GM Service Manual Online
For 1990-2009 cars only

Caution: Exhaust gases can enter the vehicle if it is driven with the liftgate, trunk/hatch open, or with any objects that pass through the seal between the body and the trunk/hatch or liftgate. Engine exhaust contains Carbon Monoxide (CO) which cannot be seen or smelled. It can cause unconsciousness and even death.

If the vehicle must be driven with the liftgate, or trunk/hatch open:

   • Close all of the windows.
   • Fully open the air outlets on or under the instrument panel.
   • Adjust the Climate Control system to a setting that brings in only outside air and set the fan speed to the highest setting. See Climate Control System in the Index.
   • If the vehicle is equipped with a power liftgate, disable the power liftgate function.
For more information about carbon monoxide, see Engine Exhaust.

Emergency Trunk Release Handle


Object Number: 808272  Size: B3

Notice: Do not use the emergency trunk release handle as a tie-down or anchor point when securing items in the trunk as it could damage the handle. The emergency trunk release handle is only intended to aid a person trapped in a latched trunk, enabling them to open the trunk from the inside.

There is a glow-in-the-dark emergency trunk release handle located near the trunk latch. This handle will glow following exposure to light. Pull the release handle up to open the trunk from the inside.
