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 not 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
65°F (18°C) and 85°F (29°C). This forces
fresh outside air into your vehicle.
Open all air ducts on the instrument panel.
Do not use the trunk lid tie down if you are
towing a trailer because of the danger of CO.Your vehicle may be equipped with a trunk-lid tie down.
This feature is used to secure the trunk lid if it will
not close completely, such as when carrying large
packages in the trunk. Use the following steps to secure
the trunk lid:
1. Attach the clip end of the tie down to the D ring on
the trunk lid (A).
2. Attach the hook end of the tie down to the striker
located at the center of the trunk sill (B).
3. Tighten the tie down by pulling the free end of the
cord until secure.
4. To remove the tie down, press the clip end release
and loosen the cord.

A (OFF):This is the only position in which you can
insert or remove the key. This position locks the ignition
and transaxle. It is 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. 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.

Sunroof
Your vehicle may have a sunroof. The switches that
operate the sunroof are located on the overhead
console. The sunroof will only operate when the ignition
is on, or in accessory, or while Retained Accessory
Power (RAP) is active. SeeRetained Accessory Power
(RAP) on page 2-25.
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 closedposition, 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 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. SeeRetained
Accessory Power (RAP) on page 2-25.

Care of the CD Player
The use of CD lens cleaners for CD players is not
advised, due to the risk of contaminating the lens of the
CD optics with lubricants internal to the CD mechanism.
Diversity Antenna System
The AM-FM antennas are located in the windshield and
rear window. Make sure that the inside surfaces of
the windshield and rear window are not scratched and
that the grid 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
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 pick up
stations clearly. The repairs wouldn’t be covered by
your warranty.
If static is heard on the radio, when the rear window
defogger is turned on, it could mean that a defogger grid
line has been damaged. If this is true, the grid line
must be repaired.
If adding an aftermarket cellular telephone to your
vehicle, and the antenna needs to be attached to the
glass, make sure that the grid lines for the AM-FM
antennas are not damaged. Make sure the cellular
telephone antenna does not touch a grid line.
XM™ Satellite Radio Antenna
System
The XM™ 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.
