GM Service Manual Online
For 1990-2009 cars only

Notice: Leaving the retractable hardtop down and exposing the interior of the vehicle to outdoor conditions may cause damage. Always close the retractable hardtop if leaving the vehicle outdoors.

  1. Park on a level surface and shift the transmission into PARK (P).
  2. The vehicle's engine must be on or in ACC.
  3. Lower both sun visors.
  4. Notice: Raising or lowering the top while the vehicle is in motion can cause damage to the top or top mechanism. Make sure the vehicle is in P (Park) to lower or raise the top.

    Notice: Lowering the top if it is damp, wet, or dirty can cause stains, mildew, and damage to the inside of your vehicle. Dry off the top before lowering it.

    Notice: If you lower the retractable hardtop in cold weather (0°F/-18°C or lower), you may damage top components. Do not lower the retractable hardtop in cold weather.

  5. Make sure that nothing or no one is on or around the top. Make sure the trunk cargo cover is in place with nothing on top or in front of the cargo cover. See Rear Storage Area for more information. Also, make sure the valet lockout switch is off.

  7. Push and hold the bottom of the retractable hardtop button located on the console behind the shifter lever. The windows will automatically lower and the top will automatically lower into the storage area. A chime will sound when the top has lowered completely.

If the radio is on, the sound may be muted briefly while the retracable top is lowered. This occurs because a new audio system equalization is being loaded.

Under certain conditions, the Driver Information Center (DIC) may display a message regarding the retractable hardtop. If this happens, see DIC Warnings and Messages for more information.
