WARNING
Always take all children and pets with
you or leave a responsible person
with them:
Leaving a child or a pet 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.
Do not leave the key in your vehicle
with children and keep them in a
place where your children will not
find or play with them:
Leaving children in a vehicle with the
key is dangerous. This could result in
someone being badly injured or even
killed.
Keep all doors locked when driving:
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.
Always close all the windows and
panorama sunroof, lock the doors,
fuel-filler lid, and liftgate and take the
key with you when leaving your
vehicle unattended:
Leaving your vehicle unlocked is
dangerous as children could lock
themselves in a hot vehicle, which
could result in death. Also, a vehicle
left unlocked becomes an easy target
for thieves and intruders.
After closing the doors and the
liftgate, always verify that they are
securely closed:
Doors and the liftgate not securely
closed are dangerous, if the vehicle is
driven with a door and the liftgate not
securely closed, the door and the
liftgate could open unexpectedly
resulting in an accident.
Always confirm the safety around the
vehicle before opening a door and the
liftgate:
Suddenly opening a door and the
liftgate is dangerous. A passing vehicle
or a pedestrian could be hit and cause
an accident.
CAUTION

Always confirm the conditions
around the vehicle before opening/
closing the doors and the liftgate and
use caution during strong winds or
when parked on an incline. Not
being aware of the conditions
around the vehicle is dangerous
because fingers could get caught in
the door and the liftgate or a passing
pedestrian could be hit, resulting in
an unexpected accident or injury.
NOTE
Always stop the engine and lock the
doors. In addition, to prevent theft of
valuables, do not leave them inside
the cabin.
If the key is left in the following areas
and you leave the vehicle, the doors
may be locked depending on the
radio wave conditions even if the key
is left in the vehicle.

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.
Additionally, if the air bags deploy, the
cargo may scatter which could result in
serious injury or death.
