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.

Do not run the engine when inside an
enclosed area:
Running the engine inside an enclosed
area, such as a garage, is dangerous.
Exhaust gas, which contains poisonous
carbon monoxide, could easily enter
the cabin. Loss of consciousness or
even death could occur.
Open the windows or adjust the
heating or cooling system to draw
fresh air when idling the engine:
Exhaust gas is dangerous. When the
vehicle is stopped with the windows
closed and the engine running for a
long time even in an open area,
exhaust gas, which contains poisonous
carbon monoxide, could enter the
cabin. Loss of consciousness or even
death could occur.
Clear snow from underneath and
around your vehicle, particularly the
tail pipe, before starting the engine:
Running the engine when a vehicle is
stopped in deep snow is dangerous.
The exhaust pipe could be blocked by
the snow, allowing exhaust gas to
enter the cabin. Because exhaust gas
contains poisonous carbon monoxide,
it could cause loss of consciousness or
even death to occupants in the cabin.Fuel-Filler Lid and Cap
▼Fuel-Filler Lid and Cap
WARNING
When removing the fuel-
filler cap,
loosen the cap slightly and wait for
any hissing to stop, then remove it:
Fuel spray is dangerous. Fuel can burn
skin and eyes and cause illness if
ingested. Fuel spray is released when
there is pressure in the fuel tank and
the fuel- filler cap is removed too
quickly.
Before refueling, stop the engine, and
always keep sparks and flames away
from the filler neck:
Fuel vapor is dangerous. It could be
ignited by sparks or flames causing
serious burns and injuries.
Additionally, use of the incorrect
fuel- filler cap or not using a fuel- filler
cap may result in a fuel leak, which
could result in serious burns or death
in an accident.
Do not continue refueling after the
fuel pump nozzle shuts off
automatically:
Continuing to add fuel after the fuel
pump nozzle has shut o ff automatically
is dangerous because overfilling the
fuel tank may cause fuel over flow or
leakage. Fuel over flow and leakage
could damage the vehicle and if the
fuel ignites it could cause a fire and
explosion resulting in serious injury or
death.
