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

Q

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

WARNING

Q

Before using dynamic radar cruise 

control with full-speed range

O

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.

O

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:

• Conditions under which the vehicle-

to-vehicle distance control mode may 

not function correctly:

O

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.

O

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.

O

Switch the dynamic radar cruise con-

trol with full-speed range setting to off, 

using the cruise control main switch 

when not in use.

Q

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.

O

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.

5-4. Using the driving support systems

WARNING

O

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.

O

Assisting the driver to operate the 

vehicle

The dynamic radar cruise control with 

full-speed range does not include 

functions which will prevent or avoid 

collisions with vehicles ahead of your 

vehicle. Therefore, if there is ever any 

possibility of danger, the driver must 

take immediate and direct control of 

the vehicle and act appropriately in 

order to ensure the safety of all 

involved.

Q

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.

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, pressing the “+RES” switch 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.

5-4. Using the driving support systems

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 differ-
ent 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.
