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 paying careful attention to your sur-

roundings.

●

The dynamic radar cruise control with full-speed range 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. 304

• Conditions under which the vehicle-to-vehicle distance control mode

may not function correctly: 



P. 305

●

Set the speed appropriately depending 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 control with full-speed range setting to off,

using the cruise control main switch when not in use.

WARNING

■

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 following 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 vehicle and a designated vehicle traveling ahead. It is not a mecha-

nism 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 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 neces-

sary 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.

WARNING

■

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

following 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 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 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

camera

●

In traffic conditions that require frequent repeated acceleration and decel-

eration

●

During emergency towing

●

When an approach warning buzzer is heard often

294

4-5. Using the driving support systems

CAMRY_U

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 distance, and operates to maintain a suitable fol-
lowing distance from the vehicle ahead. The desired vehicle-to-vehi-
cle 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 suffi-
ciently 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 system 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, sys-
tem control continues to keep your vehicle stopped.

CAMRY_U

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
accelerate to help to overtake a passing vehicle.

The system’s identification of what is an overtaking lane may be deter-
mined 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).

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
control.

Dynamic radar cruise control indi-
cator will come on and a message
will be displayed on the multi-infor-
mation display.

Press the switch again to deacti-
vate the cruise control.

If the cruise control main switch is pressed and held for 1.5 seconds or
more, the system turns on in constant speed control mode. (

P. 301)

Accelerate or decelerate, with
accelerator pedal operation, to
the desired vehicle speed (at or
above approximately 20 mph
[30 km/h]) and press the “- SET”
switch to set the speed.

Cruise control “SET” indicator will
come on.

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 paying careful attention to your sur-

roundings.

●

The dynamic radar cruise control 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. 320

• Conditions under which the vehicle-to-vehicle distance control mode

may not function correctly: 



P. 321

●

Set the speed appropriately depending 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 control setting to off, using the cruise con-

trol main switch when not in use.

WARNING

■

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 following distance

The dynamic radar cruise control is only intended to help the driver in

determining the following distance between the driver’s own vehicle and a

designated vehicle traveling ahead. It is not a mechanism that allows care-

less 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 sur-

roundings.

●

Assisting the driver to judge proper following distance

The dynamic radar cruise control determines whether the following dis-

tance 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 does not include functions which will pre-

vent 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.

WARNING

■

Situations unsuitable for dynamic radar cruise control

Do not use dynamic radar cruise control in any of the following 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 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 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

camera

●

In traffic conditions that require frequent repeated acceleration and decel-

eration

●

During emergency towing

●

When an approach warning buzzer is heard often

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 distance, and operates to maintain a suitable fol-
lowing distance from the vehicle ahead. The desired vehicle-to-vehi-
cle 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 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 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
accelerate to help to overtake a passing vehicle.

The system’s identification of what is an overtaking lane may be deter-
mined 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).

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.
