Highway Driving Assist (HDA)

The Highway Driving Assist system helps keep the vehicle between lanes, maintains distance from the vehicle ahead, and automatically adjusts vehicle speed up to the set speed limit while driving on highways.

WARNING

• HDA does not replace safe driving practices, but is a convenience feature. It is the driver's responsibility to always stay alert to surroundings and drive safely.
• HDA relies entirely on road information provided by the navigation system. It is the driver's responsibility to follow traffic laws and avoid accidents.
• Turn off Highway Driving Assist when the vehicle is being towed.
• For your safety, read the owner's manual before using the system.

✽ NOTICE

• HDA is only available on controlled-access highway entrance ramps on some highways.

❈ Controlled-access highways are roads with limited entrances and exits that allow uninterrupted, high-speed traffic flow. Only passenger cars and motorcycles are permitted on controlled-access highways.

• Additional highways may be added through navigation map updates.
