due to battery discharge or other
reasons, you can unlock the trunk
inside the vehicle.
Open the cable cover (1) under the
rear seat with a mechanical key and
pull the cable (2) for unlocking the
trunk. The cable is fixed firmly so it
may hard to pull. Therefore, please
put auxiliary equipment such as a
screwdriver to the loop and pull it
comfortably. You and your passengers must be
aware of the location of the emer-
gency trunk safety release lever in
this vehicle and how to open the
trunk in case you are accidentally
locked in the trunk.

cies only.
WARNING
NEVER allow anyone to occupy
the trunk of the vehicle at any
time. If the trunk is partially or
totally latched and the person is
unable to get out, serious injury
or death could occur due to lack
of ventilation, exhaust fumes
and rapid heat build-up, or
because of exposure to cold
weather conditions. The trunk is
also a highly dangerous loca-
tion in the event of a crash
because it is not a protected
occupant space but is a part of
the vehicle’s crush zone.
