Intended for highway use, Full-Speed Range Dynamic Radar Cruise Control (DRCC) is an adaptive cruise control system that is designed to be set at speeds above 20 mph. The system uses vehicle-to-vehicle distance control to help maintain a preset distance from the vehicle ahead of you with enhancements that provide natural speed transitions during changing traffic conditions.

When white/yellow lane markings or certain road-edge boundaries are detected at speeds above 30 mph, Lane Departure Alert with Steering Assist (LDA w/SA) is designed to issue an audio/visual lane departure warning if an inadvertent lane departure is detected. If the driver does not take corrective action, the system is also designed to provide gentle corrective steering for lane-keeping assistance.

When Full-Speed Range Dynamic Radar Cruise Control (DRCC) is enabled and lane markers are detected, Lane Tracing Assist (LTA) uses the lines on the road and/or preceding vehicles to provide active driving assistance and help keep the vehicle centered in its lane. While LTA is activated, the Emergency Driving Stop System (EDSS) is designed to help detect a driver who is inattentive or nonresponsive, such as during a medical emergency. This feature can bring the vehicle to a stop if the driver does not respond to alerts to take control.

Using an intelligent camera, Road Sign Assist (RSA) is designed to detect speed limit signs, stop signs, Do Not Enter signs, yield signs and certain warning signs, and display an icon of the sign on the Multi-Information Display (MID).

The Automatic High Beams (AHB) are designed to help you see more clearly at night. At speeds above 21 mph, the AHB system is designed to detect the headlights of oncoming vehicles and taillights of preceding vehicles, then automatically toggle between high and low beams accordingly.

When system operating conditions are met, using Grand Highlander’s camera and radar, Proactive Driving Assist (PDA) provides gentle braking into curves, or gentle braking and/or steering, to help support driving tasks such as distance control between your vehicle and a preceding vehicle, pedestrian or bicyclist.
