Highway Driving Assist operating

Highway Driving Assist operates when:

  • You have pressed the Driving Assist button after entering or driving on controlled access roads.
  • Entering or driving on controlled access roads with both Lane Following Assist and Smart Cruise Control operating.

Restarting after stopping

When Highway Driving Assist is operating, your vehicle stops if the vehicle ahead of you stops. Also, if the vehicle ahead of you starts moving within 30 seconds after the stop, your vehicle starts as well. If your vehicle has stopped and 30 seconds have passed, the "Use switch or pedal to accelerate" message appears on the instrument cluster. Depress the accelerator pedal or push the +/- switch button to accelerate.

Hands-off warning

If you take your hands off the steering wheel for several seconds, the "Place hands on steering wheel" warning message may appear on the instrument cluster, and an audible warning sounds in successive stages.

First stage: Warning message

Second stage: Warning message (red steering wheel) and audible warning

If the driver still does not have their hands on the steering wheel after the hands-off warning, the "Highway Driving Assist (HDA) system canceled" warning message may appear and Highway Driving Assist is automatically canceled.

Highway Driving Assist standby

When Smart Cruise Control is temporarily canceled while Highway Driving Assist is operating, Highway Driving Assist is in the standby state. At this time, Lane Following Assist operates normally.
