Your vehicle is equipped with the emergency liftgate safety release lever located on the bottom of the liftgate. When someone is inadvertently locked in the luggage compartment, the liftgate can be opened by doing as follows:
1. Remove the cover.
2. Push the release lever to the right.
3. Push up the liftgate.
WARNING
WARNING
NEVER allow anyone to occupy the rear cargo area of the vehicle at any time. If the liftgate is partially or totally latched and the person is unable to get out, serious injury or death could occur due to lack of ventilation, exhaust fumes and rapid heat build-up, or because of exposure to cold weather conditions. The liftgate is also a highly dangerous location in the event of a crash because it is not a protected occupant space but is a part of the vehicle’s crush zone.
WARNING

Do not grasp the part supporting the liftgate (gas lifter), as this may cause serious injury.
