Safety and security

2007 Silverado delivers 360 degrees of safety protection through a stronger frame and body structure as well as industry- and segment-leading technology. It is also designed to provide increased compatibility with other vehicles. New features include segment-first StabiliTrak electronic stability control with rollover mitigation technology, roof-mounted head curtain side air bags, which are integrated into strengthened chassis and body structures to provide excellent passenger protection, and segment-first safety belt pretensioners that activate during a rear-end crash. The head curtain side air bags are available on LT and LTZ models.

Driver control dynamics are enhanced by wider front and rear tracks, as well as more responsive suspensions - including a new coil-over-shock front suspension design and rack-and-pinion steering. Additional safety features are offered on Silverado, including factory-installed remote vehicle starting (segment exclusive), Autotrac active transfer case to help keep the vehicle sure-footed in slippery driving situations, Ultrasonic Rear Parking Assist and a revised, easier-to-use tire pressure monitoring system.

All retail models come standard with the OnStar Generation 7 system, including a one-year subscription to the Safe & Sound plan. The OnStar service includes the General Motors Advanced Automatic Crash Notification (AACN) system, making crash data available to emergency services to potentially dispatch the appropriate life-saving personnel and equipment to crash scenes faster. If the vehicle is in a crash that activates an air bag, the OnStar system automatically notifies an OnStar advisor who will check on the occupants or summon emergency help if necessary. OnStar also can assist authorities in locating a vehicle if it is reported stolen and provides remote door-unlocking service (for vehicles equipped with power locks).

* 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.
