The service also includes the General Motors Advanced Automatic Crash Notification (AACN) system, making crash data available to the participating 911 centers to help them dispatch the appropriate life-saving personnel and equipment to crash scenes faster.


QuietTuned for quiet, comfortable ride

Buick Rainier's excellent balance between a quiet ride and capable handling begins with its strong body-on-frame architecture and best-in-class body stiffness, which minimizes road noise and vibration. Buick Rainier's firm body structure is complemented by QuietTuning, a comprehensive engineering initiative designed to reduce unwanted noise and harshness from entering the cabin.

Notable features include an acoustic laminate in the windshield; additional sealing at the vehicle's C- and D-pillars; and sound-absorbing materials in the engine compartment, doors and quarter panels in addition to quiet-riding Michelin tires. Attention to exterior aerodynamics, component isolation and fine-tuning of all related elements to achieve the most desirable frequency ranges also are an integral part of the QuietTuning initiative standard on every Buick vehicle.

Rainier 's smooth, comfortable ride comes from a fully independent front suspension, along with a five-link, electronically controlled rear air suspension engineered to withstand the most demanding load or towing conditions. With this system, air springs replace the standard rear coil springs for superior damping and improved isolation from road noise. Sensors manage a compressor that instantly adjusts air spring pressure to maintain a level ride height. 2007 Buick Rainier 's maximum towing capacity ranges from 6,100 to 6,700 pounds (2,722 to 3,015 kg) depending on choice of engine and other drivetrain components.

*Horsepower and torque 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 automaker to begin using this procedure and expects to use it for all newly rated engines in the future.

**Preliminary, pending SAE certification.
