Here's something I got from the GM website. 2006 CHEVROLET TAHOE – FULL-SIZE CAPABILITY WITH FULL-SIZE COMFORT Chevy Tahoe enters 2006 with evolutionary changes that lay the groundwork for the next-generation model. Tahoe retains the premium appointments, refined ride and handling, and outstanding levels of safety and capability that helped make it the industry’s best-selling full-size SUV in 2004. The 2006 changes include: Integrated OnStar/XM Satellite Radio antenna – A single antenna unit replaces the previous two, for a smoother appearance. The new, combined antenna is located on the left-front corner of the roof. Relocated catalytic converters – The catalytic converters are moved closer to the engine to meet improved emissions performance guidelines. Standard tire pressure monitoring system – All Tahoe models have a standard GM tire pressure monitoring system, which uses an electronic signal on the driver information center to warn of a low-pressure condition. Manual park brake adjuster – This new park brake adjuster system offers enhanced performance compared with the previous system. Vortec 5300 Flex-Fuel V-8 available for all equipment groups – All retail equipment groups can add the Vortec 5300 Flex-Fuel engine, which can operate on a combination of gasoline and E85 ethanol fuel. Proven powertrains Tahoe’s powertrain lineup includes GM’s Vortec 4800 4.8L V-8 as standard, rated at 285 horsepower (213 kw) and 295 lb.-ft. (400 Nm) of torque. Owners seeking even more power and capability can choose the Vortec 5300 5.3L V-8, which generates 295 horsepower (220 kw) and 330 lb.-ft. (447 Nm) of torque. GM’s Hydra-Matic 4L60-E four-speed automatic transmission is standard with both engines. Tahoe can tow up to 7,700 pounds (3,493 kg) when properly equipped. Introduced in ’05, Tahoe’s all-electric cooling system helps improve fuel economy through reduced parasitic loss on the engine – there is no engine-driven fan. It also enhances air conditioning performance and has the capability of idling with the air conditioning engaged for extended periods in very high ambient temperatures. Also, the electric cooling system is very quiet during operation. An independent front suspension with torsion bars and a five-link rear suspension with coil springs contribute to Tahoe’s direct yet compliant ride and handling characteristics. Tahoe can be equipped with two- or four-wheel drive. StabiliTrak, GM’s electronic stability control system, is standard on vehicles equipped with the Vortec 5300 engine. StabiliTrak helps the driver maintain control in sudden maneuvers, particularly in low traction conditions, in emergency lane changes and during avoidance maneuvers. StabiliTrak assists the vehicle in maintaining the driver’s intended path by applying a brake force at any corner of the vehicle independent of the driver’s use of the brake pedal. Interior convenience and flexibility In addition to its powerful V-8 engines, Tahoe can be reconfigured for a combination of passenger and cargo-carrying chores. Almost 105 cubic feet (2,962L) of cargo space is created when the second row seats are folded forward, creating a flat load floor. An optional third-row bench seat gives Tahoe room for up to nine passengers. Second-row seats provide easy access to the third row. The third-row rear seat has a 50/50 split-fold design to provide a variety of cargo/passenger configurations. The seats can be flipped forward and stowed for more cargo room, or individually and easily removed to create a flat load surface. Besides a high degree of versatility, every Tahoe has an extensive list of cabin comforts, such as power windows with driver express-down, power door locks, cruise control, tilt-adjustable steering wheel, multi-lingual driver information center, temperature and compass displays integrated into the rearview mirror, and deep-tint glass aft of the B-pillar. A tri-zone, manually controlled heating, ventilation and air conditioning (HVAC) system is standard, enabling the driver and front passenger to adjust the temperature to their individual comfort levels – up to a 30-degree Fahrenheit (13.9-degree Celsius) difference between the two front zones. Manual rear air conditioning is also standard. Rear electronic climate control is standard with the optional front system, providing second-row passengers with an automatically controlled temperature setting independent from the two front occupants, creating true tri-zone comfort. Available exterior mirrors feature power-tilt glass and power folding to protect them in narrow spaces; heating elements that clear frost, snow or ice; left-side electrochromatic glass that automatically dims headlight glare; puddle lights; turn-signal indicators in the glass; and a memory feature. An available power-adjustable camper mirror can be extended to a vehicle width of as much as 106 inches (2,692 mm). Power-adjustable brake and accelerator pedals are standard on LT and Z71 models, and optional on LS models. Impressive entertainment systems – from an available Bose sound system to a Panasonic DVD Passenger Entertainment System – add to Tahoe’s comforts, especially on longer journeys. These systems (except the base fleet radio) feature the next-generation Radio Data System and can interface with services such as the optional XM Satellite Radio (continental U.S. only). Available rear-seat audio controls allow second-row passengers to enjoy a separate audio source from front-seat occupants. An available Bose audio system uses a high-powered six-channel amplifier and an eight-speaker sound system with subwoofer. Safety and security Tahoe has a full complement of safety and security features, starting with dual-stage frontal air bags for supplemental protection for front-seat passengers. Dual-stage frontal air bags are designed to help reduce the risk of air bag-induced injury. When the air bag system’s control unit detects an impact, it determines whether the crash is severe enough to trigger a deployment, and whether the primary amount of inflation is sufficient. The primary stage alone will deploy in most frontal impacts requiring the supplemental protection of an air bag, while a secondary stage is designed to deploy in more severe frontal collisions. The Tahoe also has GM’s Passenger Sensing System (PSS). PSS uses the latest sensing technology to turn the front passenger air bag on or off. If the sensor system detects an unoccupied front passenger seat or the presence of a smaller occupant, the front passenger air bag is designed to automatically turn off so it would not deploy in the event of a frontal collision. A status indicator on the instrument panel alerts occupants that the passenger air bag is on or off. Even with this system, GM strongly recommends restraining child passengers in an appropriate child seat placed in the second or third row of the vehicle. Never install a rear-facing infant seat in front of an active air bag. GM also recommends that all children 12 and under ride in the rear seat when possible. Side-impact air bags for the driver and front outboard passenger are available. Other standard safety and security features include the LATCH (Lower Anchors and Tethers for CHildren) child-seat attachment system in the rear seats, and GM’s PASSlock II theft deterrent system. The LATCH system provides two lower anchors and a top tether anchor to be used to secure a child seat to the vehicle seat structure. These anchorages are designed to make it easier to properly install compatible child safety seats. Also standard are four-wheel anti-lock disc brakes with Hydroboost, a feature that provides more reserve power assist for braking under specific conditions. The system continues to provide sufficient power assist to stop the vehicle if the engine stalls or is turned off, by using power steering fluid pressure to decrease brake pedal effort. All Tahoe models come with the OnStar system, including a one-year subscription to the Safe & Sound plan. OnStar-equipped Tahoes feature OnStar dual-mode (analog-digital) equipment. OnStar’s digital equipment also includes enhanced 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 Hands-Free Calling that allows drivers to make and receive voice-activated phone calls using an externally mounted antenna for greater reception.
