Conditions to turn the high 

beams on/off automatically

●

When all of the following condi-

tions are met, the high beams will 

be turned on automatically (after 

approximately 1 second):

• The vehicle speed is approxi-

mately 21 mph (34 km/h) or more.

• The area ahead of the vehicle is 

dark.

• There are no vehicles ahead with 

headlights or tail lights turned on.

• There are few streetlights on the 

road ahead.

●

If any of the following conditions is 

met, the high beams will turn off 

automatically:

• The vehicle speed is below 

approximately 17 mph (27 km/h).

• The area ahead of the vehicle is 

not dark.

• Vehicles ahead have their head-

lights or tail lights turned on.

• There are many streetlights on the 

road ahead.

■

Camera sensor detection infor-

mation

●

The high beams may not be auto-

matically turned off in the following 

situations:

• When a vehicle suddenly appears 

Automatic High Beam

The Automatic High Beam 
uses a camera sensor 
located behind the upper 
portion of the windshield to 
assess the brightness of the 
lights of vehicles ahead, 
streetlights, etc., and auto-
matically turns the high 
beams on or off as neces-
sary.

WARNING

safely, taking care to observe your 

surroundings and turning the high 

beams on or off manually if nec-

• When vehicles ahead cannot be 

detected due to repeated curves, 

road dividers or roadside trees

• When vehicles ahead appear in a 

faraway lane on a wide road

• When the lights of vehicles ahead 

are not on

●

The high beams may be turned off 

if a vehicle ahead that is using fog 

lights without its headlights turned 

on is detected.

●

House lights, street lights, traffic 

signals, and illuminated billboards 

or signs and other reflective 

objects may cause the high 

beams to change to the low 

beams, or the low beams to 

remain on.

●

The following factors may affect 

the amount of time taken for the 

high beams to turn on or off:

• The brightness of the headlights, 

fog lights, and tail lights of vehi-

cles ahead

• The movement and direction of 

vehicles ahead

• When a vehicle ahead only has 

operational lights on one side

• When a vehicle ahead is a 

two-wheeled vehicle

• The condition of the road (gradi-

ent, curve, condition of the road 

surface, etc.)

• The number of passengers and 

amount of luggage in the vehicle

●

The high beams may turn on or off 

unexpectedly.

●

Bicycles or similar vehicles may 

not be detected.

●

In the following situations the sys-

tem may not be able to correctly 

detect the surrounding brightness 

level. This may cause the low 

beams to remain on or the high 

beams to flash or dazzle pedestri-

ans or vehicles ahead. In such a 

case, it is necessary to manually 

switch between the high and low 

beams.

WARNING

■

When refueling the vehicle

Observe the following precautions 

while refueling the vehicle. Failure 

to do so may result in death or 

serious injury.

●

After exiting the vehicle and 

before opening the fuel door, 

touch an unpainted metal sur-

face to discharge any static 

electricity. It is important to dis-

charge static electricity before 

refueling because sparks result-

ing from static electricity can 

cause fuel vapors to ignite while 

refueling.

●

Always hold the grips on the 

fuel tank cap and turn it slowly 

to remove it.

A whooshing sound may be 

heard when the fuel tank cap is 

loosened. Wait until the sound 

cannot be heard before fully 

removing the cap. In hot 

weather, pressurized fuel may 

spray out of the filler neck and 

cause injury.

●

Do not allow anyone that has 

not discharged static electricity 

from their body to come close to 

an open fuel tank.

●

Do not inhale vaporized fuel.

Fuel contains substances that 

are harmful if inhaled.

●

Do not smoke while refueling 

the vehicle.

Doing so may cause the fuel to 

ignite and cause a fire.

●

Do not return to the vehicle or 

touch any person or object that 

is statically charged.

This may cause static electricity 

to build up, resulting in a possi-

ble ignition hazard.

■

When refueling

Observe the following precautions 

to prevent fuel overflowing from 

the fuel tank:

●

Securely insert the fuel nozzle 

into the fuel filler neck.

●

Stop filling the tank after the fuel

●

The driver is solely responsible 

for safe driving. Always drive 

safely, taking care to observe 

your surroundings.

Do not use the pre-collision sys-

tem instead of normal braking 

operations under any circum-

stances. This system will not 

prevent collisions or lessen col-

lision damage or injury in every 

situation. Do not overly rely on 

this system. Failure to do so 

may lead to an accident, result-

ing in death or serious injury.

WARNING

●

Although this system is 

designed to help avoid a colli-

sion or help reduce the impact 

of the collision, its effectiveness 

may change according to vari-

ous conditions, therefore the 

system may not always be able 

to achieve the same level of 

performance.

Read the following conditions 

carefully. Do not overly rely on 

this system and always drive 

carefully.

• Conditions under which the sys-

tem may operate even if there is 

no possibility of a collision:

●

Do not attempt to test the oper-

ation of the pre-collision system 

yourself.

Depending on the objects used 

for testing (dummies, card-

board objects imitating detect-

able objects, etc.), the system 

may not operate properly, possi-

bly leading to an accident.

■

Pre-collision braking

●

When the pre-collision braking 

function is operating, a large 

amount of braking force will be 

applied.

●

If the vehicle is stopped by the 

operation of the pre-collision 

braking function, the pre-colli-

sion braking function operation 

will be canceled after approxi-

mately 2 seconds. Depress the 

brake pedal as necessary.

●

The pre-collision braking func-

tion may not operate if certain 

operations are performed by the 

driver. If the accelerator pedal is 

being depressed strongly or the 

steering wheel is being turned, 

the system may determine that 

the driver is taking evasive 

action and possibly prevent the 

pre-collision braking function 

from operating.

●

In some situations, while the 

pre-collision braking function is 

operating, operation of the func-

tion may be canceled if the 

accelerator pedal is depressed 

strongly or the steering wheel is 

turned and the system deter-

mines that the driver is taking 

evasive action.

●

If the brake pedal is being 

depressed, the system may 

determine that the driver is tak-

ing evasive action and possibly 

delay the operation timing of the 

pre-collision braking function.

■

Emergency steering assist

●

As emergency steering assist 

operation will be canceled when 

the system determines that lane 

departure prevention function 

has been completed.

●

Emergency steering assist may 

not operate or may be cancel in 

the following cases as the sys-

tem may determine the driver is 

taking actions.

• If the accelerator pedal is being 

depressed strongly, the steering 

wheel is being operated sharply, 

the brake pedal is being 

depressed or the turn signal 

lever is being operated. In this 

case, the system may deter-

mine that the driver is taking 

evasive action and the emer-

gency steering assist may not 

operate.

LTA (Lane Tracing 

Assist)

While driving on a road with 
clear white (yellow) lane 
lines, the LTA system warns 
the driver if the vehicle may 
deviate from the current 
lane or course

*

, and also 

can slightly operate the 
steering wheel to help avoid 
deviation from the lane or 
course

*

. Also, while the 

dynamic radar cruise con-
trol with full-speed range 
(



P.257) is operating, this 

system will operate the 
steering wheel to maintain 
the vehicle’s lane position.

The LTA system recognizes 
white (yellow) lane lines or a 
course

WARNING

■

Before using LTA system

●

Do not rely solely upon the LTA 

system. The LTA system does 

not automatically drive the vehi-

cle or reduce the amount of 

attention that must be paid to 

the area in front of the vehicle. 

The driver must always assume 

full responsibility for driving 

safely by paying careful atten-

tion to the surrounding condi-

tions and operating the steering 

wheel to correct the path of the 

vehicle. Also, the driver must 

take adequate breaks when 

fatigued, such as from driving 

for a long period of time.

●

Failure to perform appropriate 

driving operations and pay care-

ful attention may lead to an 

accident, resulting in death or 

serious injury.

■

Situations unsuitable for LTA 

system

In the following situations, use the 

LTA switch to turn the system off. 

Failure to do so may lead to an 

accident, resulting in death or 

serious injury.

●

face which is slippery due to 

rainy weather, fallen snow, 

freezing, etc.

●

Vehicle is driven on a snow-cov-

ered road.

●

White (yellow) lines are difficult 

to see due to rain, snow, fog, 

dust, etc.

●

Vehicle is driven in a temporary 

lane or restricted lane due to 

construction work.

●

Vehicle is driven in a construc-

tion zone.

excessively worn, or when the 

tire inflation pressure is low.

●

When your vehicle is towing a 

trailer or during emergency tow-

ing.

■

Preventing LTA system mal-

functions and operations per-

formed by mistake

●

Do not modify the headlights or 

place stickers, etc. on the sur-

face of the lights.

●

Do not modify the suspension 

etc. If the suspension etc. needs 

to be replaced, contact your 

Toyota dealer.

●

Do not install or place anything 

on the hood or grille. Also, do 

not install a grille guard (bull 

bars, kangaroo bar, etc.).

●

If your windshield needs 

repairs, contact your Toyota 

dealer.

■

Conditions in which functions 

may not operate properly

In the following situations, the 

functions may not operate prop-

erly and the vehicle may depart 

from its lane. Drive safely by 

always paying careful attention to 

your surroundings and operate

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 sur-

roundings.

●

The dynamic radar cruise con-

trol with full-speed range pro-

vides 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:

rectly: 



P.268

●

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 with full-speed range 

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 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 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 vehi-

cle’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 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 pre-

vent or avoid collisions with vehi-

cles 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.

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 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, system 
control continues to keep your vehicle stopped.

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.

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.

■

Automatic cancelation of vehi-

cle-to-vehicle distance control 

mode

Vehicle-to-vehicle distance control 

mode is automatically canceled in 

the following situations.

●

VSC is activated.

●

TRAC is activated for a period of 

time.

●

When the VSC or TRAC system is 

turned off.

●

When snow mode is set.

●

The sensor cannot detect cor-

rectly because it is covered in 

some way.

●

Pre-collision braking is activated.

●

The parking brake is operated.

●

The vehicle is stopped by system 

control on a steep incline.

The following are detected when 

the vehicle has been stopped by 

system control:

• The driver is not wearing a seat 

belt.

• The driver’s door is opened.

• The vehicle has been stopped for 

about 3 minutes

If vehicle-to-vehicle distance control 

mode is automatically canceled for 

any reasons other than the above, 

there may be a malfunction in the 

system. Contact your Toyota dealer.

■

Automatic cancelation of con-

stant speed control mode

Constant speed control mode is 

automatically canceled in the follow-

ing situations:

●

Actual vehicle speed is more than 

approximately 10 mph (16 km/h) 

below the set vehicle speed.

●

Actual vehicle speed falls below 

approximately 20 mph (30 km/h).

●

VSC is activated.

●

TRAC is activated for a period of 

time.

●

When the VSC or TRAC system is 

turned off.

●

Pre-collision braking is activated.

●

The parking brake is operated.

If constant speed control mode is 

automatically canceled for any rea-

sons other than the above, there 

may be a malfunction in the system. 

Contact your Toyota dealer.

Situations in which the curve 

speed reduction function may 

not operate

In situations such as the following, 

the curve speed reduction function 

may not operate:

●

When the vehicle is being driven 

around a gentle curve

●

When the accelerator pedal is 

being depressed

●

When the vehicle is being driven 

around an extremely short curve

■

Brake operation

A brake operation sound may be 

heard and the brake pedal response 

may change, but these are not mal-

functions.

■

Warning messages and buzzers 

for dynamic radar cruise con-

trol with full-speed range

Warning messages and buzzers are 

used to indicate a system malfunc-

tion or to inform the driver of the 

need for caution while driving. If a 

warning message is shown on the 

multi-information display, read the 

message and follow the instructions.

When the sensor may not be 

correctly detecting the vehicle 

ahead

In the case of the following and 

depending on the conditions, oper-

ate the brake pedal when decelera-

tion of the system is insufficient or 

operate the accelerator pedal when 

acceleration is required.
As the sensor may not be able to 

correctly detect these types of vehi-

cles, the approach warning
