Cigarette lighter
Switch on the ignition (page 37).1Cigarette lighter
Push in cigarette lighter1.
Cigarette lighter1 will pop out auto-
matically when hot.
Reinsert cigarette lighter1 in its
socket after use.
Warning!G
Never touch the heating element or sides of
the cigarette lighter; they are extremely hot.
Hold the knob only.
Make sure that any children traveling with
you do not injure themselves or start a fire
with the hot cigarette lighter.
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.
!The lighter socket can be used to
accommodate 12V DC electrical accessories
(up to a maximum of 85 W) designed for use with
the standard “cigarette lighter” plug type. Keep
in mind, however, that connecting accessories
to the lighter socket (for example extensive con-
necting and disconnecting, or using plugs that do
not fit properly) can damage the lighter socket.
With the socket damaged, the lighter may no
longer be able to be placed in the heating
(pushed-in) position, or the lighter may pop out
too early with the lighter not hot enough.
To help avoid damaging the cigarette lighter
socket, we recommend connecting 12V DC
electrical accessories designed for use with the
standard “cigarette lighter” plug type to the 12V
power outlets (
page 257) in your vehicle
whenever possible.

180 W.
Warning!G
Whenever you are using floormats, make
sure there is enough clearance and the
floormats are securely fastened.
Floormats should always be securely fas-
tened using eyelets4 and retainer pins5.
Before driving off, check that the floormats
are securely in place and adjust them if
necessary. A loose floormat could slip and
hinder proper functioning of the pedals.
Do not place several floormats on top of
each other as this may impair pedal move-
ment.
iTo install or remove the floormat more
easily, move the driver’s seat as far to the rear
as possible (

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.
