Multifunction steering wheel (MFL)The controls integrated in the multi-
function steering wheel (MFL) are pro-
vided so that you can operate a number
of accessories quickly and without be-
ing distracted from traffic conditions.
You may operate:
>Selected functions of the radio as
well as the CD and cassette modes,
>the recirculated air mode of the air
conditioner or
>the steering wheel heater
*,
>the cruise control,
>selected cellular phone functions and
>the voice recognition
*
In order to operate a system via
the MFL, the corresponding
systems must be switched on.<
The illustration shows the maximum
possible number of controls, corre-
sponding to a full range of optional
equipment. Refer to the individual
accessory manuals for more detailed
descriptions.

Mirrors
The mirror on the passenger's
side features a lens with a more
convex surface than the mirror installed
on the driver's side. When estimating
the distance between yourself and
other traffic, bear in mind that the
objects reflected in the mirror are
closer than they appear. This means
that estimations of the distance to
following traffic should not be regarded
as precise.<
Electric heatersBoth mirrors are heated automatically
with the ignition key in position 2.
Interior rearview mirrorTo reduce glare from vehicles behind
you after dark, tilt the mirror by moving
the small lever.Lighted vanity mirrorFold down the sun visor and slide the
cover panel to the side as required.
The mirror lamps operate from ignition
key position 1.Sun visorsThese can be folded down toward the
windshield or swiveled out against the
side windows.390de030
Interior rearview mirror with
automatic dimmer
*
By responding to the effects of ambient
light and the glare from following traffic,
this mirror automatically dims through
an infinitely-variable range.
The mirror automatically reverts to its
clear, undimmed setting whenever you
select "Reverse."
For proper functioning of the mirror, be
sure that the two photocells are unob-
structed and clean. One of the photo-
cells (arrow) is positioned in the mirror's
glass, while the other is slightly offset
on the opposite side of the mirror.
For an explanation of the electro-chro-
mic technology used in this mirror, refer
to page 211.390de031

Automatic climate control
*
Tips for pleasant drivingUse the automatic system, that is,
press AUTO button 6. Select an interior
temperature that is comfortable for you
– we recommend 707 (226). When
the outside temperature is above 417
(56), you can also use the air condi-
tioner 12. This will dry the air and pre-
vent the window from fogging (for ex-
ample if people are wearing damp
clothes in the vehicle). Set the outlets 2
so that the airflows past you and is not
directed straight at you. Set the rotary
dial between the outlets 2 for the upper
body to a central position. This will pro-
vide cooler air, and help to prevent fa-
tigue during the journey.
Detailed setting options are described
for you in the following section.
You can make the settings of your
vehicle in such a manner that,
when you unlock the vehicle with the
remote control of your personal key,
your own personalized setting for the
automatic climate control is initiated.<
Automatic air distribution
The AUTO program assumes
the adjustment of the air
distribution and the air supply for you
and also adapts the temperature to
external influences (summer, winter) to
meet preferences you can specify. This
program maintains a comfortable in-car
climate regardless of the season. Select
an interior temperature that is pleasant
for you – we recommend 707 (226).
The selected temperature and AUTO
for the airflow appear in the display 9.
Refer to the overview on page 114.
Open the ventilation outlets for the
upper body. Switch on the air condi-
tioner 12 in warm weather. The maxi-
mum cooling capacity is achieved when
you set the rotary dial 3 (refer to
page 118) to cold.
Individual air distribution
You can cancel the AUTO
program by selecting specific
distribution patterns to suit
your own individual require-
ments. You can direct air to flow onto
the windows , toward the upper body
and into the footwell .
Temperature
You can make individual
temperature settings on the
driver's side or the front
passenger side. Your settings will be
shown in the display 9. The displayed
temperatures are reference values for
the interior temperature. We recom-
mend 707 (226) as a comfortable
setting, whether the air conditioner is
operating or not. When you start the
vehicle, the system ensures that the
selected temperature is achieved as
quickly as possible. It then maintains
this temperature, regardless of the
season.
Set the rotary dial 3 (refer to "Draft-free
ventilation" on page 118) to a medium
position to provide somewhat cooler
air. This helps to promote driving with-
out fatigue. Make use of this means of
mixing air especially for making minor
adjustments for personal comfort.
You can set uncontrolled heater
output at up to 907 (326). Full
cooling output is available from the air
conditioner down to 607 (166).<

Steering wheel heating
*
Roller sun blind
*
Independent ventilation
*
To activate and cancel the steering
wheel heater, press the button (arrow)
with the ignition key in position 2.
The lamp within the button lights up
when the steering wheel heater is in
operation.
If you have a multifunction steering
wheel without steering wheel heating,
the button for the recirculated-air mode
is in this location (refer to page 25).390de656
To operate, press the key briefly with
the ignition key in position 1 or 2.Roller sun blinds for rear side
windows
*
Use the strap to extract the blinds, then
hook them in the attachment provided.390us718
This system allows you to ventilate the
interior and lower its temperature, using
the blower of the automatic climate
control.
The independent ventilation system is
operated via the Multi-Information Dis-
play (MID) – refer to page 94 – or the
onboard monitor. Refer to the separate
Owner's Manual.
You can set two different times for the
system to start; it will remain active for
30 minutes. You can also turn it on and
off directly. Since the system uses a
substantial amount of electrical current,
you should not activate it twice in suc-
cession without allowing the battery to
be recharged in normal operation
between use.
When a preselected activation time is
set, the independent ventilation system
is operational at outside temperatures
above 607 (166), or by direct switch
activation. It cannot be switched on
when the vehicle is moving.
The air emerges via the vent outlets for
the upper body. Therefore, the vents
must be open for the system to oper-
ate.
