Rear Seats
Split Folding Rear Seat
Your vehicle may have a split folding rear seat. A split
folding rear seat allows you to carry long cargo by
folding down part or all of the rear seat. Before you can
fold the rear seatback, you need to unlatch the center
seatbelt buckle.
Use the following steps to lower one or both of the rear
seatbacks:
1. Insert a tool with a
small tip into the slot
as shown to unlatch
the seatbelt buckle.
Then move the belt
to the side so it is
not in your way.2. There is a tab located
on the outboard sides
of the seatback. Pull
forward on the tab to
unlock the seatback.
Notice:Folding a rear seat with the safety belts
still fastened may cause damage to the seat or the
safety belts. Always unbuckle the safety belts
and return them to their normal stowed position
before folding a rear seat.
3. Fold the seatback down. This will allow you direct
access to the trunk.

At times you may notice a decrease in operating range.
This is normal for any RKE system. If the transmitter
does not work or if you have to stand closer to
your vehicle for the transmitter to work, try this:
Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-5.
If you are still having trouble, see your dealer or a
qualied technician for service.
Remote Keyless Entry System

Matching Transmitter(s) to
Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can
be purchased through your dealer. Remember to bring
any remaining transmitters with you when you go to
your dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock
your vehicle. Each vehicle can have a maximum of four
transmitters matched to it.

Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot 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.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-37.
Trunk Lock Release
The remote trunk release
button is located on the
lower portion of the
driver’s door.
To use the remote trunk release, the shift lever must be
in PARK (P) or NEUTRAL (N) for a vehicle with an
automatic transmission. The shift lever must be
in NEUTRAL, with the parking brake set for a vehicle
with a manual transmission.
Press the button to open the trunk. You can also press
the button with the trunk symbol on the Remote
Keyless Entry (RKE) transmitter to open the trunk.
If your vehicle is ever without power, you can still access
the trunk area. Use one of the following procedures to
manually open the trunk.

Emergency Trunk Release Handle
Notice:Do not use the emergency trunk release
handle as a tie-down or anchor point when securing
items in the trunk as it could damage the handle.
The emergency trunk release handle is only
intended to aid a person trapped in a latched trunk,
enabling them to open the trunk from the inside.
There is a glow-in-the-dark emergency trunk release
handle located on the back wall of the trunk. This handle
will glow following exposure to light. Pull the release
handle toward the front of the vehicle to open the trunk
from the inside.
Windows
{CAUTION:
Leaving children, helpless adults, or pets in a
vehicle with the windows closed is dangerous.
They can be overcome by the extreme heat
and suffer permanent injuries or even death
from heat stroke. Never leave a child, a
helpless adult, or a pet alone in a vehicle,
especially with the windows closed in warm or
hot weather.
2-14

Sun Visors
Swing down the primary visor to block out glare. It can
also be detached from the center mount and moved
to the side to block glare from that direction.
The driver’s visor may also have buttons for a built-in
garage door opener. SeeUniversal Home Remote
System on page 2-45for more information.
Lighted Visor Vanity Mirror
Pull the visor down and lift the cover to access the
mirror. A light comes on when the cover is lifted and
goes out when it is closed.
Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Theft-Deterrent System
If your vehicle has this
feature, the security light is
located on the instrument
panel cluster.
If the ignition is off and a door is open, the security light
will ash, reminding you to arm the theft-deterrent
system.
To arm the system, do the following:
1. Lock the door using the Remote Keyless
Entry (RKE) transmitter or the power door
lock switch.
2. Close all the doors. The security light will come on.
It should go off within approximately 30 seconds.
Your security system is now armed.
If a door or a trunk is opened without a key or a RKE
transmitter, the horn will sound and the lamps will ash
for up to 30 seconds.
