2008 GMC Sierra 1500 Pickup Owner's Manual - Page 101

Notice: The engine is designed to work with the electronics in your vehicle. If you add electrical parts or accessories, you could change the way the engine operates. Before adding electrical equipment, check with your dealer/retailer. If you do not, your engine might not perform properly. Any resulting damage would not be covered by your vehicle's warranty. The switch used to adjust the pedals is located on the instrument panel below the climate control system. Adjustable Throttle and Brake Pedal On vehicles with this feature, you can change the position of the throttle and brake pedals. This feature is designed for shorter drivers, since the pedals cannot move farther away from the standard position, but can move toward the driver for better pedal reach. No adjustment to the pedals can be made when the vehicle is in REVERSE (R) or while using the cruise control. Press the arrow at the bottom of the switch to move the pedals closer to your body. Press the arrow at the top of the switch to move the pedals away from your body. Before you start driving, fully press the brake pedal to confirm the adjustment is right for you. While driving, make only small adjustments. Your vehicle may have a memory function which lets pedal settings be saved and recalled. See Memory Seat, Mirrors, and Pedals on page 1-4 for more information. 2-25
