Lane departure alert function

When the system determines that the
vehicle might depart from its lane or
course

, a warning is displayed on the

multi-information display, and either a
warning buzzer will sound or the steer-
ing wheel will vibrate to alert the driver.

When the warning buzzer sounds or the
steering wheel vibrates, check the area
around your vehicle and carefully operate
the steering wheel to move the vehicle
back to the center of the lane.
When the system determines that the vehi-
cle might depart from its lane and that the
possibility of a collision with an overtaking
vehicle in the adjacent lane is high, the lane
departure alert will operate even if the turn
signals are operating.

Steering assist function

When the system determines that the
vehicle might depart from its lane or
course

, the system provides assis-

tance as necessary by operating the
steering wheel in small amounts for a
short period of time to keep the vehicle
in its lane.

When the system determines that the vehi-
cle might depart from its lane and that the
possibility of a collision with an overtaking
vehicle in the adjacent lane is high, the
steering assist function will operate even if

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.

WARNING

■

Before using the RSA

Do not rely solely upon the RSA system.

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 surround-

ings.

●

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.

196

4-5. Using the driving support systems

WARNING

●

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 cruise control main switch

when not in use.

■

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 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 sur-

roundings.

●

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.

●

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.

■

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.

●

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.

4-5. Using the driving support systems

Driving

This mode employs a radar to detect the presence of vehicles up to approximately
328 ft. (100 m) 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

WARNING

●

At entrances to freeways and high-

ways

●

When weather conditions are bad

enough that they may prevent the sen-

sors from detecting correctly (fog,

snow, sandstorm, heavy rain, etc.)

quent repeated acceleration and

Driving in vehicle-to-vehicle distance control mode

198

4-5. Using the driving support systems

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 50 mph (80 km/h) or more, the vehicle will accelerate to help to overtake a
passing vehicle.
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-
trol.

Dynamic radar cruise control indicator will

come on and a message will be displayed

on the multi-information display. Press the

switch again to deactivate the cruise con-

trol.

If the cruise control main switch is pressed

and held for 1.5 seconds or more, the sys-

tem turns on in constant speed control

mode. (
