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

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.

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 aꢀect the liftgate

operation.

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
