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
fi
nd 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, 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/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 con firm 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.
