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/
trunk lid 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/
trunk lid, always verify that they are
securely closed:
Doors and the liftgate/trunk lid not
securely closed are dangerous, if the vehicle
is driven with a door and the liftgate/trunk
lid not securely closed, the door and the
liftgate/trunk lid could open unexpectedly
resulting in an accident.
Always confirm the safety around the
vehicle before opening a door and the
liftgate/trunk lid:
Suddenly opening a door and the liftgate/
trunk lid 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/trunk lid 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/trunk
lid or a passing pedestrian could be hit,
resulting in an unexpected accident or
injury.
