4-5. Using the driving support systems

available from the navigation system, 
the sign will be displayed on the multi-
information display.

When the driving support system 
information is selected, a maximum 
of 3 signs can be displayed. 
(

P.85)

When a tab other than the driving 
support system information is 
selected, the following types of road 
signs will be displayed. (

P.85)

• Speed limit sign
• Do Not Enter sign (when notification is 

necessary)

If signs other than speed limit signs are rec-
ognized, they will be displayed in an over-
lapping stack under the current speed limit 
sign.

The following types of road signs, 

including electronic signs and blinking 
signs, are recognized.

A non-official or a recently introduced traf-
fic sign may not be recognized.

 : Speed limit

 : Do Not Enter

 : Stop

 : Yield

In the following situations, the RSA sys-
tem will notify the driver.

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 
do not enter sign and determines 
that your vehicle has entered a no-
entry area, the displayed sign will 
flash and a buzzer will sound.

Depending on the situation, a notifica-
tion function may not operate properly.

Conditions in which the function may 

not operate or detect correctly

In the following situations, RSA does not 

operate normally and may not recognize 

signs, display the incorrect sign, etc. How-

ever, this does not indicate a malfunction.

The front camera is misaligned due to a 

strong impact being applied to the sen-

sor, etc.

Dirt, snow, stickers, etc. are on the wind-

shield near the front camera.

In inclement weather such as heavy rain, 

fog, snow or sand storms.

Light from an oncoming vehicle, the sun, 

etc. enters the front camera.

The sign is dirty, faded, tilted or bent.

The contrast of electronic sign is low.

All or part of the sign is hidden by the 

leaves of a tree, a pole, etc.

The sign is only visible to the front camera 

for a short amount of time.

The driving scene (turning, lane change, 

etc.) is judged incorrectly.

If a sign not appropriate for the currently 

traveled lane, but the sign exists directly 

after a freeway branches, or in an adja-

cent lane just before merging.

Stickers are attached to the rear of the 

preceding vehicle.

A sign resembling a system compatible 

sign is recognized.

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.

Roundabout exit road speed signs may 

be detected and displayed (if positioned 

in sight of the front camera) while travel-

ing on a roundabout.

The front of the vehicle is raised or low-

ered due to the carried load.

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.212

• Conditions under which the vehicle-

to-vehicle distance control mode may 

not function correctly: 

P.212

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.

Driving

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.

206

4-5. Using the driving support systems

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.)

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

Driving

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.

A brake operation sound may be heard and 

the brake pedal response may change, but 

these are not malfunctions.

Warning messages and buzzers for 

dynamic radar cruise control with full-

speed range

Warning messages and buzzers are used to 

indicate a system malfunction or to inform 

the driver of the need for caution while driv-

ing. If a warning message is shown on the 

multi-information display, read the message 

and follow the instructions. (

detecting the vehicle ahead

In the case of the following and depending 

on the conditions, operate the brake pedal 

when deceleration of the system is insuffi-

cient or operate the accelerator pedal 

when acceleration is required. 

As the sensor may not be able to correctly 

detect these types of vehicles, the approach

BSM (Blind Spot Monitor)

The Blind Spot Monitor is a system 
that uses rear side radar sensors 
installed on the inner side of the 
rear bumper on the left and right 
side to assist the driver in confirm-
ing safety when changing lanes.

WARNING

Cautions regarding the use of the 

function

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 nec-

essary.

WARNING

To ensure the system can operate 

properly

Blind Spot Monitor sensors are installed 

behind the left and right sides of the rear 

bumper respectively. Observe the fol-

lowing to ensure the Blind Spot Monitor 

can function correctly.

Keep the sensors and the surrounding 

areas on the rear bumper clean at all 

times. 

If a sensor or its surrounding area on 

the rear bumper is dirty or covered 

with snow, the Blind Spot Monitor may 

not operate and a warning message 

(

P.214) will be displayed. In this situ-

ation, clear off the dirt or snow and 

drive the vehicle with the operation 

conditions of the BSM function 

(

P.216) satisfied for approximately 

10 minutes. If the warning message 

does not disappear, have the vehicle 

inspected by your Lexus dealer.

Do not subject a sensor or its sur-

rounding area on the rear bumper to a 

strong impact. 

If a sensor is moved even slightly off 

position, the system may malfunction 

and vehicles may not be detected cor-

rectly. 

In the following situations, have your 

vehicle inspected by your Lexus 

dealer.

• A sensor or its surrounding area is 

subject to a strong impact.

• If the surrounding area of a sensor is 

scratched or dented, or part of them 

has become disconnected.

Do not disassemble the sensor.

Vehicles that can be detected by the Blind Spot Monitor

The Blind Spot Monitor uses rear side radar sensors to detect the following vehi-
cles traveling in adjacent lanes and advises the driver of the presence of such vehi-
cles via the indicators on the outside rear view mirrors.

Vehicles that are traveling in areas that are not visible using the outside rear 
view mirrors (the blind spots)

Vehicles that are approaching rapidly from behind in areas that are not visible 
using the outside rear view mirrors (the blind spots)
