4-5. Using the driving support systems

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.

●

Vehicle is driven on a road sur-

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.

●

A spare tire, tire chains, etc. are 

equipped.

●

When the tires have been 

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 

the steering wheel to correct the 

path of the vehicle without relying 

solely on the functions.

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:

P.274

●

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.

WARNING

●

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.

■

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 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

●

When your vehicle is towing a 

trailer or during emergency tow-

ing

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 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.
