Risk of accident
Parktronic is only an aid and may not detect
all obstacles. It does not relieve you of the
responsibility to pay 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. G
Risk of injury
Make sure that no persons or animals are
in the manoeuvring range. Otherwise, they
could be injured .
Parktronic is an electronic parking aid. It indi-
cates visually and audibly the distanc e
between your vehicle and an object.
Parktronic is automatically activated when
you switch on the ignition and release the
parking brake.
Parktronic is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
Parktronic monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper. 1
Sensors in the front bumpe rRange of the sensors The sensors must be free of dirt, ice and
slush, otherwise they may not function cor-
rectly. Clean the sensors regularly, taking
care not to scratch or damage them. Side view: Saloon shown as an exampl

0
General notes Thermatic is only operational when the
engine is running. Optimum operation is only
achieved when you drive with the side win-
dows and sliding/tilting sunroof*/panorama
sliding sunroof* closed .
You can allow the air-conditioning system to
adjust automatically or you can adjust it man-
ually.
In automatic mode, Thermatic cools or heats
the vehicle interior according to:
R The selected temperature
R The outside temperature
R The intensity of the sunlight
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the sum-
mer opening feature (Y page 111). This
helps you to achieve the desired interior
temperature more quickly.
The integrated filter filters out most particles
of dust and completely filters out pollen.
i A clogged filter reduces the amount of ai r
supplied to the vehicle interior. For this rea-
son, you should always observe the interval
for replacing the filter, which is specified in
the Service Booklet. As it depends on envi- ronmental conditions, e.g. heavy air pollu-
tion, the interval may be slightly shorter
than stated in the Service Booklet. G
Risk of accident
Follow the settings recommended on the
following pages for heating or cooling. The
windows could otherwise mist up. This may
prevent you from observing the traffic con-
ditions, thereby causing an accident. Activating/deactivating Thermati

It is possible to make use of the residual heat
of the engine to continue heating the station-
ary vehicle for up to 30 minutes after the
engine has been switched off. The heating
time depends on the coolant temperature and
on the interior temperature that has been set.

less of the airflow setting.

G
Risk of accident
If you deactivate the cooling function with
air dehumidification, the vehicle will not be
cooled in warm weather and the air will not
be dehumidified. The windows could mis t
up more quickly. This may prevent you from
observing the traffic conditions, thereby
causing an accident. H
Environmental not
e
The cooling system uses the refrigerant
R134A. This refrigerant does not damage
the earth's ozone layer.
i Condensation may drip from the under-
side of the vehicle when Thermatic is in
cooling mode.
Cooling with dehumidification is operational
when the engine is running, and cools accord -
ing to the interior temperature selected. The
air inside the vehicle is also dried, thereby
preventing the windows from misting up.

Risk of accident
Clear all windows of ice or snow before set-

endanger yourself and others.
i The rear window heating has a high cur-
rent draw. Therefore, switch it off as soon
as the rear window is free of snow and ice,
as it only switches itself off automatically
after between fifteen and thirty minutes.

G
Risk of injury
Never leave children unsupervised in the
vehicle. They could operate the sliding/tilt-
ing sunroof and injure themselves. Alway s
take the key with you when leaving the
vehicle, even if you only leave it for a short
time. G
Risk of injury
Make sure that nobody can become trap -
ped when you are opening and closing the
sliding/tilting sunroof. If danger threatens,
release the switch and push it briefly in any
direction to stop the sliding/tilting sunroof . G
Risk of injury
The glass in the sliding/tilting sunroof
could break in an accident. If you are not
wearing a seat belt, there is a risk that yo u
could be thrown through the opening in the
event of the vehicle overturning. Therefore,
always wear a seat belt to reduce the ris k
of injuries. !
Only open the sliding/tilting sunroof if it
is free of snow and ice. Otherwise, mal-
functions may occur.
Do not allow anything to protrude from the
sliding/tilting sunroof. The seals could oth-
erwise be damaged.
i Resonance noises can occur in addition
to the usual airflow noises when the slid -
ing/tilting sunroof is open. They are caused
by minor pressure fluctuations in the vehi-
cle interior .
Change the position of the sliding/tilting
sunroof or open a side window slightly to
reduce or eliminate these noises .
i It is also possible to open and close the
sliding/tilting sunroof from the outsid e
using the "Summer opening" (Y page 111 )
and "Convenience closing" (Y page 112 )
features respectively .
