Optimum use of dual-zone climate
control
Climate control system
The following contains instructions and rec-
ommendations to enable you to get the most
out of your dual-zone automatic climate con- trol.
R Activate climate control using the Ãand
¿ buttons. The indicator lamps in the
à and¿ buttons light up.
R Set the temperature to 22 †. R
Only use the "Windshield defrosting" func-
tion briefly until the windshield is clear
again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or
when in a tunnel. The windows could oth-
erwise fog up, since no fresh air is drawn
into the vehicle in air-recirculation mode.
R Use the ZONE function to adopt the tem-
perature settings on the driver's side for
the front-passenger side as well. The indi-
cator lamp in the ábutton goes out.

Operating the climate control systems127
Climate control
If the coolant temperature is over 248 ‡
(120 †), do not continue driving. The
engine will otherwise be damaged.
The coolant temperature gage is in the instru- ment cluster on the right-hand side( Y page 29).
Under normal operating conditions and with
the specified coolant level, the coolant tem-
perature may rise to 248 ‡ (120 †).
Tachometer
!
Do not drive in the overrevving range, as
this could damage the engine.
The red band in the tachometer indicates the engine's overrevving range.
The engine is limited within a range to protect
the engine when the red band is reached.
Outside temperature display
You should pay special attention to road con- ditions when temperatures are around freez-
ing point.
Bear in mind that the outside temperature
display indicates the temperature measured
and does not record the road temperature.
The outside temperature display is in the mul-
tifunction display ( Ypage 195).
Changes in the outside temperature are dis-
played after a short delay.
Speedometer with segments
The speedometer is divided into segments
only on vehicles with DISTRONIC PLUS.
The segments in the speedometer indicate
which speed range is available.
R DISTRONIC PLUS activated ( Ypage 163):
One or two segments in the set speed
range light up.
R DISTRONIC PLUS detects a vehicle in front
that is driving at a slower speed than the
stored speed: The segments between the speed of the
vehicle in front and the stored speed lightup.

Important safety notes
GWARNING
When you operate or program the garage doorwith the integrated garage door opener, per-
sons in the range of movement of the garage
door can become trapped or struck by the
garage door. There is a risk of injury.
When using the integrated garage door
opener, always make sure that nobody is
within the range of movement of the garage
door.
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.

The required distance between remote
control Aand the integrated garage door
opener depends on the garage door drive
system. Several attempts might be neces-
sary. You should test every position for at
least 25 seconds before trying another
position.
Synchronizing the rolling code
Pay attention to the "Important safety notes"
( Y page 264).
If the garage door system uses a rolling code,
you will also have to synchronize the garage

door system with the integrated garage door
opener in the rear-view mirror. To do this you
will need to use the programming button on
the door drive control panel. The program-
ming button may be positioned at different
locations depending on the manufacturer. It
is usually located on the door drive unit on thegarage ceiling.
Familiarize yourself with the garage door
drive operating instructions, e.g. under "Pro-
gramming of additional remote controls",
before carrying out the following steps.
Your vehicle must be within reach of the
garage door or gate opener drive. Make sure
that neither your vehicle nor any persons/
objects are present within the sweep of the
door or gate.
X Turn the SmartKey to position 2in the igni-
tion lock ( Ypage 135).
X Get out of the vehicle.
X Press the programming button on the door
drive unit.
Usually, you now have 30 seconds to ini-
tiate the next step.
X Get into the vehicle.
X Press previously programmed button ;,
= or? on the integrated garage door
opener until the door closes.
The rolling code synchronization is then
complete.
Notes on programming the remote con-
trol
Canadian radio frequency laws require a
"break" (or interruption) of the transmission
signals after broadcasting for a few seconds. Therefore, these signals may not last long
enough for the integrated garage door
opener. The signal is not recognized during
programming. Comparable with Canadian
law, some U.S. garage door openers also fea-
ture a "break". Proceed as follows:
R if you live in Canada
R if you have difficulties programming the
garage door opener (regardless of where
you live) when using the programmingsteps

Problems when programming
If you are experiencing problems programing
the integrated garage door opener on the
rear-view mirror, take note of the following
instructions:
R Check the transmitter frequency used by
garage door drive remote control Aand
whether it is supported. The transmitter
frequency can usually be found on the back
of the garage door drive remote control.
The integrated garage door opener is com-
patible with devices that have units which
operate in the frequency range of 280 to
433 MHz.
R Replace the batteries in garage door
remote control A. This increases the like-
lihood that garage door remote control A
will transmit a strong and precise signal to
the integrated garage door opener.
R When programming, hold remote controlA at varying distances and angles from the
button which you are programming. Try var- ious angles at a distance between 2and
12 inches (5to 30 cm) or at the same angle
but at varying distances.
R If another remote control is available for the
same garage door drive, repeat the same
programming steps with this remote con-
trol. Before performing these steps, make
sure that new batteries have been installed
in garage door drive remote control A.
R Note that some remote controls only trans-
mit for a limited amount of time (the indi-
cator lamp on the remote control goes out).
Press button Bon remote control Aagain
before transmission ends.
R Align the antenna cable of the garage door
opener unit. This can improve signal recep-tion/transmission.
Opening/closing the garage door
After it has been programmed, the integrated
garage door opener performs the function of
the garage door system remote control. Please also read the operating instructions
for the garage door system.
X Turn the SmartKey to position 2in the igni-
tion lock ( Ypage 135).
X Press button ;,= or? which you have
programmed to operate the garage door.
Garage door system with a fixed code: indi-
cator lamp :lights up green.
Garage door system with a rolling code:

The transmitter will transmit a signal as
long as the button is pressed. The trans-
mission is halted after a maximum of ten
seconds and indicator lamp :lights up
yellow.
X Press button ;,= or? again if neces-
sary.
Clearing the memory
Make sure that you clear the memory of the
integrated garage door opener before selling
the vehicle.
X Turn the SmartKey to position 2in the igni-
tion lock ( Ypage 135).
X Press and hold buttons ;and ?.
The indicator lamp initially lights up yellow
and then green.
X Release buttons ;and ?.
The memory of the integrated garage door
opener in the rear-view mirror is cleared.
