Here are the active safety features on the 2014 Impala designed to help drivers avoid crashes:
- Full-speed-range adaptive cruise control – Radar technology senses ahead and adjusts the Impala’s speed from a complete stop to full acceleration. It is the first application in a Chevrolet.
- Collision mitigation braking – Another Chevy first: Radar technology detects a possible crash threat and alerts the driver. If the driver does not appear to react quickly enough or doesn’t react at all, this feature intervenes to apply the brakes in an effort to avoid the crash.
- Forward collision alert – Camera technology detects a possible crash threat and alerts the driver visually and audibly, giving him or her time to stop and/or change course. If a crash occurs, the Impala is equipped with OnStar, and a specially trained advisor is connected to the vehicle. If the driver requests help or can’t answer, emergency responders are sent to the precise GPS location.
- Lane departure warning – A camera-based lane-detection system identifies traffic lane markings and provides audible alerts in cases of unintended lane changes.
- Side blind zone alert – Using radar sensors on both sides of the vehicle, the system “looks” for other vehicles in the blind zone areas of the Impala and indicates their presence with LED-lit symbols in the outside mirrors.
- · Rear cross traffic alert – Based on the radar sensors of side blind zone alert, it warns the driver of vehicles in traffic when backing out of a parking spot – including angled parking. Visual and audible alerts are triggered if moving vehicles are detected.
- Rear vision camera with dynamic guidelines – With a display in the center stack infotainment system, the camera provides a view of objects directly behind the Impala, while the dynamic guidelines provide a reference that helps make parking and other maneuvers easier.
- Rear park assist – Uses sensors in the rear bumper to detect objects directly behind the vehicle and provides an alert for the driver.
- Brake pre-fill feature – Another Chevy first: Radar technology detects a possible crash threat and the system increases the hydraulic pressure in the brake lines, anticipating a driver’s hard braking. This quickens the response time and shortens stopping distances (included with 20-inch wheels on uplevel models).
- Hill hold/start assist – On hills, applies the brakes for about 1.5 seconds to prevent the car from rolling when the driver moves his or her foot from the brake to the accelerator pedal.
