entrapment in windows or inadver-
tent door lock activation, do not
leave children, people who require
the assistance of others or pets unat-
tended in your vehicle. Additionally,

come high enough to cause a signifi-
cant risk of injury or death to people

WARNING
• Do not drive with the trunk lid open.
This could allow dangerous exhaust
gases to be drawn into the vehicle.
For additional information, see “Ex-
haust gas (carbon monoxide)”
(P. 5-4).
• Closely supervise children when they
are around cars to prevent them
from playing and becoming locked in
the trunk where they could be seri-
ously injured. Keep the car locked,
with the rear seatback and trunk lid
securely latched when not in use, and
prevent children's access to car keys.

Closely supervise children when they
are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously in-
jured. Keep the car locked, with the rear

TRUNK LID
Pre-driving checks and adjustments3-21

To open the trunk from the inside, pull the
illuminated release handle until the lock re-
leases and push up on the trunk lid. The
release handle is made of a material that
glows in the dark af ter a brief exposure to
ambient light.
The handle is located inside the trunk com-
partment on the interior of the trunk lid.
INTERIOR TRUNK ACCESS
The trunk can be accessed from the pas-
senger side of the rear seat.
1. Move the front passenger seat to themost forward position.
2. Open the access cover on the rear par- cel shelf.
3. Push down on the button on the rear parcel shelf.
4. Fold down the passenger’s side seatback.
For additional information, see “Seats”
(P. 1-2).
WARNING
• Never allow anyone to ride in the
cargo area or on the rear seat when it
is in the fold-down position. Use of
these areas by passengers without
proper restraints could result in seri-
ous injury or death in an accident or
sudden stop.
• Properly secure all cargo with ropes
or straps to help prevent it from slid-
ing or shif ting. Do not place cargo
higher than the seatbacks. In a sud-
den stop or collision, unsecured
cargo could cause personal injury.
• When returning the seatbacks to the
upright position, be certain they are
completely secured in the latched
position. If they are not completely
secured, passengers may be injured
in an accident or sudden stop.
• Closely supervise children when they
are around cars to prevent them
from playing and becoming locked in
the trunk where they could be seri-
ously injured. Keep the car locked,
with the rear seatback and trunk lid
securely latched when not in use, and
prevent children's access to car keys.

WARNING
• Do not leave children or adults who
would normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
• Closely supervise children when they
are around cars to prevent them
from playing and becoming locked in
the trunk where they could be seri-
ously injured. Keep the car locked,
with the rear seatback and trunk lid
securely latched when not in use, and
prevent children's access to car keys.
EXHAUST GAS (carbon monoxide)
WARNING
• Do not breathe exhaust gases; they
contain colorless and odorless car-
bon monoxide. Carbon monoxide is
dangerous. It can cause uncon-
sciousness or death. •
If you suspect that exhaust fumes
are entering the vehicle, drive with all
windows fully open, and have the ve-
hicle inspected immediately.
• Do not run the engine in closed
spaces such as a garage.
• Do not park the vehicle with the en-
gine running for any extended length
of time.
• Keep the rear vent windows, lif t-
gates, doors and trunk lids (if so
equipped) closed while driving, oth-
erwise exhaust gases could be
drawn into the passenger compart-
ment. If you must drive with one of
these open, follow these precau-
tions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial
to high to circulate the air.
• If electrical wiring or other cable con-
nections must pass to a trailer
through the seal on the trunk lid or
the body, follow the manufacturer's
recommendation to prevent carbon
monoxide entry into the vehicle. •
The exhaust system and body should
be inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes are entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involv- ing damage to the exhaust sys-
tem, underbody, or rear of the
vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three-way catalyst
are burned at high temperatures to help
reduce pollutants.
WARNING
• The exhaust gas and the exhaust
system are very hot. Keep people,
animals or flammable materials
away from the exhaust system
components.
