For 1990-2009 cars only

Caution: It can be dangerous to drive with the liftgate open because carbon monoxide (CO) gas can come into your vehicle. You cannot see or smell CO. It can cause unconsciousness and even death. If you must drive with the liftgate open or if electrical wiring or other cable connections must pass through the seal between the body and the liftgate:

   • Make sure all other windows are shut.
   • Turn the fan on your heating or cooling system to its highest speed and select the control setting that will force outside air into your vehicle. See Climate Control System .
   • If you have air outlets on or under the instrument panel, open them all the way. See Engine Exhaust .

The liftgate can be locked and unlocked from outside of the vehicle by inserting the key into the lock and turning it. The Remote Keyless Entry transmitter, if the vehicle has one, can also be used. Then pull up the handle above the license plate to open the liftgate.

When closing the liftgate, close it from the center to make sure it fully latches.
