You should check your engine oil level regularly; this is an added reminder. 3800 V6 Supercharged Engine (If Equipped) Your vehicle may have a 3800 V6 Supercharged engine. The supercharger is a device which is designed to pump more air into the engine than it would normally use. This air, mixed with fuel, creates increased engine power. Since the supercharger is a pump and is driven from an engine accessory drive belt, increased pressure is available at all driving conditions. The Powertrain Control Module (PCM) works with a vacuum control to regulate the increased pressure required during specific driving conditions. When this increased pressure or boost is not desired, such as during idling and light throttle cruising, the excess air that the supercharger is pumping is routed through a bypass. All of these controls working together provide high performance character and fuel efficiency in the 3800 V6 Supercharged engine. Checking Engine Oil It's a good idea to check your engine oil every time you get fuel. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground. The engine oil dipstick handle is the yellow loop near the front of the engine. 6-13
