Emergency Trunk Safety Release
lever in this vehicle and how to open
the trunk in case you are accidentally
locked in the trunk.

crash because it is not a protected
occupant space but is a part of the

out of the reach of children. Parents
should teach their children about the
dangers of playing in trunks. • Use the release lever for emergencies
