operating, if the system detects that a vehi-

cle is quickly approaching in the lane

toward which the turn signal is operated,

the steering assist may slightly steer the

vehicle away from the lane while a buzzer is

sounding, the steering wheel is vibrating,

and a warning display is displayed on the

multi-information display, to help prevent

the vehicle from entering the lane and alert

the driver of the approaching vehicle.

■

Hands off steering wheel alert

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.
Depending on the vehicle condition and

road conditions, the warning may not oper-

ate. Also, if the system determines that the

vehicle is driving around a curve, warnings

will occur earlier than during straight-lane

driving.

●

When the system determines that the

driver is driving without holding the steer-

ing wheel while the system is operating

If the driver continues to keep their hands

off of the steering wheel, the buzzer

sounds, the driver is warned and the func-

tion is temporarily canceled. This warning

also operates 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

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.

• When the sensor may not be correctly

detecting the vehicle ahead:

P.245

• Conditions under which the vehi-

cle-to-vehicle distance control mode

may not function correctly:

P.246

●

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.

A
B
C
D

●

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.

WARNING

●

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

●

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

LS500_OM_(U)_1809

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

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 a left lane while driving at
50 mph (80 km/h) or more, the vehicle will quickly accelerate to help to overtake a pass-
ing vehicle.

Example of acceleration

Cautions regarding the use of the sys-

tem

The driver is solely responsible for safe

driving. Always drive safely, taking care

to observe your surroundings.
The Blind Spot Monitor is a supplemen-

tary function which alerts the driver that a

vehicle is in a blind spot of the outside

rear view mirrors or is approaching rap-

idly from behind into a blind spot. Do not

overly rely on the Blind Spot Monitor. As

the function cannot judge if it is safe to

change lanes, over reliance could lead to

an accident resulting in death or serious

injury.
As the system may not function correctly

under certain conditions, the driver’s own

visual confirmation of safety is necessary.
