Hands off steering wheel warning

In the following situations, a warning mes-

sage urging the driver to hold the steering

wheel and the symbol shown in the illustra-

tion are displayed on the multi-information

display to warn the driver. The warning

stops when the system determines that the

driver holds the steering wheel. Always

keep your hands on the steering wheel

when using this system, regardless of warn-

ings.

O

When the system determines that the

driver is driving without holding the steer-

ing wheel while the system is operating

ates in the same way when the driver
continuously operates the steering wheel
only a small amount. The buzzer also
sounds even if the alert type is set to Steer-

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.

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

traffic rules.

When the vehicle speed exceeds
the speed notification threshold of
the speed limit sign displayed, the
sign display will be emphasized and
a buzzer will sound.

When the RSA system recognizes a
no-entry sign and detects that the
vehicle has entered a no-entry area
based on the map information of the
navigation system, the no-entry sign

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

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.

284

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.

cyclists, etc.

O

In heavy traffic

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.

Press the cruise control main
switch to activate the cruise con-

Dynamic radar cruise control indicator will

come on and a message will be displayed

on the multi-information display. Press the

Accelerate or decelerate, with
accelerator pedal operation, to the

desired vehicle speed (at or above
approximately 30 km/h [20 mph])
and press the “-SET” switch to set
the speed.

Cruise control “SET” indicator will come

on.
The vehicle speed at the moment the

switch is released becomes the set speed.
