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 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 the
moonroof, 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, or
become trapped by climbing into the
trunk, 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.
qLocking, Unlocking with Key
The driver's door can be locked/unlocked
with the key.
Turn the key toward the front to lock,
toward the back to unlock.

secured before driving: Not securing cargo while driving is
dangerous as it could move or be
crushed during sudden braking or a
collision and cause injury.
