Warm and cold
Climate control system
Description
The climate control system warms, cools and re­ moves humidity from the air in the vehicle interi­
or. It is the most effective when the windows and
sunroof * are closed. If there is a bui ld-up of heat
inside the vehicle, ventilation can he lp to speed
up the cooling process.
I n all heating mode f unctions except for
defrost ,
the blower only switches to a higher speed once
the engine coolant has reached a sufficient tem­
perature .
Pollutant filt er
The po llutant filter removes poll utants such as
dust and pollen from the a ir .
Ke y recognit ion
The climate control settings are automatically
stored and assigned to the remote contro l key
that is in use .
@) For the sake of the environment
-If you wo uld like to reduce fuel consump­
tion, switch the ai r cond itioning off. This
will a lso reduce em issions.

- In veh icles with a diesel engine, you can
switch the auxiliary heater off in the Info­
tainment system.
(D Tips
- To prevent interference with the heating
and cooling output and to prevent the win­
dows from fogging over, the a ir intake in
front of the windshield must be free of ice,
snow or leaves.
- Condensation from the cooling system can dr ip and form a puddle of water under the
vehicle . This is normal and does not mean
there is a leak .
- If you see that, for example, the seat heat­
ing* or rear w indow defogger are not heat­
ing, the energy management system may
have switched them off temporari ly . These
systems a re available again as soon as the
energy supply has been resto red.

Warm and cold
system operates most efficiently in eco cooling
mode.
A/C MAX cooling mode*
You can switch the maximum cool ing mode on or
off using the rocker switch@. Th e air is not
coo led and humidity is not removed when cooling
mode is switched off. This can cause fog on the

cally when the outside temperature is below
zero. When the cooling mode is switched on, the
vehicle interior is cooled as quickly as possible
and dehumidified .
c:E) Recirculation mode
In recirculation mode, the air inside the vehicle is
circu lated and filtered. This prevents the unfil­

Operating your vehicle
outside the U.S.A. or
Canada
Government reg ulations in the Un ited States and
Canada require that automobiles meet specific
emission regulations and safety standards.
Therefore, vehicles built for the U .S.A. and Cana­
da differ from vehicles sold in other countries.
I f you p lan to take your vehicle outside the conti­
nenta l limits of the United States or Canada,
there is the poss ibility that:
- u nleaded fue ls for vehicles with cata lytic con­
verter may not be available;
- fuel may have a considerably lower octane rat­
i ng. Imprope r fuel may ca use engine damage;
- service may be inadequate due to lack of p roper
service facilities, tools or testing eq uipment;
- r eplacement parts may not be readily ava ilable.
- Navigation systems for veh icles built for the
U .S .A . and Canada will not necessa rily work in
E urope, and may not wo rk in other countries
outside of North Amer ica.
