Inside Trunk ReleaseLever (4-door)
*
▼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, be sure the seat
backs are latched and do not allow
children to play inside the vehicle:
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
rear seats, 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 rear folding seats or the
trunk unlocked.
▼
Opening the Trunk Lid from the
Inside
Slide the inside trunk release lever in
the direction of the arrow. The lever is
made of material that will glow for
hours in the darkness of the trunk
following a brief exposure to ambient
light.

The inside trunk release lever is located
on the inside of the trunk lid.

The windows can be opened/closed
by operating the power window
switches.
WARNING
Make sure the opening is clear before
closing a window:
Closing a power window is dangerous.
A person's hands, head, or even neck
could be caught by the window and
result in serious injury or even death.
This warning applies especially to
children.
Never allow children to play with
power window switches:
Power window switches that are not
locked with the power window lock
switch would allow children to operate
power windows unintentionally, which
could result in serious injury if a child's
hands, head or neck becomes caught
by the window.
Make sure nothing blocks the window
just before it reaches the fully closed
position or while fully holding up the
power window switch:
Blocking the power window just before
it reaches the fully closed position or
while fully holding up the power
window switch is dangerous.
In this case, the jam-safe function may
not prevent the window from closing
all the way. If
fingers are caught,
serious injuries could occur.
Do not let a child put a hand or head
out of the window while driving the
vehicle:
If the person's hand or head hits
something outside the vehicle, or
sudden braking is applied, it could
result in serious injury or death.
NOTE
When driving with only 1 of the rear
windows open, your ears might
experience a resonating sound.
However, this does not indicate a
problem. The sound can be reduced
by slightly opening a front window or
by changing the size of the rear
window opening.
▼ Opening/Closing Windows
The window opens while the switch is
pressed and it closes while the switch
is pulled up with the ignition switched
ON. Do not open or close 3 or more
windows at the same time.
The front passenger's window and rear
windows can be opened/closed when
the power window lock switch on the
driver's door is in the unlocked
position. Keep this switch in the locked
position while children are in the
vehicle.
