Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can not see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-29.
Trunk Lock
To unlock the trunk lid from the outside, insert the door
key into the trunk lock and turn it counterclockwise.
Or, with the vehicle in PARK (P), press the open trunk
symbol on the remote keyless entry transmitter.
Remote Trunk Release
Press the remote trunk
release button located
behind the glove box door
to release the trunk lid
from inside the vehicle.
The shift lever must be in PARK (P), but the key does
not have to be in the ignition for the remote trunk
lid release button to work.

Interior Lamps
Instrument Panel Brightness
The instrument panel lights can be brightened or
dimmed by turning the exterior lamps knob.
Turning the control all the way clockwise turns on the
courtesy lamps.
Courtesy Lamps
When any door is opened, several courtesy lamps come
on to make it easier to enter and exit the vehicle.
These lamps can also be turned on by turning the
exterior lamps control all the way clockwise to MAX.
Entry Lighting
The courtesy lamps will come on and stay on for a set
time whenever you press UNLOCK on the remote
keyless entry transmitter.
The lamps will stay on while a door is opened and then
turn off automatically about 25 seconds after it is
closed. If the UNLOCK button is pressed and a door is
not open, the lamps will turn off after about 40 seconds.Entry lighting includes a feature called theater dimming.
With theater dimming, the lamps do not turn off at
the end of the delay time. Instead, they slowly dim after
the delay time and then turn off.
The courtesy lamps are canceled if the ignition key is
turned to RUN or START and will not come on unless a
door is opened.
Delayed Entry Lighting
Delayed entry lighting lights the vehicle’s interior for a
period of time after all the doors have been closed.
The ignition must be off for delayed entry lighting
to work. After all the doors have been closed, the
delayed entry lighting feature will continue to work until
one of the following occurs:
The ignition is in RUN.
The doors are locked.
An illumination period of 25 seconds has elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled and the
interior lamps will remain on.
