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
moonroof, lock the doors and the 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.
