Door Locks
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 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 the
fuel-filler 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 fuel-filler lid,
always verify that they are securely closed:
Doors and the fuel-filler lid not securely
closed are dangerous, if the vehicle is
driven with a door and the fuel-filler lid not
securely closed, the d oor and the fuel-filler
lid could open unexpectedly resulting in an
accident.
Always confirm the safety around the
vehicle before opening a door and the
fuel-filler lid:
Suddenly opening a door and the fuel-filler
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 fuel-filler 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 fuel-filler lid
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/roof and the
door cannot be opened/closed resulting
in damage to the window.

doors and the fuel-filler lid in the event
the vehicle is involved in an accident to
allow passengers to get out of the
vehicle immediately and prevent being
trapped inside. While the ignition is
switched ON and in the event the vehicle
receives an impact strong enough to
inflate the air bags, both the doors and
the fuel-filler lid are automatically
unlocked after about 6 seconds have
elapsed from the time of the accident.
The doors and the fuel-filler lid may not
unlock depending on how an impact is
applied, the force of the impact, and
other conditions of the accident.
If door-related systems or the battery is
malfunctioning, the doors and the
fuel-filler lid will not unlock.
When opening a door, the power
windows open a little automatically.

windows close automatically. This is a
function for improving the sealability,
and it does not mean there is a problem.

vehicle maintenance or other reasons,
the power windows will not open or
close automatically. If the power
windows do not open or close, the
automatic open/close mechanism for the
windows must be reset.
