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.
NOTE
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.

cause occupants to fall out in an 
accident. Do not drive with the liftgate 
open.

projectile that could hit and injure 
someone. The vehicle has a light 
weight luggage compartment cover to 
keep the contents of your luggage 
area out of sight; it will not retain 
heavy objects that are not tied down in 
an accident like a rollover. Tie down 
all heavy objects, whether luggage or 
cargo, using the tie down hooks. 
Don ’t place anything on top of the 
cover.
Not Securing Luggage and Cargo:
Not securing cargo while driving is 
dangerous as it could move or be 
crushed during sudden braking or a 
collision and cause injury. Make sure 
luggage and cargo is secured before 
driving.
Make sure the luggage compartment 
cover is firmly secured. If it is not 
firmly secured, it could unexpectedly 
disengage resulting in injury.
