Warnings and CautionsWhen Using the Doors
WARNING
Opening/closing of the doors must be
done by an adult.
If a person's hand, foot, or neck is
pinched in a door, it could result in
serious injury.
Do not drive the vehicle with the
door-ajar warning light/indication
turned on/displayed.
Otherwise, the door may open
unexpectedly and result in an accident.
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/moonroof, 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 during strong winds or
when parked on an incline before
opening/closing the doors. Neglecting
to check the conditions around the
vehicle could result in fingers getting
caught in the door or a passing
pedestrian being hi t, resulting in an
unexpected accident or injury.

Warnings and Cautionsfor Using the Liftgate
WARNING
Do not allow people to ride in the
luggage compartment.
During sudden braking or a collision,
the person in the luggage
compartment could be seriously
injured or killed.
Always drive the vehicle with the
liftgate closed.
If the liftgate opens while driving the
vehicle, the luggage may fall out and
lead to an accident. In addition, If the
vehicle is driven with the liftgate open,
the exhaust gas may penetrate the
cabin and it could cause carbon
monoxide poisoning.
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.
If the air bags deploy, the cargo may
scatter which could result in serious
injury or death.
After closing the liftgate, make sure
that it is securely closed.
Driving the vehicle with the liftgate not
fully closed is dangerous as a person or
an object could fall out of the vehicle
resulting in a serious accident, injury,
or death.
Do not drive the vehicle with the
liftgate-ajar warning indication
displayed.
Otherwise, the liftgate may open
unexpectedly and result in an accident.
CAUTION
 Remove snow or ice on the liftgate
before opening the liftgate. When
opening the liftgate, it could slam
shut by the weight of snow or ice,
resulting in injury.
 Be careful when opening/closing the
liftgate during strong winds.
Otherwise, it could close suddenly
resulting in injury.
 When opening the liftgate, fully open
it 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.
 Stop the hybrid system when loading
or unloading cargo in the luggage
compartment. 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.
