4-5. Using the driving support systems

WARNING

●

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 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 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

267

4-5. Using the driving support systems

Driving

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.

WARNING

●

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

●

During emergency towing

●

When an approach warning buzzer is 

heard often

Driving in vehicle-to-vehicle distance control mode

4-5. Using the driving support systems

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.
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).
