It also tells you about reclining front seatbacks and head restraints. Manual Front Seat CAUTION: You can lose control of the vehicle if you try to adjust a manual driver's seat while the vehicle is moving. The sudden movement could startle and confuse you, or make you push a pedal when you don't want to. Adjust the driver's seat only when the vehicle is not moving. If your vehicle has a manual bucket or a split bench seat, you can adjust it with this lever located at the front of the seat. Lift the lever to unlock the seat. Using your body, slide the seat to where you want it and release the lever. Try to move the seat with your body to make sure the seat is locked into place. 1-2 Manual Cushion Tilt (If Equipped) Manual Lumbar Control (If Equipped) If your vehicle has a lumbar adjustment, the knob is located on the outboard side of the seat cushion. If your vehicle has this feature, you can raise or lower the front of the driver's or passenger's seat with this lever located at the inside edge of the seat. To raise or lower the front of the seat, move the lever up or down in a continuous motion until the cushion reaches the desired height. To increase or decrease support, turn the knob toward the front or rear of the vehicle. Operating effort can be reduced if you lean forward slightly while turning the knob. 1-3 Power Seat(s) (If Equipped) If your vehicle has a power seat, you can adjust it with these controls located on the outboard sides of the seats.

Move the reclining front seatback rearward or forward by moving the control toward the rear or the front of the vehicle. See "Reclining Seatbacks" in the Index for further information. 1-4 Power Lumbar Control (If Equipped) If your vehicle has this feature, the four-way control is located on the outboard side of the seat. Memory Seat (If Equipped) If your vehicle has this feature, the buttons used to program and recall the driver's seat and recliner position are located on the driver's door trim panel. To increase or decrease support, press and hold the front or rear of the control. Let go of the control when the lower seatback reaches the desired level of support. You can also reshape the side wing area of the lower seatback for more lateral support. To increase or decrease support, press and hold the top or bottom of the control. Let go of the control when the lower seatback reaches the desired level of support. It does not store the lumbar or back support positions. To program the memory seat, do the following: 1. Adjust the driver's seat to the desired position. 2. Then press the SET button and, within five seconds, press one of the two numbered buttons on the memory control. To recall your setting, put the vehicle in PARK (P) and press the number you chose. To program the seat position for a second driver, follow the preceding steps, but press the other number on the memory control. 1-5 Heated Front Seats (If Equipped) If your vehicle has this feature, the button used to control the driver's heated seat is located on the driver's door panel. The button used to control the passenger's heated seat is located on the passenger's door panel. Reclining Seatbacks To activate the heated seats, press the button once for the HI heat setting. Press the button again for the LO heat setting. To turn off the heated seats, press the button a third time. An indicator light will illuminate for each heat setting anytime the heated seats are operating. The ignition must be in RUN for them to operate. The heated front seats will be canceled after the ignition is turned to OFF. If you still want to use the heated front seat feature after you restart your vehicle, you will need to press the heated seat button again. To adjust the front seatback, lift the manual lever located on the outboard side of the seat. Release the lever to lock the seatback where you want it. Lift the lever again without pushing on the seatback and the seatback will go to an upright position. If your vehicle has power seats with a power recliner, see "Power Seats" in the Index for further information on how to operate the reclining seatback feature. 1-6 CAUTION: Sitting in a reclined position when your vehicle is in motion can be dangerous. Even if you buckle up, your safety belts can't do their job when you're reclined like this. The shoulder belt can't do its job. In a crash, you could go into it, receiving neck or other injuries. The lap belt can't do its job either. In a crash the belt could go up over your abdomen. The belt forces would be there, not at your pelvic bones. This could cause serious internal injuries. For proper protection when the vehicle is in motion, have the seatback upright. Then sit well back in the seat and wear your safety belt properly. But don't have a seatback reclined if your vehicle is moving. 1-7 Head Restraints On some models, the head restraints tilt forward and rearward also. The rear seat head restraints in your vehicle may be adjustable. They work the same as the front seat head restraints, except they do not tilt forward or rearward. Rear Seats 60/40 Split Bench Seat Tahoe/Yukon: The rear seat may have a 60/40 split seat which may be folded down to give you more cargo space. Suburban/Yukon XL: The second row rear seat of Suburban/Yukon XL models may have a 60/40 split seat. Either side of the rear seat may be folded down to provide more cargo space. Slide the head restraint up or down so that the top of the restraint is closest to the top of your head. This position reduces the chance of a neck injury in a crash. 1-8 Folding the Seatbacks CAUTION: If the seatback isn't locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always press rearward on the seatback to be sure it is locked. On all models with 60/40 split bench seats, you must insert the center occupant lap belt latch plate into the loop provided, on the underside of the folded forward seat cushion, before folding the rear seat back down on the driver's side. You may have to adjust the location of the latch plate on the webbing so that it reaches the loop. Stowing in this loop will reduce the chances of damaging and soiling the belt. Remember to remove the latch plate from the loop before the seat is returned to the passenger position. On Suburban/Yukon XL insert the two buckles into the retainer in the seatback, before folding the rear seat on the driver's side. The buckles will be out of the way when the seat is folded and will be available for passengers to use when the seat is returned to the passenger position. Also, make sure that nothing is under or in front of the seat and that the head restraints are completely lowered. On Tahoe/Yukon models the rear seatbacks may be equipped with rearward folding head restraints. When the seatback is being folded down, the head restraint will automatically fold rearward to allow a flat load floor for cargo or entry to the third row seat (if equipped). 1-9 To fold, pull up on the strap loop at the rear of the seat cushion. Then, pull the seat cushion up an fold it forward. After folding the seat cushion fully forward, pull the seatback forward and fold the seatback down until it is flat. If the seatback cannot fold flat because it interferes with the cushion, try moving the seat forward and/or bring the front seatback more upright. On the passenger side of the Suburban/Yukon XL models, the lever at the base of the seat must be turned rearward to release the seatback. To create a load floor release the panels from the seatback by pushing forward on the latch. Then fold the panels back to cover the rear seat footwell area. To return the seat to the passenger position on a Suburban/Yukon XL do the following: 1. Lift the floor load panels and latch them into the seatback. 2. Lift the seatback up and push rearward all the way. 3. Lower the seat cushion until it latches into position. 4. Pull forward on the seatback and up on the seat cushion to make sure the seat is securely in place. 1-10 Make sure that the buckles on the driver's side seatback are accessible to the outboard and center occupant and are not under the seat cushions.
