2007 Chevrolet Silverado 1500 Pickup Owner's Manual - Page 159

Indicator lights in the switches show the current setting. The indicator lights will come on briefly when you turn on the ignition and the last chosen setting will stay on. If the lights do not come on, you should take your vehicle to your dealer for service. An indicator light will flash while shifting. Fast flashing means the conditions are not being met to make the desired shift, typically the vehicle is going too fast, the automatic transmission is not in NEUTRAL, or the clutch pedal is not fully pressed. Slow flashing means the shift is in progress. It will stay on when the shift is completed. If for some reason the transfer case cannot make a requested shift, it will return to the last chosen setting. AUTO 4WD (Automatic Four-Wheel Drive): This setting is ideal for use when road surface traction conditions are variable. When driving your vehicle in AUTO 4WD, the front axle is engaged, but the vehicle's power is primarily sent to the rear wheels. When the vehicle's software determines a need for more traction, the system will transfer more power to the front wheels. Driving in this mode results in slightly lower fuel economy than Two-Wheel Drive High. 2 m (Two-Wheel Drive High): This setting is used for driving in most street and highway situations. Your front axle is not engaged in two-wheel drive. This setting also provides the best fuel economy. {CAUTION: Shifting the transfer case to NEUTRAL can cause your vehicle to roll even if the transmission is in PARK (P). You or someone else could be seriously injured. Be sure to set the parking brake before placing the transfer case in NEUTRAL. See Parking Brake on page 170. N (NEUTRAL): Shift the vehicle's transfer case to N (NEUTRAL) only when towing your vehicle. See Recreational Vehicle Towing on page 418 or Towing Your Vehicle on page 417 for more information. 159
