i-ACTIVSENSE

i-ACTIVSENSE is a collective term covering a series of advanced safety and driver support systems which make use of cameras and sensors. The systems consist of active safety and pre-crash safety systems.

These systems are designed to assist the driver in safer driving by reducing the load on the driver and helping to avert collisions or reduce their severity. However, because each system has its limitations, always drive carefully and do not rely solely on the systems.

Pre-crash safety technology is designed to assist the driver in averting collisions or reducing their severity in situations where they cannot be avoided.

The TJA is a system designed to reduce driver fatigue during traffic jams when driving on expressways or highways.

The TJA consists of a headway control function and a steering assist function.

Headway control function

The function performs headway control to maintain a constant distance between your vehicle and a vehicle ahead at a preset vehicle speed without you having to depress the accelerator or brake pedal.

Steering assist function

When vehicle lane lines are detected, the function assists your steering operation to follow the vehicle lane lines.

When vehicle lane lines are not detected, the function assists your steering operation to follow the trajectory of the vehicle ahead.

Also refer to the following information before using the TJA.

• Refer to Forward Sensing Camera (FSC) (Search).

• Refer to Front Radar Sensor (Search).

 

---

Do not rely completely on the TJA and always drive carefully:

• The TJA is not an automated driving system. Therefore, the function has limitations. Do not rely completely on the system and always stay on course using the steering wheel.

• Set a vehicle speed within the speed limit according to the road conditions and the weather conditions.

• 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 sufficiently if the vehicle ahead applies the brakes suddenly or another vehicle cuts into your lane, which could result in an accident.

Do not use the system under the following conditions. Otherwise, it may result in an accident:

• The vehicle is driven on roads other than expressways and highways.

• The vehicle is driven on roads with sharp curves or with heavy traffic where sufficient distances between vehicles cannot be kept.

• The vehicle is driven on roads where acceleration and deceleration are frequently repeated.

• The vehicle is exiting the main lane on an expressway to enter an interchange, a rest area, or a parking area.

• The vehicle is driven on slippery roads such as icy roads, snow-covered roads, and unpaved roads.

• The vehicle is driven on a long downslope.

• The vehicle is driven on a steep slope.

• A two-wheeled vehicle such as a motorcycle or bicycle is traveling ahead.

• The vehicle is being towed.

• Proximity warnings activate frequently.

• Under bad weather conditions (rain, fog, and snow).

• Tires with insufficient tread are used.

• The tire pressures are not adjusted to the specified pressure.

• Tires other than the specified size are used, such as when tire chains or temporary spare tires are used.

Switch the TJA off when it is not being used.

Leaving the TJA on when it is not in use is dangerous as it could operate unexpectedly, resulting in an accident.

Do not get out of the vehicle while the stop hold control is operating.

Getting out of the vehicle while the stop hold control is operating is dangerous as the vehicle may move unexpectedly and result in an accident. Before leaving the vehicle, switch the TJA off, shift the selector lever to the P position, and apply the parking brake.
