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 surroundings.

●

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. 265

• Conditions under which the vehicle-to-vehicle distance control mode may not

function correctly:



P. 266

●

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

tions, weather conditions, etc. The driver is responsible for checking the set speed.

●

Even when the system is functioning normally, the condition of the preceding 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 control off using the “ON/OFF” button 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 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 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 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 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.

GX460_OM_OM60R43U_(U)

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 accident result-

ing 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 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 sensors 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 sen-

sor

●

In traffic conditions that require frequent repeated acceleration and deceleration

●

When your vehicle is towing a trailer (with towing hitch) or during emergency towing

●

When an approach warning buzzer is heard often

258

GX460_OM_OM60R43U_(U)

This mode employs a radar sensor to detect the presence of vehicles up to
approximately 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 dis-

tance 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 deceler-

ates 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.

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 con-

stant speed cruising.

The sensor’s detection areas are limited to the areas around the vehicle’s bumper.

●

The following situations may occur during use.
• Depending on the shape of the object and other factors, the detection distance may

shorten, or detection may be impossible.

• Detection may be impossible if static objects draw too close to the sensor.

• There will be a short delay between object detection and display. Even at low

speeds, there is a possibility that the object will come within the sensor’s detection

areas before the display is shown and the warning beep sounds.

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

flow noise of the air conditioning system.

• It may be difficult to hear the sound of this system due to the buzzers of other sys-

tems.

■

Objects which the system may not properly detect

The shape of the obstacle may prevent a sensor from detecting it. Pay particular attention

to the following obstacles:

●

Wires, fences, ropes, etc.

●

Cotton, snow and other materials that absorb sound waves

●

Sharply-angled objects

●

Low obstacles

●

Tall obstacles with upper sections projecting outwards in the direction of your vehicle

■

Situations in which the system may not operate properly

Certain vehicle conditions and the surrounding environment may affect the 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 vehi-

cles, 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 vehi-

cle 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 vehi-

cle 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 tire chains, a compact spare tire or an emergency tire puncture repair kit are

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 possibility 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 vehi-

cles, 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.
