With the cruise control off, 
press and hold the cruise 
control main switch for 1.5 
seconds or more.

Immediately after the switch is 

pressed, the dynamic radar cruise 

control indicator will come on. After-

wards, it switches to the cruise con-

trol indicator.
Switching to constant speed control 

mode is only possible when operat-

ing the switch with the cruise con-

trol off.

Accelerate or decelerate, 
with accelerator pedal opera-
tion, to the desired vehicle 
speed (at or above approxi-
mately 20 mph [30 km/h]) 
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.

Dynamic radar cruise control 

with full-speed range can be set 

when

The shift lever is in D.

The desired set speed can be set 

when the vehicle speed is approx-

imately 20 mph (30 km/h) or more. 

(However, when the vehicle speed 

is set while driving at below 

approximately 20 mph [30 km/h], 

the set speed will be set to 

approximately 20 mph [30 km/h].)

Accelerating after setting the 

vehicle speed

The vehicle can accelerate by oper-

ating the accelerator pedal. After 

accelerating, the set speed 

resumes. However, during vehi-

cle-to-vehicle distance control 

mode, the vehicle speed may 

decrease below the set speed in 

order to maintain the distance to the 

preceding vehicle.

When the vehicle stops while 

follow-up cruising

Pressing the “+RES” switch while 

the vehicle ahead stops will 

resume follow-up cruising if the 

vehicle ahead starts off within 

approximately 3 seconds after the 

switch is pressed.

If the vehicle ahead starts off 

within 3 seconds after your vehicle 

stops, follow-up cruising will be 

resumed.

WARNING

Before using dynamic radar 

cruise control

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 sur-

roundings.

The dynamic radar cruise con-

trol provides driving assistance 

to reduce the driver’s burden. 

However, there are limitations to 

the assistance provided.

Read the following conditions 

carefully. Do not overly rely on 

this system and always drive 

carefully.

• When the sensor may not be 

correctly detecting the vehicle 

ahead: 

P.220

• Conditions under which the 

vehicle-to-vehicle distance con-

trol mode may not function cor-

rectly: 

P.220

212

4-5. Using the driving support systems

WARNING

Set the speed appropriately 

depending on the speed limit, 

traffic flow, road conditions, 

weather conditions, etc. The 

driver is responsible for check-

ing the set speed.

Even when the system is func-

tioning normally, the condition of 

the preceding vehicle as 

detected by the system may dif-

fer from the condition observed 

by the driver. Therefore, the 

driver must always remain alert, 

assess the danger of each situ-

ation and drive safely. Relying 

solely on this system or assum-

ing the system ensures safety 

while driving can lead to an 

accident, resulting in death or 

serious injury.

Switch the dynamic radar cruise 

control setting to off, using the 

cruise control main switch when 

not in use.

Cautions regarding the driv-

ing assist systems

Observe the following precau-

tions, as there are limitations to 

the assistance provided by the 

system.

Failure to do so may cause an 

accident resulting in death or seri-

ous injury.

Assisting the driver to measure 

following distance

The dynamic radar cruise control 

is only intended to help the driver 

in determining the following dis-

tance between the driver’s own 

vehicle and a designated vehicle 

traveling ahead. It is not a mecha-

nism that allows careless or inat-

tentive 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 vehi-

cle’s surroundings.

Assisting the driver to judge 

proper following distance

The dynamic radar cruise control 

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 neces-

sary 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 

does not include functions which 

will prevent or avoid collisions 

with vehicles ahead of your vehi-

cle. 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.

WARNING

Situations unsuitable for 

dynamic radar cruise control

Do not use dynamic radar cruise 

control in any of the following situ-

ations. 

Doing so may result in inappropri-

ate speed control and could 

cause an accident resulting in 

death or serious injury.

Roads where there are pedes-

trians, cyclists, etc.

In heavy traffic

On roads with sharp bends

On winding roads

On slippery roads, such as 

those covered 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 pre-

vent the sensors from detecting 

correctly (fog, snow, sand-

storm, heavy rain, etc.)

When there is rain, snow, etc. 

on the front surface of the radar 

or front camera

In traffic conditions that require 

frequent repeated acceleration 

and deceleration

During emergency towing

When an approach warning 

buzzer is heard often

214

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 vehi-
cle-to-vehicle following distance, and operates to maintain a suitable 
following distance from the vehicle ahead. The desired vehi-
cle-to-vehicle distance can also be set by operating the vehi-
cle-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 nec-
essary, 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 suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the turn signal lever is operated and your vehicle moves to an over-
taking lane while driving at 50 mph (80 km/h) or more, the vehicle will accel-
erate 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 vehi-
cle 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.

The RSA system recognizes 
specific road signs using 
the front camera 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 recog-
nized 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. RSA is a system which 

supports the driver by providing 

information, but it is not a replace-

ment for a driver’s own vision and 

awareness. Drive safely by 

always paying careful attention to 

the traffic rules.

• Speed limit sign

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

When a tab other than the 
driving support system infor-
mation is selected, the follow-
ing types of road signs will be 
displayed.  (

• Speed limit sign
• Do Not Enter sign (when notifica-

tion is necessary)

If signs other than speed limit signs 
are recognized, they will be dis-

played in an overlapping stack 
under the current speed limit sign.

The following types of road 
signs, including electronic signs 
and blinking signs, are dis-
played.

A non-official or a recently intro-
duced traffic sign may not be dis-
played.

When the RSA system recog-
nizes 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

display

In the following situations, a dis-

played speed limit sign and/or do 

not enter sign will stop being dis-

played automatically:

No sign has been recognized for a 

certain distance.

The road changes due to a left or 

right turn, etc.

In the following situations, stop and 

yield signs will stop being displayed 

automatically:

The system determines that your 

vehicle has passed the sign.

The road changes due to a left or 

right turn, etc.

Conditions in which the func-

tion 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. However, this 

does not indicate a malfunction.

The front camera is misaligned 

due to a strong impact being 

applied to the sensor, etc.

Dirt, snow, stickers, etc. are on the 

windshield 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 cam-

era.

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 adjacent lane 

just before merging.

Stickers are attached to the rear of 

the preceding vehicle.

A sign resembling a system com-

patible sign is recognized.

Side road speed signs may be 

detected and displayed (if posi-

tioned in sight of the front camera) 

while the vehicle is traveling on 

the main road.

Roundabout exit road speed signs 

may be detected and displayed (if 

positioned in sight of the front 

camera) while traveling on a 

roundabout.

The front of the vehicle is raised or 

lowered due to the carried load.

The surrounding brightness is not 

sufficient or changes suddenly.

When a sign intended for trucks, 

etc. is recognized.

The speed information displayed 

on the meter and on the naviga-

tion system may be different due
