If the climate control system is operating in cooling mode, air flows
primarily from the outlets in the center console and in the door
pillars . To achieve adequate cooling, you should never close the

Using climate control economically
Using the climate controls prudently can help save fuel.
When you use the a ir conditioner, engine power is reduced
and fuel consumption increases. To save fuel, you should
use the air conditioner only when necessary . A lso please
note the follow ing po ints:
- If you want to save fuel, activate ECON.
- If yo u are g oing to dr ive wit h the w indows or Panorami c

- If the ve hicle is e xtremely ho t due to the heat of t he s un,
