RSA (Road Sign Assist)

RSA recognizes specific road signs
using the camera sensor and pro-
vides information to the driver via
the multi-information display.

If the system judges that the vehicle
is being driven over the speed limit,
performing prohibited actions, etc.
in relation to the recognized road
signs, it alerts the driver using a
warning display and warning
buzzer

: This setting needs to be customized.

WARNING

■

Before using the RSA

Do not rely solely upon the RSA system.

RSA is a system which supports the

driver by providing information, but it is

not a replacement for a driver’s own

vision and awareness. Drive safely by

always paying careful attention to the

traffic rules.
Inappropriate or negligent driving could

lead to an unexpected accident.

176

4-5. Using the driving support systems

After the camera sensor recognizes a
sign, it is displayed on the multi-infor-
mation display when the vehicle passes
the sign.

■

Conditions in which the function may

not operate or detect correctly

In the following situations, RSA does not

operate normally and may not recognize

signs, display the incorrect sign, etc. How-

ever, this does not indicate a malfunction.

●

The camera sensor is misaligned due to a

strong impact being applied to the sen-

sor, etc.

●

Dirt, snow, stickers, etc. are on the wind-

shield near the camera sensor.

●

In inclement weather such as heavy rain,

fog, snow or sand storms

●

Light from an oncoming vehicle, the sun,

etc. enters the camera sensor.

●

The sign is dirty, faded, tilted or bent, and

if an electronic sign, the contrast is poor.

●

All or part of the sign is hidden by the

leaves of a tree, a pole, etc.

●

The sign is only visible to the camera sen-

sor for a short amount of time.

●

The driving scene (turning, lane change,

etc.) is judged incorrectly.

●

Even if it is a sign not appropriate for the

currently traveled lane, such a sign exists

directly after a freeway branches, or in an

adjacent lane just before merging.

●

Stickers are attached to the rear of the

preceding vehicle.

●

A sign resembling a system compatible

sign is recognized.

●

The vehicle is driven in a country with a

different direction of traffic.

●

Side road speed signs may be detected

and displayed (if positioned in sight of the

camera sensor) while the vehicle is

traveling on the main road.

●

Roundabout exit road speed signs may

be detected and displayed (if positioned

in sight of the camera sensor) while

traveling on a roundabout.

■

When driving vehicle in country with dif-

ferent speed unit

Since RSA recognizes signs based on the

set unit of the meter, it is necessary to

change the set unit of the meter. Adjust the

set unit of the meter to the speed unit of

signs in the current location. (

WARNING

■

Before using dynamic radar cruise

control

Driving safely is the sole responsibility of

the driver. Do not rely solely on the sys-

tem, and drive safely by always paying

careful attention to your surroundings.

The dynamic radar cruise control pro-

vides driving assistance to reduce the

driver’s burden. However, there are limi-

tations to the assistance provided.

Set the speed appropriately depending

on the speed limit, traffic flow, road con-

ditions, weather conditions, etc. The

driver is responsible for checking the set

speed.

Even when the system is functioning nor-

mally, 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 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.

180

4-5. Using the driving support systems

WARNING

●

Assisting the driver to measure follow-

ing distance

The dynamic radar cruise control is only

intended to help the driver in determin-

ing 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 condi-

tions. 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 deter-

mines 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 deter-

mine 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 appropri-

ately in order to ensure the safety of all

involved.

■

To avoid inadvertent dynamic radar

cruise control activation

●

Switch the dynamic radar cruise con-

trol off using the “ON/OFF” button

when not in use.

■

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,

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 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 fre-

quent repeated acceleration and

deceleration

●

During emergency towing

●

When an approach warning buzzer is

heard often

181

4-5. Using the driving support systems

Driving

This mode employs a radar sensor to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) 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 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.

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.
