Safety switchYou can use the safety switch (arrow) to
deactivate the rear window switches
(when children are riding in the rear
seats, for instance).
Press the safety switch whenever
children are riding in the rear of
the vehicle. Careless use of the power
windows can lead to injury.< 380us055
Break-resistant security glassThe glass installed on all side windows
and the rear window is designed to of-
fer resistance to breakage and vandal-
ism. Each break-resistant window con-
tains several layers of clear synthetic
plastic film sandwiched between the in-
ner and outer glass panes. In addition,
another film is applied to the inner sur-
face of the glass (facing the passenger
compartment). This film prevents the
glass, if shattered, from spreading into
the passenger compartment.
Please note the following precautions
regarding this inner glass surface film:
1 The film is not scratch-resistant.
Avoid contact with sharp objects
which may break through or cut the
film
2 Clean the glass with water. If ineffec-
tive, you may use regular household
window cleaner; wipe the cleaner off
immediately.
Do not use window cleaners contain-
ing solvents or abrasives, as these
may scratch the film3 Do not apply any self-adhesive la-
bels, or labels with tape to the inner
surface
4 Do not apply window tint film to the
inner window surface
5 If frost or ice builds up on the inner
surface in cold, high-humidity cli-
mates, do not use a scraper or an
"ice-removing spray." Start the en-
gine and refer to the instructions on
defrosting the door windows.

Automatic climate controlTips for pleasant drivingUse the automatic system, i.e., press
AUTO button 4. Select an interior tem-
perature that is comfortable for you -
we recommend 707 (226) as a com-
fortable setting. When the outside tem-
perature is above 427 (56), you can
also use the air conditioning system 14.
This will dry the air and prevent window
fogging, for example if people are wear-
ing damp clothes in the vehicle. Set the
outlets 2 so that the air flows past you
and does not flow directly at you. Set
the rotary dial between the air outlets 2
for the upper body to a medium posi-
tion, since air that is somewhat cooler
promotes driving without fatigue.
The following description will guide you
through additional individual settings.
You can make the settings of your
vehicle in such a manner that,
when you unlock the car with your per-
sonalized remote control, your own per-
sonalized setting of the automatic cli-
mate control is initiated.<
Automatic air distribution
The AUTO program as-
sumes the adjustment of
the air distribution and the air supply for
you and in addition adapts the tempera-
ture to external influences (summer,
winter) to meet preferences you can
specify. This program maintains a com-
fortable in-car climate regardless of the
season. Select an interior temperature
that is comfortable for you - we recom-
mend 707 (226) as a comfortable
setting.
The temperature setting and the word
"AUTO" for the air flow appear in the
display 7 (refer to the overview on
page 100). Open the ventilation outlet
for the upper body area. Switch on the
air conditioner in warm weather. The
maximum cooling capacity is achieved
when you set the rotary dial 3 (refer to
page 104) to cold.
Individual air distribution
You can cancel the AUTO
program by selecting spe-
cific distribution patterns to
suit your own individual re-
quirements. You can direct
air to flow onto the windows , toward
the upper body , and into the footwell
.
To defrost windshield and door
windows
This program quickly removes
ice and condensation from the
windshield and the side windows.
Air conditioner
The air is cooled and dehumidi-
fied and - depending on the tem-
perature setting - warmed again when
the air conditioner system is switched
on.
Depending on the weather, the wind-
shield may fog over briefly when the en-
gine is started.
At outside temperatures below approx.
427 (56), switch off the air condi-
tioner. This will help to prevent the win-
dows from fogging up.
If the windows fog over immediately af-
ter the air conditioner is switched off,
switch it back on.
Condensation forms in the air con-
ditioner system during operation,
which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<

Automatic climate controlAutomatic recirculated-air control
(AUC)
You can respond to unpleasant
external odors by temporarily
stopping the flow of outside air. The
system then recirculates the air cur-
rently within the vehicle. Press the but-
ton repeatedly to run through the fol-
lowing control sequence:
>Indicator lamps off: Fresh air flows
into the vehicle
>Left-hand indicator lamp on – AUC
mode: The system detects pollutants
in the outside air and responds by
deactivating the outside air flow when
required. The system then recircu-
lates the air currently within the vehi-
cle
>Right-hand indicator lamp on: The
flow of external air into the vehicle is
permanently blocked. The system
then recirculates the air currently
within the vehicle.
If you have a multi-function steering
wheel with the AUC button (refer to
page 23), you can also switch between
"OFF" and AUC from there.
If the windows fog over in the re-
circulated-air mode, switch this
mode off and increase the air supply as
required.<
Rear window defroster
When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically.
Temperature
You can make individual
temperature settings on the
driver's side and the front passenger
side. Your settings will be shown in the
display 7. The displayed temperatures
are reference values for the interior
temperature. We recommend 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 tem-
perature is achieved as quickly as pos-
sible. It then maintains this tempera-
ture, regardless of the season.
You can set uncontrolled heater
output at up to 907 (326). Full
cooling output is available from the air
conditioner down to 607 (166).<

Air supply
In the "AUTO" program, the
air flow is controlled auto-
matically. AUTO will appear in the dis-
play, refer to the overview on page 100.
Use "+" and "–" to vary the air flow.
When your setting is displayed by bars,
the automatic air flow is switched off.
Automatic air distribution maintains its
setting. You can reactivate the auto-
matic air flow by pressing the "AUTO"
button.
When you press "– " during operation at
minimum blower speed all displays are
canceled: The fan, heating and air con-
ditioner are switched off. The outside
air supply is closed. By pressing any
button of the automatic climate control
(except the "REST" button 9), you can
switch the system back on.

Automatic climate controlResidual heat mode
The heat which is stored in
the engine is utilized for
heating of the interior when the engine
has been switched off (while waiting at
a railroad crossing, for instance).
In ignition key position 1, you can alter
the settings of the automatic climate
control. In ignition key position 0, the
system automatically directs heated air
to the windshield, side windows and
footwells.
This function may be activated
when the outside temperature is
below approx. 597 (156), the engine
is at operating temperature, and the
battery is adequately charged.<
Draft-free ventilationYou can adjust the vent outlets for the
upper body area for individual selection
of air-flow rates and directions:
You can open and close the ventilation
outlets with infinitely-variable adjust-
ments and direct them up or down with
the rotary dials 1. In the closed position,
air exits only at the upper center of the
instrument panel. You can use rotary di-
als 2 to adjust the flow direction from
side to side.
Set the outlets so that the air flows past
you and is not directed straight at you.380de051
Rotary dial 3 allows you to temper the
air flow from these outlets by adding
heat or cooling as desired:
>Turn toward blue – colder
>Turn toward red – warmer
To adjust the rear compartment vents:
Use the rotary dial on the left to close or
open the vent for any desired air flow.
You can adjust the temperature with the
right rotary dial in the same manner as
the adjustment for the front ventilation
outlets.
Use the levers at the centers of the vent
outlets to control the direction of the
emerging air.

Use the strap to extract the blinds, then
suspend them in the attachment pro-
vided.380de624
This system uses the automatic climate
control system blower to ventilate the
passenger compartment and reduce in-
terior temperatures while the vehicle is
parked.
The independent ventilation system is
operated via the Multi-Information Dis-
play (MID) or the onboard computer.
Refer to the separate Owner's Manual.
You can preselect the activation time
for a 30-minute ventilation cycle, or you
can switch the system on and off manu-
ally with the ignition key at position 1.
Since the system uses a substantial
amount of electrical current, you should
refrain from activating it twice in suc-
cession without allowing the battery to
be recharged in normal operation be-
tween 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 operate.
