WARNING
Unattended Children and Pets:
Leaving a child or an animal
unattended in a parked vehicle is
dangerous. In hot weather,
temperatures inside a vehicle can
become high enough to cause brain
damage or even death. Always take all
children and animals with you or
leave a responsible person with them.
Keys and Children:
Leaving children in a vehicle with the
key is dangerous. This could result in
someone being badly injured or even
killed. They could play with power
windows or other controls, or even
make the vehicle move. Don't leave the
keys in your vehicle with children and
keep them in a place where your
children will not find or play with
them.
Unlocked Doors:
Unlocked doors in a moving vehicle
are dangerous. Passengers can fall out
if a door is accidentally opened and
can more easily be thrown out in an
accident. So keep all doors locked
when driving.

Always remove the key from the
ignition switch, close all windows, and
lock all doors and the trunk lid/liftgate
when leaving your vehicle unattended.
This discourages intruders and thieves.

Inside Trunk Release Slide
Lever (4 Door)
Your vehicle is equipped with an inside
trunk release slide lever 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 inside trunk release slide
lever so that all children can be told about
it in an appropriate way, keeping in mind
that most vehicles don't have such levers.
