Never allow a person to ride in the luggage
compartment:
Allowing a person to ride in the luggage
compartment is dangerous. The person in
the luggage compartment could be
seriously injured or
killed during sudden
braking or a collision.
Do not drive with the liftgate open:
Exhaust gas in the cabin of a vehicle is
dangerous. An open liftgate 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 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.
CAUTION
 Before opening the liftgate, remove any
snow and ice accumulation on it.
Otherwise, the liftgate could close under
the weight of the snow and ice resulting
in injury.

Be careful when opening/closing the
liftgate during strong winds. If a strong
gust blows against the liftgate, it could

 Fully open the liftgate and make sure
that it stays open. If the liftgate is only
opened partially, it could slam shut by
vibration or wind gusts resulting in
injury.
 When loading or unloading luggage in
the luggage compartment, turn off the
engine. Otherwise, you could get burned
by the heat of the exhaust gas.
 Be careful not to apply excessive force to
the damper stay on the liftgate such as
by putting your hand on the stay.
Otherwise, the damper stay may bend
and
affect the liftgate operation.
