- Four-wheel-disc brake system featuring smooth, quiet operation, longer pad life, and more resistance to brake pulsation
- ABS system is standard on LTZ and SS, and available on LS and LT, which helps provide improved steering control while braking. It also includes Electronic Brake Force Distribution, which helps provide optimum braking regardless of load, traction or braking speed
- Available engine- and brake-managed full-function traction control system works with the ABS system to help ensure stable acceleration on a variety of road conditions
- Pretensioners are standard on the front safety belts, helping to minimize forward movement during a frontal collision and new, more effective load-limiting retractors. The retractors have more "take-up" force, cinching the belt more tightly. Three-point safety belts are equipped in all standard seating positions
- LATCH (Lower Anchors & Tethers for CHildren) child seat attachment system is included in all second row seating positions
- Tire Pressure Monitoring System is standard on models equipped with 17- and 18-inch wheels

Impala includes features designed to enhance the vehicle structure, including lighter, more rigid front and rear bumper systems. Also, the Impala features a strengthened "safety cage" passenger compartment with the front and rear doors designed for improved energy dissipation in the event of a crash.

The OnStar system is standard on 2007 Chevy Impala. OnStar-equipped Impala models feature digital and analog coverage. OnStar's digital hardware also includes upgraded hands-free voice recognition capabilities, including more intuitive continuous digit dialing and improved voice recognition accuracy. OnStar is the leading provider of in-vehicle safety, security and information services in the United States and Canada . Using the GPS satellite network and wireless technology, OnStar features core safety services and OnStar Personal Calling that allows drivers to make and receive hands-free, voice-activated phone calls using a powerful 3-watt digital/analog system and external antenna for greater reception. The OnStar service available on the 2007 Impala includes the General Motors Advanced Automatic Crash Notification (AACN) system, making crash data available to 911 centers to potentially dispatch the appropriate life-saving personnel and equipment to crash scenes faster.

The new 7.0 Generation OnStar system offers Turn-by-Turn navigation with the optional Directions and Connections service. Turn-by-Turn navigation directs the driver through the route by using the digital readout lines in the radio head. Directions are downloaded by the OnStar advisor to the vehicle and can be played back or paused through the drive up to the destination. Besides being an easy to use system (all directions are downloaded to the car by an advisor) Turn-by-Turn offers an affordable system that is always up to date (no need to purchase map updates).

*Horsepower and torque are SAE certified. A new voluntary power and torque certification procedure developed by the SAE Engine Test Code committee was approved March 31, 2005 . This procedure (J2723) ensures fair, accurate ratings for horsepower and torque by allowing manufacturers to certify their engines through third-party witness testing. GM was the first auto manufacturer to begin using the procedure and expects to use it for all newly rated engines in the future.
