Problems with the "Cooling with air dehumidification" function Problem
Possible causes/consequences and P Solutions
The indicator lamp in
the Z button
flashes three times or
remains off. The "Cool-
ing with air dehumidifi-
cation" function cannot
be switched on. Cooling with air dehumidification has been deactivated due to a
malfunction. X
Visit a qualified specialist workshop.
Setting climate control to automatic
General notes The automatic function is only available in
conjunction with dual-zone automatic climate
control.
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
The automatic mode functions optimally
when the "Cooling with air dehumidification"
function is activated. If necessary, cooling
with air dehumidification can be deactivated.
If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi-
cle will not be cooled. The air inside the vehi-
cle will also not be dehumidified. The win-
dows can fog up more quickly. Therefore, only
deactivate the "Cooling with air-dehumidifi-
cation" function briefly.

Problems with the rear window defroster Problem
Possible causes/consequences and P Solutions
The rear window
defroster has deactiva-
ted prematurely or can-
not be activated. The battery has not been sufficiently charged. X
Switch off any consumers that are not required, e.g. reading
lamps, interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window
defroster can be activated again.
Switching air-recirculation mode
on/off
General notes You can deactivate the flow of fresh air if
unpleasant odors are entering the vehicle
from outside. The air already inside the vehi-
cle will then be recirculated.
If you switch on air-recirculation mode, the
windows can fog up more quickly, in particu-
lar at low temperatures. Only use air-recircu-
lation mode briefly to prevent the windows
from fogging up.
The operation of air-recirculation mode is the
same for all control panels.

Air vents
Important safety notes
G WARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbite in
the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes: R
keep the air inlet between the windshield
and the hood free of blockages, such as ice,
snow or leaves. R
never cover the air vents or air intake grilles
in the vehicle interior.
i For optimal climate control in the vehicle,
open the air vents completely and set the
adjusters to the central position. Setting the center air vents X
To open the center air vent: turn the
adjuster in one of center air vents C coun-
ter-clockwise to position H .X
To close the center air vent: turn the

Useful information
i This Operator's Manual describes all
models and all standard and optional equip-
ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and

Notes on breaking-in a new vehicle
Important safety notesThe sensor system of some driving and driv-
ing safety systems adjusts automatically
while a certain distance is being driven after
the vehicle has been delivered or after
repairs. Full system effectiveness is not
reached until the end of this teach-in proce-
dure.
New and replaced brake pads and discs only
reach their optimum braking effect after sev-
eral hundred kilometers of driving. Compen-
sate for this by applying greater force to the
brake pedal.
The first 1000 miles (1500 km)
The more you look after the engine when it is
new, the more satisfied you will be with its
performance in the future. R
You should therefore drive at varying vehi-
cle and engine speeds for the first
1000 miles (1500 km). R
Avoid heavy loads, e.g. driving at full throt-
tle, during this period. R
Change gear in good time, before the tach-
ometer needle is
