Doors and Locks
Door LocksWARNINGAlways 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 both 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 both the windows and
convertible top, lock the doors 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, always verify
that they are securely closed:
Doors not securely closed are
dangerous, if the vehicle is driven with
a door not securely closed, the door
could open unexpectedly resulting in
an accident.
Always confirm the safety around the
vehicle before opening a door:
Suddenly opening a door 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 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 or a passing
pedestrian could be hit, resulting in an
unexpected accident or injury. 
If the power window does not go up or
down automatically because the battery
is dead, slowly open/close the power
window while pressing the glass inward.
Otherwise, the power window may
contact the convertible top and the door
cannot be opened/closed resulting in
damage to the window.

Doors and Locks
*Some models.Closing the trunk lid
Use both hands to push the trunk lid down
until the lock snaps shut. Do not slam it.
Pull up on the trunk lid to make sure it is
secure.
Inside Trunk Release
Lever *
Your vehicle is equipped with an inside
trunk release lever that provides a means
of escape for children and adults in the
event they become locked inside the trunk.
No matter how careful adults might be
with keys and locking their cars, parents
should be aware that children may be
tempted to play around vehicles and use
the trunk as a hiding place.
Adults are advised to familiarize
themselves with the operation and location
of the inside trunk release lever so that
all children can be told about it in an
appropriate way, keeping in mind that
most vehicles do not have such levers.
WARNING Close the trunk lid, do not allow children
to play inside the trunk:
Leaving the trunk lid open or leaving
children in the vehicle with the keys is
dangerous. Children could open the
trunk lid and climb inside resulting
in possible injury or death from heat
exposure.
Always keep the car from being a
tempting place to play by latching the
doors and the trunk, and keeping the
keys where children can not play with
them:
Leaving children or animals
unattended in a parked vehicle is
dangerous. Babies left sleeping and
children who lock themselves in cars or
trunks can die very quickly from heat
prostration. Do not leave your children
or pets alone in a car at any time. Do
not leave the car, the trunk unlocked.
