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.

for a short amount of time.

O

The driving scene (turning, lane change,

etc.) is judged incorrectly.

O

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.

O

Stickers are attached to the rear of the

preceding vehicle.

O

A sign resembling a system compatible

sign is recognized.

O

The vehicle is driven in a country with a

different direction of traffic.

O

Side road speed signs may be detected

and displayed (if positioned in sight of the

front camera) while the vehicle is travel-

ing on the main road.

O

Roundabout exit road speed signs may

be detected and displayed (if positioned

in sight of the front camera) while travel-

ing on a roundabout.

O

Vehicles without navigation system: The

speed information displayed on the

meter and that displayed on the naviga-

tion system may be different due to the

navigation system using map data.

Q

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. (

In vehicle-to-vehicle distance con-
trol mode, the vehicle automati-
cally accelerates, decelerates and
stops to match the speed changes
of the preceding vehicle even if the
accelerator pedal is not depressed.
In constant speed control mode,
the vehicle runs at a fixed speed.
Use the dynamic radar cruise con-
trol with full-speed range on free-
ways and highways.

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:

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 on this system or assum-

ing the system ensures safety while

driving can lead to an accident, result-

ing in death or serious injury.

O

Switch the dynamic radar cruise con-

trol with full-speed range 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 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 neces-
sary for driver to pay close attention to
the vehicle’s surroundings.
