determines

whether the following distance 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 neces-

sary 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 with full-speed range has limited capabil-

ity 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 con-

trol of the vehicle and act appropriately in order to ensure the safety of all

involved.

WARNING

■ To avoid inadvertent dynamic radar cruise control with full-speed

range activation

Switch the dynamic radar cruise control with full-speed range off using the

“ON-OFF” button when not in use.

■ Situations unsuitable for dynamic radar cruise control with full-speed

range

Do not use dynamic radar cruise control with full-speed range 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, cyclists, etc.

●In heavy traffic

●On roads with sharp bends

●On winding roads

4

●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 100 m (328 ft.) 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

1

When there are no vehicles ahead

The vehicle travels at the speed set by the driver. The desired vehi-

cle-to-vehicle distance can also be set by operating the vehicle-to-vehicle

distance switch.

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
