Caution: It can be dangerous to drive with the liftgate or liftglass 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 or liftglass:

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

To unlock the liftgate, press the unlock button on the Remote Keyless Entry (RKE) transmitter twice or use the power door lock switch.

To lock the liftgate, press the lock button on the RKE transmitter or use the power door lock switch. The liftgate does not have a key lock cylinder.

To open the liftgate, press the touchpad centered on the underside of the liftgate handle and pull up.

When closing the liftgate, use the molded handles to pull the liftgate down. Push the liftgate closed until it latches.
