Risk of accident
Parktronic and Active parking assist are
merely parking aids and may not detect all
obstacles. They do not relieve you of the
responsibility of paying attention.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
manoeuvring. You could otherwise endan-
ger yourself and others.
X Stop the vehicle when the parking space
symbol shows the desired parking space in
the instrument cluster.
X Vehicles with manual transmission: Shift to
reverse gear.
Vehicles with AUTOTRONIC*: move the
selector lever to position R.

Risk of accident
When parking, you need to make sure that
no obstacles are located in the vicinity of
the vehicle during the entire operation.
Active parking assist does not relieve you
of the responsibility of paying attention. It
merely aids you by intervening actively in
the steering.
To stop the vehicle or avoid an accident you
need to apply the brakes yourself.
X Let go of the multi-function steering wheel.
X Reverse the car, being ready to brake at all
times. When reversing, do not exceed a
speed of approx.10 km/h, otherwise active
parking assist will be deactivated. Controls

Notes and recommendations on optimum
air conditioning:
R Activate the air conditioning using
the U andœ buttons. The indica-
tor lamps on the Uandœ buttons
light up.
R Set the temperature to 22 †.
R Only use the "demisting" function until
the windscreen is clear again.
R Only use the "air-recirculation mode"
briefly, e.g. when there are unpleasant
outside odours or when in a tunnel. Oth-
erwise, the windows could mist up due
to a lack of fresh air in air-recirculation
mode.
R You can use the residual heat to heat or
ventilate the vehicle interior after you
have switched off the ignition. Switching the air conditioning on/off
i When the air conditioning is switched off,
the air supply and air circulation are also
switched off. Only select this setting briefly,
otherwise the windows may mist up.

Air conditioning
135Switching cooling with air dehumidi-
fication on/off
The "cooling with dehumidification" function
is only available when the engine is running.
The air inside the vehicle is cooled and dehu-
midified according to the temperature selec-
ted. This prevents the windows from misting
up. G
Risk of accident
If the "cooling with air dehumidification"
function is deactivated, the air inside the
vehicle will not be cooled (during warm
weather) or dehumidified. The windows
could mist up more quickly. This may pre-
vent you from observing the traffic condi-
tions, thereby causing an accident. H
Environmental note
The cooling system uses the refrigerant
R134A. This refrigerant does not damage
the earth's ozone layer.
Condensation may drip from the underside of
the vehicle when Thermatic is in cooling
mode.
The "cooling with air dehumidification" func-
tion is only available with air conditioning* or
Thermotronic*. X
To switch on: press theœbutton.
The indicator lamp in the œbutton lights

X To deactivate: press theœbutton.
The indicator lamp in the œbutton goes

function has a delayed switch-off feature. Controlling the air conditioning auto-
matically
Only Thermotronic* features the "control air
conditioning automatically" function.
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 air conditioning will achieve
optimal operation if "cooling with air dehu-
midification" is also activated. If necessary,
cooling with air dehumidification can be deac-
tivated. X

G
Risk of injury
Very hot or very cold air can flow from the
air vents. This could cause burns or frost-
bite to bare skin in the immediate vicinity
of the vents. Keep bare skin away from
these air outlets. If necessary, direct the
airflow away to a different area of the vehi-
cle interior.
Please observe the following notes to ensure
that the air can flow freely through the air
vents:
R keep the air inlet between the windscreen
and the bonnet free of deposits, such as ice, snow and foliage, to guarantee the sup-
ply of fresh air into the vehicle interior.
R never cover the vents or air inlet and outlet
grilles in the vehicle interior.
i Position the sliders for the centre air
vents in the central detent position for vir-
tually draught-free ventilation.
