Buick Park Avenue Owner’s Service Manual

Buick Park Avenue is the flagship of the Buick line. It is both a clear articulation and a moving celebration of what Buick thinks a luxury car should be. The styling quietly makes a strong statement. It is a clean design sculpted with elegant lines, chrome touches that never look brash, and accents on the front and rear fascias that glisten like jewels. The interior is luxurious without being pretentious. Thick carpet and fine leather set off the rich look of maple or walnut.

Park Avenue is every bit as impressive when put into motion. The power of an available supercharged engine nudges the driver more deeply into the elegant seat. The refined suspension finds the ideal balance of control and comfort. Everywhere there is evidence of attention to detail. If all this care and craftsmanship agrees with your definition of a luxury car, Park Avenue is waiting.

Supercharging compacts air – making it denser, with more oxygen per cubic inch. Denser air can atomize more fuel. So, when the supercharger forces a dense fuel/air mixture into an engine’s combustion chamber, and a spark plug lights it off, the result is a bigger explosion, and more power.

The 90 cu. in. Eaton® supercharger helps the 3800 V6 deliver the kind of horsepower and torque figures often associated with a V8: 240 hp, 280 lb-ft torque. Coupled with its four-speed automatic transmission, it generates power in a linear fashion with instant, lag-free response from the supercharger.

Even without a supercharger, the 3800 has much to offer. It was named one of “The 10 Best Engines of the 20th Century” by Ward’s AutoWorld magazine.* It’s a benchmark for pushrodactuated, overhead valve V6 engines. It excels in packaging efficiency, smoothness and reliability. And, measured by output, efficiency and emissions, it equals or bests many overhead cam engines while delivering superb lowspeed power and response. Its overhead valve design assures impressive low rpm power and torque 205 hp, 230 lb-ft torque to be specific.

One of Park Avenue’s most dramatic demonstrations of intelligence is its available chassis stability control system, StabiliTrak. Here, data from Park Avenue’s sensors is tracked, evaluated and acted upon to help the car stay on its intended course. Using yaw sensors, lateral accelerometers, steering-wheel angle sensors, and wheel-speed sensors, StabiliTrak is constantly comparing the actual path the vehicle is taking with the path in which the driver is steering.

If StabiliTrak senses that the vehicle is not properly responding to steering input, it modulates individual front brakes or reduces power or both to help the driver maintain control and continue on course. This intervention can be so subtle one may never sense it’s occurring. But, while StabiliTrak is ingenious, it cannot repeal the laws of physics.
