Liftgate Hatchback

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.

To open the liftgate on a hatchback from outside of the vehicle, insert the key into the lock cylinder and turn it counterclockwise or use the RKE transmitter, if equipped. Then pull up the handle above the license plate to open the liftgate.

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

To lock the liftgate, insert the key into the lock cylinder and turn it clockwise or use the RKE transmitter, if equipped.

The liftgate can also be locked or unlocked by the central door unlocking system or RKE transmitter, if equipped. See Central Door Unlocking System and Remote Keyless Entry (RKE) System Operation.
