Do not place an object such as a cushion
between the seatback and your back:
Putting an object such as a cushion
between the seatback and your back is
dangerous because you will be unable to
maintain a safe driving posture and the
seat belt cannot function at its full capacity
in a collision, which could result in a serious
accident, injury or death.
Do not place objects under the seat:
The object could get stuck and cause the
seat to not be fixed securely, and result in
an accident.
Do not stack cargo higher than the
seatbacks:
Stacking luggage or other cargo higher
than the seatbacks is dangerous. During
sudden braking or a collision, objects can
fly around and become projectiles that
may hit and injure passengers.
Make sure luggage and cargo is secured
before driving:
Not securing cargo while driving is
dangerous as it could move or be crushed
during sudden braking or a collision and
cause injury.Never allow a passenger to sit or stand on
the folded seatback while the vehicle is
moving:
Driving with a passenger on the folded
seatback is dangerous. Allowing a child to
sit up on the folded seatback while the
vehicle is moving is particularly dangerous.
In a sudden stop or even a minor collision,
a child not in a proper seat or
child-restraint system and seat belt could
be thrown forward, back or even out of the
vehicle resulting in serious injuries or death.
The child in the baggage area could be
thrown into other occupants and cause
serious injury.
Never give the car keys to children and do
not allow them to play in the vehicle (4–
Door):
Playing with the folding rear seats is
dangerous. Once the seatbacks are back
up, a child in the trunk would not be able to
get out the way they had entered. If you
have small children, keep the seatbacks
locked.
Always leave your car locked and keep the
car keys safely away from children (4–
Door):
Leaving your car unlocked or the keys in
reach of children is dangerous. Children
who find their way into the trunk through
an unlocked rear seatback or an open
trunk can become accidentally locked in
the trunk. This could result in death or
brain damage from heat prostration,
particularly in the summer. Always lock the
doors and the trunk, and as an added
measure, keep the rear seatbacks locked,
whether you have children in your home or
not.
