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.

Closing the trunk
Closing the trunk from the inside
automatically*
In vehicles with trunk opening/closing sys-
tem* you can close the trunk from the in-
side using the remote trunk closing*
switch.
Press the remote trunk closing*
switch2 (
page 112) until the indi-
cator lamp in the switch goes out and
the trunk lid is closed.
To interrupt the closing procedure:
Release remote trunk closing*
switch2.If the trunk lid comes into contact with an
object while closing (e.g. luggage that has
been piled too high), in the sequence, the
upper motion the closing procedure is
stopped and the trunk reopens slightly.iYou can also close the trunk by hand
(page 114).
Warning!
G
Maintain sight of trunk area while operating
the door mounted remote trunk closing*
switch. Monitor the closing procedure care-
fully to ensure that no one is in danger of be-
ing injured.
To interrupt the closing procedure, release
the door mounted remote trunk closing
switch.
Even with the SmartKey or the SmartKey
with KEYLESS-GO* removed from the start-
er switch or the SmartKey with
KEYLESS-GO* removed from the vehicle,
the remote trunk opening/closing* switch
can be operated. Therefore, do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Unsuper-
vised use of vehicle equipment may cause
an accident and/or serious personal injury.
Warning!
G
Only drive with the trunk closed as, among
other dangers such as blocked visibility,
exhaust fumes may enter the vehicle
interior.

Be especially careful when small children
are around. To stop the closing procedure,
do one of the following:
press trunk closing switch1
press the Š button on the SmartKey
press the remote trunk opening or clos-
ing switch (on driver’s door)
Even with the SmartKey removed from the

trunk. You may lock yourself out.iIf the vehicle was previously centrally
locked, the trunk will lock automatical-
ly after closing it (

signal lamps flash three times, and an
acoustic signal sounds three times (if
equipped and feature activated), to
confirm locking.

Locking and unlocking from the inside
You can lock or unlock the doors and the
trunk from inside using the central locking
or unlocking switch. This can be useful, for
example, if you want to lock the vehicle
before starting to drive.
You cannot lock or unlock the fuel filler flap
with the central locking or unlocking
switch.
The switches are located in the center

from the inside.
288 Controls in detailUseful featuresProgramming the integrated remote
control
Step 1:
Switch on the ignition (
page 36).
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 the 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 be-
gin directly with step 3.
Step 3:
Hold the end of the hand-held remote
control5 of the device you wish to
train approximately 2 to 5 in
(5 to12 cm) away from the signal trans-
mitter button (2, 3 or4) to be pro-
grammed, while keeping the indicator
lamp1 in view.
Step 4:
Using both hands, simultaneously
press the 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.
The indicator lamp1 will flash, first
slowly and then rapidly.
Step 5:
After the indicator lamp1 changes
from a slow to a rapidly flashing light,
release the hand-held remote control
button and the signal transmitter but-
ton.
Step 6:
Press and hold the just-trained signal
transmitter button (2, 3 or4) and
observe the indicator lamp1.
When programming a garage door opener,
park the vehicle 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.
iThe indicator lamp1 flashes immedi-
ately the first time the signal transmit-
ter button is programmed. If this button
has already been programmed, the in-
dicator lamp will only start flashing af-
ter 20 seconds.
290 Controls in detailUseful featuresStep 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 successful-
ly 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 se-
quence on the hand-held remote con-
trol until the frequency signal has been
learned. Upon successful training, the
indicator lamp1 will flash slowly and
then rapidly after several seconds.
Proceed with programming step 5 and
step 6 to complete.Reprogramming a single signal trans-
mitter button
To program a device using a signal trans-
mitter button previously trained, follow
these steps:
Switch on the ignition (
page 36).
Press and hold the desired signal
transmitter button (2, 3 or4).
Do not release the button.iUpon completion of programming the
integrated remote control, make sure
you retain the hand-held remote con-
trol that came with the garage door
opener, gate operator or other device.
You may need it for use in other vehi-
cles, for future programming of an
integrated remote control, or simply for
continued use as a hand-held remote
control to operate the respective
device in other situations.
