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 pay-

ing careful attention to your surround-

ings.

●

The dynamic radar cruise control with

full-speed range provides driving

assistance to reduce the driver’s bur-

den. However, there are limitations to

the assistance provided.

Read the following conditions care-

fully. Do not overly rely on this system

and always drive carefully.

• When the sensor may not be correctly

detecting the vehicle ahead:



P.197

• Conditions under which the vehicle-

to-vehicle distance control mode may

not function correctly:



P.197

●

Set the speed appropriately depend-

ing on the speed limit, traffic flow, road

conditions, weather conditions, etc.

The driver is responsible for checking

the set speed.

WARNING

●

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 accident,

resulting in death or serious injury.

●

Switch the dynamic radar cruise con-

trol with full-speed range off using the

cruise control main switch when not in

use.

■

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 follow-

ing distance

The dynamic radar cruise control with

full-speed range is only intended to

help the driver in determining the fol-

lowing distance between the driver’s

own vehicle and a designated vehicle

traveling ahead. It is not a mechanism

that allows careless or inattentive driv-

ing, 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 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 with

full-speed range 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 con-

trol of the vehicle and act appropri-

ately in order to ensure the safety of all

involved.

■

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 follow-

ing 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

●

On slippery roads, such as those cov-

ered 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 high-

ways

●

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

front camera

●

In traffic conditions that require fre-

quent repeated acceleration and

deceleration

191

4-5. Using the driving support systems

Driving

This mode employs a radar sensor to detect the presence of vehicles up to approx-
imately 328 ft. (100 m) ahead, determines the current vehicle-to-vehicle following
distance, and operates to maintain a suitable 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 distance 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 sufficiently to
prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is stopped by sys-
tem control). After the vehicle ahead starts off, pressing the “+RES” switch or depressing
the accelerator pedal will resume follow-up cruising.
