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

® For the sake of the environment
-If you would like to reduce fuel consump­
t ion, sw itch the air conditioning
off. This
will also reduce emissions.
- 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 air intake in
front of the windshie ld must be free of ice,
snow or leaves.
- Condensation from the cooling system can
dr ip and form a pudd le of water under the
vehicle . This is norma l and does not mean
there is a leak.
- The energy management system may tem­ porarily switch
off certain functions, such as
the seat heating* o r rear window defogger.
T hese systems are ava ilable again as soon
as the ene rgy supply has been restored.

A WARNING
- Never turn off the engine before the veh icle
has come to a comp lete stop . The full func­
t ion of the brake booster and the power
stee ring is not guaranteed. Yo u must use
more force to turn or b rake . Because you
cannot s teer an d brake as you usu ally
would, t his co uld lead to accidents and ser i­
ous in juries.
- Alw ays t ake the key wi th you w henever you
leave you r vehicle . Othe rw ise, the engi ne
cou ld be started o r electrical equipment
s uch as the power windows cou ld be operat­
ed . This can lead to se rious injury.
- For safety reasons, always park the vehicle
with the se lector lever in the P position
(a u­
tomat ic transmission) or with 1st gear en­
gaged (manual transmission). Otherwise
the vehicle could roll away u nintent ionally .
(D Note
If the eng ine has been under heavy load for
an extended per iod of t ime, heat builds up in
the engine compartment after the engine is
sw itched off and there is a risk of damaging
the engi ne . For this reason, let the engi ne run
for at idle for approximately two minutes
be­
fore shutting it off.

(D Tips
Fo r u p to 10 minutes after stopping the en­
g ine, the radiator fan may turn on again auto­
matically or it may continue to r un (even if
the ig nition is switched off) for the following
r easons:
- The coolant temperature is increas ing due
to trapped heat.
- If the eng ine is wa rm and the eng ine com­
partment a lso heats up from strong sun­
light .
- Applies to: vehicles with diesel particulate
filter: The emissions control system is heat­
ed through the regeneration process, even if
the engine has not reached its operat ing
tempe rature yet.
