This function is intended to alert the driver if his/her driving becomes erratic, such as if the driver is distracted or fatigued.

NOTE

The camera has certain limitations, see page 160.

A camera monitors the painted lines marking the lane in which the vehicle is traveling and compares the direction of the road with the driver’s movements of the steering wheel. The driver is alerted if the vehicle does not follow the lane smoothly.

DAC is designed to help detect a slowly changing driving pattern. It is primarily intended to be used on main roads and is not meant for use in city traffic.

WARNING

• DAC is not intended to extend the duration of driving. Always plan breaks at regular intervals to help remain alert.
• In certain cases, fatigue may not affect the driver’s behavior. In situations of this type, no warning will be provided. Therefore, it is important to take breaks at regular intervals, regardless of whether or not DAC has given a warning.

Limitations

In certain situations, DAC may provide warnings even if the driver’s driving pattern has not become erratic.

• if the driver is testing the LDW function
• in strong crosswinds
• on grooved road surfaces.
