RSA (Road Sign Assist)

*

The RSA system recognizes spe-
cific road signs using the front cam-
era and/or navigation system (when 
speed limit information is available) 
to provide information to the driver 
via the display.

If the system judges that the vehicle 
is being driven over the speed limit, 
performing prohibited actions, etc. 
according to the recognized road 
signs, it notifies the driver through a 
visual notification and notification 
buzzer or steering wheel vibration.

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.

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 

surroundings.

●

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.252

• Conditions under which the vehi-

cle-to-vehicle distance control mode 

may not function correctly: 



P.253

●

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.

●

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 solely 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 setting to 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 follow-

ing 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 vehi-

cle 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 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 vigi-

lant 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 does not include func-

tions which will prevent or avoid colli-

sions with vehicles ahead of your vehicle. 

Therefore, if there is ever any possibility 

of danger, the driver must take immedi-

ate and direct control of the vehicle and 

act appropriately 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 accident 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 or front cam-

era

●

In traffic conditions that require fre-

quent repeated acceleration and 

deceleration

●

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

This mode employs a radar to detect the presence of vehicles up to approximately 
100 m (328 ft.) ahead, determines the current vehicle-to-vehicle following dis-
tance, and operates to maintain a suitable following distance from the vehicle 
ahead. The desired vehicle-to-vehicle distance can also be set by operating the 
vehicle-to-vehicle distance switch.

When driving on downhill slopes, the vehicle-to-vehicle distance may become shorter.

Example of constant speed cruising
When there are no vehicles ahead

The vehicle travels at the speed set by the driver.

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, pushing the cruise control lever up or 
depressing the accelerator pedal (start-off operation) will resume follow-up cruising. If the 
start-off operation is not performed, system control continues to keep your vehicle 
stopped.
When the turn signal lever is operated and your vehicle moves to an overtaking lane while 
driving at 80 km/h (50 mph) or more, the vehicle will accelerate to help to overtake a 
passing vehicle.

4-5. Using the driving support systems

Driving

The system’s identification of what is an overtaking lane may be determined solely based on 
the location of the steering wheel in the vehicle (left side driver position versus right side 
driver position.) If the vehicle is driven to a region where the overtaking lane is on a different 
side from where the vehicle is normally driven, the vehicle may accelerate when the turn 
signal lever is operated in the opposite direction to the overtaking lane (e.g., if the driver 
normally operates the vehicle in a region where the overtaking lane is to the right but then 
drives to a region where the overtaking lane is to the left, the vehicle may accelerate when 
the right turn signal is activated).

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.

1

Press the “ON/OFF” button to acti-
vate the cruise control.

Dynamic radar cruise control indicator will 

come on and a message will be displayed 

on the multi-information display. Press the 

button again to deactivate the cruise con-

trol.
If the “ON/OFF” button is pressed and 

held for 1.5 seconds or more, the system 

turns on in constant speed control mode.

increases/decreases in accordance 
with vehicle speed. When the vehicle is 
stopped by system control, the vehicle 
stops at a certain vehicle-to-vehicle 
distance depending on the situation.

After the vehicle ahead of you starts 
off, push the lever up.
Your vehicle will also resume follow-up 
cruising if the accelerator pedal is 
depressed after the vehicle ahead of 
you starts off.
