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.

Ignition Positions
With the key in the ignition
switch, located on the
instrument panel, you can
turn the key to four
different positions:
Notice:If your key seems stuck in OFF and you
can not turn it, be sure you are using the correct
key; if so, is it all the way in? Turn the key only with
your hand. Using a tool to force it could break the
key or the ignition switch. If none of this works, then
your vehicle needs service.
OFF:This is the only position in which you can insert
or remove the key. This position also locks the transaxle.
It’s a theft-deterrent feature.ACC (Accessory):This position lets you use things
like the radio, windshield wipers, power windows
and optional sunroof when the engine is off. Use ACC if
you must have your vehicle in motion while the engine
is off, for example, if your vehicle is being pushed
or towed.
ON:This is the position for driving.
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 Phone (If Equipped)
•Radio
•Power Windows
•Audio Steering Wheel Controls
•Sunroof (Option)
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.

Umbrella Holder
The driver’s and passenger’s front seat cushion may be
equipped with an umbrella holder. Gently slide the
umbrella into the slot located under the front portion of
the driver’s or passenger’s seat cushion.
Floor Mats
Your vehicle is equipped with rubber-backed front and
rear floor mats. Keep them clean by vacuuming and using
a spot cleaner, if necessary. Do not machine wash.
Convenience Net
Your vehicle may be equipped with a convenience net.
The net attaches to the floor of the trunk. Put small
loads, like grocery bags, behind the net. It can help keep
them from falling over during sharp turns or quick
starts and stops.
The net is not for larger, heavier loads. Store them in the
trunk as far forward as you can. When not using the net,
hook the net to the tabs securing it to the sill plate.
Sunroof
The two switches that operate the optional sunroof are
located on the overhead console and include VENT,
ROOF, open and close.
2-50

Press and hold the ROOF switch rearward to the first
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 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 “Retained
Accessory Power (RAP)” underIgnition Positions
on page 2-25.

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 film. The metallic film 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.
XM™ Satellite Radio Antenna
System (48 Contiguous US States)
Your 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.
