The Lane Keeping Assist System on the Honda Civic Si here at Steve Hopkins Honda is designed to prevent the driver from unintentionally drifting out of their lane. When enabled, the system uses a camera positioned on the windshield to monitor lane markings. If it detects that you are starting to leave your lane without indicating or signaling, it will alert you with visual and audible warnings.
If you don’t react quickly enough and cross into another lane, it will apply gentle pressure on the brakes for 2 seconds in order to bring your vehicle back into its own space. This can be used on highways or in traffic as well as during parking lot maneuvers when there aren’t many other cars around.
The cruise control system allows the Honda Civic Si to maintain a set distance from the vehicles in front of it. Using this feature, you can use your car to travel at speeds that are slower than those required for driving without cruise control. For example, if you're driving on a highway in Fairfield, CA and there are no traffic or weather conditions that require you to drive faster than 55 mph. You can also use it when traveling in bumper-to-bumper traffic or in stop-and-go traffic when there is ample space between vehicles but not enough space for safe braking.
