Midgate® (SUT) Lowering the Midgate The Midgate window must be completely lowered for the Midgate® to be lowered. See "Midgate® Window" under Power Windows on page 2-20. Both the Midgate and the Midgate window can be lowered while the ignition is in either ON/RUN or ACC/ACCESSORY, or while in Retained Accessory Power (RAP) mode. See Retained Accessory Power (RAP) on page 2-29 for more information. To lower the Midgate: 1. Fold the rear seats forward. See Split Folding Rear Seat on page 1-11. The front seats may have to be moved forward slightly. 2. { CAUTION: It can be dangerous to drive with the cargo area covered and the tailgate and the Midgate® open because carbon monoxide (CO) gas can come into your vehicle. You can not see or smell CO. It can cause unconsciousness and even death. If you must drive with the cargo covers on and the tailgate and Midgate® open or if electrical wiring or other cable connections must pass through the seal between the body and the Midgate®: • Make sure all windows are shut. • Turn the fan on your heating or cooling system to its highest speed on the setting that brings in outside air. This will force outside air into your vehicle. See Dual Automatic Climate Control System on page 3-22. • If you have air outlets on or under the instrument panel, open them all the way. See Engine Exhaust on page 2-45. The Midgate® allows you to extend the length of the vehicle's cargo area into the cab. 2-14 K (Midgate Window): Press the bottom part of this switch to lower the Midgate window. See Instrument Panel Overview on page 3-4 for the location of this switch. The window can also be operated using the global express-down button.
