WARNING
Never allow a person to ride in the
luggage compartment/trunk:
Allowing a person to ride in the
luggage compartment/trunk is
dangerous. The person in the luggage
compartment/trunk could be seriously
injured or killed during sudden braking
or a collision.
Do not drive with the liftgate/trunk
lid open:
Exhaust gas in the cabin of a vehicle is
dangerous. An open liftgate/trunk lid
in a moving vehicle will cause exhaust
gas to be drawn into the cabin. This
gas contains CO (carbon monoxide),
which is colorless, odorless, and highly
poisonous, and it can cause loss of
consciousness and death. Moreover,
an open liftgate/trunk lid could cause
occupants to fall out in an accident.
Do not stack or leave loaded luggage
unsecured in the luggage
compartment:
Otherwise, the luggage may move or
collapse, resulting in injury or an
accident. In addition, do not load
luggage higher than the seatbacks. It
may affect the side or rear field of view.
Additionally, if the air bags deploy, the
cargo may scatter which could result in
serious injury or death.
