Warning!G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle.
A child’s unsupervised access to a vehicle
could result in an accident and/or serious
personal injury.
!Opening a door causes the windows on that
side of the car to open slightly. They will return to
the up position when the door is closed.
The side windows will not open or close if the
battery is discharged or the windows are imped-
ed by ice. As a result, you may no longer be able
to properly close the door. Do not attempt to
force the door shut. Doing so may damage the
door or the side window. Correct the condition
that prevents the windows from operating before
attempting to close the door.

ate the equipment installed in your vehicle.
If you are already familiar with the basic
functions of your vehicle, this section will
be of particular interest to you.
To quickly familiarize yourself with the
basic functions of the vehicle, refer to the
“Getting started” section of this manual.
The corresponding page numbers are
given at the beginning of each segment.
For more information on unlocking and
locking, see (
page 36) and (page 59).
Locking and unlocking
SmartKey
Your vehicle comes supplied with two
SmartKeys, each with remote control and
a removable mechanical key.
The locking tabs for the mechanical key
portion of the two SmartKeys are a
different color to help distinguish each
SmartKey unit.
The SmartKey provides an extended oper-
ating range. To prevent theft, however, it is
advisable to only unlock the vehicle when
you are in close proximity to it.
The SmartKey centrally locks and unlocks:
the doors
the trunk
the fuel filler flap
the glove box
the storage/telephone* compartment
under the armrest

Programming the integrated remote
control
Step 1:
Switch on the ignition (page 37).Step 2:
If you have previously programmed a
signal transmitter button and wish to
retain its programming, proceed to
step 3.
If you are programming the integrated
remote control for the first time, press
and hold the two outer signal transmit-
ter buttons2 and4 and release
them only when indicator lamp1
begins to flash after approximately
20 seconds (do not hold the button for
longer than 30 seconds). This proce-
dure erases any previous settings for
all three channels and initializes the
memory.
If you later wish to program a second
and/or third hand-held transmitter to
the remaining two signal transmitter
buttons, do not repeat this step and
begin directly with step 3.Step 3:Hold the end of hand-held remote
control5 of the device you wish
to train approximately
2 to 5 in (5 to12 cm) away from the
signal transmitter button (2, 3 or4)
to be programmed, while keeping indi-
cator lamp1 in view.
Step 4:
Using both hands, simultaneously
press hand-held remote control
button6 and the desired signal trans-
mitter button (2, 3 or4). Do not
release the buttons until step 5 is com-
pleted.
Indicator lamp1 will flash, first slowly
and then rapidly.
When programming a garage door opener, it
is advised to park outside the garage.
Do not run the engine while programming
the integrated remote control. Inhalation of
exhaust gas is hazardous to your health.
All exhaust gas contains carbon monoxide
(CO), and inhaling it can cause unconscious-
ness and possible death.
iIndicator lamp1 flashes immediately the
first time the signal transmitter button is pro-
grammed. If this button has already been pro-
grammed, the indicator lamp will only start
flashing after 20 seconds.

Step 5:
After indicator lamp1 changes from a
slow to a rapidly flashing light, release
the hand-held remote control button
and the signal transmitter button.
Step 6:
Press and hold the just-trained signal
transmitter button (2, 3 or4) and
observe indicator lamp1.
If indicator lamp1 stays on
constantly, programming is complete
and your device should activate when
the respective signal transmitter
button (2, 3 or4) is pressed and
released.
Step 7:
To program the remaining two signal
transmitter buttons, repeat the steps
above starting with step 3.Rolling code programming
To train a garage door opener (or other
rolling code devices) with the rolling code
feature, follow these instructions after
completing the “Programming” portion
(steps 1 through 6) of this text. (A second
person may make the following training
procedures quicker and easier.)
Step 8:
Locate “training” button on the garage
door opener motor head unit.
Exact location and color of the button
may vary by garage door opener brand.
Depending on manufacturer, the
“training” button may also be referred
to as “learn”or “smart” button. If there
is difficulty locating the transmitting
button, refer to the garage door opener
Operator’s Manual. Step 9:
Press the “training” button on the
garage door opener motor head unit.
The “training light” is activated.
You have 30 seconds to initiate the follow-
ing step.
Step 10:
Return to the vehicle and firmly press,
hold for 2 seconds and release the
programmed signal transmitter
button (2, 3 or4).
iIf indicator lamp1 flashes rapidly for about
2 seconds and then turns to a constant light,
continue with programming steps 8 through 12
as your garage door opener may be equipped
with the “rolling code” feature.

Step 11:
Press, hold for 2 seconds and release
same signal transmitter button a
second time to complete the training
process.
Step 12:
Confirm the garage door operation by
pressing the programmed signal trans-
mitter button (2, 3 or4).
Step 13:
To program the remaining two signal
transmitter buttons, repeat the steps
above starting with step 3.Gate operator/Canadian programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission
which may not be long enough for the
integrated signal transmitter to pick up the
signal during programming. Similar to this
Canadian law, some U.S. gate operators
are designed to “time-out” in the same
manner.
If you live in Canada or if you are having
difficulties programming a gate operator
(regardless of where you live) by using the
programming procedures, replace step 4
with the following:
Step 4:Press and hold the signal transmitter
button (2, 3 or4). Do not
release this button until it has been
successfully trained.
While still holding down the signal
transmitter button (2, 3 or4),
“cycle” your hand-held remote control
button6 as follows: Press and hold
button6 for 2 seconds, then release
it for 2 seconds, and again press and
hold it for 2 seconds. Repeat this
sequence on the hand-held remote
control until the frequency signal has
been learned. Upon successful train-
ing, indicator lamp1 will flash slowly
and then rapidly after several seconds.
Proceed with programming step 5 and
step 6 to complete.
iSome garage door openers (or other rolling
code equipped devices) may require you to
press, hold for 2 seconds and release the same
signal transmitter button a third time to
complete the training process.
iUpon completion of programming the inte-
grated remote control, make sure you retain the
hand-held remote control that came with the ga-
rage door opener, gate operator or other device.
You may need it for use in other vehicles, for fu-
ture programming of an integrated remote con-
trol, or simply for continued use as a hand-held
remote control to operate the respective device
in other situations.
