Trunk Release HandleYour vehicle is equipped with a trunk
release handle that provides a means
of escape for children and adults in the
event they become locked inside the
trunk.
No matter how careful adults might be
with keys and locking their cars,
parents should be aware that children
may be tempted to play around
vehicles and use the trunk as a hiding
place.
Adults are advised to familiarize
themselves with the operation and
location of the release handle so that
all children can be told about it in an
appropriate way, keeping in mind that
most vehicles don’t have such handles.
WARNING
!
Open Trunk Lid and Children:Leaving the trunk lid open or
leaving children in the vehicle
with the keys is dangerous.
Children could open the trunk lid
and climb inside resulting in
possible injury or death from heat
exposure. Close the trunk lid, lock
the rear seatbacks and do not
allow children to play inside the
vehicle.
94S060–004To open the trunk lid from the inside,
pull the illuminated ‘‘ T” shaped
handle. The handle is made of
material that will glow for hours in the
darkness of the trunk following a brief
exposure to ambient light.
