1-3 Memory Seat (If Equipped)
If your vehicle has this
feature the controls are
located on the driver's door,
and are used to program and
recall memory settings for
the driver's seating and
outside mirror positions.
Adjust the driver's seat (including the seatback recliner
and lumbar) and both of the outside mirrors to the
desired position. Then press and hold button 1
(for driver 1) for three seconds. A double chime will
sound to let you know that the position has been stored.
A second mirror and seating position can be
programmed by repeating the procedure with a
second driver and pressing button 2 for three seconds.
Each time button 1 or 2 is pressed and released while
the vehicle is in PARK (P), a single chime will sound,
and the memory position will be recalled.If you use the unlock button on the remote keyless entry
transmitter to enter your vehicle, the preset driver's seat
and mirror positions will be recalled if programmed to
do so through the Driver Information Center (DIC).
The numbers on the back of the transmitters, 1 or 2,
correspond to the numbers on the memory controls.
The seat and mirror positions can also be recalled by
placing the key in the ignition if programmed to do
so through the Driver Information Center (DIC).
To stop recall movement of the memory feature at
any time, press one of the power seat controls or
memory buttons.
Two personalized exit positions can be set by first
recalling the driver's position (by pressing 1 or 2),
then positioning the seat in the desired exit position for
that driver. Then press and hold the button with the exit
symbol for three seconds. A double chime will sound to
let you know that the position has been stored. With the
vehicle in PARK (P), the exit position for that driver
can be recalled by pressing the exit button. The mirrors,
power lumbar and recline positions will not be stored
or recalled for the exit positions. If no exit position is
stored, the default is all the way rearward.

Programming for automatic seat and mirror movement
can be done through the Driver Information Center
(DIC). You can choose to either select or not select
automatic seat and mirror movement by using the
remote keyless entry transmitter, by placing your
key in the ignition, or when exiting the vehicle. For
programming information, see ªVehicle Programming
and Personalization Featuresº in the Index.
Heated Front Seats (Option)
Your vehicle may have
heated front seats. The
buttons used to control
this feature are located
on the front door armrests.
The engine must be running
for the heated seat feature
to work.To heat the entire seat, press the horizontal button with
the heated seat symbol. Press the button to cycle through
the temperature settings of high, medium and low, and
to turn the heated seat off. The indicator lights will glow
to designate the level of heat selected: three for high,
two for medium and one for low. The low setting warms
the seatback and cushion until the seat temperature is
near body temperature. The medium and high settings
heat the seatback and seat cushion to a slightly higher
temperature. You will be able to feel heat in about
two minutes.
To heat only the seatback, press the vertical button with
the heated seatback symbol. An indicator light on the
seatback switch will glow to designate that only the
seatback is being heated. Additional presses will cycle
through the heat levels for the seatback only. Press the
horizontal button again to heat the whole seat.
The feature will shut off automatically when the ignition
is turned off.

Door Locks
CAUTION:
Unlocked doors can be dangerous.

Passengers -- especially children -- can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle won't open it. You increase the
chance of being thrown out of the vehicle in
a crash if the doors aren't locked. So, wear
safety belts properly and lock the doors
whenever you drive.

Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.

Outsiders can easily enter through an
unlocked door when you slow down or stop
your vehicle. Locking your doors can help
prevent this from happening.
There are several ways to lock and unlock your vehicle.
You can use the remote keyless entry system.
You can use your key to unlock your door from
the outside.
You can lock or unlock the door from the inside by
sliding the manual lever forward or rearward. When the
door is unlocked, you can see a red area on the lever.
The manual lever on each rear door works only that
door's lock.

2-10
Lockout Prevention
This feature stops the power door locks from locking
when the key is in the ignition and a door is open to
protect you from locking your key in the vehicle.
If the power lock switch is pressed when a door is open
and the key is in the ignition, all the doors will lock and
then the driver's door will unlock.
Leaving Your Vehicle
If you are leaving the vehicle, take your key, open your
door and set the locks from inside. Then get out and
close the door.
Remote Keyless Entry System
With this system you can lock and unlock your doors
from about 3 feet (1 m) up to 30 feet (9 m) away
using the remote keyless entry transmitter supplied with
your vehicle.
Your remote keyless entry system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.
This device complies with RSS
-210 of Industry Canada.
Operation is subject to the following two conditions:
(1) this device may not cause interference, and (2) this
device must accept any interference received, including
interference that may cause undesired operation of
the device.

2-11
Changes or modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.
At times you may notice a decrease in range. This is
normal for any remote keyless entry 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 or
resynchronization is necessary. See the instructions
that follow.

If you're still having trouble, see your dealer or a
qualified technician for service.Operation
(Unlock): When you
press unlock, the driver's
door will unlock
automatically, the parking
lamps may flash and the
interior lights will go on.
You can program different feedback settings through the
Driver Information Center (DIC). For more information
see ªDriver Information Center (DIC)º in the Index.
(Lock): Press lock to lock all the doors. Press lock
again within three seconds and the horn will chirp.
(Panic): When the button with the horn symbol
on the key transmitter is pressed, the horn will sound
and the headlamps and taillamps will flash for up to
30 seconds. This can be turned off by pressing the horn
button again, or by waiting for 30 seconds, or by starting
the vehicle.

2-12
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.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's probably time to change the battery.
The Driver Information Center (DIC) will display a
RFA # BATTERY LOW message when the transmitter
battery is low.
NOTICE:
When replacing the battery, use care not to touch
any of the circuitry. Static from your body
transferred to these surfaces may damage
the transmitter.

2-13
To replace the battery in the remote keyless
entry transmitter:
1. Insert a thin coin in the slot between the covers
of the transmitter housing. Gently pry the
transmitter apart.
2. Remove and replace the battery with a three
-volt
CR2032 or equivalent battery, positive (+)
side down.
3. Align the covers and snap them together.
4. Check the operation of the transmitter.
Liftgate/Liftglass
CAUTION:
It can be dangerous to drive with the liftgate or
liftglass open because carbon monoxide (CO) gas
can come into your vehicle. You can't see or smell
CO. It can cause unconsciousness and even death.
If you must drive with the liftgate or liftglass
open or if electrical wiring or other cable
connections must pass through the seal between
the body and the liftgate or liftglass:

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed with the setting
on panel or bi
-level with recirculation off.
That will force outside air into your vehicle.
See ªComfort Controlsº in the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.
