Warm and cold Climate control system
Description
A ppl ies to: ve hicles wit h 3-z on e del uxe automatic cl imate
co ntrol or 4 -zo ne de luxe automa tic cl imate co ntr ol
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 veh icle, ventilat ion can help to speed
up the cooling process.
In all heating mode functions except for
defrost,
the blower on ly switches to a higher speed once
the eng ine coolant has reached a sufficient tem
perature.
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air .
Key recognition
The climate control settings are automatically
stored and assigned to the remote control key
that is in use.
Warm and cold
(®} For the sake of the environment
-If you would like to reduce fuel consump
tion, switch the air conditioning off. This
will also reduce emissions.
- In vehicles 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 windshield must be free of ice,
snow or leaves.
- Condensation from the cooling system can
drip and form a puddle of water under the
vehicle. This is normal and does not mean
there is a leak.
- The energy management system may tem
porarily switch off certain functions, such as
the seat heating* or rear window defogger.
These systems are available again as soon
as the energy supply has been restored.
