Trunk Lock Release
The trunk lock release
button is located to the left
of the steering wheel on
the instrument panel.
Press the button to open the trunk. To use this feature,
your vehicle must be in PARK (P) or NEUTRAL (N)
and the valet lockout switch must be off.
You can also press the button with the trunk symbol on
the remote keyless entry transmitter to open the
trunk. To disable this feature, see ªValet Lockout Switchº
under
Theft-Deterrent Systems on page 2-19.
Trunk Lid Tie Down
{CAUTION:
Driving with the trunk lid open can allow
dangerous CO (carbon monoxide) gas to come
into your vehicle. You can't see or smell CO.
It can cause unconsciousness and even death.
If you ever need to drive with your trunk lid
open, then:
·Make sure all windows, the rear seat
pass-through and sunroof are closed.
·Turn the fan on your heating and cooling
system to its highest speed, with the
setting on AUTO and temperature between
65ÉF (18ÉC) and 85ÉF (29ÉC). This forces
fresh outside air into your vehicle.
·Open all air ducts on the instrument panel.
Don't use the trunk lid tie down if you are
towing a trailer because of the danger of CO.
2-12

Notice:If your key seems stuck in OFF and you
can't turn it, be sure you are using the correct key;
if so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the key
hard. Turn the key only with your hand. Using a
tool to force it could break the key or the ignition
switch. If none of these works, then your vehicle
needs service.
A (OFF):This is the only position in which you can
insert or remove the key. This position locks the ignition,
steering wheel and transaxle. It's a theft-deterrent
feature.
B (ACCESSORY):This position allows you to use
things like the radio and the windshield wipers when the
engine is off. This position will allow you to turn off
the engine, but still turn the steering wheel. If your
vehicle has a column shifter, you will still be able to
move the shift lever. Use ACCESSORY if you must have
your vehicle in motion while the engine is off (for
example, if your vehicle is being pushed or towed).
C (ON):This position is for driving. If your vehicle has a
console shifter and you turn off the engine, the
transaxle will lock. If you need to shift the transaxle out
of PARK (P), the ignition key has to be in ON.
D (START):This position starts the engine.Retained Accessory Power (RAP)
The following accessories on your vehicle may be used
for up to 10 minutes after the ignition key is turned
from ON to OFF:
·Cellular Telephone
·Radio
·Power Windows
·Audio Steering Wheel Controls
·Sunroof
Power to these accessories stops after 10 minutes or if
a door is opened. If you want power for another 10
minutes, close all the doors and turn the ignition key to
ON and then back to OFF. If the cellular phone is
being used while retained accessory power is active,
the timer is suspended to avoid interruption of the call.
The timer resets to 10 minutes at the end of the call.
2-24

Sunroof
Your vehicle may have a sunroof. The two switches that
operate the sunroof are located on the overhead
console and include VENT, ROOF, open and close.
Press and hold the ROOF switch rearward to the ®rst
position to open the glass panel and sunshade. The
sunshade also can be opened or closed manually.
To close the glass panel, press and hold the ROOF
switch forward. As the sunroof reaches the closed
position, it will open slightly toward the vent position and
then drop down to the closed position to provide a
better seal.Press and release the ROOF switch rearward to the
second position to express-open the glass panel to the
comfort stop position, approximately half-way open.
The comfort stop position is designed to help reduce
noise and make the rear seat passengers more
comfortable.
The glass panel may then be fully opened by pressing
the ROOF switch again.
If you press and hold and the ROOF switch in the
express-open position for more than one second, the
express-open operation will be over-ridden and the
sunroof will stop when the switch is released.
To stop the glass panel when express opening, press
the ROOF or VENT switch forward or rearward and
release.
To vent the glass panel, press and hold the VENT
switch in the open position. The sunshade must
be opened manually when using the vent position.
To close the glass panel, press and hold the VENT
switch in the close position.
The ROOF and VENT switches work only when the
ignition is on or when RAP is active. See ªRetained
Accessory Powerº under
Ignition Positions on page 2-23.

Diversity Antenna System
Your AM-FM antennas are located in the windshield and
rear window. Be sure that the inside surfaces of the
windshield and rear window are not scratched and that
the lines on the glass are not damaged. If the inside
surfaces are damaged, they could interfere with radio
reception. Also, for proper radio reception, the antenna
connector located on the passenger's side top corner of
the windshield and the antenna connector located on the
driver's side top corner of the rear window need to be
properly attached to the buttons on the glass.
Notice:Do not apply aftermarket glass tinting with
metallic ®lm. The metallic ®lm in some tinting
materials will interfere with or distort the incoming
radio reception. Any damage caused to your
backglass antenna due to metallic tinting materials
will not be covered by your warranty.
Notice:Do not try to clear frost or other material
from the inside of the front windshield and rear
window with a razor blade or anything else that is
sharp. This may damage the rear window defogger
grid and affect your radio's ability to pickup
stations clearly. The repairs wouldn't be covered by
your warranty.If, when you turn on your rear window defogger, you
hear static on your radio station, it could mean that
a defogger grid line has been damaged. If this is true,
the grid line must be repaired.
If you choose to add an aftermarket cellular telephone
to your vehicle, and the antenna needs to be attached to
the glass, be sure that you do not damage the grid
lines for the AM-FM antennas or place the cellular
telephone antenna over the grid lines.
XMŸ Satellite Radio Antenna
System (United States Only)
Your XMŸ Satellite Radio antenna is located on the
roof of your vehicle. Keep this antenna clear of
snow and ice build up for clear radio reception.
