The TJA may not be able to detect a

vehicle ahead depending on the type

of vehicle ahead and its conditions,

the weather conditions, and the road

conditions. Additionally, the system

might be unable to decelerate

su

ciently if a vehicle ahead applies

the brakes suddenly, another vehicle

cuts into the driving lane, or the

di

erence in vehicle speed between

your vehicle and the vehicle ahead is

larger, which could result in an

accident. Check the surrounding

conditions and always drive carefully

while keeping a safe distance from

vehicles ahead and on-coming

vehicles.

 

For the purposes of safety, switch the

TJA o

 when it is not being used.

Leaving the TJA turned on when it is

not in use is dangerous as it could

operate unexpectedly, resulting in an

accident.

 

Do not use the TJA under the

following conditions. Otherwise, it

may result in an accident.

General roads other than

expressways or highways (Driving

under these conditions using the TJA

is not possible.)

Roads with sharp curves and where

vehicle tra

c is heavy with

insu

cient space between vehicles,

or roads where frequent and

repetitive acceleration and

deceleration occur (Driving under

these conditions using the TJA is not

possible).

When entering and exiting

interchanges, service areas, and

parking areas of expressways (If you

exit an expressway while headway

control is in use, the vehicle ahead

will no longer be tracked and your

vehicle may accelerate to the set

speed).

Slippery roads such as icy or

snow-covered roads (Tires could spin

causing you to lose vehicle control,

or the stop hold control may not

operate.)

Long, descending slopes (to

maintain distance between vehicles,

the system automatically and

continuously applies the brakes

which could result in the loss of

brake power.)

Two-wheeled vehicles such as

motorcycles or bicycles are ahead.

(Automatic transmission vehicle)

Slopes with a steep gradient (The

vehicle ahead may not be detected

correctly, your vehicle may slip while

stopped by the stop hold control, or

it may accelerate suddenly after it

starts moving.)

Driving under bad weather

conditions (rain, fog, and snow).

The vehicle is driven on slippery

roads such as icy or snow -covered

roads and unpaved roads (Tires

could spin causing you to lose

vehicle control, or the stop hold

control may not operate.)

Tires of a di

erent speci

fi

ed size are

used, such as a temporary spare tire.

Tires with insu

cient tread are used.

The tire pressures are not adjusted to

the speci

fi

ed pressure.

The vehicle is being used to tow a

camper or boat trailer.

Tire chains are used.
